-This document is the authoritative policy for handwritten production and test Java
-in `agiledancers-be`. Generated code and Java helpers outside that module are out
-of scope. Existing frontend conventions in README.md and agiledancers-fe remain in force.
+Read [the pinned engineering standards](generated/CODING_STANDARDS.md) before
+changing Java. Their backend-module placeholder means `agiledancers-be` here.
+Frontend conventions remain in README.md and agiledancers-fe.
 
-## Scope and authority
+The existing maintainer-approved exception for Group's eight-parameter canonical
+constructor remains in `tooling/standards/waivers.tsv`. No new waiver is introduced
+by S19. For reviews also read [the local companion](docs/backend-review.md).
 
-- Cover handwritten production and test Java in `agiledancers-be`. Exclude
-  generated code. Dependency injection and production architecture rules apply
-  where relevant. Frontend and Java helpers outside the backend are out of scope.
-- [Java coding guidelines](https://www.geeksforgeeks.org/java/coding-guidelines-in-java/)
-  supplied source material. Only the rules adopted in this local document apply;
-  changes to the article do not change project policy.
-- The project's pinned Palantir formatter wins formatting conflicts, including
-  comment layout. S8 remains responsible for formatter integration.
-- Do not adopt unrelated static-analysis rule bundles.
-
-## Java conventions
-
-- Types use UpperCamelCase; methods and variables use lowerCamelCase; constants
-  use UPPER_SNAKE_CASE; package names are lowercase.
-- One top-level type per file; explicit member visibility; `@Override` on
-  overriding methods. Do not invent visibility modifiers where Java forbids them.
-- Opening braces stay on the declaration/control-statement line. All `if`, `for`
-  and `while` bodies require braces, including enhanced for and do/while bodies.
-- No wildcard imports. Static imports are allowed only in test classes.
-- Comments explain intent or constraints. Document public contracts with Javadoc
-  where their meaning is not clear from the declaration; do not require boilerplate
-  documentation for every accessor.
-- Block comments use the following layout, subject to Palantir formatting:
-
-  ```java
-  /*
-      This is an example of a block comment.
-      It may have more than one line.
-  */
-  ```
-- Prefer records for immutable data carriers. Classes are allowed when mutation,
-  framework requirements or inheritance make records unsuitable. Preserve API and
-  serialization behavior. Record immutability is shallow: protect mutable
-  components appropriately.
-- Require `final` for parameters, local variables and fields wherever they can
-  remain assigned once, including loop variables and catch parameters where Java
-  permits it. Field finality must remain compatible with framework injection and
-  lifecycle requirements. Permit reassignment when the algorithm needs it; do not
-  introduce artificial holder objects to avoid reassignment. This rule does not
-  require final classes or methods.
-- Use explicit types unless the initializer visibly identifies the type. `var` is
-  allowed with `new School(...)` or an explicit cast, but not for method results,
-  literals or other inferred expressions. For example,
-  `final var school = new School(...)` is allowed, while a repository result uses
-  `final School school = repository.find(id)`. Borderline cases require review.
-- No additional member-ordering or line-width policy beyond Palantir.

-## Metrics
-
-Targets guide development. Review signals require assessment, not automatic
-failure. Blocking limits fail verification. Strict inequalities matter: a value
-exactly at a blocking limit passes.
-
-| Metric | Target | Review signal | Blocking limit |
-| --- | ---: | ---: | ---: |
-| Cyclomatic complexity per method/constructor | ≤ 5 | > 7 | > 10 |
-| Cognitive complexity per method/constructor | ≤ 10 | > 10 | > 15 |
-| Method/constructor length, code lines | ≤ 20 | > 30 | > 50 |
-| Parameters per method | ≤ 3 | > 4 | > 5 |
-| Parameters per explicitly written constructor | ≤ 4 | > 5 | > 7 |
-| Injected dependencies per class | ≤ 4 | > 5 | > 7 |
-| Fan-out per class, unique used types | ≤ 10 | > 15 | Review only |
-| Own superclass depth, excluding Object | ≤ 1 | > 2 | > 3 |
-| Control-flow nesting | ≤ 2 | > 3 | > 4 |
-| Production duplicated lines density | ≤ 1% | > 1% | > 3% |
-| Class length, code lines | ≤ 200 | > 300 | > 500 |
-| Declared public methods per class, excluding trivial accessors | ≤ 10 | > 15 | Review only |
-
-### Measurement definitions
-
-- Use the pinned PMD algorithms as authoritative for cyclomatic and cognitive
-  complexity. Document their exact configuration, including switch and boolean
-  treatment. Do not accidentally introduce a class-level aggregate complexity gate.
-- Measure each method, constructor and explicitly written record constructor
-  independently. Lambda bodies contribute to their enclosing executable;
-  methods in nested/local classes are separate executables.
-- Parameter limits exclude implicit record constructors and generated members.
-  Record component counts remain a design review concern.
-- Length means physical source lines after Palantir formatting, excluding blank
-  and comment-only lines. Declaration and brace-only lines count; a line containing
-  both code and comments counts. Do not substitute statement counts or NCSS.
-  Measure nested types separately and exclude them from enclosing class length.
-- Count distinct injected collaborators by resolved type and qualifier. Include
-  constructor, field, setter, inherited and implicit constructor injection.
-  Repeated injection of the same type and qualifier counts once; differently
-  qualified instances of the same type count separately.
-- Fan-out counts distinct explicitly referenced resolved types, including JDK and
-  framework types. Exclude primitives, the class itself and generated references.
-- Inheritance depth counts project-owned superclass layers; exclude Object,
-  interfaces and external framework ancestry.
-- Nesting combines `if`, loops, `switch` and `catch`, with the first structure at
-  depth one. An `else if` chain stays at one level. `else`, `try` and `finally`
-  add no level themselves. Lambdas retain surrounding depth; methods in nested
-  classes start fresh.
-- Public-method counts include explicitly declared public instance and static
-  methods; exclude constructors, inherited methods and trivial accessors. A
-  trivial accessor only reads or assigns its corresponding field, with no
-  validation, branching or other work.
-- Duplication limits apply only to production code. Duplication in tests is allowed
-  and has no target, review signal or blocking limit.
-- Detect production clones with CPD, minimum 100 tokens, without ignoring
-  identifier or literal differences. Density is
-  `100 × distinct duplicated code-line locations / all production code-line locations`.
-  Exclude blank/comment-only lines from numerator and denominator. Count every
-  occurrence, including the first; merge overlapping ranges to count each source
-  line once. This project metric need not equal a future Sonar metric.
-
-## Enforcement and developer workflow
-
-- Use explicitly pinned Java-25-compatible Checkstyle and PMD/CPD versions.
-  Retain ArchUnit for architecture checks and add small targeted custom checks
-  where standard rules cannot accurately express the agreed semantics.
-- Automate every blocking metric and explicit rule where reliable checking is
-  available. Identify rules requiring manual review explicitly; do not claim
-  they are automated. Review signals must appear in reports even when builds pass.
-- Run standards checks during `mvn verify`; provide documented standalone commands.
-  Ordinary compile/test commands retain the current S8 formatting behavior.
-- Standards checks report violations without rewriting code. CI passes these
-  checks before image publication. Parser failures or unsupported Java constructs
-  fail with the affected path and actionable diagnostics, rather than being skipped.
-- Add a root AGENTS.md instruction requiring agents to read CODING_STANDARDS.md
-  before changing backend Java. Project review instructions must explicitly cover
-  manual rules, review signals in changed code and approved waivers, without
-  repeating checks already enforced by tooling.
-- Keep upstream skill files unchanged. Put project-specific code-review guidance
-  in a companion file referenced by project instructions and used alongside
-  `skills/code-review/SKILL.md`.
-- Waivers must be explicit, narrowly scoped and carry a recorded reason alongside
-  code or configuration. Agents need maintainer agreement before introducing one.
-  No blanket suppressions, exclusions of difficult files or weakened thresholds
-  merely to make verification pass.
-
-## Coverage
-
-- Require at least 80% backend line coverage across handwritten production code
-  for the module as a whole, not separately per class or package. Compare the
-  unrounded percentage against 80%.
-- Local `mvn verify` must reach 80% using backend unit/integration tests alone.
-  This intentionally tightens the original combined-tests-only requirement.
-- CI additionally instruments the backend exercised by Playwright, merges that
-  coverage with backend unit/integration coverage and gates the combined result.
-  The Playwright contribution need not separately reach 80%.
-- Exclude generated code only; do not broadly exclude DTOs, configuration or
-  difficult code. Publish line and branch coverage reports; branch coverage has
-  no agreed blocking percentage.
-- PIT measures mutation-test effectiveness, not line coverage, and is outside
-  S7's required implementation. Configuring Sonar in the pipeline remains out of
-  scope for S14. FindBugs/SpotBugs is not an additional required check suite.
-
-
-## Implemented checks and manual review
-
-Checkstyle **12.3.1**, PMD/CPD **7.28.0**, and JaCoCo **0.8.14** are pinned.
-`tooling/standards/checkstyle.xml` selects individual naming, structure, import and brace checks; no general analysis bundle is enabled.
-`tooling/standards/src/main/java/Standards.java` supplies the targeted measurements.
-ArchUnit remains in the backend test suite for architectural boundaries.
-
-PMD uses Java 25, the running JDK's `jrt-fs.jar`, compiled backend classes and the
-resolved test dependency classpath. Cyclomatic complexity uses PMD's default
-options: boolean paths count, assertions do not. Decisions include if/loops,
-catch, ternary and throw; non-default switch alternatives count individually,
-including comma-separated labels. There is no aggregate class-complexity gate.
-Cognitive complexity uses PMD's boolean-operation sequences, nesting, switch,
-recursion and flow rules. The scoped visitors retain those algorithms while
-including lambdas in their enclosing executable and excluding nested/local type
-bodies, whose methods are measured independently. Compact record constructors
-use the same visitors and start with cyclomatic complexity one.
-
-Custom checks measure physical code lines from regular parser tokens, including
-brace/declaration lines and mixed code/comment lines. They count multiline literal
-lines while excluding physically blank lines. Class length excludes nested-type
-tokens, preserving lines shared with enclosing code. Other custom measurements
-implement the definitions above: nesting, resolved type fan-out, project-owned
-superclass depth, public non-accessor methods, and injected collaborators.
-Injection includes inherited fields/setters, explicit `@Inject` constructors,
-single constructors on bean classes, records' implicit canonical constructors,
-and Lombok required/all-argument constructor injection. Qualifier keys use resolved
-annotation names and values, including defaults; repeat sites are deduplicated.
-The CPD configuration preserves identifiers/literals, uses 100 tokens and disables
-skip blocks. Its line-location union counts overlapping occurrences only once.
-
-Checkstyle and targeted checks enforce import/brace/naming/visibility rules,
-`@Override`, visible constructor/cast/new-array `var` initializer forms, final parameters, locals (including
-loops/catches and lambdas) and initialized fields. PMD's three selected finality
-rules additionally cover control-flow assignment and private constructor-initialized
-fields. Framework/lifecycle requirements, generated Lombok setters, and external
-writes to public/protected fields need review before changing field finality.
-No tool can infer whether a comment explains intent, whether a public contract
-needs Javadoc, whether a record is appropriate, or whether mutable components are
-sufficiently protected. These are **manual rules**, as are ambiguous type inference
-and architecture/DI design decisions. Review all `DESIGN` record-component entries
-and `REVIEW` signals, even when a build passes, using `docs/backend-review.md`.
-
-Reports never rewrite Java. Formatter application remains S8's separate validate
-execution. Generated output under `target` and generated source directories are
-outside the handwritten `src/main/java` and `src/test/java` scope. No maintained
-file, DTO, configuration class or package is excluded from standards or coverage.
-JaCoCo filters compiler/Lombok-generated members; no handwritten-code exclusions
-are configured. Line and branch results are published, with only lines gated.
-
-Exact metric waivers live in `tooling/standards/waivers.tsv`; each records a metric,
-fully resolved executable signature (or class), exact retained value and the
-maintainer agreement/reason. No wildcard waivers are allowed, and a changed value
-fails again. A waived blocking result remains visible as `WAIVER`. PMD suppression
-annotations/comments cannot silently waive a rule. The only approved waiver is the eight-parameter `Group` canonical constructor,
-which preserves its JSON contract while defensively copying both lists. Adding a waiver always requires maintainer agreement.
-
-## Commands and reports
-
-Run from the root with JDK 25:
-
-```sh
-mvn -Dformat.mode=check clean verify
-# Prepare standalone analysis without running tests:
-mvn -pl agiledancers-be test-compile dependency:build-classpath@standards-classpath
-mvn -f tooling/standards/pom.xml test exec:java
-# Exact local coverage gate after a test/report build:
-java tooling/coverage/Coverage.java agiledancers-be/target/site/jacoco/jacoco.xml
-```
-
-`verify` runs backend tests, builds resolved analysis inputs, generates JaCoCo
-reports, runs checker regression tests and standards analysis, then gates exact
-module-wide line coverage. `compile` and `test` retain existing formatting behavior
-and do not run the verify-only standards checks. Standalone analysis requires its
-classpath preparation; unresolved types fail with the path and preparation advice.
-
-Full metrics and findings: `agiledancers-be/target/standards/report.txt`.
-Checker regression results: `tooling/standards/target/surefire-reports`.
-Coverage HTML/XML/CSV: `agiledancers-be/target/site/jacoco` (local backend tests)
-and `agiledancers-be/target/site/jacoco-combined` (merged browser contribution).
-The gate compares integer line counts (`5 * covered >= 4 * total`), rejecting an
-empty report and percentages that would round up to 80%.
-
-CI first passes local verify. It mounts the pinned JaCoCo agent into its disposable
-backend test container, exposes the agent only on the isolated Docker network,
-and uses the pinned CLI to dump `target/playwright.exec` after Playwright. A missing
-or empty dump fails. The following commands merge both datasets and gate the result
-before the verified-commit marker can authorize publication:
-
-```sh
-mvn -pl agiledancers-be jacoco:merge@combined jacoco:report@combined-report exec:exec@combined-coverage
-```
-
-CI retains both coverage reports, execution data, standards findings and regression
-results with its usual diagnostics artifacts. The agent is mounted only for tests;
-published images contain no agent. PIT and Sonar configuration remain outside S7.
-See `specs/S7-validation.md` for migration evidence and retained-signal assessment.

+Engineering v2.0.0 at `46df72f008113d0ed683a6c7344b1d7309564d84` is pinned and committed.
+Regeneration and bootstrap --check passed against the published tag and full commit.
+Shared engineering tests passed: 8 bootstrap/generator, 21 CI and 34 release tests;
+formatter integration passed. Java launcher documentation, varargs and console API updated.
+
+Workflows use the shared user-scoped mini-pc runner for wanjakrah. It serves current
+and future repositories without per-project registration. Skills are maintained in
+landscape/skills/ and project agent instructions reference those workflows.
+Project deployment credentials and runtime configuration remain application-owned.

+- Full Maven verification: 73 backend tests and 19 standards regression tests.
+  Existing approved waiver retained; no new waiver or threshold change.
+- Full shared pipeline: frontend lint/build, 32 frontend tests, 4 Playwright
+  tests, both prebuilt Docker images and combined backend coverage
+  1771/1841 (96.20%).
+- Standalone backend and frontend Docker source builds passed. The backend used
+  a disposable PostgreSQL container and BuildKit secrets for test configuration.
+- Shared CI/release regression suites: 19 and 34 tests respectively.
+- Engineering bootstrap/generator suite: 7 tests, covering all component choices,
+  actual Maven regeneration with generated/ absent, drift including new files,
+  obsolete-file removal, moved tags and preservation of project-owned files.
+- Formatter integration checks passed. Upstream skills and attribution files
+  match their source snapshot byte for byte; only the skills index was adapted.
+- A separate generated example passed its common pipeline and a real isolated
+  deployment of two synthetic revisions followed by rollback. Production was
+  not used. See engineering's VALIDATION.md and tests/acceptance.py.
+
+Gitea build-run evidence for the migrated application commit is recorded with
+S19 in landscape. Its workflow checks the pinned release before invoking the
+same shared pipeline. Checkout and committed generated resources require no
+sibling repository checkout.
+
+Production deployment is a separate action. Live NAS SSH authentication,
+production credentials and rollback against pre-S19 retained releases were not
+exercised. The existing Compose project, database volume and release-state schema
+remain compatible. Legacy releases without retained health.sh use the current
+application health function; review that compatibility before production rollback.

+PMD uses Java 25, the running JDK's `jrt-fs.jar`, compiled backend classes and the
+resolved test dependency classpath. Cyclomatic complexity uses PMD's default
+options: boolean paths count, assertions do not. Decisions include if/loops,
+catch, ternary and throw; non-default switch alternatives count individually,
+including comma-separated labels. There is no aggregate class-complexity gate.
+Cognitive complexity uses PMD's boolean-operation sequences, nesting, switch,
+recursion and flow rules. The scoped visitors retain those algorithms while
+including lambdas in their enclosing executable and excluding nested/local type
+bodies, whose methods are measured independently. Compact record constructors
+use the same visitors and start with cyclomatic complexity one.
 
-## Implementation handoff
+Custom checks measure physical code lines from regular parser tokens, including
+brace/declaration lines and mixed code/comment lines. They count multiline literal
+lines while excluding physically blank lines. Class length excludes nested-type
+tokens, preserving lines shared with enclosing code. Other custom measurements
+implement the definitions above: nesting, resolved type fan-out, project-owned
+superclass depth, public non-accessor methods, and injected collaborators.
+Injection includes inherited fields/setters, explicit `@Inject` constructors,
+single constructors on bean classes, records' implicit canonical constructors,
+and Lombok required/all-argument constructor injection. Qualifier keys use resolved
+annotation names and values, including defaults; repeat sites are deduplicated.
+The CPD configuration preserves identifiers/literals, uses 100 tokens and disables
+skip blocks. Its line-location union counts overlapping occurrences only once.
 
-This specification records the agreed design. Updating it does not implement
-checks, change agent instructions, refactor application code or establish current
-coverage. Those are implementation work, with evidence required above.
+Checkstyle and targeted checks enforce import/brace/naming/visibility rules,
+`@Override`, visible constructor/cast/new-array `var` initializer forms, final parameters, locals (including
+loops/catches and lambdas) and initialized fields. PMD's three selected finality
+rules additionally cover control-flow assignment and private constructor-initialized
+fields. Framework/lifecycle requirements, generated Lombok setters, and external
+writes to public/protected fields need review before changing field finality.
+Comment intent, Javadoc adequacy for nontrivial public contracts, record suitability
+and protection of mutable components require manual review. These are **manual
+rules**, as are ambiguous type inference, architecture/DI design decisions, NIO
+API selection, trailing-array varargs, console I/O selection and the POJO
+documentation boundary. Review all `DESIGN` record-component entries
+and `REVIEW` signals, even when a build passes, using `docs/backend-review.md`.
 
-## Implementation evidence
+Reports never rewrite Java. Formatter application remains S8's separate validate
+execution. Generated output under `target` and generated source directories are
+outside the handwritten `src/main/java` and `src/test/java` scope. No maintained
+file, DTO, configuration class or package is excluded from standards or coverage.
+JaCoCo filters compiler/Lombok-generated members; no handwritten-code exclusions
+are configured. Line and branch results are published, with only lines gated.
 
-Implementation and verification are recorded in `specs/S7-validation.md`; retained
-review signals and the sole approved waiver are recorded in
-`specs/S7-review-signals.txt` and `tooling/standards/waivers.tsv`.
+Exact metric waivers live in `tooling/standards/waivers.tsv`; each records a metric,
+fully resolved executable signature (or class), exact retained value and the
+maintainer agreement/reason. No wildcard waivers are allowed, and a changed value
+fails again. A waived blocking result remains visible as `WAIVER`. PMD suppression
+annotations/comments cannot silently waive a rule. Adding a waiver always requires maintainer agreement.
 
-The maintainer approved GroupDetails-based Java service signatures and the exact
-eight-parameter Group constructor waiver in the implementation conversation.
-REST/JSON contracts remain unchanged. Clean verify and browser/combined coverage
-checks pass. The implementation is ready for project review.
+## Commands and reports
+
+Run from the root with JDK 25:
+
+```sh
+mvn -Dformat.mode=check clean verify
+# Prepare standalone analysis without running tests:
+mvn -pl <backend-module> test-compile dependency:build-classpath@standards-classpath
+mvn -f generated/tooling/standards/pom.xml test exec:java
+# Exact local coverage gate after a test/report build:
+java generated/tooling/coverage/Coverage.java <backend-module>/target/site/jacoco/jacoco.xml
+```
+
+`verify` runs backend tests, builds resolved analysis inputs, generates JaCoCo
+reports, runs checker regression tests and standards analysis, then gates exact
+module-wide line coverage. `compile` and `test` retain existing formatting behavior
+and do not run the verify-only standards checks. Standalone analysis requires its
+classpath preparation; unresolved types fail with the path and preparation advice.
+
+Full metrics and findings: `<backend-module>/target/standards/report.txt`.
+Checker regression results: `generated/tooling/standards/target/surefire-reports`.
+Coverage HTML/XML/CSV: `<backend-module>/target/site/jacoco` (local backend tests)
+and `<backend-module>/target/site/jacoco-combined` (merged browser contribution).
+The gate compares integer line counts (`5 * covered >= 4 * total`), rejecting an
+empty report and percentages that would round up to 80%.
+
+CI first passes local verify. It mounts the pinned JaCoCo agent into its disposable
+backend test container, exposes the agent only on the isolated Docker network,
+and uses the pinned CLI to dump `target/playwright.exec` after Playwright. A missing
+or empty dump fails. The following commands merge both datasets and gate the result
+before the verified-commit marker can authorize publication:
+
+```sh
+mvn -pl <backend-module> jacoco:merge@combined jacoco:report@combined-report exec:exec@combined-coverage
+```
+
+CI retains both coverage reports, execution data, standards findings and regression
+results with its usual diagnostics artifacts. The agent is mounted only for tests;
+published images contain no agent. PIT and Sonar configuration remain outside S7.
+Application validation evidence and retained-signal assessments stay in the consuming project.

+# Backend review companion
+
+Use alongside landscape's `skills/code-review/SKILL.md` and `generated/CODING_STANDARDS.md`.
+
+Review changed code for intent-revealing comments, missing public-contract Javadoc,
+appropriate record use, defensive copying of mutable record components, and
+compatibility with APIs, JSON and persistence. Assess ambiguous `var` initializers
+and framework/lifecycle exceptions to field finality. Confirm architecture and
+injection decisions make sense for production and tests. Check NIO API preference,
+varargs for trailing array parameters, and Java 25 IO use for direct console
+input/output; retain System.err for diagnostics. Require Javadoc for public
+classes and methods beyond basic POJO/data-carrier behavior.
+
+Read standards reports even when verification passes. Assess every review signal
+in changed code, including fan-out, public methods and record component counts.
+Record a rationale for retained signals in application validation evidence or the change description.
+Check narrowly scoped waivers against recorded maintainer agreement and reason.
+Never introduce blanket exclusions or weaken thresholds to pass a build.
+Do not repeat mechanical checks already enforced by tooling; verify their result.

+MIT licensed. See [LICENSE.wanjakrah](LICENSE.wanjakrah) and
+[ATTRIBUTION.md](ATTRIBUTION.md).
+
+Requires Git, JDK 25 on `PATH`, and a Unix-like system with `env -S`.
+Run from the repository you want to clean (including any subdirectory):
+
+```sh
+./git-tools/pruneLocalBranches --check
+./git-tools/pruneLocalBranches -d feature/example
+./git-tools/pruneLocalBranches -d '*'
+./git-tools/pruneLocalBranches --help
+```
+
+From another repository, use the absolute path to this script. Its location does
+not select the repository; the current working directory does. Always quote `'*'`.
+Alternatively launch with `java --source 25 /path/to/pruneLocalBranches ...`.
+
+The script fetches all origin branches and prunes stale **local** origin tracking
+references. A failed fetch stops the operation. It never pushes, deletes remote
+branches, removes folders, or changes working files.
+
+A local branch is eligible only when no same-name branch exists on origin, it is
+not checked out in any worktree, and all its commits are reachable from the current
+`HEAD` or local `main`. Configured upstream names do not affect this decision:
+`S6-deployment` tracking `origin/main` is not protected by that mapping. If local
+`main` is missing, only `HEAD` counts. Neither local branch is updated by fetching.
+Squash/rebase merges can leave different commit identities, so these branches may
+be refused even when their changes were merged. The refusal lists the commits.
+Checked-out branches are always refused, protecting their uncommitted work too.
+
+`--check` prints eligibility and protection reasons. Deletion prints the candidates
+and requires exactly `DELETE`; any other response or end of input cancels. Bulk
+deletion skips protected branches and reports why. Before each deletion the script
+rechecks eligibility and verifies that the branch still points to the displayed
+commit. Avoid concurrent Git operations while running it; bulk deletion is not
+atomic, so an error can leave earlier candidates already deleted.
+
+Implementation: a Java 25 compact source file runs Git through `ProcessBuilder`
+without a shell. After the explicit safety checks, `git branch -D` removes the local
+ref, bypassing Git's separate upstream-based merge check. No build or dependencies
+are needed. Exit codes: `0` success or cancellation, `1` error/blocked deletion,
+`2` invalid arguments.
+
+Run the isolated integration checks with
+`python3 git-tools/test-prune-local-branches.py`. They create temporary repositories
+under the system temporary directory, print their location for inspection, and
+exercise single/bulk deletion, protection rules, cancellation and fetch failures.

-description: "Review the changes since a fixed point (commit, branch, tag, or merge-base) along two axes: Standards (does the code follow this repo's documented coding standards?) and Spec (does the code match what the originating issue/spec asked for?). Runs both reviews in parallel sub-agents and reports them side by side. Use when the user wants to review a branch, a PR, work-in-progress changes, or asks to \"review since X\"."
----
-
-Two-axis review of the diff between `HEAD` and a fixed point the user supplies:
-
-- **Standards**: does the code conform to this repo's documented coding standards?
-- **Spec**: does the code faithfully implement the originating issue / spec?
-
-Both axes run as **parallel sub-agents** so they don't pollute each other's context, then this skill aggregates their findings. Start every sub-agent with a fresh context window.
-
-The issue tracker should have been provided to you. If not, tell the user to run `/setup-matt-pocock-skills`.
-
-## Process
-
-### 1. Pin the fixed point
-
-Whatever the user said is the fixed point (a commit SHA, branch name, tag, `main`, `HEAD~5`, etc.). If they didn't specify one, ask for it.
-
-Capture the diff command once: `git diff <fixed-point>...HEAD` (three-dot, so the comparison is against the merge-base). Also note the list of commits via `git log <fixed-point>..HEAD --oneline`.
-
-Before going further, confirm the fixed point resolves (`git rev-parse <fixed-point>`) and the diff is non-empty. A bad ref or empty diff should fail here, not inside two parallel sub-agents.
-
-### 2. Identify the spec source
-
-Look for the originating spec, in this order:
-
-1. Issue references in the commit messages (`#123`, `Closes #45`, GitLab `!67`, etc.), fetched via the workflow in the tracker doc.
-2. A path the user passed as an argument.
-3. A spec file under `docs/`, `specs/`, or `.scratch/` matching the branch name or feature.
-4. If nothing is found, ask the user where the spec is. If they say there isn't one, the **Spec** sub-agent will skip and report "no spec available".
-
-### 3. Identify the standards sources
-
-Search the repo for every file that documents how code should be written. When `CODING_STANDARDS.md` or `CONTRIBUTING.md` exists, it must be on the list.
-
-On top of whatever the repo documents, the Standards axis always carries the **smell baseline** below: a fixed set of Fowler code smells (_Refactoring_, ch.3) that applies even when a repo documents nothing. Two rules bind it:
-
-- **The repo overrides.** A documented repo standard always wins; where it endorses something the baseline would flag, suppress the smell.
-- **Always a judgement call.** Each smell is a labelled heuristic ("possible Feature Envy"), never a hard violation. Like any standard here, skip anything tooling already enforces.
-
-Each smell reads *what it is* → *how to fix*; match it against the diff:
-
-- **Mysterious Name**: a function, variable, or type whose name doesn't reveal what it does or holds. → rename it; if no honest name comes, the design's murky.
-- **Duplicated Code**: the same logic shape appears in more than one hunk or file in the change. → extract the shared shape, call it from both.
-- **Feature Envy**: a method that reaches into another object's data more than its own. → move the method onto the data it envies.
-- **Data Clumps**: the same few fields or params keep travelling together (a type wanting to be born). → bundle them into one type, pass that.
-- **Primitive Obsession**: a primitive or string standing in for a domain concept that deserves its own type. → give the concept its own small type.
-- **Repeated Switches**: the same `switch`/`if`-cascade on the same type recurs across the change. → replace with polymorphism, or one map both sites share.
-- **Shotgun Surgery**: one logical change forces scattered edits across many files in the diff. → gather what changes together into one module.
-- **Divergent Change**: one file or module is edited for several unrelated reasons. → split so each module changes for one reason.
-- **Speculative Generality**: abstraction, parameters, or hooks added for needs the spec doesn't have. → delete it; inline back until a real need shows.
-- **Message Chains**: long `a.b().c().d()` navigation the caller shouldn't depend on. → hide the walk behind one method on the first object.
-- **Middle Man**: a class or function that mostly just delegates onward. → cut it, call the real target direct.
-- **Refused Bequest**: a subclass or implementer that ignores or overrides most of what it inherits. → drop the inheritance, use composition.
-
-### 4. Spawn both sub-agents in parallel
-
-Issue both sub-agent calls together, in the foreground, and aggregate the reports they return.
-
-**Standards sub-agent prompt** should include:
-
-- The full diff command and commit list.
-- The list of standards-source files you found in step 3, **plus the smell baseline from step 3** pasted in full (the sub-agent has no other access to it).
-- The brief: "Report, per file/hunk where relevant, (a) every place the diff violates a documented standard: cite the standard (file + the rule); and (b) any baseline smell you spot: name it and quote the hunk. Distinguish hard violations from judgement calls: documented-standard breaches can be hard, but baseline smells are always judgement calls, and a documented repo standard overrides the baseline. Skip anything tooling enforces. Under 400 words."
-
-**Spec sub-agent prompt** should include:
-
-- The diff command and commit list.
-- The path or fetched contents of the spec.
-- The brief: "Report: (a) requirements the spec asked for that are missing or partial; (b) behaviour in the diff that wasn't asked for (scope creep); (c) requirements that look implemented but where the implementation looks wrong. Quote the spec line for each finding. Under 400 words."
-
-If the spec is missing, skip the Spec sub-agent and note this in the final report.
-
-### 5. Aggregate
-
-Present the two reports under `## Standards` and `## Spec` headings, verbatim or lightly cleaned. Do **not** merge or rerank findings, because the two axes are deliberately separate (see _Why two axes_).
-
-End with a one-line summary: total findings per axis, and the worst issue _within each axis_ (if any). Don't pick a single winner across axes: that's the reranking the separation exists to prevent.
-
-## Why two axes
-
-A change can pass one axis and fail the other:
-
-- Code that follows every standard but implements the wrong thing → **Standards pass, Spec fail.**
-- Code that does exactly what the issue asked but breaks the project's conventions → **Spec pass, Standards fail.**
-
-Reporting them separately stops one axis from masking the other.

-Interview the user relentlessly until you reach a shared understanding. Map this as a **design tree**: every decision branches into the decisions that hang off it.
-
-Work the tree in **rounds**. The **frontier** is every decision whose prerequisites are already settled: the questions you can ask _now_ without guessing at answers you haven't heard yet.

-Finding _facts_ is your job, never the user's. When a frontier question needs a fact from the environment (filesystem, tools, etc.), dispatch a sub-agent to find it; don't ask the user for anything you could look up yourself.

The _decisions_ are the user's: put each to them and wait.
-
-The session is done when the frontier is empty: every branch of the design tree visited, nothing left silently assumed. Do not act on it until the user confirms you have reached a shared understanding.

-# S12 — Asynchronous feedback for scheduling
-
-Status: IMPLEMENTED
-
-Agreed after the grill-me interview; shared understanding confirmed.
-
-## User story
-
-As a dance-school maintainer, I want feedback after starting Schedule Groups,
-so that I can see whether the backend is still calculating, when it finishes
-and what the outcome is, including when I leave and return to the show page.
-
-## Background execution and concurrency
-
-- Start scheduling in the backend without keeping the initiating HTTP request
-  open until the calculation finishes. Navigation, page reloads and disconnected
-  clients must not stop the calculation.
-- The backend owns the current scheduling status for each show. All open
-  screens see the same status, including screens that did not start the run.
-- Allow at most one active calculation per show. Disable Schedule Groups while
-  it is running and reject duplicate starts in the backend as well.
-- Different shows may calculate concurrently. A global capacity limit and a
-  waiting queue are outside S12.
-- Retain the existing 30-minute solver limit and scheduling rules.
-
-## Progress and outcomes
-
-- While running, show elapsed time, the current optimization phase (attendance,
-  spread or variety), and whether a valid solution has been found.
-- Report a valid solution as soon as the solver discovers one, including during
-  a phase. Extend solver progress reporting rather than waiting for the phase
-  to finish. Do not apply intermediate solutions.
-- Do not present a completion percentage or estimated finish time: the phases
-  do not represent proportional parts of the calculation time.
-- Keep the latest status and outcome per show until a new calculation starts.
-  Show the finish time and distinguish an optimal solution from a valid solution
-  whose optimality was not proven within the time limit.
-- For a successful result, show a concise summary with concrete results for
-  attendance, spread and variety, using understandable labels.
-- Clearly distinguish invalid input, infeasibility, solver failure, time limit
-  without a valid solution and rejection because inputs changed. Explain why
-  no result was applied and that existing assignments were preserved.
-  Backend-restart interruption recovery belongs to S16.
-
-## Applying results
-
-- Retain the confirmation before starting that explains replacement of existing
-  assignments. A successful completed calculation automatically replaces them;
-  no preview/apply step is introduced.
-- A valid solution may be applied when the time limit expires even if optimality
-  has not been proven.
-- Preserve the existing scheduling input revision check. A result based on
-  outdated inputs must not replace the current assignments.
-- Failed, infeasible, interrupted, stale and no-solution calculations preserve
-  existing assignments.
-- Report success only after the resulting assignments have been saved. Keep
-  status and saved results consistent.
-
-## Server-sent events and connection recovery
-
-- Use server-sent events (SSE) for backend-to-frontend status updates.
-- On initial connection and reconnection, provide the current backend status.
-  Correctness must not depend on receiving every previous event.
-- Maintain updates across navigation within the application so completion
-  notifications can appear outside the show page.
-- If the connection is lost, indicate that displayed status may be outdated
-  while the backend calculation continues. Reconnect and reconcile with the
-  current status when connectivity returns.
-- Configure the application's proxy for streaming so updates reach the client
-  promptly rather than being buffered until completion.
-
-## Completion notifications
-
-- Show an application-wide snackbar when a calculation completes or fails,
-  including when the user has navigated to another application page.
-- Include the show name, a short outcome and a View show action.
-- Phase changes update progress without generating snackbars.
-- After temporary connection loss, show a missed completion notification once
-  when the connection recovers. Reconnection must not repeatedly notify for
-  the same completion.
-- Do not replay old snackbars on page reload or reopening the application;
-  show the retained status on the show page instead.
-- Email, browser notifications and notifications outside the application are
-  outside S12.
-
-## Persistence and backend restarts
-
-The maintainer explicitly transferred durable scheduling status and recovery
-following backend restarts to [S16](../in_review/S16_store-state-in-persistent-storage)
-when completing S12. The latest status and outcome in S12 survive navigation,
-page reloads and SSE reconnection while the same backend process remains active.
-Schools, assignments and scheduling status currently remain in memory.
-
-S16 owns PostgreSQL storage of the latest run, atomic persistence of saved
-assignments and completed status, and startup recovery of previously running
-calculations as Interrupted without automatic resumption. Previously saved
-results must survive restart under S16. These are not completion criteria for S12.
-Distributed execution and scheduling on another PC remain in S13.
-
-## Out of scope
-
-- Cancelling a calculation or applying an intermediate solution.
-- History of earlier calculations beyond the latest status and outcome.
-- Global capacity limits, queues and remote workers.
-- Changes to scheduling objectives or constraints.
-- This specification grants no coding-standards waiver.
-
-## Acceptance criteria
-
-- [x] Starting Schedule Groups returns without waiting for solver completion;
-      leaving or reloading the page does not interrupt the calculation.
-- [x] Opening a show in another screen recovers its current backend status;
-      duplicate runs for the same show are prevented in frontend and backend,
-      while different shows can run concurrently.
-- [x] Running status shows elapsed time, phase and discovery of a valid solution
-      during a phase, without a fabricated completion percentage or ETA.
-- [x] SSE delivers status changes promptly through the deployed proxy. Initial
-      connection and reconnection reconcile the current state, and loss of
-      connectivity visibly marks status as potentially outdated.
-- [x] Successful runs automatically apply their result after the existing start
-      confirmation, retain stale-input protection and distinguish proven optimal
-      results from valid results at the time limit.
-- [x] The final display includes finish time and concrete attendance, spread and
-      variety results when successful; unsuccessful outcomes are distinguishable
-      and explain that previous assignments were preserved.
-- [x] An application-wide snackbar reports completion or failure with the show
-      name and View show action, including after navigation to another page.
-- [x] Connection recovery notifies once for a missed completion; phase changes,
-      repeated reconnection and reopening do not replay old snackbars.
-- [x] The latest status and outcome survive navigation, page reload and SSE
-      reconnection within the lifetime of the running backend. Durable storage
-      and recovery after backend restart are explicitly transferred to S16.
-
-## Review handoff
-
-Background execution, solver progress callbacks, SSE, frontend status recovery,
-result summaries, proxy streaming configuration and application-wide completion
-notifications are implemented and verified. S12 replaces S9's synchronous request
-behavior while retaining scheduling and result-application protections.
-
-See [S12 validation](../S12-validation.md) for verification and retained standards
-signals. Durable storage and backend-restart recovery are tracked in S16 and do
-not block review of this specification under the agreed scope adjustment.
-Implementation is ready for review; final acceptance is pending.

-# S16 — Store state in persistent storage
-
-Status: IMPLEMENTED
-
-Agreed after the grill-me interview; shared understanding confirmed.
-
-## User story
-
-As a dance school maintainer, I want application data to be stored persistently,
-so that confirmed changes and saved scheduling results survive server restarts
-and application crashes.
-
-## Storage decision
-
-Use PostgreSQL with relational tables for schools, dancers, coaches, groups,
-shows and their relationships. Use Flyway to version and apply database schema
-changes. Use JPA with Hibernate ORM for application persistence; keep the mappings
-inside the repository layer so the existing domain model remains framework independent.
-
-The existing domain has shared relationships and operations on individual school
-components. Related changes must be atomic, and multiple maintainers must be able
-to work without silently overwriting each other's changes. These requirements
-favor relational storage with transactions and referential constraints.
-
-A document database was considered: a whole-school document would align with
-JSON import/export. However, the agreed requirements provide no concrete benefit
-for that approach over relational storage. The application owns a fixed domain
-model; school-defined arbitrary fields and structures are not required.
-
-JSON remains the import/export format, rather than the primary storage model.
-
-## Scope and deployment
-
-- Support multiple schools and concurrent maintainers.
-- Target one production environment with one active backend instance.
-- A separate database service and its operational management are acceptable.
-- Multiple active backend instances, distribution across servers or regions, and
-  automatic resumption of calculations are outside S16.
-- Keep the implementation within existing project architecture and coding
-  standards; this specification grants no standards waiver.
-
-## Durability and consistency
-
-- Confirm a mutation as successful only after its database transaction commits
-  durably. All confirmed domain changes and saved scheduling results survive an
-  application restart or crash.
-- Persist schools and all their maintained domain data, relationships and saved
-  planning state, rather than only a subset of the existing in-memory state.
-- Related mutations either succeed completely or leave the previous state intact.
-  This includes deleting a dancer and cleaning up memberships, deleting a group
-  and cleaning up show references, deleting a school and its children, and
-  replacing a school through import.
-- Validate imports before publishing the replacement. Preserve the current
-  import/export behavior and identity semantics.
-- Enforce valid relationships through database constraints alongside application
-  validation.
-
-## Concurrent changes and scheduling
-
-- Use one persistent revision per school for optimistic concurrency control.
-- Mutations must identify the school revision on which they are based. Check
-  that revision and commit the change and new revision atomically.
-- Reject stale mutations with a clear conflict message; do not silently overwrite
-  newer changes. The user can reload current data and decide again.
-- Changes to different components of the same school may therefore conflict.
-  Finer-grained conflict detection is outside S16.
-- Retain the scheduling input revision check: a result computed from an outdated
-  input revision must not replace current planning state.
-- After restart, calculations interrupted by the restart must be recognizably
-  interrupted, rather than remain indefinitely marked as running. They do not
-  resume automatically. Previously saved results remain available.
-
-## Persistent scheduling status (transferred from S12)
-
-The maintainer explicitly moved durable scheduling status and backend-restart
-recovery from S12 to S16 when completing S12. S12 supplies background execution,
-status snapshots, SSE and notifications within the lifetime of the backend.
-
-- Persist the latest calculation per show in PostgreSQL, including its run
-  identifier, school/show identity, start and finish timestamps, state, latest
-  phase, whether a valid solution was found, outcome explanation and final
-  attendance/spread/variety summary when available. A run history is not required.
-- Persist acceptance of a run before acknowledging its start. After restart or
-  crash, an accepted calculation must remain identifiable even if it never
-  produced a result.
-- Commit successful assignment replacement and its completed run status
-  atomically. Publish success through the status API and SSE only after the
-  transaction commits. A failed commit must not leave a successful status with
-  missing assignments, or replaced assignments with an outdated running status.
-- On startup, mark calculations left Running by the previous backend instance
-  as Interrupted before serving their recovered status. Explain that no new
-  result was applied, retain previously saved assignments and allow a new run.
-  Do not resume calculations automatically or retain their old run-slot guards.
-- Recover the latest status and outcome through S12's existing status endpoint
-  and initial/reconnection SSE snapshots. Preserve stable run identifiers so
-  reconnecting clients can deduplicate notifications; reopening the application
-  must not replay old completion snackbars.
-- Verify recovery after both graceful restart and abrupt process termination,
-  including a calculation running at termination and a completed saved result.
-
-## Database failures and schema changes
-
-- Refuse mutations while the database is unavailable and provide a clear failure
-  message. Do not acknowledge successful storage or fall back to volatile writes.
-- Connection and Flyway migration failures at startup must be clearly visible;
-  the application must not present itself as ready for normal use when required
-  database initialization has failed.
-- Maintain the database schema through versioned Flyway migrations.
-
-## Transition from in-memory storage
-
-Start with an empty database. Existing data is transferred through the current
-JSON export/import path; no separate in-memory migration mechanism is required.
-Document that existing data must be exported before stopping the old application
-for the transition, because its current state exists only in memory.
-
-## Deferred work
-
-Database backup and restore are outside S16 and will be specified separately in
-`specs/S17_database-backup-and-restore`. That specification is intentionally empty
-for now. S16 does not promise recovery after loss of the database or its volume.
-
-## Acceptance criteria
-
-- [x] PostgreSQL stores the complete maintained domain state and saved scheduling
-      results, with Flyway managing the relational schema.
-- [x] Confirmed changes remain available after both a normal restart and an
-      application crash, using the same persistent database.
-- [x] Failed related mutations and failed school replacement imports leave no
-      partial changes or dangling references.
-- [x] Two edits based on the same school revision cannot silently overwrite one
-      another: the stale edit receives a clear conflict response, and the user
-      can reload and retry.
-- [x] Scheduling results based on outdated input revisions are rejected.
-- [x] The latest accepted scheduling run, its stable identifier, timestamps,
-      progress, outcome and objective summary survive normal restart and crash
-      and are returned through the status API and SSE snapshots.
-- [x] Successful assignment replacement and completed run status commit
-      atomically; success is published only after durable commit.
-- [x] Calculations left Running become Interrupted before recovered status is
-      served; previous assignments remain, no automatic resumption occurs and a
-      new run can start. Reopening does not replay old completion snackbars.
-- [x] Database unavailability prevents successful mutation acknowledgements;
-      startup connection and migration failures are clearly reported.
-- [x] An empty database can be initialized through Flyway and populated through
-      existing JSON import, preserving import/export behavior and identities.
-- [x] Setup and transition instructions cover the database service, persistent
-      storage, connection configuration, migrations and export-before-transition.
-
-## Implementation handoff

-# S18 — Scheduling dance groups across a show
-
-Status: IMPLEMENTED
-
-As a dance school manager,
-I want OR-Tools to schedule groups and order performances using participation,
-changing-time and variety rules,
-so that the complete show is manageable for dancers and enjoyable for audiences.
-
-Refinement confirmed by the maintainer on 2026-11-03. This specification records
-the agreed design. Implementation and validation are complete and ready for review.
-See [validation evidence](../../docs/s18-validation.md) and
-[the applied scheduling rules](../../show-scheduling-rules.md).
-
-## Show scope and configuration
-
-- A show consists of dayparts and can span multiple dates, typically two days.
-  All counts below apply across the entire show, not separately per date.
-- Each show has one configurable integer `preferredDayParts`, between 1 and the number of
-  dayparts inclusive. Its default is 2, or 1 for a one-daypart show.
-- This replaces the existing configurable appearance counts per group type.
-- A show without dayparts can be stored but cannot be scheduled.
-- If reducing the number of dayparts makes `preferredDayParts` invalid, require the user to
-  correct it before scheduling again; do not silently change it.
-- Groups without dancers are excluded from scheduling and from all performance
-  counts and showcase-position requirements.
-
-## Required group appearances
-
-- Each nonempty REGULAR, SELECTION and PRE_EDUCATION group performs in exactly
-  `preferredDayParts` distinct dayparts, once within each selected daypart.
-- Each nonempty PRE_SCHOOLER group performs exactly once in the complete show,
-  regardless of `preferredDayParts`. At most two such groups are expected. They can be assigned
-  freely to dayparts; no additional placement restriction applies.
-- Each nonempty SHOW_CASE group performs exactly once in every daypart.
-- With at least two showcase groups, each daypart starts with one showcase and
-  ends with another. Additional showcases can appear anywhere between them.
-  Opening and closing groups may differ between dayparts.
-- With exactly one showcase group, it appears either first or last in each
-  daypart; the planner chooses. It does not perform twice in that daypart.
-- With no showcase groups, there is no showcase-position requirement.
-
-## Dancer participation and coaches
-
-- A dancer without a showcase membership performs in at most `preferredDayParts` distinct
-  dayparts across the complete show. This is a hard constraint.
-- A showcase participant necessarily performs in all dayparts. Their other
-  group performances may span more than `preferredDayParts` dayparts, but this is undesirable.
-- For each non-coach showcase participant, count the distinct dayparts in which
-  they perform outside showcases. Their excess is `max(0, count - preferredDayParts)`.
-  Minimize the sum of these excesses as the first optimization priority.
-- A person dancing in several groups must use the same dancer registration in
-  every group, including when accompanying preschoolers. Up to five group
-  memberships per dancer are expected.
-- Explicitly link a coach registration to the corresponding dancer registration;
-  never infer identity from matching names. Support maintaining this link.
-- Coaches are available in all dayparts and are excluded from both the hard
-  dancer limit and the excess penalty, including coaches in showcases.
-- Being assigned as a group's coach does not automatically mean performing in
-  that group. Actual performances are determined by dancer membership only.
-  Coach availability never increases a group's required appearances.
-- Dancing coaches remain subject to changing-time rules and contribute to the
-  group's average age just like other dancing members.
-
-## Changing time and feasibility
-
-- Between any two performances involving the same dancer within a daypart,
-  there must be at least two intervening performances not involving that dancer.
-- This is mandatory for everyone, including coaches and showcase participants.
-- The rule restarts at each daypart boundary. Assume enough changing time
-  between dayparts, including on the same date.
-- All hard constraints apply together, even for unusual membership combinations
-  such as a person dancing in both preschool and ordinary groups. Do not relax
-  a rule to obtain a result.
-
-## Balance and optimization priorities
-
-- Count all scheduled performances, including preschool and showcase groups.
-- The difference between the largest and smallest daypart performance counts
-  must not exceed two. This is a hard constraint.
-- Prefer a difference of zero. Preschool groups are an expected cause of
-  differences but have no special exemption or exclusive right to cause them.
-- Optimize valid schedules in this strict priority order:
-  1. Minimize the total excess for non-coach showcase participants defined above.
-  2. Minimize the difference between largest and smallest daypart counts.
-  3. Improve style and age variety between consecutive performances within
-     each daypart.
-- A lower priority must not worsen a higher priority. Showcases participate in
-  variety scoring as well.
-
-## Variety scoring
-
-- For adjacent groups, the style penalty is the number of shared styles divided
-  by the number of distinct styles in their combined style sets. No shared
-  styles gives zero penalty; two empty style sets also give zero penalty.
-- Compute dancer ages on the first date of the show. All dancers in a group,
-  including dancing coaches, contribute equally to its average age.
-- The age penalty decreases linearly from 1 for equal average ages to 0 for a
-  difference of five years; differences greater than five years also score 0.
-  Equivalently: `max(0, 1 - abs(meanAgeA - meanAgeB) / 5)`.
-- Style and age penalties have equal weight. Minimize their combined penalties
-  over adjacent performances. Empty groups have already been excluded.
-
-## Solver execution and failure
-
-- Retain a maximum solver runtime of thirty minutes.
-- Accept a feasible result without proof of optimality, provided every hard
-  constraint holds. Distinguish feasibility from proven optimality.
-- If no valid result is found, preserve the existing assignments and order.
-- Explain whether infeasibility was proven or the time limit expired without
-  a valid result; do not report a timeout as proof of infeasibility.
-- Retain existing protections against concurrent scheduling and applying stale
-  results after relevant data changes.
-
-## Manual editing and schedule lifecycle
-
-- Add UI and API support for moving performances between dayparts and changing
-  their order. Partial or temporarily invalid assignments can be saved as drafts.
-- Distinguish draft and final schedules explicitly. Display concrete violations
-  for invalid drafts; do not present them as valid final schedules.
-- Add an explicit finalization action that checks all hard rules and permits
-  finalization only when they all pass. Optimization preferences do not block it.
-- Automatically generated valid schedules also start as drafts for manager review.
-- Manual changes to a final schedule return it to draft. Changes to relevant
-  dancer memberships, coach identity links or show settings likewise invalidate
-  final status when they affect scheduling rules.
-- Treat existing schedules as drafts when introducing this lifecycle.
-- JSON import preserves assignments and order but makes imported schedules
-  drafts and validates them against the new rules.
-- JSON export remains available for drafts and finals and preserves status.
-  Import still produces a draft even when the exported status was final.
-- Include the new configuration and coach identity information in persistence
-  and school JSON round trips so scheduling semantics survive saving and import.
-
-## Documentation and validation
-
-- Provide `show-scheduling-rules.md` describing the rules applied by OR-Tools in
-  plain English, including hard constraints, exceptions, optimization priorities,
-  scoring, cross-date scope and failure behavior.
-- Validate automatic results and finalization using the same agreed rules.
-- Verification must cover ordinary, preschool and showcase appearances; coach
-  identity and exemptions; overlapping memberships; changing gaps; balance;
-  optimization priority and scoring; multi-date shows; empty groups; invalid
-  configuration; infeasible and timed-out runs; manual drafts/finalization; and
-  persistence/import/export of the new information.

-# S1 — School JSON import and export
-
-Status: implemented
-
-## User story
-
-**As** a school maintainer,
-**I want** to export and import my dance school as a JSON file,
-**so that** I can store my school configuration locally while the application does
-not offer persistent storage,
-**and so that** I retain ownership of my data.
-
-## Intent
-
-Export downloads a complete snapshot of one dance school to a local JSON file.
-Import restores that snapshot as a new school or replaces the corresponding
-existing school after explicit confirmation.
-
-## Scope
-
-### In scope
-
-- Exporting an existing school to a readable JSON file.
-- Importing a school that does not exist or no longer exists.
-- Replacing an existing school with the complete imported snapshot.
-- Preserving all configured school data and relationships, including:
-  - School details and its persistent unique key.
-  - Dancers and their details.
-  - Dance groups, types, age ranges and styles.
-  - Dancer memberships, including dancers belonging to multiple groups.
-  - Shows, dates, day parts and any existing group assignments to day parts.
-  - Coaches and any existing links between coaches and groups.
-- Full validation, an import preview, confirmation and clear error messages.
-
-Preserving existing data does not add management screens for coaches or the
-ability to assign groups to show day parts.
-
-### Out of scope
-
-- Merging an imported snapshot with an existing school.
-- Persistent server-side storage.
-
-The existing-school prompt includes a merge option, but selecting it only displays
-that merging is not yet supported. It must not change any data. Implementing merge
-behavior requires a separate specification.
-
-## Identity and file format
-
-- Every school has a persistent unique key that is included in exports and
-  preserved through imports and subsequent exports.
-- Import identifies an existing school by that key, not by its name or a
-  runtime-generated numeric ID. The key remains meaningful after a server restart.
-- A school with the same name but a different unique key is a separate school.
-- A file contains one school and all data needed to restore it without accessing
-  another school or the original server state.
-- The readable, documented JSON format includes a `formatVersion` field.
-- Users may edit the JSON manually. Edited files undergo the same validation as
-  files produced by the application.
-- Unknown fields and unsupported format versions are rejected explicitly; data
-  must not be silently ignored.
-- Relationships in the file must be unambiguous and restored correctly. Internal
-  numeric IDs need not remain identical, provided school identity and all
-  relationships are preserved without collisions with other schools.
-
-## Export flow
-
-1. The maintainer opens an existing school's management screen.
-2. The maintainer selects the JSON export option.
-3. The application downloads a JSON file containing a consistent, complete
-   snapshot of that school.
-4. Export does not change the school or any other application data.
-
-## Import flow
-
-1. The maintainer selects the JSON import option and chooses a local file.
-2. The application validates the entire file before changing any stored data.
-3. For a valid file, the application shows a preview containing the school name
-   and the numbers of dancers, dance groups and shows.
-4. If the unique school key is unknown, the maintainer confirms adding the school
-   or cancels the import.
-5. If the key already exists, the application identifies the school that would be
-   replaced and offers replace, merge or cancel:
-   - **Replace:** explicitly warn that the existing school is replaced completely.
-     After confirmation, replace all its configured data with the snapshot.
-   - **Merge:** show a message that this functionality is not yet supported and
-     leave all data unchanged.
-   - **Cancel:** leave all data unchanged.
-6. A confirmed import is committed as one operation. The application must not
-   expose a partially imported or partially replaced school.
-7. If validation or importing fails, show **"Import niet gelukt"** together with
-   the concrete cause. The user can correct the file and try again.
-
-## Validation and failure behavior
-
-- Validate JSON syntax, the supported file structure and format version, required
-  data, field values and all relationships before applying the import.
-- Reject unknown fields and references to missing objects, including a group's
-  reference to a dancer absent from the snapshot.
-- A failure must not create a partial school, partially replace an existing
-  school, or modify another school.
-- A replacement must not remove the original school until the complete
-  replacement can succeed. If it fails, the original school remains intact.
-- Error messages explain the cause specifically enough to correct the file.
-  For example: **"Import niet gelukt: groep Hiphop verwijst naar een onbekende
-  danser."**
-
-## Acceptance criteria
-
-### Export
-
-1. Each existing school offers a JSON-file export that can be downloaded and
-   stored locally.
-2. The export includes its persistent unique key, `formatVersion`, all configured
-   data listed in scope and all relationships between those objects.
-3. Exporting leaves the application data unchanged.
-4. A school with no dancers, groups or shows can be exported and imported.
-
-### Adding a school
-
-5. A valid file with an unknown school key shows the preview before any data is
-   added. Confirming creates the complete school; cancelling changes nothing.
-6. An exported school can be restored after the original school is deleted or
-   the in-memory server state is lost.
-7. An existing school with the same name but a different key is neither replaced
-   nor treated as the same school.
-
-### Replacing a school
-
-8. A valid file with an existing school key prompts the user to replace, merge or
-   cancel and clearly identifies the existing school.
-9. Confirming replacement replaces the complete configuration. Objects and
-   relationships present only in the previous configuration are not retained as
-   part of the replaced school.
-10. Other schools remain unchanged by replacement.
-11. Selecting merge displays that merging is not yet supported and changes
-    nothing. Cancelling also changes nothing.
-
-### Validation and errors
-
-12. Malformed JSON, unsupported format versions, unknown fields, missing required
-    data, invalid field values and unresolved relationships cause the entire
-    import to fail.
-13. Each failed import displays **"Import niet gelukt"** and a concrete cause.
-14. A failed new-school import adds nothing. A failed replacement preserves the
-    entire existing school. Other schools are unaffected in either case.
-15. After a failure, the user can select a corrected file and retry.
-
-### Round-trip integrity
-
-16. Exporting and importing a school preserves every configured field and
-    relationship, including a dancer's membership in multiple groups, shows and
-    their day parts, and any existing coaches or day-part group assignments.
-17. Exporting the restored school again preserves its unique school key and
-    equivalent configuration, even if internal numeric IDs changed.
-
-## Implementation handoff

-This specification records agreed behavior. Backend endpoints, the detailed JSON
-schema and frontend implementation remain implementation work; this review does
-not implement the feature.

-# S2 — ESLint for the frontend
-
-Status: IMPLEMENTED
-
-Agreed after the grill-me review; shared understanding confirmed.
-
-## User story
-
-As a frontend maintainer, I want automated lint checks during development and in
-CI, so that likely bugs and Angular/TypeScript problems are caught before changes
-are accepted or application images are published.
-
-I also want a fast local commit hook where feasible, without losing control of
-which changes are included in my commit.
-
-## Scope and boundary with S3
-
-### In scope
-
-- Install and configure compatible ESLint, TypeScript and Angular lint tooling.
-- Apply the recommended JavaScript, TypeScript and Angular rules, including
-  recommended type-aware checks for TypeScript.
-- Lint maintained frontend application code, external and inline Angular HTML
-  templates, unit tests, Playwright tests and applicable frontend configuration
-  files.
-- Fix all existing violations of the agreed rules and verify that the application
-  still builds and its tests pass.
-- Provide local check and autofix commands, mandatory pipeline enforcement,
-  editor support and documentation.
-- Introduce a staged-file commit hook only if it meets the agreed performance
-  and change-preservation requirements.
-
-### Out of scope
-
-- Additional opinionated coding conventions or stricter rule sets beyond the
-  agreed recommended baseline. These belong in S3.
-- Backend or Java CI-helper linting.
-- Linting dependencies, generated output or generated files such as
-  `package-lock.json`.
-- A new mandatory Prettier check in CI. Prettier remains the formatting tool;
-  this spec adds its local commit-hook use only when the timing budget permits.
-
-## Existing environment
-
-The reviewed frontend uses Angular 22.2.3, Angular CLI/build 22.2.4, TypeScript
-6.0.3 and Prettier 3.9.10. TypeScript strict mode and Angular strict-template
-checking are already enabled. Prettier configuration already exists.
-
-No ESLint configuration, lint command or active Git commit hook was present at
-review. The frontend package is in `agiledancers-fe/`, below the Git root.
-Implementation must account for that layout when installing repository hooks.
-
-Choose versions compatible with the installed Angular CLI and TypeScript. Use
-supported configuration for those versions rather than copying incompatible
-examples or changing framework versions merely to introduce linting.
-
-## Lint commands and rule behavior
-
-- `npm run lint`, executed from `agiledancers-fe/`, checks the entire maintained
-  frontend scope without changing files.
-- A lint error or warning causes a nonzero exit status. A successful check means
-  there are no outstanding ESLint errors or warnings.
-- `npm run lint:fix` is an explicit local command that applies supported ESLint
-  autofixes. Developers review its changes and resolve any remaining findings.
-- CI uses the checking command only and must not repair, format, stage or commit
-  source changes itself.
-- Keep formatting under the existing Prettier configuration. Do not introduce
-  conflicting ESLint formatting rules or redefine formatting conventions in S2.
-- Narrow exceptions are permitted when a rule is demonstrably unsuitable. Each
-  suppression has a concrete explanation and the smallest applicable scope.
-  Do not broadly disable rules merely to avoid investigating existing findings.
-- Start with a clean baseline: do not introduce a legacy-violation allowance,
-  warning backlog or ignored maintained files to make the initial check pass.
-- Fixes preserve application behavior; builds and tests must still pass.
-
-## Pipeline integration
-
-Every branch pipeline must run `npm run lint` immediately after frontend
-`npm ci`, before frontend tests, frontend builds and container end-to-end tests.
-
-A failed lint check fails the pipeline and prevents image publication. Its
-concrete findings must be visible in the job log and retained in the existing
-pipeline diagnostics. The local hook never replaces the full pipeline check.
-
-Integrate this into the existing Java-based pipeline orchestration. Repository
-hook installation is skipped during CI and Docker package installation.
-
-## Editor support
-
-Recommend the ESLint extension in the existing VS Code project recommendations.
-Do not require automatic fixing or formatting on save. Document how developers
-can see findings while editing and run the same check as CI.
-
-## Local commit hook
-
-### File selection and tools
-
-- Only process maintained frontend files staged for the current commit.
-- Skip frontend checks for commits without applicable staged frontend changes.
-- ESLint only checks; it does not autofix in the hook. Errors and warnings block
-  the commit if ESLint is part of the selected hook configuration.
-- Prettier may format maintained frontend TypeScript, JavaScript, HTML, CSS and
-  JSON configuration files and stage the formatting result automatically.
-- Exclude dependencies, build output and generated files such as
-  `package-lock.json`.
-- If both tools are included, format with Prettier before checking the result
-  with ESLint. Do not run modifying operations concurrently on overlapping files.
-
-### Preserve the intended commit
-
-- Support partially staged files: format the version intended for the commit
-  while preserving unrelated unstaged changes.
-- Automatically staging formatting must not include unrelated local edits or
-  change which unrelated files are committed.
-- On any hook failure, including an ESLint failure after successful formatting,
-  abort the commit and restore the original staged and unstaged state.
-- A conflict while reconciling formatting with unstaged edits also aborts the
-  commit and restores the original state.
-- Report a concrete cause when the hook fails. Do not leave partial formatter,
-  staging or temporary-state changes behind.
-- Use tooling that supports this behavior with its state-preservation protections
-  enabled; the specific hook manager/staged-file runner is an implementation
-  choice.
-
-### Three-second performance budget
-
-The budget covers the entire additional hook duration, including file selection,
-backup/state handling, tool startup, formatting/checking, restaging and cleanup.
-It is a combined budget, not three seconds per tool.
-
-Measure the actual complete hook on the existing development mini-PC for:
-
-1. A single applicable staged frontend file.
-2. A mixed commit containing applicable frontend file types.
-3. All maintained frontend files staged together.
-
-Use a newly started process and no tool cache for each measured execution,
-including cold tool starts. Every measured execution must finish within three
-seconds. Record the machine/environment, exact staged scope, commands and timing
-results in the implementation evidence. Do not claim the budget based only on
-warm cached executions or timings of an individual tool.
-
-Choose the hook configuration from those measurements:
-
-1. Include Prettier and ESLint if the combined complete hook meets the budget.
-2. Otherwise omit ESLint from the hook and measure the complete Prettier-only
-   hook against the same budget and scenarios.
-3. If Prettier-only also fails the budget, do not install an active commit hook.
-
-Do not enforce the budget by killing a writing formatter mid-operation. It is an
-acceptance criterion for selecting the hook configuration, not a hard runtime
-interrupt that risks incomplete changes. The full type-aware ESLint check remains
-mandatory in CI regardless of the selected local hook configuration.
-
-### Installation and operation
-
-If a hook configuration meets the budget, set it up automatically during local
-`npm ci`. Skip installation in CI and Docker builds. Document the selected tools,
-installation behavior and how a developer can disable the local hook.
-
-If no hook configuration meets the budget, document that result and its timing
-evidence. Local lint commands and mandatory pipeline enforcement still apply.
-
-## Documentation
-
-Add an explanation to the root `README.md` for both `npm run lint` and
-`npm run lint:fix`, including:
-
-- Run the commands from `agiledancers-fe/`.
-- What each command checks or changes and the difference between checking and
-  autofixing.
-- That errors and warnings fail the checking command, and autofix may leave
-  findings requiring manual changes.
-- That the pipeline runs the check and blocks publication on failure.
-- The selected hook behavior, its measured performance and any omitted checks.
-- Automatic local installation, exclusion from CI/Docker installation, and local
-  opt-out instructions if a hook is installed.
-- Prettier formatting/restaging and preservation of partially staged files,
-  including restoration on hook failure, when applicable.
-
-The frontend README may link to the root explanation to keep instructions
-consistent. Record the performance evidence with the implementation documentation.
-
-## Acceptance criteria
-
-- [x] Compatible tooling checks maintained application TypeScript/JavaScript,
-      Angular templates, unit tests, Playwright tests and applicable frontend
-      configuration using the agreed recommended and type-aware rules.
-- [x] All existing violations are fixed; there is no legacy baseline allowance.
-      Frontend builds, unit tests and container end-to-end tests still pass.
-- [x] `npm run lint` checks the full scope without modifications and fails on
-      either errors or warnings.
-- [x] `npm run lint:fix` offers explicit local autofixes; CI does not modify source.
-- [x] Formatting remains under Prettier, without conflicting ESLint rules.
-- [x] Any necessary rule suppressions are narrow and concretely justified.
-- [x] Every branch pipeline runs lint immediately after frontend `npm ci` and
-      before frontend tests/builds and container E2E; lint failure prevents
-      publication and leaves actionable diagnostic output.
-- [x] VS Code recommends ESLint without mandatory fix/format-on-save settings.
-- [x] Complete-hook measurements cover the agreed single-file, mixed-file and
-      all-maintained-files cases with fresh processes and no tool cache.
-- [x] The measured three-second budget determines combined tools, Prettier-only
-      or no active hook; no writing formatter is forcibly interrupted to meet it.
-- [x] If installed, the hook processes only applicable staged frontend files,
-      applies Prettier formatting before any ESLint check, and preserves unrelated
-      files and unstaged edits, including partially staged files.
-- [x] A failed installed hook restores the original staged and unstaged state and
-      blocks the commit with a concrete explanation.
-- [x] Hook installation is automatic for local `npm ci` when applicable, skipped
-      in CI/Docker, and has documented local opt-out instructions.
-- [x] Root `README.md` explains `npm run lint`, `npm run lint:fix`, CI enforcement
-      and the selected hook behavior; measurement evidence is included.
-
-## Implementation handoff
-
-The agreed behavior has been implemented and is ready for review. See the
-implementation evidence below.
-
-## Implementation evidence
-
-Implemented with ESLint flat configuration, type-aware TypeScript and Angular
-template checks. The measured three-second budget selects a Prettier-only
-Husky/lint-staged hook; ESLint remains mandatory in the Java-based pipeline.
-See [validation and timings](../../docs/s2-validation.md) for scope, preservation
-checks, local installation and successful builds/unit/container E2E tests.

-# S4 — Build and publish pipelines in Gitea
-
-Status: IMPLEMENTED
-
-Agreed after the grill-me review; shared understanding confirmed.
-
-## User story
-
-As a maintainer, I want every branch push to build and test the application,
-so that broken changes are detected and successful main-branch builds provide
-identifiable Docker images in our own registry.
-
-## Agreed environment and feasibility
-
-- Gitea and its container registry run on the existing Synology.
-- The existing development mini-PC runs the Gitea Actions runner, separately from
-  Gitea. No additional hardware is available or required.
-- Gitea supports push-triggered Actions workflows and a runner on a separate
-  machine. Codex can implement the repository configuration and assist with the
-  installation and configuration required on the existing machines.
-- Gitea was inspected as version 1.25.4. Match the runner and workflow setup to
-  the installed version rather than assuming newer documentation applies.
-- The mini-PC was inspected as Linux x86_64 with a Docker client installed, but
-  without a reachable Docker daemon. Configuring a working daemon is part of S4.
-- The current internal Gitea/registry endpoint is `http://192.168.2.28:3000`.
-  Use that endpoint over the trusted internal network and explicitly configure
-  Docker clients that need registry access to trust this particular HTTP registry.
-  Introducing HTTPS is outside S4.
-- The runner and job containers need access to Gitea, the registry and dependency
-  download sources. The runner connects to Gitea; it needs no public incoming port.
-- The mini-PC must be on, awake and running the runner. Jobs wait while it is
-  unavailable; S4 does not promise unattended availability when the PC is off.
-
-References:
-
-- [Gitea 1.25 Actions quickstart](https://docs.gitea.com/1.25/usage/actions/quickstart/)
-- [Gitea 1.25 Actions design](https://docs.gitea.com/1.25/usage/actions/design/)
-- [Gitea container registry](https://docs.gitea.com/usage/packages/container/)
-
-## Scope
-
-### In scope
-
-- Version-controlled Gitea Actions workflows and supporting build configuration.
-- Enable Actions as needed at instance and repository level, configure Docker on
-  the mini-PC, and install, register and configure its runner.
-- Build and test both backend and frontend for every push to every branch,
-  including newly created branches, except when the author intentionally uses a
-  supported skip marker such as `[skip ci]`. Separate tag and pull-request event workflows
-  are not required; branch pushes also check changes used in pull requests.
-- Build two runnable Docker images: backend and frontend.
-- Run end-to-end tests against those built containers before publication.
-- Publish both images only from successful builds of the `main` branch to the
-  container registry on the Synology.
-- Configure registry authentication and the necessary secrets outside Git.
-- Preserve failure diagnostics and document operation and recovery.
-- Demonstrate a real successful pipeline and images that can be pulled back.
-
-### Out of scope
-
-- Automatic deployment, starting application containers on the Synology, and OTAP.
-  Starting temporary containers for pipeline tests is in scope.
-- New linting or static-analysis gates, such as ESLint or Sonar. Existing tests,
-  including architecture tests, remain mandatory.
-- Merge or release policies, separate tag/release workflows, and automatic image
-  deletion or retention cleanup. Published images remain available for now.
-- Multi-architecture images, HTTPS setup, new hardware or provisioning additional
-  infrastructure.
-
-## Build and verification behavior
-
-1. Every ordinary branch push runs backend and frontend builds and their existing
-   tests. Explicit Gitea-supported skip markers are an accepted maintainer-approved
-   opt-out.
-2. Backend verification includes the existing unit, integration/system and
-   architecture tests. Current entry point: `mvn clean verify` using Java 25.
-3. Frontend verification uses the lockfile (`npm ci`), unit tests (`npm test`) and
-   production build (`npm run build`) with a supported Node version.
-4. Build both Docker images on every branch, including branches that cannot
-   publish. The current Dockerfile only covers the backend; frontend packaging
-   must be added as part of implementation.
-5. The frontend image serves the production Angular build, supports direct SPA
-   route navigation, and forwards `/api` requests to the backend container.
-   Container addressing/configuration is an implementation choice.
-6. Run the existing Playwright end-to-end suite with Chromium against the built
-   frontend/backend containers, through the frontend's API forwarding. Adapt the
-   existing development-server test configuration as necessary: the acceptance
-   run must exercise the actual images, not development servers.
-7. Determine the intended server's CPU architecture during implementation. Build
-   for that single target architecture and run the end-to-end tests on that same
-   architecture. Do not infer the Synology's architecture from the mini-PC.
-   Any architecture mismatch must be resolved and tested on the existing hardware
-   before claiming acceptance.
-8. A failed build or test fails the pipeline and prevents publication. Test
-   containers are temporary and are cleaned up after the run, including failure.
-
-## Publication and image identity
-
-- Publish separate backend and frontend images under the repository owner's
-  namespace in the existing Gitea container registry. Document the exact names.
-- Feature branches must not publish application images.
-- Both images from a main-branch commit use the full Git commit SHA as their tag.
-  This identifies the matching pair independently of moving tags.
-- Once both commit images have been successfully published, reruns verify/reuse
-  them without overwriting either commit tag.
-- Publication succeeds only when both images are published and can be pulled
-  back from the registry. A partial publication fails the pipeline; one image may
-  already exist. A rerun preserves that image and may publish the missing image.
-- After both commit images are available, update the moving `main` tags only if
-  the commit is still the current main-branch head. Serialize/coordinate that
-  operation so an older, slower pipeline cannot move `main` backwards.
-- The two moving tags are not an atomic pair. Use the same commit SHA on both
-  images when an exact matching pair is needed. A failure updating a moving tag
-  must be visible as a pipeline failure and recoverable through a rerun.
-- No automatic deletion of published images is introduced in S4.
-
-## Failure diagnostics and operation
-
-- Failed pipelines retain available test reports, container logs, and Playwright
-  traces and screenshots for fourteen days. Collect available diagnostics even
-  when a preceding step fails; do not hide the original failure.
-- Provide a short management guide covering:
-  - Docker/runner installation, registration, startup and required access.
-  - Gitea instance/repository Actions settings and registry configuration.
-  - Required credentials, permissions and secret names, without secret values.
-  - Which settings exist outside Git and how to reproduce them.
-  - Trigger behavior, mini-PC availability and queued jobs.
-  - Image names, tags and commands to pull a matching image pair.
-  - Finding diagnostics, rerunning failed jobs and completing partial publication.
-  - The target architecture and how it was established.
-- Keep registry credentials and registration tokens out of repository files and
-  logs; use the relevant secret settings.
-
-## Acceptance criteria
-
-- [x] A push to any branch, including a new branch, starts a pipeline, except for
-      an explicit supported skip marker chosen by the author.
-- [x] Backend and frontend build and all existing tests, including architecture
-      and Playwright end-to-end tests, pass before publication is permitted.
-- [x] Every branch builds both Docker images; end-to-end tests exercise those
-      images through the frontend and its `/api` forwarding.
-- [x] A failing build or test fails the pipeline without publishing images.
-- [x] A successful feature-branch pipeline publishes no application images.
-- [x] A successful `main` pipeline publishes both images to the Synology registry
-      with the full commit SHA; both images can be pulled back.
-- [x] Published commit images are preserved on rerun; partial publication can be
-      completed without overwriting an existing commit image.
-- [x] Moving `main` tags are updated only after both commit images are available,
-      and an older pipeline cannot move them backwards.
-- [x] Publication or pull-verification failure makes the pipeline fail, even if
-      some images have already been uploaded.
-- [x] Available failure diagnostics are retained for fourteen days, and temporary
-      test containers are cleaned up on success and failure.
-- [x] The runner operates on the existing mini-PC, with Gitea and the registry on
-      the existing Synology; no additional hardware is needed.
-- [x] The single target architecture is established and the images are tested on
-      that architecture using the existing hardware.
-- [x] A management guide records setup, external settings, secrets, image usage
-      and recovery, including the need to keep the mini-PC/runner available.
-- [x] Actual pipeline runs demonstrate successful main-branch publication,
-      feature-branch checks without publication, and failure blocking publication.
-
-## Implementation handoff
-
-This specification captures the agreed design. It does not install the runner,
-change server settings or implement the pipeline. S4 is complete only when the
-configuration, documentation and operational acceptance evidence are delivered;
-workflow files alone are insufficient.
-
-
-## Implementation progress
-
-Repository implementation and local Docker verification are available. See
-[management instructions](../../docs/gitea-ci.md) and
-[validation evidence](../../docs/s4-validation.md).
-
-Backend verification (20 tests), frontend verification (14 tests), both runtime
-image builds and both Playwright tests against the containers passed. Fifteen
-Java CI publication/configuration tests pass. The runner binary and user-service
-configuration are installed on the mini-PC.
-
-The maintainer confirmed the Synology as `x86_64` / `linux/amd64`. Gitea secrets
-and the target-platform variable are configured; the runner is registered and
-online. Registry login succeeded. Real feature runs #1 and #3 passed, including
-container E2E; deliberate failure run #2 blocked the build/publication path and
-provided downloadable diagnostics.
-
-PR #1 was subsequently merged by the maintainer. Main run #7 succeeded for
-commit `2356a31aa612c8b0ce4b386a0a65da6589e23285`, publishing and pulling both
-full-SHA images and both main aliases. Registry digests are recorded in the
-validation evidence.
-
-The final real-registry probes confirmed partial-publication recovery, immutable
-commit-tag preservation on rerun and stale-main protection in isolated validation
-repositories. Application manifests remained unchanged. The maintainer confirmed
-that the Synology app.ini has no actions section, so Gitea 1.25.4's documented
-90-day artifact and 365-day log defaults apply; the workflow requests fourteen
-days for diagnostic artifacts. Explicit skip markers are accepted by the
-maintainer. All acceptance criteria are met; see the validation evidence for
-probe details, digests and the distinction from full Gitea workflow reruns.

-# S6 — Manual versioned production deployment through Gitea
-
-Status: IMPLEMENTED
-
-Agreed after the grill-me interview; shared understanding confirmed.
-
-## User story
-
-As a developer, I want to manually release a verified main-branch build from
-Gitea to the Synology, choosing a semantic version increment, so that I control
-when the launching partner receives a new production version and can recover
-the previous working version when necessary.
-
-This replaces the original automatic-deployment story. Build, test and image
-publication remain automatic; production deployment requires a deliberate action.
-
-## Existing foundation and scope
-
-- Extend the implemented S4 pipeline, which verifies builds and publishes matching
-  frontend/backend images with immutable full commit SHA tags for successful main
-  builds. Deploy those existing images without rebuilding them.
-- Target one production Docker Compose stack on the Synology (`linux/amd64`).
-  The existing Gitea runner triggers deployment over SSH.
-- Keep one active backend. A brief restart interruption is acceptable, including
-  interruption of a scheduling calculation; the user may restart the calculation.
-- Production is private to the LAN or existing VPN. A configurable Synology
-  hostname/IP and port provide access without an application login.
-- Publish only the frontend port. Keep the backend reachable within the Compose
-  network; route browser API requests through the frontend proxy.
-- Actual server addresses, ports, paths and account configuration must be
-  established and documented during implementation, without committing secrets.
-
-## Manual release interface
-
-Provide a separate **Deploy production** workflow using Gitea's native manual
-workflow trigger (`workflow_dispatch`). Its Run workflow popup offers:
-
-- **New release** or **Retry release** mode.
-- For a new release: a release-type choice of **patch**, **minor** or **major**.
-- For a retry: the existing release version tag.
-
-Provide a manual rollback action for the previous successful production release.
-The native Gitea button need not be renamed or embedded into an existing build
-run. Gitea 1.25.4 supports the required modal and choice inputs.
-
-### New release eligibility and ordering
-
-- Run the release workflow from main. Branch builds cannot deploy production.
-- Pin the current main SHA at workflow start. Require successful build checks and
-  image publication for that exact SHA; missing or failed verification leaves
-  production unchanged. Both images must be retrievable before replacement.
-- Recheck main immediately before changing production. If it has advanced, abort
-  without changing production. Once replacement starts, finish deployment or
-  recovery using the pinned SHA; later commits require another manual release.
-- Serialize deployment, recovery, rollback, version allocation and tag creation.
-  Prevent stale runs from replacing newer successful production releases.
-- Reject a new release for an already release-tagged commit and direct the
-  operator to retry or rollback instead. Repeated clicks must not create extra
-  versions or deploy out of order.
-
-## Semantic versioning and Git tags
-
-- Use one shared application version for frontend and backend, represented by
-  an immutable annotated Git tag `vMAJOR.MINOR.PATCH` on the verified SHA.
-- The first release is `v1.0.0`. Inspect remote tags before initialization and
-  fail visibly on conflicting existing history instead of overwriting it.
-- Subsequent releases increment the highest existing release version tag,
-  including tags belonging to failed deployments. A rollback does not lower the
-  version baseline. Patch increments PATCH; minor increments MINOR and resets
-  PATCH; major increments MAJOR and resets MINOR and PATCH.
-- For example, from `v1.2.3`, the choices produce `v1.2.4`, `v1.3.0` or `v2.0.0`.
-- After checking eligibility and image availability, create the tag before
-  changing production. This establishes tag-writing access before replacement.
-  Never move a release tag or reuse its version for different code.
-- Retain a tag if deployment subsequently fails or aborts. Record the outcome so
-  a tag is not mistaken for proof of successful production deployment.
-- A retry reuses the existing tag and exact SHA without allocating a version.
-  Require successful build verification and matching available images. Retrying
-  an older release must not supersede a newer successful release. Retrying an
-  existing release is an explicit exception to the current-main requirement.
-- Rollback restores an existing release and creates no new version. It is an
-  explicit exception to the prohibition on replacing newer code with older code.
-- Continue using SHA-tagged container images; the Git release tag and deployment
-  record map the semantic version to that SHA and image pair.
-- Maven/npm version fields and automated changelog generation are outside S6.
-  Do not introduce a version-bump commit and rebuild into the release path.
-
-## Deployment checks and recovery
-
-- Retrieve the candidate images and validate prerequisites before replacing the
-  running release. Frontend and backend must use the same selected commit SHA.
-- Within five minutes of starting the replacement, require all of:
-  - Backend readiness succeeds.
-  - The frontend page is served.
-  - A read-only API request succeeds through the frontend proxy.
-  - Both running containers match the selected SHA/image pair.
-- Checks must not create or modify user data. Log the selected SHA/version and
-  final outcome.
-- A failed candidate automatically restores the previous successful image pair
-  and checks its health. The workflow remains failed even if recovery succeeds.
-- Retain references to the current and previous successful releases and ensure
-  their images remain available. A manual rollback targets that previous release;
-  fail before modifying production if its required images cannot be retrieved.
-- If the first deployment fails with no previous release, or recovery itself
-  fails, stop with a clear failure report and manual recovery instructions.
-  Preserve diagnostics; do not enter an endless deployment/recovery loop.
-- Record successful production release state separately from allocated Git tags,
-  so failed attempts do not become the rollback target.
-
-## Data policy and S16/S17 boundaries
-
-S16 is **not a prerequisite** for S6. Until S16 is implemented, application state
-is held in memory and may be lost during deployment, rollback or recovery. The
-launching-partner phase explicitly accepts this limitation. Restoring old images
-does not restore lost data.
-
-- State the temporary data-loss limitation in the workflow description and
-  deployment runbook. The operator is responsible for informing the launching
-  partner; do not add a further approval step to each deployment.
-- After S16 is implemented, deployments and rollbacks must preserve saved data.
-  Keep persistent storage outside replaceable containers and do not delete it
-  during deployment or recovery.
-- After S16, ordinary release and rollback paths require database compatibility
-  with the previous application version. Incompatible migrations require a
-  separately planned maintenance procedure; image rollback cannot undo them.
-- Database backup and restore remain separate S17 work. S6 does not promise
-  recovery of data lost before persistence or through storage loss.
-
-## Credentials and operational documentation
-
-- Use a dedicated Synology deployment account with SSH key authentication and a
-  pinned server host key. Document the narrowly required deployment permissions.
-- Use a separate registry credential with pull access for production and a
-  credential with the required repository permission for release-tag creation.
-- Store deployment secrets in Gitea Actions secrets, provision server-side
-  credentials securely where needed, and keep secret values out of Git and logs.
-- Document initial provisioning, configuration, release/retry/rollback operation,
-  credential setup, health checks, release records and manual recovery.
-- Retain deployment diagnostics for fourteen days, including failed deployment
-  and recovery outcomes, without exposing credentials.
-
-## Acceptance criteria
-
-- [x] Successful main builds still automatically verify and publish matching SHA
-      images; publishing does not automatically change production.
-- [x] Gitea's manual workflow form provides new/retry mode and the appropriate
-      release-type or existing-tag inputs; invalid combinations fail clearly.
-- [x] The first release and subsequent patch/minor/major releases allocate the
-      agreed versions and immutable annotated remote Git tags on verified SHAs.
-- [x] Duplicate new releases, tag conflicts, concurrent attempts, stale main
-      snapshots and older pending deployments cannot overwrite release identity
-      or replace a newer successful release.
-- [x] An unverified release or missing image is rejected before production changes;
-      branch builds cannot deploy production.
-- [x] A real Synology deployment serves the frontend and proxied API over the
-      private endpoint, with both containers running the selected image pair.
-- [x] Readiness, frontend, proxied read-only API and image-identity checks establish
-      success within five minutes or trigger recovery.
-- [x] A deliberately failed release restores the previous successful version,
-      while the workflow reports failure. Failed first deployment and failed
-      recovery produce actionable diagnostics and manual recovery instructions.
-- [x] A failed release can be retried with its existing tag/SHA without allocating
-      another version or superseding a newer successful release.
-- [x] Manual rollback demonstrably restores the previous successful release with
-      no new version, and required retained images are available.
-- [x] The temporary pre-S16 data-loss policy is visible in workflow documentation
-      and the runbook. Once S16 applies, demonstrate saved data surviving both
-      deployment and rollback, including the migration compatibility requirement.
-      The latter is conditional S16 acceptance and is not applicable yet.
-- [x] Server setup and operational recovery documentation are usable; diagnostics
-      and release outcomes are retained for fourteen days without secrets.
-
-## Implementation and evidence
-
-This specification records the confirmed design. The evidence combines automated
-behavior tests, real Gitea production release/guard runs and isolated real NAS
-fault tests. Their distinct scopes and the virtual-tag boundary of the isolated
-tests are documented in `docs/s6-validation.md`. Configuration alone does not
-complete S6.
-
-Implementation PR #12 is merged. Production `v1.0.0` runs at
-`http://192.168.2.28:8088` following a successful main build and real manual Gitea
-deployment. Native duplicate/branch guards and downloadable artifacts were
-verified. Twelve isolated real NAS checks cover recovery, retry, distinct-version
-rollback, failure guards and manual recovery; they use separate state/containers
-and virtual test tags, without changing production. The test resources have been
-removed. See `docs/s6-validation.md` for run links, digests, evidence boundaries
-and the conditional S16 data-persistence acceptance. S6 is ready for review.

-# S8 — Palantir formatting for Java
-
-Status: IMPLEMENTED
-
-Agreed after the grill-me review; shared understanding confirmed.
-
-## User story
-
-As a developer, I want maintained Java code formatted using Palantir Java Format
-through the Maven workflow, so that local development and CI use consistent,
-reproducible formatting without unnecessary build overhead.
-
-## Scope
-
-### In scope
-
-- Backend Java production code and Java tests.
-- Maintained Java CI/source-launcher helpers under `ci/`, despite those files
-  being outside ordinary Maven source roots.
-- Integration with local Maven builds, CI checking and standalone format/check
-  commands.
-- A separate initial formatting commit, performance measurements and README
-  instructions.
-
-### Out of scope
-
-- Generated code and build output.
-- Frontend formatting, which remains under Prettier.
-- Additional coding conventions, naming rules, structural checks or refactorings.
-  Those belong in S7.
-
-## Formatter and integration
-
-- Use the **actual Palantir Java Format engine** and its Palantir style.
-- OpenRewrite is the preferred integration route. S8 includes the custom
-  Palantir adapter/recipe and bootstrap required to make that route work.
-- OpenRewrite's own `AutoFormat` is not an equivalent replacement for Palantir
-  and must not be substituted silently.
-- Spotless is not the agreed default: the maintainer has experienced unacceptable
-  slowness with it. Do not choose it merely because a native integration exists.
-- Pin the formatter, plugin and adapter dependencies to explicit versions in
-  Maven configuration. Local development and CI use the same pinned engine.
-- Formatter/integration updates are reviewed through PRs and include any resulting
-  formatting changes. Do not implicitly resolve the newest formatter at build time.
-- Include Palantir's import ordering and unused-import removal. Do not add
-  separate import policies or unrelated code transformations.
-- Leave optional extra Javadoc reformatting disabled for the initial adoption.
-
-## Maven behavior
-
-### Local builds
-
-Local builds apply formatting before compilation, so the compiled and tested
-sources are the formatted sources. Early lifecycle integration means ordinary
-`mvn compile`, `mvn test`, `mvn verify` and `mvn install` may format maintained
-Java files.
-
-Binding only to `install` does not satisfy this specification: the existing CI
-verification uses `mvn clean verify` and would not reach that phase.
-
-Provide standalone commands to:
-
-- Apply formatting without performing the complete application build.
-- Check formatting without modifying maintained sources or performing the complete
-  application build.
-
-The concrete commands/profile names are implementation work and must be documented.
-
-### CI
-
-- CI runs the check-only mode before compilation and fails if formatting differs
-  from the committed source.
-- CI must not repair or rewrite maintained Java source files automatically.
-- Use the same pinned Palantir engine, configuration and file scope locally and
-  in CI; only apply versus check behavior differs.
-- Integrate the checking invocation into the existing Java-based CI orchestration.
-- Show actionable diagnostics identifying the files that need formatting and how
-  to apply the formatter locally.
-- A formatting failure prevents successful verification and image publication.
-  Demonstrate that the check leaves maintained source files unchanged on failure.
-
-## Clean-checkout bootstrap
-
-Normal Maven commands from the repository root must work from a clean checkout
-without first requiring a developer to compile or install a custom recipe artifact
-by hand.
-
-The custom recipe/adapter must be available before it is needed to format the
-application sources. Placing it in ordinary backend source code and assuming that
-it has already been compiled is not a valid bootstrap solution.
-
-Prove bootstrap behavior with no previously installed project-specific recipe
-artifact. Normal dependency resolution is allowed; any extra tooling module or
-bootstrap must be included in the implementation and documentation.
-
-## Correctness and Java 25
-
-- Demonstrate support for every Java construct actually used in the maintained
-  backend, tests and CI helpers on the project's JDK 25.
-- Running the formatter on JDK 25 is not, by itself, proof that its parser supports
-  every possible Java 25 construct. Record relevant limitations of the chosen
-  pinned version.
-- An unprocessable file or formatter error fails the operation/build with its
-  path and a concrete cause. Do not silently skip it or exclude it merely to
-  obtain a successful build or faster measurement.
-- The adapter must preserve source paths and encoding and avoid corrupting files.
-- Formatting is deterministic and idempotent: applying it again produces no
-  further source differences. Check-only and apply mode agree on the result.
-- Application behavior remains unchanged; builds and tests must pass after the
-  initial formatting and subsequent formatter changes.
-
-## Initial adoption and commit separation
-
-Apply the chosen formatting to all existing maintained Java files in scope.
-Record this initial mass formatting in a separate **formatting-only commit**,
-without functional changes. Keep integration/configuration changes separate so
-reviewers can distinguish tooling changes from the mechanical source rewrite.
-
-Native import ordering/removal is part of that formatting commit. Do not combine
-it with unrelated cleanup or refactoring.
-
-## Performance requirements
-
-The integration must be measured rather than selected on an unverified claim that
-one wrapper is faster than another.
-
-- A repeated ordinary build with no Java-source changes may incur at most
-  **three seconds of additional formatting-related overhead**.
-- Include the required integration/recipe/bootstrap overhead in that comparison;
-  do not report only time spent inside the Palantir formatting function.
-- Compare otherwise equivalent builds with and without the formatting integration
-  under the same environment/cache conditions.
-- Also measure a build after changing a maintained Java file and a `clean verify`
-  run. Record these timings; the agreed three-second threshold specifically
-  applies to the repeated unchanged-build case.
-- Report one-time dependency downloads separately, rather than disguising ongoing
-  overhead as first-time setup or counting downloads as formatter execution.
-- Record the machine, JDK/Maven/tool versions, commands, file scope, cache state
-  and results with the implementation evidence.
-
-The time threshold is an acceptance criterion, not a hard interrupt that kills a
-formatter while it is writing source files. If the selected integration cannot
-meet the threshold, report the measurements and obtain agreement before choosing
-an alternative integration or relaxing the bound. Do not silently skip formatting,
-switch engines, choose Spotless or weaken the criterion.
-
-## README and editor integration
-
-Explain in the root `README.md`:
-
-- The formatter, pinned versions/configuration and maintained file scope.
-- The standalone apply and check commands.
-- Which local Maven lifecycle commands can rewrite files and when that occurs.
-- The CI check-only invocation and how to reproduce and resolve a failure locally.
-- Clean-checkout bootstrap behavior and any included tooling artifact/module.
-- Available supported IDE integration and how to keep its result consistent with
-  the project's pinned formatter.
-- The performance evidence and any relevant Java 25 syntax limitations.
-
-Maven is the authoritative formatting path regardless of editor. Do not require
-format-on-save or an IDE plugin. An IDE integration must not redefine the agreed
-style or silently take precedence over the Maven result.
-
-## Acceptance criteria
-
-- [x] The actual Palantir engine formats all maintained backend Java sources,
-      Java tests and `ci/*.java`; generated code is excluded.
-- [x] OpenRewrite integration, custom adapter/recipe and bootstrap are implemented
-      and reproducible from a clean checkout without manual recipe installation.
-- [x] Plugin, formatter and adapter dependencies are pinned, with matching local
-      and CI configuration.
-- [x] Local Maven builds apply formatting before compilation; `compile`, `test`,
-      `verify` and `install` reach the intended integration.
-- [x] Standalone apply and check commands work without the full application build.
-- [x] CI checks only, leaves maintained sources unchanged, reports formatting
-      differences and fails before image publication.
-- [x] Import ordering and unused-import removal follow Palantir; optional extra
-      Javadoc reformatting remains disabled and no unrelated refactoring is added.
-- [x] All currently used Java 25 syntax is handled, or causes an explicit failure
-      requiring resolution rather than silent exclusion.
-- [x] Apply/check results agree and a second apply produces no differences.
-- [x] Initial formatting is isolated in a formatting-only commit; application
-      builds and tests remain green.
-- [x] Equivalent repeated unchanged-build measurements demonstrate at most three
-      seconds of additional integration overhead. Changed-file and clean-build
-      measurements and one-time downloads are reported separately.
-- [x] Failure to meet the performance bound is reported before changing the route
-      or bound; a writing formatter is not killed to force compliance.
-- [x] README instructions cover local and CI commands, bootstrap, optional IDE
-      use, authoritative Maven formatting and verification evidence.
-
-## Implementation handoff
-
-This specification records agreed behavior. It does not install a formatter,
-create an adapter, change Maven/CI behavior or reformat source files. Recipe loading,
-Java 25 compatibility and performance must be demonstrated during implementation;
-there is no pre-existing project benchmark establishing the preferred route's
-performance.

-# S9 — Schedule dance groups across show dayparts with OR-Tools
-
-Status: IMPLEMENTED
-
-Agreed after the grill-me review; shared understanding confirmed.
-
-## User story
-
-As a dance-school maintainer, I want to assign my school's dance groups to a
-show's dated dayparts, using configurable appearance counts per group type,
-so that appearances are spread evenly across the show.
-
-## Show configuration
-
-- A show can have one to six dayparts across multiple dates. Each daypart has a
-  date and a type: MORNING, AFTERNOON or EVENING. A date/type combination must be
-  unique within a show. For example, Friday afternoon, Saturday afternoon and
-  Saturday evening are three distinct dayparts.
-- An unscheduled show may have no dayparts while being configured.
-- Daypart dates are the source of truth. Remove the separate editable show date.
-  Display the range from the earliest to the latest daypart date, or
-  "No dates configured" when there are none.
-- Each show stores an editable appearance count for every dance-group type,
-  including types with no current groups. Remove the backend
-  `DanceGroupType.dayPartsRequired` property.
-- Initialize counts when creating the show using the following defaults, where
-  N is the configured number of dayparts:
-
-  | Type | Default appearances |
-  | --- | --- |
-  | PRE_SCHOOLER | 1 |
-  | SHOW_CASE | N |
-  | PRE_EDUCATION | N |
-  | All remaining types | min(2, N) |
-
-- PRE_SCHOOLER's count is editable; one is a default, not a fixed exception.
-- Both frontend and backend enforce integer counts greater than zero and no
-  greater than N for a configured show. With one daypart, all fields display one
-  and are disabled in the frontend.
-- A show without dayparts remains unscheduled; usable counts must be initialized
-  when its initial daypart configuration becomes available.
-- Subsequent daypart edits preserve the saved counts rather than reapplying
-  defaults. Block saving if a count exceeds the new number of dayparts until
-  the user corrects it. Adding a daypart does not automatically increase counts.
-
-## Scheduling rules and objective
-
-- Use Google OR-Tools in the backend.
-- Include every current dance group belonging to the show's school.
-- Each group must appear in exactly the number of distinct dayparts configured
-  for its type. A group cannot appear twice within one daypart.
-- Among assignments satisfying those requirements, minimize the difference
-  between the largest and smallest number of group appearances per daypart.
-  Count every configured daypart, including an empty one.
-- Assign groups to dayparts only. Do not calculate performance order or timing.
-- Require at least one school group and one configured daypart. Disable the
-  scheduling action with an explanation when either is missing, and enforce
-  the same requirements in the backend.
-
-## Scheduling action and result handling
-
-- Provide an explicit "Schedule groups" action clearly indicating that it
-  replaces the current assignments. A separate preview/accept workflow is
-  outside this specification.
-- Run scheduling synchronously, with a solver time limit of 30 minutes.
-  For S9, the frontend may remain blocked until the request returns; configure
-  the request path to accommodate the agreed duration.
-- If a valid result is found, save it as a complete replacement of the existing
-  assignments. This includes a valid result whose optimality has not been proven
-  when the time limit is reached.
-- Distinguish "optimal balance" from "valid result; optimal balance not proven"
-  in the result presented to the user.
-- If validation fails, the problem is infeasible, the solver fails, or the limit
-  is reached without a valid result, explain the outcome and preserve existing
-  assignments. Never silently reduce required appearances.
-- Disable the scheduling action while a run is pending. The backend must reject
-  another concurrent run for the same show.
-- Before saving, verify that scheduling inputs have not changed during the run.
-  If they changed, reject the stale result, preserve existing assignments and
-  explain that the user must run scheduling again.
-
-## Changes affecting existing schedules
-
-- Before accepting a potentially invalidating edit, warn that an existing show
-  schedule may become invalid, name the affected shows and allow cancellation.
-- Cover adding/deleting school groups, changing a group's type, changing show
-  dayparts and changing appearance counts when affected shows have assignments.
-  Name-only edits do not require this warning.
-- After accepting the edit, do not automatically reschedule. Identify schedules
-  whose assignments no longer meet the appearance requirements and offer the
-  explicit scheduling action again.
-- Newly added groups use their type's saved count on the next scheduling run.
-
-## JSON import/export
-
-- Preserve dated dayparts, group assignments and every per-type appearance
-  setting through JSON export/import.
-- Update the format version and validation for the new structure, including
-  allowing the same daypart type on different dates.
-- No legacy export compatibility or migration is required: the application is
-  still greenfield and no exports have been made.
-
-## Optional repeatability
-
-Identical inputs producing identical assignments is a nice-to-have for
-testability, not a mandatory scheduling requirement. Spend at most three
-minutes investigating how to achieve it. Implement it only if it requires at
-most ten additional code statements; otherwise omit it. Changed inputs may
-produce different assignments regardless.
-
-## Out of scope and follow-up specifications
-
-- Group exclusions: S10_allow-group-exclusion-for-show.
-- Season context: S11_add-season-context-go-groups-and-shows.
-- Asynchronous scheduling feedback: S12_support-async-feedback-for-scheduling.
-- Scheduling on another PC: S13_create-runner-to-allow-scheduling-on-different-pc.
-- Availability restrictions, pinned assignments, capacity limits, shared-dancer
-  constraints, duration/audience balancing and performance ordering.
-
-S10–S13 are intentionally empty placeholders and are to be refined separately.
-
-## Acceptance criteria
-
-- [x] Configure up to six dated dayparts, reject duplicate date/type combinations
-      and derive the displayed show date range from them.
-- [x] Persist editable per-type counts with the agreed defaults, remove the
-      backend type-level property and validate counts in frontend and backend.
-- [x] With one daypart, every count is one and frontend fields are disabled.
-- [x] Daypart edits preserve configured counts and require correction of counts
-      that exceed the new number of dayparts.
-- [x] OR-Tools assigns every school group to exactly its type's required number
-      of distinct dayparts and minimizes the busiest/quietest appearance gap.
-- [x] Scheduling requires groups and dayparts and replaces assignments only after
-      a successful, current result.
-- [x] The synchronous request supports a 30-minute solver limit, accepts valid
-      unproven results and communicates whether optimality was proven.
-- [x] Failed, infeasible, stale and no-result runs preserve existing assignments
-      and explain why no replacement was saved.
-- [x] Duplicate concurrent runs for a show are prevented in frontend and backend.
-- [x] Potentially invalidating edits warn beforehand, identify affected shows,
-      permit cancellation and expose invalid schedules afterward without
-      automatically rescheduling.
-- [x] New-format JSON round-trips dates, assignments and all type settings;
-      legacy import support is not required.
-- [x] Any repeatability work respects both the three-minute investigation limit
-      and the ten-additional-statement implementation limit.
-
-## Implementation handoff
-
-This specification records the agreed behavior implemented on the current branch.
-The current application uses in-memory storage with JSON import/export for
-transfer. S9 adds the scheduling model, frontend controls, backend operation and
-JSON changes within that existing persistence approach.
-
-## Implementation validation
-
-- Backend: 29 tests, including real OR-Tools balancing, input validation, JSON
-  round-trips, concurrent scheduling, stale input rejection and failure preservation.
-- Frontend: 20 tests covering count validation, disabled single-daypart fields, edit cancellation,
-  API timeout contract, production build and lint checks.
-- Playwright: real REST workflow for dated dayparts, scheduling and cancellation.
-- Repeatability uses one solver-parameter statement (single worker, fixed seed);
-  no extended investigation was needed.

-Agreed after the grill-me review; shared understanding confirmed.
-
-## User story
-
-As a developer, I want a containerized Renovate bot to check the repositories on
-our Gitea server and propose dependency updates through pull requests, so that
-frontend, backend and build infrastructure dependencies remain maintainable and
-we reduce risks from outdated versions.
-
-I want external release age and project compatibility to constrain those
-proposals. I retain control over merging and can upgrade dependencies manually
-when I deliberately choose to act outside the bot's waiting period.
-
-## Environment and scope
-
-- Gitea and its container registry run on the existing Synology. Renovate runs in
-  a container on that same Synology; no additional hardware is required.
-- The established Synology target platform is `linux/amd64`.
-- Discover all repositories on this Gitea instance for which the dedicated bot
-  account has the necessary access. Support explicit repository exclusions.
-- Before dependency PRs are proposed for a newly discovered repository, create an
-  onboarding/configuration PR. A maintainer must approve and merge that
-  configuration first.
-- This project contains a `renovate.json` with its agreed compatibility and update
-  boundaries. Other onboarded repositories have their own reviewed configuration.
-- Use a dedicated bot account/token with the access required for repository
-  discovery, branches, PRs, dashboards and dependency metadata lookup. Keep
-  credential values outside Git and logs.
-
-### Dependency surfaces
-
-Cover supported maintained dependency declarations, including:
-
-- Frontend dependencies and development dependencies, compilers and test tools.
-- Backend dependencies, Maven parents/BOMs, plugins and version properties.
-- Docker base images and maintained container-image references.
-- Pinned workflow actions, including version/digest references.
-- The Renovate container's own version declaration.
-- Related lockfile changes and separate lockfile maintenance.
-
-Detection must include relevant maintained references outside ordinary manifests,
-for example the Playwright image reference in the Java CI helper. Where related
-references must match, update and validate them together. The Playwright package
-and browser image must stay aligned.
-
-One explicit manual boundary remains: the runner binary download version and its
-binary SHA-256 checksum in the CI setup helper are maintained manually. Document
-this boundary. Do not generate a partial runner update, leave an obsolete
-checksum, or confuse a Git commit SHA with the binary's SHA-256.
-
-Unsupported dependency references or missing required metadata must be visible as
-limitations/blockers, rather than silently counted as successfully managed.
-
-## Schedule and execution
-
-- Run daily at **06:00 in `Europe/Amsterdam`**. The schedule/timezone are
-  configurable and the default is recorded in the deployment configuration.
-- Provide the actual scheduler/container setup on the Synology; adding an image
-  declaration alone does not make the periodic execution operational.
-- The Synology can perform dependency checks while the development mini-PC is
-  off. Project CI jobs still depend on their existing runner availability.
-- The daily run can discover candidates, maintain eligible PRs and propose new
-  eligible updates within the agreed limits. It does not merge updates.
-
-## Seven-day release-age policy
-
-### Universal bot policy
-
-- A release must be at least **seven days old** before Renovate proposes that
-  version in a dependency PR.
-- Apply this to all bot-proposed dependency updates, including internal libraries,
-  security updates, infrastructure dependencies and the bot's own image update.
-  There is no internal-library or security-update exception.
-- Apply the same check when an existing PR is updated to a newer version. An
-  existing eligible PR must not gain an ineligible new version through refresh.
-- Missing or unreliable release timestamps block the affected proposal until its
-  age is demonstrable. Do not treat missing metadata as proof of sufficient age.
-- Show the concrete blocker in the repository dashboard, with useful diagnostics.
-  A dependent/coherent update group cannot be partially proposed in an invalid
-  combination to work around an age blocker.
-- Enforce the policy centrally across onboarded repositories. Repository-local
-  configuration, security-update defaults or bot retry/approval mechanisms must
-  not silently relax the waiting period or timestamp requirement.
-- A maintainer may choose to upgrade earlier **manually**, outside Renovate. That
-  does not authorize Renovate to bypass its policy.
-
-### Lockfiles and transitives
-
-The waiting period also applies to newly introduced or changed transitive
-versions in bot-generated lockfile changes. Determine those changes relative to
-the repository base revision used by the proposal.
-
-- Validate the age of those versions before the PR is created or updated.
-- Unknown ages block the affected proposal, just as they do for direct updates.
-- Existing unchanged versions in the base revision are not newly introduced by
-  the bot; the policy is not a requirement to rewrite all historical lock entries.
-- Additional validation is part of S5 where Renovate's native behavior cannot
-  establish this guarantee. Do not assume a package-manager cutoff covers every
-  fallback path.
-- A failing validator must actually prevent PR creation/update. A command that
-  fails but only adds an artifact error or failed status to an already-created
-  ineligible PR does not satisfy this requirement.
-
-### Metadata limitations
-
-Not every datasource/registry supplies usable release timestamps. This includes
-some container-image sources. Such updates remain blocked and visible unless
-reliable metadata support is implemented and validated; manual maintenance is
-possible outside the bot.
-
-For example, the npm release timestamp of Playwright is not proof of the release
-age of its separately published container image. Both references must satisfy
-applicable policy before their coordinated bot proposal is offered.
-
-## Compatibility and upgrade boundaries
-
-### Project-owned boundaries
-
-- The official Angular compatibility table is the reference for Angular's Node.js,
-  TypeScript and RxJS compatibility: <https://angular.dev/reference/versions>.
-- Project maintainers encode and maintain the applicable ranges in
-  `renovate.json`, including supported Node majors and TypeScript minor ranges.
-- Renovate must stay within those explicit ranges and must not independently
-  widen the policy to make a proposed version eligible.
-- Boundaries must reflect the actual installed framework/tooling metadata where
-  relevant. Remaining in the same dependency major is not sufficient if Angular
-  requires a narrower range.
-- Node.js, TypeScript and RxJS updates, including major updates, may be proposed
-  when the explicit project boundaries allow them and they remain compatible with
-  the project's Angular version.
-
-### Angular upgrades
-
-- Angular major upgrades are performed manually through a separate specification.
-- Libraries/tooling whose major numbering follows Angular are upgraded to a new
-  major with Angular, also through that manual specification.
-- Renovate proposes only minor and patch updates for Angular and that aligned
-  family, maintaining a coherent compatible combination.
-- Runtime/compiler dependencies that require matching versions stay aligned.
-  Do not assume unrelated Angular tooling repositories must all have identical
-  patch numbers merely because their majors align.
-- Group related changes where necessary to preserve compatibility. TypeScript and
-  RxJS proposals still obey their own explicit allowed ranges.
-
-### Declared versions versus installed software
-
-Maintain coherent repository declarations where a dependency appears in multiple
-places, such as Node requirements in manifests, version files, Docker definitions
-and setup checks. A bot PR does not install a new Node version on the mini-PC or
-replace a running container. Those are documented manual management actions.
-
-## Branches, PRs and limits
-
-- Use the branch prefix `renovate/`.
-- Use `renovate/major/<dependency-or-group>` for eligible major updates.
-- Use `renovate/minor-patch/<dependency-or-group>` for eligible minor/patch updates.
-- Each independent dependency has its own update PR. Related packages from one
-  upstream project may be grouped to maintain a coherent update.
-- Keep major-update proposals separate from minor/patch proposals. Necessary
-  companion changes belong with the coherent upgrade they support; unrelated
-  smaller updates are not mixed into a major PR.
-- Maintain at most **five open dependency PRs per repository**, including the
-  separate lockfile-maintenance PR when one exists.
-- Queue additional eligible updates for a later daily round after slots become
-  available. There is no dynamic sixth/seventh overflow PR or custom overflow
-  bundling requirement.
-- Onboarding/configuration PRs are outside this dependency-PR limit and precede
-  ordinary dependency proposals.
-- Renovate creates and updates proposals only. Maintainers review the change and
-  CI result and merge manually; automerge is disabled.
-
-## Lockfile maintenance
-
-- Ordinary manifest updates include the matching lockfile changes in the same
-  PR, so reproducible installation remains valid.
-- Separately maintain lockfiles within the existing manifest boundaries on a
-  branch such as `renovate/minor-patch/lockfile-maintenance`.
-- Keep that maintenance PR separate from ordinary dependency-update PRs and count
-  it within the five-PR limit.
-- Apply the same seven-day checks to newly resolved/changed versions in that PR.
-- Do not split a normal manifest update from the lockfile required by that update
-  into separately mergeable, inconsistent proposals.
-
-## Maintaining existing PRs
-
-During daily execution, Renovate may refresh existing bot proposals and rebase
-them when the base branch changes. Refreshed candidates must again pass age and
-compatibility checks.
-
-Do not overwrite manual changes on bot branches. If manual edits or conflicts
-prevent safe maintenance, preserve those edits and show that maintainer action is
-required in the dashboard.
-
-## Visibility and management
-
-- Provide a Dependency Dashboard issue per onboarded repository for pending,
-  open and blocked updates and relevant failures.
-- Explain age, missing metadata and compatibility blockers concretely.
-- Preserve execution logs and the result of each scheduled run for **thirty days**,
-  with rotation/retention configured and secret values omitted/redacted.
-- Retain operational failure information on the Synology even if startup or Gitea
-  connectivity fails before repository processing can update a dashboard.
-- Provide a management guide covering bot access and secret locations, repository
-  discovery/exclusions and onboarding, schedule/timezone, manual execution,
-  dashboards/logs, configuration validation and recovery.
-- Document project compatibility maintenance, the manual runner version/checksum
-  boundary, blocked unsupported metadata, manual host/runtime updates and applying
-  an approved Renovate-image version to the running installation.
-
-## Acceptance criteria
-
-- [ ] A working Renovate container and daily 06:00 Europe/Amsterdam schedule run
-      on the existing linux/amd64 Synology.
-- [ ] Discovery covers authorized Gitea repositories, respects exclusions and
-      requires onboarding/configuration approval before dependency proposals.
-- [ ] This project has a reviewed `renovate.json` with explicit framework and
-      dependency boundaries; compatible managed dependency surfaces are detected.
-- [ ] Direct, security and new/changed transitive lockfile versions younger than
-      seven days cannot enter new or refreshed bot PRs.
-- [ ] Unknown release ages block proposals visibly; internal dependencies do not
-      bypass the waiting period.
-- [ ] Validation proves repository overrides, security defaults and error/fallback
-      paths cannot create or update an ineligible PR.
-- [ ] Node.js, TypeScript and RxJS updates stay inside the maintainer-controlled
-      Angular compatibility bounds, including any permitted major upgrades.
-- [ ] Angular and Angular-major-aligned library major upgrades are not proposed;
-      compatible minor/patch changes and coupled package/image references remain
-      coherent.
-- [ ] Independent proposals and permitted coherent groups use the agreed
-      renovate/major/... and renovate/minor-patch/... branch conventions.
-- [ ] Major proposals remain separate from unrelated minor/patch updates.
-- [ ] No more than five dependency PRs are open per repository, including lockfile
-      maintenance; remaining candidates wait rather than form overflow PRs.
-- [ ] Normal manifest PRs include matching lockfiles; separate lockfile maintenance
-      stays within manifest ranges and satisfies the same age policy.
-- [ ] Daily maintenance preserves manual branch edits and reports conflicts;
-      merging and actual host/container upgrades remain manual.
-- [ ] The runner binary version/checksum is explicitly documented as manual, with
-      no partial or incorrect automated checksum updates.
-- [ ] Dashboards expose repository-level state; thirty-day logs also expose
-      failures before repository processing without disclosing secrets.
-- [ ] Management documentation and real execution/PR evidence demonstrate the
-      operational setup and enforcement. Configuration files alone are insufficient.
-
-## Implementation handoff
-
-This specification records agreed behavior. It does not create the bot account,
-configure credentials, deploy a container, install a schedule or create PRs/issues.
-Those actions, any necessary additional age validation and the operational evidence
-are implementation work. S5 is complete only when its behavior has been proven on
-the working installation.
