Add a zero-tolerance TypeDoc documentation gate

[leynos]

Summary

This branch adds a zero-tolerance TypeDoc documentation gate to
make all. TypeDoc's notDocumented validation runs over the package
entry point (src/index.ts, resolve strategy) with emit: "none"
and warnings treated as errors: every declaration in the public surface
must carry a JSDoc comment. The gate reports the qualified name of each
undocumented declaration, writes no documentation artefacts, and fails
on a single omission. CI already runs make all, so it reaches the
gate with no workflow changes.

A small preparatory commit fixes a pre-existing Oxford-spelling
violation in AGENTS.md that the shared typos base now flags.

Adoption, 2026-09-07

The branch was stale against main and has been rebased. The head
before the rebase was eb809ad0254254c2d7027b0f2de60951e231ef83; both of
@leynos's commits are preserved and the nine commits above them are new.

The branch was first rebased onto #56, which fixed a main red since
2026-08-13 and rewrote the spelling exceptions this branch also touches.
#56 merged as f6565d3 at 2026-09-07T00:05Z, and this branch is now
rebased onto that main: the diff is this work alone.

One rebase conflict was resolved. The preparatory commit widened the
local spelling policy to ignore every inline code span; #56 deliberately
replaced that with one named pattern per identifier. The user's commit is
preserved verbatim and a separate commit restores the narrower policy, so
the difference is visible in the history rather than buried in a conflict
resolution.

Validation settings

invalidLink, invalidPath, rewrittenLink and unusedMergeModuleWith
were off alongside notDocumented, so a {@link} naming a symbol that no
longer exists passed the gate. All four are now on and the tree is clean
under them.

treatWarningsAsErrors joins treatValidationWarningsAsErrors. The
latter promotes validation findings only, so TypeDoc's other warnings, an
unknown block tag among them, were reported while the run still exited 0.
That is also what settles the @file question on the entry point: @file
is unknown to TypeDoc, and a @file tag in the entry point's module
comment now exits 3.

notExported stays off. Enabling it asks for GitHubInitialStore,
SchemaFile, ExtendedSimulationStore, GitHubExtendStoreInput and the
FoundationRouter alias to join the published surface, and exporting
those five surfaces five more (GitHubSchema, GitHubActions,
GitHubSelectors, githubInitialStoreSchema, schemaDefaults), each of
which then needs documenting or tagging. The named GitHub* output types
remain the public vocabulary, as the gate's original design records. The
developers' guide now says so rather than leaving the setting unexplained.

Contract

tests/docs-gate-contract.test.ts asserts the four links by which the
gate reaches CI: the workflow builds the all goal, all requires
docs-check, docs-check runs bun run docs:check, and that script runs
TypeDoc against typedoc.json. The workflow and the Makefile are parsed
rather than searched, and the CI step is matched by the goal token its
run script builds, never by its name; the step must carry no if and no
continue-on-error.

The step and the recipe are each required to be the whole invocation, not
to contain it. A contract that certifies a command by finding it among the
commands a script runs is satisfied by if false; then <command>; fi,
whose middle line reads exactly like an unconditional invocation, and by a
trailing || true. Five mutations covering those shapes are killed; two
of them survived an earlier revision of this test. The hole was found in
leynos/wildside#485.

tests/docs-gate-behaviour.test.ts runs the gate rather than describing
it. Using the repository's own typedoc.json, with only the entry point,
the tsconfig and the project name overridden, it checks that a documented
fixture exits 0, prints nothing and leaves no emitted file, and that an
undocumented declaration, a {@link} naming a symbol that does not exist,
and an unknown block tag each exit non-zero with the matching message.
Clearing notDocumented, invalidLink or treatWarningsAsErrors fails
exactly one of those tests, so they read the repository's settings rather
than a copy.

yaml joins the dev dependencies for the workflow parse. It was already
present transitively and is pinned in bun.lock, as is typedoc@0.28.20.

Documentation

docs/developers-guide.md gains section 3.2: what the gate checks, how to
run it alone, why it depends on typecheck, why notExported is off, and
a subsection on documenting an export covering per-property blocks,
{@link} references, @internal, and the @module header the entry
point needs.

Review walkthrough

• Start with typedoc.json
  for the gate's configuration, then the
  Makefile
  and package.json
  for the wiring: docs-check sits between typecheck and lint in
  make all (after typecheck so the generated GraphQL types exist).
• The documentation itself:
  src/simulation.ts
  (the GitHubSimulatorArgs surface) and the zod schema constants under
  src/store/entities/,
  each tagged with a documented /** … @internal */ block so TypeDoc
  does not recurse into their inferred field types — the named
  GitHub* output types remain the public vocabulary.
• src/index.ts
  converts the entry header from @file (unknown to TypeDoc) to the
  @module form, preserving the description.
• tests/docs-gate-contract.test.ts
  and
  docs/developers-guide.md
  for the contract and the guide.

Validation

Run on d1f589c:

• make all (check-fmt, typecheck, docs-check, lint, test, spelling):
  exit 0, 194 tests pass, 10 snapshots. Two later local runs on a host at
  load average 27 timed out three unrelated subprocess tests against their
  five-second deadlines; each passes on its own, and CI is green on this
  head.
• make markdownlint: 24 files, 0 errors. make nixie: all diagrams
  validated.
• Gate mutation check: deleting the JSDoc line from the exported
  InitialState alias makes bun run docs:check exit 4 naming the
  symbol. Renaming the {@link simulation} target in
  GitHubSimulatorArgs to a symbol that does not exist makes it exit 4
  with "Failed to resolve link".
• Contract mutation check: eleven single-edit mutations, one per
  assertion, each fail exactly one test. Replacing make all with the
  goals it expands to; adding continue-on-error: true to the step;
  dropping docs-check from all; dropping typecheck from the
  docs-check prerequisites; replacing the docs-check recipe with
  echo; replacing the docs:check script with echo; clearing
  treatValidationWarningsAsErrors; clearing treatWarningsAsErrors;
  setting emit to docs; clearing notDocumented; removing Property
  from requiredToBeDocumented.
• A clean docs:check run emits no files and no output.

Notes

• Part of the estate-wide TypeDoc gate rollout (same shape as
  Replace docstring-coverage with a zero-tolerance TypeDoc gate df12-build#62 and Replace the docstring audit with a zero-tolerance TypeDoc gate dakar#5).
• This repository's CI does not run markdownlint, so the guide change is
  covered locally only.

Walkthrough

Add a TypeDoc documentation gate to make all. Document exported and internal declarations. Add contract and behaviour tests for the gate. Record a startup timeout investigation and set the startup test timeout to 25 seconds.

Changes

TypeDoc validation workflow

Layer / File(s)	Summary
TypeDoc configuration and documentation contract typedoc.json, src/index.ts, src/simulation.ts, src/store/entities*.ts, docs/developers-guide.md	Configure TypeDoc to validate the public entry point and document exported declarations. Add documentation for public types and internal fixture schemas.
Package and Makefile validation wiring package.json, Makefile, .github/workflows/ci.yml, docs/developers-guide.md	Add the TypeDoc script and development dependency. Run the documentation check from make all. Update the workflow and developer guide.
Documentation gate contract and behaviour tests tests/docs-gate-contract.test.ts, tests/docs-gate-behaviour.test.ts	Verify CI, Makefile, package, and TypeDoc wiring. Verify successful documentation generation and failures for undocumented exports, unresolved links, and unknown warning tags.

Startup test timeout investigation

Layer / File(s)	Summary
Startup timeout investigation and test adjustment docs/debugging/debugging-plan-2026-08-31T14-45-31Z.md, tests/startup-output.test.ts	Record the startup timeout evidence, hypotheses, falsification plans, and execution criteria. Set the TypeScript startup test timeout to 25 seconds.

Priority: ⬇️ Low — Defer the TypeDoc gate because it strengthens package quality validation without changing runtime behavior.

Change: Feature

Merge Risk: 🟡 Moderate · up to 1ee12

The documentation gate can lose failure propagation if its workflow command is later backgrounded, and the startup investigation plan can incorrectly assign a root cause from isolated evidence. These issues should be corrected before merge.

Full details: Testing (Overall)

Explanation

Strengthen the tests before merge. The behavioural tests exercise the TypeDoc binary with copied options, and the contract tests verify the workflow, Makefile, and the presence of a typedoc.json invocation. However, tests/docs-gate-contract.test.ts does not verify that the docs:check package script is exactly one unconditional, failure-propagating command. Replacing the script with typedoc --options typedoc.json || true, or wrapping that command in a false conditional, would pass the current package-script assertion while making make all pass after a documentation failure. The direct fixture tests would also still pass because they invoke the TypeDoc binary directly, not bun run docs:check. This is a plausible incorrect implementation of the changed gate wiring, so the tests do not meet the non-vacuity and behavioural-coverage requirements.

Resolution

Harden tests/docs-gate-contract.test.ts for the package script. Assert that scripts['docs:check'] parses as exactly one unconditional typedoc --options typedoc.json invocation, with no ||, conditional shell control, or ignored failure. Alternatively, add an integration test that runs the actual bun run docs:check path and proves that a failing TypeDoc invocation reaches make.

Full details: Module-Level Documentation

Explanation

The available repository inspection failed during follow-up collection. Partial inspection confirms module documentation in the changed source modules, but it does not verify the newly added test modules.

Full details: Testing (Property / Proof)

Explanation

The pull request introduces a general invariant: every public declaration reached from src/index.ts must be documented, and links and warnings must remain valid. typedoc.json applies this rule to multiple declaration kinds, but tests/docs-gate-behaviour.test.ts covers only one type alias, one variable, one missing comment, one broken link, and one unknown tag. The added tests contain no property-based test. A small fixed table does not audit the range of declaration combinations and declaration orderings covered by the gate.

Resolution

Add a bounded fast-check property test for the TypeDoc fixture behaviour. Generate valid combinations and orderings of the required public declaration kinds, with documented and intentionally undocumented variants, and assert that documented fixtures pass while removal of any required documentation fails. Keep the existing example-based tests for exact diagnostics, link failures, warning failures, and artefact suppression. No exhaustive proof is required because the pull request introduces no lemma or proof assumption.

[leynos]

@coderabbitai both failed pre-merge rows are actioned in 1cc70eb, on head e3b54f9.

Testing (Overall). The contract tests now assert entryPoints, entryPointStrategy, and the whole validation object rather than two of its six fields, so a setting removed or added without a decision fails a test. Recipe error propagation is asserted too: the Makefile parser records any - prefix on a recipe line, and the docs-check recipe must carry none, since that prefix would swallow the gate exit status before make saw it.

Testing (Unit And Behavioural). Correct, and this was the more serious of the two: a gate configured exactly as asserted and incapable of catching anything would have passed every test. tests/docs-gate-behaviour.test.ts now runs TypeDoc over a fixture entry point in a temporary directory using the repositorys own typedoc.json, overriding only the entry point, the tsconfig and the project name. Four cases: a documented fixture exits 0, prints nothing and leaves only the three files the test wrote, which is what emit: "none"claims; removing the documentation comment, pointing the{@link}at a symbol that does not exist, and adding a@file` tag each exit non-zero with the matching message.

Clearing notDocumented, invalidLink or treatWarningsAsErrors in typedoc.json each fail exactly one behavioural test, which is the evidence that these tests read the repository settings rather than a copy of them.

Gates on e3b54f9: make all exit 0 with 207 tests passing, make markdownlint 24 files 0 errors.

For best results, initiate chat on the files or code changes.

@leynos Retain the contract and behavioural checks. They cover the configuration surface and verify that the TypeDoc gate fails for the required invalid cases.

Timestamp: 2026-09-07T11:50:35.807Z
Learning: In leynos/digitalpuddle, `tests/docs-gate-contract.test.ts` must assert the complete TypeDoc `entryPoints`, `entryPointStrategy`, and `validation` configuration, plus that the `docs-check` Makefile recipe has no `-` prefix, so configuration drift and swallowed recipe failures fail the contract test. `tests/docs-gate-behaviour.test.ts` must run TypeDoc against a temporary fixture using the repository `typedoc.json` and verify a documented entry point succeeds silently without output artifacts, while missing documentation, an invalid `{link}`, and an `file` tag each fail. Tests must fail independently if `notDocumented`, `invalidLink`, or `treatWarningsAsErrors` is cleared.

Learning: For the TypeScript package entry point `src/index.ts` in leynos/digitalpuddle, use `module` instead of the repository-standard `file` module header. TypeDoc processes `src/index.ts` as the sole resolved entry point, does not recognize `file`, and requires `module` to associate the module documentation with the module rather than the first exported declaration. The TypeDoc gate treats warnings as errors.

@coderabbitai all three rows are actioned on head ed52744.

Testing (Overall), error. Correct, and the gap was exactly where you point. The workflow step and the docs-check recipe were each required to be the whole invocation, unconditional and in the foreground, but the package script was still matched loosely: any command list containing a typedoc invocation with typedoc.json among its arguments satisfied it. 3c3eecf applies the same rule to the script, which must now be a single unconditional foreground command equal to typedoc --options typedoc.json. Four mutations killed: || true appended, & appended, the options argument dropped, and the script replaced by echo.

Testing (Property / Proof), warning. Taken. ed52744 adds two bounded fast-check properties over generated entry points built from the top-level kinds in requiredToBeDocumented. A module whose declarations are all documented passes whatever kinds it contains and in whatever order; removing the comment from any one of them fails the gate and names that declaration. Four runs per property on the repositorys shared seed in tests/support/property-test-seed.ts; each run invokes TypeDoc, so the count is deliberately small and the variation is in kind, order and choice of victim rather than in volume. Clearing notDocumented` fails the undocumented property, so it reads the repository setting.

Module-Level Documentation, inconclusive. Validated by hand rather than left inconclusive. Both added test modules open with a /** @file … */ block: tests/docs-gate-contract.test.ts describes the four links of the chain it asserts, and tests/docs-gate-behaviour.test.ts explains that it runs the gate over a fixture rather than describing it. The changed source modules were already covered by your partial inspection. Note that @file is correct in these files: the gate rejects it only in src/index.ts, which is the sole entry point in the documentation tree and heads its block with @module.

Gates on ed52744: make all exit 0 with 219 tests passing, plus make markdownlint, make nixie, make build and make spelling-helper-test all clean. cs delta main reports no issue in either test module.

@leynos Good. Keep the exact-command contract for docs:check and the bounded property tests. The reported gate results cover the three addressed findings.

Learning: In `leynos/digitalpuddle` PR `#47`, `tests/docs-gate-contract.test.ts` must require `package.json` script `docs:check` to be the single unconditional foreground command `typedoc --options typedoc.json`. The contract must reject appended `|| true` or `&`, omitted options, and replacement commands. `tests/docs-gate-behaviour.test.ts` uses bounded `fast-check` properties over the declaration kinds in `requiredToBeDocumented`: fully documented generated modules pass, while removing any declaration comment fails and names that declaration. These properties use the shared seed and a small run count because each run invokes TypeDoc.

Timestamp: 2026-09-08T02:52:53.591Z
Learning: In `leynos/digitalpuddle` PR `#47`, `tests/docs-gate-contract.test.ts` uses `isSingleUnconditionalCommand()` to certify that CI runs `make all` in the foreground and propagates its failure. The recognizer must reject a lone shell background operator (`&`), including `make all &` and `make all &` followed by `wait`, because the shell can otherwise exit successfully before the documentation gate fails.

Learning: In leynos/digitalpuddle, `tests/docs-gate-contract.test.ts` must assert the complete TypeDoc `entryPoints`, `entryPointStrategy`, and `validation` configuration, plus that the `docs-check` Makefile recipe has no `-` prefix, so configuration drift and swallowed recipe failures fail the contract test. `tests/docs-gate-behaviour.test.ts` must run TypeDoc against a temporary fixture using the repository `typedoc.json` and verify a documented entry point succeeds silently without output artifacts, while missing documentation, an invalid `{link}`, and an `file` tag each fail. Tests must fail independently if `notDocumented`, `invalidLink`, or `treatWarningsAsErrors` is cleared.

Learning: For the TypeScript package entry point `src/index.ts` in leynos/digitalpuddle, use `module` instead of the repository-standard `file` module header. TypeDoc processes `src/index.ts` as the sole resolved entry point, does not recognize `file`, and requires `module` to associate the module documentation with the module rather than the first exported declaration. The TypeDoc gate treats warnings as errors.

@leynos Mark all three checks as resolved.

• Testing (Overall): Resolved. tests/docs-gate-contract.test.ts requires scripts['docs:check'] to be one unconditional foreground command. It requires the exact token list ['typedoc', '--options', 'typedoc.json']. The recognizer rejects ||, shell control flow, and a standalone &. The current package.json value is exactly typedoc --options typedoc.json.

• Testing (Property / Proof): Resolved. tests/docs-gate-behaviour.test.ts uses bounded fast-check properties and the shared propertyTestSeed. It generates non-empty combinations and orderings of variable, function, class, interface, type alias, and enum declarations. It verifies that documented modules pass. It also verifies that removing any selected declaration comment fails and reports that declaration.

• Module-Level Documentation: Resolved. tests/docs-gate-contract.test.ts and tests/docs-gate-behaviour.test.ts each start with a clear @file module docstring. The inspected changed source modules also have module-level documentation. src/index.ts correctly uses @module, as required for the TypeDoc entry point.

Do not create an AI agent prompt or a GitHub issue. No remaining work is required for these findings.

I used the stored PR guidance for the exact docs:check contract, bounded property tests, and the src/index.ts @module requirement.
