/document: Documentation sweep (TDD step 8)

Bring all documentation touched by the change up to date. Commits are blocked until this step completes.

When to run

• Previous step: /review-step (review clean).
• Next step: none (the workflow ends here with branch + PR).
• Gate (exit): full sweep complete and final vp run check green. No commit until then. Then branch + PR; never push to main.

Scope: everything touched by the change

1. JSDoc on all new/changed exported functions, types, and values (created in /mock; verify present and accurate now). Self-evident exports get exactly one line; doc blocks ≤ 3 lines for typical functions; no @example unless usage isn't inferable from the signature/name; no em-dashes. Omit @type annotations; describe non-obvious parameters; annotate Effect Schemas when not self-explanatory.
2. specs.md sync: the spec must reflect final behavior. If implementation legitimately changed details (via the pause rule), the spec already says so; verify. Acceptance criteria, skip records, and edge cases must match reality.
3. docs/ pages and package READMEs: update or create when the public API surface of a package changed. docs/ follows the Diátaxis framework (tutorial/, how-to/, reference/, explanation/). Each page fits exactly one mode; the weft-docs-author agent carries the placement rules.
4. Example readme.md for every touched examples/* package. Must contain the required sections: Overview, Problem, Solution, How It Works, When to Use.

Authorship split

• Prose documentation (docs/ pages, package READMEs, example readmes, conceptual guides): spawn the weft-docs-author agent (defined in .claude/agents/weft-docs-author.md). Give it the feature's specs.md path, the changed files, and the doc targets. It grounds itself in source before writing and never documents unverified APIs.
• JSDoc + specs.md sync: done by the main thread directly (it holds the implementation context).
• Fallback: if the agent is unavailable, the main thread writes the prose docs itself following the rules in .claude/agents/weft-docs-author.md.

Procedure

1. Inventory the diff: list changed exports, packages with public-API changes, touched examples.
2. Main thread: verify/complete JSDoc; sync specs.md.
3. Spawn weft-docs-author for the prose targets from the inventory; review its output against the source (no invented APIs, no JSX-isms, required readme sections present).
4. Run vp run check: formats and lints the JSDoc and markdown. Must be green.
5. Create a branch, commit, open a PR. Never push to main.

Rules

• Documentation is a hard gate: a feature without its docs sweep is not committable.
• All prose follows the "Docs Prose Style" rules in CLAUDE.md (sentence length cap, no em-dashes, paragraph cadence, bullets over long prose lists, metaphor allowance).
• Docs must match the source: every claim verifiable, code samples follow Oxfmt conventions (tabs, double quotes) and Effect idioms, no <Component/>-style JSX in any sample.
