Prose in procoder

Documentation is checked, not merely written. procoder docs blocks on broken relative references and non-compiling Mermaid; procoder docs --external adds link checking and Pages health in CI.

What the docs must keep in step with

• Every command in the dispatch appears in procoder help AND in docs/commands.md. Three shipped absent from both — config, review and analyze — because the test that existed pinned the usage text against a canonical list, and a command absent from both agrees with itself. TestEveryShippedCommandIsDiscoverable reads the dispatch now.
• Every flag the binary implements is documented, and every documented flag is accepted. docs --ack — the command the gate's own blocking message tells an agent to run — was documented nowhere.
• A command's entry describes what its flags do, not just that they exist, and says what it exits when that is surprising.

The changelog

CHANGELOG.md carries its rules at the top and the suite enforces them on the newest entry, because the release job publishes that entry verbatim. In short: an italic one-sentence summary; every headline opens with Added, Fixed, Changed, Removed or Security; every entry links the PR that shipped it; every outside contributor is named AND linked, including somebody who only filed the issue. Verify a handle with gh issue view before writing it — a misattributed credit is worse than none, and procoder release checks each one against GitHub.

Specs

Every bullet under ## In scope carries an [S-n] id, and every acceptance criterion cites the id it covers. spec check refuses otherwise, and backlog seed refuses an incomplete spec. This exists because a spec once closed at fourteen of fourteen with two features never built.
