dead-words

The vocabulary backstop — a CI grep gate keeping the v0.3.0 renames' retired words (yatsu · reading · board · proof · blob · scan · reopen · rawkey · loss-signal) off every product surface; prose stays exempt.

raw source

The v0.3.0 rename cut every concept to one word (eval, graph, evidence, …). A rename that isn't guarded regresses: the next error message, route, or file casually reintroduces the old name and the one-word-one-meaning economy erodes. So the retired words are dead on product surfaces — command names, route/protocol strings, agent- and user-facing labels, file names, node dir names — while prose stays legal (spec bodies, docs, code comments, archived sidecars may narrate history under its historical names). CI enforces this permanently.

expanded spec

scripts/dead-words.mjs (a CI step beside spex spec lint in ci-gate's workflow; runnable locally, exit 0 clean / 1 findings) scans exactly the surfaces where the words are dead, not the whole repo:

• string literals in source under spec-cli/src, spec-eval/src, spec-forge/src, spec-dashboard/src, spec-cli/templates — a command, route, or label lives in a string; a code comment is prose and never scanned. A real tokenizer (comment/string/template/regex-aware) does the extraction, so a quoted word inside a comment can't false-positive and a regex body can't open a phantom string. *.test.*, __fixtures__, and *.md are exempt (test data mirrors archived or external shapes; markdown is prose).
• whole non-comment text of shell hooks under the same roots — hook scripts speak to agents at runtime, so their text is label surface, not prose.
• file and dir basenames under those roots, and node dir names under .spec — split on camelCase and separators, so BoardStats.jsx hits while Dashboard.jsx (one word) does not.

The exemption mechanism is deliberately in-place, not a central list: a line carrying dead-words-ok: <reason> is skipped, and the reason is REQUIRED — every exemption self-justifies at the occurrence. The legitimate classes are narrow: archive readers (the freshness walk's dual pathspec, the retired cache-dir recognizer — immutable history is read under its archived names), git plumbing (cat-file blob is git's noun, not ours), and one-version signposts (the unknown-command tombstones that teach the renamed spelling until 0.4.0 deletes them).

The scanner distrusts itself: every run starts with a self-check that plants a dead word in a string, one in a comment, and one in a regex, and refuses to report a clean tree (exit 2) unless exactly the string hit fires — a silently broken tokenizer must not green-wash the gate.
