The census header has been printing `of the column guards, 0 are trait-fallback branches (already converted)` while sites of exactly that shape exist. I flagged this on #2842 as a suspected classifier gap; this confirms and fixes it. ## The miss Only `cond ? trait : literal` was recognised. The other spelling — a **negative** test with the literal on the **true** branch — is what a caller writes once it hoists its resolved lanes: ```ts complete: completeLanes === undefined ? columnId === "done" : completeLanes.includes(columnId) ``` That is `github-tracking-state.ts:245-246` — a fully converted resolver whose two degraded arms were reported as unconverted debt. **The backlog read higher than the remaining work**, and a reader chasing it was sent to lines that are already correct. Second half of the miss: `completeLanes` matches no hint. Adding `Lanes` to the hint list does **not** work, and the reason is itself a prior fix — hints are word-bounded because the unbounded form once let `hold` match `threshold` and `household`. `\bLanes\b` cannot match inside `completeLanes`, where the boundary does not exist. So resolved-lane identifiers get an explicit suffix rule. ## Both guards on the new rule exist because I broke them while writing it Worth stating, because each failure ran in the **dangerous direction** — marking a *live* line "already converted", which removes a real guard from a backlog people trust: | mistake | what it excused | |---|---| | widened the shared `testsTraitData` | fed the ancestor-walking rules too, which marked `step.status === "done" \|\| step.status === "in-progress"` at `register-task-workflow-routes.ts:941` — a step-**status** comparison, not a column guard — as converted | | let the new rule walk ancestors | excused any literal inside a block governed by a negative lane test | Measured: the count went to **6 with two of them wrong** before I caught it. The rule is now immediate-parent-only with its widened identifier match local to it, and reports exactly the **2 real sites**. ## Verification - Census: **176 guards, 2 trait-fallback** (was 176 / 0). The total is unchanged — this sub-count is diagnostic and does not move the ratchet, so `--strict` exits 0 with no baseline re-record. - 5 cases in `scripts/__tests__/lifecycle-census-inverted-fallback.test.mjs`, including both negatives that pin the mistakes above plus one for the suffix rule not over-reaching (`airplanes` is not a lane test). - `pnpm lint` clean; gate green (161/487/13/71). <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Bug Fixes** * Improved lifecycle analysis accuracy for trait fallback logic, including inverted conditions, legacy fallback syntax, and null or undefined checks. * Added safeguards to avoid misclassifying complex conditions, unrelated identifiers, and nested expressions. * Improved handling of lifecycle lane and column naming patterns. * **Tests** * Expanded coverage for valid and invalid fallback scenarios, identifier boundaries, parent-expression restrictions, and property-path checks. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com>
