Repair the line-count ratchet baseline for focused route and executor drift.
- Add FN-7050 context to the line-count guardrail comments.
- Raise only the routes.ts and executor.ts grandfathered ceilings to match current drift.
- Preserve unrelated baseline entries for separate scoped repairs.

Repair the scoped core store/type baseline drift without broadening unrelated line-count debt.
- Add the FN-7046 CI note explaining the scoped re-ratchet for store.ts and types.ts.
- Raise only the core store.ts and types.ts grandfathered ceilings to their current generated sizes.

Split the clean-room AI merger into smaller focused modules while preserving its public behavior.
- Extract prompt builders and review verdict parsing into merger-ai-prompts.
- Extract AI merge worktree lifecycle and cleanup helpers into merger-ai-worktree.
- Re-export the extracted APIs from merger-ai and cover prompt/verdict behavior with tests.
- Remove the merger-ai line-count baseline now that the file is under the guardrail.

Refresh the opt-in line-count guard so current files match the recorded baseline.
- Document why the guard remains outside the default test gate.
- Re-ratchet current line-count violations after organic growth.
- Tighten or prune stale baseline entries and grandfather two long-existing over-cap files.

App.tsx dropped from 2,729 to 1,636 lines through the module-breakup refactor
(U1-U7), now well under the 2,000-line cap. Remove its grandfathered entry
from scripts/line-count-baseline.json so the file is subject to the cap going
forward and can never regress above 2,000. Scoped change: only the App.tsx
entry is removed; every other ceiling is untouched (a full `--update` would
have re-derived the whole baseline and re-raised ceilings for unrelated
grown files, which AGENTS.md forbids).
U8 (App.tsx module-breakup plan).
Re-ratchet the opt-in line-count audit baseline so current oversized files no longer fail the ceiling check.
- Document that the pnpm test blocker premise is stale because the guard is opt-in.
- Refresh grandfathered line-count ceilings to the current merged tree.
- Add TerminalModal.tsx to the grandfathered oversized-file baseline and drop entries that no longer need it.

Refresh the line-count audit baseline to match current repository drift.
- Update the grandfathered large-file baseline counts for current source and test files.
- Document that the line-count guard is now an opt-in audit rather than a pretest blocker.

Refresh the line-count guardrail baseline so pretest accepts the current grandfathered source sizes.
- Document the FN-6849 maintenance re-ratchet in the line-count guard script.
- Regenerate the grandfathered line-count baseline for current oversized source and test files.
- Keep the guardrail active while unblocking unrelated pretest runs.

Add a pretest guard that caps new source files at 2,000 lines to stop
god-files from being born, following the existing check-no-* guard pattern.
Existing oversized files (106 of them) are grandfathered via a ratchet
baseline (scripts/line-count-baseline.json): each is pinned to its current
line count and may shrink but never grow. Files refactored under the cap
drop out of the baseline and cannot regress. Generated, lock, locale, and
.d.ts files are out of scope via the source-extension filter.
Wired into pretest and pretest:full; covered by 11 unit tests.
