chore(config): realign CLAUDE.md size guard to measured reality (280→320) + BDR-062

The session-start line-count guard warned 'density pass requis' every session since
job1 without the 275 target (BDR-031) or even the 280 threshold ever being met —
CLAUDE.md sits at 305 (319→305 at job1, never re-inflated). A gate that never goes
green is noise. BDR-062 supersedes BDR-031's 275 TARGET only (principle kept, append-
only): 305 assumed final, guard warns past a 320 margin so real regressions still
surface. Review A6 (verifier-amended MINEUR).

 - **Alternatives rejected**: only raise the version floor (BDR-060 alone) — leaves the analyzers version-contingent, and the `/seo` nested-fix design fragile; keep analyzers self-applying but require CC≥2.1.172 — works on current env but not robust and keeps the parallel-edit race; make the dispatcher apply via direct Edit everywhere (like /harden) instead of hotfixer/feater — loses the fresh-context specialist fix; kept direct-Edit only for /harden's tiny scope.
 - **Verification**: `make test` green + 4 real smokes — analyzer emits bundle + edits nothing (md5 unchanged); AUTO fix lands on disk via L1 hotfixer with no confirmation (the exact previously-broken path); GATED withheld pre-approval then applied post-accord; /onboard writes only the report, zero source files.

+## BDR-062 — supersede BDR-031's 275-line CLAUDE.md target: 305 is the assumed reality
+
+- **Date**: 2026-07-08
+- **Status**: accepted (supersedes the 275-line density TARGET of [[BDR-031]] only; BDR-031's core principle — lightening = compression, not path-scope/externalization — stands unchanged)
+- **Decision**: The global CLAUDE.md sits at 305 lines and stays there. job1's density pass took it 319→305 and no later job re-inflated it; the extraction BDR-031 called for is done. Reaching the old 275 target (or even the 280 guard threshold) now costs clarity more than it saves tokens. The `hooks/session-start.sh` guard threshold is realigned 280→320: still catches genuine regression (real bloat past 320) but stops firing a permanent "density pass requis" warning on an assumed-final 305.
+- **Why**: the review (`.audit/review-release-1.0.0.md` A6) found the guard had warned every session since job1 without the target ever being met — a self-inflicted permanent warning, not an actionable signal. A gate that never goes green trains you to ignore it. Realign to reality; keep a 15-line margin so real regressions still surface.
+- **Alternatives rejected**: (a) finish the compression 305→≤275 — the remaining lines are load-bearing constraints, not filler; further squeeze loses clarity for a marginal token gain on a solo repo. (b) leave the guard at 280 and accept the permanent warning — a permanently-red non-blocking gate is noise. (c) rewrite BDR-031 — registries are append-only; supersede the target, keep the principle.
+- **Reference**: `hooks/session-start.sh:202-211`; supersedes the 275 target in [[BDR-031]] (principle kept). Review remediation A6, 2026-07-08.
