Summary

• Eleven director cards duplicated the same report envelope, DONE GATE voicings, out-of-lane prohibitions, and dispatch route table; the cards now compose shared fragments from a new packages/prompt-fragments package, with per-card golden byte pins (packages/prompt-fragments/src/goldens.ts + src/agent/directors/prompt-golden.test.ts) proving every composed card is byte-identical to the previous card. The composition contract ("a fragment change is a fleet-wide prompt change") is now a guarded invariant, not prose.
• Grok's acknowledged double residual (finish bias AND tool budget) folds into one tool-discipline block — grok leaves 91 chars lighter (−22.75 tokens at chars/4); other model families byte-identical; muse/claude/astra untouched (measured wins elsewhere). DSV4's second identity authority rehomes to prompt-variance rows with a single identity header (residuals byte-identical 1860/1348 chars; the net wire adds header bytes in exchange for one authority — deliberate).
• Dispatch's ten-lane route table is generated from a shared table pinned to DIRECTOR_REGISTRY (route-drift test); size baselines re-snapshotted to measured family maxima (the old numbers were stale in both directions); the <env> top-N + count cap is pinned by tests.
• Eval honesty: a reachable live matrix (xai provider, grok-4.6 default) ran new-vs-base — NEW 3/3 pass vs BASE 2/3 (one verify-gated failure) — favorable but too small to certify the ship bar; E1/E3/E5 (halve-the-leaf, discipline-pointer, env-cap experiments) are pending implementation/eval and are documented as pending rather than claimed. One recorded intent question: the "dead surface branches" item was verified but not deleted pending authoritative plan-intent on whether SYSTEM.md-override-only branches may go.

Verification

• bun run check exit 0 (two independent runs): 9,028 pass / 0 fail across 587 files; prompt-golden 18 tests + structural 22 + route-drift 3 + grok-residual 4; tsc --noEmit clean, dead-export guard clean, build clean.
• Independent review: byte-identity independently reproduced (11/11 vs HEAD~1 incl. qa-lead; grok merge bullet-audited — 9 surviving bullets kept once, 91 chars exact; DSV4 golden bytes 1860/1348 exact); the reviewer's should-fix (missing committed byte-pin) is exactly what this branch adds.
