…Gap-3 joint-precondition coordination audit Wave-1 PB2 default-path P0 work per docs/briefs/r3-wave1-pb2-fixedpoint-gate16-r3-horizon-worker.md. No R1 Pass/Fail change to pb_self_compile_fixed_point; gate stays sequencing-held for the R3 strong horizon. - docs/r3-program-plan.md §1.8 row #16 + T-FixedPoint tracking row: link docs/audit/r3-gap3-fixed-point-precondition-coordination-2026-05-13.md - src/v3/compiler/src/bin/self_host_fixed_point.rs header: add pointer to the audit reaffirming pb_self_compile_fixed_point_strong stays unauthored - src/v3/std/verification.dag FixedPointConverges adjacent comment: same pointer Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The 3-line comment added to FixedPointConverges adjacent block shifted byte spans in committed bootstrap_generated.rs (and siblings). No authority change; refresh snapshot to satisfy --verify gate. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Non-blocking — Strengths
docs/r3-program-plan.mdThe added Gate #16 cross-links preserve the parent fixed-point brief’s single-ledger dispatch rule and do not dilute the Pure Bootstrap 0-floor target.
✅ No blocking concerns.

Wave-1 PB2 default-path P0 readiness pin per
docs/briefs/r3-wave1-pb2-fixedpoint-gate16-r3-horizon-worker.md§"Wave-1 allowed work (when any precondition is false — default)". Adds cross-links from gate #16 authorities to the 2026-05-13 Gap-3 joint-precondition coordination audit.

Per the worker brief default path: "documentation + script/readiness alignment that reduces future P3 risk without changing R1 evaluation — e.g.

Today's audit is the canonical source-of-truth read against the four joint preconditions; the existing authorities did not yet cite it.Sequencing posture (unchanged)
