Small source edits could wait behind graph construction and contract completion. This PR allows guarded text edits and whole-file writes to proceed from verified checkout source bytes when the request does not require a fresh graph. Relationship queries retain their graph-freshness checks.

Write admission preserves checkout/root/HEAD identity, accepted ancestry, source and target guards, path serialization, parse checks and mutation ownership. Whole-file writes retain their existing optional base SHA and unconditional create/overwrite behavior. Optional admission can retry one ancestry-pin race before taking ownership; the write handler is never replayed. Explicit graph requirements, overlays and unsupported source-authority cases keep their existing admission path.

Incremental indexing publishes the requested repository first and updates companion repositories asynchronously. Core indexing no longer waits for contract completion. Contract-source projections and valid extraction work are reused, obsolete semantic attempts can be cancelled, base-edge scans stay kind-selective, and symbol-search reuse retains scoring and invalidation. Structural reparses preserve value references, external calls, builtins and unresolved-reference proofs. Retired views respect active leases. Upstream main 76c080e is incorporated, including shared disk walking and origin/seed timing.

Post-commit refresh admission creates an owned completion ticket before whole-checkout capture. The coordinator performs capture and publication asynchronously; completion proves the committed bytes or deletions in the actual published sample. Supersession, shutdown and ABA protections remain enforced. This fixes the observed failure where a disk write committed but synchronous checkout capture timed out before indexing was queued.

Retired worktree routes decline optional byte admission before coordinator activation. This preserves the existing bounded view_building refusal when no coordinator exists; both MCP interfaces verify that neither checkout is written. Completion tests also require surviving edits in different files to report the same verified publication, while same-file supersession and ABA checks remain strict.

Published candidate: ae1319b. Full local acceptance passed; CI and manual review remain pending.

The exact clean default macOS ARM64 CGO binary completed the original 14-stage campaign across 29 repositories and four linked worktrees: both 30-minute workloads, eight-agent capacity, separate 16-agent overload, restart, integrity, normal shutdown and fixture/source/process preservation. The three ordinary timed lanes recorded 93,630 correct operations, five separately counted pending observations, zero failures and zero inconclusive checks. The 16-agent diagnostic retained eight server_busy worker errors: six initialization failures and two later RPC failures. Those two timed RPC failures are included in eight, not additional normal-load failures.

The ACK union retained 7,532 acknowledged writes, zero unknown deliveries, timestamp ties or missing artifacts. Ninety surviving snapshots matched; 15 were superseded by later committed deletion ACKs. All 292 restart outcomes passed, including 112 original checks and 180 source/graph checks. The reader's static manual-review label remains; a finite peer audit reviewed the concrete exceptions and found no new correctness blocker. Prepared isolation checks remain separate from the ACK reader's source/graph assertions.

Selected separate wire cohorts retain material tails:

The N310 symbols cohort reached 6,105.613 ms maximum; actual WT symbols reached 6,337.286 ms. Unrecorded actual service proves neither PRIMARY service, WT service nor fallback. The capacity write cohorts compare with historical b55 p95/p99 of 2,446.631/2,446.631 ms (actual WT) and 3,014.104/3,329.980 ms (PRIMARY requested, actual unrecorded). Small samples and separate-run host/time/case-mix differences prevent causal claims. Other unfavorable rows remain in the reports. There is no pooled or blanket latency claim, universal five-second guarantee, or current-head native recertification of all 259 operations/21 facades.

Focused normal/race checks and golangci-lint v2.13.1 passed; permanent regressions remain in CI. At 13:31 UTC on 21 October, current-head PR checks were 51 successful, four running, one queued, zero failed. Ubuntu and Windows were complete. A later main-run snapshot has 48 successful, three running, one queued and zero failed checks; MCP is now complete and only macOS indexer partitions 0/2/3/4 remain. The earlier full PR rollup is retained until independently refreshed. The interrupted 8f predecessor full run retains no acceptance credit.

A separate manual runtime is prepared and not started. Remaining readiness work is CI completion and manual acceptance, with the symbols tail disclosed. Expanded fault recovery, local-AI task-loop correctness and MCP response-state presentation remain agreed nonblocking followups. No merge, tag or release is implied.
