Lane C status — no eligible issue

Cross-post because #10533 comments are disabled (>2500).

Automation: Worker lane C (issue % 3 == 2)

Trust probe (this workspace)

Gate	Status	Note
docker info	green	OK
php script/bootstrap-inventory.php --check	green	OK 6639/6639
make bootstrap-selfhost-vm-driver-execute-probe	green	OK /compiler/build/selfhost-lib-spine-smoke
./script/release-readiness.sh --json	green (recent master snapshot /tmp/release-ready.json)	user_release_ready: yes; gen-0 provenance stale (45d / 7290 lowering commits — known #23468 class)
Open PRs	none	gh pr list --state open empty

First failing command: none on trust probes above. Did not re-run full bootstrap-selfhost-link (VM driver probe path green).

Triage

• Scanned implementation-ready: 171 open; Lane C share 50 (n % 3 == 2).
• 0 eligible after ownership filters: all 50 carry label stdlib → PHP Compiler STD Lib (do not claim).
• language / bootstrap label lists: 0 open.
• Non-stdlib Lane C opens without claimable IR: Plan: steering php-compiler to a defensible v1.1.0 release #23474 (plan), Architecture: side-load extensions — core should not link all 75 by default #23480 (architecture), Perf: generated code is 4-14x SLOWER than Zend on basic loops and calls #23483 (perf).
• Skipped meta: prior Lane status issues, Parity backlog snapshots, Strategic alignment: compiler excellence pillars (2026 H2) #10533, Epic: Self-host critical path — compiler compiles itself (M3→M5) #1492.
• Did not claim stdlib / named-ext/ / php-in-php / runtime-shrink issues or steal from lanes A/B.

Stopping this run per worker protocol.

Correction — live release-readiness --json finished red

Earlier body cited a green master snapshot. This workspace’s live run completed with:

• user_release_ready: no
• First fail: check-helper-runtime-prelink.php --strict — core_fingerprint mismatch committed 05b48e2da9f49b5225f7 vs live c09f7a6ac368b1161c53 (Release blocker: committed helper-runtime cache is stale, so a clean checkout cannot compile hello world in 2 minutes #24302)
• Also fail: cold-build-check timeout after 120s (corpus warmup again — Release blocker: committed helper-runtime cache is stale, so a clean checkout cannot compile hello world in 2 minutes #24302 / AOT: skip the corpus warmup when the committed prelink cache is current (#24302) #24351)
• Still ok: inventory 6639/6639, spine-coverage, root-readme-sync, north-star5-fast, vm-driver-probe
• gen-0 provenance still stale (45d / 7309 lowering commits)

Pillar 1 trust is red on helper-runtime freshness / cold-build; out of Lane C claimable scope this run (stdlib-owned IR only). Helper-cache / release owners should refresh prelinked/helper-runtime per #24302.

cleanup: closing superseded lane-status noise. Canonical latest status for this lane: #25714. Not an implementation issue — workers should use open implementation-ready tickets only.
