Release v1.1.0: sync M5 spine after array_intersect_key/diff_key/diff_assoc JIT runtimes (#12555–#12559)

[PurHur]

Context

Daily release review 2026-06-27: quick gates 2/5 red after #12039 / #12040 closed (examples smoke recovered).

php-in-php JIT landings #12555, #12557, #12559 added lib/JIT/Builtin/*Runtime.php units without spine require_once sync — same class of regression as #10367, #10542, #11565.

Roadmap: #78 user release v1.1.0 gate checklist.

Failure (2026-06-27, Docker harness)

release-readiness:   FAIL: check-selfhost-spine-coverage-sync (exit 1)
  lib/JIT/Builtin/ArrayIntersectKeyRuntime.php
release-readiness:   FAIL: north-star5-verify --fast (exit 2)
release-readiness:   FAIL: bootstrap-selfhost-vm-driver-execute-probe (exit 2)
  free(): invalid pointer

Inventory: 3383/3383 (bootstrap-inventory ✅).

Likely also missing from spine (verify with --verbose):

• lib/JIT/Builtin/ArrayDiffKeyRuntime.php (php-in-php: JIT array_diff_key — ArrayDiffKeyJitHelper PHP (#12553) #12559)
• lib/JIT/Builtin/ArrayDiffAssocRuntime.php (php-in-php: JIT array_diff_assoc — ArrayDiffAssocJitHelper PHP (#12552) #12557)
• matching ext/standard/*JitHelper.php if inventory lists them

Acceptance criteria

• php script/check-selfhost-spine-coverage-sync.php exits 0
• ./script/release-readiness.sh --json → quick bundle 5/5 green (spine, north-star5-fast, vm-driver-probe)
• After quick green: ./script/release-readiness.sh --full --json → user_release_ready: yes

Gate command

./script/docker-exec.sh -- bash -lc 'php script/check-selfhost-spine-coverage-sync.php --verbose'
./script/docker-exec.sh -- bash -lc './script/release-readiness.sh --json'
./script/docker-exec.sh -- bash -lc './script/release-readiness.sh --full --json'

Fix hint

php script/bootstrap-selfhost-next-includes.php --bundle=test/selfhost/compiler_lib_spine_smoke/main.php --limit=6

Milestone

v1.1.0 user release — blocks tag until quick + --full bundles green.

claim: worker-lane-a — batch (issues #12564)

[PurHur]

Merged via PR #12567.

Fix: merged 7 missing inventory paths into compiler_lib_spine_smoke/main.php (array_intersect_key/diff_key/diff_assoc JIT runtimes + helpers + session_commit drift) and regenerated docs/bootstrap-inventory.md.

Verification (Docker):

./script/docker-exec.sh -- bash -lc 'php script/check-selfhost-spine-coverage-sync.php --verbose'
# OK (3383/3383)

./script/docker-exec.sh -- bash -lc './script/release-readiness.sh --json'
# user_release_ready: yes — quick bundle 5/5 green

[PurHur]

claim: cursor-agent-lane-c — lane C queue empty (0 eligible issues in 1000 open); picking release blocker to unblock #1492 M5 gates.

[PurHur]

claim released: cursor-agent-lane-c — already fixed on master (spine includes + bootstrap-inventory.md in f2e6a81); release-readiness quick bundle 5/5 green.
