Land the B0/M0-M5/E0-E4/P0-P3 engineering-speedup control plane, including exact Swift caching, measured engineering metrics, canonical Rust identity validation, deterministic test isolation, proof fallback/promotion, and supporting architecture splits.\n\nRelease validation and dispatch are intentionally deferred to the next release.
## Development lane / 开发通道
- Lane: `direct-to-main` bootstrap
- Base branch: `main`
- Active train: `n/a`
- Owning Agent/session: workflow coordinator
## Change / 改动
- Split authoritative CI into parallel static, contract, Rust lint/test
shards, Swift interaction, stress, overlay, bundle, and stable `Required
CI` jobs.
- Make every ready PR to `main` a complete gate while keeping task PRs
to `gd-ops/train/*` path-scoped.
- Add direct/train worktree coordination, bounded changelog fragments,
protected main/train ruleset automation, and safe same-repository squash
auto-merge.
- Let GitHub Release promote an exact successful main commit, reuse its
source proof, and create a missing release tag only after proof
validation.
- Keep local pre-push validation bounded to basic syntax, formatting,
contracts, and compilation; complete duplicate proof stays in GitHub CI.
This is the one bootstrap PR: the auto-merge workflow and required rules
do not exist on the base branch yet. After this PR passes and is merged
once, the exact `main` push must pass `Required CI`; then the
fail-closed applicator can activate both rulesets and all later ready
`gd-ops/*` PRs follow the automated path.
## Validation / 验证
- `actionlint .github/workflows/ci.yml .github/workflows/release.yml
.github/workflows/auto-merge.yml`
- `./script/validate_source_syntax.sh`
- `./script/validate_build_scripts_safety.sh --skip-source-syntax`
- Exact staged diff was reapplied to a clean detached worktree before
the final validation run.
- 28 validation-tooling tests, 40 release-distribution tests, macOS
build-contract tests, Release shell contracts, and test-isolation
validation passed.
## Risk / 风险
- No product runtime or credential access is added.
- `pull_request_target` never checks out or executes PR code and only
enables auto-merge after API verification of active PR and `Required CI`
rules.
- Full ruleset activation fails closed until the exact remote main
commit has a trusted successful GitHub Actions push run.
- Reversible repository settings are already enabled: auto-merge,
squash-only, update branch, and delete merged branches.
