Summary

  • record the exact-SHA five-lane Depot candidate and identical-SHA hosted rollback
  • preserve the accepted cache-authority risk and time-bounded exception
  • define the truthful eligible-executor meaning of 100% Depot
  • report provider-separated schema-v3 results, including macOS/Windows rollback classifications and the Windows serial-matrix caveat

Validation

  • all five Depot candidate lanes and stable summaries passed
  • all five hosted rollback lanes and stable summaries passed with exact job-name graph parity
  • just ci-validate (473 tests, 7 expected skips)
  • focused CI policy suite (75 tests)
  • actionlint
  • git diff --check

Summary by CodeRabbit

  • Documentation
    • Updated CI guidance with exact-SHA Depot validation results, provider comparisons, and hosted rollback evidence.
    • Documented eligibility, capacity outcomes, and fallback behavior across Linux, macOS, Windows, Quality, and Website workflows.
    • Clarified cache-isolation safeguards, approval requirements, expiry controls, credential restrictions, and hosted fork validation.
    • Recorded remaining follow-up items, including fork-canary validation, namespace cleanup confirmation, and isolation-sentinel requirements.

Review Change Stack

📝 Walkthrough

Walkthrough

The PR adds exact-SHA Depot PR rollout evidence, updates Depot eligibility and coverage policy, records hosted rollback and capacity classifications, and synchronizes CI status documents. Fork validation and namespace purge or expiry confirmation remain pending.

Changes

Depot rollout documentation

Layer / File(s) Summary
Rollout evidence record
.omo/specs/depot-pr-rollout-evidence.md
Records canary identities, five-workflow execution, cache observations, provider comparisons, capacity classifications, hosted rollback verification, and activation restrictions.
Policy and exception updates
ci/ci.md, ci/DEPOT_PR_RISK_EXCEPTION.md
Defines eligible Depot rows and coverage exclusions. Records validation while preserving the cache-authority finding, exception scope, and expiry.
Rollout status synchronization
.agents/skills/manage-ci/references/current-inventory.md, .omo/specs/pr-ci-optimization.md, ci/DEPOT_MIGRATION.md, ci/ci.md
Reports cache-confounded Quality and Linux observations, insufficient Website samples, macOS and Windows capacity rollback, hosted fork validation requirements, and pending namespace checks.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 2d088

The rollout documentation may overstate Depot coverage by counting expected-skip jobs that have Depot labels but no allocated runner, which could mislead rollout decisions. Merge should wait for a consistent counting rule and per-lane coverage breakdown, or explicit owner acceptance of the exception.

In @.omo/specs/depot-pr-rollout-evidence.md:
- Around line 62-65: Revise the evidence summary to separate cache-confounded
execution timings from provider-comparable queue timings. Either normalize both
cohorts by cache hit/miss state or disable caching for the comparison; otherwise
remove cache mode from the comparable dimensions, retain only the queue
observations, and do not classify Quality or Linux as eligible under the
comparability rule in DEPOT_MIGRATION.md.
- Around line 13-25: Update the rollout evidence record to add an
attempt-and-lane table covering all three attempts, including each workflow run
ID, relevant job IDs, source head SHA, and protected workflow/base SHA. Preserve
the existing candidate and rollback descriptions, and explicitly identify the
protected workflow/base revision supporting the shared workflow-graph claim.

335-344: 🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Separate planned labels from allocated execution in Depot coverage.

The two expected-skip jobs have depot-* labels but no allocated runner. Define one rule in ci/ci.md: exclude these rows from both counts, or include them in the denominator with a zero Depot numerator. Apply the same rule in .omo/specs/depot-pr-rollout-evidence.md and report per-lane eligible, executed, expected-skip, and Depot counts.
