Summary

Fills a spec gap identified in proposal #5942: the spec did not document what happens when invariant reconciliation fails at a phase transition.

What Changed

Added a new Reconciliation failure behavior subsection to the Invariants section (§Invariant System) documenting:

  1. ReconciliationBlockedError — raised when reconciliation fails, blocking the phase transition
  2. INVARIANT_VIOLATED event — emitted on the event bus when reconciliation fails
  3. Three phase transitions where reconciliation runs: start_strategize(), execute_plan(), apply_plan()
  4. Post-correction re-reconciliation — automatic re-run via CORRECTION_APPLIED event subscription
  5. builtin/invariant-reconciliation — the built-in actor name used as fallback

Rationale

The implementation (plan_lifecycle_service.py, actor/reconciliation.py) has this behavior but it was not documented in the spec. Implementers reading the spec would not know:

  • That reconciliation runs at Execute and Apply phase starts (not just Strategize)
  • That failure blocks the phase transition
  • What event is emitted
  • The built-in actor name

Scope

  • Minor spec extension: Adds ~15 lines to the Invariants section
  • No breaking changes: Documents existing behavior
  • No interface changes: This is purely documentation

Related

  • Proposal #5942: Triggered this PR
  • PR #5614 (merged): Added docs/modules/invariant-reconciliation.md module guide

Adds a new 'Reconciliation failure behavior' subsection to the Invariants
section documenting:

- ReconciliationBlockedError blocks phase transitions when reconciliation fails
- INVARIANT_VIOLATED event emitted on the event bus
- Reconciliation runs at start of Strategize, Execute, and Apply phases
- Post-correction automatic re-reconciliation via CORRECTION_APPLIED event
- builtin/invariant-reconciliation as the fallback actor name

This fills a spec gap identified in proposal #5942 — the implementation
(plan_lifecycle_service.py, actor/reconciliation.py) has this behavior
but it was not documented in the spec.

Hi team,

Thanks for expanding the invariant reconciliation coverage in the spec — the new subsection clearly enumerates the failure surface.

Unfortunately I need to block merge until the CONTRIBUTING.md checklist is satisfied:

  1. Requirement 5: please add an explicit Closes #... reference in the PR description.
  2. Requirement 7: CHANGELOG.md needs an entry covering this spec addition.
  3. Requirement 10: assign the PR to the appropriate milestone.
  4. Requirement 12: the lone commit lacks the mandated ISSUES CLOSED: #... footer in its metadata.

All CI checks are currently green despite the known master CI instability (issue #8759). Once the above are addressed, feel free to re-request.

PR blocked by an open issue dependency. Operator must close the dep (or remove the dependency link) before the merge driver can act. Auto-cleared by merge_drive when no open deps remain.

  
auto/ci-timeout
Most recent merge cycle hit CI timeout. Driver excludes this PR while last merge_cycle row is < 30 min old; label persists thereafter as visible history.

auto/driver-down
Merge driver heartbeat stale; pipeline halted. Closed automatically on next clean tick.

  
auto/invariant-violation
Detected master commit violating the strict merge invariant. Tracked as an issue (not a PR label); kept here for label completeness.

  
auto/last-attempt-tier-0
In-cycle escalation: most recent attempt ran at the Tier 0 slot (`tier-0`). Slot's model defined in .opencode/models/tiers.yaml.

  
auto/last-attempt-tier-1
In-cycle escalation: most recent attempt ran at the Tier 1 slot (`tier-1`). Slot's model defined in .opencode/models/tiers.yaml.

  
auto/last-attempt-tier-2
In-cycle escalation: most recent attempt ran at the Tier 2 slot (`tier-2`). Slot's model defined in .opencode/models/tiers.yaml. Gated behind IMPLEMENTER_ESCALATION_TIER2_ENABLED.

  
auto/last-attempt-tier-min
In-cycle escalation: most recent attempt ran at the Tier -1 slot (`tier-min`). Slot's model defined in .opencode/models/tiers.yaml. Suffix is ``-min`` (not ``--1``) so the Forgejo UI reads naturally.

  
Automation Tracking
Tracking issues used by the AI Automation system for agents to communicate and report.

  
auto/needs-conflict-resolution
Rebase conflict needs LLM conflict-resolver.

  
auto/needs-implementer
Failing CI needs implementer attention.

  
auto/postmortem
Documenting a driver incident or rollback.

  
auto/ready-to-merge
Reviewer has APPROVED this PR and no later REQUEST_CHANGES is outstanding. The merge driver requires this label to even consider a PR for merging. Set by the reviewer worker on APPROVE; cleared on REQUEST_CHANGES.

  
auto/restart-throttled
Train repeatedly lost master-tempo races. Driver excludes via merge_cycle until cooldown elapses; label persists as visible history.

  
auto/revert
Revert PR backing out an invariant violation. Fast-tracked through the merge driver.

  
auto/sentinel
Sentinel PR duplicated from upstream into a personal fork by tools/duplicate_prs_to_fork.py for pipeline testing. Lives only in the fork; the canonical pipeline never sees it.

  
auto/stale-inactivity
No implementer activity for N days. Flagged for human review. Auto-cleared on next push to head branch.

  
auto/unstable
Repeatedly fails on current master (>= 3 ci-fail-on-rebased-sha releases in 12 h). Excluded from driver until human triage.
