Summary

This PR documents the invariant reconciliation failure behavior that was implemented in PR #5614 but not reflected in the specification.

Changes

Adds a new "Reconciliation failure behavior" subsection to the §Invariants section (after line 19747) documenting:

  1. ReconciliationBlockedError — raised when invariant reconciliation fails at a phase transition, blocking the plan from proceeding
  2. INVARIANT_VIOLATED event — emitted on the event bus when reconciliation fails
  3. Three phase transition points — reconciliation runs at Strategize start, Execute start, and Apply start (not just Strategize as previously documented)
  4. Automatic re-reconciliation — triggered via CORRECTION_APPLIED event subscription after a correction is applied
  5. Built-in actor name — builtin/invariant-reconciliation is the registered name for the default reconciliation actor

Rationale

The current spec says reconciliation happens "during Strategize" only. The implementation (PR #5614) runs it at all three phase transitions. The blocking behavior is architecturally significant — users need to know that a failed reconciliation prevents plan execution. This is observable user-facing behavior, not an implementation detail.

Risk

Low — additive only. No existing spec content is changed or removed.

Related Issues

  • Closes #5942 — Proposal: update specification — document ReconciliationBlockedError and invariant reconciliation failure behavior at phase transitions
  • Triggered by PR #5614 (docs: add invariant-reconciliation module guide)

Adds documentation for the reconciliation failure behavior that was
implemented in PR #5614 but not reflected in the specification:

- ReconciliationBlockedError blocks phase transitions when invariants fail
- INVARIANT_VIOLATED event emitted on reconciliation failure
- Reconciliation runs at Strategize, Execute, and Apply phase starts
- CORRECTION_APPLIED event triggers automatic re-reconciliation
- builtin/invariant-reconciliation actor name documented

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-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.

auto/postmortem
Documenting a driver incident or rollback.

  
auto/ready-to-merge

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.
