Context
12-round RLCR session (5 new tasks, 8 ACs). Structured review phase (rounds 0-4) caught critical issues effectively. Code review phase (rounds 5-11) produced valid but diminishing-severity findings. Session could have safely terminated 5 rounds earlier.
Findings
F1: Two-Phase Review Mode Not Formalized
Sessions naturally divide into structured AC review → diff-based code review, but the methodology doesn't formalize this transition. Post-AC-completion rounds continued cycling on P3 findings with diminishing returns.
F2: Cascading Fixes From Single Root Cause (3 rounds)
Incorrect seeded data produced findings across 3 consecutive rounds because neither reviewer nor implementer performed a transitive search for all references to the same data.
F3: Schema Migration Not Pre-Planned
3 rounds spent on migration issues that should have been a plan-level checklist item.
Recommendations
M1: Define Hardening Phase Bound [High]
After structured review declares all ACs met, enter a hardening phase with max 3 rounds. Terminate when 2 consecutive rounds produce no P0/P1 findings.
M2: Require Transitive Fix Directives [High]
When review finds incorrect data, the directive must enumerate ALL locations where the same data appears. Fix all in one round, not piecemeal.
M3: Pre-Plan Schema Migration Requirements [Medium]
Plans that modify existing service schemas must include an explicit checklist item for idempotent migration statements.
M4: Pre-Classify Validation Activities [Medium]
Tag each validation activity as "per-round" or "pre-completion" to prevent deferring full-pipeline testing.
M5: Expand Validation Centralization Scope [Low]
When review finds a validation bypass, require auditing ALL code paths that write the same data, not just the specific path found.
M6: Lower BitLesson Extraction Threshold [Low]
Generate lessons for any fix requiring multi-file interaction understanding, even if the pattern isn't novel.
