# Fullstack + Multi-file Gap Hunt - 2026-02-26
|
||
|
|
|
||
|
|
Runs:
|
||
|
|
- Baseline AB-only: `logs/taskitem_runs/challenging_fullstack_multifile_20260226`
|
||
|
|
- Production-enabled recheck: `logs/taskitem_runs/challenging_fullstack_multifile_20260226_r5`
|
||
|
|
- Parity-gated production recheck: `logs/taskitem_runs/challenging_fullstack_multifile_20260226_r6`
|
||
|
|
- Repair-augmented parity recheck: `logs/taskitem_runs/challenging_fullstack_multifile_20260226_r7`
|
||
|
|
|
||
|
|
## High-Density Findings
|
||
|
|
|
||
|
|
- `total_runs=12`
|
||
|
|
- Path A ready: `50%`
|
||
|
|
- Path B ready: `50%`
|
||
|
|
- C++ readiness in this set: `0%` (Path A and Path B)
|
||
|
|
- Python readiness in this set: `100%`
|
||
|
|
- Token ratio `PathB/PathA`: `14.15x`
|
||
|
|
|
||
|
|
## New Gap Signals
|
||
|
|
|
||
|
|
- `GR-016` Multi-file transactional closure gap
|
||
|
|
- deterministic generation struggles when changes must span tightly-coupled file sets with rollback semantics.
|
||
|
|
|
||
|
|
- `GR-017` Full-stack contract propagation gap
|
||
|
|
- backend/frontend/schema/docs co-evolution lacks robust cross-layer consistency guarantees in deterministic path.
|
||
|
|
|
||
|
|
- `GR-018` Performance/security/rollout constrained refactor gap
|
||
|
|
- changes with explicit SLO/security/rollout constraints are under-enforced as first-class execution contracts.
|
||
|
|
|
||
|
|
## Suggested Next Sprint Tranche
|
||
|
|
|
||
|
|
- `217`: multi-file edit graph + required-artifact closure gate
|
||
|
|
- `218`: full-stack contract propagation gate (OpenAPI/sdk/frontend sync)
|
||
|
|
- `219`: migration/backfill/rollback hard gate with data-safety evidence
|
||
|
|
- `220`: security propagation + deny-by-default cross-layer gate
|
||
|
|
- `221`: SLO budget and rollout-choreography strict enforcement
|
||
|
|
|
||
|
|
## Post-217-221 Recheck (r5)
|
||
|
|
|
||
|
|
- `fullstack_contract.invalid_runs=0` with strict-mode checks enabled.
|
||
|
|
- Production loop now runs across this set (`RUN_PROD=1`) and reports:
|
||
|
|
- `ready_runs=12/12`
|
||
|
|
- `false_green_candidates=0`
|
||
|
|
- `ab_prod_divergence_count=6`
|
||
|
|
- Remaining blocker is not contract presence; it is execution-path divergence:
|
||
|
|
- C++ AB readiness remains `0%` while production reports ready for same C++ rows.
|
||
|
|
|
||
|
|
## Post-222-224 Parity Recheck (r6)
|
||
|
|
|
||
|
|
- parity mode enabled (`REQUIRE_AB_PARITY=1`)
|
||
|
|
- unresolved divergence now closed:
|
||
|
|
- `ab_prod_divergence_count=0`
|
||
|
|
- safety gate now blocks inconsistent C++ rows:
|
||
|
|
- `ab_consistency_blocked_count=6`
|
||
|
|
- practical effect:
|
||
|
|
- production ready drops from `12/12` (r5) to `6/12` (r6), matching only non-divergent rows.
|
||
|
|
|
||
|
|
## Post-225-227 Repair + Parity Recheck (r7)
|
||
|
|
|
||
|
|
- deterministic path-B repair layer enabled for C++/Go/Rust transpile artifacts.
|
||
|
|
- parity closure metrics:
|
||
|
|
- `ab_prod_divergence_count=0`
|
||
|
|
- `ab_consistency_blocked_count=0`
|
||
|
|
- hard suite headline:
|
||
|
|
- Path B ready: `12/12` (`100%`)
|
||
|
|
- production ready: `12/12` (`100%`)
