F827 — HTTP Chat Guard Branchless
F827 covers “HTTP Chat Guard Branchless”. The canonical record classifies it as failed/revert, based on 2 source artifacts and 1 original source figure. The highlighted measurements are Guard Cases Passed = 5, Pass = No, and Target Branch Before Total = 3.
Purpose and research question
F827 revisited the HTTP chat guard to reduce the remaining executable branches while preserving its classification and verification role. The benchmark asked whether the guard could become branchless without losing any of six recorded guard cases.
Method
F827 counted executable branches in the HTTP chat guard before and after the branch-reduction patch, scanned the target for remove/refactor markers, and reran six guard cases. The target fell from three branches to one and reached zero removal markers, but only 5/6 behavior cases passed.
Documentation basis
2 source artifacts and 1 phase-specific figure are recorded for this phase.
Evidence highlights
- Target branches: 3 → 1
- Target remove/refactor markers: 0
- Guard cases: 5/6
- Active-runtime if count: 441
- Decision: FIX_REQUIRED

These are original source figures from the existing public evidence set, not editorial HTML visualizations.
Result and interpretation
Branches decreased from 3 to 1 and the target remove/refactor count reached 0, but the guard suite passed only 5 of 6 cases. The phase did not pass; its explicit decision remains FIX_REQUIRED.
