Overview / Motivation
Auto-filed by /daily 2026-07-06 (route 2: behavior/logic change -> independent review), from the nightly transcript problem sweep.
Goal
(a) require whitespace/word-boundary around the ASCII x multiplication token and add 2 negative fixtures; (b) extend _C18_NEG_DEFER_RE with the missing negation forms and fix the dead n't alternative; tests for both.
Workflow gap
- Bug observed: Two concrete residuals parked under the recursion guard by the #1086 workflow-fix session (28d40897, 2026-07-06), with fix sketches already written: (1) the c12 ASCII 'x' multiplication token matches word-split artifacts (needs a whitespace/boundary requirement); (2) _C18_NEG_DEFER_RE misses common negations — doesn't/cannot/can't/'fails to'/until — and its n't token is dead code.
- Why it is a workflow gap: the failure originates in the workflow surface / shared helper named below, not in any one experiment.
- Confidence (emitter): medium
Scope / surfaces
- Primary target:
scripts/verify_plan.py - Grep the workflow surface for the pattern before editing and update every hit; list them in the plan.
Constraints / invariants
scripts/workflow_lint.py --check-asks+--check-referencesstay green; ruff clean on touched files; relevant tests pass.
Provenance
- workflow_fix_target: scripts/verify_plan.py
