Flip ADR-0173 Proposed -> Accepted. This is the W0 gate for the
workbench-UI ratification wave: it amends ADR-0160's read-only stance
narrowly to admit operator-driven invocation of the three existing,
replay-gated Tier 1.5 handlers (apply_lexical_claim, apply_frame_claim,
apply_composition_claim) as a local keyboard accelerator over ADR-0161
Surface C. No UI code; implementation remains gated to the W1..W4
acceptance gates in the ADR.
Also lands the reconciled W3 ratification-corridor brief. It supersedes
the stale W3 section of WORKBENCH-UI-WAVE-BRIEF-PACK.md, which assumed a
'frontend zero' state (W1/W2 already merged via #295/#299/#329/#327/
#328/#303) and prescribed a Zustand store this repo never adopted. The
reconciled brief names the load-bearing facts the old one glossed:
- /ratify is advisory-only today (routes, never applies); W3's core
backend task is the advisory->in-process flip.
- live proposals carry shape_category='uncategorized', so the safe
category/polarity must be operator-supplied and allowlist-gated, not
hard-coded -- the exact silent-wrong-category path case 0050 guards.
Verification this session: read-only workbench v1 confirmed working
(API serves real deterministic data, honest 404s, traversal rejected,
ratify advisory/no-mutation; 31 python + 104 UI tests green; pnpm build
green).
No runtime/algebra/eval paths touched. Docs only.
