From 3cd5139a2de862ef88dbc41eae1e816cf0cbc061 Mon Sep 17 00:00:00 2001 From: Shay Date: Tue, 16 Jun 2026 23:12:29 -0700 Subject: [PATCH] fix(derivation): address remaining Inc2 blockers (locate_rate_verb via matcher token, dispatch test, lookback accuracy, narrow symbols, tests) - recognizer_match: updated _CURRENCY_AMOUNT_RE + parsing to populate 'rate_anchor_token' localized to the rate span (prevents whole-sentence 'a' hazard from 'a lemonade stand'). - recognizer_anchor_inject: use 'rate_anchor_token' from anchor (with allowed-set check); fallback only if absent. Added Alexa-style confuser coverage. - injector: narrowed _CURRENCY_SYMBOL_TO_UNIT to $ only for Inc2. - tests: strengthened dispatch to require live-registry non-empty + roundtrip_admissible; added rate_anchor_token confuser test proving 'per' (not earlier 'a') is used; roundtrip asserts already present. - lookback: updated to 10 files, 10+6 test counts, current head reality, shas/runner status exact, no rebaseline. - math_candidate_graph comment already corrected in prior. All Semantic Rigor / wrong=0 invariants preserved.
