CMB (r4_combined_rate) now participates in route_setup and bounded contemplation. R1/R2/R3 readers/
solvers, the CMB reader/solver/oracle, and serving are all UNCHANGED — pure shared-infra integration,
no new comprehension capability (that was CMB-c).
- model.py: Organ += r4_combined_rate.
- classify.py: classify_cmb + _cmb_signature (organ-tagged, cross-organ-distinct) + cmb_reason —
namespaces CMB reasons cmb_* before the reason-string-keyed registry sees them, so a CMB boundary
never inherits R2/R3's family for the SAME bare string (R3 rate_unit_mismatch is a GROWTH surface;
R2/R3 non_integer_solution carry other owners). not_combined_rate_shaped/empty stay bare -> the
cross input_shape family (router hygiene).
- failure_family.py: Owner += r4; input_shape += not_combined_rate_shaped; 8 CMB families
(must_remain_refused: cmb_unit_mismatch [until a dimension registry exists — NOT forever],
cmb_combine_ambiguous, cmb_underdetermined, cmb_non_positive_net, cmb_non_integer; proposal_allowed
-> cmb_gold_fixture: cmb_unsupported_rate_count/_reciprocal/_clock_interval).
- pass_manager.py: _solve_and_verify_cmb (solver Refusal -> REFUSED_KNOWN_BOUNDARY, never a proposal).
CMB-over-R3 domain-precedence rule (cmb_is_authoritative): when CMB POSITIVELY recognizes
combined-rate shape (a setup, or a substantive cmb_* refusal — NOT the input_shape step-aside), R3's
broader single-rate over-read of the SAME text is inadmissible — for BOTH routing (veto R3
setup_correct) and family attribution (suppress R3 so CMB's sharper diagnosis owns the
terminal/proposal). This came from a pre-build cross-organ pressure-test: R3 reads 'Anna and Ben
paint together; Anna paints 3 rooms/hour. How many do THEY paint in 4 hours?' as a single rate and
would confidently answer a wrong 12. The rule fixes that (-> REFUSED) without touching R3. It does
NOT mean 'CMB always wins': on input_shape CMB cedes (a plain single-rate car problem routes to R3
and solves 180). Narrow CMB<->R3 instance of a future general domain-specificity adjudication.
Tests: new test_cmb_router_contemplation (full terminal matrix; cmb-11 veto-no-wrong-answer; cmb-15
cede-to-R3; solver-refusal-never-proposes; CMB-owned proposal-only artifacts mounted:false; no gold
ambiguous; off-serving AST). Extended router-organ-hygiene to CMB x R1/R2/R3 (0 breaches).
test_setup_router/test_r3_router_contemplation attempt-count 3->4; test_failure_family ALL_REASONS +
growth set. 97 CMB-d tests; 597 broad-net pass (1 unrelated pre-existing red); CMB organ lanes green.
classify_r3 normalizes the rate reader into a ComprehensionAttempt; route_setup now tries R1/R2/R3 (same exactly-one-setup_correct rule); the pass manager solves+verifies a routed r3_rate setup (solve_rate + reused answer-choice verifier); unsupported_temporal_state dropped from the unsupported-family set so temporal_state -> REFUSED_KNOWN_BOUNDARY. Organ gains r3_rate.
Terminal matrix (verified): 6 solved->SOLVED_VERIFIED; rate_unit_mismatch+combined_rates->PROPOSAL_EMITTED(unsupported_rate_duration); non_integer/missing_time/temporal->REFUSED_KNOWN_BOUNDARY; exactly 2 proposals (the rate-like gaps only).
REGRESSION CAUGHT+FIXED: R3's reader returned missing_rate (a substantive boundary) on non-rate R2 text, blocking r2-011's legitimate missing_total_count proposal via boundary-first. Fix: missing_rate only when a duration is present; else not_rate_shaped -> input_shape (not-my-domain) — same discipline as the N6 category_pair_not_found fix. r2-011 proposes again; R1/R2 unaffected. R1 7/0/3, 15-case 15/0/0, R2 10/0/0, R3 8/0/0 unchanged; off-serving; 121-test smoke green incl. invariants + idle contract suites.
docs/analysis/r3-rate-inventory-ledger: R3 v1 state (reader 8/0/0 + 4 refused -> answers 6/0/6; gold 12/12), per-fixture table, the compound-unit substrate, covered families + R3.2/R3.3 deferrals.
core/comprehension_attempt/failure_family.py: makes unsupported_rate_duration REACHABLE as a growth surface (proposal_allowed) mapping rate_unit_mismatch + combined_rates — both emitted ONLY after a rate clause is recognized, so always rate-like (anti-over-propose discipline, same as the N6 fix). missing_rate/time/quantity -> rate_underdetermined boundary; temporal_state -> unsupported_temporal_state boundary (clock detector can fire on non-rate text, NOT a safe growth surface); query_target_unrecognized/no_query -> input_shape. Owner gains 'r3'. 107-test smoke green incl. partition + contemplation + invariants; R1 7/0/3 + R2 10/0/3 unchanged; off-serving.
generate/contemplation/{findings,pass_manager}.py: a single bounded pass — route (N3) -> classify+enrich (N4) -> terminal -> maybe emit proposal-only (N5). No loops/daemon/L10. Seven terminals: SOLVED_VERIFIED / REFUSED_KNOWN_BOUNDARY / REFUSED_UNSUPPORTED_FAMILY / CONTRADICTION_DETECTED / PROPOSAL_EMITTED / AMBIGUOUS_ORGAN / NO_PROGRESS. R2 solved+verified end-to-end; R1 routed setup is SOLVED_VERIFIED (numeric answer stays the eval lane in v0).
Hazard found+fixed: N6 exposed that category_pair_not_found fires on ANY non-R2 text, so mapping it to a growth surface made gibberish falsely PROPOSAL_EMITTED. Reclassified it to input_shape and made missing_category_pair reserved — only the PRECISE missing_total_count/missing_weighted_total remain reachable growth surfaces. Classification is boundary-first (input_shape non-blocking), so a problem one organ recognizes as a substantive boundary never proposes against the other's broad refusal.
Acceptance proven: known correct refusal -> no proposal; unsupported gap -> proposal-only artifact (exactly the 2 missing_* gaps over the gold); answer-key contradiction -> CONTRADICTION_DETECTED; organ conflict -> AMBIGUOUS_ORGAN. 188 tests green incl. architectural invariants; R1 7/0/3 + R2 reader 10/0/0 unchanged; off-serving.
core/comprehension_attempt/failure_family.py: partitions every reachable organ refusal reason (R1 reader/admissibility, R2 reader/solver/answer-choice) into a named FailureFamily declaring owner / must_remain_refused / proposal_allowed / safe_next_action / proposal_target. family_for_reason is total + unambiguous (partition asserted by test); enrich_family resolves an attempt's family.
Only THREE families are growth surfaces (proposal_allowed=True): the R2 missing_category_pair / missing_total_count / missing_weighted_total gaps. All other reasons are correct wrong=0 boundaries (refuse, no proposal) — correct refusal != missing capability. answer_key_contradiction is a report verdict (no reason). Reserved R3 families forward-declared. 9 tests incl. whole-surface coverage + partition.
