Brief 4 of the Wave 1 evidence spine — wire the evidence-context architecture
so every route can project into one shared evidence manifold.
Command registry (1A):
- commandRegistry.ts: useSyncExternalStore-backed command store with a cached
snapshot (referentially stable to avoid render loops); useCommands /
useCommandRegistry; recent-items in localStorage (last 10).
- CommandPalette.tsx: reads from the registry; all ten routes are navigation
commands (was Chat/Proposals/Evals hardcoded); fuzzy filter, recent section,
shortcut badges; Router/Fallback split preserved.
- useGlobalKeyboard.ts: Cmd+K palette, Cmd+I inspector, Cmd+1-0 routes, ? help.
Evidence drawer (1B):
- evidenceContext.tsx: EvidenceSubject union (turn|proposal|artifact|
eval_result|none) + useEvidenceSubject hook + EvidenceProvider above the
router Outlet so inspector state persists across route transitions.
- RightInspector.tsx: five evidence projections (was a null stub); reuses the
Brief 2 primitives (MetadataTable, DigestBadge, Timestamp, badges).
- Shell.tsx: visibility driven by inspectorOpen (collapsed by default); no more
hardcoded collapsed=true.
- KeyboardHelp.tsx: shortcut reference dialog.
- TopBar.tsx: palette open state lifted to Shell via props.
Tests: evidenceContext + RightInspector specs added; CommandPalette keyboard
contract updated for the ten-command navigation set (clamp at both ends).
Deferred (noted in spine doc): per-route register()/setSubject call sites,
action-commands (run eval / copy hash), resizable inspector width.
Verified: tsc -b + vite build green; affected specs pass per-file.
Replace blanket no-mutation language with the admitted-corridor rule: ADR-governed path, visible preconditions, auditable telemetry, and replay evidence before action.
Math ratification is documented as the first admitted proposal corridor. Corpus, pack, workflow, arbitrary file, and unadmitted proposal mutation remain forbidden.
SplitPane, TabBar, MetadataTable, DigestBadge, Timestamp, SearchInput.
All token-driven, keyboard-navigable, ARIA-accessible, dark theme,
motion-respectful. No new dependencies — TabBar uses native ARIA
semantics instead of @radix-ui/react-tabs.
PreviewPage updated with all six components in representative states.
Section 1C checked off in wave-1-evidence-spine.md.
Append-only JSONL journal records the exact ChatTurnResult envelope returned by /chat/turn with stable turn_id, trace_hash, all three surfaces, verdicts, and deterministic journal_digest.
GET /trace/turns and GET /trace/{turn_id} serve journal evidence for the Trace route frontend. Read model only; no teaching, pack, or journal-owned engine_state mutation.
Two-pass hardening of the #690 demo so no epistemic state is proposer-mintable:
Pass 1 (sealed corpus, from the reconciliation pass):
- evidence items are references only (evidence_id + content_sha256) resolved
against a committed content-addressed corpus (evidence_corpus.json)
- support derived from committed subject/predicate match; independence from
distinct provenance_root values; proposer support/independence labels are
rejected by the closed schema
- evidence-strength taxonomy (substrate-capability vs interface-contract) in
PUBLIC-DEMO-ROADMAP / DEMO-PACKAGING-CHECKLIST; position-paper refinements
Pass 2 (entailment-decided inference, closes a live false-status hazard):
- the merged inferred leg required only that premise IDs resolve — a claim
with no support citing one unrelated record as a premise was assigned
'inferred' (empirically confirmed). inferred is now decided by
generate.proof_chain.entail (sound+complete ROBDD) over resolved corpus
premises, cross-checked against the independent truth-table oracle
(evals.deductive_logic.oracle, no shared code); proof keys + oracle verdict
in the trace; disagreement => defensive refusal; refutation => contradicted
- committed adversarial scenario unrelated-premise-still-undetermined proves
the attack now lands on undetermined
- corpus seal (corpus_sha256) pinned into every evaluated trace; scope
refusals no longer consult the corpus; corpus cache hands out copies;
claim subject/predicate constrained to atom-compatible snake_case
- .gitignore: private packet dir, agent worktrees, tooling artifacts
Validation: 30 demo tests; 96 across all three demo suites; 7/7 scenarios
double-run byte-identical; 61 architectural invariants green.

The ratified capability, through the existing mutation owner only:
- teaching/proof_promotion.py — pure decider. Fresh-reads every premise AND
the claim from the store (claim_entry_index; forms never proposer-supplied),
strict status compares (no parse-defaulting), reading_certified must be the
boolean True, engine certification via the pinned deductive engine,
proposer_payload accepted and provably never read (del before use; poisoned-
mapping test), certificate digest emitted for D4 trace-hash folding. Zero
mutation; zero vault.store calls; zero status writes (proven with the
INV-21/INV-29 detectors themselves).
- vault/store.py::apply_certified_promotion — the single transition site.
Independently re-verifies: byte-for-byte replay under DEDUCTIVE_ENGINE_PIN,
promotion_positive, live claim form/reading/status cross-checks, live
premise form/reading/status cross-checks (staleness refuses). Fabricated or
tampered certificates flip nothing; authority is live store state plus
recomputation, never the artifact.
- generate/proof_chain/engine_pin.py — DEDUCTIVE_ENGINE_PIN mirrors the
deductive_logic_v1 lane SHA; sync pinned by AST test against
scripts/verify_lane_shas.py.
- Consistency fix found in lookback: both promotion sites now stamp
epistemic_state alongside epistemic_status (the ADR-0148 site left the
stored state tag stale; recall recomputed it, but the stored key lied).
Obligations: all six strict-xfail markers retired and live (O1/O2
strengthened to prove the transition through the vault owner); the
module-existence pin deleted per its own docstring; the two remaining
honesty pins kept. INV-21 allowlist unchanged; INV-29 allowlist unchanged
({vault/store.py}); INV-29's 29c visibility floor raised 2 -> 3 to cover the
new site.
No runtime turn path calls promotion; the deterministic demo is PR D.
Validation: new suite 49 passed; obligations 8 passed (0 xfail remaining);
invariants 66 passed; certificate 27 passed; 0148 6 passed; epistemic 20
passed; smoke files green; lane SHAs verified.
Architect-directed ratification: D1 (pure decider / vault-owned mutation),
D2 (reading stays curator-certified in the first cut), D3 (exact predicate,
including REFUTED -> no transition), D4 (certificate fields + trace-hash
folding), and INV-29 as the permanent transition-site boundary, all ACCEPTED.
Two fail-closed realizations recorded under D3: the claim form is fresh-read
from the claim's own stored entry (never proposer-supplied), and zero-premise
tautology certificates refuse rather than promote in v1.
Docs-only: no runtime behavior changes in this commit. P3 implementation
(teaching/proof_promotion.py + VaultStore.apply_certified_promotion) follows
in the same PR as separate commits.
Pure evidence substrate for proof-carrying coherence promotion. No
promotion, no vault import, no status transition, no teaching-path
change; ADR-0218 stays Proposed.
- generate/proof_chain/certificate.py: frozen PromotionCertificate
(version/claim_form/premise ids+forms+statuses/entailment_trace/
engine_pin/decision/reason, canonical_json with sort_keys+compact
separators); build_certificate runs evaluate_entailment_with_trace
over entry_id-sorted premises; verify_certificate rebuilds from the
embedded forms and accepts iff byte-identical — tampered forms/claim/
trace/decision/reason/ordering/version all fail replay, structural
breakage fails closed as malformed_certificate.
- promotion_positive is necessary-not-sufficient: entailed over a
non-empty all-coherent recorded premise set; REFUTED/UNKNOWN/REFUSED
verify as themselves but are never positive; zero-premise tautology
certificates fail-closed non-positive in v1.
- engine_pin is recorded provenance; pin tampering is caught only via
caller-supplied expected_engine_pin (P3 must pass the lane SHA) —
limit pinned by dedicated tests.
- entail.py: docstring-only fix removing the incorrect ADR-0206
attribution (numbering collision); now cites ADR-0218. Zero behavior
change. generate_claims.py:74 still carries the label (serving-frozen
surface, flagged for follow-up).
- No xfail markers retire: every PR-A obligation binds to the P3
promoter, which must not exist before ratification. The certificate-
shaped halves of O1/O7 are proven for real in
tests/test_proof_chain_certificate.py (27 tests). ADR phasing bullet
and obligations docstring record the reconciliation.
Validation: certificate 27 passed; obligations 3 passed + 6 xfailed;
architectural invariants 61 passed (INV-21/INV-29 green, allowlists
unchanged); entail/builder/rules 61 passed; smoke files 95 passed.
PR A of the stack specified by docs/issues/proof-carrying-coherence-promotion.md.
No runtime change; no promotion behavior; ADR-0218 is Proposed, not ratified.
- ADR-0218 (Proposed): rulings the issue Section 9 demands — extend the
existing mutation owner (policy decides in teaching/proof_promotion.py at
P3, only vault/store.py mutates), reading stays curator-certified in the
first cut, exact fail-closed admissibility predicate, certificate folds
into trace_hash. Records two substrate corrections: proof_chain Phase 2
(2.1-2.4) is already implemented, and ADR-0148 already automates an
energy-arm promotion.
- INV-29 (passing): epistemic-status transition sites are allowlisted.
ADR-0148's in-place promotion proved INV-21's AST scan cannot see
status transitions (they are not store() calls) — the boundary the
issue calls highest-risk did not actually cover the riskiest shape.
Allowlist pinned to {vault/store.py} BEFORE any promoter exists;
detector mutation-proven non-vacuous (29b/29c).
- Obligations O1-O5, O7 as strict xfail (executable spec; ImportError today;
strict=True forces the P3 PR to retire markers and pass for real) + three
honesty pins that flip red if promotion is wired without review.
Validation (worktree off main@187b008b, python -m pytest):
- tests/test_proof_carrying_promotion_obligations.py: 3 passed, 6 xfailed
- tests/test_architectural_invariants.py: 60 passed (56 prior + 4 INV-29)
- smoke file set: 94 passed
- proof_chain/entail/binding-graph/ADR-0148 set: 84 passed
- epistemic/teaching set: 40 passed
- scripts/verify_lane_shas.py: 8/9 pinned lanes match incl. deductive_logic_v1;
public_demo missed on the known env wall-clock budget flake (47.6s > 30s),
pre-existing and unrelated (diff is docs+tests only).
§3.4 said promotion "requires a curator-mediated coherence judgment." That
over-states a necessity. ADR-0021 §3 only requires promotion be a function of
coherence with the reviewed field. For claims *deductively entailed* by
already-COHERENT facts, the entailment proof IS that coherence judgment and can
be machine-certified by the sound deductive_logic_v1 engine — the logical arm of
the "structural coherence metric" ADR-0021's v2 gap already names.
- position_paper.md §3.4: split "own asserted output" (no standing — kept) from
"deductively entailed from COHERENT facts" (proof = coherence judgment);
relocate review to the *reading*, not the deduction; flag the proof-carrying
path as specified-but-unwired with a link to the new issue.
- teaching/epistemic.py: the EpistemicStatus docstring claimed transitions are
"computed from coherence" — they are not; review_correction carries status as
a curator-supplied input. Docstring now states this honestly.
- docs/issues/proof-carrying-coherence-promotion.md: thorough spec for the
unbuilt capability (scope, the reading hazard, INV-21 impact, trust boundary,
falsification tests, phased plan, proposed ADR-0218).
No runtime behavior change. Green: test_epistemic_invariants,
test_epistemic_phase3_state_tagging, TestINV21OneMutationPath (15 passed).
Tool Authority Demo (#688) was still tagged 'draft PR / in review' but it
merged at c55f7dfb. Hybrid Verification Demo (#687) lacked the claims-authority
framing and the agreement-is-not-safety finding. Reposition both as merged
evidence, name the next public evidence target, and align epistemic-state vocab.
- #687 = authority over claims; #688 = authority over proposed tool actions.
- Removed stale 'In progress / draft PR / in review' status on #688.
- Added explicit next-target ordering: Epistemic Truth-State -> Embodied
Authority Simulation -> SaaS/On-Prem Boundary.
- No named-company, outreach, or production/robotics overclaims introduced.
- Explicit System 1/2 framing in thesis and §2 (Claude proposes; CORE decides)
- Named Bounded Transition Guarantee (v2.1) callout box in §2
- Conditioned false-positive claim on correctly specified Anchor (§1)
- Named Type-Safe Local Closure security model in Lens layer and §5 Signal 1
- §7 renamed 'The Ask — Hybrid Mode Wedge' with MCP-shaped experiment framing
- §5 stats (716/716, 0 wrong) explicitly tied to BTG, not tuning/sampling
- §6 Honest Limits: explicit Hybrid vs Native Mode distinction added
- Harmful variant table row: 'licensed scope is a ratified human policy decision'
ADR-0184 S4b — the replay/provenance equivalence boundary, the
precondition for any semantic-primary path. After #685 the in-repo
legacy path delegates to the semantic boundary, so old-vs-new is
vacuous; the durable reference is a pinned canonical trace artifact
(evals/gsm8k_math/equivalence/v1/, 937 problems) whose authority is
the #684/#685 cross-tree differentials (documented provenance chain).
- state/provenance.py: replay_is_faithful — the replay bridge's law as
a checkable structural property (no verify/pool import; covered by
the #685 authority scan).
- equivalence/trace.py: canonical traces (worlds, candidates, order,
multiplicity, classifications, resolutions) + authority_violations
re-deriving the pool commit law from trace content.
- scripts/verify_semantic_equivalence.py: check / --update gate
mirroring verify_lane_shas.py.
- tests/test_adr_0184_s4b_replay_equivalence.py: full-corpus live-vs-
pinned equality, corpus-wide authority + faithfulness, and 17
single-mutation non-vacuity proofs.
Pure additions; verify.py/pool.py untouched; no serving, CLAIMS,
metrics, or lane pins moved.
ADR-0184 §7 S4: add generate/derivation/state/source.py — the single
boundary through which semantic-ledger worlds become pool candidates —
and swap pool.py's accumulation source to semantic_state_candidates().
accumulate.py keeps its public surfaces as thin compatibility wrappers
(ADR-0184 §10). Byte-identical over the 937-problem differential;
verify.py / pool.py remain the sole commit authority (structural
no-authority-import scan over state/, non-vacuous).
Also: docs/analysis design note for the S3–S5 boundary stack, and a
drive-by ruff F541 fix in r1_reconstruction.py (rf->r, zero behavior).
Stop-and-document outcome for issue #680's final runtime wiring. The
serving turn has no lawful in-turn ContemplationResult or provider: the
sole QUESTION_NEEDED producer (generate.contemplation.contemplate) is an
off-serving growth organ that runtime is forbidden to call, and no
plumbing carries its artifact into the turn. Wiring is deferred to a
lawful acquisition slice; chat/runtime.py is left untouched.
Rewrites the Q1-D ASK bus delivery scoping document into the durable decision record for decisions implemented in #668. No code or runtime behavior changes.
Accepts the ASK + VERIFIED serving-integration scoping briefs.
No served-surface code is introduced. ASK is identified as the next gated serving slice; VERIFIED remains blocked on a gold-free second reader and explicit eval-gold serving ban.
Resolve the one open S2-1 design decision in the doc before it leaves draft:
VERIFIED must NOT reuse ReachLevel.APPROXIMATE or the [approximate] prefix.
- §0: add the claim-vs-reach caution — VERIFIED is a disclosed-surface
*license / verification claim*, not a point further out on the speculation
scale; it is more LICENSED than strict/gold, not more speculative. Record the
principled three-axis decomposition (Disposition × DisclosureClaim × ReachLevel)
and allow v1 to collapse to a distinct ReachLevel.VERIFIED iff it carries its
own admissible-set, rationale, and [verified] prefix.
- §4: replace the open question with the settled S2-1 decision (Shay's wording):
VERIFIED gets a distinct disclosed-surface mode with its own deterministic
[verified] prefix; APPROXIMATE is for bounded estimates, VERIFIED for
independently-confirmed answers under the canonical-comparison contract.
- §1 SQ-5, §9 S2-1, §11 non-claims: propagate — only the enum shape
(distinct ReachLevel.VERIFIED vs a separate DisclosureClaim axis) is left to S2-A.
Still scoping only — NO CODE. Stays DRAFT pending Shay's design-lock.
Scope the frontier after the frozen R1–R4 comprehension ladder: the
served-surface disclosure machine and its first two tenants. Scoping
only — NO CODE.
- session doc §1.5 — the pre-question limitation pass / intake gate:
classify the limitation KIND before choosing a disposition (asking is
one of several). Key phrase: question-asking is the intake mechanism
for resolvable missing state; limitation assessment is the gate that
decides whether intake is appropriate.
- Doc 1 (primary) — the Epistemic Disclosure Bus:
EpistemicState + LimitationAssessment → ServedDisposition, two axes
(DISPOSITION × the existing ReachLevel). VERIFIED is the ONLY v1
tenant; ASK/PROPOSE/REPORT/SCOPE reserved. Grounded in the built-but-
inert ADR-0206 seam (govern_response/shape_surface; _canonically_verified
returns None at verify.py:188). Honours the 2026-06-06 dead-path
verdict: v1's VERIFIED producer is a comprehension-organ answer (R2
first, R4 second) with independence in the READING not the solving,
validate-first holdout (INV-25) BEFORE any widening, behind a new
verified_serving_enabled=False, GSM8K seal untouched.
- Doc 2 (companion) — Q1 question articulation: maps the four ASK
dispositions onto the shipped failure_family registry; the
missing_total_count / missing_weighted_total reclassification (decide
with tests, never silently re-key); the grounded-rendering wrong=0
invariant; the structured-residue-on-refusal gap; Q2 re-enters the
gate (augment + rerun, never mutate). Second bus tenant.
HOLD for review.
Records the design reached in discussion: the first real skill of contemplation
is typed, deterministic, failure-family-driven question generation. A question is
a typed request for missing state, not a conversational habit. Proposes
core/epistemic_questions/ organ (EpistemicQuestion, MissingSlot, AnswerBinding),
the QUESTION_NEEDED terminal distinct from PROPOSAL_EMITTED, and the Q1/Q2 PR
ladder. Traces the connection to the ServabilityBlade clarify mode and the
minimal-sufficient-question discipline.
Closes the CMB ladder with a docs-only lockfile. No behavior change.
- New docs/analysis/combined-rate-capability-ledger-2026-06-08.md: the frozen
R4 v1 claim, supported solved grid, solver/reader boundaries, the three
proposal-allowed deferrals, router/contemplation integration, the
domain-precedence adjudication (named, with proof cases cmb-11/15/12·13·14),
a prominent non-claims list, and the verification lanes. Every cited number
re-confirmed against the lanes: gold 19/19 (6/5/8), solver 6/0/5, reader
11/0/8 -> answers 6/0/13; the 7 R4 test files 93 passed.
- Updates comprehension-organ-capability-ledger-2026-06-08.md to fold R4 in as a
fourth organ: organ block, 4-organ router + cmb_* namespacing, a named
domain-precedence section, R4 lane rows, and a reframed deferred/next that
points the next frontier at served-surface epistemology (not more comprehension).
Honest accounting: 1 pre-existing red (test_findings_reset_between_turns) is red
on clean origin/main and imports nothing from R4 — unrelated.
Off-serving unchanged (sealed); no generate.derivation / core.reliability_gate.
The mandatory lookback before CMB-d (3+ PRs on one surface; next-phase boundary). A 5-dimension
read-only fan-out audit over the 10-item checklist found the CMB-a/b/c substrate composes cleanly:
25 solid / 4 drift / 8 gap / 1 reader hazard. Doc:
docs/analysis/cmb-lookback-review-2026-06-08.md.
Fixes the one real hazard (H3): a query attributing the answer to a SINGLE agent ('how many words
does Alice type' with a distractor second rate) wrongly claimed the substantive
combine_mode_ambiguous — a hygiene over-claim that would corrupt the shared router in CMB-d. The
combined-query gate now excludes single-agent 'does <Agent>' attribution (_SINGLE_AGENT_QUERY) and
steps aside as not_combined_rate_shaped; the genuinely-combined forms ('do they' / 'are produced' /
'does it') still yield combine_mode_ambiguous. Pinned by gold cmb-16 + a reader test.
The review also resolves the CMB-d failure-family classification (input_shape:
not_combined_rate_shaped; must_remain_refused incl. rate_unit_mismatch — DECISIVELY, the reader has
no dimension representation so it cannot tell convertible from incompatible units; proposal_allowed:
combine_mode_ambiguous, missing_second_rate) and enumerates the live CMB-d registry preconditions
(not_combined_rate_shaped mapping, rate_unit_mismatch/non_integer_solution string collisions,
non_positive_net_rate family, Organ/ALL_REASONS extension). Provenance false-alarm (stale local main
checkout) noted + verified against origin/main.
gold 19/19 (6/5/8); reader 11/0/0 + 8 refused-correct; solver 6/0 + 5/0; 0 hygiene breaches; 123
tests; serving + R1/R2/R3 unchanged.
The 2026-06-08 practice-attempts/servability-blade session note under-referenced the substrate
that already ships the serving half of its design. Doctrine ('wrong=0 = no false presentation of
epistemic status') stands; the build plan must reuse existing organs, not fork parallel ones.
Adds a binding Amendment + reframes sequencing:
- ServabilityDecision/ServabilityBlade => advance ADR-0206 core/response_governance/ (ReachPolicy /
govern_response / shape_surface, ReachLevel STRICT<APPROXIMATE<EXTRAPOLATE<CREATIVE, gated STRICT,
already disclosing [approximate]) — NOT a new object.
- the epistemic_state Literal => reuse core.epistemic_state.EpistemicState (ratified taxonomy), not
a smaller renamed enum.
- ProblemAttemptSession => extend core/comprehension_attempt/, don't fork.
- first activation = produce reserved VERIFIED via canonical comparison (scoping doc already exists),
consume through govern_response/shape_surface, prove on the yardstick, one state at a time.
Preserves the research trail (amendment, not rewrite). Docs only.
Records the wrong=0 refinement reached in discussion: wrong=0 is not a binary
answer/refuse gate but 'no false presentation of epistemic status'. Practice/
contemplation may explore typed, isolated candidate guesses; served output needs
a servability blade with more modes than verified|refuse. Proposes
ProblemAttemptSession (PRA) and ServabilityDecision (SRV), sequenced PRA -> REL ->
SRV, and traces the idea to the R1/R2/R3/CMB reader trajectory. Session doc, not
an ADR yet.
First rung of the combined-rate ladder, off-serving (imports no generate.derivation /
core.reliability_gate). Claims exactly: the combined-rate setup ruler is defined and
gold-valid. No reader/solver/wiring yet — no capability claim.
- generate/combined_rate_comprehension/: local RateUnit (decoupled from R3), CombinedRateProblem
(two-explicit-rates + per-query-slot guard; effective_rate = rate_a +/- rate_b; non-positive net
left to the solver, not the model).
- evals/combined_rate_oracle/: span-free signature (sum commutative / difference ordered) + a
NON-VACUOUS validator. 17 gold fixtures: 6 solved (full combine_mode x query grid), 4
solver_refuses, 7 reader_refuses (the complete refusal taxonomy + the 2x2 domain-entry grid).
Adversarial 5-lens verification returned fix_first; the validator now cross-checks every solved
gold and solver_refuses reason against the canonical arithmetic (_canonical_outcome) so a
mislabelled / arithmetically-impossible fixture is rejected (meaningful-fail per CLAUDE.md), with
dedicated tests. Added eff<0 and eff=0/time coverage fixtures; removed a dead determinism guard.
gold 17/17 valid; 25 oracle tests; R1/R2/R3 + router-hygiene + serving all unchanged.
Doc: docs/analysis/cmb-a-combined-rate-ruler-2026-06-08.md
Consolidation/true-up after #646-#648. Records the off-serving comprehension
system as one ledger: R1 relational arithmetic, R2 finite-integer constraints,
R3 explicit single-rate + exact minute/hour conversion, the router/contemplation/
proposal loop, the proposal-review reporter, idle_tick read-only visibility, and
the standing router-organ-hygiene invariant. Pins the whole-system lane state
(answer_wrong==0 everywhere) and the off-serving import-disjointness guarantee.
Also fixes a documentation-integrity defect the R2 batch introduced: the R2 ADR
took number 0211, which collided with ADR-0211 (Conformal Falsification Bench,
2026-06-06 — earlier, test-pinned, depended on by ADR-0216). The conformal ADR
keeps 0211; the R2 ADR is renumbered to the next free number 0217. Ratified
decision content unchanged; only the identifier and references move.
Option A (text-faithful): RateProblem gains time_unit (the duration's ORIGINAL unit; time stays int; defaults to the rate denominator). The SOLVER converts via convert_time -> exact Fraction -> int-or-refuse(non_integer); Fraction never leaves the solver, no floats. The reader accepts a convertible (minute<->hour) duration mismatch (keeps original time_unit); a non-convertible one still refuses rate_unit_mismatch. Signature includes time_unit ('30 minutes' != '30 hours').
Gold: r3-09 flips reader_refuses -> SOLVED (60 mph for 30 min = 30 mile, exact 1/2 hour; distractor 1800 rejected); new r3-13 non-convertible (3 gallons) stays rate_unit_mismatch. R3 gold 13/13; reader 9/0/0 -> answers 7/0/6 (setup_correct 8->9). Failure-family: rate_unit_mismatch now non-convertible-only -> still unsupported_rate_duration proposal surface; router-hygiene invariant stays green; R1 7/0/3, R2 10/0/0 unchanged. 119-test smoke green incl. invariants. Off-serving, no float path.
No organ may claim a substantive boundary on text outside its domain — on every OTHER organ's gold, a refusal must map to the non-substantive input_shape family (not-my-domain), never a substantive boundary/growth surface. This is what lets one organ suppress another's legitimate proposal via boundary-first (caught at N6, R3e, R3.1). MUST-PASS gate before any new organ joins route_setup. Currently green for R1/R2/R3. + standing-rule doc.
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.
