Squashes the arc's work into one commit; the workflow-file edit it originally
carried is excluded (see the end of this message).
## Lane 1 — Workbench recorded a proved answer as ungrounded
With deduction_serving_enabled ratified ON (ADR-0256), workbench/api.py's live
chat route builds a bare ChatRuntime(), so the deduction composer decides
Workbench turns and stamps grounding_source="deduction" — but
_coerce_grounding_source carried a hand-copied whitelist of the six pre-arc
labels and silently rewrote anything else to "none". The runtime comment
reasoned this was inert because "REPL turns do not flow through Workbench's
CognitivePipelineRecord path". True, and irrelevant: the traffic flows the
other way. Stale since 2026-07-24.
Scope is one field. workbench/api.py:818 prefers TurnEvent.epistemic_state,
which read epistemic_state_needed — honest. So the UNregistered path degraded
honestly while the hand-copied whitelist asserted a falsehood; a second copy of
a closed enum was worse than no copy. Hence registration AND derivation:
GROUNDING_SOURCES exposes the Literal's members, and the coercion reads it.
workbench-ui badges/tokens/snapshot follow; enumCoverage.test.ts forces atomicity.
## Lane 2 — the ratification ceremony
The discovery loop was instrumented but not closed. teaching/ratification.py
turns a reviewed decision into a chain record, a corpus commit, and a receipt.
Its design turns on one observation: _ratified_rows DROPS unadmissible rows
silently — correct when serving, a trap when ratifying, because the file grows,
the commit lands, and the band count does not move. So the ceremony refuses to
call an append a ratification until it has re-read the curriculum through the
real loader and seen the chain arrive; a non-admitted append is rolled back.
Validation is a pre-flight courtesy, admission is the proof.
Arena queue entry and ledger reseal are deliberately NOT performed (bridge rule
1); the receipt names them. Front door: `core proposal-queue ratify`, a sibling
of `review` rather than a flag on it.
## Lane 3 — structural closures
- ADR-0263 gains rule 5: absence policy is DECLARED in CAPABILITY_LEDGERS, not
passed at the call site. An AST-matched test fails if a serving path passes
missing_ok again.
- Deductive suite added WHOLE to the pre-push gate: 285 tests in 29s against
smoke's 216 in 62s, so no coverage trade was needed.
- Smoke/CI parity assertion made bidirectional. It was one-directional, and had
drifted.
- test_prior_surface_deduction_binding.py pins correction binding on the
deduction path. The review's diagnosis did NOT reproduce — hash_surface moves
in lockstep — so it pins what is there. Mutation-checked.
- Domain-keyed ADR index over 312 flat-numbered files, explicitly partial.
- Arc-close brief template, plus this arc's own brief filled in against it.
## Lanes 4 and 5 — two premises falsified by measurement, one of them mine
Math 4.2: baseline reproduced (correct=5 wrong=0 refused=495); all four named
cases traced to one seam with each gap isolated by one-variable probes. Then the
number that changes the recommendation: the gap blocking case 0000 affects 1
case in 500, the 'than' gap blocking 0001 affects 2. ADR-0251's prohibition on
per-case growth now rests on a count. No reader change made.
CGA: versor_condition is 0.22% of a turn, not the "~10x proof latency" I claimed
— that multiplied an isolated microbenchmark by a call count and compared it to
a single verdict's latency. The real cost is geometric_product at 33,986
calls/turn (~73%) via cga_inner in search paths. The obvious closed form is NOT
bit-exact (954/4000 in f32); backend.vault_recall's serial fold IS (3000/3000,
worst-rel 0) and is the correct target. cargo test could not run —
static.crates.io is denied by the sandbox network policy — so the Rust parity
question stays open and the typestate lane is carried forward, not shipped
uncompiled.
## Not landed: three lines owed to .github/workflows/smoke.yml
The CI smoke gate is narrower than the local one —
test_pack_draft_serve_boundary.py (ADR-0253 INV-33) has been local-only, unseen
because the parity pin checked one direction. The edit was authored and rejected
at push for lacking the `workflow` OAuth scope, so it is recorded as a named,
dated PENDING_IN_CI exception rather than dropped: the assertion still fires on
any new divergence, and a second guard fires once the three land.
[Verification]: pre-push gates all green — smoke 236 passed, warmed_session 10
passed, deductive 285 passed. Ratification 14, ADR index 5, CLI suites 10.
Grounding/epistemic sweep 741 passed 1 skipped. workbench-ui 598 passed across
73 files, tsc -b clean. capability index 11 passed, digest unchanged. Math
holdout correct=5 wrong=0 refused=495. Committed chain corpora byte-unchanged
after the tests that write to them.
Environment caveat: the repo pins requires-python ==3.12.13, which uv cannot
fetch for linux-x86_64, so `uv sync --locked` fails. All Python runs used a
scratch venv on 3.12.11 with declared deps — not the locked universe, not the
full ~12k suite. The pin was left untouched. Re-run on a 3.12.13 host before
treating this as merge evidence.

Read-only /logos frontend route (Wave M CORE-Logos read-only wave, LG-2):
- route registered via WORKBENCH_ROUTES + lazy ROUTE_ELEMENTS (Substrate section)
- Overview / Identity / Safety tabs over live /logos/packs, /{id}, /safety only
(no /contents or /alignment — those are LG-3 / LG-4)
- 10 Logos* TS interfaces mirrored; NOT_YET_MIRRORED shrunk back to empty
- SafetyVerdict UI badge + dump-enums.py source + enum-snapshot + coverage test
- logos_pack evidence subject (logos:<pack_id>) + round-trip
- bottom strip "proposal mode: none — read-only"; holonomy rendered as
missing_evidence (no tab, no proof card); invalid alignment targets surfaced
honestly in Safety; verdict never mapped to "clear" for warning/unknown
Depends on LG-1 (#737). No mutation endpoints, no engine math in the UI.
First R3 (Theater) piece. Reworks the stale artifact-keyed ReplayRoute into
the turn-keyed hero over the #716 sealed-replay backend, and fully retires
the dead W-026 artifact-keyed machinery on both sides (the NOT_YET_MIRRORED
comment anticipated this).
The hero makes determinism *felt*: pick a journaled turn, CORE re-executes
its prompt in a sealed fresh runtime, and the result renders as a hash
verdict (≡ equivalent / ≠ diverged) + the original/replay DigestBadges + a
leaf diff (critical weighted above informational, each with a ≠ glyph). The
'What this proves' card surfaces comparison_basis + origin_state and states
the honest limit: a divergence means nondeterminism OR origin-state
influence, never rendered on its own as a determinism failure.
Retirement (verified zero serving uses):
- Python schemas.py: removed ReplayComparison/ReplayDivergence/ReplayStatus/
ReplayDivergenceSeverity; scripts/dump-enums.py drops the two replay enums;
both snapshots regenerated (deterministic: dump == committed)
- TS: removed ReplayComparison/ReplayDivergence/ReplayDivergenceSeverity;
added TurnReplayComparison/TurnReplayDivergence (+ basis/origin/severity
unions); NOT_YET_MIRRORED now empty (every engine schema mirrored)
- badges: removed ReplayStatusBadge + ReplayDivergenceSeverityBadge +
meta/enums + their enumCoverage cases (hero renders severity inline)
- api: fetchReplayComparison/useReplayComparison -> fetchTurnReplay/
useTurnReplay (/replay/<turnId>)
- deleted ArtifactList, ReplayComparisonPanel, ReplayDiffViewer,
ReplayMetadataTable, old replay.test.tsx
- App route /replay/:artifactId? -> /replay/:turnId?; conformance row
turn-keyed (loading 'Loading turns...', empty 'No turns recorded yet.')
Tests: ReplayRoute.test.tsx (equivalence hero + honesty card, diverged
critical leaf, informational-only label, replace-mode select, j/k spine).
Full vitest 358 green; workbench Python 34 green; both snapshots deterministic.
Follow-up flagged (not in this PR to keep it focused): the artifact query
hooks (useArtifacts/useArtifactDetail/fetchArtifacts*) are now orphaned but
entangled with the still-live artifact EvidenceSubject kind — a separate
cleanup once an Artifacts route or that subject's fate is decided.
Brief: docs/handoff/wave-R3-briefs-2026-06-13.md (all four R3 pieces).
* feat(workbench-ui): design system v1 scaffold
* fix(workbench): close R1 (GroundingSource enum coverage) + R4 (digest test)
R1 — Promote GroundingSource to a typed Literal in core/epistemic_state.py
so it has the same single-source-of-truth shape as ReviewState. The
existing epistemic_state_for_grounding_source() function already
enumerates the six labels (pack, teaching, vault, partial, oov, none);
this codifies them.
scripts/dump-enums.py now snapshots GroundingSource via the existing
literal_values helper. workbench-ui's enumCoverage.test.ts gains a
fourth assertion that the badge mapping matches the Python source
1:1. Adding a grounding-source value on the Python side without
updating the badge fails the build-time test loud — same discipline
as the other three enums.
R4 — Add an explicit DigestBadge test to StableJsonViewer.test.tsx:
asserts the badge text matches the SHA-256 prefix of the source bytes,
and clicking the badge copies the FULL digest (not the truncated
prefix). Recomputes the expected digest via crypto.subtle to avoid
hard-coding a hex string that could drift.
R2 (component-level reduced-motion enforcement), R3 (EmptyState
copy-CLI affordance), and R5 (`uv run core` packaging paper cut) are
deferred — R2/R3 become meaningful with W-027/W-029, R5 is a
packaging-layer concern outside this PR's scope.
Validation:
- pnpm test: 19 passed (was 17, +1 enum coverage, +1 digest test)
- pnpm build: clean
- pnpm test:enum-coverage: 4 passed
- core test --suite smoke -q: 67 passed
