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).
Replaces VaultRoutePlaceholder with the real route over the R2-B
/vault read substrate (#712).
- TS mirrors VaultSummary/VaultEntry; both removed from NOT_YET_MIRRORED.
Also fixes a latent ErrorCode drift: adds 'evidence_unavailable' to the
TS union (present in Python schemas, missing in TS) — the route branches
on it.
- fail-closed is the design: a missing/unpersisted vault (the 501
evidence_unavailable signal, or persisted=false / entry_count=0) renders
the honest absence card as the PRIMARY state, naming the opt-in
RuntimeConfig.persist_session_state pointer — not a generic error, no
skeleton theater
- with data: summary strip (entry_count, store_count, reproject_interval,
max_entries, source_path) + VirtualizedList of entries with
epistemic_status / epistemic_state pills and versor_digest DigestBadge
- exact-recall doctrine: renders only backend fields; never computes or
displays a similarity/relevance proxy (runtime recall is exact cga_inner)
- selection publishes the vault_entry subject (inspect-param only, via
setSubject + setInspectorOpen; EvidenceUrlSync writes ?inspect=vault:N);
a URL-restored identity-only subject is hydrated once entries load
- Vault row added to routeConformance MOUNT_ROUTES — the fail-closed
absence asserted as the primary contract
- tests: fail-closed card (not error), summary+entries, no-similarity-score
doctrine, vault_entry subject publication, j/k spine
Token-only styling (hexScan green).
Replaces PacksRoutePlaceholder with the real triad route over the R2-B
/packs read substrate (#712).
- TS mirrors PackSource/PackSummary/PackDetail; PackSummary/PackDetail
removed from NOT_YET_MIRRORED (drift gate now enforces them)
- new design primitive TreeView (src/design/components/TreeView): a
deterministic, keyboard-driven JSON tree — object keys sorted, array
indices in order, no animation; ←/→ collapse/expand, ↑/↓ + j/k move,
Home/End jump, Enter toggles; registers its shortcuts only while focused
(KeyboardHelp never advertises tree controls when no tree is on screen)
- list pane: VirtualizedList + useListNavigation (j/k) + SearchInput; rows
show pack_id, source, version, language/modality, determinism_class pill
- detail pane: Panel + TabBar (Manifest / Checksums / Raw); Manifest renders
via TreeView; Checksums is the verify affordance — manifest_digest and
declared checksum as DigestBadges plus the per-field manifest checksums
table (the checksum-hashes-the-bytes-on-disk doctrine made visible); Raw
collapsed by default
- selection publishes the pack subject (R2-S), records /packs/<packId>
(replace), pushRecentItem on visit
- Packs row added to routeConformance MOUNT_ROUTES (loading 'Loading
packs...', error 'No packs mutation occurred.', empty 'No packs
discovered.' + core pack validate <path>)
- tests: TreeView (sorted/collapsed/expand/collapse/focus/click/empty) +
PacksRoute (list, replace-mode select + manifest tree, checksum verify
affordance, j/k spine)
Token-only styling (hexScan green).
Replaces the RunsRoutePlaceholder with the real triad route over the
R2-B /runs read substrate (#712).
- TS mirrors RunSource/RunSummary/RunTurnRef/RunDetail; all three classes
removed from NOT_YET_MIRRORED (drift gate now enforces them)
- list pane: VirtualizedList + useListNavigation (j/k) + SearchInput;
rows show source, session_id, turn_count, relative timestamp, a
checkpoint badge (present + revision vs 'no checkpoint'), and any
evidence_gap rendered honestly in-row (never hidden)
- detail pane: Panel + TabBar (Turns / Manifest / Raw); every turn row
is an anchor to /trace/<turn_id> (backend-provided trace_path) with the
trace_hash as a DigestBadge — the cross-link is the point of this route;
turn list pages via turn_limit ('Load more turns')
- selection publishes the run subject (R2-S) and records /runs/<sessionId>
in the URL (replace), pushRecentItem on visit
- Runs row added to routeConformance MOUNT_ROUTES (loading 'Loading
runs...', error 'No runs mutation occurred.', empty 'No runs recorded
yet.' + core chat)
- RunsRoute.test.tsx: list evidence, in-row gap, replace-mode URL select,
trace cross-link hrefs, manifest tab, j/k keyboard spine
Token-only styling (hexScan green); full vitest 339 green.
Replaces the W-026 501 stub. Re-executes a journaled prompt in a sealed
fresh runtime (ChatRuntime(no_load_state=True): no checkpoint load, no
checkpoint write, no proposal lineage) and compares the envelope
leaf-by-leaf against the recorded TurnJournalEntry.
Design correction vs the scoping doc (amended in-doc): journaled turns
each ran in a fresh ChatRuntime(), never one continuous session, so
genesis-PREFIX replay would manufacture spurious divergence; shipped
basis is sealed_fresh_runtime_single_turn (O(1)). origin_state:
"unrecorded" — the journal does not record whether the original turn's
runtime loaded a checkpoint, so divergence is reported as nondeterminism
OR origin-state influence, never disambiguated.
- workbench/replay.py: pure comparison + injected executor; every
TurnJournalEntry field classified critical/informational exactly once
(exhaustiveness enforced by test)
- api.py: route wiring under _CHAT_TURN_LOCK; runtime failure -> 500
runtime_unavailable, no comparison may be fabricated
- schemas: additive TurnReplayComparison/TurnReplayDivergence (W-026
artifact-keyed pair retires with the frontend Replay Moment PR)
- tests: 10 obligations incl. tamper-prompt, tamper-leaf precision,
no-execution-no-comparison, no-trace (journal + engine_state bytes),
wall-clock tolerance, sealed-construction proof
- snapshot regenerated; NOT_YET_MIRRORED debt entries for the two new
classes (mirrors land with the frontend PR)
- api-contract-v1.md § Replay rewritten for the turn-keyed shape
- EvidenceChainRail: the spine's seven stages rendered per subject with
the honesty contract — lit/hollow/dim derive ONLY from carried fields
(a trace hash lights 'replay' as RECORDED, never as verified); pure
deriveStages() with meaningfully-fail tests (remove one field -> exactly
its stage hollows).
- Hash display standard: DigestBadge default 12-char + copy everywhere;
CopyableHash consolidated away (2 call sites swapped, file deleted).
- Typography: tabular-nums on MetadataTable values + eval metrics;
text-wrap balance on Panel titles + EmptyState statements.
- Selection unification: new --color-selected-bg/-border tokens; selected
(persistent) vs focused (transient) now visually distinct across
Proposals/Replay/Evals lists; focus-ring no longer doubles as selection.
- EmptyState gains a deterministic monochrome inline-SVG glyph.
- Panel adopted in Evals lane list + Proposals queue.
- Doctrine-as-tests: hexScan (no palette literals outside tokens.css/
generated tokens.ts) + schemaDrift gate (scripts/dump-schemas.py AST
walk -> schema-snapshot.json -> every dataclass field mirrored in
types/api.ts; explicit shrink-only NOT_YET_MIRRORED debt list).
The drift gate caught real drift on first run: ChatTurnResult.turn_id
existed in Python, missing from TS — now mirrored.
Verified: build green; vitest 36 files / 279 tests EXIT=0; playwright
12/12; dump-schemas.py runs clean.
