Design doc for three coordinated harness fixes derived from the
2026-06-30-165708 session analysis: correct SKILL.md phase-advance
contract, fix the F6 cte_approved subject bug, and add a
tht-mediated schema_linking.json writer/validator.

All workstreams D, E, B, C, F, A, G done and pushed; resume cold-start stall
resolved (open-item #1). Refresh the Git section: main @ cbb8e18, the three
stale merged branches deleted, only main remains. Clean handoff snapshot.

Tier 1 (clean-room first-turn harness, harness/scripts/model-matrix.mjs):
kickoff + resume chain in-turn on ALL available models — zai/glm-5.2,
deepseek/deepseek-v4-{pro,flash}, aritmolab/qwen3.6-35b-a3b, zai/glm-4.5-air.
The resume cold-start stall recurs on none (closes A's cross-model robustness).
aritmolab/gemma4-26b-a4b is a 404 at the endpoint (listed but not served) — an
availability gap classified as MODEL_ERROR, not a workflow issue.
Tier 2 (live, baseline zai/glm-5.2): F single-select auto-confirm verified
end-to-end — answering the first reviewer_select persisted a concept_clarified
decision (review_decisions.jsonl 0->1) with no follow-up confirmation gate.
Closes F's deferred live check.
No prompt hardening needed. Results in the G plan doc + memory. Throwaway psd
sessions used and deleted; real sessions untouched.

Actionable scoping for the final workstream: a two-tier method (clean-room
first-turn harness generalised from the A2 repro-driver for cheap kickoff/resume
signals; sparing full Playwright F1 runs for the gate round-trip) over the
configured models (GLM 5.2 baseline, Deepseek V4, Qwen3.6, + breadth). Folds in
F's deferred single-select live check and A's resume-on-weaker-models check.

A1 — SessionMenu gains a Resume item, gated to status!=="finalized" && !archived
(matching the backend's 409 read-only guard), wired in AppShell to doResume ->
POST /sessions/:id/resume. SessionMenu.test.tsx (3 tests); frontend 96/96, tsc clean.
A2 — diagnosis-first clean-room repro driving `pi --mode rpc` with the backend's
exact resume handshake shows the cold-start stall NO LONGER reproduces on pi
0.79.4 (8/8 chained into `tht session show` + `read SKILL.md` in-turn, fresh and
partway sessions). The earlier narrate-and-stop predates the pi upgrade.
Defense-in-depth anyway: RIPRENDI_KICKOFF hardened to force the in-turn tool call
(gate_resume_kickoff.test.js + live regression 2/2). Gate JS 34/34.
PROJECT_STATE open-item #1 (resume stall) flipped to RESOLVED; cross-model resume
robustness folded into workstream G.

F — reviewer_select options may now carry a `decision` payload {type, subject,
detail?, rationale?} plus an optional `advance`. Picking such an option IS the
confirmation: the gate persists it directly (tht decision add) and optionally
advances, with no redundant reviewer_decide/reviewer_confirm follow-up gate.
Options without a payload stay ask-only; back/exit/Other never persist.
Pure logic extracted + exported for unit tests: resolveSelectOutcome (classifies
the response) and decisionAddArgs (shared with reviewer_decide, DRY). Gate JS
suite 33/33 (gate_select_decision.test.js, +5); harness pytest 269 unchanged.
Contract docs updated together: reviewer_select tool description, SKILL.md
(widget summary, disciplines 2-3, Phase-1 single-pick), and the CLAUDE.md gate
note. Live verification (model truly emits reviewer_select+decision, decision in
review_decisions.jsonl, no follow-up gate) deferred to workstream G — it is
model-behavior-dependent.

B — WorkflowBar renders F1..F8 as colored ring-dots (no phase-name text):
green=done, amber=running (subtle pulse), red=error, gray=pending; green
connectors lead the active dot, each dot carries data-state. Lightweight
error signal: sessionStore gains `phaseError`, set when an info event has
level=error during the active phase, cleared on the next ui_request.
C — denser single-line session rows (inline status dot + name, py-1), a
3-level type hierarchy (L1 SESSIONS / L2 section+group headers / L3 names),
and the "No group" label removed (ungrouped render after the last group,
guarded so the empty-state still teaches when there are zero groups).
Live-verified with Playwright (all four dot states, sidebar hierarchy, and
E's deferred activity-panel check). Frontend 93/93, tsc -b clean.

- CentralStatus: replace the red pulsing dot at the start of the "working" line
with the rotating WorkingSpinner, now a button that opens the model-activity
panel (onOpenActivity). WorkingSpinner is extracted to its own module (was
local to AppShell).
- ModelActivityPanel: show the last 5 lines of the model-stream tail (refreshing
as the stream grows) with an expand toggle to the full stream, replacing the
unbounded full transcript.
- AppShell: drop the separate spinner button (the inline icon is now the single
trigger) and the local WorkingSpinner def.
- Remove the now-orphaned Transcript.tsx (its only consumer was the panel).
TDD: CentralStatus + ModelActivityPanel tests RED->GREEN; frontend suite 87/87;
tsc clean. Live visual verification pending (to do with the B/C frontend pass).

New sessions get a concise Italian-keyword `name` instead of the truncated
question. `tht session new` (when no --name is given) derives it via a new
`_extract_name` helper using YAKE (pure-Python, unsupervised, Italian, no LLM),
dropping generic query verbs and keeping the top keywords in reading order;
falls back to `_summarize` if YAKE is unavailable. `create_session` core keeps
its `name=None` default — the policy lives at the CLI layer.
TDD: tests/test_session_name.py (unit + CliRunner integration). Full harness
suite 269 passed; ruff clean.

The frontend's reviewer widgets uniformly send the picked option in a `choices`
array (SelectWidget/ArtifactGateWidget: `choices: [optionId]`), but the gate's
reviewer_select and reviewer_confirm(reject) handlers read `resp.choice`
(singular). Result: every single-select gate saw an undefined choice, answered
"Nessuna scelta ricevuta", and re-presented forever — the workflow could never
pass F1. (reviewer_decide/multiselect already read `resp.choices`, so it worked.)
Add a shared selectedChoice(resp) helper reading choices[0] (falling back to the
legacy singular choice); both handlers use it.
TDD: gate/__tests__/gate_choice.test.js RED->GREEN; full gate suite 28/28.
Verified LIVE (Playwright -> real Pi -> GLM 5.2): a single-select F1 answer is
now accepted and the workflow advances (clarification 2/4 -> 3/4). The same run
also live-verified the F1 hang fix (418187a).

ctx.ui.input in `pi --mode rpc` correlates extension_ui_response on its own
top-level RPC id (crypto.randomUUID), not the descriptor id the gate carries
in `title`. SessionBridge replied with the descriptor id, so Pi silently
dropped the response and the model never resumed — every reviewer widget hung
after the human answered.
SessionBridge now stores Pi's top-level m.id (pendingPiId) and replies
extension_ui_response{ id: pendingPiId, value: <uiResponse> }; value still
carries the descriptor id so the gate's internal resp.id === descriptor.id
check still holds.
The fake-pi double had masked the bug by forcing m.id == descriptor.id; it now
mirrors real Pi (distinct randomUUID, correlate on it, drop unknown ids), with
a negative regression test. SKILL.md Phase 1 also now steers multi-answer
disambiguation to reviewer_decide (multiselect).
Tests: backend 67/67, tsc clean, fake-pi contract 2/2.

While the model works (active session, no pending widget), CentralStatus shows
a Claude-Code-style live status: a pulsing dot, elapsed seconds (ticking), and a
short tail of the model's current output — so the centre no longer looks stuck
during the long F1 loop. Verbose stream stays in the left panel. No tokens yet
(would need the SessionBridge to forward Pi usage).

Active/Archive accordions; rename group (client-side reassign); central
area shows only last user entry + gate notify/info + active widget; the
verbose model stream moves to a left on-demand panel toggled by the WIP
icon (moved above the composer). Frontend-only; fine thinking-separation
deferred.

pi 0.73 rpc mode is headless and runs tools without an approval gate; the
removed --approve flag made pi exit with 'Unknown option: --approve', breaking
every session spawn. Spawn args are now just --mode rpc. +regression test.

- SessionMenu: anglicize all Italian labels (Vista divisa → Split view, etc.)
- RenameDialog: add empty-name guard + change title to "Rename session"
- DeleteConfirmDialog: translate title and description to English
- SessionActions.test: add 2 new tests (empty name guard, cancel on DeleteConfirmDialog)

Add the SKILL.md design contract (persisted state is the truth) and a
dedicated Resume correctness section: backend new/resume prompt mode,
missing cold-start procedure in the skill, end-to-end verification gate.

- Remove the microphone icon from the composer footer
- Left: workspace selector in its place
- Right: model + thinking-level selectors (persist via PUT /settings) next to
the context-usage gauge
- Delete the Settings dialog (form + button); only "New session" remains
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
- loadEnvFromDotenv: read ctx.cwd/.env into the process environment
- prepareReviewerArguments: normalize/parse reviewer tool inputs
- tidy reserved-option filtering and tht command argument assembly

- Center ThothII logo + tagline; break "Human In The Loop" onto a second line
- Rename "New question" → "New session"; the button now clears the screen and
focuses the sticky bottom composer instead of opening a dialog
- Composer is always rendered and pinned at the bottom; typing the first
message there creates the session (no modal)
- Add inline stop control (square + inner circle) that interrupts and saves
the session via /close
- Always-present send affordance (CornerDownLeft ↵) on the right of the box
- Status footer under the box: mic (inert), model name, thinking level, and a
context-usage gauge (placeholder)
- Brand-tinted spinner beside the logo while the harness/backend holds the
ball; hidden once a widget needs human input

The interface is now fully English regardless of the chat language (session
titles stay in whatever language the user typed). Changed the right-rail
subtitle to 'Datamart Builder with Human In The Loop'. Translated all chrome:
new-question/settings dialogs, workflow phase strip (F1-F8), session rail,
steer input, widgets (select/multiselect/freetext/fallback/reserved controls)
and viewers (SQL, results, schema linking). Test matchers updated in lockstep.

Body-less POSTs (resume, close) sent content-type: application/json with no
body, so Fastify rejected them with FST_ERR_CTP_EMPTY_JSON_BODY (400) and
clicking an existing session never reopened it. apiFetch now adds the header
only when init.body is set.

Adopt the portal's design language so the app embeds seamlessly into its
header/sidebar chrome later:
- Token layer rewritten as raw OKLCH triplets (the previous oklch()-wrapped
vars produced invalid colors; the UI was effectively unstyled). Values mirror
GSD: Manrope + Fraunces fonts, #cb333b red brand, warm off-white surfaces,
pill buttons, brand focus rings. Dark tokens follow .dark or the portal's
[data-bs-theme=dark].
- Layout: no left sidebar, no header (the portal supplies them). Conversation
column flush-left with a slim F1-F8 phase strip; session rail moved to the
RIGHT, mirroring the portal's left sidebar (red section label, red-tint active
item). Editorial empty state.
- Transcript component now actually renders the streamed assistant turns (the
store accumulated them but nothing displayed them). Toaster mounted for errors
(matchMedia polyfill added to the jsdom test setup).

Found via live browser test: PUT /settings preflight was rejected because
@fastify/cors default methods omit PUT. GET/POST were unaffected.

Removes workspace/model/provider/thinking fields. Dialog now posts only { question } to createSession and calls onCreated on success.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
workspace/provider/model/thinking now come from getSettings() injected into
sessionRoutes; the request body supplies only question+name. Also teaches
fake_pi_rpc to respond to set_model and set_thinking_level RPC commands so
tests that pass real model settings don't hang.

Live end-to-end against real pi --mode rpc revealed Pi streams assistant text as
top-level message_update events whose nested assistantMessageEvent carries the
incremental delta — not the top-level text_delta the fake-pi-rpc emits. The bridge
now maps message_update(assistantMessageEvent.text_delta).delta -> FE text_delta,
so the chat shows the model's output during a real session.

Live end-to-end surfaced a 500 on every tht call: ThtRunner prepended
'-c <config>' before the subcommand, but tht has no global -c option
('No such option: -c'). --config/-c is a per-command option, so it must be
appended AFTER the subcommand. Extracted buildArgv() and fixed the unit test
that had codified the wrong (prepended) order.

- sessionStore.applyEvent: on ui_request set currentPhase normalized from the
descriptor's phase to its short id (e.g. "F4_schema_linking" -> "F4"), so
WorkflowBar actually highlights the active phase; falls back to the existing
phase when the descriptor has none. setPhase kept for resume/getSession.
- Add pushToast store action; WidgetHost wraps postResponse in try/catch,
pushes an error toast and keeps the widget pending on failure (clearPending
only on success) so the user can retry.
- Tests: store currentPhase normalization + no-phase passthrough + pushToast;
new WorkflowBar.test.tsx asserting the matching phase is highlighted.

FakeEventSource.addEventListener was a no-op, so emit() only drove onmessage.
Production relies on addEventListener for the backend's NAMED events
(event: ui_request), so the unit tests could pass while prod silently broke.
- fakeEventSource: store named handlers in a Map<string,Set>; add emitNamed()
that dispatches to them; keep emit() for the unnamed/default onmessage path
- useSessionStream.test: ui_request now driven via emitNamed (production path);
add a separate test for the unnamed text_delta path via plain emit
- f1-loop.test: widget emission switched to emitNamed("ui_request", ...)
- verified: tests FAIL if addEventListener wiring is removed from
useSessionStream (then restored)
- cleanup: fake-pi.mjs drops unused execFileSync import, uses static spawnSync

Adds a real-browser Playwright e2e of the full F1 disambiguation loop,
driven against the real backend + fake binaries (no VPN, no real Pi, no Python).
- frontend/e2e/fixtures/fake-tht.mjs: stubs tht CLI (session new/list/show)
- frontend/e2e/fixtures/fake-pi.mjs: wraps harness fake-pi-rpc with f1_disambiguation.json
- frontend/playwright.config.ts: two webServer entries (backend:8799, frontend:5199)
- frontend/e2e/f1.spec.ts: open app → create session → wait for SelectWidget → respond
Bug fixes discovered during e2e:
- useSessionStream: add addEventListener for named SSE events (backend sends
'event: ui_request' etc.; onmessage only fires for unnamed 'event: message')
- FakeEventSource: add no-op addEventListener/removeEventListener stubs
- backend SSE route: add CORS headers manually in writeHead() since
reply.raw bypasses the @fastify/cors onSend hook
- backend: install and register @fastify/cors for all non-SSE routes

- Add NewSessionDialog.test.tsx covering §9 graceful degradation:
empty models -> free-text input; non-empty models -> dropdown; plus a
createSession body-keys assertion
- Normalize model entries to {value,label} so object-shaped models
({provider,id}) render correctly in the dropdown (was assuming strings)
- NavSessions: invalidate the ["sessions"] query after a successful
resumeSession so the list/status refreshes immediately
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
- NavSessions: left nav listing sessions via listSessions (TanStack Query),
clicking resumes via resumeSession and sets active; active item highlighted
- NewSessionDialog: ShadCn dialog with question textarea, workspace native
select (from listWorkspaces), graceful model field (dropdown when models
list is non-empty, free-text input when empty per §9 degradation),
optional thinking/provider fields; try/catch surfaces errors inline
- SteerInput: text input + button POSTs to postSteer, clears on send,
supports Enter key; only shown when a session is active
- WorkflowBar: renders 8 phases (F1..F8) with data-active highlighting
driven by useSessionStore.currentPhase (new store field + setPhase action)
- AppShell: wires all four components; right artifact sidebar now collapsible
via a toggle button (useState sidebarOpen); replaces old "Nuova domanda"
button with NewSessionDialog trigger
- f1-loop.test: updated to drive through the new dialog flow (open → fill
question → submit → wait for SSE → respond)

Test (a) now drains pending highlightSql microtasks inside act() via

TDD: SqlViewer renders collapsible CTE blocks with name/field-count/
test-status badges, shiki-highlighted SQL body (dangerouslySetInnerHTML),
per-field comments, and a vertical/horizontal layout toggle.
highlight.ts wraps shiki as a lazy singleton; tests mock it for
determinism (pattern mirrors mermaid.ts).
