Antigravity terminal structured interview picker

Original request (verbatim): "Close the gap between Claude, Codex, Antigravity and Pi. More universal code, less provider specific" Settled inputs: PRD (Task 9932) and Architecture (Task 9933) of this epic. Approach (architecture §1): lifecycle events run in Jaah-owned code in front of every session (ACP: `jaah-acp-host`, `apps/jaahd/acp/host.py`; terminal: node daemon + vendor CLI events); tool events run in-band through ONE neutral dispatcher `tools/hook_bridge_core.py::dispatch`. Adapters contribute only declarations (event names, tool-name map, placement literals, error text patterns, question prefix), never a copy of the logic. Requirement R1 (verbatim): "Each of these mechanisms has exactly ONE provider-neutral implementation home that every provider uses; an adapter contributes only vendor literals and capability declarations, never its own copy of the logic: (a) hook/guard rendering & chaining, (b) hook-context injection into the model, (c) charter placement as system/built-in instructions, (d) session-start rule list (guard brief), (e) read-once guard reset signal, (f) prompt-submit and session-end lifecycle events, (g) StopFailure / API-error self-heal, (h) project-memory hooks, (i) token/cost (spend) reading, (j) usage-window (quota) reading, (k) the operator question / structured interview channel." R5 (verbatim): "Availability: every closed capability is ON by default on the dev control plane (`dev.jaah.ai`) — no new switch that ships OFF; if a switch is unavoidable it defaults ON and is wired in the real deployment." Closing-test naming contract (architecture §4): every degradation key this child closes gets a test named `test_closes_<key with - as _>` (e.g. `test_closes_no_hook_context`); C9 refuses to remove a key without it. Do NOT remove catalogue degradation keys in this child — the close-out child removes them; this child delivers the behaviour and the closing test. ## Scope (this child) PRECONDITION / HOLD (architecture §4, human precondition I4 — the AskUserQuestion pause below IS the hold): this child measures a live agy 1.2.11 *terminal* session in a scratch `agy1` console session opened through the console on dev (`https://app.dev.jaah.ai`). First check the dev Accounts page: if `agy1` is not "available", raise ONE AskUserQuestion round (header `Human act`) asking the operator to re-login `agy1` on dev; do every unblocked part (code, declarations, fixture scaffolding) meanwhile. If the answer does not clear it, deliver what is not blocked and settle naming the unmeasured remainder — never declare unmeasured literals. Architecture child C3b — closes Antigravity `no-structured-interview` (PRD "Operator interaction"; mechanism (k), home: the `task.question` verb → `apps/api/app/routes/agent/task_terminal.py::create_task_question`; terminal entry points `tools/capture_askuserquestion.py` + `apps/jaahd/answer_delivery.py`). - Measure agy 1.2.11's `ask_question` picker in a scratch `agy1` console session: its rendered prompt, option layout and the keys that select one. Record the pane as a fixture. - Declare those literals on the Antigravity adapter's `ComposerTui` (declarations only — no Antigravity-specific capture/delivery logic). - Stop the bridge refusing `ask_question` and let the existing question capture and `answer_delivery` path file and answer it. - Set `can_interview=True` on the Antigravity row (`apps/jaahd/agent_providers.py` ANTIGRAVITY). PRD AC10 (verbatim): "a Task with Autonomous OFF on an Antigravity terminal session and on Pi asks through the structured question card (console shows the question with options, answering returns it to the same session), not a shell command/prose." The live Antigravity-terminal half of AC10 belongs to the Finish stage once `agy1` is re-logged (architecture §8). Credentials & reach: - C3a/C3b terminal measurements + AC7/AC10 Antigravity terminal (live half) | dev account `agy1` (Google sign-in; Accounts page shows "Needs attention: Login") | **deferred**: the login is an operator action (I4: "I'll re-login both"). C3a/C3b are held until `agy1` shows available (their measurements need it); the Finish stage then runs the live checks - C1–C7 unit and replay tests, AC1–AC4 | nothing beyond the worktree (`./dc check full`) | verified (worktree) - Console (Accounts page check, scratch `agy1` console session): AC5, AC9, AC11 browser checks | `org/console/dev-login` (on roster, `credential_get` ok; its `base_url` field is stale, so use `https://app.dev.jaah.ai`) on dev | verified (probe: GET / → 200; Accounts page read in browser) Out of scope (PRD, verbatim — do NOT touch): - MUST NOT retire, rewrite or change the runtime selection of the legacy terminal runtime; Claude `oauth` stays `legacy_only` (ADR in `docs/adrs/README.md`, ACP Claude entry). - MUST NOT remove or reword any "stay published" degradation (list above), including Pi `no-subagents` and `acp-runtime-only`. - MUST NOT build Pi subagents or a Jaah-side subagent lane. - MUST NOT add Jaah-side workarounds for vendor-intrinsic DeepSeek/Codex gaps (PDF conversion, model remap changes, throttling avoidance). - MUST NOT do live-verification work for Antigravity `not-yet-observed`, nor touch `home-is-account-dir` or `microvm-signed-in-legacy-runtime`. - MUST NOT change `tools/provider_branches.toml` patterns/allowlist scope beyond what removing branches requires (gate tightening was not selected), and set no line-count target. - MUST NOT add a new provider or retire one; no change to login/sign-in flows, model-tier resolution, or the plan gate (`non_claude_engines`). Stay-published keys (must stay byte-identical): DeepSeek `document-blocks-unsupported`, `images-flash-only`, `prompt-cache-controls-ignored`, `beta-features-ignored`, `web-search-extra-calls`, `claude-model-names-remapped`, `model-quality-differs`; Codex `device-code-login-workspace-gated`, `subscription-concurrency-throttling`; Pi `no-subagents`, `acp-runtime-only`. I1-escaped (stay, unchanged): Antigravity `no-spend-reading`; Pi and DeepSeek `no-quota-reading`. Done means: - A pane-fixture test drives the RECORDED agy 1.2.11 picker (real measured pane, not a synthetic one) to the chosen option — cite test output. - Capture files exactly one operator round for an `ask_question` call — cite test output. - `test_closes_no_structured_interview` exists and passes (`grep -rn test_closes_no_structured_interview`). - `can_interview=True` on the Antigravity row; Claude/Codex question paths unchanged (their existing tests green). - `python3 tools/check_provider_branches.py` exits 0; quick gate green. - (deferred — live Antigravity terminal AC10 needs `agy1` re-login; runs in the Finish stage)
