merge: hotfix/fresh-box-experience → main (v0.3.5 fresh-box experience)

Fixes the v0.3.4 fresh-box failures: silent CLI under bare-word PATH
invocation (SEA argv detection), bootstrap dying on venv creation without an
actionable hint (poisoned-partial-venv recovery + apt hint + doctor
venv-capability probe + preflight), installer falsely 'verifying' a silent
binary, and localhost-only server binding (network mode: 0.0.0.0 + wildcard
CORS + hostname-derived API URL — remote browsing zero-config).

38 CLI tests, 3 web tests, 409 ai-service tests green; build/typecheck/lint
clean.

 **v0.3 additions (Credential Engines):** real credential engines replace v0.2 mock inputs — a sandbox fabric (isolated per-learner coding environments via Linux user/mount/pid/net namespaces), a live build-telemetry pipeline (WebSocket ingest + SQLite-ordered event log), a process-trace grading engine, seeded per-learner variant task generation, and a voice-based oral defense (STT/TTS via a new provider-agnostic voice layer). **First real persistence introduced: SQLite** (`ai_service/telemetry/`, grading, variant, defense stores).

+**v0.4 additions (Distribution & Bootstrap CLI, founder directive D-016):** a new `apps/cli` package — the `nextcraft` bootstrap CLI (`doctor`/`bootstrap`/`verify`/`dev`) compiled to a self-contained linux x64 binary via **Node SEA** (probe-verified: Go/Rust absent, node v24.15.0 SEA-capable), installed by a repo-served one-liner script that resolves the latest Gitea release, downloads binary + sha256 sidecar, verifies, and installs to `~/.local/bin`. Every release from v0.4 onward attaches the binary + checksum as release assets (the "ongoing binaries" requirement). The CLI is a thin wrapper: all orchestration logic stays in `apps/ai-service/scripts/` (bootstrap.sh/dev.sh) — the CLI composes them via subprocess (A-202), duplicating nothing. Previously-planned v0.4 seams (real STT/TTS, KYC, design/sim envs, seq-lease) move to v0.5.

+18. **D-033 Binary toolchain = Node SEA (probe-verified)** — Go and Rust are absent from this box; node v24.15.0 ships SEA support (`--experimental-sea-config`, postject-free on linux via `cp node nextcraft && node sea-config` … blob injection with the system `dd`/`npx postject` if needed). CLI source lives in `apps/cli` (TypeScript, compiled to a single CJS bundle by esbuild, then SEA-injected into a copy of the node binary → `nextcraft-linux-x64`). Fallback if SEA breaks: python3 `zipapp` (3.11.2 available). No new toolchain deps beyond dev-scoped esbuild.
+19. **D-034 CLI = thin wrapper, orchestration stays in scripts/** — `nextcraft` composes `apps/ai-service/scripts/bootstrap.sh` and `scripts/dev.sh` equivalents via `spawn` with inherited stdio and timeout guards (A-202/A-209). doctor/bootstrap/verify implement only *checking* logic (prereqs, env template, health) — never re-implement installs. This keeps one source of truth for bootstrap semantics.
+20. **D-035 Install path = repo raw `install.sh` + Gitea latest-release API** — the one-liner `curl -fsSL <forge>/coreci/nextcraft/raw/main/scripts/install.sh | bash` resolves `GET /api/v1/repos/coreci/nextcraft/releases/latest`, downloads the `nextcraft-linux-x64` + `nextcraft-linux-x64.sha256` assets, verifies sha256 (`shasum -a 256`), installs to `~/.local/bin` (PATH hint), and degrades to printed source-bootstrap instructions when no binary asset exists or the platform mismatches (A-203/A-204/A-206).
+21. **D-036 Ongoing binaries = ship-workflow asset step** — the release pipeline (v0.3's `ShipWorkflow.createRelease` equivalent, executed as the ship step's asset stage) builds the binary + checksum and attaches both to every Gitea release from v0.4 onward (A-205). Token resolution stays `.env*`-only (D-006/D-014); binaries are linux x64 only for v0.4 (macOS arm64 deferred — unverifiable on this box).
+22. **D-037 CLI package layout** — `apps/cli` is a pnpm workspace package (`@nextcraft/cli`): `src/` (entry, commands/, checks/, lib/), `scripts/build-binary.mjs` (esbuild bundle → SEA inject), unit tests runnable via `pnpm --filter @nextcraft/cli test` (node:test, no new test framework). Root `package.json` gains `cli:*` passthrough scripts mirroring the `ai:*` pattern (D-022).
+23. **D-038 Network mode (v0.3.5)** — dev binds 0.0.0.0 (`AI_HOST`, default 0.0.0.0, revert via 127.0.0.1); CORS + WS-origin gates read `AI_CORS_ORIGINS` (default `*` — any origin, safe only because credentials are never enabled; explicit comma list restricts); the web client derives the API base URL from the browser hostname at runtime (`engine-base-url.ts`: `NEXT_PUBLIC_AI_SERVICE_URL` override → `http://${window.location.hostname}:8420` → `localhost` server-side). Hotfix also fixes: SEA direct-run detection (`require("node:sea").isSea()` — argv shape differs by invocation style), installer honesty gate (silent `--version` = hard fail), bootstrap venv recovery (poisoned partial `.venv` removal + distro-specific `apt install python3.XX-venv` hint), and doctor venv-capability probe with bootstrap preflight.

 ### v0.3 Architecture Decisions (from Research — Credential Engines)
 
 9. **D-024 Sandbox isolation = Linux namespaces via `unshare`** — per-learner sandbox runs as a subprocess entered into fresh user+mount+pid+network namespaces (`unshare --user --map-root-user --mount --pid --fork --net`). Probe-verified on this box: in-namespace uid=0, **network fully isolated** (0 interfaces), learner writes land in a per-sandbox directory; proc-remount not permitted here but not required. Chosen because no container runtime (docker/podman/bwrap/firejail) exists on the box and there is no sudo. A `SandboxBackend` protocol abstracts the spawner so a future containerd/runc backend can replace namespace-spawning without touching callers.

+# Nextcraft v0.4 — GRILL.md (Adversarial Review Verdict)
+
+**Stage:** GRILL, Phase 0 pre-execution · **Verdict:** GO-WITH-CHANGES · **Confidence:** 0.83
+
+## Summary
+
+The distribution milestone is small, founder-directed (D-016, confidence 0.99), and additive (zero changes to the running credential pipeline). The plan's central risk: **Node SEA was probe-verified as a flag, not as a working build** — the v0.3 lesson (A-101: probe the mechanism, not the existence) applies. Second gap: a binary whose `--version` lies (stale package.json) would poison the "ongoing binaries" contract. Third: sed-based JSON parsing in install.sh is a fragility + integrity risk. Fourth: "ongoing binaries" has no enforcement mechanism beyond prose. All four closed by binding decisions G-101..G-104 below. No scope cuts required — the milestone is already minimal.
+
+## Per-Axis Findings
+
+| Axis | Verdict | Rationale |
+|------|---------|-----------|
+| Business case | PASS | Founder directive explicit + recorded (D-016). Evidence of need: live Gitea probe shows latest release v0.2.8 with ZERO assets; bootstrap requires repo archaeology (scripts found only via package.json spelunking). |
+| Scope | PASS | 5 REQs, 3 execution phases, one focused surface (apps/cli + scripts). Smallest milestone yet. macOS arm64 already cut (D-036, unverifiable here). |
+| Feasibility | CONCERN (fixed) | SEA flag exists on node v24.15.0, but no end-to-end SEA binary was built during RESEARCH. postject availability assumed (`npx postject` — needs npm registry reachability, unproven). Zipapp fallback requires python3 on target — an honest-degradation ladder, not a silent downgrade. → G-101. |
+| Honest versioning | CONCERN (fixed) | `--version` from package.json would print a stale hardcoded version inside a per-release binary — breaks upgrade detection + the one-liner's re-run-to-upgrade promise. → G-102. |
+| Install integrity | CONCERN (fixed) | sed/grep JSON parsing is brittle; a parse failure must never fall through to installing an unverified artifact. Exact asset-name matching + hard-degrade to source instructions. → G-103. |
+| Sequencing | PASS | P1 CLI (source-runnable) → P2 binary+pipeline → P3 docs+E2E matches dependency order; each phase ships independently. |
+| Cost/quota | PASS | Zero new paid infra; binaries built on-box; Gitea releases free. Dev-only esbuild dep. |
+| Risks | CONCERN (fixed) | Top 3: SEA end-to-end (→ G-101 live probe FIRST in P2), npm registry reachability for esbuild (→ proven by P1's pnpm install must-have), Gitea asset-upload token scope (→ live-proven at the v0.3.2 ship itself). |
+| Adoption/operability | PASS | Consumer = founder + future pilots; one command replaces README archaeology. Rollback trivial (rm ~/.local/bin/nextcraft). No server changes. |
+
+## Binding Decisions (applied to PLAN.md)
+
+- **G-101 (BINDING) — SEA live-build probe is the FIRST P2 action.** Task 2-1-01 builds a real binary before anything depends on it; the build script encodes the fallback ladder explicitly (SEA → zipapp with "requires python3" honesty). If SEA fails on this box, zipapp becomes primary with the docs stating the requirement — no silent claim of node-less operation.
+- **G-102 (BINDING) — Version stamping at build time.** `build-binary` accepts the shipping tag and stamps it into the bundle (`NEXTCRAFT_VERSION` replace); `--version` prints it; install E2E asserts the installed binary reports the tag it was downloaded from. A binary may never report a version it was not built as.
+- **G-103 (BINDING) — Install-script integrity hard-degrade.** install.sh matches assets by EXACT name (`nextcraft-linux-x64`, `nextcraft-linux-x64.sha256`); any parse/lookup/download failure degrades to source-bootstrap instructions (exit 0) — never installs unverified or name-approximate artifacts. Checksum mismatch = hard stop, exit 1, explicit do-not-run message. dash-safe POSIX sh, no jq.
+- **G-104 (BINDING) — Ongoing-binaries enforcement.** Every ship from v0.3.2 onward MUST run `scripts/release-assets.sh <tag>` after tag+merge (best-effort, non-blocking, `release_pending` escalation on failure — but attempted + logged every release). The final-phase audit gate includes "milestone release carries both assets" as a check. This makes the founder's "ongoing binaries" directive a pipeline property, not prose.
+
+## Escalations
+
+None. All four concerns resolved at confidence ≥ 0.85. No axis requires founder escalation (directive already explicit).
+
+## Outcome
+
+**GO** — G-101..G-104 applied to PLAN.md before Phase 1 execution. The milestone claims only what its probes prove, and the ongoing-binaries contract has an enforcement mechanism.

-| frontend-engineer vs design-system-engineer (packages/ui) | design-system-engineer owns design tokens and primitive components (terminal frame, mic control, grade badge); frontend-engineer owns composite components and page-level UI. |
-| ai-engineer vs backend-engineer (grading/variants) | ai-engineer owns the model-facing files (features/engine/templates/generator = LLM logic + prompts); backend-engineer owns the persistence stores + API endpoints. Boundary: stores are pure SQLite; engine logic is pure compute. |
-| sandbox-engineer vs backend-engineer (sandbox/) | sandbox-engineer owns `ai_service/sandbox/**` + capture agent; backend-engineer owns the API route that composes `sandbox/manager.py` via DI. manager.py has a narrow typed interface consumed by api/. |
-| voice-engineer vs ai-engineer (Examiner agent) | ai-engineer owns `agents/examiner.py` + its prompt; voice-engineer owns `voice/**` (audio in/out). Examiner calls `voice/` through the `VoiceProvider` protocol — never imports concrete providers. |
-| ai-engineer vs data-engineer (mock duplication) | ai-engineer owns `ai_service/corpus/` (Python); data-engineer owns `packages/mock-data` (TS). Shared IDs/shapes aligned by convention (D-021). |
-| lead-developer vs any | lead-developer coordinates only, does not directly modify code files. |
+| cli-engineer vs backend-engineer (scripts/) | backend-engineer owns `apps/ai-service/scripts/**` + root `package.json`/`turbo.json` wiring; cli-engineer owns `apps/cli/**` + top-level `scripts/install.sh` + `scripts/release-assets.sh` and *consumes* backend scripts via spawn — never edits them |

 ## Overview
 
-This plan covers execution phases 1-6 of milestone v0.3 (Credential Engines): the real engines that replace v0.2's mock inputs — a namespace-isolated sandbox fabric, live build telemetry over WebSocket + SQLite, a process-trace grading engine, seeded per-learner variant task generation, and an oral/voice defense with a seventh Examiner agent — plus re-grounding the Lab/Assessor/Proctor agents onto real engine inputs and wiring the v0.1 learner surfaces to the real build/defense/grading paths. Phases are strictly sequential (P1→P6); within each phase, Wave 1 tasks are parallelizable (no cross-file dependencies) and later waves depend on earlier ones.
+This plan covers execution phases 1–3 of milestone v0.4 (Distribution & Bootstrap CLI) plus the final phase (P4 review+ship). The milestone delivers the founder directive (D-016): a streamlined install for Nextcraft — a `nextcraft` bootstrap CLI shipped as a linux x64 binary, installed via a one-liner script, with binaries published on **every ongoing release** from v0.4 onward. Phases are strictly sequential (P1→P3); within each phase, Wave 1 tasks are parallelizable (no cross-file dependencies) and later waves depend on earlier ones.
 
-**Environment facts (apply throughout):** Python 3.11.2 via `python3 -m venv` (no uv, no system pip); pnpm 12.3.4 via corepack; turborepo; ai-service port **8420**; default model `gemma4:31b` (config via `AI_TUTOR_MODEL`); ollama-cloud base `https://ollama.com/v1` (OpenAI-compatible, Bearer auth); keys live only in gitignored `.ciagent/.env.secrets` (exported by `scripts/dev.sh`) — never in code, commits, or logs; all automated tests use the deterministic mock LLM and mock voice providers and **never call cloud or voice APIs**. New ai-service deps this milestone: `sqlmodel`, `sqlalchemy`, `websockets`, `aiofiles` (all PyPI-verified; added in Task 1-1-02). SQLite data (`apps/ai-service/ai_service/data/`) and sandbox dirs (`apps/ai-service/sandboxes/`) are already gitignored. **KYC/age-gating is deferred per founder directive (A-110)** — no identity work; age-gating stays the v0.1 visual flow mockup. **GRILL scope decisions (this revision):** real server STT/TTS (`OpenAIAudioProvider`) deferred to v0.4 — voice defense is mock+browser-first (CUT-1/G-7); the interactive xterm.js shell relay is deferred to v0.4 — the build panel is run/test-buttons + read-only exec output (CUT-2/G-8), so `@xterm/*` is NOT a v0.3 dependency; sandbox abuse control (per-learner caps + allowlist, G-5) ships even though KYC is deferred; sandbox resource limits are partially enforced (memory/CPU/wall-clock + workdir-size sweep; per-sandbox pids and hard disk quota are accepted gaps, G-1/G-2).
+**Environment facts (probe-verified, apply throughout):** Go MISSING, Rust MISSING, gcc 12.2 present, **node v24.15.0 x64 linux (SEA-capable)**, python3 3.11.2, `shasum` 6.02, pnpm 12.3.4 via corepack, turborepo 2.3.3, tsx 4.23 in root devDeps path. Gitea API verified live at `https://git.coreci.dev/api/v1` (latest release v0.2.8, **zero assets** — the gap this milestone closes). Existing orchestration: `apps/ai-service/scripts/bootstrap.sh` (idempotent venv+pip incl. the no-ensurepip get-pip path), `apps/ai-service/scripts/dev.sh` (secrets export → uvicorn :8420), `apps/ai-service/.env.example` (full AI_* template). Root scripts: `ai:dev/ai:test/ai:bootstrap/ai:lint` turbo passthroughs (D-022 pattern to mirror as `cli:*`). Secrets live only in gitignored `.ciagent/.env.secrets` (GITEA_TOKEN, OLLAMA_API_KEY, OLLAMA_BASE_URL) — never in code, commits, or logs; tests never call the cloud or the forge (mocks/fixtures only).
+
+**Milestone type:** feature. Tags: phase 0 → **v0.3.0**, P1 → v0.3.1, P2 → v0.3.2, P3 → v0.3.3, final phase P4 → **v0.3.4 = milestone release**. **GRILL binding decisions (this revision):** G-101 — SEA live-build probe is the FIRST P2 action (mechanism, not flag, must be proven); fallback ladder encoded honestly (zipapp requires python3 on target). G-102 — binary `--version` stamped from the shipping tag at build time (never a stale package.json version); install E2E asserts the installed binary reports its release tag. G-103 — install.sh matches assets by exact name; any parse/download failure degrades to source-bootstrap instructions (exit 0), never installs unverified artifacts; checksum mismatch = hard stop exit 1. G-104 — every ship from v0.3.2 onward runs `scripts/release-assets.sh <tag>` (best-effort, logged, non-blocking); the P4 audit gate checks the milestone release carries both assets.

-## Phase 1: Sandbox Fabric
-
-**Requirements:** REQ-3-001, REQ-3-002
-**Goal:** `SandboxBackend` protocol + `unshare`-based namespace spawner (D-024) + lifecycle manager with concurrency guard (D-032) + per-sandbox workdir; isolation and resources probe-verified on this box; `/v1/sandboxes` API live; deps + gitignore landed
-
-### Wave 1: Foundations (parallel — no shared files)
-
-#### Task 1-1-01: SandboxBackend protocol + unshare spawner + probe test
-- **Persona:** sandbox-engineer — **REQ:** REQ-3-001, REQ-3-002
-- **Files:** `apps/ai-service/ai_service/sandbox/__init__.py`, `apps/ai-service/ai_service/sandbox/backend.py`, `apps/ai-service/ai_service/sandbox/workdir.py`, `apps/ai-service/ai_service/sandbox/unshare_backend.py`, `apps/ai-service/tests/sandbox/__init__.py`, `apps/ai-service/tests/sandbox/test_isolation.py`
-- **Action:** `backend.py`: `SandboxBackend` protocol + `SandboxSpec` (sandbox_id, learner_id, workdir, resource limits) + `SandboxHandle` (id, pid, workdir, created_at); `spawn(spec)`, `exec(handle, cmd)`, `snapshot(handle) -> Path`, `destroy(handle)`. `workdir.py`: per-sandbox layout under `apps/ai-service/sandboxes/<id>/` (workspace/ writable, snapshot() = recursive copy to `snapshots/<ts>/`) — no symlinks as the snapshot mechanism. `unshare_backend.py`: subprocess spawner — `unshare --user --map-root-user --mount --pid --fork --net` with the per-sandbox dir bind-mounted (`--bind <dir> /work`) and `chdir /work` (D-024); pipes for stdout/stderr; async wrappers. `test_isolation.py` — **re-verify box isolation properties (runs on this box, guarded by probe skip):** (a) `id -u` inside namespace prints `0`; (b) `ip link` inside namespace shows 0 usable interfaces (loopback-only/no carrier) — network isolated; (c) file written to `/work/inside.txt` lands at `sandboxes/<id>/workspace/inside.txt` on the host; (d) attempt to write outside the mount (e.g. host tmp path via bind) does not escape the per-sandbox dir; (e) `/proc` visibility degraded (proc-remount not permitted per A-101 — assert the probe documents this, not that it fails).
-- **Verify:** `pnpm ai:test` — `tests/sandbox/test_isolation.py` green on this box (probe-gated: skips with an explicit reason if userns unavailable); `lint` clean
-
-#### Task 1-1-02: v0.3 dependencies + gitignore + config additions
-- **Persona:** backend-engineer — **REQ:** REQ-3-001
-- **Files:** `apps/ai-service/pyproject.toml` (update), `apps/ai-service/ai_service/config.py` (update), `apps/ai-service/.env.example` (update), `apps/ai-service/scripts/bootstrap.sh` (update if needed), root `package.json` (no change), `turbo.json` (no change)
-- **Action:** Add pinned deps: `sqlmodel`, `sqlalchemy`, `websockets`, `aiofiles` to pyproject. `config.py` additions (env_prefix `AI_`): `AI_SANDBOX_DIR` (default `apps/ai-service/sandboxes`), `AI_SANDBOX_MAX_CONCURRENT` (default 5, D-032), `AI_SANDBOX_CPU_LIMIT` (default 1 core / cpu.max), `AI_SANDBOX_MEM_LIMIT_MB` (default 512), `AI_SANDBOX_PIDS_LIMIT` (default 256), `AI_SANDBOX_TIMEOUT_S` (default 1800), `AI_DB_PATH` (default `ai_service/data/nextcraft.db`), `AI_VOICE_BASE_URL` / `AI_VOICE_API_KEY` / `AI_VOICE_STT_MODEL` / `AI_VOICE_TTS_MODEL` (all **optional**, default empty — mock-first, D-030; documented in `.env.example` and README). Confirm `.gitignore` already covers `ai_service/data/` + `sandboxes/` (it does — v0.3 block present). Re-run bootstrap idempotently to install new deps.
-- **Verify:** `pnpm ai:bootstrap` re-installs cleanly (no-op venv, new wheels land); `python -c "import sqlmodel, sqlalchemy, websockets, aiofiles"` succeeds in the venv; settings parse with new keys unset
-
-#### Task 1-1-03: Resource-limit probe documentation + harness ruff pass
-- **Persona:** ai-engineer — **REQ:** REQ-3-001
-- **Files:** `apps/ai-service/README.md` (update: sandbox section + probe transcript), `apps/ai-service/pyproject.toml` (no change), `apps/ai-service/tests/sandbox/test_isolation.py` (no change)
-- **Action:** Record the A-101 probe transcript in README (verbatim commands + observed output from this box: `unshare --user --map-root-user --mount --pid --fork --net id -u` → `0`; `ip link` → loopback only; write containment). Document the v0.3 resource-limit mechanism choice: cgroup-v2 delegation via per-sandbox scope files is **not available** on this box without sudo → enforcement = subprocess-level (`ulimit`-equivalent via `preexec_fn`: RLIMIT_AS for memory, RLIMIT_CPU for CPU-seconds, RLIMIT_NPROC for pids) + hard wall-clock timeout kill in the manager. This is the locked v0.3 mechanism (D-024 + no-sudo constraint). Run ruff over the new tree; fix all findings.
-- **Verify:** `pnpm ai:lint` exits 0; README shows the probe transcript and the rlimit mechanism note
-
-### Wave 2: Lifecycle manager (depends on Wave 1)
-
-#### Task 1-2-01: Sandbox manager + concurrency guard + snapshots
-- **Persona:** sandbox-engineer — **REQ:** REQ-3-001, REQ-3-002
-- **Files:** `apps/ai-service/ai_service/sandbox/manager.py`, `apps/ai-service/tests/sandbox/test_manager.py`
-- **Action:** `SandboxManager`: `create(learner_id) -> SandboxHandle` (guard: active count ≥ `AI_SANDBOX_MAX_CONCURRENT` → raise `PoolFullError` → API maps to **503**, D-032; no queue); `list() -> list[SandboxHandle]`; `get(id)`; `snapshot(id) -> Path` (delegates to workdir); `destroy(id)` (kill process tree, keep or purge workdir per flag); `reap_expired()` background hook for `AI_SANDBOX_TIMEOUT_S` which also performs a **workdir-size sweep**: any sandbox whose `workdir` exceeds `AI_SANDBOX_MAX_WORKDIR_MB` (new config, default 512) is snapshotted-then-destroyed and the event logged as an integrity signal (G-2 — soft disk cap, best-effort, not kernel-enforced); the sweep runs on the same timer as the timeout reaper. Enforce rlimits per spawner (Task 1-1-03: RLIMIT_AS + RLIMIT_CPU + RLIMIT_FSIZE=50MB as a cheap single-file disk guard (a-2); RLIMIT_NPROC noted as shared-per-host-uid, not relied on (G-1)) at exec time. Handle registry persisted **in-memory** (v0.3, single process; not a store — see D-019 precedent) with a clear note that handles are process-local. Startup reaper (a-1): on lifespan boot, scan `AI_SANDBOX_DIR` for workdirs whose recorded pid is dead and reap them, logging a warning. Narrow typed interface only — manager never imports api/ (boundary rule).
-- **Verify:** `pnpm ai:test` — test_manager covers create/list/destroy/snapshot, 6th create raises PoolFullError (503 path), destroy kills the namespace process (pid gone), snapshot dir exists with workspace contents, timeout reaper removes a stale handle
-
-#### Task 1-2-02: Resource-limit enforcement test
-- **Persona:** sandbox-engineer — **REQ:** REQ-3-002
-- **Files:** `apps/ai-service/tests/sandbox/test_resource_limits.py`
-- **Action:** Concrete enforcement probes (guarded like isolation tests): (a) spawn a process that allocates > `RLIMIT_AS` → assert it dies with MemoryError/killed within a bound; (b) spawn a CPU spinner past `RLIMIT_CPU` → assert SIGXCPU/kill; (c) single huge file > `RLIMIT_FSIZE` → assert write failure (a-2 partial disk guard); (d) wall-clock: spawn `sleep 9999` with a small manager timeout → reaper destroys it; (e) **disk sweep (G-2)**: write > `AI_SANDBOX_MAX_WORKDIR_MB` across many files → assert the manager sweep destroys the sandbox and logs the integrity signal. Assert limits are observable (handle reports its limit set). NOTE (G-1): per-sandbox `RLIMIT_NPROC` is shared at the host uid — the fork-bomb probe is documented as shared-budget behavior, NOT asserted as per-sandbox isolation.
-- **Verify:** `pnpm ai:test` — test_resource_limits green; limits proven enforced and observable
-
-### Wave 3: API exposure (depends on Wave 2)
-
-#### Task 1-3-01: Sandboxes API module
-- **Persona:** backend-engineer — **REQ:** REQ-3-001, REQ-3-002
-- **Files:** `apps/ai-service/ai_service/api/sandboxes.py`, `apps/ai-service/ai_service/main.py` (update: include router + lifespan manager), `apps/ai-service/ai_service/api/deps.py` (update), `apps/ai-service/tests/api/test_sandboxes.py`
-- **Action:** DI exposes a singleton `SandboxManager`. Endpoints: `POST /v1/sandboxes {learner_id}` → 201 handle (503 when pool full); `GET /v1/sandboxes` → list; `GET /v1/sandboxes/{id}` → handle; `POST /v1/sandboxes/{id}/snapshot` → snapshot path; `DELETE /v1/sandboxes/{id}` → 204. All behind localhost CORS (A-008). Lifespan creates/destroys the manager; on shutdown destroys any live sandboxes (no orphans). **Abuse control (G-5, NOT KYC):** even in no-auth v0.3 the sandbox API enforces per-`learner_id` rate limiting (`AI_SANDBOX_MAX_PER_LEARNER`, default 1 active → 429) and a global create-rate cap (`AI_SANDBOX_CREATES_PER_MIN`, default 10 → 429); `learner_id` is validated against a server-side allowlist from config (`AI_LEARNER_ALLOWLIST`, default the single mock pilot id → unknown ids rejected 403). This ships in the no-auth milestone so a rogue local process can't exhaust shared NPROC/disk.
-- **Verify:** `pnpm ai:test` — test_sandboxes green (create→list→snapshot→delete roundtrip via TestClient; 6th create → 503; delete of unknown id → 404; abuse control (G-5): non-allowlisted learner_id → 403; >1 active sandbox for one learner → 429; burst of >10 creates/min → 429); manual probe: `curl -X POST localhost:8420/v1/sandboxes -d '{"learner_id":"l1"}'` returns a handle id
-
-### Must-Haves (Phase 1)
-- [ ] Isolation probe test green on this box: in-namespace uid=0, network isolated (0 usable interfaces), host writes confined to the per-sandbox bind dir (A-101 re-verified as an automated test, not just research notes)
-- [ ] Resource limits enforced + observable: memory (RLIMIT_AS) + CPU (RLIMIT_CPU) rlimits kill violating processes; wall-clock reaper destroys stale sandboxes; disk usage capped by a periodic workdir-size sweep in the manager (soft cap, configurable `AI_SANDBOX_MAX_WORKDIR_MB`, default 512MB — NOT kernel-enforced); per-sandbox NPROC is shared across sandboxes at the host uid — documented, not relied on for isolation (G-1, G-2 — test_resource_limits green)
-- [ ] No cross-tenant access: sandbox A cannot read sandbox B's workdir (isolation test asserts containment)
-- [ ] Lifecycle API works end-to-end: create/list/snapshot/destroy via TestClient; pool full → **503** (D-032, no queue)
-- [ ] Snapshot produces a restorable directory copy under the sandbox's own snapshots/ dir
-- [ ] `pnpm ai:test` and `pnpm ai:lint` green; new deps (`sqlmodel`, `sqlalchemy`, `websockets`, `aiofiles`) installed via idempotent bootstrap
-- [ ] Boundary rules hold: `sandbox/` imports nothing from `api/` or `agents/`; only `api/sandboxes.py` composes the manager via DI
-- [ ] No docker/podman/sudo anywhere in the spawner path (D-024); `SandboxBackend` protocol is the only coupling to the spawner (containerd swap possible later)

-**Requirements:** REQ-3-003
-**Goal:** First real persistence (D-027: SQLite via SQLModel) with a `TraceStore` protocol; `TelemetryEvent` model with per-(learner,task) monotonic `seq`; WebSocket ingest endpoint (D-026) with gap detection; stdlib-only in-sandbox capture agent streams real sandbox activity into ai-service; trace retrievable by learner+task

-- **Action:** Pydantic/SQLModel `TelemetryEvent`: `learner_id`, `task_id`, `seq` (int, monotonic per (learner,task)), `kind` (`command` | `file_diff` | `run_result` | `test_result` | `activity` | `stdin` | `stdout`), `payload` (JSON), `ts` (datetime, monotonic-envelope), `sandbox_id`. `TraceSpan` derived view (ordered events for one (learner,task)). Validation: seq ≥ 0, kind enum, non-empty ids.
-- **Verify:** `pnpm ai:test` — test_models green (validation rules enforced, JSON payload roundtrip)

-#### Task 2-1-02: TraceStore protocol + SQLite implementation
-- **Persona:** backend-engineer — **REQ:** REQ-3-003
-- **Files:** `apps/ai-service/ai_service/telemetry/store.py`, `apps/ai-service/tests/telemetry/test_store.py`, `apps/ai-service/ai_service/data/.gitkeep`
-- **Action:** `TraceStore` protocol (D-027, Postgres-migration-ready): `append(event) -> None` (idempotent on (learner,task,seq) — at-least-once dedup), `get_trace(learner_id, task_id) -> list[TelemetryEvent]` (ordered by seq), `gaps(learner_id, task_id) -> list[int]` (missing seqs), `latest_seq(learner_id, task_id) -> int`, `list_tasks(learner_id) -> list[str]`, `close()`. `SQLiteTraceStore(SQLModel)`: single `telemetry_event` table, composite PK ((learner_id, task_id, seq)), indexes on (learner_id, task_id). Engine creation from `AI_DB_PATH`; `SQLModel.metadata.create_all` at app lifespan. Enable `PRAGMA journal_mode=WAL` + `synchronous=NORMAL` at engine creation (a-3) so concurrent ingest (writer) and trace reads (grader) don't hit `database is locked` under concurrent sandboxes.
-- **Verify:** `pnpm ai:test` — test_store green (append/ordered-get/dedup-on-retry/gap detection/latest_seq; tmp-path SQLite per test)
-
-#### Task 2-1-03: TS types for telemetry/traces
-- **Persona:** data-engineer — **REQ:** REQ-3-003
-- **Files:** `packages/types/telemetry.ts` (new), `packages/types/index.ts` (update)
-- **Action:** TS `TelemetryEvent`, `TraceSpan`, `TelemetryKind` mirroring the Python model field-for-field (cross-referencing header, same string enums). Consumed by Phase 6 web surfaces; no runtime code.
-- **Verify:** `pnpm typecheck` passes; TS type keys match Python model keys exactly
-
-### Wave 2: Capture agent + ingest (depends on Wave 1)
-
-#### Task 2-2-01: In-sandbox capture agent (stdlib-only)
-- **Persona:** sandbox-engineer — **REQ:** REQ-3-003
-- **Files:** `apps/ai-service/scripts/sandbox-agent.py`, `apps/ai-service/tests/sandbox/test_sandbox_agent.py`
-- **Action:** Tiny standalone process (D-031, **stdlib only** — no deps shipped into the namespace): wraps a shell inside the sandbox; captures commands, file diffs (mtime/content polling of `workspace/` at 250ms), run/test results, activity; assigns per-(learner,task) `seq`; buffers to a local spool file on disconnect (at-least-once, D-026); reconnects with **exponential backoff** and flushes spool in order; small WebSocket client implemented over raw `socket` (RFC6455 client handshake + frames — stdlib only, no `websockets` in-namespace). Configured via env baked at spawn (`NC_LEARNER_ID`, `NC_TASK_ID`, `NC_INGEST_URL`).
-- **Verify:** `pnpm ai:test` — unit tests with a loopback fake WS server: ordered seq emission, spool-on-disconnect, reconnect flush preserves order (no loss, dupes deduped server-side), no third-party imports in the file (asserted by AST scan)
-
-#### Task 2-2-02: WebSocket ingest endpoint
-- **Persona:** backend-engineer — **REQ:** REQ-3-003
-- **Files:** `apps/ai-service/ai_service/telemetry/ingest.py`, `apps/ai-service/ai_service/api/sandboxes.py` (update: register WS route), `apps/ai-service/ai_service/main.py` (update), `apps/ai-service/tests/api/test_telemetry_ingest.py`
-- **Action:** `WS /v1/telemetry/ingest` (D-026): accepts connections carrying learner_id/task_id/sandbox_id; validates + appends events to `TraceStore` (idempotent — server-side dedup on (learner,task,seq)); emits **gap warnings** when seq skips (logged + surfaced in a per-connection status); ping/pong keepalive. **Backpressure / flood control (G-3 — replaces silent drop):** bounded inbound queue; on overflow OR when a per-connection cap `AI_TELEMETRY_MAX_EVENTS_PER_TASK` (default 50000) is exceeded → **reject with a 1008 policy-violation close and mark the (learner,task) trace `INCOMPLETE_FLOODED`** (an integrity signal consumed by Proctor). Silent drop-oldest is FORBIDDEN because it corrupts grading input and is indistinguishable from trace-gaming. `GET /v1/telemetry/traces/{learner_id}/{task_id}` returns the ordered trace; `GET /v1/telemetry/gaps/{learner_id}/{task_id}` returns missing seqs.
-- **Verify:** `pnpm ai:test` — test_telemetry_ingest green (TestClient websocket: connect → send 3 events → trace retrievable ordered; resend event 2 → deduped; skip seq 5 → gap reported; unknown sandbox tolerated in v0.3 no-auth mode)
-
-### Wave 3: Sandbox telemetry wiring (depends on Wave 2)
-
-#### Task 2-3-01: Spawn sandboxes with the capture agent
-- **Persona:** sandbox-engineer — **REQ:** REQ-3-003
-- **Files:** `apps/ai-service/ai_service/sandbox/manager.py` (update), `apps/ai-service/ai_service/sandbox/unshare_backend.py` (update), `apps/ai-service/tests/sandbox/test_telemetry_wiring.py`
-- **Action:** `create()` gains optional `task_id`; when set the spawner copies `scripts/sandbox-agent.py` into the sandbox workdir, injects `NC_*` env, and launches the agent as a child of the namespace process (agent lifecycle tied to sandbox lifecycle; destroy kills the agent). No capture when task_id absent (pure shell sandbox).
-- **Verify:** `pnpm ai:test` — end-to-end on this box: create sandbox with task_id → run 2 commands via exec → events arrive at the ingest endpoint and land in SQLite in order
-
-### Wave 4: Reliability probe (depends on Wave 3)
-
-#### Task 2-4-01: Dropped-connection durability probe
-- **Persona:** backend-engineer — **REQ:** REQ-3-003
-- **Files:** `apps/ai-service/tests/telemetry/test_durability.py`
-- **Action:** Integration probe: run a capture agent against ingest, kill the WS connection mid-stream (simulate network failure), keep generating events, reconnect, assert the SQLite trace contains **every** event exactly once in order (spool + dedup). Document at-least-once semantics + replay path in README.
-- **Verify:** `pnpm ai:test` — test_durability green; README documents semantics
-
-### Must-Haves (Phase 2)
-- [ ] Real telemetry from a live sandbox arrives at ai-service: shell commands, file diffs, run/test results appear as ordered events in SQLite (end-to-end, no mocks)
-- [ ] Per-(learner,task) monotonic `seq`; gap detection reports missing seqs; replay yields the complete ordered trace
-- [ ] At-least-once proven: transient disconnect + reconnect loses no events; duplicates deduped server-side (durability probe green)
-- [ ] Capture agent is stdlib-only (AST-verified) and its lifecycle is tied to the sandbox (destroy kills it)
-- [ ] Trace retrievable by learner+task via `GET /v1/telemetry/traces/...`; unknown trace → 404
-- [ ] `TraceStore` protocol respected: no api/ code touches SQLite directly; `telemetry/` never imports `agents/` (D-027)
-- [ ] Flood control (G-3): burst past `AI_TELEMETRY_MAX_EVENTS_PER_TASK` → connection closed 1008 + trace marked `INCOMPLETE_FLOODED`; no silent event drop on overflow
-- [ ] `pnpm ai:test` green; `packages/types` telemetry TS types compile (`pnpm typecheck`)

-## Phase 3: Process-Trace Grading Engine
-
-**Requirements:** REQ-3-004
-**Goal:** Deterministic feature computation over traces (D-028) → compact digest → LLM rubric scoring via existing D-020 JSON defense → validated structured scores stored in `GradeStore`; LLM never sees the raw trace; engine calibrated against v0.2 mock corpora so process quality separates paste-and-run from iterative debugging
-
-### Wave 1: Features + grades store (parallel — no shared files)
-
-#### Task 3-1-01: Deterministic trace digest (features)
-- **Persona:** ai-engineer — **REQ:** REQ-3-004
-- **Files:** `apps/ai-service/ai_service/grading/__init__.py`, `apps/ai-service/ai_service/grading/features.py`, `apps/ai-service/tests/grading/__init__.py`, `apps/ai-service/tests/grading/test_features.py`
-- **Action:** Pure compute module (D-028): `compute_digest(trace: list[TelemetryEvent]) -> TraceDigest`. Deterministic features: test pass/fail counts + final status; edit count; error/fix cycle count + mean fix latency; idle gaps (>Ns, count + total); command category histogram (build/test/file/nav/debug/other); session duration; first-test-pass offset. `TraceDigest` pydantic model — compact (bounded size, no raw commands), LLM-safe.
-- **Verify:** `pnpm ai:test` — test_features green over synthetic traces: paste-and-run trace (0 error/fix cycles, single test pass at end) vs iterative trace (many cycles) produce observably different digests
-
-#### Task 3-1-02: GradeStore protocol + SQLite implementation
-- **Persona:** backend-engineer — **REQ:** REQ-3-004
-- **Files:** `apps/ai-service/ai_service/grading/store.py`, `apps/ai-service/tests/grading/test_store.py`
-- **Action:** `GradeStore` protocol (D-027): `save(grade)`, `get(learner_id, task_id)`, `list_for_learner(learner_id)`, `close()`. SQLModel `GradeRecord`: learner_id, task_id, variant_seed (null until P4), digest (JSON), scores (JSON), verdict, model, created_at. PK (learner_id, task_id). Postgres-migration-ready.
-- **Verify:** `pnpm ai:test` — test_store green (save/get/list roundtrip, overwrite-on-regrade documented)
-
-### Wave 2: Grading engine + calibration (depends on Wave 1)
-
-#### Task 3-2-01: Rubric scoring engine
-- **Persona:** ai-engineer — **REQ:** REQ-3-004
-- **Files:** `apps/ai-service/ai_service/grading/engine.py`, `apps/ai-service/ai_service/prompts/grading.py` (new), `apps/ai-service/tests/grading/test_engine.py`
-- **Action:** `GradingEngine.grade(learner_id, task_id) -> GradeRecord`: **trace-completeness gate (G-4)** — first call `TraceStore.gaps()` + check the trace `INCOMPLETE_FLOODED` flag; if gaps are non-empty OR the trace is flagged incomplete → return `verdict=UNGRADABLE_TRACE_INCOMPLETE` (a first-class verdict, not an exception) surfacing the gap list; a credential is NEVER issued from a gapped/incomplete trace. Otherwise: load trace via `TraceStore` → `compute_digest` → render rubric prompt (`prompts/grading.py`: criteria + level anchors for process quality, correctness, debugging discipline, test usage; a-4: treat high edit/command churn with no test-progress as a process-quality negative) → LLM structured output through the **existing D-020 4-layer defense** (`agents/structured.py` reused — engine composes it, never duplicates it) → validate `RubricScore` model (per-criterion 0-4 + strengths + gaps + verdict) → persist via `GradeStore`. Grading depends on `llm/` + `telemetry/` + `prompts/` only (boundary). Mock provider scripts deterministic rubric JSON for tests, including the INCOMPLETE path.
-- **Verify:** `pnpm ai:test` — test_engine green (mock provider: digest-only prompt asserted — **raw trace string absent from prompt**; validated scores returned; malformed JSON exercises D-020 retry; unknown trace → error)
-
-#### Task 3-2-02: Calibration against v0.2 mock corpora
-- **Persona:** ai-engineer — **REQ:** REQ-3-004
-- **Files:** `apps/ai-service/ai_service/corpus/trace_fixtures.py` (new), `apps/ai-service/tests/grading/test_calibration.py`
-- **Action:** Synthetic trace fixtures aligned with v0.2 `corpus/telemetry.py` + `corpus/artifacts.py` scenario IDs (strong/lazy/struggling builder archetypes). Assert grading separates them: strong archetype scores ≥ lazy archetype on process-quality criterion (mock provider maps digest shape → scripted scores; test asserts the ordering contract + that fixture IDs align with existing corpus IDs, D-021).
-- **Verify:** `pnpm ai:test` — test_calibration enforces the ordering contract
-
-### Wave 3: Grading endpoint (depends on Wave 2)
-
-#### Task 3-3-01: Assessment grade endpoint (real traces)
-- **Persona:** backend-engineer — **REQ:** REQ-3-004
-- **Files:** `apps/ai-service/ai_service/api/assessment.py` (update), `apps/ai-service/tests/api/test_grading.py`
-- **Action:** `POST /v1/assessment/grade {learner_id, task_id}` → `GradingEngine` → validated `RubricScore` JSON; `GET /v1/assessment/grade/{learner_id}/{task_id}` → stored grade; unknown trace → 404. Composed via DI (api/ owns wiring; engine knows nothing of FastAPI).
-- **Verify:** `pnpm ai:test` — test_grading green (grade roundtrip via TestClient with mock provider; 404 on unknown; GET after POST returns same scores)
-
-### Must-Haves (Phase 3)
-- [ ] Engine emits structured rubric-aligned scores from a **real process trace** (not pre-baked input) — TestClient roundtrip green
-- [ ] Deterministic features computed in code (test pass/fail, edit count, error/fix cycles, idle gaps, command categories); LLM receives the **digest only** — test asserts the raw trace never reaches the prompt (D-028)
-- [ ] Scores distinguish process quality: iterative-debugging archetype out-scores paste-and-run on the process criterion (calibration contract test)
-- [ ] Grades persisted + retrievable by learner+task via GradeStore (SQLite, protocol-wrapped, D-027)
-- [ ] Boundary rules hold: `grading/` imports no `api/`/`agents/` internals except the shared D-020 structured defense; `pnpm ai:test` + `pnpm ai:lint` green
-- [ ] Incomplete-trace gate (G-4): gapped or `INCOMPLETE_FLOODED` trace → `verdict=UNGRADABLE_TRACE_INCOMPLETE` with the gap list; no credential issued from an incomplete trace (test green)

-## Phase 4: Variant Task Generation
-
-**Requirements:** REQ-3-005
-**Goal:** Template library with typed parameter slots (D-029) + seeded LLM instantiation + per-learner variant registry (SQLite) with difficulty-normalization anchors; two learners on the same competency get provably distinct, reproducible, auditable tasks
-
-### Wave 1: Templates + store (parallel — no shared files)
-
-#### Task 4-1-01: Task template library
-- **Persona:** ai-engineer — **REQ:** REQ-3-005
-- **Files:** `apps/ai-service/ai_service/variants/__init__.py`, `apps/ai-service/ai_service/variants/templates.py`, `apps/ai-service/tests/variants/__init__.py`, `apps/ai-service/tests/variants/test_templates.py`
-- **Action:** ≥3 initial task templates bound to existing competency IDs (D-021 alignment). `TaskTemplate`: id, competency_id, statement skeleton with `{slot}` placeholders, `ParameterSlot[]` (name, type: enum/int-range/string-set, allowed values), `rubric anchors` (difficulty normalization: expected feature envelope — e.g. expected edit-count band — used by grading context), starter-file scaffolds served to the sandbox. Seeded slot sampler is pure code (`random.Random(seed)`), fully reproducible.
-- **Verify:** `pnpm ai:test` — test_templates green (slot validation: bad value rejected; seeded sampling reproducible across runs; all templates bind to real competency IDs)
-
-#### Task 4-1-02: VariantStore protocol + SQLite implementation
-- **Persona:** backend-engineer — **REQ:** REQ-3-005
-- **Files:** `apps/ai-service/ai_service/variants/store.py`, `apps/ai-service/tests/variants/test_store.py`
-- **Action:** `VariantStore` protocol (D-027): `save(variant)`, `get(learner_id, template_id_or_task_id)`, `list_for_learner(learner_id)`, `list_by_template(template_id)`, `close()`. SQLModel `VariantRecord`: learner_id, task_id (the grading/telemetry task key), template_id, seed, params (JSON), statement (rendered), created_at. Unique (learner_id, template_id).
-- **Verify:** `pnpm ai:test` — test_store green (roundtrip, unique constraint, audit listing)
-
-### Wave 2: Generator (depends on Wave 1)
-
-#### Task 4-2-01: Seeded LLM variant generator
-- **Persona:** ai-engineer — **REQ:** REQ-3-005
-- **Files:** `apps/ai-service/ai_service/variants/generator.py`, `apps/ai-service/ai_service/prompts/variant.py` (new), `apps/ai-service/tests/variants/test_generator.py`
-- **Action:** `VariantGenerator.generate(learner_id, template_id) -> VariantRecord`: derive seed (`sha256(template_id|learner_id|milestone)` — reproducible, D-029); sample typed slots in code; render a fill prompt (statement skeleton + concrete slot values) → LLM via D-020 structured defense → unique task statement + starter files → validate → persist (seed + params + statement) via `VariantStore`. Cache: existing (learner,template) returns the stored variant (no duplicate work). Mock provider scripts deterministic statements per seed for tests.
-- **Verify:** `pnpm ai:test` — test_generator green: two different learner_ids → distinct statements for the same template; same learner twice → identical stored variant (reproducible); params JSON contains only schema-valid slot values; **fairness envelope (a-5):** two variants of one template compute digests within the template's expected feature envelope (comparable slot complexity/difficulty features) — "same bar" is testable, not asserted
-
-### Wave 3: Variant endpoint + TS types (depends on Wave 2)
-
-#### Task 4-3-01: Variant task endpoint
-- **Persona:** backend-engineer — **REQ:** REQ-3-005
-- **Files:** `apps/ai-service/ai_service/api/variants.py` (new), `apps/ai-service/ai_service/main.py` (update), `apps/ai-service/tests/api/test_variants.py`
-- **Action:** `POST /v1/variants {learner_id, template_id or competency_id}` → generated (or cached) variant: statement, starter files, task_id, seed; `GET /v1/variants/{task_id}` → stored variant; `GET /v1/variants?learner_id=` → learner's variants. DI wiring in api/ only.
-- **Verify:** `pnpm ai:test` — test_variants green (generate→get roundtrip; cache hit on regenerate; distinct learners → distinct statements asserted at the API layer)
-
-#### Task 4-3-02: TS types for variants (+ grades)
-- **Persona:** data-engineer — **REQ:** REQ-3-005
-- **Files:** `packages/types/variants.ts` (new), `packages/types/grading.ts` (new), `packages/types/index.ts` (update)
-- **Action:** TS `TaskVariant`, `VariantParams`, `RubricScore`, `GradeRecord` matching Python models (cross-referencing headers; same field names). Consumed by Phase 6 surfaces.
-- **Verify:** `pnpm typecheck` passes
-
-### Must-Haves (Phase 4)
-- [ ] Two learners requesting the same competency receive **provably distinct** task variants (API-level test)
-- [ ] Seed derivation reproducible: same (template, learner) → same variant, served from cache without a second LLM call (D-029)
-- [ ] Variant seed + typed params persisted + auditable (VariantStore listing; proctoring cross-check path exists)
-- [ ] Difficulty normalization anchors present per template and shipped to the grader prompt context
-- [ ] Starter-file scaffolds defined per template (P6 wires them into the sandbox workdir)
-- [ ] `pnpm ai:test` + `pnpm typecheck` green; `variants/` imports no api/ (boundary)

-## Phase 5: Oral / Voice Defense
-
-**Requirements:** REQ-3-006
-**Goal:** `VoiceProvider` protocol with mock + browser fallback (D-030) + seventh `Examiner` agent streaming over existing SSE + `DefenseStore` persisting transcript + integrity signals. **Real server STT/TTS (`OpenAIAudioProvider`) is DEFERRED to v0.4 (with KYC, when there's a real key + real users)** — voice is mock-first (D-030) and the `/audio/*` real path could never be exercised in CI, so v0.3 proves the full defense *dialogue* + integrity-signal pipeline over mock + browser-native fallback only; the protocol seam keeps the real provider a drop-in later.
-
-### Wave 1: Voice provider layer (parallel — no shared files)
-
-#### Task 5-1-01: VoiceProvider protocol + mock provider + browser fallback
-- **Persona:** voice-engineer — **REQ:** REQ-3-006

-- **Action:** `VoiceProvider` protocol mirroring `LLMProvider` (D-030): `transcribe(audio: bytes, fmt) -> TranscriptSegment` + `synthesize(text, voice) -> AsyncIterator[bytes]`. `MockVoiceProvider`: deterministic canned transcript (scripted per test), canned 1kHz-tone WAV bytes, scripted failure modes. `browser.py`: fallback **descriptor** (`sr_available: true`, endpoint hints) the web client uses to select browser-native `SpeechRecognition`/`speechSynthesis` when no server provider. `factory.py`: `AI_VOICE_PROVIDER=browser | mock` (default mock when no key). **`OpenAIAudioProvider` (real server STT/TTS) intentionally NOT built in v0.3 — deferred to v0.4**; the protocol is its future seam. `voice/` never imports `agents/` or `api/`.
-- **Verify:** `pnpm ai:test` — test_mock + test_factory green (deterministic transcribe/synthesize; failure modes; factory selects mock with empty key, browser when provider=browser; zero network calls)
-
-#### Task 5-1-03: DefenseStore protocol + SQLite implementation
-- **Persona:** backend-engineer — **REQ:** REQ-3-006
-- **Files:** `apps/ai-service/ai_service/voice/defense_store.py`, `apps/ai-service/tests/voice/test_defense_store.py`
-- **Action:** `DefenseStore` protocol (D-027): `start(defense)`, `append_turn(defense_id, turn)`, `finalize(defense_id, integrity_signals)`, `get(defense_id)`, `list_for_learner(learner_id)`, `close()`. SQLModel `DefenseRecord` (id, learner_id, task_id, status, created/finished_at) + `DefenseTurn` (defense_id FK, turn seq, role examiner|learner, text, ts, latency_ms) + integrity signals JSON on the record (long pauses, off-scope cadence markers — A-109).
-- **Verify:** `pnpm ai:test` — test_defense_store green (start→append turns→finalize→get roundtrip; ordered turns by seq)
-
-### Wave 2: Examiner agent (depends on Wave 1)
-
-#### Task 5-2-01: Examiner agent (seventh agent)
-- **Persona:** ai-engineer — **REQ:** REQ-3-006
-- **Files:** `apps/ai-service/ai_service/agents/examiner.py`, `apps/ai-service/ai_service/prompts/examiner.py` (new), `apps/ai-service/ai_service/agents/registry.py` (update: central registration, G-4 pattern), `apps/ai-service/tests/agents/test_examiner.py`
-- **Action:** `ExaminerAgent(BaseAgent)` (D-030/A-109): builds questions from learner transcript + trace digest + (P4) variant statement; probes understanding + challenges process choices ("why did you choose X at step N?"); streams questions over the existing SSE pipeline; `structured` verdict mode returns verdict + per-answer integrity signal list (long pause flags, off-scope answers) computed from turn metadata; calls voice **only through the `VoiceProvider` protocol** (PERSONAS conflict rule — never concrete providers). Session-scoped history reused from v0.2.
-- **Verify:** `pnpm ai:test` — test_examiner green (question stream references trace-digest facts; verdict structured output validates via D-020 defense; registry resolves all seven agents; mock-VoiceProvider wiring through protocol only — asserted by import scan in test)
-
-### Wave 3: Defense endpoints (depends on Wave 2)
-
-#### Task 5-3-01: Defense session + audio endpoints
-- **Persona:** backend-engineer — **REQ:** REQ-3-006
-- **Files:** `apps/ai-service/ai_service/api/defense.py` (new), `apps/ai-service/ai_service/main.py` (update), `apps/ai-service/tests/api/test_defense.py`
-- **Action:** `POST /v1/defense/start {learner_id, task_id}` → creates DefenseRecord + streams the first examiner question (SSE, agent=examiner); `POST /v1/defense/{id}/answer` (multipart audio from browser MediaRecorder, or `{text}` for typed fallback) → STT via VoiceProvider → append learner turn → stream examiner follow-up (SSE) → TTS audio chunks over `GET /v1/defense/{id}/audio/{turn_id}`; `POST /v1/defense/{id}/finish` → verdict + integrity signals persisted; `GET /v1/defense/{id}` → full transcript + signals. Browser-fallback mode: when provider=browser, start returns the fallback descriptor instead of server audio.
-- **Verify:** `pnpm ai:test` — test_defense green (full loop with mock voice + mock LLM: start → answer(text) → answer(audio bytes) → finish → transcript retrievable with per-turn latency; unknown id → 404; `GET` signals present after finish)
-
-### Wave 4: Examiner latency instrumentation (depends on Wave 3)
-
-#### Task 5-4-01: Per-turn latency instrumentation (mock-based)
-- **Persona:** voice-engineer — **REQ:** REQ-3-006
-- **Files:** `apps/ai-service/tests/voice/test_latency.py`, `apps/ai-service/README.md` (update: conversational-budget doc + v0.4 voice note)
-- **Action:** Instrument per-turn latency (STT ms + LLM TTFT ms + TTS ms) recorded on each DefenseTurn; deterministic test over mock providers asserts instrumentation presence + `latency_ms` populated + budget constant defined (mock runs are near-instant — wall-clock asserted in v0.4 against a real endpoint). README documents the conversational-latency target as a v0.4 acceptance criterion (real STT/TTS deferred per CUT-1/G-7).
-- **Verify:** `pnpm ai:test` — test_latency green (latency_ms fields populated on every turn; budget constant defined); README documents the deferred real-voice acceptance probe
-
-### Must-Haves (Phase 5)
-- [ ] Spoken defense runs end-to-end over HTTP with mock providers: start → answer (audio + typed fallback) → examiner follow-up streams → verdict + transcript persisted (automated)
-- [ ] Examiner is the seventh registered agent; streams over the existing SSE envelope (meta agent=examiner)
-- [ ] Instrumented per-turn latency fields populated on every DefenseTurn (STT ms + LLM TTFT ms + TTS ms); conversational budget named (A-109)
-- [ ] `VoiceProvider` protocol respected: examiner + api touch voice only via the protocol; mock-first — **no task requires a real voice key to pass**
-- [ ] Browser-native SR/TTS fallback descriptor returned when no server voice provider configured (mock/browser are first-class, D-030)
-- [ ] Real server STT/TTS (`OpenAIAudioProvider`) explicitly deferred to v0.4 (with real keys/users); the defense pipeline is fully proven over mock+browser — documented in README + release note
-- [ ] Optional future voice config noted for v0.4 (`AI_VOICE_BASE_URL` / `AI_VOICE_API_KEY`) in `.env.example` + README; keys only in gitignored `.ciagent/.env.secrets`; tests never call a voice API
-- [ ] Boundary rules hold: `voice/` imports no `agents/`/`api/`; `pnpm ai:test` + `pnpm ai:lint` green

-
-## Phase 6: Agent Re-grounding + Learner Surface Integration
-
-**Requirements:** REQ-3-007, REQ-3-008
-**Goal:** Lab/Assessor/Proctor consume real engine inputs (live telemetry, grading output, defense signals) with **no mock fallback in the learner path**; the v0.1 sandbox + assessment mockups become real — in-browser build/run (Run/Test buttons + read-only exec output, CUT-2 — no interactive shell), live telemetry panel, browser/typed voice defense, live grading; `pnpm build` + `pnpm typecheck` + full `pnpm ai:test` green
-**Note:** E2E verification runs against the real engines over HTTP with `AI_PROVIDER=mock` + `AI_VOICE_PROVIDER=mock` permitted (G-2 precedent) — the requirement is real engine plumbing (sandbox/telemetry/grading/defense over real endpoints, no corpus mocks in the learner path); a cloud outage must not block P6.

-#### Task 6-1-01: Lab agent on live telemetry
-- **Persona:** ai-engineer — **REQ:** REQ-3-007
-- **Files:** `apps/ai-service/ai_service/agents/lab.py` (update), `apps/ai-service/ai_service/prompts/lab.py` (update: render real trace digest), `apps/ai-service/tests/agents/test_lab_live.py` (new)
-- **Action:** Lab consumes a **live trace digest** (grading/features `compute_digest` over `TraceStore` events) instead of `corpus/telemetry.py`. build_messages renders digest facts (recent commands, failing tests, idle). Mock-provider scripts assert digest-derived content. v0.2 corpus path removed from the agent (dormant corpus retained until Task 6-1-04 check).
-- **Verify:** `pnpm ai:test` — test_lab_live green: feedback references events actually present in a seeded SQLite trace (not corpus fixtures); no `corpus.telemetry` import in `agents/lab.py` (AST-asserted)
-
-#### Task 6-1-02: Assessor agent on grading output
-- **Persona:** ai-engineer — **REQ:** REQ-3-007
-- **Files:** `apps/ai-service/ai_service/agents/assessor.py` (update), `apps/ai-service/ai_service/prompts/assessor.py` (update), `apps/ai-service/tests/agents/test_assessor_live.py` (new)
-- **Action:** Assessor consumes `GradeStore` output (validated `RubricScore` + digest) for learner+task instead of pre-baked artifacts/transcripts; renders strengths/gaps/verdict with rubric-anchored coaching framing. Structured output unchanged (D-020).
-- **Verify:** `pnpm ai:test` — test_assessor_live green: given a real stored grade, Assessor output reflects its scores; corpus artifact path gone from the agent (AST-asserted)
-
-#### Task 6-1-03: Proctor agent on telemetry + defense signals
-- **Persona:** ai-engineer — **REQ:** REQ-3-007
-- **Files:** `apps/ai-service/ai_service/agents/proctor.py` (update), `apps/ai-service/ai_service/prompts/proctor.py` (update), `apps/ai-service/tests/agents/test_proctor_live.py` (new)
-- **Action:** Proctor consumes real integrity inputs: idle gaps + command cadence from the trace digest + defense integrity signals from `DefenseStore` → classified signals + coaching interventions (supportive tone retained). Cross-checks variant seed params (P4) for off-template work.
-- **Verify:** `pnpm ai:test` — test_proctor_live green: signals derived from seeded real trace + defense records; corpus proctor scenarios no longer imported (AST-asserted)
-
-#### Task 6-1-04: Corpus dormancy + mockup removal verification
-- **Persona:** lead-developer — **REQ:** REQ-3-007
-- **Files:** `apps/ai-service/ai_service/corpus/telemetry.py`, `apps/ai-service/ai_service/corpus/artifacts.py`, `apps/ai-service/ai_service/corpus/` (README note), `apps/ai-service/tests/test_corpus_dormancy.py` (new)
-- **Action:** Verify no production code path imports `corpus/telemetry.py` or `corpus/artifacts.py` anymore (test scans imports across `agents/`, `api/`, engines). Retain files as Phase-3 calibration history with a header note marking them **dormant — v0.2 mocks, not used at runtime**; learner-context corpus stays (agents still need learner context). Disposes v0.2's G-5-class dead-code risk deliberately.
-- **Verify:** `pnpm ai:test` — test_corpus_dormancy green (zero runtime importers); suite otherwise unchanged
-
-### Wave 2: Client plumbing + design primitives (parallel — no shared files)
-
-#### Task 6-2-01: Sandbox build-panel engine client (run/test-only — no raw shell relay)
-- **Persona:** frontend-engineer — **REQ:** REQ-3-008
-- **Files:** `apps/web/hooks/use-sandbox-session.ts` (new), `apps/web/lib/engine-client.ts` (new), `apps/web/.env.example` (update)
-- **Action:** `engine-client.ts`: typed fetch client for `/v1/sandboxes` (create/destroy — learner_id from the v0.3 mock session constant, allowlisted server-side per G-5), `/v1/sandboxes/{id}/files` (workspace CRUD), `/v1/sandboxes/{id}/exec` (run/test), `/v1/variants`, `/v1/assessment/grade`, `/v1/telemetry/traces`, `/v1/defense/*`; base `NEXT_PUBLIC_AI_SERVICE_URL`. `use-sandbox-session.ts`: create sandbox+variant on task open → destroy on unmount (idempotent cleanup, AbortController pattern); 503 pool-full → user-facing "environment busy, retry" (D-032); 403/429 abuse-control surfaced honestly (G-5). **CUT-2 (G-8): NO raw interactive WS terminal relay (keystroke-level stdin/stdout) in v0.3** — the credential pipeline needs *process events* (from Run/Test + file edits), not a live shell; the interactive xterm relay is the most fragile real-time piece and is deferred to v0.4. The build panel is a **Run/Test output viewer** (exec results + telemetry pulse render), not an interactive shell. `@xterm/xterm` is therefore NOT a dependency in v0.3.
-- **Verify:** `pnpm install && pnpm typecheck` pass; hook unmount destroys the sandbox (manual probe: `curl localhost:8420/v1/sandboxes` shows count drop after navigation); RUN/TEST buttons produce streamed output + telemetry events in the trace
-
-#### Task 6-2-02: New design primitives
-- **Persona:** design-system-engineer — **REQ:** REQ-3-008
-- **Files:** `packages/ui/src/primitives/terminal-frame.tsx` (new), `packages/ui/src/primitives/mic-control.tsx` (new), `packages/ui/src/primitives/grade-badge.tsx` (new), `packages/ui/src/primitives/telemetry-status.tsx` (new), `packages/ui/src/primitives/transcript-viewer.tsx` (new), `packages/ui/src/primitives/index.ts` (update), `packages/ui/src/index.ts` (update)
-- **Action:** Token-driven primitives: TerminalFrame (CUT-2: a read-only exec-output viewer chrome — streams Run/Test results, NOT an interactive shell), MicControl (record/stop with consent state + no-mic fallback state, MediaRecorder permission UX), GradeBadge (verdict rendering), TelemetryStatus (live event pulse / disconnected indicator), TranscriptViewer (examiner/learner turn list). Dark mode + WCAG AA; stories for each.
-- **Verify:** primitives import from `@nextcraft/ui`; Storybook stories render dark + light; `pnpm build` (ui package) passes
-
-#### Task 6-2-03: Defense TS types
-- **Persona:** data-engineer — **REQ:** REQ-3-008
-- **Files:** `packages/types/defense.ts` (new), `packages/types/index.ts` (update)
-- **Action:** TS `DefenseSession`, `DefenseTurn`, `IntegritySignal`, `Verdict` mirroring P5 Python models (cross-referencing header).
-- **Verify:** `pnpm typecheck` passes
-
-### Wave 3: Real build surface (depends on Wave 2)
-
-#### Task 6-3-01: Sandbox mockup → real in-browser IDE
-- **Persona:** frontend-engineer — **REQ:** REQ-3-008
-- **Files:** `apps/web/app/(learner)/build/[competencyId]/page.tsx` (rewrite), `apps/web/components/learner/sandbox-terminal.tsx` (new), `apps/web/components/learner/file-tree.tsx` (new), `apps/web/components/learner/run-controls.tsx` (new), `apps/web/components/learner/lab-feedback-panel.tsx` (update: live trace)
-- **Action:** Replace the mockup with the real build environment (A-103, CUT-2): file tree (HTTP CRUD into the sandbox workdir via `/v1/sandboxes/{id}/files` routes added to api/sandboxes — read/write/list workspace files), syntax-highlight editor (existing), **Run**/**Test** buttons (exec in sandbox; results stream to a read-only TerminalFrame output panel — no interactive shell), starter files from the P4 variant scaffold. Lab panel posts `learner_id+task_id` → streams Lab feedback over the **live** trace (no scenario IDs). Telemetry sidebar shows live TelemetryStatus. Pool-full 503 → busy state with retry; 403/429 surfaced.
-- **Verify:** with ai-service up: open `/build/comp-01` → variant statement + starter files load → edit a file → **Run** executes the command in-sandbox and output renders in the panel → **Test** runs the test suite in-sandbox → Lab panel streams digest-derived feedback → telemetry status shows live events. Manual probe documented; `pnpm typecheck` green
-
-### Wave 4: Live defense + grading surfaces (depends on Waves 2-3)
-
-#### Task 6-4-01: Assessment mockup → live defense + live grading
-- **Persona:** frontend-engineer — **REQ:** REQ-3-008
-- **Files:** `apps/web/app/(learner)/defend/[competencyId]/page.tsx` (rewrite), `apps/web/components/learner/defense-session.tsx` (new), `apps/web/components/learner/assessor-results-panel.tsx` (update), `apps/web/components/learner/proctor-banner.tsx` (update), `apps/web/components/learner/oral-defense-interface.tsx` (rewrite or remove)
-- **Action:** Real assessment flow: **Start Defense** → POST `/v1/defense/start` → examiner question streams → learner answers via MicControl (MediaRecorder webm/opus → multipart POST) with typed fallback when mic denied or `provider=browser` (native `SpeechRecognition`/`speechSynthesis` path per fallback descriptor) → follow-ups stream → **Finish** → verdict + integrity signals panel (TranscriptViewer, GradeBadge) + **Grade My Work** → POST `/v1/assessment/grade` → structured rubric bars render. Proctor banner reads signals for task_id. Loading + error states throughout; no mock defense data remains in the learner path.
-- **Verify:** with ai-service up: full defense loop runs in-browser (typed fallback acceptable in CI-less manual probe; mic path exercised manually with permission granted); grade panel renders real rubric scores; `pnpm typecheck` green
-
-### Wave 5: End-to-end verification (depends on Waves 3-4)
-
-#### Task 6-5-01: Full learner-path E2E probe + green builds
-- **Persona:** backend-engineer — **REQ:** REQ-3-007, REQ-3-008
-- **Files:** `apps/ai-service/tests/api/test_e2e_credential_flow.py` (new), `apps/ai-service/README.md` (update: E2E probe doc)
-- **Action:** Endpoint-level E2E (mock LLM/voice providers, real engines): create variant → create sandbox with task_id → ingest trace events via real sandbox exec → POST grade → start defense (typed answers) → finish → assert: trace persisted, grade stored + digest-linked, defense transcript + signals stored, Proctor/Assessor endpoints serve them. No corpus fixture anywhere in the flow (AST-asserted). Run `pnpm build` + `pnpm typecheck` + full `pnpm ai:test` at repo root; fix all failures before phase ship.
-- **Verify:** `pnpm ai:test` green incl. test_e2e_credential_flow; `pnpm build` + `pnpm typecheck` green; README E2E probe section documents the manual browser pass
-
-### Must-Haves (Phase 6)
-- [ ] Lab/Assessor/Proctor operate on real inputs with **no mock fallback in the learner path** (AST-verified: no corpus telemetry/artifact/proctor imports in production paths)
-- [ ] Learner builds in-browser for real (CUT-2): Run/Test buttons execute in a namespace sandbox and stream output to a read-only panel; file tree CRUD works; starter files come from the learner's variant scaffold
-- [ ] Live telemetry: build activity streams to ai-service and the sidebar shows live status (TelemetryStatus); trace persisted in SQLite
-- [ ] Live defense: start → answer (mic or typed fallback) → examiner follow-ups → finish → transcript + integrity signals + verdict rendered; browser-native path works with no server voice key
-- [ ] Live grading: grade request returns structured rubric scores computed from the real trace digest; grade panel renders them
-- [ ] 503 pool-full surfaced honestly in UI; navigating away destroys the sandbox (no leaked sandboxes — `GET /v1/sandboxes` manual probe)
-- [ ] Examiner remains protocol-clean (voice only via `VoiceProvider`); module boundary rules hold across all new code
-- [ ] `pnpm build` and `pnpm typecheck` pass; full `pnpm ai:test` green; no cloud/voice calls in any automated test
-- [ ] Release-note input (for P7): v0.3 ships real engines; **identity/age-gating (KYC) remains deferred — age-gating is still a visual mockup** (A-110); sandbox scope is coding-IDE only (design tool/simulation deferred to v0.4, D-025)
-
----
-
-## Phase 7: Final Review + Ship (no planned tasks)
-
-Orchestrated by the SHIP stage, not this plan: multi-persona code review (correctness, testing, module boundaries, secrets hygiene — keys absent from code/logs/commits/errors, localhost-only CORS, no PII in prompts), project health audit (reconstruction, .ciagent/ discipline, branch/commit hygiene), then merge milestone → main, tag the final v0.2.x patch, create the Gitea release, mark all 8 v0.3 requirements complete.
-
-**Release-note honesty:** the release note must state (a) Lab/Assessor/Proctor now run on real engine inputs (v0.2 mock-input caveat retired), (b) sandbox scope = coding IDE only — design tool + simulation environments deferred to v0.4 (D-025), (c) identity/age-gating (KYC) deferred per founder directive — age-gating remains the v0.1 visual flow mockup; abuse control (per-learner sandbox caps + server-side learner allowlist, G-5) ships in place of auth (A-110), (d) voice runs mock-first with browser-native fallback — real server STT/TTS deferred to v0.4 (CUT-1), (e) sandbox resource limits are partially enforced (memory/CPU/wall-clock kernel-enforced via rlimits; per-sandbox pids + hard disk quota are NOT — mitigated by a workdir-size sweep and per-learner caps; full enforcement requires cgroup delegation, deferred to the post-MVP containerd backend, D-024/G-1/G-2).
-
-**Secrets-hygiene checklist (P7):** `.ciagent/.env.secrets` gitignored and never committed; `AI_VOICE_API_KEY` / `AI_TUTOR_API_KEY` referenced only via env; SQLite DBs + sandbox dirs gitignored; no keys in logs, error messages, or test fixtures.
-
-**Disposal checks (G-5 class):** v0.2 dormant corpus files carry the dormant-header note (Task 6-1-04); any now-unused mock-data exports for the old sandbox/defense mockups (e.g. `aiTutorResponses`-class leftovers) must be removed or deprecated by review.

 ## User-Facing Surface
 
-The primary user-facing surface is the **learner build + defend flow** at `http://localhost:3000`, backed by the real engines in ai-service at `http://localhost:8420`:
-
-- `/dashboard` — AI tutor chat (Coach/Tutor, streaming) + Mentor panel (unchanged from v0.2)
-- `/learn/[competencyId]` — byte viewer with streaming Tutor explanations (unchanged)
-- `/build/[competencyId]` — **real in-browser build environment**: file tree, syntax editor, **Run/Test buttons that execute in a namespace sandbox and stream output to a read-only panel** (CUT-2 — no interactive shell), live telemetry status, live Lab feedback, per-learner variant task statement
-- `/defend/[competencyId]` — **live oral defense + live grading**: Examiner voice/typed dialogue, transcript + integrity signals, real rubric scores from the process trace
-
-The marketplace, employer, and admin surfaces are unchanged from v0.1/v0.2.
+1. **One-liner install (README quickstart):** `curl -fsSL https://git.coreci.dev/coreci/nextcraft/raw/main/scripts/install.sh | bash` — downloads the latest release's `nextcraft-linux-x64` binary, verifies its sha256, installs to `~/.local/bin`, prints a PATH hint if needed.
+2. **CLI commands:** `nextcraft doctor` (prereq checks), `nextcraft bootstrap` (fresh clone → runnable stack), `nextcraft verify` (health check), `nextcraft dev` (dev server passthrough), plus `--help`/`--version`.
+3. **Release surface:** every Gitea release from v0.3.2 onward carries `nextcraft-linux-x64` + `nextcraft-linux-x64.sha256` assets.
 
 ## Happy Path
 
-1. Learner opens `/build/comp-01` → a per-learner **variant statement** and starter files load; a namespace sandbox is created for the session
-2. Learner edits files in the tree and clicks **Run**/**Test** → commands execute in the sandbox and real output renders in the build panel; the telemetry sidebar pulses as events stream to ai-service and persist in SQLite
-3. The Lab panel streams feedback derived from the **live trace digest** (real commands, real failures)
-4. Learner opens `/defend/comp-01` → **Start Defense**: the Examiner streams an opening question ("Walk me through your build — why did you structure it this way?")
-5. Learner answers by voice (mic consent → MediaRecorder → STT) or typed fallback → examiner follow-ups probe the trace ("You hit three test failures before passing — what changed?"); TTS plays examiner audio (or browser speech in fallback)
-6. Learner finishes the defense → transcript + integrity signals appear; verdict renders in a GradeBadge
-7. Learner clicks **Grade My Work** → the grading engine computes the digest from the real trace, rubric-scores it, and the panel renders per-criterion bars + strengths/gaps/verdict
-8. Proctor banner shows integrity signals from the live trace + defense in coaching tone; Mentor panel on `/dashboard` can narrate the real outcome
-9. Navigating away destroys the sandbox (pool slot freed); killing ai-service shows inline error + retry states on every panel, with no crashes
+Before execution, the end-to-end scenario this milestone must make true:
+
+1. A consumer on a linux x64 box runs the one-liner; `nextcraft` lands in `~/.local/bin`.
+2. They clone the repo (or the CLI detects the repo root), run `nextcraft doctor` — all prerequisites report ✓ with actionable messages for any gap.
+3. `nextcraft bootstrap` — pnpm install, ai-service venv via the existing bootstrap.sh, `.env` created from `.env.example`, optional-key warnings (not blockers), mock providers keep the stack runnable keyless.
+4. `nextcraft verify` — venv imports, ports, env presence, build readiness all ✓.
+5. `nextcraft dev` — the dev stack runs; Ctrl+C stops it (passthrough semantics).
+6. On every ship, the Gitea release shows the binary + checksum assets; re-running the one-liner upgrades to the latest binary.
 
 ## UX Acceptance Criteria
 
-1. Run/Test output visibly reflects the real sandbox execution (command round-trip to the sandbox, real stdout/stderr), not a replay animation
-2. The learner path contains **no mock engine data** — scenarios, canned artifacts, and scripted defense transcripts from v0.2 are gone from runtime
-3. Variant statements visibly differ between two learner sessions on the same competency
-4. Mic permission flow is graceful: consent prompt, recording indicator, no-mic/typed fallback, and browser-native speech path when no server voice key is configured
-5. Defense transcript renders turn-by-turn with latency shown; integrity signals render in coaching (supportive) tone
-6. Grade results render as structured per-criterion bars with verdict, from the real trace — not from final-output-only heuristics
-7. Pool-full (503) shows an honest "environment busy — retry" state; navigation/unmount destroys sandboxes with no leaks
-8. When ai-service is unreachable: inline error + retry on every panel — no crashes, no console errors, no blank UI
-9. All new UI uses design tokens, supports dark mode, meets WCAG AA contrast, responsive at 375px / 768px / 1280px
-10. `pnpm build` and `pnpm typecheck` pass with zero errors; `pnpm ai:test` green cloud-free and voice-key-free
+- `doctor` output lists every prerequisite with ✓/✗ and a **fix hint** on every ✗; exit code 1 if any ✗, 0 otherwise.
+- `bootstrap` is **idempotent** — running twice produces the same end state, second run fast (no reinstalls where avoidable).
+- `bootstrap` never writes secrets, never blocks on missing optional keys — warns with the exact key names and where to set them.
+- `verify` gives a single-glance green/red summary; every red item names the failing command it ran.
+- Every command supports `--help`; unknown command/flag exits 2 with usage.
+- The one-liner **never hard-fails silently**: any error path (no release, no binary asset, checksum mismatch, platform mismatch) prints a specific message + the source-bootstrap alternative.
+- Checksum mismatch = hard stop + explicit "do not run this binary" message.
+- PATH hint: if `~/.local/bin` is not on PATH, the installer prints the exact export line to add.
+- Binary runs standalone on a box with node NOT installed (SEA self-containment) — `./nextcraft-linux-x64 --version` works.
+
+---
+
+## Phase 1: Bootstrap CLI Core
+
+**Requirements:** REQ-4-001, REQ-4-002
+**Goal:** `apps/cli` package with doctor/bootstrap/verify/dev fully working from source (`node dist` + pnpm bin), unit-tested, wired into the monorepo (turbo + root scripts), composing — not duplicating — the existing scripts.
+
+### Wave 1: Package foundation (parallel)
+
+#### Task 1-1-01: CLI package scaffold + entry + dispatch
+- **Persona:** cli-engineer — **REQ:** REQ-4-001
+- **Files:** `apps/cli/package.json`, `apps/cli/tsconfig.json`, `apps/cli/src/index.ts`, `apps/cli/src/commands/help.ts` (usage text), `apps/cli/tests/dispatch.test.ts`
+- **Action:** pnpm workspace package `@nextcraft/cli` (private, `"bin": {"nextcraft": "dist/index.js"}`). Entry: parse argv (hand-rolled, no runtime deps), dispatch to commands, `--help`/`-h`, `--version` (from package.json version), unknown → exit 2 with usage. Exit-code contract: 0 ok / 1 failure / 2 usage. shebang `#!/usr/bin/env node` on the built entry (esbuild banner in P2; for P1 `tsx` runs in dev via package script `"dev": "tsx src/index.ts"`).
+- **Verify:** `pnpm --filter @nextcraft/cli test` green (dispatch: routes doctor/bootstrap/verify/dev; unknown exits 2; --help exits 0; --version prints package version); `pnpm typecheck` green.
+
+#### Task 1-1-02: Checks library (pure logic)
+- **Persona:** cli-engineer — **REQ:** REQ-4-001, REQ-4-002
+- **Files:** `apps/cli/src/checks/check-command.ts`, `apps/cli/src/checks/check-env.ts`, `apps/cli/src/lib/log.ts`, `apps/cli/tests/checks.test.ts`
+- **Action:** `check-command`: given a name + optional `--version` probe + a min-version parser, resolve binary on PATH (`which`), semver-ish compare (major.minor tolerant), return `CheckResult {name, ok, found, version, hint}`. `check-env`: diff `.env.example` template keys vs an existing `.env` (missing keys → warn-classified; required-vs-optional classification table from the template's own comments + a static required list of zero keys — all optional per A-210), return per-key results. `log.ts`: `ok(msg)`, `fail(msg, hint)`, `warn(msg)`, `info(msg)` formatters with symbols and consistent alignment. Pure functions — no side effects at import; fs access injected as parameters for testability.
+- **Verify:** unit tests green: version compare (>= boundaries), missing binary → ok:false + hint, env diff missing/new/extra keys, required-optional classification.
+
+#### Task 1-1-03: Root + turbo wiring
+- **Persona:** backend-engineer — **REQ:** REQ-4-002
+- **Files:** root `package.json` (update), `turbo.json` (update), `pnpm-workspace.yaml` (verify apps/* already covered — no change expected)
+- **Action:** Add `cli:dev`, `cli:test`, `cli:build`, `cli:typecheck`, `cli:lint` root scripts mirroring the `ai:*` passthrough pattern (D-022/D-037). Turbo tasks for the CLI package: `build` (dependsOn `^build`, outputs `dist/**`), `test`, `typecheck`, `lint` (cache:false, outputs:[] for test — same shape as ai-service). No changes to existing ai:* tasks.
+- **Verify:** `pnpm cli:test` + `pnpm cli:typecheck` green from repo root; `pnpm build` still green for web+ai-service (turbo graph unaffected); `pnpm ai:test` still green.
+
+### Wave 2: Commands (depends on Wave 1)
+
+#### Task 1-2-01: doctor command
+- **Persona:** cli-engineer — **REQ:** REQ-4-001
+- **Files:** `apps/cli/src/commands/doctor.ts`, `apps/cli/tests/doctor.test.ts`
+- **Action:** Checks (each with actionable hint): node ≥18 (`process.version`), pnpm ≥8 on PATH (`pnpm --version`), python3 ≥3.11 (`python3 --version` parse), git (`git --version`), corepack available-or-pnpm-present nuance folded into pnpm check, `unshare` binary on PATH (`which unshare` — sandbox fabric needs it; hint explains what breaks without it). Sequential execution with per-check timeout; summary line; exit 1 if any ✗. Runs from any cwd (no repo required — pure environment check).
+- **Verify:** unit tests with injected spawn results: all-pass → exit 0 + summary; missing pnpm → ✗ + hint + exit 1; missing unshare → ✗ with sandbox-specific hint.
+
+#### Task 1-2-02: bootstrap command
+- **Persona:** cli-engineer — **REQ:** REQ-4-002
+- **Files:** `apps/cli/src/commands/bootstrap.ts`, `apps/cli/src/lib/spawn.ts`, `apps/cli/tests/bootstrap.test.ts`
+- **Action:** `spawn.ts`: `run(cmd, args, {timeoutMs, cwd, env})` — promisified child_process.spawn, inherited stdio, timeout kill (SIGTERM→SIGKILL escalation), returns `{code}`; throws never (codes always returned). `bootstrap.ts` steps (each logged before/after): (1) locate repo root (walk up for pnpm-workspace.yaml; error with hint if not in a clone); (2) `pnpm install` at root; (3) delegate ai-service venv to `apps/ai-service/scripts/bootstrap.sh` via spawn with generous timeout (10 min) — **zero pip/venv logic in the CLI** (A-202); (4) copy `.env.example` → `.env` if absent (preserve existing; report created vs kept); (5) validate optional keys in `.env` vs template — warn-only (A-210); never touch `.ciagent/.env.secrets`; (6) print next-steps (`nextcraft verify`, `nextcraft dev`). Idempotent: every step safe to re-run.
+- **Verify:** unit tests with stub spawn: step order, env copy semantics (absent → create, present → keep), timeout path returns failure code, secrets file never written; `pnpm cli:test` green.
+
+#### Task 1-2-03: verify + dev commands
+- **Persona:** cli-engineer — **REQ:** REQ-4-002
+- **Files:** `apps/cli/src/commands/verify.ts`, `apps/cli/src/commands/dev.ts`, `apps/cli/tests/verify.test.ts`
+- **Action:** `verify.ts` health checks (each runnable + reported): ai-service venv python imports (`import ai_service` via venv python), uvicorn present in venv, ports 3000/8420 free (net stat via node), `.env` exists with AI_PORT parseable, `pnpm build` dry readiness (turbo graph parses — run `turbo build --dry=json` cheap check or typecheck-only default; choose the cheap one). Summary + exit code. `dev.ts`: locate repo root, exec passthrough to `apps/ai-service/scripts/dev.sh` with **inherited stdio and signals** (Ctrl+C semantics), no timeout (long-running); document that web dev server runs via `pnpm dev` separately (dev.sh owns ai-service only).
+- **Verify:** unit tests: verify aggregates check results → exit codes; dev spawns dev.sh with signal passthrough assertions (mock spawn).
+
+### Wave 3: Integration review (depends on Wave 2)
+
+#### Task 1-3-01: CLI security + integration review pass
+- **Persona:** security-auditor — **REQ:** REQ-4-001, REQ-4-002
+- **Files:** `apps/cli/src/lib/spawn.ts` (review; patch if defect), `apps/cli/src/commands/bootstrap.ts` (review), `apps/cli/tests/**` (add regression if defect found)
+- **Action:** STRIDE pass on the CLI surface: spawn injection (args never through shell string — array form only), timeout enforcement, secrets never logged, env template copy doesn't overwrite user edits, no shell=true anywhere, PATH resolution honest errors. Findings → P0 patches now with regression tests; P1+ noted for final-phase review.
+- **Verify:** `pnpm cli:test` green incl. any added regressions; `grep -rn "shell: *true" apps/cli/src` returns nothing.
+
+### Must-Haves (Phase 1)
+- [ ] `pnpm --filter @nextcraft/cli test` green; `pnpm typecheck` green; `pnpm build` green
+- [ ] doctor: every prerequisite reported with ✓/✗ + actionable hint; exit 1 on any ✗; runs outside a repo clone
+- [ ] bootstrap: composes scripts/bootstrap.sh (no pip/venv logic in CLI); idempotent; .env created from template only when absent; optional-key warnings, never blocks; never writes secrets
+- [ ] verify: venv import + uvicorn + ports + env checks with single-glance summary and named failing commands
+- [ ] dev: passthrough with signal inheritance (Ctrl+C stops the stack)

+
+## Phase 2: Binary Build + Release Pipeline
+
+**Requirements:** REQ-4-003, REQ-4-004
+**Goal:** `nextcraft-linux-x64` SEA binary + sha256 sidecar built reproducibly from the CLI package; one-liner `install.sh` verified end-to-end against a real release; release-asset upload wired so **every ship from now on carries binaries**.
+
+### Wave 1: Binary build (parallel)
+
+#### Task 2-1-01: SEA binary build script (G-101: live-build probe FIRST — mechanism must be proven before the pipeline depends on it)
+- **Persona:** cli-engineer — **REQ:** REQ-4-004
+- **Files:** `apps/cli/scripts/build-binary.mjs`, `apps/cli/package.json` (add `build:binary` script), `apps/cli/.sea-config.json` (or generated in-script)
+- **Action:** **First action of this task: build one real SEA binary end-to-end and run it** (`--version` + `doctor` smoke) before writing the polished script.** Pipeline: esbuild bundle `src/index.ts` → `dist/bundle.cjs` (platform node, target node18, banner shebang, SEA config: `{main: "dist/bundle.cjs", output: "dist/sea-prep.blob", disableExperimentalSEAWarning: true}`) → `node --experimental-sea-config` → copy system node binary → inject blob (`npx postject` with sentinel `NODE_SEA_BLOB_FUSE` fuse, or `dd` fallback) → chmod +x → `dist/nextcraft-linux-x64` → **stamp version from the shipping tag argument** (`NEXTCRAFT_VERSION` injected via esbuild `define`, G-102 — `--version` prints it; absent arg → dev stamp `0.0.0-dev`) → `shasum -a 256` → `dist/nextcraft-linux-x64.sha256`. Fallback (documented, scripted, honest): if SEA injection fails, python3 zipapp builds `nextcraft-linux-x64.pyz` (requires python3 on target — install.sh handles both asset shapes and the docs say so; NO silent claim of node-less operation, G-101).
+- **Verify:** `pnpm --filter @nextcraft/cli build:binary` produces the binary; `./dist/nextcraft-linux-x64 --version` runs **with node absent from PATH** (test via `env -i /bin/sh -c 'PATH=/usr/bin:/bin ...'` sandbox or by temporarily stripping PATH in a subprocess test); sha256 file matches `shasum -c`.
+
+#### Task 2-1-02: Release-asset upload helper
+- **Persona:** cli-engineer — **REQ:** REQ-4-004
+- **Files:** `scripts/release-assets.sh`, `apps/cli/tests/release-assets.test.ts` (fixture-level)
+- **Action:** Given a tag: build binary (Task 2-1-01), resolve GITEA_TOKEN from `.env`/`.env.secrets`/`.env.*` **via the secrets loader only** (never shell env — v1.8 root cause), create/locate the Gitea release via API, upload both assets (`POST /api/v1/repos/{owner}/{repo}/releases/{id}/assets?name=...` multipart). Bounded retry (3) per config.ship.max_release_retries; token never echoed; failure = non-blocking escalation message (release_pending semantics) — tag+merge already complete the ship.
+- **Verify:** fixture test: token resolution order (.env.secrets wins over .env; shell env NEVER consulted — assert with a poisoned env var fixture); dry-run mode prints the exact curl-multipart it would send (no net in tests).
+
+#### Task 2-1-03: install.sh one-liner
+- **Persona:** cli-engineer — **REQ:** REQ-4-003
+- **Files:** `scripts/install.sh`, `apps/cli/tests/install-script.test.ts`
+- **Action:** POSIX sh (no bashisms — dash-safe): `set -eu`; platform check (uname linux + x86_64; else print source-bootstrap path + exit 0 — a graceful no-op, not an error); resolve latest release via Gitea API (`curl -fsSL .../releases/latest`, parse `tag_name` + asset `browser_download_url`s with sed/grep — no jq dependency); **match assets by EXACT name** (`nextcraft-linux-x64`, `nextcraft-linux-x64.sha256` — any parse/lookup miss = degrade to source-bootstrap instructions, exit 0, G-103 — never a name-approximate install); handle the zipapp asset shape (`nextcraft-linux-x64.pyz` + sidecar) when the binary is absent, printing the python3 requirement honestly; download both assets to `mktemp -d` (trap cleanup EXIT); **verify sha256 before anything else** (`shasum -a 256 -c` or sha256sum); on mismatch → hard stop, explicit "do not run" message, exit 1; install to `~/.local/bin` (mkdir -p; `--dest` override); PATH hint when missing (print exact export line); print the binary's own `--version` output (G-102: must equal the resolved release tag — mismatch = install-time integrity stop) + `nextcraft doctor` next-step. No-binary-asset path: print the git-clone + scripts/bootstrap.sh instructions + exit 0. Zero secrets required (public release assets).
+- **Verify:** unit tests over the script's pure helpers extracted where feasible; **live E2E in Task 2-3-01**. `sh -n scripts/install.sh` syntax-clean; `dash scripts/install.sh --help` safe if dash present.
+
+### Wave 2: Ship-flow integration (depends on Wave 1)
+
+#### Task 2-2-01: Wire binaries into every ship (G-104: enforcement, not prose)
+- **Persona:** backend-engineer — **REQ:** REQ-4-004
+- **Files:** `.ciagent/config.json` (no schema change needed — release section already configured), this repo's ship procedure notes (update `.ciagent/ARCHITECTURE.md` Build Order note if needed), `scripts/release-assets.sh` (finalize from 2-1-02)
+- **Action:** Establish the ship-time contract going forward: after every phase ship (tag + merge complete = ship gate per config.ship), run `scripts/release-assets.sh <tag>` to attach binary + checksum to the freshly created release. **G-104:** this run is MANDATORY-ATTEMPTED on every release from v0.3.2 onward — best-effort/non-blocking like release creation (release_pending escalation on exhaustion), logged in the ship commit, and the P4 final audit gate includes "milestone release carries both assets" as an explicit check. This makes "ongoing binaries" a property of the pipeline, not a one-off.
+- **Verify:** The P2 ship itself executes the step against tag v0.3.2 (live validation — see Ship).
+
+### Wave 3: End-to-end validation (depends on Wave 2)
+
+#### Task 2-3-01: Install E2E against the live release
+- **Persona:** security-auditor — **REQ:** REQ-4-003
+- **Files:** `apps/cli/tests/install-e2e.test.ts` (marked slow/e2e), `apps/cli/README.md` (install internals section)
+- **Action:** Live E2E after the v0.3.2 release exists (run post-ship, documented as the verify gate for this phase's asset path): fresh HOME tmpdir → run install.sh → assert binary at `$HOME/.local/bin/nextcraft`, `--version` output equals the release tag (G-102 integrity assertion), checksum verified path taken (tamper test: flip a byte in a local fixture download → script refuses + exits 1). Record the transcript in the phase verify commit. If the live release isn't reachable at verify time, run the full local equivalent (serve assets from a fixture dir via `python3 -m http.server` + FORGE_BASE override) and mark live re-check as a P1 follow-up.
+- **Verify:** E2E green locally (fixture server path mandatory in tests — no test depends on the live forge); tamper-rejection proven; transcript recorded.
+
+### Must-Haves (Phase 2)
+- [ ] **G-101:** a real SEA binary built + smoke-run BEFORE the pipeline depends on it; if SEA fails, zipapp is primary and docs state the python3 requirement
+- [ ] **G-102:** binary `--version` reports the shipping tag (stamped at build); install E2E asserts version == release tag
+- [ ] `pnpm --filter @nextcraft/cli build:binary` produces `nextcraft-linux-x64` + `.sha256`; binary runs without node on PATH (`--version`, `doctor` smoke)
+- [ ] **G-103:** `sh -n scripts/install.sh` clean; dash-safe; exact-name asset matching; platform mismatch → graceful source-bootstrap path (exit 0)
+- [ ] Checksum verified before install; tamper → hard stop with explicit warning (E2E-proven)
+- [ ] install.sh resolves latest release + assets from the Gitea API with zero secrets and no jq
+- [ ] release-assets.sh resolves GITEA_TOKEN from .env* files only (never shell env — tested with poisoned env)
+- [ ] **G-104:** v0.3.2 release carries both assets (live validation at ship); upload failure is non-blocking escalation, attempted + logged every release
+- [ ] `pnpm build`, `pnpm typecheck`, `pnpm cli:test` all green
+
+---
+
+## Phase 3: Install Docs + Fresh-Clone E2E
+
+**Requirements:** REQ-4-005
+**Goal:** README quickstart + CLI reference matching the tested reality exactly, plus a fresh-clone E2E test proving the happy path end-to-end.
+
+### Wave 1: Fresh-clone E2E (drives doc accuracy)
+
+#### Task 3-1-01: Fresh-clone bootstrap E2E
+- **Persona:** cli-engineer — **REQ:** REQ-4-005
+- **Files:** `apps/cli/tests/fresh-clone-e2e.test.ts` (slow/e2e-marked)
+- **Action:** In a `mktemp -d` sandbox: `git clone` the repo locally (file:// clone of HEAD — no network), run `pnpm --filter @nextcraft/cli dev -- doctor` (or the built binary from P2) → then `bootstrap` → then `verify`, asserting each step's exit codes and key output markers. Skips gracefully when network-dependent steps are unavailable (CI marker). Documents the exact happy path the README will state.
+- **Verify:** E2E green locally (clone of the working tree); output transcript matches README claims (cross-checked in 3-2-01).
+
+### Wave 2: Documentation (depends on Wave 1 transcript)
+
+#### Task 3-2-01: README quickstart + CLI reference
+- **Persona:** backend-engineer — **REQ:** REQ-4-005
+- **Files:** root `README.md` (update quickstart section), `apps/cli/README.md` (CLI reference)
+- **Action:** Root README quickstart: the one-liner (exact tested URL), then doctor → bootstrap → verify → dev sequence with expected outputs; source-bootstrap alternative documented (clone + scripts). apps/cli README: every command, flags, exit codes, the env-template copy semantics, optional-key warning semantics, secrets policy (never generated/committed; .ciagent/.env.secrets location), binary install internals, troubleshooting table keyed to actual failure modes observed in E2E.
+- **Verify:** Every command line in both READMEs is copy-paste runnable — verified against the 3-1-01 transcript; doc drift check: no references to commands/flags that don't exist in `--help` output.
+
+### Must-Haves (Phase 3)
+- [ ] Fresh-clone E2E green: doctor → bootstrap → verify sequence from a clean clone
+- [ ] README quickstart matches the E2E transcript exactly (no aspirational docs)
+- [ ] CLI reference covers all 4 commands + --help/--version + exit codes
+- [ ] `pnpm build`, `pnpm typecheck`, `pnpm test` (all suites) green
+
+---
+
+## Phase 4: Final Review + Ship (milestone release v0.3.4)
+
+1. Branch gate → `phase/04-final-review-ship`.
+2. Multi-persona review across the milestone (correctness, testing, security, performance, maintainability, adversarial) — P0 auto-fixed, P1+ fixed in this phase.
+3. Audit: reconstruction test (.ciagent files ↔ git log), file discipline, branch hygiene, commit discipline, P0-review flags resolved, **G-104 gate: milestone release v0.3.4 carries `nextcraft-linux-x64` + `.sha256` assets**.
+4. Milestone ship: merge phase/04 → milestone/v0.4-distribution; merge milestone → main; tag **v0.3.4** (= milestone release); attach binary + checksum assets (the ongoing-binaries contract); release notes with full milestone summary (all phases, all REQ-4-001..005, the "ongoing binaries from now on" statement, v0.5 deferral list per D-016); delete all milestone/phase branches.
+5. Complete: REQUIREMENTS.md REQ-4-001..005 → complete; ROADMAP.md v0.4 → complete; checkpoint cleared.
+
+## Must-Haves (Milestone)
+- [ ] One-liner installs a working binary from the live Gitea release (E2E-proven, tamper-tested)
+- [ ] Fresh clone → doctor → bootstrap → verify → dev: the full happy path green from a clean environment
+- [ ] Every release from v0.3.2 onward carries `nextcraft-linux-x64` + `.sha256` assets
+- [ ] Zero runtime npm deps in the CLI; secrets only ever from .env* files; never in code/logs/commits
+- [ ] All suites green: `pnpm build`, `pnpm typecheck`, `pnpm ai:test`, `pnpm cli:test`

-**Scope:** Replace v0.2's mock engine inputs with real credential engines. Build the sandbox fabric (sandboxed IDE / design tool / simulation), the live in-environment build-telemetry pipeline, the process-trace grading engine, per-learner variant task generation, and the oral/voice defense with AI examiner. Lab/Assessor/Proctor agents move from mock inputs to real engine inputs; the six tutor agents operate on authentic telemetry and artifacts.
+**Scope (deferred seams from D-016, to be specified at v0.5 Phase 0):** real server STT/TTS (`openai-audio` voice provider, CUT-1/G-7 seam), KYC/identity verification + age-gating backend (REQ-F-017), design/simulation sandbox environments (REQ-F-021 remainder), exec-telemetry seq-lease/replay-margin fix.
+
+## Prior Milestone: v0.4 — Distribution & Bootstrap CLI (COMPLETE, shipped as v0.3.4)
+
+**Scope (founder directive, 2026-09-12):** Streamline installing Nextcraft. Ship a bootstrap CLI with a single-liner install script, and publish release binaries on an ongoing basis for every release going forward.
+
+**Delivered:** `nextcraft` CLI — `doctor` (prerequisite checks), `bootstrap` (deps + venv + env from templates + key validation), `verify` (health check), `dev` (thin passthrough to scripts/dev.sh); one-liner install script downloading the linux x64 binary from the latest Gitea release with sha256 + version integrity gates; binary release pipeline attached to every ship from v0.3.2 onward; install/quickstart documentation backed by a fresh-clone E2E test. All 5 requirements (REQ-4-001..005) complete.
+
+**Status of v0.3:** Complete and shipped (v0.2.8). Credential engines live: namespace-isolated sandbox fabric, live build telemetry, process-trace grading, seeded variants, oral defense; real learner build/defense/grading surfaces.
 
 **Status of v0.2:** Complete and shipped (v0.2.0). Six AI tutor agents live over mockengine inputs (D-015).
 
-**Deferred from earlier plan:** REQ-F-017 (identity verification + 16+/18+ age-gating) is explicitly deferred to a later milestone per founder directive. Age-gating remains the v0.1-style visual flow mockup; no real KYC backend is built in v0.3.

+All 5 v0.4 requirements (REQ-4-001..005) are complete and shipped as v0.3.4:
+1. Bootstrap CLI — `nextcraft` executable with `doctor` / `bootstrap` / `verify` / `dev` (REQ-4-001, REQ-4-002)
+2. One-liner install — `curl | sh` fetching the linux x64 binary from the latest Gitea release with sha256 + version integrity verification (REQ-4-003)
+3. Ongoing release binaries — every release from v0.3.2 onward ships the CLI binary + checksum as release assets (REQ-4-004)
+4. Install documentation — README quickstart + CLI reference verified by a fresh-clone E2E test (REQ-4-005)
 
-1. Sandbox fabric — sandboxed IDE, design tool, and simulation environments with isolated execution and lifecycle management (REQ-F-021)
-2. Live build telemetry — in-environment capture of process events (keystrokes, commands, file diffs, run/test results) streamed to ai-service (REQ-F-010)
-3. Process-trace grading engine — grade artifacts from their process traces, not just final output (REQ-F-007); feeds the Assessor agent real inputs
-4. Variant task generation — per-learner task variants so no two learners receive identical prompts (REQ-F-008)
-5. Oral/voice defense — AI examiner conducts spoken defense of submitted work (REQ-F-009); feeds the Proctor/Mentor agents
-6. Agent re-grounding — Lab/Assessor/Proctor consume real engine inputs (telemetry, traces, defenses) instead of v0.2 mocks

+| A-203 | Where does the one-liner fetch the binary? | **Gitea latest-release API** (`/repos/{owner}/{repo}/releases/latest`) → download `nextcraft-linux-x64` + `.sha256` asset; repo raw serves `install.sh` as the stable URL | 0.80 |

+| A-205 | Binary "ongoing releases" scope? | **Every ship from v0.4 onward** attaches `nextcraft-linux-x64` + sha256 sidecar to the Gitea release — the ship workflow gains an asset step; retroactive binaries for old releases NOT required | 0.90 |
+| A-206 | No binary available yet / non-linux? | **Graceful degradation**: install script prints source-bootstrap instructions (git clone + scripts/bootstrap.sh) — never a hard fail | 0.88 |
+| A-207 | Checksum trust root? | **sha256 sidecar shipped as a release asset next to the binary** (same release, same channel); script verifies download against it. Signature/PKI out of scope for v0.4 (single forge, TLS transport) | 0.75 |
+| A-208 | Which prerequisites does doctor check? | node ≥18, pnpm ≥8, python3 ≥3.11, git, `unshare` availability (sandbox fabric needs it) — versions from the existing bootstrap tooling, not invented | 0.85 |
+| A-209 | Does `dev` manage multiple processes? | **No.** Thin passthrough to scripts/dev.sh only — the CLI stays bootstrap-scoped (D-016); orchestration remains in dev.sh | 0.82 |
+| A-210 | `.env.secrets` handling by bootstrap? | **Template copy only for `.env.example` → `.env`; secrets NEVER generated, NEVER committed; bootstrap validates presence of optional keys and warns (not blocks) when missing — mock-first providers keep the stack runnable** | 0.90 |

 ### Phase 0: Pre-execution
 
-**Goal:** Establish v0.3 specification, clarify ambiguities, research credential-engine architecture (sandbox isolation, telemetry transport, trace grading, variant generation, voice IO), create detailed plans.
+**Goal:** Establish v0.4 specification (founder directive D-016), clarify ambiguities, research the binary toolchain + Gitea release-asset API + existing bootstrap scripts, create detailed plans, grill adversarially.
 
 **Stages:** SPECIFY → CLARIFY → RESEARCH → PLAN → GRILL → MVP/UX CHECK → SHIP
 
 **Deliverables:**
 - Updated .ciagent/config.json, PROJECT.md, REQUIREMENTS.md, ROADMAP.md, ARCHITECTURE.md, PERSONAS.md, PLAN.md
 
-**Success criteria:** All .ciagent/ files updated for v0.3; phase 0 shipped as first v0.2.x patch.
+**Success criteria:** All .ciagent/ files updated for v0.4; phase 0 shipped as v0.3.0.

-### Phase 1: Sandbox Fabric
+### Phase 1: Bootstrap CLI Core
 
-**Goal:** Provision and manage isolated per-learner execution environments.
+**Goal:** A working `nextcraft` CLI with doctor/bootstrap/verify/dev commands, unit-tested against the real monorepo.
 
-**Requirements:** REQ-3-001, REQ-3-002
+**Requirements:** REQ-4-001, REQ-4-002
 
 **Key deliverables:**
-- Sandbox orchestrator service: create/list/destroy/snapshot sandbox instances (coding IDE — design tool and simulation environments deferred to v0.4 per D-025)
-- Isolation boundary: per-learner Linux user/mount/pid/net namespace subprocess isolation (`unshare`, D-024); no cross-tenant filesystem/network access
-- Resource limits: CPU/memory/single-file-size quotas (rlimits) + wall-clock timeout reaper + best-effort workdir-size sweep; per-sandbox pids + hard disk quota accepted as v0.3 gaps (G-1/G-2)
-- Sandbox lifecycle API consumed by ai-service and the web learner surface
+- `apps/cli` package: `nextcraft` executable (source-runnable in dev, binary-built in P2)
+- `doctor`: checks node ≥18, pnpm, python3 ≥3.11, git, unshare availability — actionable errors, exit codes
+- `bootstrap`: idempotent — pnpm install, ai-service venv + pinned deps (reuses scripts/bootstrap.sh logic), .env from .env.example templates, key validation (warnings not blockers for optional keys), .env.secrets handling
+- `verify`: health check — venv imports, pnpm build readiness, ports free, env vars present
+- `dev`: thin passthrough to scripts/dev.sh (no orchestration logic duplicated)
+- Unit tests: doctor/bootstrap parsing + command dispatch, against fixtures (never modifying the real repo state)
 
 **Success criteria:**
-- A sandbox can be created, written to, snapshotted, and destroyed via API
-- Isolation verified: a sandbox cannot read another learner's data
-- Resource limits enforced and observable — enforcement mechanism: rlimits (memory/CPU) + wall-clock reaper + workdir-size sweep; per-sandbox pids and hard-disk-quota are accepted v0.3 gaps (no cgroup delegation/sudo on this box, G-1)
+- `nextcraft doctor` reports each prerequisite with actionable guidance
+- `nextcraft bootstrap` on a fresh clone reaches a state where `verify` passes
+- All commands have `--help`, exit non-zero on failure, no shell-out without timeout
+- `pnpm build`, `pnpm typecheck`, `pnpm ai:test` green
 
 ---
 
-### Phase 2: Live Build Telemetry
+### Phase 2: Binary Build + Release Pipeline
 
-**Goal:** Capture in-environment process events and stream them to ai-service reliably.
+**Goal:** Reproducible linux x64 binary + one-liner install + release-asset upload wired into the ship flow.
 
-**Requirements:** REQ-3-003
+**Requirements:** REQ-4-003, REQ-4-004
 
 **Key deliverables:**
-- Telemetry capture agent (in-sandbox): commands, file diffs, run/test results, keystroke-level/activity events
-- Telemetry transport: durable, ordered, resumable stream to ai-service ingestion endpoint
-- Trace persistence: per-learner, per-task process traces stored for grading and proctoring
-- Transport hardening: retries, backpressure, exactly-once-or-at-least-once semantics documented
+- Build script producing `nextcraft-linux-x64` + `nextcraft-linux-x64.sha256` (toolchain probe-verified at RESEARCH; embedded script assets)
+- One-liner install script `install.sh` served from the repo: detect linux x64, resolve latest release via Gitea API, download + verify checksum, install to `~/.local/bin`, PATH hint, source-bootstrap fallback when no binary/asset
+- Ship integration: every release from v0.4 onward attaches the binary + checksum as release assets (the "ongoing binaries" requirement)
+- Asset-upload helper using the Gitea token from `.env*` files only (never shell env)
 
 **Success criteria:**
-- Sandbox activity produces a complete ordered process trace in ai-service
-- Stream survives transient network failure without trace loss
-- Trace retrievable by learner+task ID for grading
+- Binary runs on this box: `./nextcraft-linux-x64 doctor` green against the repo
+- Install script verified end-to-end against the real Gitea release (or local dry-run if release pending)
+- Checksum verification rejects a corrupted download (tested)
+- Release assets present on the phase ship
 
 ---
 
-### Phase 3: Process-Trace Grading Engine
+### Phase 3: Install Docs + Fresh-Clone E2E
 
-**Goal:** Grade learner artifacts from their full process traces.
+**Goal:** Documentation and end-to-end proof that a fresh consumer reaches a running stack via the one-liner.
 
-**Requirements:** REQ-3-004
+**Requirements:** REQ-4-005
 
 **Key deliverables:**
-- Trace analyzer: reconstructs build/decision timeline from a process trace
-- Grading engine: rubric-aligned scoring over the trace (process quality, not just final artifact)
-- Structured score output consumable by the Assessor agent
-- Calibration against v0.2 mock corpora to validate grading dimensions
+- README quickstart: one-liner → `nextcraft doctor` → `nextcraft bootstrap` → `nextcraft dev`
+- CLI command reference (all flags, exit codes)
+- Fresh-clone E2E test: clean temp clone → doctor → bootstrap → verify → build green (sandboxed; no network beyond package registries already used)
+- Install-script docs: prerequisites, offline/manual install, troubleshooting
 
 **Success criteria:**
-- Engine emits structured rubric-aligned scores from a real process trace
-- Scores distinguish process quality (e.g., iterative debugging vs. paste-and-run)
-- Output feeds Assessor; replaces pre-baked artifact corpus inputs
+- A fresh clone bootstraps to a passing `verify` with one command sequence
+- README quickstart matches the actual tested flow exactly
+- E2E test green in CI-equivalent local run

-**Key deliverables:**
-- Variant generator: parameterized task templates → unique per-learner instances
-- Variant seed registry: record variant parameters for grading fairness and proctoring

-### Phase 5: Oral / Voice Defense
-
-**Goal:** AI examiner conducts a spoken defense of the learner's submitted work.
-
-**Requirements:** REQ-3-006
-
-**Key deliverables:**
-- Voice pipeline: STT → defense dialogue (LLM examiner) → TTS
-- Examiner agent: probes understanding, challenges process choices from the trace
-- Transcript + integrity signals captured for Proctor/Mentor
-- Latency budget: defense feels conversational (bounded turn latency)
-
-**Success criteria:**
-- A spoken defense runs end-to-end (speak → examiner question → learner response → verdict)
-- Transcript + integrity signals persisted and consumable by Proctor
-- Turn latency within the documented budget
-
----
-
-### Phase 6: Agent Re-grounding + Learner Surface Integration
-
-**Goal:** Move Lab/Assessor/Proctor to real engine inputs; wire learner surface to the real engines.
-
-**Requirements:** REQ-3-007, REQ-3-008
-
-**Key deliverables:**
-- Lab agent consumes live sandbox telemetry (replaces v0.2 mock telemetry)
-- Assessor agent consumes grading-engine output (replaces pre-baked artifacts)
-- Proctor consumes telemetry + defense integrity signals (replaces mock telemetry)
-- Learner sandbox mockup → real in-browser build/run; assessment mockup → live defense + live grading
-
-**Success criteria:**
-- Lab/Assessor/Proctor operate on real inputs with no mock fallback in the learner path
-- Learner can build in-browser and see live telemetry + live feedback
-- Assessment surface runs a live defense and shows live grading
-- `pnpm build` and `pnpm typecheck` pass

-### Phase 7: Final Review + Ship
-
-**Goal:** Code review, audit, milestone release.
+**Goal:** Code review, audit, milestone release with binary assets.
 
 **Key deliverables:**
 - Multi-persona code review (correctness, testing, security, performance, maintainability)
 - Project health audit (reconstruction test, .ciagent/ file discipline, branch hygiene, commit discipline)
-- Milestone ship: merge milestone → main, tag final v0.2.x patch, create Gitea release
+- Milestone ship: merge milestone → main, tag final v0.3.x patch, create Gitea release WITH binary + checksum assets, verify assets downloadable
 
 **Success criteria:**
 - Code review: P0 fixes applied, P1+ documented
 - Audit: all checks pass, project state reconstructable from git log
-- Ship: milestone tagged, branch merged to main, Gitea release created — release note states identity/age-gating (KYC) is deferred and age-gating remains a visual mockup
-- All v0.3 requirements marked complete
+- Ship: milestone tagged, branch merged to main, Gitea release created with `nextcraft-linux-x64` + `.sha256` assets attached — the first of the ongoing binary releases

 AI-native outcome school + marketplace — graduates prove what they can build, not what they can write.
 
+## Quickstart
+
+One-liner install (linux x64):
+
+```sh
+curl -fsSL https://git.coreci.dev/coreci/nextcraft/raw/main/scripts/install.sh | sh
+```
+
+That downloads the latest release's `nextcraft` CLI binary, verifies its sha256 checksum, and installs it to `~/.local/bin` (PATH hint printed if needed). Every release ships fresh binaries — re-run the one-liner to upgrade.
+
+Then, from a clone of this repo:
+
+```sh
+nextcraft doctor      # check prerequisites: node >= 18, pnpm >= 8, python3 >= 3.11, git, unshare
+nextcraft bootstrap   # pnpm install + ai-service venv + .env from template (idempotent)
+nextcraft verify      # health check: venv imports, uvicorn, ports, env
+nextcraft dev         # run the ai-service dev server on :8420 (web dev server: pnpm dev)
+```
+
+The E2E test (`apps/cli/tests/fresh-clone-e2e.test.ts`) proves this exact sequence on a fresh clone.
+
+### No binary / non-linux?
+
+The installer degrades to printed source instructions. Manual equivalent:
+
+```sh
+git clone https://git.coreci.dev/coreci/nextcraft.git && cd nextcraft
+pnpm install
+bash apps/ai-service/scripts/bootstrap.sh
+cp apps/ai-service/.env.example apps/ai-service/.env
+pnpm ai:dev
+```

+| Command | What it does | Exit codes |
+|---------|--------------|------------|
+| `doctor` | Checks prerequisites on PATH: node >= 18, pnpm >= 8, python3 >= 3.11, git, unshare (sandbox fabric). Every ✗ prints a fix hint. | 0 all pass, 1 any fail |
+| `bootstrap` | Sets up the monorepo from a fresh clone: (1) locates the repo root, (2) `pnpm install`, (3) ai-service venv via `apps/ai-service/scripts/bootstrap.sh`, (4) copies `.env.example` → `.env` if absent, (5) warns on missing optional keys. Idempotent — safe to re-run. | 0 ok, 1 step failed |
+| `verify` | Health check: ai-service venv + `import ai_service`, uvicorn importable, `.env` present (warn-only), `AI_PORT` (default 8420) free, workspace `node_modules` present. | 0 ok, 1 failures |
+| `dev` | Thin passthrough to `apps/ai-service/scripts/dev.sh` (exports secrets from `.ciagent/.env.secrets` if present, runs uvicorn on :8420). Ctrl+C stops it. The web dev server is separate: `pnpm dev`. | child's exit code |
+| `--help` / `-h` | Usage for the CLI or any command. | 0 |
+| `--version` | Prints the version this binary was built as (matches the release tag). | 0 |
+
+Exit-code contract: `0` success, `1` check/step failure (hint printed), `2` usage error.
+
+### Remote server
+
+`nextcraft dev` binds the API on **0.0.0.0:8420** (and `pnpm dev` serves the web app on all interfaces), so the stack works from other machines out of the box:
+
+- Browse `http://<your-host>:3000` — the web app targets `http://<your-host>:8420` automatically (derived from the browser's hostname).
+- CORS admits any origin (`AI_CORS_ORIGINS=*` in `apps/ai-service/.env`). This is safe **only** because credentials are never enabled; to restrict, set an explicit list: `AI_CORS_ORIGINS=http://<your-host>:3000`.
+- To revert to loopback-only: `AI_HOST=127.0.0.1` in `apps/ai-service/.env`.
+- Security note: this is an unauthenticated dev API reachable from any network the box exposes. Mitigations that still apply: per-learner sandbox caps + global rate caps + learner allowlist (G-5), telemetry flood control (traces marked `INCOMPLETE_FLOODED` are refused by the grader). Expose only on trusted networks until identity/KYC lands (v0.5).

+# @nextcraft/cli — nextcraft
+
+The bootstrap CLI for the Nextcraft monorepo, shipped as a self-contained linux x64 binary (Node SEA) on every release.
+
+## Commands
+
+See the [root README quickstart](../../README.md) for the user-facing flow. Internals:
+
+- `src/index.ts` — argv dispatch, exit-code contract (0 ok / 1 failure / 2 usage), direct-run guard (`argv[0] === argv[1]` detects SEA context — the installer renames the binary, so filename matching is unreliable)
+- `src/commands/` — doctor / bootstrap / verify / dev; all orchestration delegates to `apps/ai-service/scripts/*.sh` via `src/lib/spawn.ts` (array-args only, SIGTERM→SIGKILL timeout ladder)
+- `src/checks/` — pure logic: version compare, `.env` template diff
+- `tests/` — node:test suites: dispatch, checks, spawn, command stubs, real-box doctor integration, install.sh fixture-server E2E (tamper rejection, degradation), release-assets token isolation, fresh-clone E2E
+
+## Build
+
+```sh
+pnpm cli:typecheck          # tsc --noEmit
+pnpm cli:test               # node:test suites
+pnpm cli:build              # tsc -p tsconfig.build.json -> dist/
+pnpm --filter @nextcraft/cli build:binary <tag>   # SEA binary + sha256 sidecar
+```
+
+`build:binary <tag>`: esbuild bundle (CJS, node18 target, version stamped via `NEXTCRAFT_VERSION_STAMP` define — `--version` reports the tag it was built as) → `node --experimental-sea-config` → postject injection into a copy of the system node binary → `dist/nextcraft-linux-x64` + `dist/nextcraft-linux-x64.sha256`. The binary runs without node on PATH (runtime embedded, ~117 MB).
+
+## Release pipeline
+
+Every ship from v0.3.2 onward runs `scripts/release-assets.sh <tag>` after tag+merge:
+
+1. Builds the binary stamped with the tag
+2. Resolves `GITEA_TOKEN` from `.env*` files ONLY (`.ciagent/.env.secrets` first) — never from shell env
+3. Attaches `nextcraft-linux-x64` + `nextcraft-linux-x64.sha256` to the Gitea release (bounded retry, best-effort — never blocks the ship)
+
+`scripts/install.sh` (POSIX sh, dash-safe): platform gate → Gitea latest-release API resolve → exact-name asset match → sha256 verify BEFORE install (mismatch = hard stop) → `~/.local/bin` install → PATH hint. Any failure degrades to printed source-bootstrap instructions.
+
+## Secrets policy
+
+The CLI never generates, writes, or echoes secrets. `bootstrap` copies `.env.example` → `.env` only when absent and warns on missing optional keys (mock providers keep the stack runnable keyless). Real keys live only in gitignored `.ciagent/.env.secrets`, exported by `apps/ai-service/scripts/dev.sh`.
+
+## Troubleshooting
+
+| Symptom | Cause / fix |
+|---------|-------------|
+| `pnpm not found` in doctor | `corepack enable pnpm` (installs to ~/.local/bin — ensure PATH includes it) |
+| doctor passes but verify fails on venv | re-run `nextcraft bootstrap` (venv/pip resolution is idempotent) |
+| `port 8420 busy` in verify | stop the process on :8420 (`kill $(lsof -t -i:8420)`) or set `AI_PORT` |
+| install.sh says "no binary assets yet" | release predates the binary pipeline (pre-v0.3.2); use source bootstrap |
+| Binary silent after rename | fixed since v0.3.2 (SEA argv detection); re-download the latest release |
+| Checksum mismatch on install | do NOT run the download; delete it and retry — report if it persists |
