P1: templates said 'python X' — the in-ns PATH resolves only python3 (no
bare python on the box); the declared harness would have failed with rc 127
in every real tracked sandbox. Templates + UI fallbacks now use python3
(caught by the new MH-4d real-server E2E, exactly as the verifier
predicted).
P2: the exec policy now unions the template's DECLARED harness argv[0]
into the allowed set (a future non-python harness template must not reject
its own Run command); 'python' removed from the generic set (deliberately
— in-ns resolves python3 only; pip absent: no network in the namespace).
MH-4c: web pins — test() derives from variant.test_command (whitespace
split, no shlex import); TaskVariant environment + test_command REQUIRED
(a-11); the build-surface header shows the kind (· build/design/
simulation) instead of the hardcoded '· build'.
MH-4d: test_design_kind_e2e_real_server — real uvicorn + real namespace:
design variant → starter files via the file API → in-ns harness exec
(python3 validate_flow.py; validator reports ISSUES on the starter flow —
by design, the learner edits it) → out-of-policy 422 → contiguous seq
chain stored (0..N, ordered, unique). G-17 satisfied: concrete
assertions, no hope-shaped must-haves.

typecheck/web 12/cli 45), but MH-4c has ZERO web tests, MH-4d's design E2E
does not exist (the test file's docstring claims it does), and the declared
harness commands ('python ...', 'pytest') do not resolve inside the real
sandbox fabric (rc 127, only python3 exists on the in-ns PATH)
Four layers over the execute diff (milestone/v0.5..HEAD, 12 files):
- STRUCTURAL: MH-4a PASS. Diff scope exactly as declared — backend.py and
workdir.py UNTOUCHED (D-044 holds: registry at the template/variant
layer; manager change is the minimal +5-line _task_ids side-table,
stamped in create manager.py:178, popped in destroy manager.py:253;
reaper/destroy_all route through destroy so the table cannot leak).
Dual-schema sync verified by schema dump: VariantResponse requires
[learner_id, task_id, template_id, competency_id, seed, params,
statement, starter_files, environment, test_command, created_at] — TS
TaskVariant mirrors all 11 field-for-field, environment typed
'build'|'design'|'simulation', both new fields REQUIRED on both sides
(a-11 ✓). G-15 validator probes: 'python "a b.py"' REJECT,
'sh -c "echo hi"' REJECT, ' ' REJECT; but 'python a;b', 'python $(x)',
'python a.py > out', 'python a*.py' ACCEPT — the docstring's
'no quotes, no shell metachars' claim is half-false (P2). NBSP probe:
'python a\xa0b.py' ACCEPTS and diverges — Python shlex keeps one token,
JS /\s+/ splits it in two, violating the validator's stated purpose
(P2; no current template affected). Exec path shlex.quotes every token
(unshare_backend.py:102,443) so accepted metachars are inert at exec.
- BEHAVIORAL: PASS. pytest 473 passed in 110s (expected 473); ruff clean;
pnpm typecheck 8/8 forced-fresh; web tsx --test 12 pass (expected 12);
cli 45 pass (expected 45). v0.3 template/generator/store suites green
(tests/variants/ 40 passed); validate_competency_binding accepts the
new c011/c001 bindings.
- SECURITY: policy probes. Design: 'rm -rf /' → 422 naming the set ✓;
'sh -c'/'bash -c' → 422 ✓; ' pytest' → 422 ✓; cyrillic-о 'pythоn' →
422 ✓ (exact token). ['python','-c','import os; os.system(...)'] →
ALLOWED — argv[0]-token contract per PLAN G-15 wording ('sh -c
passthrough' is what's blocked; namespace+rlimits remain the boundary,
unchanged v0.3). task_id=None → policy skipped = v0.3 pure-shell
semantics (confirmed intended). _task_ids lifecycle clean on all
destroy paths. Two contract notes: (P2) the policy ignores the
template-declared harness argv[0] entirely — the plan said
{template-declared} ∪ generic, the implementation is a fixed generic
set {ls,cat,pwd,echo,python,python3,pytest,pip}; today's templates
coincide (python/pytest) but a future non-python harness template would
reject its OWN harness, and design sandboxes accept pytest the plan
would exclude. (P1) migration: SQLModel create_all does NOT ALTER
existing tables — a pre-v0.5 variant_record row read under v0.5 raises
OperationalError (proven against a simulated stale DB); the repo-local
dev DB (apps/ai-service/ai_service/data/nextcraft.db, .env-pinned
AI_DB_PATH, 11 rows, pre-v0.5 schema) would 500 on every cached-variant
read after upgrade; store.py:109 comment 'defaults keep pre-v0.5 rows
build' is false — old rows cannot be read at all. Tests never see it
(tmp DBs); the deleted ~/.nextcraft DB was the wrong DB — the live one
is in-repo.
- QUALITY: starter files proven by direct execution — validate_flow.py
reports ISSUES rc=1 on the scaffold, VALID rc=0 after edits;
simulate.py reproducible, metrics shape correct, its pytest suite 2/2.
BUT in a REAL tracked sandbox the declared commands fail: PATH inside
the namespace = /usr/local/sbin:...:/bin, 'python' → rc 127 'not found',
'pytest' → rc 127; only python3 resolves (probed via live UnshareBackend
exec). The design/sim Run/Test buttons would fail on the real fabric for
template-authored reasons; the v0.3 E2E masked this because it asserts
exec HTTP 200, never returncode. The missing MH-4d E2E is exactly the
test that would have caught it (P1). MH-4c: zero web tests touch
test_command/use-sandbox-session/build-surface (grep across
apps/web/tests); 'Run button label/command per kind' — command is
variant-driven, label is hardcoded 'Run'/'Test' and the header still
says '· build' for every kind; the environment field is consumed by NO
UI component (P1 must-have gap). MH-4d: TestDigestKindAgnostic pins the
digest over a SYNTHETIC design trace (fine, kind-agnostic pinned:
TraceDigest has no environment field) but the real-server design E2E —
design variant → sandbox → starter files → Run harness in-ns →
telemetry → digest with stored-seqs-contiguous-0..N — does not exist
anywhere, and test_environments.py:10-12 docstring claims it does
(docstring lie, the class prior verifies flag as P0). MH-4b: design
rejects/accepts + build-unchanged tested; the 'simulation accepts its
declared harness' case has no test (proven allowed by probe; P3 gap).
Simulation Run button runs test_command (pytest) not the declared
harness (python simulate.py) — harness_command/run_command is stamped on
the template, doc'd ('The Run button's command: kind harness when
declared'), and then never leaves the template layer: dead field, the
exact class this phase was meant to close (P2; plan is self-ambiguous —
surface #3 says Run=harness, Task 4-3-01 says Run/Test=test_command).
Hermeticity: the identity-test db_path pins are correct, but the NEW
test file's own Settings (test_environments.py:40,131) omit db_path →
create_app opens the .env-pinned repo-local dev DB for its
trace/grade/defense stores (P2; the conftest hermeticity comment says
tests must never do this).
Must-haves: MH-4a PASS; MH-4b PASS (sim-harness case untested, policy not
template-informed); MH-4c FAIL (no web tests, label not per-kind);
MH-4d FAIL (E2E absent; docstring claims otherwise).

requirements:
covered: [REQ-5-005]
partial: [REQ-5-006]
lessons:
- An E2E that asserts HTTP 200 but never returncode proves the transport,
not the harness — 'python' and 'pytest' do not exist on the in-ns PATH
(only python3); every template-authored command must be executed in a
real namespace before it ships, or the Run button fails for authored
reasons the API honestly reports as 200+rc127.
- SQLModel create_all is create-only: additive model columns on an
existing SQLite table silently do not migrate, and a comment claiming
'defaults keep pre-v0.5 rows' is false when the rows cannot be read —
probe schema evolution against a seeded old-schema DB, not a fresh one.
- A test-file docstring that names must-haves is not evidence the tests
exist — grep the assertions (uvicorn/contiguous/spool) before crediting
the MH; MH-4d was credited in the module docstring by a file containing
only a synthetic-trace digest pin.
- argv[0]-only policy is the declared G-15 contract, but 'template-declared
harness ∪ generic' and 'fixed generic set' are different policies: the
implementation chose the latter without saying so — policy tables must
be probed against the plan's set definition, not just the 422 path.
---/ci---
D1 (P1, security): malformed DOB previously reached derive_age_band on the
verify path → ValueError 500 whose traceback echoed the raw DOB into
uvicorn.error logs (A-305 violated) — and the poisoned pending record made
every resubmit 409: a REMOTE, PERMANENT lockout of any learner id (self-
asserted learner_id means anyone could poison anyone). Now: pydantic
boundary validation (422 before anything touches the value) + an app-level
RequestValidationError handler that redacts PII field inputs and strips
non-serializable ctx (keeps every other route's 422 shape JSON-safe).
Pinned: no 500, no echo in response OR logs, no poisoned record, resubmit
still 200.
D2 (P1, security): require_verified_age fail-OPENED on non-canonical bands
(None/'banana'/'under-16' passed the 18+ marketplace gate). Now fail-CLOSED:
only canonical bands pass; min_age>16 requires exactly '18+'. Pinned with
raw-SQL planted rows (the future-vendor/direct-write path).
D3 (P2): store now refuses non-canonical bands on insert AND mark_verified
(transitions validate like inserts). D4 (P3): latest_for_learner tiebreaks
by rowid (deterministic last-inserted-wins); dead school_gate/marketplace_
gate factories removed (require_verified_adult alias per D-043);
SubmitResponse mock comes from record provenance, not hardcoded. D5 (P3):
store docstring honesty (@validates claim corrected; read paths re-label tz
like the family). D6 (P3): .env.example documents AI_IDENTITY_*; the build
surface renders the verify-CTA LINK on identity-gate 403s (G-10 → hook
state.verifyCta), not just the message.

P0-1: recorder.start(1000) fires ondataavailable PER CHUNK; the handler
posted each 1s slice as a complete answer and killed the stream — every
voice answer truncated to ~1s (or split into two turns). Chunks now
buffer into chunksRef until onstop posts ONE complete blob; stop is the
single completion signal; the G-12 auto-stop bound is now reachable.
P0-2: jsonFetch forced Content-Type: application/json over FormData bytes
— every real audio answer died as 422 (provide {text} or audio). FormData
now sets its own multipart boundary; pinned by a header-assertion test.
P1-1: voice_tts_format as a pydantic Literal raised ValidationError at
Settings construction, BEFORE main.py's G-11 fallback could see it — a
typo'd env crashed the unattended boot (exit 1, verified). Now str +

broken at the wire (two P0s the missing component tests would have caught);
G-16 enum crashes boot instead of G-11 fallback
Four layers over the execute diff (milestone/v0.5..HEAD, 13 files):
- STRUCTURAL: MH-2b/2c PASS (factory branches + boot survival + loud log +
a-15 descriptor flow at defense.py:143; codec-strip/413-before-call/422/
media_type pins green; v0.4 rejection test inverted). MH-2a PARTIAL: STT
multipart + TTS JSON/byte pins solid, key-leak pins green, but the TIMEOUT
pin named by the MH does not exist (413/400/429 only). MH-2d PARTIAL:
FormData + 413-client pins green; badge-reflects-mode and auto-stop pins
absent (no component test harness) — exactly where the P0s hide.
- BEHAVIORAL: all gates green — 436 python, 6 web, 45 cli, typecheck,
ruff/lint, static export builds (out/defend/* emitted). Gates cannot see
the browser-path P0s below because the web tests stub fetch and never
render the component.
- SECURITY: key-leak audit CLEAN — every exception path sanitized (413/400/
429/500/connect-error/non-JSON/echo-portal probes; key only [REDACTED] or
absent; multipart content never echoed; main.py fallback log carries only
the provider name + static error). ReadTimeout is an httpx.HTTPError
subclass → sanitized on both STT and TTS (verified empirically). TTS hang
bounded by pool read=300s (acceptable, noted). Advisory a-9 NOT
implemented: defense.py:184 reads the full upload before the 413 check —
advisory-compliance gap, noted.
- QUALITY: dual-schema sync exact (TS VoiceMode == Python Literal). voice/
boundary AST test green with the new file. D-2 class staleness: four
'v0.4' claims now false (base.py:34, defense.py:93, browser.py:3-6,
mock.py:78); MOCK_DESCRIPTOR is dead on the wire AND its stale hint is
pinned by a test (test_voice_layer.py:130 asserts 'v0.4' in the hint).
DEFECTS:
P0-1 defense-session.tsx:162-169 — start(1000) timeslice + submit-every-
chunk handler: the first ~1s chunk is posted as the whole answer and
stream.getTracks().stop() kills the recording at ~1s; the finalization
chunk (when non-empty) posts a SECOND learner turn. Every voice answer is
truncated to the first second (or split into two turns); the G-12 180s
bound/auto-stop is unreachable. Proven from MediaRecorder semantics: the
pre-diff handler assumed a single final blob (recorder.start() no-slice).
P0-2 engine-client.ts:244-257 via jsonFetch:81 — answerDefenseAudio sends
FormData through a wrapper that forces 'Content-Type: application/json';
real fetch round-trip through the shipped code shows the server receives
multipart bytes with a JSON content-type → FastAPI 422 'provide {text} or
audio'. Every audio answer from the real browser fails; the web test
asserted the FormData body but never the request headers.
P1-1 G-16: plan says unknown voice_tts_format falls back with a loud log
(consistent with G-11); implementation is a pydantic Literal →
AI_VOICE_TTS_FORMAT=flac crashes at Settings construction, uvicorn exits
1 (verified). Violates the D-039 unattended-boot doctrine this plan cites.
P1-2 MH-2a timeout pin missing (behavior verified correct manually).
P1-3 MH-2d badge + auto-stop pins missing.
P2: a-9 advisory skipped silently; stale v0.4 docstrings (4 sites);
MOCK_DESCRIPTOR dead + test pins its stale hint; defense-session.tsx:283
hardcodes '180s' duplicating MAX_RECORD_SECONDS; openai_audio.py:85
non-dict 200 body raises a raw (keyless) AttributeError.
REQ-5-001 covered (provider byte-contract, selection, env-only keys,
mock/browser unchanged — G-16 boot deviation noted). REQ-5-002 partial:
server side proven (mock-pinned), the web client's real upload path is
broken end-to-end by P0-1/P0-2.
---ci---
phase: 2
milestone: v0.5
status: verify
requirements:
covered: [REQ-5-001]
partial: [REQ-5-002]
lessons:
- A fetch wrapper that forces Content-Type silently breaks FormData
bodies; a stubbed-fetch test that never inspects headers passes while
every real request fails. Multipart paths need header pins (or must
bypass the JSON wrapper).
- recorder.start(timeslice) changes ondataavailable from one-final-blob
to per-chunk semantics; every pre-existing submit-on-dataavailable
handler becomes a truncation bug. The two MH-2d pins that were skipped
(badge, auto-stop) were exactly the tests that would have caught P0-1.
- pydantic Literal enums reject at construction — they can never deliver
a G-11 'fall back with loud log'; that contract needs a str field plus
a fallback validator, as the plan actually specified.
- Advisory items (a-9 Content-Length fast path) dropped silently read as
done in summaries; advisories need an explicit not-done note.

D-1 (P0/P1): _flush_locked no longer compacts the spool to [last_sent] —
that discarded sent-but-unacked lines before any ack could arrive, exactly
the in-flight window REQ-5-007 exists to close (a burst into a dying socket
lost lines 1..N-1). Post-fix the spool retains everything unacked;
replay_margin requeues the FULL unacked window on disconnect; trim_to_ack
(server seq_ack) is the only spool shrinker; server dedup absorbs replays.
Pinned by test_burst_into_ack_withholding_link_loses_nothing.
D-2 (P0): dropped-overflow docstring claimed 'status event + logs' — the
agent has no logging; corrected to the true surface.
D-3 (P2, latent): emit() held a non-reentrant _emit_lock across sends; a
send failure re-entered via _drop_conn -> replay_margin and hung the
emitting thread >8s in the verifier probe. Now an RLock.

window is NOT closed for the unacked-burst interleaving; plus one P0
docstring lie and one latent pre-existing deadlock on the emit path
Four layers over the execute diff (milestone/v0.5..HEAD, 6 files):
- STRUCTURAL: PASS with one docstring defect. All four MHs are implemented
as described: seq_ack emission ingest.py:361 (post-append latest_seq,
emitted on dedup too, a-6), _line_seq/trim_to_ack/_handle_server_text/
_enforce_spool_bound_locked/spool_max_lines in sandbox-agent.py
(158-169, 371, 428, 432-450, 480-504, 566-591), stop() surfaces
dropped_overflow (739-746), protocol docstring updated (ingest.py:18-20).
AST stdlib test green (sandbox-agent.py imports only stdlib — new code
adds zero imports). No other files changed (.ciagent/CHECKPOINT.json
expected). BUT _enforce_spool_bound_locked's docstring claims the
counter is surfaced in the status event "+ logs" — the agent has NO
logging at all (P0 docstring lie, same class as the P04 finding).
- BEHAVIORAL: PASS. Targeted suites 54/54 green; full suite 421/421 green
(>=421 confirmed); mid-burst test green on 3 fresh consecutive runs
(4/4 total counting execute); MH-1a ack-emission test proves
acks == [0,1,2,2] incl. dedup replay; MH-1b tests prove exact trim,
bound, honest-gap flush (first delivered frame >= dropped count);
MH-1c proven by a generated 4-cycle kill/emit/revive probe (31/31
checks: zero loss, zero spool dup, margin = unacked-only, ack
convergence).
- SECURITY: PASS. Hostile seq_ack probe: negative/non-int/float/None/
missing/non-dict/garbage/invalid-utf-8 frames all ignored, no crash
(isinstance-int + >=0 validation, sandbox-agent.py:588-591); bool True
is treated as int 1 (Python quirk, hostile-server-only, harmless — real
ingest sends ints); enormous seq trims all without crash or counter
corruption (server-trusted advisory, in-namespace agent only ever
talks to the configured ingest); trim_to_ack drops only seq<=ack
(unacked retained, probed); overflow drops only OLDEST (newest window
kept, probed). No secrets/log concerns (agent logs nothing; no new
env/secret surface; NC_* env baked at spawn).
- QUALITY: PASS with defects. Ruff clean. Lock discipline correct for the
NEW code (trim runs under _emit_lock; pending deque rebuilt, not
mutated; Spool.rewrite atomic via os.replace + fsync). PROBED DEFECT
(P1, protocol design gap): _flush_locked's compaction
(spool.rewrite([last_sent]), sandbox-agent.py:468) fires on every
drained emit — sent-but-unacked lines are DISCARDED from the spool
before any ack can arrive. Blackhole-RST probe: 6-frame burst into an
unacking link → spool holds [6] only; seqs 1..5 are lost on kill. The
P07 gap the phase set out to close ("N frames in TCP flight — frames
1..N-1 are lost") is closed ONLY for the interleavings the tests
cover (server acks before the kill); for a rapid burst into a dying
link the pre-D-045 one-line margin still applies. MH-1d's test
passes because uvicorn acks fast enough — it does not pin the
unacked-flight window. Also PROBED (P2, pre-existing, out of scope):
emit() holds _emit_lock; a send failure routes _drop_conn ->
replay_margin which re-acquires the same non-reentrant lock →
self-deadlock on the first emit after a dead-link send (probe:
hung >8s). Latent because the supervisor normally drops the conn
first. Unchanged lines; flagging for the executor, not a phase
regression.
Must-Haves: MH-1a PASS, MH-1b PASS, MH-1c PASS (probe-proven), MH-1d
PASS as tested (with the P1 caveat above). REQ-5-007 covered for the
tested interleavings; the unacked-flight window remains open — a trim
of compaction discipline (hold last_sent UNTIL acked, or retain
sent-not-acked lines) would close it.

lessons:
- A green mid-burst regression test proves the covered interleavings,
not the protocol's worst case: _flush_locked compaction can discard
sent-but-unacked lines faster than acks arrive — write probes that
withhold acks deliberately before claiming a flight window is closed.
- Agent docstrings must not claim log surfaces that do not exist; the
stdlib-only agent has no logging — grep for 'logging' before writing
"+ logs" in any agent docstring.
- generate probes for hostile-frame edges (bool-as-int quirk included)
— docstring-conformant validation still has Python quirks worth
pinning in tests.

The public site was down: HAProxy forwards nextcraft.coreci.dev to the
ai-service and only :8420 is reachable, so the domain root hit FastAPI's
404. Now one port serves both: the web app builds as a static export served
same-origin by the ai-service (AI_WEB_STATIC_DIR), with NEXT_PUBLIC_AI_
SERVICE_URL=self relative fetches. Unattended ops: `nextcraft dev -d`
(daemon), `stop`, `log [-n N|-f]` — pid/log under ~/.nextcraft/run/. Durable
state (SQLite db, sandbox workdirs) moved out of the repo to ~/.nextcraft/

The public site (nextcraft.coreci.dev) 404s because HAProxy forwards the
domain to the ai-service alone and the web app was never reachable (only
:8420 is open). This makes ONE port serve BOTH surfaces:
- Web: `output: 'export'` static build (apps/web/out) with generateStaticParams
for all 7 dynamic routes; NEXT_PUBLIC_AI_SERVICE_URL=self bakes relative
same-origin fetches (engine-base-url "" base; engine-client already
concatenates). No CORS, no mixed content, no Node web server in prod.
- API: optional AI_WEB_STATIC_DIR StaticFiles(html=True) mount AFTER all
routers (API wins; / serves index.html; unknown paths serve the export's
404.html with status 404; set-but-missing dir fails startup loudly).
Default unset — dev/tests unchanged.
- CLI: `dev -d/--detach` (daemon; ~/.nextcraft/run/<clone-hash>/dev.{pid,log},
refuses double-start, auto-wires AI_WEB_STATIC_DIR when out/ exists),
`stop` (SIGTERM→SIGKILL 5s), `log` (-n N lines, -f follow). stdlib only.
Founder directives (this hotfix):
- unattended/daemonized dev with a tail command — dev -d / log / stop
- only 8420 reachable — single-port same-origin topology
- runtime state must NOT live in the repo — db_path default moves to
~/.nextcraft/data/nextcraft.db, sandbox_dir to ~/.nextcraft/sandboxes/;
expanduser validator (AI_DB_PATH=~/... works); .env.example stops pinning
repo paths; daemon pid/log also under ~/.nextcraft.
Test hygiene: conftest settings fixture pins stores to tmp_path (was silently
using repo defaults); sandbox tests use a bind-mount-safe sandbox_dir fixture
(overlayfs /tmp breaks userns bind mounts with ENODEV — home ext4 works).

- P1 requirements: 27 v0.1 requirement rows (REQ-002..028) still said pending — contradicting the traceability matrix in the same file, PROJECT.md, and ROADMAP (v0.1 shipped as v0.1.0); all set complete
- P1 grill consistency: GRILL CUT-2 (no xterm in v0.3) never propagated to PERSONAS.md (frontend frameworks listed @xterm/xterm) and ARCHITECTURE.md build order (xterm.js build/run); PROJECT.md A-103 still claimed a WebSocket xterm terminal on a bwrap sandbox; all aligned to the shipped read-only exec-output panel (CUT-2/G-8, D-024 unshare)
- P1 architecture drift: api/ row missing the five v0.3 routers (sandboxes/telemetry/variants/defense + grade endpoint); voice/ row missing factory.py + defense_store.py; agents/ row missing examiner.py; main.py row missing engine-store lifespan wiring; ui/types rows missing the v0.3 primitives and engine type modules; data-flow section still described the v0.2 mock-agent flow as current
- P2 docstring: IngestSession still documented the pre-P7 len(get_trace) O(n²) flood-cap count that the P07 fix replaced with TraceStore.count()

phase: 7
milestone: v0.3
status: review
lessons:
- P0 CORS: allow_methods lacked PUT while the build surface writes files with PUT — every cross-origin Save failed preflight; pinned with tests/api/test_cors.py
- P0 ingest leak: queue-overflow flood path returned without the disconnect sentinel, parking the drainer forever (one leaked task-set per flooded trace); sentinel now always enqueued, real-server regression test added
- P1 perf: flood cap counted rows via len(get_trace(...)) — O(trace) per append, O(n²) per session; TraceStore.count() (COUNT(*)) added and wired
- P0 security: file routes followed exec-planted symlinks out of the workspace bind; _resolve_in_workspace refuses escapes (422), read/write now 404 on unknown sandboxes (was 500)
- P1 security: WS ingest accepted any browser Origin (CORS middleware does not cover WS); localhost dev origins + no-Origin (capture agent) allowed, others 1008
- P1 correctness: use-sandbox-session leaked a created sandbox on any mid-start failure (per-learner cap 1 → all retries 429 forever); failed starts now destroy what they created
- P2 testing: reconnect-flush test killed mid-burst (nondeterministic under load, reproduced on pre-change code); now waits for server-side observation of the pre-kill burst — the underlying one-line replay-margin/ACK gap is documented for v0.4
- maintainability: grading-store/templates/grading.ts docstrings claimed grading is variant-blind (stale pre-P4 text) — updated; ARCHITECTURE.md referenced nonexistent voice/openai_audio.py; dead if TYPE_CHECKING: pass blocks removed
---/ci---
The defend page fabricated taskId = `task-${competencyId}`, but variant
task_ids are `task-<seed[:16]>` (D-029) — so in the real browser flow the
defense ran against an empty trace (no digest grounding) and Grade My Work
always returned UNGRADABLE_EMPTY_TRACE. The E2E test masked this by passing
the real task_id directly.
Fix: DefenseSession resolves the learner's stored variant by competency
via GET /v1/variants?learner_id (new listVariants client), defends + grades
under the variant's real task_id, and shows an honest empty state when no
build session exists for the competency yet.

milestone: v0.3
status: verify
requirements:
covered: [REQ-3-008]
partial: []
lessons:
- A green E2E test can still mask a broken UI wiring when the test hand-picks
the join key the UI is supposed to derive; verify browser flows against the
ids the pages actually construct, not the engine contract alone.
