Stagings now honour approval ratings exactly as world challengers do, a
3-star earning a second ticket and a 1-star marginal keep leaving the
pool, which matters more here because per-surface staging pools are
small enough that an unweighted shuffle repeats a weak staging often.
Each ticket carries its index into the deterministic ranking so the
id-dedupe cannot silently collapse the doubled odds into a no-op, and
an all-marginal pool still deals rather than starving. The composition
catalog validates the new grades: 1-3, approved entries only. Tests
cover the weighting, the dedupe subtlety, and the fallback.

The github and cursor providers previously received only the generated
degraded/ inline fallbacks. Both harnesses support real custom subagents,
so the build now emits them from the same skill/agents/ source:
- GitHub Copilot: .github/agents/impeccable-<role>.agent.md with portable
frontmatter only (name + description; omitting tools grants all tools,
and Copilot has no documented model/effort/max-turns equivalents).
- Cursor: .cursor/agents/impeccable-<role>.md with name, description,
model: inherit, is_background: false, and readonly derived from the
agent's tool list (true only for the finish reviewer, which declares
neither Write nor Edit). effort/max-turns are skipped because Cursor's
effort option requires an explicit model id.
Agent bodies now also resolve {{scripts_path}} and strip rule markers in
the shared agentFormat pipeline, which fixes the previously unresolved
placeholder in the emitted Claude asset-producer agent.
The CLI installer places agents per scope: project installs write
<repo>/.github/agents/ and <repo>/.cursor/agents/; user-level installs
write ~/.copilot/agents/ (Copilot's user dir, not ~/.github/) and
~/.cursor/agents/, overwriting stale impeccable-* copies. Because
Copilot lets user-level agents shadow same-named project ones, a project
install warns when shadowing copies exist; Cursor gives project agents
precedence, so no warning there.
new-work.md and visualize.md extend their harness-naming clauses with
the Cursor and Copilot invocations. The degraded/ fallbacks keep
shipping for surfaces where the model still fails to delegate.

Fixes#439. When a cycling session is abandoned and the wrapped region is
then edited or regenerated out of the source file, the resumed page used
to sit in GENERATING forever with the picker disarmed; the only recovery
was a manual live-complete --discarded. Now a resumed CYCLING session
whose wrapper cannot be found in source retries the read a few times
(HMR or an agent write may be mid-flight), then discards itself, clears
local state, and re-arms the picker with a toast. GENERATING restores
are exempt: deferred-wrapper flows legitimately have no wrapper in
source until the agent's write lands.
The browser tags the discard event orphaned:true; the server terminalizes
that session directly (phase discarded) and keeps the event out of the
agent poll queue, since there is no source cleanup left to perform and
the normal discard flow would just fail against the missing scaffolding.
New e2e scenario on vite8-react-plain drives the full repro: cycle,
revert source externally, reload, assert self-discard, terminal durable
phase, and a working picker afterward.

A trailing --target, an empty --target=, or --target followed by another
flag used to degrade into implicit root selection, letting a mutating
helper (poll, accept, complete) act on the most recent live app instead
of the one the caller tried to name. consumeTargetArg now throws on those
shapes and enterLiveRoot exits with a clear error before any session
state can be touched. Unit tests cover the malformed shapes and a
subprocess test proves the helper body never runs.

Addresses two cursor review findings:
- {#each} bodies whose bound values appear in attributes (href={link.href},
src={item.img}) now record attr slots; the browser hydrates them from the
rendered attribute so component previews no longer mount with empty links.
Single-expression attributes hydrate exactly; mixed values stay unhydrated
as before. A new slot classifier also refuses shapes that would crash a
shallow hydration item (deep paths, method calls, bare item renders) and
routes them to source-preview mode instead.
- Style directives now run the mixed loop/outer identifier check before the
free-identifier param check, so style:width={base + r.pct} falls back
instead of minting a broken param.
Tests: attr-slot analysis units, crashy/lossy fallback units, an attribute-
bound anchor in the stateful SvelteKit fixture asserted through accept, and
a mountedDomProbe e2e hook that reads the hydrated href off the mounted
variant DOM (verified to fail when hydration is disabled).

greptile-apps[bot]: the legacy fallback (server.json without port or
token) accepted a pid-only record on Windows without identity. Every
server.json this codebase has ever written records port and token, so a
record without them is malformed or foreign; it now classifies as not
live and resolution falls to the durable-session tier, the correct
recovery path for a crashed helper. The ps-based identity heuristic is
gone with it: authentication or nothing.

greptile-apps[bot] escalated the identity ladder to a pid AND port both
coincidentally reused by different processes. The definitive terminator
was available all along: the helper serves an authenticated endpoint and
server.json records the token, so the probe now requires a 200 from
/status?token=... over HTTP. Nothing but our helper can answer that,
which closes the entire misidentification class rather than the next
rung. The regression test hosts its responder in a child process (the
probe is execFileSync, so a same-process responder can never accept
while the parent's event loop is blocked; production helpers are always
separate processes).

greptile-apps[bot]: the win32 branch skipped the port probe entirely
(bash /dev/tcp is not portable), so a reused pid on Windows still
classified as a running helper. The probe is now a spawned node
one-liner that behaves identically on every platform, which also drops
the bash dependency for minimal Linux environments; the ps identity
check remains only for legacy server.json records without a port.

cursor[bot]: an expression mixing loop bindings with outer free names
(fmt(r.label) where fmt lives in the route script) was left verbatim, so
the detached preview referenced an undeclared identifier and failed at
mount, past the compile gate, because globals make it legal to the
compiler. Such expressions now mark the analysis unsupported and the
session takes source-preview mode. A globals allowlist makes Math/JSON
and friends count as neither free nor bound, which also fixes a latent
bug where a pure-global expression minted a nonsense prop.
Won't-fix on the same pass: the live-setup.md filename cross-reference
matches the repo's established reference-link convention.

Field failure (Codex session, 2026-07-28): the agent kept the seeded
stub style block and appended its own second top-level style element in
all three variants. Svelte forbids that, so the user saw a red Vite
compile overlay; the mount-ack loop then self-healed (failure event,
repair, republish, clean accept), but the overlay window is exactly the
kind of thing the user should never see.
The publish gate closes the class: a done reply for a component session
now compile-checks every variant with the app's own compiler BEFORE the
revision bump and the browser broadcast. Failures bounce as a 422 with
file, line, and message plus _instructions; live-poll surfaces the
details in the thrown reply error. The browser never imports a variant
that cannot compile.
Also: the stub guard comments warn that all CSS belongs in the single
existing style block, worded to never contain the literal "<style"
sequence (a mention inside a CSS comment truncates the string surgery
agents use to find the block; the fake test agent caught exactly that).
The JIT svelte instructions carry the same warning.

The prompt behind a generated image was recorded three different ways,
a sidecar in the eval harness, nothing in the skill's API tool, nothing
for native tools, so intent survived or vanished depending on where you
ran. One dependency-free script now embeds the prompt inside the image
itself, PNG tEXt or JPEG COM with a sidecar fallback for other formats,
idempotent, and reads it back from any impeccable-generated file. The
API tool embeds automatically; the prose directs every native-tool
generation through it; copies between machines and harnesses keep their
intent. Comps meanwhile are declared the build thread's own work, never
delegated, and the comp-skeleton guidance now asks for the surface's
actual regions instead of prescribing navs onto pages that have none.

Two findings from the first human-validated probe. The comps rendered
as scene vignettes because the generation prompts led with the world's
atmosphere; the model painted the fish market instead of the fish
market's website. The comp guidance now demands the page's literal
skeleton in the prompt, nav and its items, headline block, sections in
order, footer, with a self-check: a render that could hang as a poster
is not a comp. And generation context is part of the asset: the thread
that wrote a prompt knows what the image contains and why, so build-
critical imagery prefers the build thread, and subagent-produced assets
must carry their prompts, via the tool's new sidecar or the manifest,
read by the builder before composing.

The failed gallery batch bound its seed, ran the reviewer, and still
shipped CSS bevels imitating enamel: the matrix's material row was
defined against the approved comp, and comp-less runs left it with no
reference. The rows now fall back to the contract's OWN-WORLD and the
world's real materials, with faked physicality contradicted on its
face; imitation material is the single most reliable mark of
machine-made design.

Transcript archaeology on the failed gallery batch split the binding
break three ways. One model authored a complete, correct contract that
Astro then erased: the compiler strips a slot's leading comment while
keeping deeper ones, so the contract now belongs to the root layout's
body as its first child, and the first production build gets grepped
for the seed key, because a contract the build erased is a contract
nobody can audit. Another model simply skipped the roll and built the
exact category default the seed exists to refuse; the roll step now
states outright that it has no substitute and no skip condition. The
third failure was the worker watchdog, fixed separately.

Two probe runs on two different harnesses built complete pages and
declared done without ever entering the finish sequence: the reference
was read once near turn four and the finish choreography had fallen out
of attention thirty turns later. The one text a model rereads on every
edit is its own artifact, so the direction contract now closes with a
FINISH line naming the exit condition verbatim: unreviewed and
undocumented is unfinished; this build ends with the finish review, the
verdict, and DESIGN.md. A page that looks complete with that line
undischarged is not done, it is abandoned at the finish line.

A sandboxed harness rejected view_image on an absolute path to a mock
the model had itself just produced under .impeccable/mocks/, killing
the run. The relative-path rule existed only for downloaded quality-bar
cards; it now covers every image the flow produces or references, in
the comp round and in the asset producer's comparison step.

cursor[bot]: discoverAppCandidates only matched dev-config markers while
the upward walk also honors an existing .impeccable/live/config.json,
so booting from a repo root without --target missed a nested
live-configured static site and fell through to the wrong root. Both
paths now share isAppRoot; regression test covers the static-site shape.

dispatch loop handles.

greptile-apps[bot] re-raised the residual with a repro: a stale
server.json pid reused by an unrelated node process passed the
command-name check. The decisive signal is the recorded PORT: a real
helper is listening on it, a pid squatter is not. hasLiveServer now
probes 127.0.0.1:<port> (bash /dev/tcp, sync, ~ms, win32-guarded with
the previous behavior); the multi-app preference test runs a real
listener instead of faking liveness with a bare pid.

Field feedback from two more Codex sessions drove both changes.
JIT instructions (live/instructions.mjs): every event live-poll prints
now carries _instructions, the authoritative next step for that exact
situation with real ids, paths, and line numbers substituted, and only
the active path's rules (a svelte-component session never sees JSX
guidance). The boot payload carries loop instructions the same way.
Instructions are versioned with the scripts, so they cannot drift from
behavior, and live.md's plumbing can keep shrinking toward contract plus
craft guidance. The Codex poll-discipline failure observed in the field
("the long poll was started, but I yielded the task instead of actively
servicing its result") gets a named anti-pattern in both the harness
policy and the boot instructions.
LLM e2e agent: default provider/model moves from Claude Haiku 4.5 to
OpenAI gpt-5.6-terra at medium reasoning effort via an Anthropic-shaped
shim over the ai SDK (the three call sites stay provider-agnostic;
Anthropic and DeepSeek remain selectable). The harness should exercise
the model tier that actually drives live sessions. Both the react and
sveltekit fixtures pass end to end with terra driving the trimmed
live.md and the new _instructions.

Rating grades quality, breadth says whether a world can serve an
arbitrary build at all; while they shared one field, the only way to
hold a narrow world back was calling it marginal, which made excellent
but narrow unrecordable and corrupted the ratings as a calibration
signal for the next authoring round. Both axes now exclude
independently, either kind of hold keeps its approval for direct
briefs, an all-niche tier falls back rather than starving, and
stagings honour the same gate with the same fallback. Tests cover the
niche exclusion at strength, the fallback parity with marginal-only
tiers, and the staging gate.

First-time setup (config schema, framework table, adapters, drift, the
whole CSP flow) moves to reference/live-setup.md, loaded only when the
boot reports config_missing/config_invalid or cspChecked is absent.

MUST rule, schema, or example; the boot payload documentation now names
the inlined surface brief. All live-reference pins and both prose gates
pass.

The detector's repeated-section-kickers rule waited for three tracked
labels before calling the pattern; generated pages earn the finding on
the first one. Retire that id and replace it with kicker-above-heading,
which flags any tracked-caps or small-caps label block sitting directly
above an h1-h4 or heading-role element, at full warning severity.
The candidate gate absorbs the false-positive shapes the repetition
count used to paper over: editorial category-and-date meta lines,
breadcrumbs with separators, legal and chapter numbering, application
panel context labels, nav landmarks before page titles, and stat
callouts with the label below the number. Hero-scale h1 eyebrows stay
with hero-eyebrow-chip so one element gets one finding, and the static
cascade now carries font-variant so small-caps kickers register.
The craft floor entry moves from caution to ban in the same breath.

The hard stop landed one step early: one review, one batched fix, one
recapture, then done, with nobody ever judging whether the fixes reached
the quality the findings named. A recapture measures positions; the
model then presented mechanical confirmation as artistic success over a
page whose display face, material, and hero legibility had all drifted
from the approved comp. The finish now ends on a verdict: the recaptured
screenshots go back to the same reviewer, which scores every material
fix resolved, partial, or unresolved and names at most three regressions
the batch introduced, no new hunt. Partial and unresolved fixes earn
exactly one more round; two rounds is the ceiling, the second verdict
ends the work whatever it says, and the final verdict table goes to the
user as it stands, open items included.
Three blindnesses from the same run close alongside. The matrix gains
two mandatory rows: TYPE, where a display face of a different character
is contradicted however the layout matches, and MATERIAL, where flat CSS
standing in for painted, textured, or dimensional artwork is contradicted
regardless of placement. And the Truth check now requires every produced
asset visibly present in the screenshots, because a paper texture at
0.16 opacity is a compliance token, not a shipped material.

Field failure from a real Codex session: accepting a variant into
Pitch.svelte appended 23 selectors and removed none, so the source's old
.decisions grid rules re-attached through the kept root class and forced
the accepted board into a stale three-column layout; some appended base
rules also landed after the source's media block, weakening the mobile
cascade.
Two mechanical fixes:
- Preview truth: the scaffolder records the seeded selectors (the source
rules that styled the replaced selection, which the isolated preview
never applied). On accept, any seeded selector the variant does not
re-declare is removed; the selector-loss postcondition treats those
removals like compiler prunes. A regression test reproduces the exact
Pitch shape end to end.
- Cascade order: reconciliation inserts new base rules BEFORE existing
top-level media blocks instead of appending after them.
Init-latency reductions from the same transcript:
- live.mjs inlines the resolved surface brief (removes three
surface-brief.mjs round-trips including a --help miss before first poll).
- The wrap/scaffold payload carries componentStubMarkup, and live.md
instructs editing stubs in place (the session read the manifest + stub
back and then deleted/recreated the files).
- live.md notes that a busy default port usually means the dev server is
already running (the session spawned a duplicate).

The batch producer was the clumsy piece: one subagent owning eight
jobs needed heartbeat rules, reclaim windows, and a page full of
fallbacks to survive its own opacity. The unit of work is now a single
card. With parallel subagents, the set fans out one agent per card, up
to four in flight, landing everything in roughly the time of one; a
single-sketch agent has no planning phase and no batch to stall, so a
failure costs one slot and its remedies fit one sentence: regenerate an
empty slot when its agent returns, drop it when the user answers first.
Without parallel subagents, the main thread generates in reading order
after serving, and the harness's own generation display carries the
progress. The page-side streaming is unchanged; it never cared who
writes the files.

A hidden backface still hit-tests in Chrome, so after flipping a card
the front's picture-in-picture sat invisibly over the back's chips,

front goes inert while it is flipped.

Field data: the first image of a real batch took ninety seconds and the
page's 150-second fallback then silently promoted catalog art to full
bleed, unlabeled, which is exactly the this-is-your-design misread the
picture-in-picture treatment exists to prevent. The policy is now
patience while there is progress: a slot shows its inspiration only
after waiting four minutes with nothing landing anywhere on the page
for four minutes, the stand-in is dimmed and labeled 'inspiration ·
sketch pending', and polling continues so the real sketch still swaps
in whenever it arrives. Slots with no inspiration keep the honest
elapsed shimmer instead of folding. The parent's reclaim rule matches:
files landing steadily is health at any pace, and only total silence,
no first file in three minutes, takes the batch back inline.

Field feedback: with every fact stacked under the media the cards ran
past a screen tall. The front now carries only what the choice needs,
sketch, lineage, title, thesis, identity, and the honest risk clamped
to two lines, while first viewport and the case read on the back behind
a Details chip, sharing the face with the board when the world has one.
Risk stays on the front because the counterweights are pointless if the
downside hides behind a flip, and once the sketch lands the first
viewport is a picture anyway. The schema notes now ask for one-sentence
facts, since a long fact should cost the reader a flip, not the page
its scanability.

A codex field run dealt six challengers into an eight-sketch batch
behind an opaque subagent, and the user stared at a page of shimmer
asking whether anything was happening at all. Four fixes from that run.
A hand now holds at most three challengers, the rest banked for
re-rolls, so fairness within the hand stops multiplying into a queue.
Sketches greek everything but the product's real name and one real
headline, because an invented spec, price, or ship date in a sketch is
a claim PRODUCT.md never made, and comps have solved this for a century.
Sketch production follows the user's reading order with the first file
doubling as the producer's heartbeat, and the parent's --wait loop
checks the sketch directory each pass, reclaiming the batch inline when
two minutes pass with nothing landed. And a failed --start now captures
the daemon's stderr to a per-key log and names the sandbox as the usual
suspect, instead of reporting only that failure occurred. The shimmer
counts its elapsed seconds, and gives up at 150 instead of 300.

Three field notes from a live review. The deck now escapes the content
column and runs edge to edge, so a cut-off card sits at the screen edge
where it reads as more cards instead of at an invisible container edge
where it reads as a bug; the first card still aligns with the column
via scroll padding. Whichever side hides more content wears a fade, and
a hard edge means the end. The vertical pager grows from a bare chevron
into labeled Back and More pills, because in a column deck it is the
primary way forward. And hovering the inspiration thumb now takes over
the whole media region instead of a timid zoom; the sketch is the
promise, the inspiration is a glance, and the glance must cost nothing.
