Bugbot on #599: path.resolve treated /assets/hero.css as filesystem-absolute. Both the working directory and the artifact's directory are tried; unreadable candidates skip.
AI-assisted (Claude Code).
Greptile's third P1 on the same seam: a stylesheet linked from the artifact but outside the bounded walk's root, depth, or file limit was still invisible. The hrefs the artifact itself declares are resolved against its directory and joined to the corpus, which closes every variant.
AI-assisted (Claude Code).
Greptile's follow-up P1 on #599: with --artifact set, only that HTML file was read, so a plate referenced exclusively from a linked stylesheet still read as unused. The bounded source walk now runs either way.

Greptile P1 on #599: unreferencedPlates read a plate referenced only from assets/hero.css as unused and the hero gate refused a valid build. The extension filter already keeps binaries out of the walk.

Paul's decision on the tenth sweep's design question: hard vetoes (missing region, contradicted plate or text, SVG illustration, clipped plate, invented ink) stay unconditional; at overall >= HERO_MIN the numeric readings (ink colour, letter-spacing, line pitch, strip heights, box positions) print as advisories with the pass and belong to the polish pass. Every sweep-10 sample closes its hero under this condition, which settles 07 without another paid round.
Ninth-sweep defects: codeDrawn / container / bleed now persist into spec.json with WARN lines (an overridden refusal used to vanish from the record); font-match probes os.tmpdir() and points TMPDIR at .impeccable/tmp when the sandbox /tmp is unwritable (every ninth-sweep rank silently fell back to the catalog).

A reference, not the page: --r-<id>-x/y/w/h in % of the comp (plus cap height, font-size, family, weight where measured) to bind to any markup, and hero-reference.html with every region at its box and every plate placed with object-fit: contain, as a check on positions. Attacks the most common execution failure of weaker builders (badly positioned, overflowing, pushed below the fold) without dictating structure to strong ones; overlapping boxes are overlapping boxes and the gate reads pixels regardless.

From the final review batch: 'bad asset crop (crops are never allowed)' twice, 'letter spacing way too wide'. A crop resampled to the region scores 99.8% structure against the raw region; a produced plate scores 30-60.

A session's own note said its hero sat at 67 because the 10x10 grid boxes straddled two elements each, and it was right: every downstream measurement (cap height, line count, structure) inherited the slop. Text and control regions now snap to the dominant connected ink inside the span (page-ground threshold, dilated cells, masses touching the span's sides lose to inside masses), keep the span on the record for coverage, and can opt out with snap: false.

From the second review batch: the best build of the fifth sweep passed the hero at 87% with the cover arch cut flat on the left (object-fit: cover on a box narrower than the shape), and legends, badges, and extra controls one or two cells wide slipped under the invented-ink floor. comp-spec measures the artwork's contiguous contact with each box edge against the page ground; the spec gate refuses such a box unless bleed is set. Human pass line landed at comp-diff 72-73; HERO_MIN stays 0.72.

From the first human review of sweep-3 builds (pins on 12 samples): fonts at the wrong size, weight, colour, or place; nav bars too tall; kickers and dividers the comp does not have; a footer strip pushed off the frame that read as drift on ground colour alone; a drawing filed as chrome with no note to catch it.
- lib/hero-checks.mjs: textRegionCheck (cap height, line count, ink density, ink colour, first-line offset vs the comp crop, measured fresh), chromeStripCheck (first rule row), inventedInk (build energy over a calm comp cell and neighbourhood). Wired into gateHero as reasons; invented ink vetoes at 4% of cells.
- comp-diff verdictFor: detailRaw < 0.15 is missing whatever the palette.
- comp-spec: every region carries a note.
- font-fingerprint: the tall-line filter takes its median over lines with real mass, so two display lines above a small line are not 'tall'.

A session named seven regions for a page with three plates, a table, a note, callouts and a spine, so the hero gate could name nothing and the score sat at 70. A code region is one element; a column is a container of several.
AI-assisted (Claude Code).
font-match / catalog index
- Index schema 2 adds a third render, 48c (48px cap, ALL CAPS text). Caps headline crops have no x-height band and ranked against mixed-case renders as barcode faces; they now route to the caps render.
- Non-text families (barcodes, redacted, flow, dingbats, effect faces) are excluded from candidates.
- The distance adds a gross width and weight gap (log ratio of advance and ink density) so a face 50% wider or 35% lighter cannot rank first on run-length detail alone; the index stores those readings.
- Multi-line all-caps crops vote on x-height across lines: one line's crossbars no longer give the crop a spurious x band.
- With no browser, --rank records the catalog's nearest face (source catalog, size estimated) so the spec gate can close; the NEXT line and new-work.md say not to install a browser or hand-write a choice.
- font-match stamps the choice it writes; the spec gate refuses a chosen face it did not write (sessions typed Arial Narrow into spec.json to pass).
- IMPECCABLE_NODE_MODULES lets a harness lend a playwright.
comp-spec
- A region note that describes painted material (diagram, drawing, photo, texture...) under a code kind is refused at the spec unless codeDrawn is set: the exploded carburetor filed as chrome is a plate about to be redrawn in SVG.
build-phase
- The control ink-box veto applies only when the comp's ink is a discrete element and the build's box is too; a full-width bar told one session six times that 1376x87 was 1382x102 with no edit able to move it.

The first paid confirmation run hit a TypeError in the ink-box check
(report regions carry normalized w/h at the top level, not under box);
runGate now catches a throwing gate and returns a one-line refusal with
an explicit force path so the run is not lost to a tool bug.

font-match.mjs fingerprints a text region's lettering in the comp (cap
height, glyph advance per cap = width class, ink fraction = weight class,
tracking), renders candidate faces at that cap height in a headless
browser (yours plus a shortlist for the width class), and ranks them by
distance with a proof sheet; the spec gate refuses to close until the lead
text region is measured and ranked. generate-image --plate keys ink-on-
ground plates to alpha (chroma) so the drawing sits on the page's own
ground; the plates gate scores keyed plates composited over the region's
ground. comp-diff reports each region's ink box; the hero gate names a
control whose box height or width differs from the comp. The hero
instruction copies the comp's words verbatim; rewording is a stated
decision after the hero passes.
Driven by a human review of the r3 side-by-sides: face width and weight,
plate ground, control row height, and content substitution.

Round-1 simulated builds passed the hero at 1536 and shipped a page whose
first viewport collapsed to one column at 1440 (comp-diff 50% on the
final capture, 82% on the hero). The responsive phase now requires
desktop.png and mobile.png and diffs desktop.png against the comp at 65%
with no region missing.

From a forensics pass over twelve runs and two adversarial passes over
the metrics:
- comp-diff: detail is signed and penalizes invented energy; regions with
structure under 0.3 (or painted regions under 0.45 / added detail over
0.4) are contradicted whatever the mean says; palette ramp tightened;
region crops inherit the whole-image best translation so a shifted page
is not eight contradicted regions.
- hero gate: fails on any contradicted plate/image/text region (chrome and
controls keep the one-third allowance), on a capture that is not the
comp's frame, on a palette that is not the comp's, and on an organic
clip-path drawn inside a raster region's box.
- plates gate: scored against the comp crop with overlapping text/chrome
painted out (comp-spec plateReference; generate-image uses it too), with
a structure floor and an added-detail veto; the real plate passes, noise,
mirrors, mosaics, and other regions do not.
- comp-spec refuses a regions file that leaves comp ink unnamed.
- The direction-choice ping is folded into build-phase.mjs start
--direction --kind; the roll writes .impeccable/build/pending.json and
context.mjs / detect.mjs report COMP_ROUND_OPEN until the hero gate
passes. A code-led config makes start print the contract step and stop.

concept-seed's choice ping now prints the next mandatory step from the
recorded build path (comp-led: build-phase.mjs start --direction <key>),
because every run that skipped the comp round did so right after that
ping. build-phase gains a comps phase ahead of spec (three sidecar'd comps
under .impeccable/mocks/, one approved) and records the approved comp on
close. The hero gate lists the worst region crops first with the fix class
per verdict, and refuses a third value-only attempt on the same stuck
region. Hero instruction is plates first, then the semantic layer. The
finish reviewer treats a comp-led build with no closed comps phase as a
material finding.

The first live run produced a faithful carburetor plate, then drew the
region in SVG and left the plate on disk. Before diffing, the hero gate
now walks the artifact (or a bounded source tree) for every plate's file
name or a data URI named for it.

The first live run forced past the plates gate with 'single-file HTML
delivery requires embedded CSS/SVG'. That is not a reason the comp's
authority moves for; the script now refuses a --force whose reason does
not quote the user, and new-work.md says a single-file deliverable inlines
the plate as a data URI. Texture plates are judged on palette and grain,
not size or structure, since they tile.

Dependency-free PNG codec, perceptual metrics (structure / color / detail /
bands), side-by-side + heatmap + per-region crops, a measured spec from the
approved comp (grid overlay, sampled palette, plate list), and a phase state
machine whose spec / plates / hero gates run the diff instead of asking the
model to remember the image.
