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.
