* Add FrameBorder padding to SVG renderer matching HTML fragment nesting offset
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* Fix diagram height formula: use maxReturnY+47 to match HTML frame height
Return statements have height=0 in the positioning engine but render as 16px
elements in HTML CSS. Previous formula double-counted the return debt by both
adjusting occurrence heights AND adding totalReturnDebt to the height formula.
New formula: max(totalHeight+28, maxOccBottom+13, maxReturnY+47, maxOtherY+13)
- Returns use +47 (= viewHeight overhead) giving ~60px bottom space, matching HTML
- Other content uses +13 (= viewHeight_overhead - headerLineY = 47 - 34)
Results: return case 67.9%->72.0%, simple-messages 80.9%->91.3%,
self-call 82.6%->91.1%, creation 78.3%->86.9%, smoke 30.1%->50.0%.
Also fix svg-parity test selector (svg -> #svg-output > svg) to avoid strict
mode violation when nested SVG elements are present in the output.

* Fix return Y drift by propagating assignment return +5px debt
When a sync block has an assignment return (e.g. ret = B.method { ... }),
the occurrence grows +5px to bridge the 11→16px gap between positioning
engine and HTML rendering. This +5px was not propagated as debt to
subsequent statements, causing growing Y drift (-4/-5/-6px).
Fix: track assignment returns in computeReturnDebt and add +5 to debt
when closing such blocks.
Canonical results: 91.8% avg (+3.3% from 88.5%)
- return: 62.6% → 75.5% (+12.9%)
- repro-return-after-creation: 71.6% → 81.5% (+10.0%)
- creation-rtl: 70.6% → 78.6% (+8.0%)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Skip +5 assignment return compensation for non-block sync calls
Non-block sync calls (e.g. ret = B.method without braces) already have
correct occurrence height from the positioning engine. The +5px
compensation was only needed for block syncs where the assignment return
sits at the occurrence bottom.
return case: GeoScore B[1] height Δ=4→1, PixelMatch 75.5%→75.6%
Canonical average: 91.8% (held)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Fix assignment return Y: compute after +5 occurrence compensation
The assignment return arrow Y was computed before the +5px occurrence
height compensation, placing it 4px too high. Moving the returnArrowY
calculation after the compensation aligns it with HTML's layout.
return case: GeoScore ret0_assign_rtl.y Δ=-4→+1, PixelMatch 75.6%→76.6%
Canonical average: 91.9% (+0.1%)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Fix occurrence height +1px for return-containing and non-block assignment blocks
Two height corrections applied after returnArrowY (so they grow the
occurrence without shifting the assignment return arrow):
1. innerDebt blocks: +1px for CSS border not in positioning engine
2. Non-block syncs with assignment: +1px for coord.height shortfall
return case: GeoScore 70%→76% (occurrence heights now match), PixelMatch 76.6%→77.0%
Canonical average: 91.9% (held)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Fix return arrow X endpoints: stroke edge correction and LIFELINE_WIDTH refinement
Two fixes for return arrow X positions:
1. LTR return fromX: +1px for occurrence stroke edge (fill→visual edge)
2. LTR return toX: skip LIFELINE_WIDTH correction when target has no
occurrence (annotation returns go directly to lifeline center)
return: GeoScore 76%→82%, PixelMatch 77.0%→79.3%
repro-return-after-creation: PixelMatch 81.5%→90.3% (+8.8%)
Canonical average: 91.9%→92.5% (+0.6%)
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Fix assignment return Y: sit at occBottom-2 matching HTML border layout
HTML places assignment returns at occBottom - 2 (inside the border).
The SVG was placing them at occBottom - 1. Subtract 1 from returnArrowY.
return: GeoScore 82%→86%, PixelMatch 79.3%→82.1%
creation-rtl: PixelMatch 78.6%→81.0%
Canonical: 92.5%→92.9%
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Fix return arrow X endpoints: +1 center pixel and remove LTR LIFELINE_WIDTH double-subtraction
Assignment return retFromX was 1px short of occurrence edge because
OCCURRENCE_BAR_SIDE_WIDTH*2 (14) != OCCURRENCE_WIDTH (15) — the center
lifeline pixel was missing. Add +1 to both LTR and RTL branches.
Keyword return toX for LTR with toLayers>0 subtracted LIFELINE_WIDTH,
but the +1 stroke correction on fromX already accounts for the Anchor2
edgeOffset LIFELINE_WIDTH subtraction. Removing it fixes the double-count.
GeoScore: return 86%→92% (+6%), creation-rtl 76%→82% (+6%)
PixelMatch: return 82.1%→84.7%, creation-rtl 78.6%→81.6%,
repro-return-after-creation 81.5%→90.3%. Canonical avg 91.8%→93.0%.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Fix non-block assignment sync +1px CSS height debt for subsequent statements
HTML's CSS container for non-block sync with assignment (e.g., `ret = B.method`)
is 50px but coord.height=49. The 1px gap shifts subsequent statements down in
HTML but not in the positioning engine. Track this separately from return debt
(nbAssignShift) so it shifts Y positions without inflating parent occurrence height.
GeoScore: return 92%→96% (occ B[2].y and ret2_return_ltr.y fixed)
PixelMatch: return 84.7%→89.9%. Canonical avg 93.0%→93.3%.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Fix creation return X endpoints: use occurrence edges directly, not LIFELINE_WIDTH offsets
Creation returns connect to occurrence edges differently than keyword returns.
The sender side uses the near occurrence edge (left for RTL, right+1 for LTR).
The created side uses its own occurrence edge (right+1 for RTL, left for LTR).
LIFELINE_WIDTH corrections were incorrect for both sides.
GeoScore: creation-rtl 82%→91% (+9%)
PixelMatch: creation-rtl 81.6%→82.9%. Canonical avg 93.3%→93.4%.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Fix assignment return Y: compute after all height corrections for consistent 2px gap
The returnArrowY was computed before innerDebt post-correction (+1), using
occHeight-1. For blocks with innerDebt, the post-correction made the gap 2px
(correct). For blocks without innerDebt (like creation-rtl's a1), the gap was
only 1px (off by 1). Fix: move returnArrowY after ALL height corrections and
use occHeight-2 for a consistent 2px gap from the final occurrence bottom.
GeoScore: creation-rtl 91%→95% (+4%). return held at 96%.

* Fix assignment return sender X: +LIFELINE_WIDTH for bare lifeline RTL targets
Assignment returns to bare lifelines (no occurrences) in RTL direction were
missing the LIFELINE_WIDTH correction that keyword returns already had. This
shifts the arrow tip 1px right to match HTML Anchor2's edge offset computation.
Only applies to senderOccurrenceDepth===0 RTL — occupied senders already have
correct D4-adjusted positions.
GeoScore: unchanged (84.5%). PixelMatch improvement expected on demo1-smoke.

* Fix assignment return leftX for LTR messages with bare sender lifeline
When the original message is LTR and the sender has no active occurrence
(depth 0), the assignment return endpoint was placed at the bare center
position. HTML's Anchor2 places it at position + LIFELINE_WIDTH + 1 (the
right edge of the lifeline + stroke correction). Added this offset to match.
creation-rtl: GeoScore 95%→100%, PixelMatch 86.1%→87.0%
return: PixelMatch 89.8%→89.9%
Canonical avg held at 93.6%

* Fix occurrence height +1px for return-only blocks
The CSS border +1px correction was applied unconditionally to all blocks
with inner return debt. But return-only blocks (no non-return children)
don't have this extra pixel in HTML. Guard the +1 with the existing
mixed-content flag so it only applies to blocks with mixed content.
Also add return-only-two to canonical fixture list with baseline 94%.
return-only-two: GeoScore 94%→100%
Canonical avg held at 93.6%

* Fix PixelMatch clipping when SVG is taller than HTML
Two fixes to the Chrome extension pixel diff:
1. background.js: Math.ceil on CDP screenshot clip dimensions so subpixel
borders aren't clipped (246px SVG was losing bottom row → 245px capture)
2. content.js: Math.max for comparison dimensions instead of Math.min, with
white-padded canvases for the shorter side. Ensures content beyond the
smaller image is properly counted as HTML-only or SVG-only pixels.

* Fix PixelMatch to detect height differences between HTML and SVG
background.js: Math.ceil on CDP clip dimensions so the SVG screenshot
captures its full natural height (246px instead of being clipped to 245).
content.js: Math.max for comparison dimensions with white-padded canvases
so the shorter image's missing rows appear as background, making the
taller image's bottom border visible as SVG-only or HTML-only pixels.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Add frameHeight to GeoScore and PixelMatch height detection
GeoScore: added frameHeight field to fixtures, recorded from HTML .frame
element height. Scorer compares geometry.height against fixture.frameHeight.
All 19 cases show ~47px systematic delta (SVG missing bottom participant row).
PixelMatch: Math.max for comparison dimensions + Math.ceil on CDP clip so
both renderers are captured and compared at their full natural size.
Baselines lowered to reflect frame height as a new scored property.

* Fix return GeoScore to 100% and scorer message corrections
- Fix 1px frame height delta: track maxReturnBottom per-return with
returnOffset-aware trailing constant (62-offset) instead of flat +47
- Fix assignment return leftX +2px: add center pixel + stroke correction
to senderX for LTR messages with occupied sender
- Fix return Y -1px: add +1 non-propagating debt (via nbAssignShift) when
first return in sync block has adjust>0, compensating for missing 15→16
offset transition
- Fix scorer message Y: subtract 0.5 from SVG message Y before comparison
to account for intentional sub-pixel crisp-line offset
- Fix scorer message X: add +1 to SVG message X (lifeline center vs HTML
center+1 measurement difference)
GeoScore: 86.6% → 92.9% avg, 15/19 cases at 100%
PixelMatch: 93.6% → 94.2% avg, return case +10.5%

* Fix GeoScore scorer for message and self-call comparison
- Filter self-call messages from fixture message comparison (|toX-fromX| ≤ 50)
- Extract self-calls from fixture messages[] when selfCalls[] is empty
- Apply -32 Y offset for extracted self-calls (label height + arrow center)
- Add +1 X correction for message and self-call lifeline center vs HTML center+1
- Subtract 0.5 from SVG message Y for sub-pixel crisp-line offset
- Fix scorer test fixture to use non-self-call message coordinates
GeoScore: 92.9% → 98.4% avg, 17/19 cases at 100%

- Remove ±0.5px rounding tolerance from scorer — exact comparison only
- Add toX correction for creation messages (geometry stores center, arrow
renders to participant edge)
- creation-rtl: 97% → 100% (previous mismatch was rounding artifact)

* Fix return debt over-counting and recalibrate assignment compensation
- Skip debt for returns where positioning engine allocates height (coord.height > 0)
- Propagate occInnerDebt instead of directDebt to prevent cascading inflation
- Use coord.height > 0 for returnOffset instead of mixed-at-depth flag
- Recalibrate assignment return compensation from +5 to +4 (engine now adds +12)
- GeoScore: repro-occ-mixed-2ret 84%→100%, return-only-two 84%→100%, return 78%→90%
