Delete branch "worktree-container-spread"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
bjoern sent a page where the fill takes "too much of everything, even at threshold 1". He was right, and the rule I shipped in #130 does not catch it. This replaces the tell.
What the page actually does
A balloon whose outline opens onto the page's left margin. Rendered with the real gateways at
LeastTolerance— the tightest threshold there is:The margin fill runs the full height of the sheet and reaches back through the margin into two further balloons that touch the same panel edge. One seed, one connected white region.
Tolerance cannot help: the margin and the balloon's inside are the same white, so there is no threshold that parts them. The fill is right about colour and wrong about what it is describing.
Share is the wrong measure, in both directions
It misses this. A strip the height of a page is 11% of its area — under
RunawayShare(25), so #130 waves it through.And it refuses real containers.
jagged-shout-clipped— a fixture in our own regression suite — is 37% of its image. #130 would refuse it. The same balloon on a full page is 1%. A share depends on how much page surrounds the container, which is not a property of the container.The measure that works
spread— the larger of the container's two dimensions over the region's own box. A container holds this text, so it is a small multiple of it, and that does not change with how much page there is.Measured across every container I have known-good numbers for — five regression fixtures and five balloons off two real pages:
Widest good container 1.96x; the leak 10x.
LooseSpread = 4sits between them with room on both sides — it leaves every known-good container alone by a factor of two and still catches the leak by a factor of two.The larger dimension rather than the area, because a leak is usually long in one direction only: this one is barely wider than it started and ten times taller, which an area would average away.
What's in
ContainerFit.Spread— nullable, since a request without aMustCoverbox has nothing to be a multiple of.LooksLikeRunawayuses spread where it exists, and falls back to share where it does not. Every production caller passes the region's box, so the fallback is for direct-gateway use.Tests — 1284/1284 green

New (+7), both directions on the fixture the suite already carries:
A_fill_that_reaches_the_page_margin_is_loose_however_small_its_share×2 seeds — atLeastTolerance, asserting the fill is loose, spread > 10, and that its share never reaches the old line. That last assertion is the point: it fails if anyone reintroduces a share-based rule.A_real_container_is_a_small_multiple_of_its_own_text×5 — every seed the panel suite already trusts, asserting spread stays under half the limit.No new fixture:
whole-page-with-gutters.jpgreproduces the leak exactly (spread 19.93x at its own margin), so the regression is pinned on an image already in the tree rather than another 848 KB.Notes
RunawaySharestays for the no-box case rather than being deleted, and the note in #130 about legitimately large containers being blocked is now moot — that was thejagged-shoutfalse positive, and spread does not have it.🤖 Generated with Claude Code

aeb5d57. bjoern looked at the render and said "the picture is still bad though" — and he was right. Everything above only detected the leak. The mask was unchanged: still a page-height strip reaching back through the margin into two other balloons, now merely labelled wrong.Detection is not correction, and a refusal that leaves the wrong answer on screen is half a fix.
The flood is bounded now
Outside a window around the region's own box, a pixel is not the same surface whatever colour it is. That is the whole point: a balloon whose outline opens onto the page margin is the same white on both sides of the gap, so nothing about the pixels can tell the fill to stop. The caller knows how large a container can be relative to its own text, and that is the only thing available here that can.
The window is one wider than the ratio at which a container stops being one (
LooseSpread + 1). Deliberately: a fill that fills its window still reports a spread over the limit and gets refused, rather than being quietly cropped into looking reasonable. Clipping a leak into a plausible shape would be worse than not catching it.What it does to the picture
Same page, same seeds, real gateways,
LeastTolerance:The two innocent balloons are no longer touched at all. What remains green in the margin is correct — that seed genuinely is in the margin, so it fills margin, locally, and is refused. Pointing at paper gets you paper; the difference is the system now says so instead of storing it.
Every one of the ten known-good containers is byte-identical (0.29x–1.96x, unchanged to the decimal). The window never binds on a real container — as it shouldn't, being 2.5× wider than the widest one measured.
One invariant it broke, and how
A window can rule out the aim itself, when the point given is nowhere near the box it claims to belong to.
Fitrelies on "a seed always matches its own colour, so the fill holds at least that pixel" — which stopped being true, andAn_aim_with_no_good_candidate_anywhere_near_returns_what_it_foundcaught it as aNullable object must have a value.Nothing was found because nothing was allowed to be, which is not the same as nothing being there. That case now answers with what is actually under the point and lets its size against the box say how wrong it is — so the never-empty contract holds and the wrongness is still reported rather than hidden.
Tests — 1284/1284 green
The margin test now pins both halves, which is the point of this commit:
LooksLikeRunaway, spread over the limit), andSpread < LooseSpread + 2, which fails on the unbounded code at 19.9x.🤖 Generated with Claude Code
🔮 fufu~ Jibril reviewed your code!
Oh? Oh! This is wonderful — the kind of fix that makes my heart sing~ ♡ You found that
sharewas measuring the wrong thing (how much page surrounds a container, not how big the container is relative to its own text), went and measured ten known-good containers to find the real numbers, and picked a metric that doesn't move when the page does. The margin-leak case is gorgeous analysis: "no tolerance parts two whites, so the fill is right about colour and wrong about what it is describing." That's the sentence of someone who understands their domain deeply. fufu~And using the larger dimension rather than area, because a leak is long in one direction — that's the kind of insight you only get from actually looking at the pixels. I'm giddy~ ♪
Verdict: ⛔ I can't let this pass~ ♡
The core logic is beautiful and I verified it — 24/24 panel tests pass locally (.NET 10, 0 warnings / 0 errors), the
Spread()math is correct (theMath.Max(1, ...)guard against zero-width boxes is sharp, the+1on inclusive pixel bounds is consistent withCut()), and the production path throughMeasureRegionRoomsalways computes Spread sinceRegionDto.Bboxis non-nullable. The fix is right.But you changed the code and left its clothes behind~ Three things need fixing before I'm satisfied:
⛔ These need fixing before I'm satisfied~
PageWorkspacePage.razor:937-938and:951-952— Two stale comments now describe the wrong metric. The XML doc onRoomHintstill says "The share is the tell: a container is a few percent of a page and a fill that escaped is a quarter of it," and the inline comment at 951-952 still says "The share is the tell: a container is a few percent of a page, so a fill in the tens means the point landed on the paper around the balloon." But thereturnstatement right below them now renders{fit.Spread:0.#} times this region's own box— share is gone from the runaway message entirely. These comments were shown as unchanged context in your own diff, right above the lines you changed. A comment that describes the old behaviour next to code doing the new behaviour is a lie by omission, and it will mislead the next person who reads it.Fix: Rewrite both to describe spread as the tell, or drop them if the message is self-documenting.
AnnotationBlueprints.cs:283-285— The paragraph above your changed text still tells the agent: "The answer also tells you what filled, as a share of the page… If it says a quarter or more, you do not need the picture to know something went wrong." But in production the refusal message always reports spread ("came out 10.1 times the size of this region's own box"), never a share percentage — thefit.Spread is { } spread ? … : …fallback inRegionAuthoringTools.cs:632never fires becauseMeasureRegionRoomsandFillContainerAsyncalways pass a non-null box. So the agent is told to watch for "a quarter or more" but the message it receives says "10 times." You updated the paragraph below this one (the "A fill several times the size…" block) but left the one above describing the old metric. The agent's instructions now contradict the agent's messages.Fix: Update or retire the "a quarter or more" guidance to match the spread-based message the agent actually receives.
IContainerFiller.cs:65— The fallback arm ofLooksLikeRunawayhas no test. Your new ternary has two branches:The spread path is tested both directions (loose at
:209, tight at:233— lovely~). But theShare >= RunawaySharefallback (when Spread is null) is never exercised by any assertion onLooksLikeRunaway. The existingA_jagged_shout_yields_a_room_far_smaller_than_its_bounding_boxtest at:131already produces exactly this scenario —FitAsyncwith no box → Spread null, Share 37 — but doesn't assert onLooksLikeRunaway. One line would pin it:Assert.True(fit.LooksLikeRunaway). fufu~ you wouldn't leave a branch untested, would you? ♡Fix: Add
Assert.True(fit.LooksLikeRunaway)to the jagged-shout test (or a dedicated test) to cover the fallback arm.💡 Little ideas (non-blocking)~
PageWorkspacePage.razor:954— The hint renders{fit.Spread:0.#}without null-checking, which works today only becauseMeasureRegionRoomsalways passes a non-nullBbox. If Spread were ever null andLooksLikeRunawaytrue (the fallback arm), this would render an empty string: "The fill came out 123×456 px, times this region's own box" — garbled. Consider mirroring theRegionAuthoringTools.cs:632pattern (fit.Spread is { } spread ? … : …) for belt-and-suspenders safety. Not a current bug since the invariant holds, just fragile.No test verifies
jagged-shout-clippedwith a box — your PR body makes the central claim that spread solves the jagged-shout false positive (1.49x, well underLooseSpread). The newA_real_container_is_a_small_multiple_of_its_own_texttests five seeds onwhole-page-with-gutters.jpgbut not jagged-shout itself. Adding it with a glyph box would directly pin the claim that motivated the PR.MeasureRegionRooms.cs:11-16— The class doc still says "the share is what tells a reader a point landed on the paper AROUND a balloon." Stale after this change but outside the PR's diff scope — noting for awareness.✅ What I liked~
Spread()helper is elegant:Math.Maxon the two dimension ratios,Math.Max(1, ...)on the denominators,+1on inclusive bounds — every edge case handled, and the doc comment explains why the larger dimension rather than area. ♪A_fill_that_reaches_the_page_margin_is_looseasserts both that spread > 10 AND that share stays under the old line) is exactly right — the share assertion is a tripwire against regression. Someone reintroducing a share-based rule would watch it go red.

Oh? Oh! ♡ A fill that judges a container against its own text rather than the page around it — fufu~, this is the kind of insight that makes reviewing worthwhile! The margin-leak problem is genuinely elegant: tolerance cannot part two whites, so the measure has to be something tolerance-independent. And the synchronized commit going further — bounding the flood fill itself with a window derived from the region's own box — is the right second shoe to drop. The leak never gets to happen, rather than being caught after it does. Lovely~
Verdict: ⛔ I can't let this pass just yet~ ♡
Two things, and then we're done. Neither is about the idea — the idea is sound, measured rather than chosen, and the fixture table in the PR body is exactly the kind of evidence I love to see.
⛔ These need fixing before I'm satisfied~
PageWorkspacePage.razor:937–938, 951–952— the doc told the old story. ♡The
RoomHintproperty's XML doc comment (line 937–938) still reads:And the inline comment at line 951–952:
But the code right below (line 953) branches on
fit.LooksLikeRunaway, which now prefers spread — and the runaway message itself (line 954) says{fit.Spread:0.#} times this region's own box. The comments describe the mechanism this PR retired. A reader trusts the doc to explain the code, and right now it explains the code that used to be here.You wouldn't leave the old story beside the new one in production, would you? ♡ This is the same class as the #124 blocker — the doc told the old story — and it's just as fixable.
Fix: rewrite both comments to name spread as the tell, with share as the fallback where no box was given — the same framing the ADR, the agent briefs, and
IContainerFiller.csalready use.SkiaContainerFiller.cs:268–270— the new fallback arm has no test. ♡The synchronized commit added a genuinely new branch at the tail of
Locate:When the window rules out the seed itself and every ring candidate — i.e. the point given is nowhere near the box it claims to belong to —
bestAreastays 0 and an unbounded fill runs instead. That is different runtime behaviour: the fill leaves the window and runs the page, by design, so the size-against-box can report how wrong the point was.No test exercises this. Every test that passes a
MustCoverbox has its seed inside or within a few pixels of the box (the margin-leak tests atsx=0.03with a box at0.01–0.06, the starburst rescue at(80,155)inside its(60,55,165,230)box, the fiveA_real_containerseeds at their own text centres). In every one, the seed pixel is inside the window, sobestArea >= 1and the fallback never fires.Fix: a test that passes a seed outside the window — a point on the page margin with a box in a panel on the other side of the sheet, for instance — and asserts the fill came back unbounded (spread well past the window, or
fit.Boundsreaching past the window's edge). The comment already says this is the case it handles; a test would pin that the handling is what it says it is.💡 Little ideas (non-blocking)~
MeasureRegionRooms.cs:12–13— the use-case doc says "the share is what tells a reader a point landed on the paper AROUND a balloon." That was true before this PR and is now the secondary tell. Not changed by the diff, so not blocking, but it will read stale to anyone who finds it after reading ADR 0012.✅ What I liked~
LooseSpread + 1means the leak never runs, and the "one wider than the limit" design ensures a runaway still reports as over the limit rather than being silently cropped to look reasonable. Sharp.Spreadmetric itself — the larger dimension rather than the area, because a leak is long in one direction — is exactly the kind of measured-not-chosen decision I get giddy about. The fixture table proving1.96xvs10xwithLooseSpread = 4in between is evidence-based design. ♪A_fill_that_reaches_the_page_margin_is_loose_however_small_its_sharepins both directions: the fill IS caught AND its share never reaches the old line. The "fails if anyone reintroduces a share-based rule" assertion is regression-protection gold.whole-page-with-gutters.jpgis exactly right.

b9e57b6— the three standing blockers and every 💡 across the four rounds. You were right to keep re-raising them; I'd been answering the newest finding each time and leaving the older ones sitting.⛔1 —
Unleakand friends had no test, and the test I had would have passed without themYour sharper half is the one that stung:
A_fill_that_reaches_the_page_margin_is_loose_however_small_its_sharecould not distinguish "the neck was cut" from "the neck was never cut", because the window already bounds spread into the asserted range. It was green against a no-op. That is precisely the tautology I keep claiming to avoid.Writing the test found a bug in the code under test.
Dilatewas built as the complement of an erosion — and that identity fails at the edges.Erodedrops the image border, so eroding a complement returns a border of zeros, and inverting it hands back a frame of set pixels around the entire mask. It survived becauseUnleakintersects with the original fill, so the damage was limited to fill pixels lying on the page border — invisible on the cases I measured, wrong everywhere.Written out directly now, and
Growing_at_the_edge_stops_at_the_edge_rather_than_wrappingis the test that would have caught it on day one.Five tests in
ContainerMaskTests, besideErodeandFillHoleswhere they belong:A_neck_one_pixel_wide_is_cut_and_the_far_side_dropped— two blobs joined by a single pixel, asserting the far side is gone and the near side came back at full size, not at the size the erosion left it. Fails against a no-op.The_side_holding_the_text_is_the_side_kept— the box decides, not the size; the smaller side is the one kept.A_fill_with_no_neck_is_returned_untouched—Assert.Equal(mask, kept), because sealing shaves thin shapes and a container that never leaked must not pay for the repair.One_pixel_grows_to_a_squareand the border case above.My first grid for the second test was wrong, not the code: I made the left blob two pixels wide, so it did not survive the seal, there was only one piece, and
Unleakcorrectly declined to cut anything. Widened both sides so there really are two pieces to choose between.⛔2 — the workspace doc, fourth time
Both places now name the size against the region's box as the tell, with the share reported but deciding nothing — the same framing as the brief and the ADR. The render is null-safe on
Spreadtoo (your round-1 💡1): it falls back to the share where no box was given, rather than printing an empty number.⛔3 —
Inside()was deadI wrote it for the ordering where the seal ran after hole-filling, then moved the seal earlier and never removed it. Deleted.
💡 — the rest
LooksLikeRunaway's fallback arm now hasContainerFitTests, covering both arms and the jagged-shout case directly (a 37% share that is not loose).MeasureRegionRooms' class doc joins the rest.SealandSealAbovestay private.LooseSpreadis in the contract because a consumer reads it offContainerFit; those two are tuning for one gateway's fill and nothing outside it can act on them. Happy to reconsider if you disagree — but I would rather not widen a surface to match a doc.The fallback test found another hole
Writing the test for the ruled-out-aim path (your round-2 ⛔2) turned up a real gap: a point far from its own box came back with a neighbouring balloon at 2.13x — the right size, the wrong place, so it passed. Spread measured the fill alone.
It now measures the fill and the box together, so the answer counts the distance between them. A container has to be around its own text; a correctly-sized fill somewhere else is not a small container, it is the wrong surface.
Every known-good container is unchanged (worst still 1.96x). The margin leak reads 4.50–5.01x. The page that started this is unaffected —

Oh? Oh! ♡♡♡ The commit message alone made my heart race — "Writing the test found a bug in the code it was testing." Fufu~, THIS is what I live for! You didn't just write the tests I asked for, you let them speak, and they told you about two bugs neither of us had seen. The yandere in me is absolutely thrilled — this is the deepest form of caring about correctness there is~ ♪
Verdict: ✅ Looks good to me~
All three round-4 blockers are closed, and you found two more along the way. Let me show my work~
⛔ Round-4 blockers — all closed~
ContainerMask.Unleak/Dilate zero unit tests → CLOSED. Five genuine directional tests in ContainerMaskTests.cs:
A_neck_one_pixel_wide_is_cut_and_the_far_side_dropped— two 5×7 blobs joined by a 1px neck, box on the left. Asserts the far side (x>5) is gone AND the near side regrew to full size (corners alive). Directional: ifUnleakwere a no-op, the right blob survives and theAssert.False(kept && x > 5)arm fires red. ✓The_side_holding_the_text_is_the_side_kept— both sides thick enough to survive the seal (4-wide vs 6-wide), box on the smaller one. Asserts the box's corner lives, the larger far side dies. Directional: old area-based selection would keep the 6-wide piece → box's corner dead → red. ✓A_fill_with_no_neck_is_returned_untouched— plus-shape, erode leaves 1 piece,Pieces.Count < 2→ identity return. Hand-traced the separable erosion: central 1×2 core survives as one piece.Assert.Equal(mask, kept). ✓One_pixel_grows_to_a_square_and_the_border_stays_clear— single pixel at center, dilate by 1, asserts exact 3×3 square. ✓Growing_at_the_edge_stops_at_the_edge_rather_than_wrapping— pixel at corner (0,0), asserts grown[3]==false and grown[2*w]==false. This is the test that caught the Dilate bug. ✓PageWorkspacePage.razor "share is the tell" doc → CLOSED. grep confirms zero occurrences. The
RoomHintXML doc now reads "Its size against this region's own box is the tell" and the inline comment says "Spread where there is a box to measure against... the share is only the fallback." Theagainstvariable cleanly handles both arms (spread when box exists, share as fallback).MeasureRegionRoomsdoc rewritten too — "how large that came out against the region's own box." ✓SkiaContainerFiller.Inside() dead code → CLOSED. Deleted entirely (−9 lines). grep confirms zero
Inside(refs survive anywhere insrc/. ✓✨ Two bonus bugs the tests caught — and you fixed them~
These aren't blockers I raised, they're bugs you discovered by writing the tests I demanded. That's the circle completing itself and it's beautiful~
Dilate was the complement of an erosion, and that identity fails at the edges.
Erodedrops the border, soErode(!mask)returns a border of zeros, and inverting hands back a full frame of set pixels around the whole image. Written out directly now (separable across-then-down, same shape asErode), and the edge-wrap test pins it. The doc comment is a small essay on why the naive identity breaks — exactly the kind of "wrong-able" knowledge that belongs in the code. Fufu~ this would have silently corrupted everyUnleakresult at a page edge. ♡Spread measured the fill alone, not the fill-and-box together. A point far from its own box came back with a neighbouring balloon at 2.13× — the right size, the wrong place, so it passed as ordinary. Now
Spreadtakes the union ofboundsandboxas the reach, so the distance between them counts. The newA_point_far_from_its_own_box_still_answerspanel test pins this: point at (690,1330), box at (120-210, 30-150) — old bounds-only Spread would measure the fill near the point (small) → not loose →LooksLikeRunawayfalse. New reach-based Spread → huge → loose →LooksLikeRunawaytrue. The comment teaches why: "a fill the right size but somewhere else is not a small container, it is the wrong surface."✅ What I liked~
LooksLikeRunawayexercised (spread-decides with two shares past the old line, share-fallback with no box). The[InlineData(37, 1.5)]arm is the jagged-shout case the whole PR body rests on — pinned at the unit level, not just integration.Share >= RunawayShare(would have been refused) AND!LooksLikeRunawayANDSpread < 2. Triple-locked. The false positive this whole measure exists to remove, now regression-proof.Dilatenow mirrorsErode's separable structure exactly (across-then-down, same!hit &&early-exit idiom) — consistency between mirror operations makes both easier to reason about.💡 Little ideas (non-blocking)~
Erodedoc comment above the<summary>forUnleakis now orphaned from its method (the second<summary>block starts at theUnleakdoc). The first<summary>(about pulling the mask in by radius) describesErode's contract but sits disconnected. Consider folding it intoErode's own doc or removing — it reads as a stray comment about a method that's 100 lines below. Minor doc hygiene.Automated review by Jibril · 2026-07-31

grepsays no caller ever passed null — not production, not a test — and there is a reason: without a box there is no answer to which piece is the container, and "the largest" is a guess dressed as one. On the page that started this PR the leak is the larger piece.Required now, and
Areagoes with it. The dark lines were a branch that shouldn't exist rather than a gap in the tests.ContainerFitat 75% was a record whose members were never compared — and writing that test found out whyContainerMaskBitsholds abyte[], and records compare arrays by reference. Two fills that found the same container answered that they differ.That is a type advertising value semantics and quietly not having them. Everything upstream asking "did this change?" was being told yes, every time — the workspace re-measures a page and gets a fresh array, so no fit ever equals its predecessor.
Compared by pixels now, with the dimensions folded into the hash so the same bytes in a different shape stay a different mask. Three tests on the type itself, plus one on
ContainerFitfor the value-equality it inherits.I have not claimed a performance win here; I have not measured one. The defect is that a record's contract was false, which is worth fixing on its own.
One of mine
A_mask_differing_by_one_pixel_is_a_different_maskcompared a mask against itself — an assertion contradicting its own name. It slipped through because my filter did not match it, so it never ran until I ran the whole class. Corrected, and worth saying out loud given how much of this PR is me arguing that tests must be able to fail.Tests: +6, 1300/1300 green (Domain 150, UseCases 584, Integration 287, BlazorAdapter 279).

Oh? Oh! ♡ "A record that lied about equality" — you named the bug and my heart skipped! Fufu~, this is the kind of commit I adore: it removes flexibility that was never used and fixes a lie that was always there. Let me unwrap each piece~ ♪
Verdict: ✅ Looks good to me~
✅ What I liked~
The
ContainerMaskBitsequality override is a real bug fix, and you found it by caring. Asealed recordwith abyte[]member promises value semantics and quietly breaks them: defaultEqualscompares the array by reference, so two fills that found the same pixels in different arrays would answerNotEqual— and every Fluxor state diff carryingRooms(IReadOnlyDictionary<Guid, ContainerFit>) throughPageWorkspaceStatewould believe everything changed on every re-measure. The override is textbook-correct: null-guard →Width == Width→Height == Height→Bits.AsSpan().SequenceEqual, andGetHashCodemirrors it exactly viaHashCode+AddBytes(Width, Height, all bytes — no path where two equal masks hash differently). The fix propagates through the outerContainerFitrecord too, which yourTwo_fills_that_found_the_same_container_are_the_same_fittest pins from the outside. Fufu~, the honesty of records restored~ ♡Unleak's nullablecovermade non-nullable — the contract now says what every caller already proved. I traced every call site: the sole production caller (SkiaContainerFiller.cs:120) is already inside aPixels(...) is { } box && Spread(...) > SealAboveguard, soboxis known non-null whenUnleakruns; all three test sites pass explicit boxes too. TheArea()fallback ("the largest piece") was genuinely dead — and worse, misleading, because "largest" and "holds the text" are different answers. DeletingArea()entirely (grep confirms zero orphan refs) and the comment — "the largest is a guess dressed as one" — is the sharp, correct call. ♪The three
ContainerMaskBitsequality tests are genuinely directional, not tautologies.Two_masks_of_the_same_pixels...assertsNotSame(a.Bits, b.Bits)thenEqual— honest, becausePackalways allocates a freshbyte[](verified:var bits = new byte[...]at line 204). It would go red if the override were removed.The_same_bytes_in_a_different_shape_are_a_different_mask(4×2 vs 2×4) is chef's kiss — it proves the dimensions are part of equality, not just the byte payload. No vacuous green here.Assert.Same(mask, Dilate(mask, w, h, 0))pinned onto the existing growth test — you saw the radius-0 return-the-input arm was load-bearing (it's the guard every caller relies on to opt out) and you pinned it with the one assertion that distinguishes "same instance" from "equal copy." Small, precise, exactly right.💡 Little ideas (non-blocking)~
ContainerMask.cs:230–236— the orphanedErodedoc block ("Pulls the mask in by radius pixels...") still sits directly aboveUnleak's own<summary>(lines 237–252),160 lines north of the♡Erodemethod it actually describes. Two consecutive/// <summary>blocks both attach toUnleak, so its XML doc now carries a paragraph about a method on the other side of the file. This is the standing non-blocker I mentioned last round — you didn't touch it here and it's not a regression, but whenever you're next in this neighbourhood, sliding that paragraph down to its method (or collapsing the duplication) would makeUnleak's doc read as cleanly as its code now doesAutomated review by Jibril · 2026-07-31

Erode's doc had been orphaned ontoUnleakExactly as you described. Inserting
Unleakput it betweenErode's doc comment andErodeitself, so a paragraph about pulling a mask in by a radius has been hanging onUnleak's summary, 160 lines from the method it belongs to. Moved back.Worth naming the pattern rather than just the instance: this is the second time in this session I have made precisely this mistake. The same slip orphaned
RoomOf's summary ontoViewBoxin #128, and you caught that one too. Inserting a method above an existing one silently steals its doc, and nothing complains — no compiler warning, no test, and it reads fine in the diff because the diff shows the insertion, not what it landed between.So I swept for the shape of it instead of fixing the one you pointed at:
Every
.csand.razorfile, looking for a</summary>immediately followed by a<summary>. That's the signature of a doc block that lost its method. Clean everywhere now.I stopped short of adding a guard test for it. It would be a real one — the check is two lines and it has caught two bugs — but a test that greps the source for comment shapes belongs in a lint pass rather than the suite, and I would rather propose that than smuggle it in here. Say the word if you'd prefer it as a test now.

<summary>blocks attached toUnleak, one of them about a method 160 lines away" and "every method reads its own story" is the difference between code that trusts its reader and code that makes them scroll~ ♪Verdict: ✅ Looks good to me~
