Align the initializer contract with Summary.swift.
The design specifies a public initializer without payloads. The implementation is an internal initializer that requires PayloadProviding and accepts bundleNames. Update this section so the design matches the implemented seam.

Make the browser fixture self-contained.
StubPayloadProvider returns linking URLs but never writes the payload or log files. The browser plan loads report.html, so attachment and log sources resolve to files that do not exist.

Re-enable the accessibility gate before relying on this test as a CI assertion.
GATING_IMPACTS is empty. Therefore, gating is always empty and the assertion always passes after Axe returns results. Critical and serious violations, including future regressions, only appear in logs.
Fix the documented image and frame accessibility defects, then gate critical and serious impacts. If the gate must remain disabled, do not present this test as enforcing critical and serious accessibility violations.

Nothing here has ever asserted anything about how the report looks. The three existing comparisons -- DifferentialTests, ReproducibilityTests, BaselineCaptureTests -- all compare one render to another render, and none of them knows what any of it means. A token that resolves to nothing, a dark-mode palette that fails contrast, a filter tab that stops filtering: all pass silently. That became load-bearing when #439 started redesigning the UI. #455 tokenized the stylesheet and claimed "zero visual change" with no test able to confirm it; #456 adds dark mode and asserts WCAG floors. Those are claims a browser checks mechanically and a reviewer cannot. Three layers over one synthetic ParsedResult fixture: unit tests on model logic, per-template HTML goldens, and Playwright for the facts only a browser knows. Layers 1 and 2 add no toolchain and need neither simulator nor .xcresult. The design turns on a constraint BaselineCaptureTests already documents: fixtures regenerate, so a golden keyed to one cannot be checked in. The way out is to stop feeding renders from generated fixtures -- hence the synthetic fixture, and hence the one production change, a Summary initialiser taking pre-parsed runs. Also records a defect found while writing this: TestScreenshotFlow discards its tailCount parameter and hardcodes suffix(3). Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Phase 1 builds the Swift foundation -- a StubPayloadProvider, a synthetic ParsedResult covering every rendered status, and a Summary initialiser taking pre-parsed runs. Phase 2 adds golden snapshots keyed to that fixture rather than to a generated .xcresult, which is what makes them committable at all. Phase 3 adds the browser layer. Task 1 opens RED on the tailCount defect the spec recorded. Task 12 hands the finished suite to #456 and unskips the dark-mode assertion there, which is the sequencing argument's payoff: the first claim about how this report looks that a machine, not a reviewer, checks. Three assertions in the plan are verified by deliberately breaking something and confirming the failure -- an undeclared token reference, a contrast floor, and a changed golden -- because an assertion that has never failed is one nobody should trust. Selectors are taken from HTMLTemplates.swift rather than guessed: `.selected` is the live selection class, group rows sit under `.run.active`, and the filter tabs are `<li>` elements carrying counts. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…spec The spec called PayloadProviding a three-member protocol, but it declares five: url, exportPayload, exportPayloadData, exportLogs, exportLogsData. Task 2's SyntheticResultTests fixture is what surfaced the discrepancy.
…lename assertion
Review fix round 1: the three tests repeated the same 11-line
runs→testables→groups→ParsedNode extraction chain verbatim. Extracted a
private allTestCases() helper. Also widened
testCoversHostileAttachmentFilename to require all five hostile
characters the fixture filename actually carries ("'<>&), not just two
of them, so the assertion pins what the fixture provides.
Adds an internal Summary.init(parsedRuns:payloads:renderingMode: downsizeImagesEnabled:downsizeScaleFactor:faultCollector:bundleNames:), alongside the existing public path-based initialiser, so tests can render a full report page from SyntheticResult's fixture with no .xcresult and no simulator. This is the injection point #391 made possible: ParsedRun is now the boundary between reading and rendering, so tests can construct one directly instead of reading it out of a bundle. Internal, not public, because PayloadProviding is internal; @testable import reaches it from tests while library consumers keep the resultPaths-based initialiser untouched. SummarySeamTests exercises the new seam: a full page renders (<!doctype html>, the fixture's SyntheticSuite group, the :root token layer), the complete synthetic tree produces zero faults, and two renders of the same fixture are byte-identical.
…egrading SyntheticResult.parsedRun passed logReference: nil, which sent Run.init? down the else branch: a warning to the console, and logContent = .none — no logs section at all in the rendered page. Every golden HTML file from Task 4 onward would have pinned a report missing that pane, and StubPayloadProvider.exportLogs/exportLogsData would have stayed dead code no test ever reached. Fixing this now, before any goldens exist, is the cheapest point to do it. StubPayloadProvider gains a logText constant and real exportLogs/ exportLogsData implementations that mirror exportPayload/exportPayloadData: resolve from the same exports map, touch no filesystem. SyntheticResult registers a logReference in payloads and wires it into parsedRun. SummarySeamTests.testRendersAFullPageWithoutAnXcresult now asserts the logs iframe doesn't degrade to an empty src. A new test, testInlineRenderingEmbedsTheActualLogBytes, proves the fixture's log bytes reach the rendered page for real: under .inline rendering the iframe src is a data: URI, so the exact base64 encoding of logText is a verifiable substring of the output. .linking mode (used elsewhere in this file) only yields a content-free relative file name, so it cannot by itself prove real bytes made the trip — the .inline mode assertion is required to confirm the fix's actual purpose, not just that the warning went away. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…undles Parking the entire Resources directory also removes differential-allowlist.json, the fourth Package.swift-declared resource. With zero resolvable resources SwiftPM synthesizes no Bundle.module, breaking the whole test target's build — a packaging artifact, not evidence the synthetic-fixture suites need .xcresult fixtures. Parking only the three .xcresult bundles isolates the actual claim.
Introduces the browser test layer: a pinned Playwright + axe-core devDependency set, chromium-only config with retries disabled, and two assertions over the report's computed CSS custom properties — every declared :root token resolves to a non-empty value, and no rule references a token that was never declared. Verified the second assertion actually bites: temporarily broke a var(--color-text-primary) reference in HTMLTemplates.swift to var(--color-text-nonexistent), re-dumped the fixture, and watched `no rule references an undeclared token` fail naming the bogus token. The template edit was reverted before committing.
Both CSS scanners in tokens.spec.ts filtered on `rule instanceof CSSStyleRule`, which is false for CSSMediaRule — so the @media (prefers-color-scheme: dark) :root block PR #456 added was invisible to both assertions. A stylesheet with a token declared or referenced only inside that block would pass "no rule references an undeclared token" vacuously; the name was inaccurate. Walk CSSGroupingRule.cssRules recursively (covers @media, @supports, @layer alike) in both evaluate bodies. Verified the walk now visits 2 :root rules instead of 1, and that a var() reference broken *inside* the dark block is caught post-fix but was silently missed by the pre-fix scanner against the same fixture.
Adds a two-job workflow: a macOS job dumps the synthetic render fixtures via VisualFixtureDumpTests (no simulator, no .xcresult, no prepareTestResults.sh needed — Package.swift's differential-allowlist.json resource is enough to synthesize Bundle.module), then an Ubuntu job downloads those fixtures and runs the Playwright suite against them. setup-node and download-artifact are pinned to their actual latest releases (v7.0.0 and v8.0.1) rather than the older SHAs from the initial draft; download-artifact's SHA matches the one already pinned in release.yml.
The WCAG contrast test's effectiveBackground() walk treated any element's non-transparent computed background-color as a real painted surface. The #439 icon refresh (merged to main via #459, which this branch predates) switched .preview-icon and friends to `mask-image` + `background-color: currentColor` — the standard single-colour tintable-icon technique. That background-color is clipped to the icon's silhouette by the mask; it is never a rectangle behind text. For any such element, currentColor makes the "background" trivially equal the "foreground" by construction, so the walk found a spurious 1.00:1 wherever a masked icon happened to pick up sampleable text. That happened here because of a real (separate, out of scope for this fix) HTML-escaping bug: the synthetic fixture's edge-case filename containing a raw `"` breaks out of `data="[[FILENAME]]"`, leaking markup as text children of the otherwise-empty .preview-icon span and an unrecognized <greaterthan> element the broken parse produces. That leak is real and made both elements eligible for sampling; skipping masked elements in the background walk makes the walk find the same true ancestor surface every other passing text element already clears against. Diagnosed by downloading the exact fixture CI's dump job produced (GH Actions run 31745292239) and reproducing the 1.00:1 locally against that fixture with plain diagnostic instrumentation: this branch's own fixture predates #459's icon refresh entirely, which is why "8/8 green locally" and "2/8 red in CI" were both true — pull_request's default checkout tests the PR merged with current main, not the branch alone.
rule.style iterated longhand-by-longhand: Chromium stores a shorthand containing var() (e.g. border: 1px solid var(--color-border-strong)) as a pending-substitution value, so every expanded longhand serialises to "". Scanning rule.style.cssText instead sees the literal var(...) text regardless of shorthand expansion. Confirmed by mutation: before the fix the scan found 28 of 34 var() references; after, all 34. Deleting --color-border-strong from HTMLTemplates.swift's :root (both light and dark blocks) now makes the test fail, naming the token; previously it stayed green.
The XCHR_UPDATE_SNAPSHOTS=1 branch wrote the golden and returned, so a refresh run was unconditionally green — writing bytes proves nothing about whether the new content is correct. XCTFail after a successful write so CI can never pass while the env var is set, and a developer refreshing locally is prompted to re-run without it for a real verdict.
GATING_IMPACTS = [] (correctly, per #440) makes the assertion expect([]).toEqual([]) — it cannot fail regardless of what axe finds, but the old name ("report has no critical or serious accessibility violations") claimed a guarantee the test does not provide. Renamed to describe the gate's actual state and expanded the comment to record all six known findings (image-alt critical x6, frame-title serious, heading-order/landmark-one-main/region moderate, empty-heading minor) so the debt is legible without re-running the suite.
SyntheticResultTests.testCoversHostileAttachmentFilename asserts the
fixture contains a filename with " ' < > & — but nothing asserted the
render escapes it, and it does not: HTMLTemplates.swift interpolates the
raw filename into onclick="showText('[[SOURCE]]')" unescaped, so the
embedded double quote breaks out of the attribute. The committed goldens
already contain this broken markup.
Adds a regression test wrapped in XCTExpectFailure recording the defect
(HTMLTemplates.swift / Attachment.swift, out of scope here) without
turning the suite red. The moment the escaping is fixed, XCTExpectFailure
flips this into a hard failure — an unexpectedly-passing expected
failure — which is the loud signal that the test should be promoted out
of the wrapper.
Whole-branch review found five claims in the spec the delivered work does not satisfy. Recorded as a dated Amendments section rather than editing history: fixture attachment coverage (PNG/text only, not video/HTML), behavioural assertions (2 of 3 shipped — no attachment-click-populates- preview test), contrast pairing discovery (sampled from one static DOM state, not the cascade; --color-text-secondary and --color-accent-soft are never exercised as text colour in the fixture's default render), axe moderate/minor reporting (console.log, not $GITHUB_STEP_SUMMARY), and Sequencing (PR #456 merged first and is this branch's merge-base, so the suite did not land before #456 as planned — #456's claims were verified retroactively instead, and confirmed sound).
"CI runs exactly these two commands, so a green run locally means a green run on your pull request" stopped being true once the Visual workflow landed. Corrected the claim and documented the two layers CONTRIBUTING.md was silent on: template snapshots (XCHR_UPDATE_SNAPSHOTS=1 to refresh, and why a refresh run always fails) and the Playwright browser layer (dump via XCHR_VISUAL_DIR swift test --filter VisualFixtureDumpTests, then npm ci + npx playwright test in visual/).
bundleNames: [String] = ["Synthetic"] put a test fixture's name into
production source as a default value. Made it a required parameter and
updated the three callers (SummarySeamTests, TemplateSnapshotTests,
VisualFixtureDumpTests) to pass "Synthetic" explicitly — the goldens'
<title> is unchanged because the value itself didn't change, only where
it's supplied from.
Also mirrored the path-based initialiser's identifier shape —
.appending("bundle\(index)").appending("action0") — instead of the
unrelated run-\(index), so the goldens pin an identifier set a real
report could actually produce. This does change the goldens: every
derived id/toggle/activities hash shifts with the path string. Regenerated
via XCHR_UPDATE_SNAPSHOTS=1 and diffed to confirm every changed line is
only a 32-hex-char identifier, nothing else.
swift build --build-tests warned "found 2 file(s) which are unhandled" for Tests/XCTestHTMLReportTests/Snapshots/*.html once those goldens existed: SwiftPM saw them under the target's source directory but they are read directly by path (SnapshotSupport.swift), not vended as Bundle.module resources. exclude: ["Snapshots"] tells SwiftPM to leave the directory alone.
Rebased onto origin/main (f442e8e), which merged #459 mid-execution of this branch's plan: an icon refresh adding status-glyph and icon tokens (SVG masks replacing base64 PNGs), a responsive @media (max-width: 700px) breakpoint, and type-derived attachment labels. TemplateSnapshotTests correctly caught the drift (Snapshot index/index-inline changed). Refreshed with XCHR_UPDATE_SNAPSHOTS=1 swift test --filter TemplateSnapshotTests (which itself fails on purpose per the FIX-2 change), then re-ran clean and read both goldens in full before committing: well-formed, properly closed, the hostile-filename markup this branch's expected-failure regression test depends on is still present and unescaped.

Limit the .xcresult requirement to fixture-backed tests.
The section first states that the Swift test suite requires real .xcresult bundles, then explains that snapshot and visual tests use synthetic fixtures. This makes the initial command sequence appear mandatory for every Swift test. Clarify that only fixture-backed tests require .xcresult bundles.
Proposed wording
-The Swift test suite runs against real `.xcresult` bundles. Generate them once,
-then run the tests:
+The fixture-backed Swift tests run against real `.xcresult` bundles. Generate
+them once, then run the full test suite:📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Document the Playwright browser installation step.
After npm ci, add npx playwright install chromium before npx playwright test. Without this step, a clean checkout can lack the Chromium binary required by Playwright.
