[SamGu-NRX]

These are review comments on already-merged BaseScanning iOS PRs that were never addressed. Most of them are about what the person scanning sees: the review gate, the aim card against the ring and arrow, the walk-out card, the AR result's chevron, and the step the aim lines ask for. Each original PR has its own section below. All repairs target alpha; beta is untouched.

Companion #237 merged into alpha at 53d2f50. This branch merges that alpha commit with merge commit d5d137ed008e60c61123e7175f4e55390a3c9322. Both debug launch routes share one cached result and one Group, and aim advice uses the trimmed requested window in cues for both normal and review frames.

#131: Review: soft gate, window Not sure, and an assumed 3 ft AC footprint

Codex thread, Aiden's review, Should-fix 1 and 2.

On "Anything else near your meter?", the first "Looks complete" with a question unanswered points to it and the next tap sends. That warning was spent once per screen. If the homeowner answered everything and then added a window, the next tap sent without pointing to the new question. With two unanswered windows, answering the outlined one removed the outline instead of moving it to the other.

The gate now re-arms once every question has an answer. While the warning is up, the outline follows whichever question is first without an answer (MarkFeaturesScreen.swift). The second tap still sends. The lost-place line now says "finish with Looks complete" rather than promising that one tap sends.

#120: hold a walk aim until it is met or stalls

The second-position reserve remains shared by both aim branches, but its title is now "Step sideways, look again". The previous sentence wrapped to two lines even at default text size, growing every aim card by about 28 pt and replacing the fixture's ring with an arrow. The shorter title measures 264.98 pt in the actual .SFUIRounded-Bold 22 pt title font. It fits the 297.3 pt CI text budget at a 402 pt screen width and a conservative 270.3 pt budget at the narrowest supported iPhone width of 375 pt. A constrained text-layout probe measures one line at both widths. The existing testAimRingShowsProgressAndItsLegend is unchanged; only the AX1 toggle test's expected copy changed.

The folded-title reserve finding is addressed by keeping nonempty reserved titles laid out whether or not a separate folded lead is present. Current live ground and wall aim cards have no separate folded lead, so their reserve was already retained. The new AX5 UI fixture deliberately exercises the combined card contract, cycling ring, arrow and covered titles for the same ground target and asserting a constant enclosing card height. Reserved titles remain hidden from accessibility.

The second-position title reserve is fixed in 875615d9. Both ground and wall aims now share their reserve before either advice branch or the nil-hint return, and include the named aimSecondPosition title. The same target can gain and lose that advice without moving the card or camera. The AX1 toggle regression fails against 686c44bb, where the card grows from 165.7 to 206.7 pt, and holds one height after the fix. The real AX5 screen still leaves 212 pt of visible camera, above the existing 150 pt requirement; marker bounds and scrolling checks pass.

Greptile: review frames keep stale advice, Greptile: ring wording can mismatch the overlay, Aiden's review.

Step-back and step-aside advice on review frames. A replay frame shown for review re-aimed the card's direction but kept the step-back and second-position flags from the last live frame. GuidancePlanner.cues(for:) now works both out from the camera it's given, and the review path rebuilds the whole hint from them while keeping the direction's edge hysteresis (51e8e79). Check: cuesJudgeTheAdviceFromTheCameraGiven.

The card names the marker that's drawn. The card's title came from the camera's angle to the target (AimHint), but the overlay chooses between the ring and an arrow from the open camera between the card and the actions. Near the card or an edge, the card could say "Put the ring on the strip" while an arrow was drawn. The overlay now reports the marker it draws, and the walk's card takes its direction from that (be7f47e):

• A drawn ring counts as on screen.
• An arrow standing in for a target the angle calls on screen gives its own direction.
• Every drawn arrow supplies its own direction, including behind-camera targets.
• When Details at AX5 covers the camera, an on-screen engine hint uses the step's title instead of naming an absent ring. Above and below keep their engine direction. A visible note says "The camera view is below. Close Details or scroll." only when expanded Details leaves less than the arrow's 52 pt of visible camera. A missing projected direction or short camera area without open Details does not give that advice.

An arrow turns into a ring only 12 pt inside the ring's bounds, and the arrow's direction keeps the hint's axis bias, so neither the marker nor the title swaps several times a second at that edge. The margin applies only on aim steps (2d81733). Check: testTheAimCardNamesWhatIsDrawn, which plants an engine hint that disagrees with the drawing (-uiDemoAimHint).

One step instruction. Covered under #117 below.

Still open: when the walk asks to tilt up over the meter. Today it asks only near the meter after both ends are marked, which the usual flow rarely reaches. That's a change to the walk's order, so it's written up for Sam as D3.

The latest arrow/card finding is fixed by using every drawn arrow's direction, including its explicit horizontal turn for behind-camera targets. Details now closes for a new aim by carrying exact ground/wall target coordinates through the instruction; marker title changes for the same target retain it. Three screen-state regressions cover a conflicting off-screen hint, same-target title swaps and target changes with identical rounded distances. All three regressions passed locally under the guard after correcting the marker fixtures.

#117: green hold, legend in the card stack, narrower progress window

Aiden's reviews and follow-up comments.

The tilt-down card and the ring's legend asked for "a small step sideways", while the second-position title asked for "one step to the side". A stretch counts only once it's seen from two places 0.25 m apart, and auto-capture keeps a frame for its place only 0.5 m from the last kept one (AutoCaptureConfig.spacingMeters), so a shuffle can fall short of both. All three lines now ask for a step to the side, about the 2 ft step the field runbook uses (cf3a3ad). The green hold and the legend move were already on alpha.

#168: treat a corridor's far wall or a side yard's fence as where the space ends

Greptile thread.

A walk-out request's "The space ends about … out" line was latched for the whole request, so ARKit's plane refinements couldn't re-arm the reply lock every frame. If ARKit later moved or removed that plane, the card kept saying the walk was impossible and hid the dotted line. SlowRelease (HouseScanKit) now holds the first reading still while a block is found and clears it once none has been found for 2 s (eb3f270). The 2 s is a guess at what reads calmly, not a measurement. Check: SlowReleaseTests.

#137 and #132: the AR result's chevron and who draws the result

Aiden's review of #137, Aiden's review of #132.

"See it on your wall" judged the spot as in view, and placed its chevron, in fixed bands 260 pt from the top and 160 pt from the bottom. From xxxLarge text up the card passes 260 pt, so a spot under the card counted as in view and got no chevron. The screen now uses the open camera measured by CameraWindow, as the walk's aim ring does.

The later accessibility-only rule that always showed an off-screen note caused a feedback loop at AX5. Opening Details covered the spot and added a five-line "Tilt the phone up" note. After Details closed, the note itself kept the spot covered and pushed Done off screen. 6850e12 decides the note against the camera the card would leave without it. OpenCameraWithoutNote reconstructs that window from the measured layout, including scroll limits, and has Kit regressions. The note takes its room from the camera rather than pushing Done away.

With Details closed, the card gives turn advice only when the chevron and its words cannot be drawn, at every text size. At AX1 through AX4 it therefore no longer repeats a drawn chevron. With Details open it never gives turn advice. 055e497 shows "The camera view is below. Close Details or scroll." whenever the chevron cannot be drawn with Details open, including windows that fit the 52 pt disc but not its label, addressing Greptile's P2. A drawn chevron's VoiceOver label now names the direction to turn.

The caretaker arrow-direction finding showed that visibility used the open window while direction still used the full camera center. With large text or Details open, a spot below that center but above the window produced a downward arrow. HouseScanKit's OpenCameraDirection now computes projected directions from the visible window's center. A behind-camera spot keeps the camera-derived fallback. Package regressions cover the reversed-direction case, a covered optical-center spot, both side edges, Done and an already-visible spot.

The sentence and chevron share the last named direction, applying axis hysteresis to diagonal jitter. Kit tests cover jitter in all four directions and deliberate axis changes. A spot that was off screen must move 12 pt inside the camera window before counting as in view again; Kit tests cover this entry margin at each edge and re-entry farther inside. The 12 pt margin is unmeasured on a phone. OpenCameraDirection.classify returns only the four possible directions, removing the app's unreachable failure branch.

The off-screen-note UI test moved from AX3 to AX5, where the chevron and label do not fit. A new AX5 regression opens and closes Details and checks that the note does not keep itself up and Done stays reachable. A new AX3 "chevron or note" regression checks that an off-screen spot has a written direction through either the chevron's VoiceOver label or the card note. These new UI regressions have not been run locally; the new AX5 regression's failure on d5d137ed is also unverified locally.

The AR scene's chain now counts as anchored only while the meter's anchor is still in the session. When ARKit drops the anchor, the screen's own drawing takes over instead of trusting an entity that still reports itself anchored.

#53: keep reviewed marks past a marked end

Aiden's review.

The server answers objects_not_used for marks with no footprint past an unexplored end, but the app never decoded it, so the homeowner had no sign a window or gas meter wasn't counted (#42). HouseScanKit now decodes the list, which is optional in schema 1.0. The result's Details lists each mark in the server's words under "Not counted" (63fab7e). featuresPastEnds also kept stale IDs after a delete or a reset; those paths now refresh or clear it. Checks: decodesObjectsNotUsed (schema-valid and round-trips), the markFeatures-pastEnd screen state, and testAMarkTheServerSetAsideIsListedAsNotCounted.

The "Not counted" hint now explains why marks were set aside without prescribing rescanning or contradicting "Capture it now". D1 remains open.

The caretaker fixture finding exposed a false past-end example: the fixture flagged the in-bounds gas meter while the result described a window elsewhere. The demo now adds a window spanning -4.1 to -3.3 m, wholly beyond the wall's left end at -2.9 m. The review expectation identifies that window's row, its 12 ft distance and its warning; the result expectation identifies the same window.

#18: Research handoff: live survey findings, options and tested prototypes

Coverage replay could leave kept camera sightings beyond a cleared end clipped away. Both setEnd and clearEnd now rebuild regular and depth coverage from every kept regular frame against the new bounds, preserving skipped and withdrawn cells. Rebuilding replaces sightings rather than merging duplicates. Four Kit regressions check restored wall/ground cells, repeated clearing, clearing then re-marking, and preserving precomputed sightings without kept frames. The restoration test fails on 6ceadcf.

Every end tap and clear replays synchronously on the main thread. Both repository journey/autopilot fixtures, synthetic-wall and synthetic-wall-lidar, contain 61 regular motion frames with normal tracking, so their median and largest count are both 61. Both are synthetic recordings; external HOUSESCAN_REPLAY inputs are not repository fixtures.

On an Apple M4 Pro Mac16,8, the same synthetic no-depth probe built with swift test -c release measured these medians over three set/clear cycles:

Retained frames	setEnd	clearEnd
61, largest repository fixture	11.20 ms	15.11 ms
100	18.50 ms	24.80 ms
1,000	185.19 ms	244.43 ms

Coverage maps are per wall. AutoCapture's 0.33 s minimum interval keeps at most about three regular frames per second, so a 60 s walk along one wall keeps at most about 180 frames. Linear interpolation between the measured 100-frame and 1,000-frame rows at 180 frames estimates about 33 ms for setEnd and 44 ms for clearEnd, roughly 35–45 ms. This estimate is below the 50 ms review bar, so the full-rebuild design stays. The 61-frame synthetic fixtures are not evidence of a realistic walk count. No real-walk frame count or iPhone timing exists. These are Mac Kit CPU measurements and an interpolation, excluding depth, capture, JPEG writes and UI scheduling. They replace the earlier debug-build timings.

Existing ground refinement also calls CoverageMap.updateWall and synchronously replays all kept cameras on the main actor. It runs only after a changed ground-plane snapshot yields the first valid measurement or a height change over 1 cm. The first measured ground can also clear heightError, causing another rebuild. There is no measured per-walk frequency or fixed timer. Replay fixtures carry no plane snapshots, so those ground/refit paths run zero times in their walks. Wall refitting is restricted to meter close-up and creates a fresh map before walk frames are kept; normal anchor corrections use apply without replaying. End taps therefore add the same kind of main-thread replay as ground refinement, but the source does not establish that the existing replay happens as often.

Regular-frame history remains unbounded: CoverageMap.observe retains accepted frames, ScanEngine.keep and KeyframeStore impose no count limit, and AutoCapture's 0.33 s interval limits rate only. The separate 300-frame depth-stream budget does not cap it. The past-end debug scenario now caches its result once per process, using the same engineCheckResult pattern as #237 and both routes are preserved by the alpha integration above.

A server past_end request clears its old end, so replay can bring old sightings back and start the request partly complete or with full progress. The new engine scenario calls beginServerGap with both cases. Full restored coverage does not immediately settle it: updateGap still requires a newly kept photo after the request began. This preserves option A's reused sightings without bypassing that existing fresh-photo condition.

Capture-test write ordering

Journey failures read capture state before the write they depended on finished. Coordinator reset tests now wait for persisted abandonment before releasing the held old reply, then submit the new photo. This establishes the late-reply schedule and preserves the fixture's one-held-reply contract. Withdrawal tests hold an already-received reply, avoiding a network timeout while the test controls its release, and require the saved abandoned state while the main actor's queued abandon task remains blocked. Recovery tests wait until disk state matches the uploader snapshot before reading it or making the folder read-only. The loopback also parks and releases replies under the same lock, so release cannot miss a reply still being computed.

The held-reply helper now records a test failure and throws a specific error for a second overlapping reply rather than crashing the process. Its regression verifies that the first reply remains releasable. Dead held-array assignments were removed, and the demo sample documentation is attached to the correct value.

#51: show the AR result anchored to the meter

Aiden's review.

The AR model hangs on the meter's anchor and follows its corrections. The rebuild test compared the wall in world coordinates, though, so an anchor correction over 5 cm rebuilt the model anyway, and a rebuild during the first 0.7 s cut the battery's rise short. The wall is now compared in the anchor's frame at build time and now (ScanEngine.inAnchorFrame), so only a change to the wall itself rebuilds the model (db6eccd). People occlusion, which nothing turns on yet, is now checked against the semantic set that would actually run.

#169: bring the UI test flake fixes to beta

Greptile thread. The code is on alpha too.

With -autopilotCantGetThere, the held-back frames were planned with each end at the farthest frame's own place. The engine puts the end through WalkedEnd.choose, which stops short of the phone when tracking is limited, the phone is far out from the wall, or it's more than 2 m past the kept views. The planner could then hold back frames for a gap the walk never asks for. ReplayPlanning.walkedEnds now runs the same chooser from the farthest frame each way (3152880). Check: WalkedEndsPlanningTests covers each cap.

#89: meter number read on device

Sam's thread.

Entering the close-up, a retake, a skip and starting over cleared the meter number but kept the brand read with it. The brand now clears with the number on each of those paths, and DemoEngine does the same (3e51e03). The brand is local display state and is never sent. No test covers this: the brand is never on screen after these paths, and the app has no unit-test target (see D2).

Answered without a code change

• #172, crowded legend stays inline: not a bug. ViewThatFits measures each candidate's ideal width, and a Text reports its ideal width unwrapped. I rendered the same footer structure with ImageRenderer across widths. It stays stacked below 548 pt and switches inline at exactly the width where every entry fits on one line, at one line's height. The wallWalk-fullLegend screen state also audits all three entries together.
• #155, ring under the stacked legend: fixed earlier. Since 50e1069, the ring is placed only in the open camera measured below the card and the legend (WayfindingOverlay.swift:148, CameraChrome.swift:75-80 on alpha). A ring that would sit under them becomes an arrow in the open camera (WayfindingOverlay.swift:155). The fixed rectangle that remains decides only whether to show the legend. It doesn't depend on the legend's own height on purpose: if it did, the legend could switch itself on and off. The card's words now follow the drawn marker (ios: hold a walk aim until it is met or stalls, and ask for the meter ground only near the meter #120 above).

Still open

These are written up with options and a recommendation in review-debt/opus/bs-ios-opus-decisions.md:

• D1: what the result leads with when missing evidence isn't tied to any check (#91 Aikido, #91 Codex).
• D2: an engine-level test for marks following anchor corrections (#119 Greptile and Aiden's reviews). It needs an app unit-test target, which means a CI workflow change.
• D3: when the walk asks to tilt up over the meter (#120 Aiden, Should-fix 2).

Risk

End changes replay an unbounded regular-frame history on the main thread. At the code-derived bound of about 180 regular frames for a 60 s per-wall walk, linear interpolation of the Mac Release measurements estimates roughly 35–45 ms. Measured medians reach 185 ms for setting an end and 244 ms for clearing it at 1,000 synthetic no-depth frames. No real-walk frame count, iPhone timing or depth-inclusive measurement is available. D1–D3 remain open. There was no real-device AR walk in this round.

Verification

AR off-screen-note follow-up at 055e4970d0b26d6aec344c193df55b3806a9e01f, following 6850e122:

• Neither commit was built or run locally because free disk was below the 8 GiB guard floor. Earlier local results below apply only to their named heads.
• CI's Build Release, unsigned step passed on both 6850e12 and 055e497. This is compilation evidence, not completed UI verification. The older run was cancelled after the later push.
• UI groups and Kit swift test were pending at handoff on 055e497. At the status check for this description update, the journey job's Kit step had passed; screenStates and photoProcessing UI steps were running, and journey UI was pending. No current-head UI result is claimed.
• The before-fix symptom is the original journey failure on d5d137ed, run 38660098414: ProvisionalPlacementUITests/testASpotSettledByAnEarlierAnswerIsStillAPossibleSpot, "folded again: Done isn't reachable". The new AX5 regression's failure on that head has not been verified locally.
• Added coverage includes OpenCameraWithoutNoteTests, the 12 pt entry-margin cases in OpenCameraDirectionTests, testTheOffScreenSpotInstructionStaysVisibleWithDetailsClosedAtAX5, testTheOffScreenNoteDoesNotKeepItselfUpAfterDetailsCloseAtAX5, and testTheOffScreenSpotAlwaysHasADirectionAtAX3. The first two are Kit tests; the three UI checks remain pending on 055e497.

Alpha integration at merge commit d5d137ed008e60c61123e7175f4e55390a3c9322, parents 0d36e995 and 53d2f50:

• Git reported three conflicts. HouseScanApp.swift now dispatches -engineGuidanceCheck and -enginePastEndReplayCheck through one static cached result and one Group. ScanEngine.swift retains both DEBUG scenario functions. GuidancePlanner.swift keeps the ios: fix review debt on the walk, review and AR result screens #241 move of aim advice into cues, applying fix(ios): address merged capture and guidance review debt #237's trimmed aimWindow there and removing duplicate advice from update.
• All eight paths changed by both branches were inspected against both parents. WallWalkScreen.swift and ScreenStatesUITests.swift are byte-identical to the pre-merge ios: fix review debt on the walk, review and AR result screens #241 head. The auto-merged engine retains capture identity, interruption generations, pause records, frozen question cues and the full explicit refusal span. Independent read-only source review found no actionable merge defects. No unmerged index entries or conflict markers remain. Other alpha changes are imported unchanged by the merge.
• Guarded Kit swift test --package-path ios/HouseScanKit --jobs 2 -Xswiftc -warnings-as-errors passed 950 tests in 128 suites in 101.391 s, with one expected known issue. Guarded generic-iOS Debug app build and generic-simulator UI build-for-testing passed using /tmp/bs-ios-241-alpha-build.sh, the same commands below with derived-data paths /tmp/bs-ios-241-alpha-device-dd and /tmp/bs-ios-241-alpha-ui-dd.
• 23 isolated-simulator checks passed in 138.549 s: unchanged ring/progress/legend, AX1 second-position height, AX5 folded card height, AX3 off-screen sentence, PastEndReplayTests, and all EngineGuidanceTests. Both cached debug check routes were exercised. The shared simulator was untouched.
• Commands ran through python3 ~/.long-run/obvious-fleet/review-debt/bin/run-guarded.py --min-free-gib 8 --, with /bin/zsh /tmp/bs-ios-241-alpha-package.sh, /bin/zsh /tmp/bs-ios-241-alpha-build.sh, then /bin/zsh /tmp/bs-ios-241-alpha-ui.sh. The UI script uses test-without-building, isolated simulator 2547EA37-5D00-41FD-BCBC-DB249CA358FA, -jobs 2 -parallel-testing-enabled NO -collect-test-diagnostics never, the four named screenStates selectors and both engine-test class selectors, with server/replay environment cleared. Logs bs-ios-241-alpha-package.log, bs-ios-241-alpha-build.log and bs-ios-241-alpha-ui.log identify both parents, tested source hash and final merge SHA. New-head CI results are pending.

Short-title follow-up at 0d36e9953b40d34b4104b1eb7725a2a921747839:

• Unsigned generic-iOS Debug app build and generic-simulator UI build-for-testing passed through run-guarded.py --min-free-gib 8 --, using /tmp/bs-ios-241-short-title-build.sh. The commands match the earlier build commands with /tmp/bs-ios-241-short-title-device-dd and /tmp/bs-ios-241-short-title-ui-dd.
• All three required UI checks passed in 60.613 s on the isolated iPhone 17 simulator 2547EA37-5D00-41FD-BCBC-DB249CA358FA: unchanged testAimRingShowsProgressAndItsLegend, testSecondPositionAdviceKeepsTheSameAimCardHeightAtAccessibilitySize, and testAimCameraStaysOpenAtLargestTextSize. The last check leaves 212 pt of visible camera, above the 150 pt minimum. The shared simulator was untouched. Rendered attachments were inspected.
• The first UI batch stopped with guard exit 75 when free disk fell below 8 GiB. After removing only owned disposable build intermediates and waiting eight minutes for more than 10 GiB free, a fresh result bundle completed all three checks.
• UI command: the same guard with /bin/zsh /tmp/bs-ios-241-short-title-tests.sh, using test-without-building, -jobs 2 -parallel-testing-enabled NO -collect-test-diagnostics never and the three named -only-testing:HouseScanUITests/ScreenStatesUITests/... selectors. Logs bs-ios-241-short-title-build.log and bs-ios-241-short-title-tests-retry.log identify the tested source and final commit; bs-ios-241-title-measure-final.log records the font-width and constrained-height measurements.
• Saved CI evidence on ceec8f78 passed 37 of 38 screenStates tests. Only the ring-progress test failed, with "the aim ring must show its progress"; its hierarchy and recording showed an arrow under the enlarged card. testTheOffScreenSpotInstructionStaysVisibleWithDetailsClosedAtAX3 passed there, so the earlier AX3 failure is resolved. Current-head CI results are pending.

Release-cost follow-up at ceec8f78e71ff9fa51155a36622f8f67816e7e3e:

• The release probe passed, and all four clear-end restoration/idempotence Kit regressions passed in Release in 0.003 s. The package production source is unchanged from 875615d9; the full earlier run passed 933 tests in 127 suites. The temporary probe source, fixture counts and raw timings are retained in bs-ios-241-release-probe.swift, bs-ios-241-release-fixture-counts.json and bs-ios-241-release-probe.log in the local triage folder.
• Probe command: python3 ~/.long-run/obvious-fleet/review-debt/bin/run-guarded.py --min-free-gib 8 -- /bin/zsh /tmp/bs-ios-241-release-probe.sh. Its inner command is swift test --package-path ios/HouseScanKit -c release --jobs 2 -Xswiftc -warnings-as-errors --filter Review241RebuildProbe, with the temporary measurement test placed in the Kit test target. The four regression checks use the same guarded Release command with --filter 'CoverageMapTests/clearing'. The probe was removed after measurement.
• The unsigned generic-iOS Debug app build passed through the guard after caching the debug scenario. Command: python3 ~/.long-run/obvious-fleet/review-debt/bin/run-guarded.py --min-free-gib 8 -- /bin/zsh /tmp/bs-ios-241-release-app-build.sh, whose inner xcodebuild command uses the project and scheme below, -configuration Debug -destination 'generic/platform=iOS' -derivedDataPath /tmp/bs-ios-241-release-device-dd -jobs 2 CODE_SIGNING_ALLOWED=NO COMPILER_INDEX_STORE_ENABLE=NO build. Guard logs identify the source and final commit. No UI-test source changed in this follow-up.

Second-position follow-up at 875615d9816d26049237a1788d98b91091e9c496:

• Guarded unsigned Debug app build and UI build-for-testing passed, using the commands below with /tmp/bs-ios-241-second-position-device-dd and /tmp/bs-ios-241-second-position-ui-dd. Log bs-ios-241-second-position-push-build.log begins with the full commit SHA.
• Three focused checks passed in 57.134 seconds: testSecondPositionAdviceKeepsTheSameAimCardHeightAtAccessibilitySize, testAimCameraStaysOpenAtLargestTextSize, and testFoldedAimCardKeepsItsHeightAcrossMarkerTitlesAtAX5. They check false → true → false → true advice at AX1, actual window-clipped camera height and marker bounds through twelve scroll positions at AX5, and the other marker titles at AX5. All three screenshots were inspected.
• testTheAimCardNamesWhatIsDrawn also passed in 28.945 seconds. Its first ring fixture needed correction under the longer reserve: the default-size legend consumed space around its old point. It now explicitly projects the target at the optical center at AX1, where the legend folds under Details, while retaining the conflicting engine hint. The real ring, arrow and covered assertions remain. No timeout changed.
• Red baseline: the new toggle test uses the unchanged 686c44bb ScanCopy plus only its fixture/test additions and fails with a 41 pt card-height change. The fixed source passes all three toggles. Logs bs-ios-241-second-position-baseline.log, bs-ios-241-second-position-tests.log, and bs-ios-241-second-position-marker-AX1.log record the source SHA and tested diff. Exact UI commands use the guard and offline flags below with these named -only-testing selectors; the first three use test-without-building, and the marker check uses test.
• HouseScanKit source and package tests are unchanged from 686c44bb, which passed 933 tests. That passed suite was not rerun. Current-head screenStates, journey and photoProcessing CI results are pending. The title and reserved-title set use the requested words; no new layout or copy trade-off was chosen.

Earlier verification on 686c44bb follows.

On 686c44bb38e7bc79ceb5bc2ecf552153bde6e4ac:

• HouseScanKit passed 933 tests in 127 suites in 114.895 seconds, with one expected known issue from the held-reply helper's failure-reporting regression. Command: python3 ~/.long-run/obvious-fleet/review-debt/bin/run-guarded.py --min-free-gib 8 -- swift test --package-path ios/HouseScanKit --jobs 2 -Xswiftc -warnings-as-errors.
• The unsigned Debug app and UI test target build passed through the same guard.

UI command changes the destination to 'generic/platform=iOS Simulator', the derived-data path to /tmp/bs-ios-241-manager-ui-dd, adds HOUSESCAN_SERVER_URL=, and uses build-for-testing.
• Four targeted checks passed in 52.981 seconds on an isolated iPhone 17 / iOS 26.5 simulator: testTheOffScreenSpotInstructionStaysVisibleWithDetailsClosedAtAX3, testTheAimCardNamesWhatIsDrawn, testFoldedAimCardKeepsItsHeightAcrossMarkerTitlesAtAX5, and testPastEndReplaysOldCoverageButStillNeedsAFreshPhoto. The existing journey group discovers the new engine check, without a new target or workflow. Group partition check passed with no overlap or missing tests. The shared simulator was untouched.
• Targeted inner command: xcodebuild -project ios/HouseScan.xcodeproj -scheme HouseScan -configuration Debug -destination 'platform=iOS Simulator,id=2547EA37-5D00-41FD-BCBC-DB249CA358FA' -derivedDataPath /tmp/bs-ios-241-manager-ui-dd -resultBundlePath ~/.long-run/obvious-fleet/review-debt/triage/bs-ios-241-manager-ui-fixed.xcresult -jobs 2 -parallel-testing-enabled NO CODE_SIGNING_ALLOWED=NO COMPILER_INDEX_STORE_ENABLE=NO HOUSESCAN_SERVER_URL= -only-testing:HouseScanUITests/ScreenStatesUITests/testTheOffScreenSpotInstructionStaysVisibleWithDetailsClosedAtAX3 -only-testing:HouseScanUITests/ScreenStatesUITests/testTheAimCardNamesWhatIsDrawn -only-testing:HouseScanUITests/ScreenStatesUITests/testFoldedAimCardKeepsItsHeightAcrossMarkerTitlesAtAX5 -only-testing:HouseScanUITests/PastEndReplayTests test. It ran through run-guarded.py --min-free-gib 8 --, with TEST_RUNNER_HOUSESCAN_SERVER_URL and TEST_RUNNER_HOUSESCAN_REPLAY cleared.
• CI screenStates on f148641a passed 36 of 37 tests. Only testTheOffScreenSpotInstructionStaysVisibleWithDetailsClosedAtAX3 failed, at line 796 while looking for the card sentence. It used AX2, not AX3. Correcting the category to AX3 also reproduced the failure locally in 9.908 seconds: the recorded hierarchy showed a visible ar.spotDirection chevron and label, so the old fallback-only callback supplied no card sentence. At 686c44bb, the app supplied that sentence at all accessibility sizes whether the chevron fit or not, and the corrected test passed in 5.824 seconds without a timeout change. That rule is superseded by 6850e12 and 055e497: with Details closed, the note now appears only when the chevron cannot be drawn. The earlier screenshot records the superseded behavior.
• New-head screenStates, journey and photoProcessing CI results are pending. On prior f148641a, photoProcessing passed; journey was still running at the last check. The prior screenStates failure is addressed above.
• Logs: bs-ios-241-manager-package.log, bs-ios-241-manager-final-builds.log, bs-ios-241-manager-ui.log for the red AX3 reproduction, bs-ios-241-manager-ui-fixed.log for the four passes, and bs-ios-241-manager-rebuild-probe.log for replay timing. Guard logs record the source SHA and tested contents; the verification JSON ties pre-commit runs to this commit. Independent source reviews and the complete staged diff/deslop pass found no blockers; git diff --check passed.

Earlier results apply only to their stated heads. On 6ceadcf, photoProcessing passed 10/10, screenStates passed 35/35, and journey completed with 79 passes, one external-replay skip and the pre-existing Vision failure. The same FullFlowUITests/testPracticeMeterFromReplay failure, com.apple.Vision 9: Could not create inference context, also occurs on unchanged alpha at 3c33ad7 with the same simulator and seed. The clear-end restoration regression fails on the pre-fix 6ceadcf CoverageMap; all four replay/idempotence regressions pass now. Earlier evidence remains in local triage verification records.

UI changes

iPhone 17 Simulator, iOS 26.5, -uiDemo -uiDemoFreeze. Before is alpha at cde8450; after is this PR at 2d81733.

Every aim line asks for one step to the side (#117). Same state, -uiDemoPhase wallWalk -uiDemoAim.

Before	After

The card names what is drawn (#120), after only. These states plant an engine hint that disagrees with the drawing (-uiDemoAimHint), a flag alpha doesn't have. On alpha the left one would read "Tilt up a little" over a visible ring, and the right one "Put the ring on the strip" with only an arrow on screen.

Ring drawn, engine says "above"	Arrow drawn, engine says "on screen"

The aim-card mismatch and same-target Details regression were rendered locally and their screenshots inspected. The result-screen arrow has passing package coverage, and the corrected past-end window's result-card UI test passed locally.

Not captured here: the review gate after a tap (#131), the lost-place line and the past-end row (both below the fold on the review panel), "Not counted" under Details (#53), and the AR chevron at large text (#137). The first four are covered by the new UI tests, which attach their own screenshots in CI. The earlier local AX3 and AX5 screenshots show the behavior before 6850e12 and 055e497, not the current note decision. No local build, UI run or new rendered capture exists for those two commits because disk was below the 8 GiB guard floor. Their AX5 note/Details regressions and AX3 "chevron or note" test are awaiting UI CI results.

Summary by CodeRabbit

• New Features

  • Result details explain which marks were set aside and why.
  • Guidance cards show how to find proposed spots outside the camera view and better match the displayed ring or arrow.
  • Review guidance explains when the phone’s position is lost and when marks were not counted.
  • When Details covers the camera view, guidance explains how to restore a clear view.

• Bug Fixes

  • “Looks complete” highlights unanswered questions before confirmation and resets the warning when all questions are answered.
  • Space-end readings remain visible briefly when scanning conditions fluctuate.
  • Results and guidance stay more consistent as the phone or scan boundaries change, including restoring observations when a boundary is cleared.
  • Guidance and camera indicators stay aligned as targets move, and Details closes when the aim target changes.

📝 Walkthrough

The changes update iOS scan guidance, result details, scan state, coverage replay, and replay planning. They add server-provided messages for unused marks, adjust aim and spot indicators, and update related tests and demo states.

Changes: Aim guidance and camera indicators

Layer / File(s)	Summary
Camera-specific guidance cues ios/HouseScanKit/Sources/HouseScanKit/Guidance/GuidancePlanner.swift, ios/HouseScanKit/Tests/HouseScanKitTests/GuidancePlannerTests.swift, ios/HouseScan/Runtime/ScanEngine.swift	GuidancePlanner.cues(for:coverage:camera:) calculates aim cues from the supplied camera. Review-frame refresh recomputes the full hint. Tests cover camera-dependent advice.
Aim marker placement and reporting ios/HouseScanKit/Sources/HouseScanKit/Overlay/OpenCameraDirection.swift, ios/HouseScan/UI/Camera/WayfindingOverlay.swift, ios/HouseScan/UI/Camera/CameraOverlays.swift, ios/HouseScan/UI/Screens/WallWalkScreen.swift, ios/HouseScanUITests/ScreenStatesUITests.swift	WayfindingOverlay reports ring, arrow, covered, or absent marker states. WallWalkScreen adjusts guidance to match the reported marker.
Aim card state and title layout ios/HouseScan/UI/Components/InstructionCard.swift, ios/HouseScan/UI/Components/CameraChrome.swift, ios/HouseScan/UI/Copy/ScanCopy.swift, ios/HouseScan/UI/Preview/DemoEngine.swift, ios/HouseScan/UI/Preview/UIDemo.swift, ios/HouseScanUITests/ScreenStatesUITests.swift	Instructions reserve alternate titles and identify aim targets. InstructionCard reports disclosure state and measures note height. Demo controls and UI tests cover card states and layout.
Camera-window geometry and spot directions ios/HouseScanKit/Sources/HouseScanKit/Overlay/OpenCameraWithoutNote.swift, ios/HouseScan/UI/Screens/ResultARScreen.swift, ios/HouseScan/UI/Copy/ScanCopy.swift, ios/HouseScanKit/Tests/HouseScanKitTests/OpenCameraWithoutNoteTests.swift, ios/HouseScanKit/Tests/HouseScanKitTests/OpenCameraDirectionTests.swift	CameraChrome tracks camera-window and note geometry. SpotDirection positions its chevron within the available camera window or reports written directions.

Review and result presentation

Confidence Score: 5/5

[Medium impact] The changes appear safe to merge; no new actionable defects were found.

Summary

This PR fixes guidance, review prompts, and AR result screens on iOS.

• The review gate points to new unanswered questions before sending.
• Walk aim cards follow the ring or arrow shown on screen.
• The AR result points toward spots outside the open camera.
• Result details list marks the server did not count.
• Walk-out advice stays briefly while the scan boundary shifts.
• Clearing a scan end restores sightings and replay uses the walk's end choice.
• Scan state and AR results follow the active meter and session.
• Capture tests wait for the replies and saved state they depend on.

Since the previous review, the change removes marker-specific wording when no marker is visible and adds two focused UI checks. No new actionable issues were found. The earlier unnumbered threads remain addressed. This was a source review; iOS UI checks were not run here.

Clear aim guidance when no marker is displayed.

Clear aim guidance when no marker is displayed.

When WayfindingOverlay reports .covered, shownHint clears only .onScreen, so a previous directional hint remains while no marker is drawn. When it reports nil, the guard returns state.guidanceHint unchanged and can preserve stale aim guidance. Clear only hint.aim for both reports so ordinary guidance remains visible.

Confirmed and fixed in 3424859. The rule that every drawn arrow controls the card still holds. A covered or absent current marker is different: there is no arrow whose direction the card should name. Only hint.aim is cleared; second-position and step-back advice remain unchanged.

Before	After	Why
At AX5, opening Details hid the above arrow but left "Tilt up a little" beside the camera-obstruction notice.	The card shows the step's title and keeps the obstruction notice. Closing Details restores the drawn arrow's direction.	The old title described a marker that was no longer drawn.
With no target, the engine's above hint still supplied "Tilt up a little".	The card shows the step's title without a ring or arrow.	An absent marker must not supply marker-specific guidance.

Both new regressions failed against the unchanged 753531d production code, with four failed assertions showing the retained title. With the fix, all 11 focused UI tests passed, including both regressions, marker/card agreement, target/step hysteresis, reserved card heights, new-target Details closure, ring progress and largest-text layouts. Ran on a disposable iPhone 17 Pro simulator with iOS 26.5 and Xcode 27.0 through run-guarded.py --min-free-gib 8. No existing assertion was removed or weakened.
