What changed

Adds experiments/evals/: evals on public data that measure how accurately a phone can measure a house wall and whether the app's coverage map reports only what it saw, plus the kit that scores the team's field test. Each row below regenerates with one make target from a clean checkout. The README is a one-screen summary; METHODS.md holds the method, results and prerequisites for each question, and every result file records its dataset URLs and sha256s.

Command What it measures Headline
make drift ARKit position error after walking 3, 10, 20 and 30 ft (ADVIO, 2018 iPhone 6s) p90 18.6, 55.7, 94.6 and 132.6 in: two to three times the server's 0.16 ft per ft allowance. The reference's own noise inflates it.
make modern-arkit A current iPhone's ARKit scale and position error (MARViN, iPhone 14 Pro Max) Scale within 2% of the dataset's reference on 30 of 35 walks; within one site the ARKit / reference ratio varies 0.3% to 0.8% between walks. That is disagreement with the reference, not a bound on ARKit's error. Position p90 8.6, 13.4 and 18.5 in after 10, 20 and 30 ft on trusted walks, inside the allowance. The reference's scale cannot be checked independently to 2%, and this phone has LiDAR.
make recon Learned single-photo depth (MoGe-2, Depth Anything 3 metric) against ETH3D's laser scans Model scale is 4% to 12% off. One photo scaled by one taped distance: median 1.8 in, p90 13.6 in on walls, 1 to 3 m spans. Averaging more photos placed with true poses makes it worse (p90 5.2 in with 1 photo, 11.9 in with 8, on the same seed groups).
make pose-priors Whether AR poses fix that scale: MoGe-2 rescaled by points triangulated with the poses, 8 photos Wall p90, 1 to 3 m spans: exact poses 2.8 in [2.0, 4.6]; a simulated 2% pose scale error (not a measured phone) 5.0 in [3.7, 6.9]; the 2018 phone 10.8 in [8.6, 13.1]. Not 4 in at realistic pose error, and these assume perfect feature matching.
make frames Which photos to keep Photos with the wall within 6 m cut a single photo's p90 on 3 to 10 m spans from 38.7 to 14.8 in.
make coverage Whether the app's CoverageMap (ios/HouseScanKit at beede15, run unedited) claims wall that no photo saw, against the laser scan's visibility Yes: 1.1 ft of a 19.3 ft wall, against a 0.5 ft bar set before the run. The wall's base is hidden behind scaffold footings, because CoverageMap.swift lines 241 to 248 check range, angle and image bounds but not occlusion. The ground band and ETH3D facade could not be tested.
make coverage-options Which rule change removes that, and how much seen wall it gives up See the table below.
make map3d The same test for the app's 3D map (Map3D, t3/ios-map3d at 66cdcba), LiDAR path, fed depth rendered from the laser scan No wall claimed that no photo saw (0.0 ft, where CoverageMap claimed 1.1 ft). It misses 8.9 ft, 5.5 ft behind pilasters. Ground and overhead are untested; the non-LiDAR path is not measured.
make field One Measure Lab session plus its tape survey, scored by PR #4's harness, with the phone's AR scale error and a 95% bound Proven on a synthetic session built in the field sheet's order (make field-dryrun): a planted 1.5%-short scale comes back as −1.50% ± 0.68%.

Occlusion options on the same wall, in feet (results). Missed is wall that two photos saw but the option doesn't claim.

Option Needs LiDAR False-observed Missed
The app today no 1.1 0.0
Views up to 2 m apart or up to 45° apart no 1.1 0.0
Views at least 5 m apart no 0.0 6.0
Views at least 60° apart no 0.0 8.5
Depth test against true depth, 3 or 9 rows yes 0.0 3.3 (the pilasters)
Depth test, no depth beyond LiDAR's 5 m yes 0.0 8.9
Depth test allowing 0.4 m of wall relief (chosen on this wall) yes 0.1 0.0

View spacing and angle remove the patch only by refusing good wall; a depth test removes it outright.

Field kit. field/FIELD_SHEET.md is a one-page, phone-readable sheet. It fixes the order of taps and measurements, because Measure Lab numbers measurements itself (M1, M2…). The survey and map templates in field/ already name every item, so the team types only tape readings, as the tape shows them. make field converts those readings to feet and fills in the zip's sha256 and session id. It stamps its predictions with the capture they came from, and refuses to score predictions, a map or a survey made for another capture. If the tape reference fails, only the tape row fails.

Why

The placement decision is only as good as the error bound on each measurement, and "unseen is not clear" is only as good as the coverage map. docs/00-overview.md assumes ±0.3 ft of tracking error for an AR tap, the capture plan assumed photo depth could stand in for LiDAR, and the coverage model had never been compared with what the photos actually saw.

Verification

  • make test: 177 tests against hand-computed cases, run by the Evals checks CI job with ruff. They cover drift windows, point-pair errors, triangulation, pose degradation, camera conventions, the coverage eval's frames and cause bookkeeping, field tape parsing and capture and map binding, replay folder naming, cache keys for model runs and triangulation fits, checkpoint verification, Map3D's column tiling, the pinned MARViN manifest, and strict JSON in every committed results file.
  • After the first review round (28119a1), every affected result was regenerated, each step under 1.8 GB. Headlines that moved: one-photo wall p90 (15.1 to 13.6 in), the 5 m depth-test option (7.8 to 8.9 ft missed) and Map3D's facing claim, which now reads 0.50 ft, at the bar (it read 0.52). The 8-photo pose-prior rows and both coverage verdicts did not change.
  • After the second round (c610d10), the triangulation fits were recomputed under their new content keys and reproduced every pose-prior number. Map3D's exact column tiling left its results unchanged. The JSON files now spell a failed percentile as "failed", and the MARViN results come only from the 89 pinned files.
  • The final round (ea4f4bd) needed no result changes. It bounds and confines session zip extraction (plain relative paths only, no duplicates, at most 10,000 files and 2 GiB, 3 GB left free; 6406bef and fce18b8 also refuse an archive over 2 GiB, or a central directory over 20,000 entries or 8 MB, before hashing it or constructing ZipFile, and stream the hash), verifies each checkpoint before any output, pins the Map3D and scoring checkouts by full SHA with checks on reuse, and labels MapAnything rows from their recorded poses.
  • The coverage pass criteria (9a72f06) and the options grid (51e2bfb) were committed before their first runs. A replica of the app's view gates reproduces all 337 of the app's own sightings. The driver's copy of the app's record reproduces the app's answer at 0°.
  • make field-dryrun runs the team's exact command on the templates. All four rows score 9 of 9 in PR Add a scoring harness that compares capture pipelines with a tape survey #4's score, pinned at 77ce830.
  • Evaluation floor: depth rendered from the scan itself is off 0.2 to 0.8 in median. Changing the visibility tolerance (2%, 4%, 8%) moves MoGe-2's medians by at most 0.6 in and its p90s by up to 31% (21.8 in at 2% against 16.6 in at 4%, electro, one photo, 3 to 10 m); that check scores all 8 electro seeds, where the main table scores 7 (sensitivity).

Risk

  • Phones. The drift numbers come from a 2018 phone, and the modern-phone numbers from a reference whose scale is unverified. The field test on the team's phone is the number to trust.
  • ETH3D. Two institutional buildings shot with a DSLR, with the taped distance simulated as exact. The coverage verdict rests on one 19 ft wall seen by 17 photos.
  • Memory. MoGe-2 peaks at 4.07 GB on phone images, so run make field with nothing else heavy on the machine.
  • Dataset cache. Unpacked datasets now need a completion record. Copies unpacked before ea4f4bd have none, so the next make drift or make recon-data downloads them once more (about 0.8 GB for ADVIO and 2.4 GB for ETH3D).
  • Toolchain. Model runs need an Apple-silicon Mac. The coverage and Map3D drivers need macOS 26 and Swift 6.2 (Xcode 26); everything else runs on Linux with uv 0.11 and Python 3.12. METHODS.md, Reproduce, lists the rest.
  • Unpinned fetch. MapAnything and MoGe-2 load DINOv2 code from the main branch of facebookresearch/dinov2 through torch.hub, with weights from dl.fbaipublicfiles.com. Neither is pinned, so a fresh machine may get different code than the cached copy these results used.
  • Field numbering. The P and M numbering comes from reading Measure Lab's code, not from a device run. The first real session should check the M1 banner against the sheet.
  • Licensing. ADVIO (CC BY-NC) and ETH3D (CC BY-NC-SA) are non-commercial and live outside git. They measure accuracy only; no dataset files or images are committed. Checkpoints are MIT or Apache-2.0, pinned by revision and sha256.

Priority: ➖ Normal

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟡 Moderate · up to a491e

Field runs can overwrite another capture’s results, and some accepted images can yield incorrect measurements. Resolve those risks and the remaining evaluation-report issues before merging unless their limitations are explicitly accepted.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to a491e

Downloaded archives are checked against expected sizes and hashes, and the new automated checks have limited permissions. The extraction step does not itself establish that archive contents stay within the dataset directory, leaving a material containment question for people running the evaluations.

Retained concerns

  • Medium · security · inferred: Dataset extraction delegates archive-member containment to the ZIP and 7z libraries rather than enforcing it at the evaluation filesystem boundary. Whether an archive can write outside its destination remains unproven; fixed URLs and pre-extraction digest checks substantially restrict who can supply the archive bytes.
Security review details

Security Blast Radius

  • inferred — If an extraction library permits an unsafe member write, its immediate authority is the filesystem authority of the process running the evaluation, rather than a demonstrated tenant or service identity. The supplied system relationship does not establish server execution.

Security Findings and Attack Paths

  • inferred — Archive member names reach extraction calls without an explicit containment check. Exploitability is unresolved because library handling of those names is unproven here and the configured archives must pass pinned size and digest checks; no arbitrary-file-write finding is established.

Trust Boundaries and Controls

  • observed — The remote-archive boundary checks downloaded bytes before unpacking, while the post-unpack record validates presence and size rather than the location or contents of every filesystem write.

Resilience and Maintainability Implications

  • inferred — A failed or interrupted unpack leaves its completion record absent, which prevents a normal skip on retry, but does not roll back files already written. No concurrent-run ownership contract is established for the shared destination and temporary filename.

Hardening Proposals

  • proposed — Validate each archive member’s normalized destination and file type before extraction, then unpack into an isolated staging directory and publish it only after validation. This would make containment and interruption behavior independent of implicit library guarantees.

…adjacent

Error bars from real data (S1, PR #12): ARKit drift on real outdoor
walks is p90 8.2 in after 3 ft, 22.3 in after 10 ft and 60.1 in after
30 ft (2018 iPhone 6s, ARKit 1.0), so docs/02's flat 0.3 ft holds only
near the meter. Scenes may omit plus_minus_ft (the schema makes it
optional and the app does not export yet), so the defaults matter: an
AR-placed position (tap or vlm object, wall, ground patch) without its
own error now gets its source default plus errors.drift_per_ft (0.16)
per foot walked from the meter. 0.3 ft + 0.16 ft/ft covers S1's p90 at
all three distances. Tape values, the meter anchor and explicit errors
are unchanged. Each candidate is checked with the wall's error at its
far edge from the meter.

Sweep: a run only grows by a start on the same piece within one sweep
step, so it can never claim starts nobody evaluated (S4 case g03 at
44607e0; already split by segment since 58632a1, now explicit).

Speed: the grid puts the battery's centre on the 2 in grid instead of
both edges (still mirror-symmetric, half the starts), and the ground
check measures nearness to other surfaces by distance instead of
buffering per candidate. Example scene about 0.17 s.

Inline comments:
In `@experiments/evals/evals/advio.py`:
- Around line 157-173: Update _read_pose_csv to preserve row alignment by
normalizing non-unit quaternions and retaining their rows, or raise an explicit
error identifying invalid rows instead of filtering them out. Keep the existing
unit-length validation for acceptable rows.

In `@experiments/evals/evals/check_replay.py`:
- Around line 62-92: In check, guard against an empty medians list before
computing aggregates; raise a ValueError stating “no usable pairs” so empty
sessions and pairs skipped by the filters return a clear failure instead of
producing invalid statistics.

In `@experiments/evals/evals/datasets.py`:
- Around line 136-137: Add a finite timeout to the `urllib.request.urlopen` call
in the download flow, and wrap the transfer so any failure removes the `.part`
file before propagating the error. Preserve the existing successful download
behavior.

In `@experiments/evals/evals/field.py`:
- Around line 431-440: Update parse_tape to validate the entire input against
the shape feet [inches] [fraction], allowing a fraction only as the final token
and rejecting any unconsumed or misplaced tokens. Catch ZeroDivisionError
alongside ValueError so a zero denominator is reported as an invalid tape
reading.
- Around line 537-543: Move the ROW_FILES cleanup in score to immediately after
out_dir is established, before unpacking or any operation that can return or
raise; remove the later cleanup so stale row files are cleared on every run.

In `@experiments/evals/evals/map3d.py`:
- Around line 448-450: Update main to verify KIT_CHECKOUT is on the full commit
SHA resolved from KIT_COMMIT and has no relevant uncommitted changes before
calling evaluate; reuse the validation approach in evals.coverage.check_kit
where applicable, while preserving the existing preparation check.

In `@experiments/evals/evals/pairs.py`:
- Around line 100-106: Update the nested pct function to detect whether either
order statistic used by the percentile is the failure sentinel, returning
infinity whenever the percentile includes a failed pair; do not infer failure
from the interpolated value. Preserve linear interpolation and rounding for
percentiles using only finite values, matching the failure behavior of
pooled_percentiles.

In `@experiments/evals/Makefile`:
- Line 76: Update the worktree destination calculation in the SCORING setup so
the documented SCORING=../scoring override does not resolve to the existing
repository root. Keep the destination compatible with the expected worktree
layout so make field can prepare the session.

In `@experiments/evals/README.md`:
- Line 13: Update the data-provenance statement in the README to clarify that
underlying dataset evaluations use real captures, while the pose-prior
evaluation and make field-dryrun use synthetic inputs. Avoid claiming that every
reported number comes from real data.

Security review (session ZIP controlling write paths): fixed in 190ed33. Session and keyframe ids from a session now have to be plain names (letters, digits, ., _, -; never . or ..) before they become the work folder or the upright image names (field.safe_id, tested). ZIP members are extracted by zipfile.extractall, which already drops absolute and .. components. Also in the same commit: the model-runner tests (models/tests) now run with make test and CI.

Before this merges, please cut its write-up to the experiment format in #33 (experiments/README.md). The README should stay under about 200 words: the question and pass criteria, the command, the result with its numbers, and what it changed. Put generated tables in results/ with the command that made them. docs/00 already carries the one-line finding.

- Score every photo count on the same seed groups (comparable_groups), so
  1/2/4/8-photo rows compare like with like. The 8-photo headline rows are
  unchanged; answer 4 now shows more photos make it worse (p90 5.2 to 11.9 in).
- Level the vertical cohort on the ground plane under the cameras, not the
  cameras' mean up (5.4 and 10.0 degrees off); 0.7% and 2.7% of vertical
  points change cohort.
- Weight Map3D boundary columns by their clipped width; the facing claim
  reads 0.50 ft, at the bar, not 0.52.
- Treat a sample with no scan depth as unseen in the truth and reject it in
  the options depth test; add regressions.
- Field kit: keep manifest image paths inside the capture, stamp predictions
  with the capture they came from, refuse a map or truth for another
  capture, and keep the other rows when the tape fails.
- Replay: whole-second bounds and a source stamp before clearing a folder.
- Fingerprint cached model inputs; raise on a truncated PLY header.
- Relabel the walk-to-walk spread as disagreement, not a bound on ARKit error.
- README is now a short front door; methods and results move to METHODS.md,
  with prerequisites (uv, Python 3.12, macOS 26 / Swift 6.2 for the drivers)
  and the unpinned DINOv2 fetch stated as a reproducibility limit.
- Regenerate the affected results.

Repair re-review: seven original threads accepted; three remain open. One additional stale-summary finding follows. Verification used source, committed JSON and lightweight arithmetic, not dataset or model reruns.

Comment thread experiments/evals/METHODS.md Outdated
- Grouped MapAnything: the cache key adds the intrinsics and the checkpoint,
  the runner checks free space and the checkpoint sha256 as models.run does,
  and run.json records the checkpoint.
- The free-space guard measures the volume that holds HF_HOME.
- Pose-prior fit cache: the key adds the bytes of every image and depth map
  the fitter reads. A full refit reproduced every number.
- Map3D claims: 2 cm columns tile each span exactly, including the last
  partial strip, and a claim of exactly 0.5 ft passes. Results unchanged.
- Results JSON is strict: a failed percentile is "failed", nothing to
  compute is null. eth3d_recon.json and pose_priors.json regenerated.
- make field fetches the scoring harness by its full pinned SHA, and stamp
  refuses a map bound to another session before writing anything.
- MARViN: only the 89 files pinned in evals/marvin_manifest.json are fetched
  and scored, each checked against its sha256.
- modern_arkit.md regenerated with the disagreement wording; wall p90
  intervals updated to the regenerated [2.0, 4.6] and [3.7, 6.9].

…pose-noise confound

- run_groups writes each group's depth maps and run.json to a staging
  folder and swaps it in through models.run.publish, so a write failure
  partway through a group leaves the previous outputs and run.json whole.
- METHODS.md section 3 no longer claims (b) is worse with 4 photos on the
  AR-like settings. The 4- and 8-photo groups from one seed get different
  pose noise (one generator shared across sizes) and possibly different
  advio_2018 scales, so those rows mix photo count with pose error. The
  exact-pose comparison (4.5 in with 4 photos, 4.0 in with 8) stands, and so
  does the README's 8-photo wall result. The re-run is issue #159. No
  numbers changed.

RetriggerConfidence Score: 4/5

[Low risk] Adds evaluation framework for computer vision models.

The PR is not ready to merge until the field workflow prevents an unrelated tape survey from being scored against a capture.

Fix All in CodexFindings

  1. P1 Wrong survey passes capture check ▶
  2. P2 Missing groups disappear from scores ▶
Fix with agent prompt
### Issue 1
experiments/evals/evals/field.py:728-731
If an operator passes the wrong tape survey to `make field`, `stamp` adds the current session zip’s hash to that survey without checking which session its readings belong to. The later capture check then passes, and the field report can show a plausible but invalid AR-scale estimate and comparison table. The survey needs an independent session binding before its capture list is updated.

### Issue 2
experiments/evals/evals/recon.py:313-315
When a multi-view model has no output for an eligible seed group, this branch skips the group rather than counting its pairs as failures. Pose-prior scoring does the same. A partial run can therefore report error percentiles based only on groups that produced output, making the fixed-set comparisons look better than they are.

For each issue above, determine whether it is valid and should be fixed. If so, fix it directly.
Summary

Adds reproducible evaluations for AR drift, wall reconstruction, coverage, Map3D and field measurements, with result reports and a Python checks workflow.

  • The field workflow needs an independent binding between a tape survey and its capture.
  • Multi-view scoring should make missing group outputs visible rather than omit them.

The later capture check then passes, and the field report can show a plausible but invalid AR-scale estimate and comparison table. The survey needs an independent session binding before its capture list is updated.

Fixed in f37cddd. The scoring harness rejects unknown survey fields, so a survey can't carry a session id. Its captures list (zip sha256s) is the binding instead: stamp refuses a survey that already lists any other capture, naming it, before it converts or appends anything or writes the map. A survey stamped for this capture is accepted again. Test: test_stamp_refuses_a_survey_already_bound_to_another_capture checks that the survey file is unchanged and no stamped map is written. Survey readings carry no per-reading session id to compare.

…ind the survey

- coverage_options: an option that claims no wall is untested, not passed,
  as in evals.coverage. The five 75-degree grid rows go from passes: true to
  null, and their table cells read "untested". Nothing else changed.
- recon and pose_priors scoring refuse a method whose output covers some of
  a size's seed groups but not all, naming the missing groups; a size with
  no output at all is still left out as never run. Both scorers reran with
  this check and reproduced their committed results byte-for-byte, so none
  came from a partial run.
- stamp refuses a survey that already lists another capture, before writing
  anything. The harness's survey format has no session field, so the
  captures list is the binding.

Use a turning path to test the mirrored-world case.

The fixture uses a straight path and one constant camera heading. Both reflection candidates can therefore have zero heading-offset spread, while the final rotation can still align a straight path. A regression that selects the unflipped candidate can pass this test. Add a change of direction and assert that the returned positions use the intended reflection.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Mark intervals with insufficient independent samples as unavailable.

bootstrap_interval resamples groups and noise draws. With one group and one draw, every replicate contains the same result, so interval_95 equals the point estimate. This does not estimate uncertainty across groups or draws.

Emit an explicit unavailable value for this case, update the formatter to display it as unavailable, and regenerate the results.
