Requirements +below are ordered along that chain. + +## AR-001 … AR-003 — Face detection + +Detect faces in sampled video frames. + +- Detector runs on frames sampled at `sample_fps`, not every decoded frame. + The default (1.0) originates from I-frame decode speed, not from an accuracy + requirement — it is a **cost knob and may be adjusted**. Under scene-scoped + presence (SR-002) a lower rate still answers the question, but it lengthens the + interval between samples and so weakens IoU-based association; sweep the two + together (VR-002). +- **Minimum face size is 40×40 px**, expressed in **original video resolution**, + not decoded-frame pixels. Stating it in original space decouples it from + `dense_scale`: otherwise a 0.5 downscale silently doubles the effective + threshold, and dense mode is exactly what scene detection uses. + + 40 is **measured, not estimated** — it replaces an earlier 66 px guess. Two + studies bracket it, and the difference between them is the whole reason the + number is 40 rather than 32: + + - **VR-005** degrades an already-aligned 112×112 crop and matches it against + a native-resolution gallery. Alignment is held perfect, so it isolates the + *embedder*: the knee sits at 24–32 px, and 32 px still returns 98.1% TPI. + - **VR-013** downscales the **whole frame before the detector**, so detection + and landmark regression degrade along with it. End to end, holding 90% of + the plateau needs roughly **50 px**, against VR-005's ~22 px. + + The gap is detection and landmark error, which VR-005 excludes by construction + — so VR-005 is an **upper bound on quality**, not a threshold, and reading a + floor off it would admit faces in the falling region. **AR-002 therefore takes + VR-013's number.** 40 sits below the 50 px plateau deliberately: FPI is 0.0% at + every scale in both studies, so resolution loss costs recall and never + precision, and an over-tight floor discards presence that SR-002 requires. +- Emits bounding box, detector confidence, and 5-point landmarks. +- Bounding boxes must be reported in **original video pixel space**. When + `dense_scale < 1` downscales the decoded frame, coordinates are rescaled by + `bbox_upscale` before leaving the pipeline. +- **No fixed cap on faces per frame.** `max_faces` (10, largest-first) is removed + so crowded scenes do not systematically lose their background cast — which + X-Ray credits as scene members (SR-002). See the backpressure requirement below; + the cap is currently the only thing bounding per-frame cost, so it cannot be + removed on its own. + +**Current:** SCRFD-500MF via `face_detector_node.hpp`, thresholds in `config.hpp` +(`detector_conf` 0.5, `detector_nms` 0.4), `min_face_px` 40, `max_faces` 10. + +**Gap:** `min_face_px` re-expressed in original resolution — the value 40 is +already correct after VR-013, so what remains is the space it is measured in, not +the number; `max_faces` +removed, gated on backpressure (AR-004). + +## AR-004 — Backpressure + +Removing the per-frame face cap makes the number of faces entering the pipeline +unbounded and content-dependent — a crowd scene can produce an order of magnitude +more than a dialogue scene. The network must absorb that by **slowing down**, not +by dropping work or growing without limit. + +- The embedder is the bottleneck and must exert backpressure upstream: when its + input is saturated, the detector and decoder block rather than queue. +- Channel capacities are currently fixed at 16 (`main.cpp:204-207`) and were + chosen against a bounded ≤10 faces/frame. They must be re-derived, and + overflow must block rather than throw. +- `kMaxFaces` in `identity_matcher_node.hpp:133` **throws** when exceeded. With no + cap upstream that becomes a crash on crowd scenes; it has to go or become a + batching bound rather than an error. +- Memory is the real limit: faces carry 112×112 crops plus 512-float embeddings. + Backpressure must engage on bytes in flight, not just item counts. + +### The fix is not in this repo + +**Every node output in KPN uses the dropping `push()`** (`pool_node.hpp:404`, +`:710`; also `branch.hpp`, `fanout.hpp`, `interrupt_node.hpp`). A lossless +`push_blocking()` — "wait for the consumer to drain instead of dropping; the +producer just runs slower" — already exists on both `Channel` +(`channel.hpp:144`) and `OutputPort` (`variant_node.hpp:81`), **and nothing +calls it.** + +So AR-004 is a change to the KPN repository, not to this one. It needs either a +per-channel lossless policy or a network-wide default, and this pipeline should +select lossless: a dropped frame here does not degrade a result, it silently +changes one. + +**Measured, not inferred.** One 77 s clip at 5 fps should yield ~385 sampled +frames. On CPU it produced 49, ending at 51 s, with 285 frames dropped at +`camera_pos` and 51 at `face_aligner`. Rebuilt with CUDA the same clip ran in +29 s and reached EOF correctly — and still dropped **320** frames at +`camera_pos`, yielding 65. Faster hardware moves where the queue backs up; it +does not change what happens when it does. + +Two consequences worth stating: + +- **Raising channel capacity is a stopgap, not a fix.** It lowers the + probability of overflow without changing the behaviour on overflow, and the + failure it hides is silent corruption of the output. +- **Fixture generation is blocked on this** (VR-001), because what gets dropped + depends on timing. The same command run twice can produce different dumps, and + a golden fixture cannot be built on that. + +**Current:** fixed in KPN. Node data outputs *park* on a full channel — the +value is held in a one-slot buffer, the worker is released, and the channel's +space callback resubmits the node once the consumer drains. That replaced +`push_blocking`, which slept inside the push and, with one thread per node, +stopped that node draining its own input. Sentinels remain out-of-band so EOF +can always overtake a stalled data path. Verified on the same clip: 385 of 385 +sampled frames written, zero drops, and two consecutive runs byte-identical +where previously they were not. + +A later audit found the losslessness was still incomplete in three places, all +now closed and each pinned by a regression case in the KPN suite: + +- **`FilterNode` and `RouterNode`** were the last data paths still using the + throwing `push()` with the exception swallowed. A full output discarded the + value, and that included the **EOF sentinel**. The decimator passes EOF by + predicate but its output is reliably full — the embedder is the slowest node + in the chain — so the token was discarded, nothing downstream shut down, and + the run had to be killed. This was the wedge. +- **The sentinel could arrive ahead of a value still queued behind it.** `pop()` + observed the ring empty and then took the sentinel; a producer can push a + value *and* publish the sentinel inside that window, so a consumer treating + EOF as a hard stop loses the tail. +- **Two firings of one node could overlap**, because the submit gate was + released before the firing had finished with the node's state. That breaks the + one-slot park itself: a parked value can be overwritten by the other firing, + with no drop recorded anywhere. + +**New constraint:** a channel carries at most one undelivered sentinel. A second +offered before the first is taken is refused and reported, never queued and +never overwritten — two control tokens on one channel means the stream ended +twice. Single-shot EOF is what everything does today; this becomes live the +moment a pipeline is reused for a second input. + +**Consequence:** a lossless decimator is a backpressure point, not a relief +valve. The source now throttles to the face branch rather than quietly thinning +it. That is what this requirement asks for, but it changes the shape of a loaded +run and has not yet been benchmarked. + +It also ran *faster* (29 s → 17 s). A dropped frame has already cost its decode, +and the overflow exception cost more — so the lossy path was paying for work it +then discarded. + +**Gap:** the remaining half — bounding by **bytes in flight** rather than item +count. Channel capacity is still a count of items, and a face carries a 112×112 +crop plus a 512-float embedding, so a crowded frame occupies far more memory per +slot than a sparse one. That matters once `max_faces` is removed (AR-003). + +## AR-005 — Face alignment and crop + +Produce the exact input ArcFace expects. + +- 112×112 BGR crop via the standard ArcFace 5-point similarity transform. +- Landmark order must match the SCRFD/ArcFace convention (left eye, right eye, + nose, left mouth, right mouth). +- Alignment is the *only* geometric normalisation; no additional augmentation at + inference. +- **The transform is fitted by Umeyama's closed-form least squares over all five + points**, which is what InsightFace uses (skimage's `SimilarityTransform` *is* + `_umeyama`) and therefore what produced the crops ArcFace and LVFace were + trained on. The canonical warp is part of the input distribution, not an + implementation detail (AR-011). +- **Not a robust estimator.** A RANSAC fit buys a small residual by discarding + the landmarks that disagree with the model, and on a turned face those are the + foreshortened ones — the signal AR-030 reads. With five points and a two-point + minimal sample it also cannot separate a mis-detected landmark from honest + out-of-plane rotation, so the robustness is nominal while the cost to AR-030 is + total. It is RNG-driven besides, which made replay determinism a property of + thread scheduling. + +**Current:** `align_face()` in `src/face_utils.hpp`, Umeyama fit via +`umeyama_similarity()`, `cv::warpAffine` to `{112, 112}`. **Gap:** none. + +> **Migration note — this was a defect, not a refinement.** Until this landed the +> fit was `cv::estimateAffinePartial2D(…, cv::RANSAC, 3.0)`. The expectation was +> that the two agree wherever RANSAC keeps all five points, leaving a small +> divergence on non-frontal faces. **Measured, that is wrong.** On 400 random +> gallery headshots, one model held fixed and only the estimator varied: +> +> | | median | p90 | max | +> |---|---|---|---| +> | Crop disagreement (source px, over the crop corners) | 16.97 | 75.91 | 223.31 | +> | `cos(umeyama, ransac)` for the resulting embedding | 0.791 | — | — | +> +> 83.5 % of crops embed to a cosine below 0.99 of their Umeyama counterpart — +> they are not the same face crop. The mechanism is that a 4-DoF similarity is +> exactly determined by **two** points, so every minimal RANSAC sample fits its +> own pair perfectly and is then scored on the other three. Real landmarks sit a +> median 2.74 canonical px from any similarity fit to the template (see AR-030 +> below), so images with a landmark outside the 3 px band are the common case, +> not the exception; RANSAC then keeps two or three inliers and returns a wildly +> under-determined transform. +> +> **Every gallery baked before this change must be rebuilt** — GR-004's embedder +> stamp catches a model change, not an aligner change, so nothing else would say +> so. +> +> **How much this cost in accuracy is a separate question, and the answer appears +> to be: less than the crop numbers suggest.** Rebuilding the full gallery +> (2456 actors) moved the intra/inter separation the AR-023 calibration is fitted +> from only slightly: +> +> | | intra-actor | inter-actor | separation | +> |---|---|---|---| +> | RANSAC | 0.6234 | 0.0407 | 0.5827 | +> | Umeyama | 0.6340 | 0.0440 | 0.5900 | +> +> The reconciliation is that the old warp was *wrong but self-consistent*: it +> produced a differently-framed face rather than a scrambled one, gallery and +> probe went through the same estimator, and the embedder tolerates framing +> variation. So the figures in `model-bakeoff.md`, `best-model.md` and +> `pose-expansion.md` were all produced through the broken warp on both sides and +> should be re-run, but there is no measured basis for expecting them to move far. +> +> The sharper evidence of the old instability is duplicate detection: rebuilding +> with an unchanged `dedup_tol` dropped **1614** near-duplicate images, where the +> original build dropped on the order of a hundred.

Every downstream threshold assumes unit norm. +- Faces are embedded in batches of at most `embed_batch_size` to bound + per-call latency. +- The embedding model is a build-time choice; the gallery must have been built + with the *same* model (see GR-004). + +**Current:** `embedder_node.hpp` + `face_embedder_engine.hpp`; default +LVFace-B_Glint360K. **Gap:** none. + +## AR-028 … AR-030 — Embedding input quality + +An embedder handed a face it cannot represent does not fail. It returns a +confident, plausible, wrong vector, and that vector then competes on equal terms +with every good one in the gallery — the same failure mode AR-011 names for +whole models, occurring here at the level of a single region. Quality assessment +is how that is caught **at inference**, rather than inferred afterwards from a +study of why a film scored badly. + +Three axes, assessed on every face before its embedding is used as identity +evidence. They are kept separate and **not collapsed into one scalar**: they fail +for different reasons, have different remedies, and — as below — do not even earn +the same response. + +- **Size** — already AR-002, floor at 40×40 px in original resolution, measured + end to end by VR-013. It is the precedent for the other two: the + threshold was *located*, not chosen. +- **Sharpness** — motion blur and soft focus destroy the high-frequency detail + the embedder keys on, and unlike size they leave the bounding box looking + perfectly healthy. Measured on the **112×112 aligned crop**, not the raw box: + the crop is already scale-normalised, so a measure taken there cannot silently + re-measure face size and double-count it against AR-002. + + The measure is the **variance of the Laplacian divided by the variance of the + crop** — `crop_sharpness()`, dimensionless. The division is the part that + earns its place: a raw Laplacian variance, the textbook measure, scales with + the square of image contrast, so a dim scene reads as soft and a graded-up one + as sharp, and VR-012 would locate a different knee in every film. That is + AR-024's objection to the raw cosine in another metric. Normalised, the axis + means the same thing everywhere, which is the precondition for a single knee + existing at all. + + Read spectrally it is `E[|ω|⁴]` under the crop's own energy distribution, so + the blur ladder is monotone by construction rather than by fitting: Gaussian + blur multiplies that distribution by `e^{-σ²|ω|²}`, which can only move mass + downward. Two consequences follow from the same identity and are recorded on + the function: it needs the low-frequency mass real images have (on a + flat-spectrum synthetic an anisotropic smear makes it *rise*, because the + surviving perpendicular detail really is as fine as before), and it conflates + focus with intrinsic texture, so a bearded face outscores a smooth one at equal + focus. Both are true of every no-reference sharpness measure, and both are + reasons AR-028 carries the number rather than thresholding on it. +- **Visibility** — extreme pose or occlusion means the face presents fewer of the + features the embedding assumes are present. The measure is the **residual of + the AR-005 alignment fit**: the RMS landmark error, in canonical 112×112 + pixels, left over after the best similarity transform onto the ArcFace + template. It costs nothing — the transform is computed for the warp regardless, + and the residual is what that fit could not explain. + + Two properties earn it the job over an explicit yaw estimate: + + - A similarity absorbs rotation, uniform scale and translation **exactly**, + so the residual is by construction the non-similarity part of the + deformation: out-of-plane rotation and foreshortening. In-plane roll + contributes nothing, so "a tilted head reads as a turned one" is excluded + structurally rather than by tuning. The destination frame is fixed, so face + size cannot leak in either — that is AR-002's axis, and double-counting it + would make a small frontal face look occluded. + - It responds to **occlusion** and to plainly broken landmark sets, which an + angle regressor by construction does not: a hand across the face is not a + rotation, but it does displace landmarks. + + Indicative magnitudes from a synthetic foreshortening sweep (`k ≈ cos yaw`): + `k=1.0 → 0.00`, `0.9 → 1.18`, `0.75 → 3.11`, `0.5 → 6.72`, `0.3 → 9.85` + canonical px. Smooth and monotone with a usable range; the mapping onto real + faces is VR-012's to establish, and no threshold is set from these numbers. + + **The synthetic ladder is noise-free and therefore optimistic about the low + end.** Measured on 400 real TMDB/Jellyfin headshots — the most frontal, most + cooperative population the pipeline ever sees — the residual runs p5 1.11, + median 2.74, p90 4.82, max 6.35 canonical px. So landmark noise alone occupies + roughly the first 3 px, and the synthetic sweep's "26° yaw ≈ 1.2 px" sits + *below* the noise floor on real data. VR-012 must set any threshold against + this measured distribution, and a discount curve has to treat the first few + pixels as uninformative rather than as mild pose. + + Neither a dedicated landmark model (`models/2d106det.onnx` is present but + referenced nowhere — and it emits points, not pose) nor a direct pose CNN is + adopted unless VR-012 shows the residual insufficient. If one is needed the + candidate is **6DRepNet** (MIT, RepVGG-B1g2, 3.47° MAE on AFLW2000) rather than + Hopenet, which it dominates on accuracy, licence, recency and export + friendliness. Two caveats to record before that happens: both are trained on + **300W-LP**, which inherits research-only terms from 300W's constituent sets, + and both want their own loosely-framed ROI rather than the ArcFace crop — a + second warp and a second image in flight, which lands on AR-004's byte-based + backpressure gap. It would also have to run **per track** — over the bounded + view set AR-019's diversity buffer already keeps — not per face per frame, + which is the cost rule applied as written: fewer regions, never a degraded + input. + +**Failing an axis discounts the observation; it does not delete the detection.** +Only size drops the face outright, and only because VR-005 measured a knee below +which the embedding carries no signal to discount. Blur and pose are different: + +- A blurred or turned face is still evidence of **presence**, which is what + SR-002 actually asks about. +- The tracker admits a link on position *or* identity precisely so that a face + "whose embedding degraded (blur, profile turn)" stays linkable. Remove the + detection and the track fragments, costing the window extent AR-012/AR-013 + exist to protect. +- AR-019 harvests non-frontal views *because* TMDB headshots are frontal. + Discarding turned faces starves the mechanism built to fix the pose problem of + its raw material, and AR-020 then has nothing to resolve at EOF. + +The natural home for the discount is `EvidenceDiscounter` (AR-025), which already +weights how far one observation may move a track's belief. Note that its present +weight is pure *novelty*, so a profile view — maximally distant from everything +counted so far — currently scores near 1.0 and moves the belief hardest, when +against a frontal gallery it deserves the least trust. Novelty and reliability +are orthogonal and multiply; quality supplies the second term. + +**Quality is carried, not consumed.** The vector travels with the face and is +written to the VR-001 dump alongside the embedding, so a threshold can be +re-litigated against recorded data instead of by re-running video, and so +VR-010's provenance records what the run actually admitted. + +**No quality threshold is hand-set.** Each axis either has a measured knee +(VR-012, as VR-005 did for size) or it discounts rather than drops — a +hand-chosen cutoff on an uncalibrated measure is the same unfalsifiable magic +number AR-024 retired for similarity, and it would fail the same way: meaning +something different for every detector, every embedder and every film. + +**Current:** all three axes are measured and carried, and the vector reaches the +dump. `FaceAlignerFunc` is where it is filled in, because both measured axes fall +out of work the warp already does: visibility is the residual from +`estimate_alignment()`, and sharpness is `crop_sharpness()` on the 112×112 crop +the node has just produced. Size stays `bbox` — deliberately not copied into a +field of its own, since that would hold the same quantity in two coordinate +spaces and the copy is the one that drifts. No face is admitted unscored, so a +negative value downstream is a bug rather than a poor-quality face. The +degenerate-fit case is still dropped — it has no crop and no fit to score — but +is now **counted** and reported once at EOF instead of vanishing. + +`sharpness` and `alignment_residual` are written to the VR-001 dump as per-face +columns parallel to `confidence`, taking the dump to `schema_version` 2. The bump +is not for readers — both sides check by name, and a v1 dump still replays — but +so that a consumer of the vector can tell *never scored* from *scored zero*, +which is a real reading on this axis. Nothing yet *consumes* any of it. + +**Gap:** three, in the order they block each other. + +1. **The fixtures do not carry the vector.** They are v1, and re-dumping needs a + GPU host (`scripts/make_fixtures.sh`), so until that runs VR-012 has recorded + data available in principle and none in hand. +2. **AR-030's discount does not exist.** The measure must reach + `EvidenceDiscounter` as the reliability term, multiplying the novelty weight + rather than replacing it. +3. **Two properties of the sharpness measure are recorded but unquantified on + real faces**, and both distort the low end of the axis, which is where a knee + would go. It is exactly contrast-invariant in the algebra, but the 8-bit + quantisation floor lands in the numerator, so a crop that is *dim and soft* + reads sharper than it is — on the synthetic ladder a half-contrast copy reads + 0.9% high when sharp and 148% high at σ 2.5. Separately, `align_face` warps + with `BORDER_CONSTANT`, so a face crossing the frame edge brings a hard black + step into the crop, and a step edge is high-frequency; the normalisation + blunts this but does not remove it. Neither is corrected here. The candidate + fixes are a validity mask or a different border mode, and the second changes + what the embedder is fed (AR-011) — so VR-012 measures the size of each effect + on the dumped distribution first, and no correction is chosen before that. + +## AR-007, AR-008 — Tracking + +Link detections across frames into tracks representing one physical person. + +Association cost combines three signals: + +- **Spatial** — IoU between the candidate detection and the track's last box. + Meaningful only for tracks seen in the immediately preceding frame. +- **Appearance** — similarity to the track's running directional mean embedding + (averaged, then re-normalised to the unit sphere), **expressed as a + probability** (AR-024), never as a raw cosine. +- **Weighting** — `track_alpha` interpolates the two, and is **frame-dependent**: + on `is_cut` / `is_scene_boundary` (AR-009, AR-010) it drops toward embedding-only, because + position carries no information across a viewpoint change. + +**There is no separate re-acquisition mechanism.** A track whose face is lost sets +`last_seen` and stays a candidate for association until extinction; matching it to +a later detection is ordinary inter-frame tracking, not a distinct revival path. +The property falls out of the embedding comparison the tracker already does. + +Consequences: + +- **One candidate pool**, not an active set plus a parked set. `last_seen` alone + distinguishes them, and it only affects whether IoU means anything — dormant + tracks are matched on embedding, since time has passed and position is stale. +- The current cross-cut park/revive path (`cut_revive_sim`, + `cut_inactive_max_frames`) is this same mechanism special-cased to cuts. It + collapses into the general path. +- A track dies only by extinction: `last_seen` set for longer than the timeout. + +**Current:** `face_tracker_node.hpp` maintains separate `tracks_`/`inactive_` +maps with distinct thresholds and a revival branch. **Gap:** unify into one pool +keyed on `last_seen`; make `track_alpha` frame-dependent; move association into +probability space (AR-024). + +## AR-009 … AR-011 — Cut and scene-boundary detection + +Two distinct signals, deliberately kept separate: + +- **`is_cut`** — always on. Grayscale histogram correlation below + `cut_threshold` flags an *intra-scene camera-angle change* (shot/reverse-shot). +- **`is_scene_boundary`** — opt-in (`--scene-detect`). TransNetV2 over a densely + decoded, downscaled stream flags a *true shot/scene boundary*. + +> **`is_scene_boundary` currently has no producer.** `grep -rn is_scene_boundary +> src/` finds no assignment anywhere: `SceneDetectorFunc` is a *terminal sink* +> (`main.cpp:298-300`, `kpn::out<>`) that writes `scenes.json` and never +> annotates the `Frame` flowing to the face pipeline.

A model run off-distribution produces +confident, plausible, wrong output, and the error is invisible without a study +that should not have been necessary. + +Two places this was violated, both now closed: + +1. **`scene_decode_fps = 12` starved TransNetV2.** `kWindow` is 100 frames. At + native 25 fps that window spans ~4 s; at 12 fps it spanned ~8.3 s, so the + model saw roughly half-speed motion over twice the temporal context it was + trained on. **Requirement: feed TransNetV2 at the source's native frame + rate**, so a 100-frame window covers the duration the model expects. The + "tolerates ~12fps" note in `config.hpp` described a compromise, and the + recorded margin was consistent with it — a non-boundary baseline at ~0.50 with + real boundaries reaching only ~0.7+ is a compressed separation, not a healthy + one. **Done:** `scene_decode_fps` defaults to 0. + +2. **Hardcoded 25 fps in boundary dedup.** The node merged boundaries closer than + `0.04 s` — "~1 frame @25fps". **Requirement: derive this from the source's + actual frame rate. Done:** `SceneDetectorFunc::dedup_window_sec()` takes the + median of the frame intervals the detector was actually fed and halves it. + Half a frame rather than a whole one, because the only thing being merged is + one frame scored by two overlapping windows; two distinct frames are a full + interval apart and both have to survive. + +The two are one change, not two. A native-rate stream is where the old constant +did the most damage — at 30 fps, 0.04 s is wider than a frame, so two cuts on +consecutive frames merged into one and the loss showed up nowhere: the file +simply had fewer boundaries. + +Dense decode is the pipeline's cost driver, so (1) is not free. The cost is +accepted: the alternative is a boundary signal that steers association (AR-007) while +being quietly unreliable. `dense_scale` remains available as a spatial reduction, +since downscaling is a documented, understood degradation rather than a temporal +one the model has no defence against — and TransNetV2 downsamples to 48×27 +regardless. + +**Current:** histogram cut in the decoder; `scene_detector_node.hpp` for +TransNetV2, fed at native rate with a framerate-derived dedup window. +**Gap:** `scene_threshold` (0.60) is still the value picked against 12 fps input +and is now certainly wrong — VR-006 re-fits it, and until it does, boundary +recall at native rate is untuned rather than better. `--scene-detect` is +default-off despite now feeding association. + +## AR-012 … AR-017 — Track-level identity propagation — **CHANGED BEHAVIOUR** + +> **Requirement:** when a face is identified, it is considered identified for the +> **entire track**. + +A track is one physical person by construction (AR-007), so an identification +anywhere on the track is evidence about all of it. Presence windows must +therefore be derived from **track extents**, not from the subset of frames that +happened to match. + +Required semantics: + +- A track is **owned** by actor A once the accumulated posterior for A exceeds + the ownership threshold (AR-025). This is a Bayesian accumulation over the track's + frames, not a count of accepted frames — so a single decisive observation and a + long run of marginal ones are distinguished rather than conflated. +- Once owned, the actor is present for the track's **full extent** — + `[first_seen, last_seen]`, including frames where the face was turned, + occluded, or simply scored below threshold. +- **A track with no owner emits nothing.** No posterior crossed, so there is no + claim to make. Such tracks are captured for diagnosis (AR-022) but do not appear in + output. See "Unidentified presence" below. +- **Every presence claim carries its belief.** The accumulated posterior that + justified the claim travels with it — through the aggregator, into the truth + file (IR-001), and onward. Confidence is not a serialisation concern bolted on at + the boundary; the pipeline computes belief for every decision it makes (AR-025), so + discarding it and emitting a bare interval throws away information that was + free. + + A claim also carries **how it was identified** — live, deferred (AR-020), or + pooled from a cluster (AR-021) — because those routes rely on different evidence. + A deferred identification leans on harvested references rather than baked ones; + a pooled one aggregates across tracks. The posterior already reflects the + strength of each, but the provenance tells a consumer *why*, and tells us which + route is producing errors when one is. + +### Belief swap terminates the track + +If a track is owned by A and the accumulated belief subsequently swaps to a +different actor B, **the track is terminated and a new one started for B**. The +old track closes normally at its `last_seen`; the new track begins at the frame +where the swap occurred. + +The rationale is that a swap is not a correction — it is almost certainly a +**missed camera or scene change**, where the tracker carried one `track_id` +across a viewpoint change and began following a different person. Two genuinely +different individuals both accumulating a threshold-crossing posterior on the +same face is not realistic short of identical twins; a `track_id` spanning two +people is. + +Treating it as a swap-and-continue would emit one window blending two people. +Treating it as a track boundary yields two windows that are each correct. + +Ownership is therefore **established at first crossing, not deferred to track +death** — the first crossing is a real claim about the frames seen so far, and a +later contradiction ends that claim rather than revising it. + +### Simultaneous ownership + +If two actors cross the threshold on one track at effectively the same time, the +**highest posterior wins**. This should be rare — the swap rule above catches the +common form of the problem — and it must be counted and reported (GR-003) as a +track-ID collision indicator. + +### Identity contradiction is a cut detector + +If **two live tracks are both owned by the same actor**, at least one is wrong: a +person cannot be in two places at once. The cause is the same as the belief swap +— a missed camera or scene change that split one person into two tracks, or +attached an identity to the wrong one. + +**Requirement: treat this as a detected cut.** Reset the affected tracking state +and re-associate on embedding, exactly as an `is_cut` signal would (AR-007, AR-009). + +This gives a third cut-detection signal, derived from *identity* rather than +pixels, and it fires precisely where the pixel-based detectors failed — a cut +subtle enough for the histogram and TransNetV2 to miss is not necessarily subtle +in identity space. It is also self-correcting rather than diagnostic: the +contradiction is detectable **online**, the moment both tracks hold the belief, +not at output time. + +A consequence worth noting: with this in place, overlapping windows for one actor +should be rare rather than routine, because the condition that produces them is +now caught and repaired while tracking. Any that survive to output indicate the +repair failed and should be counted. + +### Unidentified presence — TBD + +A track that is never owned is still *someone* on screen. Emitting it as +anonymous presence would let a consumer show "unidentified person", and would +give the human-in-the-loop association tool ([`../../SPEC.md`](../../SPEC.md) §4) +its work queue directly. Combined with the context crops of AR-022, it may also be +the path to recognising extras and background cast the gallery has no entry for. + +**This is deliberately undecided.** It changes the truth format and invites +consumers to display something that may not be useful. Recorded here so the +option is not lost; not specified until the AR-022 debug output shows whether these +tracks are worth surfacing. + +**Current:** presence is built from *per-frame accepted detections only*. +`identity_matcher_node.hpp:145-231` decides acceptance independently per face per +frame; `result_sink_node.hpp:123-129` collects the timestamps of accepted frames; +`result_sink_node.hpp:139-147` sets `win_start = ts_vec[0]`, the first accepted +timestamp. `track_id` is carried on `IdentifiedActor` but is used only for debug +output — it never gates or backfills a window. A window therefore starts when the +actor was first *recognised*, not when their track began. + +**Gap — this is the main behavioural change in this spec.** + +Design is settled in [`plan.md`](plan.md) under AR-012/AR-013: a +`TrackRegistry`, held by `shared_ptr` and used by `FaceTrackerFunc` as its state, +where each track carries `first_seen` plus an **optional `last_seen`** — unset +while on screen, set to the last on-screen timestamp when the face is lost, unset +again when a later detection associates to it. A track whose `last_seen` exceeds +the extinction timeout is reaped and **pushed to the result aggregator** as one +finished claim: *this actor was on screen from a to b*. + +Consequences: + +1. The tracker's `tracks_`/`inactive_` maps become one track set, distinguished + only by whether `last_seen` is set; there is no separate revival path (AR-007). +2. Closing a track *is* the presence assertion — emitted once, complete, never + revised. No later reconciliation stage exists. +3. **`anneal_sec` and `extinction_sec` are deleted, not re-tuned.** Both exist + only to bridge gaps between isolated accepted frames; a track that survives + its own gaps leaves them nothing to do. `SceneTrackerFunc` goes with them. + What remains to tune is the **ownership posterior threshold**, the + **correlated-frame discount** (AR-025), and the **extinction timeout**. +4. Every track must be closed at EOF. A film ends with faces on screen and those + tracks have not timed out, so without an explicit flush the closing scene's + actors are never emitted — a silent presence loss that looks like a + recognition miss. +5. Zero-length windows (`start == end`, a single-frame track) remain possible; + the truth format permits them, and `build_xray()` floors/ceils into integer + seconds. +6. **Pull it out by the roots — including the published field.** `anneal_sec` is + not just a constant: it appears in the truth schema + ([`jRay/SPEC.md`](../../jRay/SPEC.md)), in the Jmanifest format and in the + server's storage columns + ([`JRay-public-server/SPEC.md`](../../JRay-public-server/SPEC.md)). Retaining + it as a vestigial `0` would be worse than removing it: a field that names a + mechanism no longer in the pipeline is actively misleading to anyone reading a + manifest, and it would outlive everyone who remembers why it is zero. It goes + from all three repos under one coordinated `schema_version` bump — the same + bump IR-004 already requires, so there is exactly one breaking change, not two. + + Removal list: `Config::anneal_sec`, `Config::extinction_sec`, + `SceneTrackerFunc` and its node wiring, the sink's annealing pass + (`result_sink_node.hpp:139-147`), the truth-file field, the Jmanifest field, + the server column, and the optimizer's parameter entries. Grep for both names + and expect no survivors. + +## AR-018 … AR-021 — Per-film gallery expansion and deferred identification + +Three requirements that only make sense together, so they are specified together. + +### The problem being solved + +**TMDB headshots are overwhelmingly frontal.** Films are not. An actor is +recognised easily in the shots that resemble a publicity still and missed in +profile, three-quarter, low-angle, poorly lit, or partially occluded views — even +though those are most of their screen time. + +So the pipeline's failures are dominated by **pose**, not by identity: the same +person the gallery knows, at an angle it does not. Both mechanisms below exploit +that. + +### AR-018 — Per-subject embedding store + +Every track maintains a running store of its own embeddings, **identified or +not** — the structure is the same for both. + +An embedding is admitted only if its similarity to one already in the store falls +**inside a band**: + +- **Upper bound** — too similar and it is redundant, teaching nothing the store + already covers. +- **Lower bound** — too dissimilar and it may not be the same person at all; + admitting it risks poisoning the store. + +A starting band of roughly **0.90–0.95** is the working estimate, to be tuned +(VR-007). Note this is deliberately conservative compared to the retired +`expand_novelty_sim` (0.55), which promoted embeddings *far* from the gallery — +much more aggressive, and much more exposed to admitting the wrong person. + +Both bounds must be expressed as calibrated probabilities, not raw cosines (AR-024). + +The lower bound is asked twice. `admit` compares a newcomer against its +*closest* existing member, which a gradually drifting track can chain past: every +step inside the band while the endpoints are strangers — the shape a track-ID +collision takes over a slow pan. So the same bound is re-applied across **every +pair** in the store before promotion. One bound, two enforcement points; not a +second constant. + +Novelty is deliberately **not** a threshold. The store's eviction policy orders +its members by similarity to the actor's existing references and drops the +best-recognised one, so novelty-seeking is a ranking with nothing to tune, and +the band's upper bound already refuses the redundant views at the door. + +**Current:** implemented in `gallery/track_gallery.hpp` — `admit` at the door, +`store_coherence` at promotion, both bounds from `Config::expand_band_lo/hi`. +Refusals are counted (`band_rejected`). + +**Gap:** the bounds themselves are unswept working values (VR-007). + +### AR-019 — Expansion of known actors + +When a track is owned (AR-012), its store is promoted into a **per-film, in-memory +annex** for that actor, folded into best-of-N scoring alongside the baked +references. The annex does not persist. + +Promotion requires **certainty that the span is one person**: + +- the track is owned, with the belief stable (no swap, AR-012); +- no camera cut, scene boundary, or identity contradiction occurred within the + span (AR-009, AR-010, AR-015) — all three signals must be quiet, not just the histogram cut as + today; +- the band of AR-018 is satisfied. + +The purpose is precisely to acquire the **non-frontal views TMDB lacks**, at a +confidence the gallery alone cannot supply. + +### AR-020 — Deferred re-identification of unknown tracks + +**This is what the expansion is for.** + +- An unowned track, on extinction, is **not discarded**. Its embedding store, + metadata and context crops (AR-022) move to a **to-be-identified (TBI) queue**. +- At **end of playback**, TBI entries are pooled (AR-021) and re-assessed against + the *final* expanded gallery — which by then holds the pose-varied views + harvested from the whole film. +- Entries that now cross the ownership threshold emit presence windows exactly as + a normally-owned track would. Entries that still do not are the output of AR-022, + and the work queue for human association + ([`../../SPEC.md`](../../SPEC.md) §4). + +The asymmetry this exploits: an actor confirmed frontally early in a film +contributes profile views to the annex, and a profile-shot track that failed at +minute 12 matches once the film is over. Ordering ceases to matter. + +**This is cheap.** Embeddings are already computed; re-assessment is matching +against an in-memory annex — no decode, no detection, no embedding. The cost is +retaining unowned track stores until EOF. + +### AR-021 — Pool unknown tracks before matching + +Re-assessing each unknown track alone wastes the strongest evidence available. +A single track is short and pose-poor; the *same unknown person* usually appears +across many tracks throughout the film. + +**Requirement: cluster the unknown tracks, treat each cluster as one identity, +and match the pooled cluster against the full gallery.** + +Each unknown track's store is effectively a small gallery of one unnamed person. +Clustering merges the ones that are the same person, and the pooled result is a +far richer representation — many poses, lightings and expressions — which stands a +much better chance against the gallery than any constituent track. + +**The evidence is also better-conditioned.** AR-025 warns that consecutive frames +within a track are highly correlated and must be discounted. Embeddings from +*different tracks* are far more independent: different scenes, angles, lighting. +Pooled cross-track evidence is therefore worth more per observation than +within-track evidence, and the discount should reflect that. + +**Temporal exclusion is a free constraint.** Two tracks that **overlap in time +cannot be the same person** — the same fact AR-012 uses to detect missed cuts. This +is a cannot-link constraint on the clustering and it costs nothing to apply, +since track extents are already known. Use it: it prevents exactly the merge that +would otherwise pool two people who share the screen. + +**Clustering must be conservative.** A wrong merge pools two people and then +mis-identifies *both*, across every track in the cluster — strictly worse than +leaving them separate. Prefer many small correct clusters to few large ambiguous +ones; the merge threshold is a calibrated probability (AR-024), swept in VR-007. + +**Order of operations at end of playback:** + +1. Cluster TBI tracks under temporal cannot-link constraints. +2. Pool each cluster's embeddings into one composite identity. +3. Match each cluster against gallery + annex (one GEMM, A10). +4. Cluster crosses threshold → **every member track** emits presence for that + actor. +5. Cluster does not → it becomes one **unknown person** entity, not N orphan + tracks. + +That last point matters beyond recognition: it is the difference between asking a +human to label twelve disconnected faces and asking them to name one person who +appears in twelve places ([`../../SPEC.md`](../../SPEC.md) §4). It is also the +natural unit for anonymous presence, should that be adopted (AR-012, TBD). + +### Consequences + +- **The result aggregator cannot finalise at EOF-flush.** Owned tracks emit on + death as before, but the TBI pass runs after, and may add windows. Output is + written after re-identification completes, not when the last frame is read. +- **Expansion errors are now more costly.** A wrongly promoted embedding no + longer affects only later frames — it is applied to every unknown in the film + during the second pass. The AR-018 band is the guard, and its lower bound is the + part doing that work. +- **Iteration is possible but unspecified.** A TBI entry that becomes identified + could itself expand the gallery and enable further identifications — a fixpoint + loop. Whether to iterate to convergence, run one pass, or bound the rounds is + open (VR-007). + +**Current:** `src/gallery/track_gallery.hpp` implements a per-track diversity +buffer with eviction biased to gallery-far poses, admission and promotion both +gated on the AR-018 band in probability space, cleared on `is_cut`. Wired at +`identity_matcher_node.hpp:227`, cleared at `:126`; the calibration is handed +over at `:114`. + +**Gap:** all three quiet-signal conditions rather than only `is_cut`; and the +whole of AR-020 — the TBI queue, the deferred pass, and deferring output until it +completes. + +## AR-022 — Unidentified-track capture + +Persist everything needed to diagnose a miss — and everything a *human* would +need to resolve one. + +Scope note: the TBI queue of AR-020 is **not** debug-only, because deferred +re-identification depends on it. What is behind a flag is the *persisted output* +for tracks that survive re-assessment still unidentified; retaining stores until +the deferred pass runs is unconditional. + +For every track **still unidentified after the deferred pass (AR-020)**, store: + +- all embeddings on the track, +- the aligned 112×112 crops, +- **context crops** — a wider region around the face than the 112×112 aligned + crop, for a handful of representative frames per track; +- track metadata: `track_id`, first/last timestamp, frame count, per-frame + detector confidence and bbox, +- the best similarity achieved and which actor it was against, so near-misses are + distinguishable from faces with no gallery counterpart at all. + +**Why the context crop is a separate artifact.** The 112×112 crop is optimised +for ArcFace: tightly cropped, geometrically normalised, and frequently +unrecognisable to a person out of context. A human deciding *who this is* needs +the surrounding shot — hair, costume, who they are standing next to. This +requirement exists to serve the human-in-the-loop association capability +([`../../SPEC.md`](../../SPEC.md) §4), where the user names the face the pipeline +could not. + +Retain a bounded number of representative frames per track (largest/sharpest +detections), not every frame — an unidentified track can run for minutes. + +This is the raw material for deciding whether a miss is a gallery coverage +problem (actor absent or under-represented) or a threshold problem (actor present +but scored below acceptance). + +**Current:** only *promoted* mugshots are dumped, via `expand_debug_dir` +(`track_gallery.hpp`, guarded by `SAE_DEBUG`) — i.e. the successes, not the +failures. **Gap:** the whole requirement. Needs a flag (`--dump-unidentified +`), a per-track accumulator that survives until the track ends, and a +decision on retention: crops for a feature-length film are large, so default to +embeddings + metadata with crops opt-in. + +## AR-023 … AR-025 — Calibration, probability space, and per-track Bayesian accumulation + +**Every similarity in the pipeline is converted to a probability through the +sigmoid calibration before it is used or thresholded. No component compares raw +cosine values against a hand-set constant.** + +This is a system-wide rule, not a detail of identity matching. Raw cosine +thresholds are unfalsifiable magic numbers that mean different things for +different models, different galleries, and different face sizes; a calibrated +probability means the same thing everywhere. It replaces `track_max_embed_dist` +(0.7), `cut_revive_sim` (0.50), `expand_novelty_sim` (0.55) and +`expand_track_spread_max` (0.60) with quantities that can be reasoned about +jointly. + +### Per-frame evidence is a Bayesian update on the track + +Once similarities are probabilities, a track's identity is not a vote count — it +is a **posterior accumulated across the frames of that track**. Each frame +contributes a likelihood that this face is actor A; the track's belief is updated +frame by frame, and ownership (AR-012) is "posterior exceeds threshold" rather than +"≥ N accepted frames". + +Working in **log-odds** makes this an addition per frame: + +``` +logit(A | frames 1..n) = logit_prior(A) + Σ_i [ logit(A | sim_i) − logit_prior(A) ] +``` + +This is strictly better than counting accepted frames: a long run of marginal +observations and a single decisive one are no longer conflated, and a track that +accumulates weak contrary evidence can lose ownership rather than keeping it on a +stale count. + +**The independence problem, which must be handled explicitly.** Consecutive +frames of one track are highly correlated — near-identical pose, lighting and +expression. Treating them as independent observations overcounts evidence +dramatically: thirty frames of the same face at the same angle is nowhere near +thirty independent measurements, and naive accumulation will drive the posterior +to certainty on what is effectively one observation. + +Mitigations, in preference order: + +1. **Update only on sufficiently novel observations.** The diversity buffer + (AR-018…AR-021) already identifies which embeddings on a track are gallery-far and + mutually distinct — precisely the more-independent ones. Reuse that judgement + rather than inventing a second one. +2. **Discount correlated updates** by a per-frame weight below 1, fitted so the + accumulated posterior is calibrated against held-out tracks. +3. **Cap total evidence per track**, the crude fallback. + +Whichever is chosen, the accumulated posterior must be **validated against +ground truth** — a posterior of 0.99 should be wrong about 1% of the time. If it +is not, the independence handling is inadequate and the number is decoration. + +### Fitting the calibration + +Build a PDF of **intra-subject** similarity and a PDF of **inter-subject** +similarity across the gallery; the prior is `intra / (intra + inter)`. + +- **Positive pairs** — same actor, different reference images. +- **Negative pairs** — all cross-actor pairs. +- Near-duplicate references are de-duplicated per actor first (similarity above + `1 − 1e-7`), so the same image embedded twice cannot inflate the positive side. +- Actors with fewer than 5 distinct embeddings contribute negatives only — they + cannot supply a meaningful positive pair. +- A Platt-style sigmoid `P(match) = σ(a·sim + b)` is fitted to the two + distributions with class weights balancing the (heavily skewed) pos/neg ratio. +- The base rate enters as log-prior-odds: `P = σ(a·sim + b + log(p₀/(1−p₀)))`, + with `p₀ = match_prior`. +- Acceptance is `P(match | sim, prior) > prob_threshold` (default 0.754, DE-tuned). +- **Fallback** when calibration is invalid (too few positive pairs): a hard cosine + distance ceiling `match_threshold`, OR a ratio test — accept if + `best/second < match_ratio` and `best_distance < match_ratio_ceil`. + +**Current:** `src/gallery/gallery_calibration.hpp` implements the sigmoid fit, +dedup, eligibility filter, and prior adjustment; the fallback lives at +`identity_matcher_node.hpp:181-196`. **Gap:** the fit currently histograms the two +similarity distributions internally (`kHistBins = 200`) but does not *emit* them. +For this requirement to be inspectable, the intra/inter PDFs and the derived +prior should be written alongside the gallery, so calibration quality is +auditable rather than implicit. Also note the shipped `match_prior` default is +0.5 (use the calibrated sigmoid directly) rather than the gallery-derived +`intra/(intra+inter)` — reconcile: either compute and store it at gallery-build +time, or document 0.5 as a deliberate override. + +## AR-026, AR-027 — Scale — performance must hold for arbitrary gallery size + +**Requirement: analysis throughput must remain acceptable as the gallery grows +arbitrarily large.** Gallery size is set by the user's library, not by us: a +whole-library gallery spans every credited actor across every title +(GR-001), which is thousands today and grows monotonically as titles are added. A +design that is fast at 500 actors and unusable at 50,000 has a defect, not a +limitation. + +### Similarity is a matrix multiply + +Every embedding is unit-norm (AR-006), so cosine similarity is a dot product and +scoring a batch of faces against the gallery is one GEMM. At library scale that +is the only viable formulation — a per-pair loop is orders of magnitude off. + +**All similarity computation goes through the GEMM path**, with no exception +justified by "this set is small". Three call sites: + +1. **Baked gallery** — GEMM (`sim_engine_->compute()`, backend from + `SAE_GEMM_BACKEND`). ✓ +2. **Per-film annex** — was a **CPU loop**, justified in-comment by "tens of + embeddings". AR-018…AR-021 invalidated that assumption: every owned track + contributes, so the annex grows with cast size and film length. Now appended + to the gallery matrix rather than scored separately — promotions are pushed + into the engine's resident matrix (`ISimilarityEngine::append_rows`, + capacity doubling, device-to-device on the GPU backends) and `flat_actor_` + grows in lockstep, so one multiply covers baked and promoted references and + best-of-N is a single pass over one similarity column. ✓ +3. **Deferred TBI pass (AR-020)** — the most GEMM-friendly operation in the + pipeline: all TBI embeddings against the full gallery-plus-annex, offline, + operands resident, no streaming. One large multiply, not a loop over entries. + Not yet built; AR-020 owns it. + +**Current:** 1 and 2 done. `TrackGallery` holds the annex as a contiguous +row-major matrix plus a parallel actor index, and hands newly promoted rows to +the matcher once per frame (`drain_promotions`), which is what call site 3 will +score against. + +**Gap:** call site 3, gated on AR-020 existing at all. + +This constrains AR-018…AR-021's implementation: the annex must be a **contiguous matrix** +with promotions appended, plus a parallel actor-index mapping — exactly the +`flat_emb_`/`flat_actor_` arrangement the baked gallery already uses. + +**Ordering note.** Absorbing promotions is a once-per-frame step that runs after +every face in the frame has been scored, not mid-frame. Appending mid-frame would +invalidate the similarity pointer the matcher is still reading, and it also +removes an accidental dependence on face order within a frame: a promotion helps +subsequent frames, never the one that produced it, which is the semantics the +expansion store already documents. + +**The CPU GEMM path requires OpenBLAS.** It is what CI and the cpu builder image +run, so a silent fall back to the scalar loop would mean AR-027 is measured — or +believed — on a path no release uses. Absence is a configure error; the scalar +loop survives as the correctness oracle, reachable only via +`-DSAE_ALLOW_SCALAR_GEMM=ON`. + +### Scaling characteristics that must be known, not assumed + +- **Throughput versus gallery size must be measured** (VR-008) and published. The + useful output is the curve and the point where gallery scoring starts to + dominate total runtime, not a single number. +- **Memory is a real ceiling.** 512 floats × 4 bytes = 2 KB per reference. At + five references per actor that is ~10 MB per 1000 actors — comfortable at + 10,000 actors, worth planning for beyond. +- **Calibration cost grows quadratically.** AR-023 fits on cross-actor pairs, which + is O(N²) in references. This is a gallery-build cost, not a per-title one, but + it will bite first — sampling negatives rather than enumerating them is the + obvious mitigation and should be specified before it becomes urgent. + +### If GEMM stops being enough + +Approximate nearest-neighbour indexing (IVF/HNSW) is the standard next step, and +it trades **exactness** for speed. That trade interacts badly with AR-023: an +approximate search returns approximate similarities, and a calibrated posterior +built on them is no longer calibrated. Not ruled out, but it requires +re-validating calibration against the approximation — so it is a later decision +with a real cost, not a drop-in. + +**Gap:** annex GEMM path; the scaling benchmark (VR-008); negative-pair sampling in +calibration. + +--- + +# Part B — Deployment requirements + +The pipeline must support **multiple deployment modes over one core**.

TRT engines are still built locally + either way (DP-008). +- An installer (`scripts/build_install.py`) consuming one `install.yaml`: + platform (nvidia/amd/cpu), embedder model, gallery scan cadence, install + prefix; runtime secrets written to a `.env`, editable without recompiling. +- Distro coverage: Fedora + Arch (`dnf`/`pacman`), auto-installing dependencies + after printing them.

The scalar fallback is correct but scales badly, which +would make the CPU path the bottleneck in the one place it cannot be avoided +(AR-027). The build warns when it is missing rather than failing, so a developer +without it still gets a working tree; the image must not be that case. + +The test target links it too. Otherwise the suite compiles the scalar fallback +while the image ships CBLAS, and CI would verify a kernel that is not the one +running in production. + +**Deliberately excluded:** CUDA, TensorRT, ROCm — no GPU to use them. Also the +ONNX Runtime *GPU* providers; only the CPU provider is relevant, and only for T3 +smoke tests. + +**Models are not baked into the image.** The seven ONNX files total ~725 MB and +live in Git LFS. T1/T2 tests are model-free by design +(`tests/CMakeLists.txt:1-4`), so the default image needs none. T3 smoke tests +require a model and should pull it via LFS in a separate job rather than +inflating the image tenfold for a minority of tests. + +**`libswresample` is a real gap, not a formality.** The current +`pkg_check_modules` list (`CMakeLists.txt:200-203`) covers avformat, avcodec, +avutil and swscale but **not** swresample — which IR-004 needs to downmix to mono +and resample to 11025 Hz. It must be added alongside the audio-signature work. + +**Gap:** entire requirement. The image does not exist, and no CI config is +present in this repo. + +## DP-008 — Builder images and release binaries + +Produce prebuilt binaries per backend so deployment does not require every user +to compile the project. + +**This does not contradict DP-005.** That requirement rejects Docker as a +*runtime* — GPU passthrough is the most fragile part of a containerised setup and +exists only because of the container. Using Docker as a *build* environment is +the opposite case: hermetic, reproducible, and it lets one machine produce +binaries for backends it cannot itself run. Build in a container; run natively. + +### Image matrix + +The build has two independent axes (`CMakeLists.txt:48-49`), so the useful +combinations are: + +| Image | `SAE_INFERENCE_BACKEND` | `SAE_GEMM_BACKEND` | Target | +|---|---|---|---| +| `sae-builder-cpu` | ORT | CPU | CI (DP-007), and the smoke-test fallback | +| `sae-builder-cuda` | TRT | CUDA | NVIDIA | +| `sae-builder-rocm` | ORT | ROCM | AMD | + +All three carry the DP-007 dependency set (OpenCV 5, HDF5, FFmpeg incl. +swresample, vendored Catch2/nlohmann) and differ only in the accelerator stack. +The CPU image is the CI image — one artifact, two uses. + +Published to the Gitea container registry, pinned by tag, rebuilt when the +dependency set changes rather than per run. + +### What ships, and what cannot + +**Ships:** the `scene_analyze` binary and its companions, per backend. + +**Cannot ship: TensorRT engines.** `.engine` files are specific to the GPU +architecture and TRT version they were built on — `scripts/build_trt_engines.sh` +must still run on the target machine. A prebuilt binary shortens the install; it +does not remove the local engine-build step, and the installer must not imply +otherwise. + +**Cannot ship: models.** ~725 MB in LFS, and orthogonal to the binary. + +### The constraint that decides the base image + +**A binary built in a container runs against the host's glibc.** Build on a +newer base than the oldest supported host and it fails at load with +`GLIBC_2.xx not found` — the classic and entirely avoidable trap when shipping +binaries out of containers. + +So the base is chosen for the *oldest* glibc to be supported, not for +convenience or recency. Accelerator libraries have the same shape of problem: +the binary links against a driver-provided runtime, so each image must document +the CUDA/ROCm version range its output is compatible with, and the installer +must check it rather than discovering a mismatch at first inference. + +### Jobs + +A release job per backend, producing a tagged artifact in the registry. These are +**not** the CI gate — the gate runs the CPU image on every push (DP-007); +release builds run on tag.

No images, no release jobs. + +## DP-006 — Gallery maintenance as a background concern + +- Incremental gallery refresh runs on a timer (`gallery_scan_interval`, default + 24 h) independently of analysis, so newly added titles' cast is embedded before + their media is analysed. +- A gallery/model mismatch must be detected **at startup**, not silently produce + garbage similarities.

Default is + **global**. +- Optionally, the `tmdb_id`s of the actors the gallery was built from — useful + for reproducibility locally. Not proposed for the Jmanifest, where a + thousand-entry id list is bulk for little gain over `gallery_size` + scope. + +Format is owned by [`../../jRay/SPEC.md`](../../jRay/SPEC.md); this pipeline is +the producer. Any change is a coordinated schema-version bump. + +**Current:** `result_sink_node.hpp`. **Gap:** the schema changes in several ways +at once — `anneal_sec` out, `extinction_sec` and `gallery_scope` in, per-window +belief added, audio signature added (IR-004). All breaking, so they ship as **one** +`schema_version` bump coordinated across all three repos.

Offsets are applied client-side; manifests are never +rewritten. + +**Media shorter than 120 s.** The window `runtime/2 ± 60 s` underflows, so no +signature is emitted and **no sync offset is applied**. Such items fall back to +the runtime tier, which is adequate: a 90-second extra or trailer is not the +content whose cut alignment matters. (There is no `exact` tier: the file-hash +tier was withdrawn on legal grounds — it fingerprinted an individual copy rather +than the cut the timings describe. See the server spec §3.) Both producers must apply the identical +rule, or they diverge on exactly the short items most likely to be +mis-identified. + +**Signature versioning.** The signature carries its own `v1:` prefix, separate +from `schema_version` (server spec §3 example: `"v1:v7fA3k…"`). Emit and honour +it, so a future change to the DSP chain is *detectable* rather than silently +producing non-matching signatures. + +**Decision (this spec):** the pipeline computes and emits it *in addition to* the +plugin. Consequences to carry through: + +- The truth schema gains a field → **`schema_version` bump**, coordinated with + `jRay/SPEC.md` and the plugin. +- The pipeline needs an audio decode path. It already links FFmpeg + (`ffmpeg_decoder.hpp`) for video, so this is a second stream from an existing + dependency, not a new one. +- Both producers must agree bit-for-bit. A cross-check test — plugin signature vs. + pipeline signature over the same file — is a hard requirement, not a nicety. +- Files never processed by this pipeline still get a signature from the plugin; + the two paths coexist deliberately. + +**Current:** `src/audio_signature.*` implements the construction, and +`tests/fixtures/audio/` holds the golden vector shared verbatim with the plugin +repo, which now matches it byte for byte from C# (jRay `JR-042`/`JR-043`). +`sae_audio` (nanobind, as `sae_embed` and `sae_kpn` are) exposes the same C++ to +Python so a study drives the shipped code rather than a numpy port. + +**VR-014 measures what the golden vector cannot** — that the signature actually +aligns a differently trimmed release, on real film audio rather than a synthetic +tone. It does, with an order of magnitude to spare. + +**The accuracy question is settled and is not close.** What the offset is *for* +is shifting scene windows, which are seconds long, so half a second of error is +invisible; the budget is 500 ms. Over 40 random offsets inside the ±600-frame cap +the recovered offset was the nearest frame every time — **worst error 46 ms**. +That figure is the quantisation floor rather than a measurement of quality: the +offset is expressed in whole 92.88 ms frames, so no correct answer can ever be +worse than half a frame. The `runtime/2` anchor behaves as specified through real +head-trimmed files (cutting `delta` from the head moves the window by +`delta/2`), and both an out-of-cap offset and unrelated content are declined +outright (0.10 and 0.07). + +**Where it is soft is tier labelling, not alignment.** The *score* at the correct +offset falls with sub-frame misalignment — 0.94–0.99 when the true offset lands +within 0.1 of a frame boundary, 0.69–0.73 at half a frame — because the two +windows' frame grids no longer coincide. The offset stays right, but only 13 of +40 cleared the server's 0.85 `audio` threshold and the other 27 were demoted to +`loose`, a tier that means "possibly the same cut, degraded audio". The threshold +was calibrated on a re-encode at *zero* offset, where the score is 1.00. + +The remedy is measured, not proposed (UT-108): counting a frame as agreeing if +its peak bin matches **within ±1 frame** returns all 40 to `audio` (worst 0.906) +while unrelated content and out-of-cap offsets stay at 0.12 and 0.16 — the gap +that makes the threshold mean anything is untouched. It costs 81 ms of offset +accuracy, of a 500 ms budget, because the flattened peak lets the argmax pick an +adjacent frame. ±2 frames buys nothing further. Adopting it is a +[server spec](../../JRay-public-server/SPEC.md) §3 change — the score is +normative and shared by three repos — so this repo measures it and leaves the +decision there. + +**Gap:** the signature is computed but **not yet emitted** into the truth file — +that is the `IR-002` field and the coordinated `schema_version` bump. + +## IR-006 — Jellyfin round-trip + +- Pull the work queue: `GET /Plugins/JRay/Tasks/Pending?limit=N` — items with no + results yet. +- Push results: `PUT /Plugins/JRay/Items/{itemId}/Truth` (admin API key).

Dedup and eligibility are computed inside calibration but not +surfaced as a build report. + +## GR-004 — Model binding + +- A gallery is only valid for the embedder that built it.

Stored as the `/embedder` +group in the gallery HDF5, and as an optional top-level `"embedder"` object in +the legacy JSON format. + +The hash *decides*; the name is what a human *reads*. Neither alone is enough. A +name is a promise rather than a fact — models get re-exported, re-quantised and +overwritten in place under an unchanged filename, which is exactly the case where +the weights differ and nothing else does, so a name-only stamp is blind to the +failure it exists to catch. A hash alone is correct but unactionable: *"expected +3f2a…, got 9c1b…"* tells an operator nothing about what to do next. SHA-256 over +the file is derived from the artefact rather than asserted about it, needs no +registry kept up to date, and costs ~0.1 s for a 250 MB ONNX once per process. + +### Verdicts + +| Verdict | When | Default | Under strict mode | +|---|---|---|---| +| `match` | hashes agree | proceed | proceed | +| `weak_match` | names agree, one side unhashable | **warn** | **error** | +| `unstamped` | gallery predates GR-004 | **warn** | **error** | +| `unknown_embedder` | gallery stamped, embedder unidentifiable | **warn** | **error** | +| `mismatch` | proven different models | **error** | **error** | + +**A mismatch is fatal in every mode, with no bypass**, and the message names both +sides — what the gallery was built with and what is loaded. + +The three "cannot prove it" verdicts warn loudly instead, because they describe an +*unknown* state rather than a *known-bad* one, and because every gallery built +before this requirement is unstamped. Hard-failing all of them would make the +check something people route around rather than trust. Strict mode +(`--require-gallery-stamp`, or `SAE_REQUIRE_GALLERY_STAMP=1`, which propagates to +subprocesses) promotes them to errors — that is the mode measurement work runs in. +`scripts/stamp_gallery.py` re-binds an existing gallery without re-embedding, so +migration costs one command; that is what makes "warn" a temporary state rather +than a permanent one. + +### Scope of the check + +Embedding **dumps** carry the same stamp (`embedder_model` / `embedder_sha256` +root attributes, `scripts/optimizer/SCHEMA.md`): a replay has no live embedder, so +the dump *is* the embedder as far as the gallery is concerned.

The tier must be recorded per embedding so that a suspected +poisoning can be traced, audited, and reverted without rebuilding the gallery. + +### Bell-curve outlier detection + +An actor's own embeddings should form a **roughly normal distribution in cosine +space** around their centroid.

Select ~100 gallery actors having more than one mugshot. +2. Per actor, hold out **one** image as the probe; its remaining images stay in + the gallery at native resolution. +3. For each target size *S*, downscale the probe to *S*×*S* and upscale back to + 112×112, then embed. +4. Match each degraded probe against the full 100-actor gallery and record + **TPI/FPI** — identified as the correct actor, or as someone else. +5. Repeat across sizes to get the curve. + +The asymmetry is the point: **the gallery stays high-res and only the probe +degrades**, which is exactly the production case — reference mugshots are clean, +the face from the video is small. It also measures the decision the pipeline +actually makes (probe against gallery) rather than embedding drift, which can be +large without harming separability and small in a direction that destroys it. + +**Caveat on gallery size.** FPI grows with the number of actors competing, so a +100-actor gallery understates the false-positive rate against a full library of +thousands. Treat the FPI numbers as *relative* across sizes rather than as an +absolute rate, or re-run at production scale before setting a threshold from +them. + +**Cheap to run** — no video needed, gallery images are already on disk, and the +embedding/matching machinery exists (`scripts/sae_embed_loader.py`, +`gallery_calibration.hpp`). Expect a knee rather than a cliff; the output is a +size-versus-TPI/FPI curve plus a chosen operating point, not a single number. + +**Secondary output:** the same curve shows whether `min_face_px` should be a +constant at all or should scale per embedder — relevant since the model is a +build-time choice (GR-004). + +## VR-007 — Expansion band and deferred-pass study + +Tune the AR-018 admission band and establish whether AR-020 pays. + +**Band.** Sweep the lower and upper bounds around the 0.90–0.95 working estimate. +The two bounds fail in opposite directions and must be read separately: too low a +lower bound admits the wrong person (precision collapse, amplified by the +deferred pass); too low an upper bound admits only redundant views (no recall +gain, wasted annex). Report both, not a single F1. + +**Deferred pass.** Measure recall recovered by AR-020 — how many TBI entries are +identified on re-assessment — and precision of those late identifications +specifically. They should be scrutinised separately from first-pass +identifications, because they are the ones relying on harvested rather than baked +references. + +**Clustering (AR-021).** Sweep the merge threshold and report cluster purity +against known-cast ground truth, not just downstream F1. The two error modes are +asymmetric and must be reported separately: an over-merge mis-identifies every +track in the cluster at once, while an under-merge only forfeits the pooling +benefit. Verify the temporal cannot-link constraint is actually binding — measure +how many candidate merges it rejects, since if the answer is zero the constraint +is not doing the work claimed for it. + +**Iteration.** Test one pass versus iterating to convergence (AR-020). Report +whether round 2+ recovers enough to justify the complexity, and whether precision +degrades with each round — the failure mode being a wrong identification in +round 1 seeding references that corrupt round 2. + +**Ablation worth having:** expansion on with deferred pass off. It separates +"expansion helps live matching" from "expansion helps the second pass", which the +current all-or-nothing `expand_gallery` flag cannot distinguish. + +## VR-015 — Per-node cost and bottleneck attribution + +**Requirement: a run must be able to report where its time went, per node, and +which node is setting the pace.** Without it, optimisation is guesswork, and +worse than guesswork — the obvious number is wrong in a specific, repeatable +direction, so acting on it makes the pipeline slower. + +**Why the obvious number is wrong.** KPN times a node across `fire_once`, which +wraps the functor *and* `push_outputs`. Under AR-004 a push parks on a full +downstream channel, so a node that is merely waiting bills that wait to itself. +On the SuperHero reference run (`docs/benchmark.md`) `frame_source` reported +`ema=141.899ms` per frame while its own decoder logged 12-18 ms: it was +backpressured, and the report named the *fastest* node in the graph as the most +expensive one. A second trap sits behind the first — `ema_exec_ms` is an +exponentially weighted average, so `frames × ema` is not a total; on a film whose +per-frame cost swings between crowd scenes and landscapes the two differ +substantially. + +**Method.** Three measurements per node, none of which is sufficient alone: + +| Measure | What it is | What it cannot tell you | +|---|---|---| +| `cpu_ms` | thread CPU time (`CLOCK_THREAD_CPUTIME_ID`) | GPU wait — a device-bound node looks idle | +| `exec_ms` | cumulative wall time inside the node | work from waiting — backpressure inflates it | +| `pressure` | mean input fill − mean output fill | how expensive the node is, only that it paces | + +Queue occupancy has to be **sampled during the run**. `current_fill` is +instantaneous and every channel has drained by shutdown, so a single read at the +end describes an idle pipeline however congested it was. + +**The number that matters** is `pressure`, because work piles up in front of the +bottleneck and starves everything after it, and that ordering holds whether the +node is waiting on a core, a GPU or a disk. `cpu_share` then selects the repair: +a pacing node with a saturated thread is CPU-bound and the work must get cheaper, +while a pacing node with an idle thread is device-bound, where batch size and +engine precision are the knobs and the C++ is not. + +**Current:** `--benchmark ` writes the JSON report and prints a table at +shutdown; `src/benchmark.hpp`. Attribution is a pure function over KPN snapshots, +so it is verified on CI's GPU-free N100 (UT-120…UT-124) rather than only by +running the pipeline. The node graph is recovered from KPN's channel names, so a +re-wired topology needs no change here. Required `NodeStats::total_exec_us` in +the KPN submodule — the EMA could not be turned into a total. + +**Gap:** GPU utilisation and memory are not sampled, so a device-bound verdict +says *that* a node waits on the GPU, not whether the GPU is saturated or merely +badly fed. That distinction needs NVML, and it is what VR-008 will want anyway. + +## VR-008 — Gallery scaling benchmark + +Establish the throughput-versus-gallery-size curve required by A10. + +**Method.** Synthesise galleries at 10², 10³, 10⁴, 10⁵ actors (random unit-norm +embeddings suffice — this measures compute, not accuracy) and record per-frame +matching time, end-to-end throughput, and GPU memory. + +**The number that matters** is where gallery scoring stops being negligible and +starts dominating runtime relative to decode, detection and embedding. Below that +point gallery growth is free; above it, it sets the pace. + +**Also measure the deferred pass (AR-020) separately.** It has a different shape — +one large offline multiply rather than many small streaming ones — so it may +scale quite differently and could well become the dominant cost on a film with +many unknowns. + +**Report calibration build time too.** AR-023's cross-actor pair enumeration is +O(N²); this benchmark is where that becomes visible, and it will likely be the +first thing to break at scale. + +## VR-006 — Re-tune `scene_threshold` at native rate + +Not a study of whether to feed TransNetV2 correctly — AR-011 settles that it must be. +This is the consequence: `scene_threshold` (0.60) was picked against 12 fps input, +where the model's separation was compressed. At native rate the boundary/ +non-boundary margin should widen, so the operating point moves. + +Small and mechanical: score boundaries across a threshold range on a few titles +once native-rate decode lands, and pick the new point. Expect a cleaner +separation than the ~0.50 baseline / ~0.7+ peak recorded at 12 fps; if it does +*not* improve, that is evidence worth having about the export itself. + +--- + +# Open questions + +Resolved during planning, recorded here so the reasoning is not lost: + +- ~~**AR-012 vs. extinction.**~~ Wholly subsumed. The `last_seen` model ends windows + at the last sighting, which removes the over-claim `extinction_sec` caused; + both it and `anneal_sec` are deleted rather than re-fitted (AR-012 withdrawal note). +- ~~**AR-022 retention.**~~ Embeddings + metadata by default, crops opt-in behind + `--dump-unidentified-crops`. +- ~~**IR-004 bit-exactness.**~~ Golden-vector fixture checked into both repos, not a + shared implementation — the coupling cost of the latter exceeds the benefit. +- ~~**AR-023 prior.**~~ Decide once GR-003 persists the intra/inter distributions, so the + real value is known rather than argued about. + +Still open (pipeline-local): + +1. **Re-acquisition timeout scope.** `track_max_frames_missing` (5) and + `cut_inactive_max_frames` (5) currently distinguish an ordinary miss from a + cross-cut park.

The raw `rep4_best_*.json` files, and an +earlier version of this table, reported a different `arcface_w600k_mbf_full_noexp` +row: **74.2% F1 at TPI 12645**, a third the TPI of every sibling combo. That was +not a better config; it was an artifact of how the optimizer aggregates. + +`optimize.py` builds each candidate's score from only the films whose replay +subprocess returned (`per_film = [m for m in ex.map(_one, films) if m is not +None]`), then **averages** F1/precision/recall and **sums** TPI/FPI/misID over +just those survivors. When a film's replay times out (the sweep ran near the +8-process concurrency ceiling, so this happened intermittently), that film +silently drops from both. A candidate whose hardest film timed out is therefore +scored on an easier subset, and differential evolution, maximizing that score, +will happily converge onto exactly such a candidate. For `mbf_full_noexp` the +reported winner was one of 7 evaluations (out of 512) whose TPI had collapsed to +a partial-film subset; its median-coverage evaluations sit around 51686 TPI. + +The fix here was to re-derive each combo's best row from its DE trajectory +(`experiments/trajectories/rep4_*.jsonl`), keeping only evaluations within 30% of +that combo's median TPI (full 4-film coverage) before taking the best F1. This +needs no re-running, the honest best configuration was already in the sweep, +just not the one `argmax F1` selected. Three combos moved: `mbf_full_noexp` +74.2% → **71.0%**, `LVFace_full_noexp` 72.4% → **72.3%** (and its misID, 0 → 244, +was itself a dropped-film artifact), `mbf_restricted_exp` 76.5% → **76.2%**. The +shipped LVFace `full_exp` winner was unaffected, its reported evaluation already +had full coverage (TPI 47757 ≈ median). `experiment_charts.py` applies the same +`clean_best` filter, so every figure on this page matches the corrected table. +The underlying `optimize.py` aggregation is also being fixed so a dropped-film +evaluation can never be selected as a winner again. + +### Per-film training breakdown + +The 75.3% LVFace training figure is a macro average across 4 films, not a +uniform result: + +| film | LVFace F1 | mbf F1 | r18 F1 | best model | +|---|---|---|---|---| +| Café Society | 68.1% | 62.2% | 60.1% | LVFace | +| Lord of War | 75.6% | 77.2% | 75.6% | mbf | +| Scarface | 71.5% | 68.6% | 64.1% | LVFace | +| Sound of Metal | 78.8% | 76.5% | 71.6% | LVFace | + +LVFace does not win every training film. mbf scores higher on Lord of War +(77.2% vs 75.6%).

This is not a precision/recall +trade: +4.8pp F1, +6.0pp recall, and roughly a quarter the misIDs.

Restriction is currently an offline optimizer technique, not a +runtime feature of the application; see +[Whole vs. cast-restricted gallery](gallery-scope-2026-07.md) for what building it +into the application would require. + +**Pose expansion** (promoting a confidently identified track's novel-pose +views into a per-film gallery annex, +[`src/gallery/track_gallery.hpp`](https://REPOLINK/src/gallery/track_gallery.hpp)): + +| scope | expansion | F1 | R | misID | +|---|---|---|---|---| +| full | off | 70.0% | 57.6% | 407 | +| full | on | 72.1% | 61.5% | 714 | +| restricted | off | 75.1% | 63.9% | 179 | +| restricted | on | 76.7% | 67.2% | 120 | + +In restricted mode, expansion is a clean win: +1.6pp F1, +3.3pp recall, +misID drops.

In full mode, expansion buys +2.1pp F1 and +3.9pp recall but at a real +cost: misID rises from 407 to 714 as the same new-pose view now competes +against the full 2418-actor gallery, where a confidently learned pose is more +likely to match the wrong person.

The raw `rep4_best_*.json` files, and an -earlier version of this table, reported a different `arcface_w600k_mbf_full_noexp` -row: **74.2% F1 at TPI 12645**, a third the TPI of every sibling combo. That was -not a better config; it was an artifact of how the optimizer aggregates. +`scripts/optimizer/dump_error_frames.py` pulls representative seconds and draws +each face box against X-Ray's scene cast: **green** = true positive, **red** = +false positive (a name X-Ray does not credit to this scene — the real error), +**orange** = an unknown detection. Cast X-Ray lists as present but for whom no face +was detected — the structural false-negatives a face pipeline can never box — are +listed as a **blue** panel. -`optimize.py` builds each candidate's score from only the films whose replay -subprocess returned (`per_film = [m for m in ex.map(_one, films) if m is not -None]`), then **averages** F1/precision/recall and **sums** TPI/FPI/misID over -just those survivors. When a film's replay times out (the sweep ran near the -8-process concurrency ceiling, so this happened intermittently), that film -silently drops from both. A candidate whose hardest film timed out is therefore -scored on an easier subset, and differential evolution, maximizing that score, -will happily converge onto exactly such a candidate. For `mbf_full_noexp` the -reported winner was one of 7 evaluations (out of 512) whose TPI had collapsed to -a partial-film subset; its median-coverage evaluations sit around 51686 TPI. +![A correctly identified second: green true-positive boxes](assets/images/lovelace_perfect_second.jpg) -The fix here was to re-derive each combo's best row from its DE trajectory -(`experiments/trajectories/rep4_*.jsonl`), keeping only evaluations within 30% of -that combo's median TPI (full 4-film coverage) before taking the best F1. This -needs no re-running, the honest best configuration was already in the sweep, -just not the one `argmax F1` selected. Three combos moved: `mbf_full_noexp` -74.2% → **71.0%**, `LVFace_full_noexp` 72.4% → **72.3%** (and its misID, 0 → 244, -was itself a dropped-film artifact), `mbf_restricted_exp` 76.5% → **76.2%**. The -shipped LVFace `full_exp` winner was unaffected, its reported evaluation already -had full coverage (TPI 47757 ≈ median). `experiment_charts.py` applies the same -`clean_best` filter, so every figure on this page matches the corrected table. -The underlying `optimize.py` aggregation is also being fixed so a dropped-film -evaluation can never be selected as a winner again. +Every named frame in this documentation is regenerated against the current opencv5 +pipeline by [`scripts/scene_detector/rematch_frames.py`](https://REPOLINK/scripts/scene_detector/rematch_frames.py), +which auto-matches each example by film, actor, and class (TP/FP) so the images +never drift from the shipped behaviour.

Tally and verdict must be + read under one lock as a snapshot, or a track can be both unowned and owned + within a single promotion decision. +- `on_vote()` arrives downstream of the tracker's `tick()` for the same frame, so + a vote may land after the clock moved on. **Rule: a vote for a known track + always lands on its tally, regardless of clock.** Only reaping is clock-driven. + A vote for an already-reaped track is dropped and **counted** — a nonzero count + means the timeout is shorter than the matcher's lag. + +`on_track_dead` fires from inside `tick()` while the frame lock is held, so the +callback must not re-enter the registry. Keep it to a push onto the aggregator's +storage. + +## AR-016 — EOF flush + +**Depends on:** AR-012. + +`flush()` emits every still-live track through the same callback, closing at +`last_seen` if set and the final tick timestamp otherwise. Idempotent, leaving the +registry empty; the sink's `written_.exchange(true)` guard +(`result_sink_node.hpp:66`) shows the shape. + +Must run on **every** termination path that produces output. Not SIGTERM during +opportunistic runs (DP-004) — those push no partial result, so there is nothing +to flush. + +Without it a film ending mid-shot silently drops its closing cast, which looks +like a recognition miss rather than a bookkeeping bug. + +## AR-014, AR-015 — Contradiction rules + +**Depends on:** AR-012, AR-025. + +| Condition | Meaning | Action | +|---|---|---| +| Belief on one track swaps A → B | `track_id` carried across a viewpoint change onto a different person | Close at `last_seen`, open a new track for B at the swap frame | +| Two **live** tracks owned by one actor | One person split in two, or an identity attached to the wrong track | Treat as a detected cut: reset affected state, re-associate on embedding | + +The second makes identity a **third cut detector**, independent of histogram and +TransNetV2, firing where those failed. Detect it via a reverse index +`actor_idx → live track_ids`, so the condition is caught on the update that +causes it rather than by scanning. + +Both counted and reported — the rates measure how often tracking is silently +wrong, which nothing currently reveals. + +## AR-007, AR-008 — Tracker on one pool + +**Depends on:** AR-012, AR-024. + +`FaceTrackerFunc` is constructed with the registry and uses it as state; its +`tracks_`/`inactive_` maps and the cross-cut revival branch collapse into one +pool keyed on `last_seen`. Per frame: `tick()`, association over `candidates()`, +then `create`/`mark_seen`/`mark_lost`. + +`track_alpha` becomes **frame-dependent** — normal frames use the tuned blend, +frames flagged `is_cut`/`is_scene_boundary` drop toward embedding-only. + +## AR-024 — Probability space everywhere + +**Depends on:** AR-023. **Blocks:** AR-007, AR-018, AR-021, AR-025. + +Cuts across tracker, matcher and expansion, so it lands with the registry work +rather than after it. Retires `track_max_embed_dist`, `cut_revive_sim`, +`expand_novelty_sim`, `expand_track_spread_max`. + +Enforcement is a **static grep check** for bare cosine outside a tagged +`EXCEPTION` — a unit test cannot prove absence across a codebase. + +## AR-025 — Bayesian accumulation + +**Depends on:** AR-023, AR-024. + +Log-odds per candidate actor, added per frame. `on_vote()` is an *update*, not an +increment. + +**The independence problem must be handled explicitly.** Consecutive frames are +highly correlated; naive accumulation drives the posterior to certainty on what is +effectively one observation. Preferred mitigation: update only on sufficiently +novel observations, reusing the diversity buffer's existing judgement rather than +inventing a second one. The registry should receive already-discounted evidence. + +## AR-017 — Claims carry belief and route + +**Depends on:** AR-012, AR-025. `DeadTrack` carries posterior plus how it was +identified (live / deferred / pooled). + +## AR-018 … AR-021 — Expansion, deferred pass, clustering + +**Depends on:** AR-012, AR-024, AR-026. + +Ordering within the group: AR-018 (banded store) → AR-019 (annex) → AR-020 (TBI +queue + deferred pass) → AR-021 (clustering). + +AR-021 needs the temporal cannot-link constraint from track extents, so it cannot +start before AR-012. The annex must be a **contiguous matrix** with promotions +appended (AR-026), not a list. + +**Output timing changes:** the sink can no longer finalise at EOF — the deferred +pass runs after and may add windows (IR-003). + +## AR-022 — Unidentified capture + +**Depends on:** AR-020.

Must block on bytes in flight, not item counts. +- **AR-003** — remove `max_faces`. **Gated on AR-004**, not a follow-up to it. + +## AR-026, AR-027 — GEMM and scale + +**Depends on:** nothing to start. The annex CPU loop has moved into the GEMM +path: the annex is a contiguous matrix, promotions are appended to the engine's +resident gallery, and the CPU backend now requires OpenBLAS. What is left of +AR-026 is call site 3, the deferred pass — so the rest of AR-026 lands *with* +AR-020 rather than before it. + +--- + +# Gallery + +## GR-004 — Model binding — **DONE** + +**Depended on:** nothing. Landed before any measurement work, as intended. + +Stamp = model basename + SHA-256 of the ONNX, written as the `/embedder` group at +build time (`gallery_builder.cpp`, `sae_gallery.save_gallery_hdf5`) and verified +at load in `scene_analyze`, `scene_preview`, the `sae_kpn` matcher binding, +`replay.py`, `optimize.py` and `movienet_eval.py`. Mismatch is a hard error naming +both sides, with no bypass. Embedding dumps carry the same stamp, since a replay +has no live embedder to check against. + +Unstamped legacy galleries **warn loudly and proceed** rather than failing: +unknown is not known-bad, and hard-failing every pre-existing gallery would turn +the check into something people disable. `--require-gallery-stamp` / +`SAE_REQUIRE_GALLERY_STAMP=1` promotes that to a hard error — measurement runs +should set it. `scripts/stamp_gallery.py` re-binds an existing gallery without +re-embedding, so the warning state is cheap to leave. + +Cross-model similarities are meaningless but *look* plausible — this fails +silently and expensively, and it would corrupt every measurement taken during the +rest of this work. + +## GR-003 — Coverage reporting + +**Depends on:** nothing.

Standalone Python, no C++ contact. **Done** — knee at +24–32 px. It measures the embedder with alignment held perfect, so it bounds the +answer from below rather than setting it; AR-002's floor comes from **VR-013**, +which sweeps input resolution end to end and lands at 40 px. + +## VR-013 — Cross-source identification probe + +**Depends on:** `sae_embed` exposing `detect()`, `align_face()`, `embed_crop()` +and the gallery calibration — it drives the shipped C++ rather than reimplementing +it, which is what VR-005 could not do. + +Gallery from one recording, probes from another, sweeping the probe's **input +resolution before the detector**, so detection and landmark regression degrade +with the frame. `experiments/xsource/`. + +**Findings.** Holding 90% of the plateau needs ~50 px end to end against VR-005's +~22 px; `min_face_px` 40 is right and 32 would admit faces in the falling region. +FPI is 0.0% at every scale — resolution loss goes entirely to TBI, never to a +wrong name. The ceiling is **cross-view, not resolution**: everyone matches +themselves within a recording (0.55–0.85) and collapses across two (0.14–0.45), +and only the subject with frontal *gallery* references identified reliably — so +the lever is gallery pose coverage (`docs/pose-expansion.md`), not a better +landmark model. Averaging SCRFD's NMS-discarded landmark estimates lifts +cross-clip TPI 41% → 49% for one forward pass. + +**Open.** Four identities and one shoot, so the shape is the result and the +absolute rates are not. Both clips hold all four people, so there is no +out-of-gallery class and the 10×-weighted out-of-cast misID is untested — holding +one identity out of the gallery would fix that. + +## VR-014 — Audio-signature offset recovery + +**Depends on:** `sae_audio` exposing `compute_signature()` and +`signature_from_mono()` — it drives the shipped C++, as VR-013 does, so the +thing measured is the thing that ships. + +`scripts/validation/test_audio_offset.py` over +`tests/fixtures/audio/superhero_offset_200s.flac`: 200 s of public-domain film audio +(the same SuperHero clips the replay fixtures use), long enough for a 120 s +window to slide past the ±600-frame search cap. The slide itself is numpy here +on purpose — matching belongs to the consumer, so writing it out keeps this a +test of the signature rather than of somebody's matcher. + +**Findings.** Alignment is a solved problem here: the offset is the nearest frame +in every in-cap trial, worst error **46 ms against a 500 ms budget**, and 46 ms is +the quantisation floor — offsets are whole 92.88 ms frames, so no correct answer +can be worse. The `runtime/2` anchor's factor of two holds through real trimmed +files, and out-of-cap offsets and unrelated content are both declined. + +**The score is where the slack is, and it costs a tier rather than accuracy.** It +tracks sub-frame misalignment — 0.94–0.99 near a frame boundary, 0.69–0.73 at +half a frame — so two thirds of correct alignments miss the server's 0.85 `audio` +threshold and land in `loose`. UT-108 measures the fix rather than proposing one: +±1 frame of slack in the score returns all 40 to `audio` (min 0.906) with false +matches unmoved at 0.12–0.16, costing 81 ms of the budget. See +[`SPEC.md`](SPEC.md) IR-004 — the score is normative in the server spec, so the +change is theirs to make. + +**Open.** One source, one language, one era of recording.

Replaces `push_blocking`, which parked a scheduler worker inside the push and, with one thread per node, stopped that node draining its own input. Verified: 385/385 frames, 0 drops. Holes closed since, in the order they surfaced: **(a)** `FanoutNode` dropped on overflow rather than waiting, so the AR-010 scene join shed frames exactly when the dense branch fell behind — measured at **9 of 2192 items delivered** to the slower of two branches, now lossless with the fast branch throttled to within its buffering; **(b)** the residual hang, recorded as ~1 run in 20 at a 300 s timeout, was a **startup** lost wake, not a mid-stream one — `start()` enables a node's inputs several statements before it installs the push callback, and a producer firing into that gap is accepted by the ring while waking nobody, since `Channel::push` signals only the empty→non-empty edge. Signature is zero items delivered, never a partial stall. Reproduced 7 times in 24 under CPU contention and 0 in 10 without; `start()` now closes with the level-triggered `on_input_ready()`, giving 0 in 24 on the same harness — though the *cause* was narrower than recorded there and is fixed properly in **(e)**; **(c)** `FilterNode` and `RouterNode` were the last data paths still using the throwing `push()` with the exception swallowed, so a full output discarded the value — including the **EOF sentinel**. The decimator passes EOF by predicate (`if (f.eof) return true;`) but its output is reliably full, the embedder being the slowest node in the chain, so the token was discarded, nothing downstream ever shut down, and the run had to be killed. **This is the wedge.** Both now route sentinels out-of-band and retry data until taken; the regression case delivers 6 of 40 values and never sets `saw_eof` before, 40 and terminating after; **(d)** the sentinel could be delivered *ahead of* a value still queued behind it — `pop()` observed the ring empty and then took the sentinel, and a producer can push a value *and* publish the sentinel inside that window, so any consumer treating EOF as a hard stop loses the tail. `take_sentinel` now re-checks emptiness *after* observing `has_eof_`, which is sound because the sentinel is published with a release store after the ring pushes. ~1 run in 15 before, 0 in 25 after; **(e)** two `fire_once` invocations for one node could overlap, because the submit gate was released before the firing had finished touching node state. That breaks the one-slot park the whole scheme rests on — a parked value can be overwritten by the other firing, with no drop recorded anywhere. ThreadSanitizer caught it as a race on `pending_done_`; the release is now the last act of a firing. The same sweep found the callbacks themselves being written while a running neighbour read them (ten TSan races), which is the *actual* cause of the startup lost wake in **(b)** — callbacks are now installed in a `prepare()` pass before any node starts. **New constraint:** a channel carries at most **one undelivered sentinel**; a second offered before the first is taken is refused and reported, never queued and never overwritten, since two control tokens on one channel means the stream ended twice. Single-shot EOF today, live the moment a pipeline is reused for a second input. **Consequence to hold onto:** a lossless fanout makes join depth a correctness precondition — one branch can now run ahead of another only by the slower branch's buffering, so `kSceneJoinDepth` must exceed the TransNetV2 window. Making the decimator lossless also makes it a backpressure point rather than a relief valve: the source now throttles to the face branch instead of quietly thinning it. Correct under this requirement, but it changes the shape of a loaded run and is **not yet benchmarked**. **Gap:** capacity is still counted in *items*, not bytes, so a crowd frame carrying 60 crops occupies one slot exactly as an empty one does — the memory ceiling the plan asks for is unenforced | +| AR-005 | Align to 112×112 via ArcFace 5-point similarity transform, fitted by **Umeyama least squares over all five points** (as InsightFace does) — never a robust fit, which would discard the landmarks AR-030 reads | SR-002 | High | **Done** — `umeyama_similarity()`.

(1) `scene_decode_fps` defaults to 0 (native): at 12 fps a 100-frame `kWindow` spanned ~8.3 s instead of the ~4 s TransNetV2 was trained on, half-speed motion over twice its temporal context. (2) The boundary dedup window is derived from the cadence the detector was actually fed (`SceneDetectorFunc::dedup_window_sec()`, median observed interval, halved) rather than the literal 0.04 s — one frame at 25 fps, and at 30 fps wider than a frame, so two cuts on consecutive frames merged into one and the loss was invisible: the file simply had fewer boundaries. Derivation checked at 24/25/30 fps and under a seek (UT-003). **Consequence, not a gap:** `scene_threshold` 0.60 was fitted against the 12 fps input and is now certainly wrong — VR-006 re-fits it, and until then boundary recall at native rate is untuned rather than better. Dense decode is the cost driver, so this is not free; `dense_scale` and `scene_stride` remain the reductions that do not run the model off-distribution. **Half-applied until now:** the derived window reached `scenes.json` and nothing else. `SceneBoundaries` — the path that actually feeds `is_scene_boundary` to the tracker — kept the literal 0.04 s under a comment claiming the two views agreed.

Promotion fired on a local accepted-frame count and fell back to a local per-actor plurality whenever the registry had not yet claimed the track — which is the common case, since three accepted frames arrive well before a posterior crosses `ownership_logodds`. So in practice the plurality usually decided, and it could not see the AR-025 discounting it was supposed to defer to.

It immediately caught a live violation — the matcher's no-calibration fallback thresholded raw cosine distance **and fed `max(0, cosine)` into `TrackRegistry::observe`**, whose contract says in terms that it cannot be handed an uncalibrated number by a careless caller. `match_threshold`, `match_ratio` and `match_ratio_ceil` are retired with it, and `TrackGallery`'s `max(0, cosine)` default calibration is now a hard error. One exception recorded, in the calibration's own dedup | +| AR-025 | Per-track Bayesian accumulation in log-odds, with correlated-observation discounting | SR-002 | High | **Done** — log-odds accumulation with correlation discounting owned by the registry, `src/evidence_discount.hpp`.

Baked gallery was already GEMM; the annex now is too — it is a contiguous row-major matrix (`track_gallery.hpp`) whose promoted rows are appended to the engine's resident matrix (`ISimilarityEngine::append_rows`), so one multiply covers baked and promoted references and the host-side cosine loop is gone. CPU path requires OpenBLAS (scalar fallback now opt-in behind `SAE_ALLOW_SCALAR_GEMM`).

Size is `bbox`, not duplicated into a field that would drift. No face is admitted unscored (-1 sentinel), and the degenerate-fit case is now counted and reported rather than silently dropped. **Carried, not consumed** — no discount and no threshold, which is AR-030 and VR-012. Verified UT-137, UT-138 (aligner) and UT-139…UT-141 (dump round-trip, version, sentinel).

Both blur ladders monotone, Gaussian and motion. Three properties recorded on the function for VR-012 rather than corrected here: the contrast invariance is exact in the algebra but bends at the 8-bit quantisation floor (a dim *and* soft crop reads sharper than it is — 148% high at σ 2.5), `BORDER_CONSTANT` fill from a frame-edge face adds a step edge, and the measure conflates focus with intrinsic texture.

Worth recording what the reimplementation was hiding: `build_minimal` rebuilt windows in Python from per-frame annotations, which never consult the registry, so it kept producing plausible output while registry-based presence in replay was returning **nothing at all**.

No sweep could vary them. They are in `Config` with CLI flags now, so this row can be run. `ownership_logodds` is the one to start with: below it a track makes **no presence claim at all**, so it decides whether an actor is reported rather than how confidently | +| VR-008 | Gallery scaling benchmark — throughput vs gallery size | PR-002 | Medium | Planned | +| VR-009 | Verify accumulated posteriors are calibrated against held-out tracks | PR-002 | High | Planned | +| VR-010 | Dump provenance attributes — embedder model, detector settings, `dense_scale`, `scene_detect`, sample rate | PR-002 | **High** | **Done** — `DumpProvenance` in `embedding_dump_node.hpp`, written as root attributes and read back tolerantly. Every field is optional so a pre-VR-010 dump reads as *unknown* rather than as a default; a silently-defaulted `detector_conf` is exactly the fabricated provenance this exists to prevent.

The three per-node factories are replaced by one `add_pipeline` that mirrors `main.cpp`'s construction order — the ordering constraint (matcher fits the calibration, registry needs a discounter from it, tracker needs both, sink needs the claims) is what a factory-per-node API could not express, and is why the tracker factory kept building `FaceTrackerFunc{cfg}` against a signature that had stopped existing. `build_minimal` and `anneal_sec` are gone.

The `runtime/2` anchor confirmed through real head-trimmed files (a `delta` trim moves the window by `delta/2`). The one soft spot is **tier labelling, not accuracy**: the score falls with sub-frame misalignment (0.94–0.99 near a frame boundary, 0.69–0.73 at half a frame), so 27/40 correct alignments were demoted to `loose`. ±1 frame of slack in the *score* fixes it — measured, all 40 back to `audio` (min 0.906), false matches unmoved at 0.12–0.16, costing 81 ms of the budget | +| VR-015 | Per-node cost and bottleneck attribution for a run — where the time actually goes | PR-004 | High | **Done** — `--benchmark ` on `scene_analyze`; `src/benchmark.hpp`.

FPI 0.0% at every scale. Ceiling is cross-view, not resolution | +| VR-016 | **Cut-detection cadence study** — is `cut_threshold` 0.70 meaningful at the rate `camera_pos` is actually fed? | PR-002 | Medium | **Planned.** The histogram cut detector is the one always-on signal with no recorded provenance, and its input rate is not the rate it was fitted at. With `--scene-detect` off, `camera_pos` sits downstream of a source already decimated to `sample_fps`, so at the 1.0 default it compares frames **one second apart** — inside a single shot those differ enormously, and 0.70 correlation is a low bar to clear. With `--scene-detect` on it sees native-rate frames instead, so the same constant means two different things depending on an unrelated flag. This is AR-011's argument ("every model gets the input it was trained for") applied to a non-neural detector, and it matters because `is_cut` drives `track_alpha` to 0 and clears every expansion buffer. Cheap first measurement: run `camera_pos` over a `hero/` clip at 1/2/5 fps and compare cut counts against `tests/fixtures/dumps/scene_bounds.json`. The committed 5 fps dump shows 2.6% of frames flagged; nobody has measured 1 fps | +| VR-017 | **Vote-lag study** — how often does the matcher fall more than `track_extinction_sec` behind the tracker on real content? | PR-002 | **High** | **Planned.** Channel depth is a correctness parameter between `face_tracker` and `identity_matcher`, and the constraint runs opposite to the scene join's: there `kSceneJoinDepth` must EXCEED the TransNetV2 window, here the depth must be UNDER `track_extinction_sec × sample_fps`. Backpressure is what makes it bite — it is working, and a lossless channel converts depth into lag by design. Both nodes are 16 deep in `main.cpp`, which at the default `sample_fps` 1.0 is ~16 s of lag against a 5 s window, so `scene_analyze` can drop identity votes and until now said nothing. It now reports `dropped_votes` at shutdown; this row is the measurement that decides whether that should be fatal, and whether the right fix is bounding the depth or removing the coupling (reap on the matcher's clock rather than the tracker's, so a vote cannot be late by construction) | + +--- + +## Verification strategy + +**CI runs on an Intel N100 with no discrete GPU.** That is a hard constraint on +how each requirement can be verified, and it shapes the test design rather than +merely limiting it. + +Four tiers, in decreasing order of preference: + +| Tier | Runs in CI | What it covers | +|---|---|---| +| **T1 — Functor unit** | Yes | A KPN node's `operator()` driven directly with hand-built inputs | +| **T2 — Replay** | Yes | The composed pipeline driven from an HDF5 fixture — no GPU, no video | +| **T3 — CPU inference** | Yes, slowly | ORT CPU provider over a handful of frames; smoke tests only | +| **T4 — GPU** | **No** | Throughput, TRT engines, large-gallery GEMM | + +### T1 is the primary tier, and KPN is why + +**Node functors are plain callable structs, constructed independently of the +network that wraps them** (`main.cpp:186-207` builds them as stack objects; +`ObjectNode` merely adapts them). So a node is testable by constructing it and +calling `operator()` — no channels, no threads, no network, no fixture. + +This is already the established pattern, not a proposal: +`tests/test_face_tracker.cpp` "drives the node's `operator()` with hand-built +`EmbeddedSceneFrame`s and inspects the emitted `track_ids`", and does so +"pure, GPU-free, model-free". + +The consequence is that most of the redesign is verifiable **without any +fixture at all**: construct exactly the awkward state — a belief swap, two live +tracks converging on one actor, a film ending mid-track, a gap one frame under +the timeout — rather than hunting for a clip that happens to exhibit it. + +Four hazards this removes outright: + +- **No fixture-provenance risk** for these tests — the inputs are synthetic and + explicit. +- **No "fixture must be replayed from frame 0"** concern — state is constructed + directly. +- **No cross-test state leakage** (e.g. a tracker's `next_id_` persisting) — each + test constructs a fresh functor. +- **No replay-harness nondeterminism** — no channels, so no EOF-tail heuristics + or silent drops. + +It also means **a dead upstream producer does not block testing a downstream +consumer.** `is_scene_boundary` currently has no producer (see AR-010), which +would make a *replay* test of the frame-dependent `track_alpha` pass vacuously — +but a T1 test simply constructs a frame with `is_scene_boundary = true` and +asserts the weighting changes. The producer gap is a pipeline defect to fix, not +a verification blocker. + +### T2 covers what T1 cannot + +Replay remains necessary for **composition** — that the nodes wired together +behave as the sum of their parts — and for realistic data at scale, which +synthetic inputs cannot honestly imitate.

That was built for the optimizer; it doubles as +CI, which is a strong argument for keeping the schema honest and for replay +driving the *real* nodes rather than a reimplementation (VR-002). + +**Fixtures and studies are generated locally**, on the development machine where +the models, galleries and media already exist.

Its +benchmark (VR-008) should run on a schedule rather than on demand. + +### CI never calls a model + +**Not "should not" — cannot.** The N100 has no GPU, and even the ONNX Runtime CPU +provider is impractical: a measured run of the embedder on this hardware sits at +~930 ms per frame, so a 77 s clip at 5 fps would take roughly six minutes of +inference alone. Every model invocation therefore happens **locally, ahead of +time**, and CI consumes the result as data. + +This is what makes the T1/T2 split load-bearing rather than a preference: T1 and +T2 are the only tiers that can exist in CI at all. + +### Fixture corpus — `hero/` + +Five clips of **SuperHero (1952)**, ~77 s each, 480×360, 30 fps, 42 MB total. + +Public domain, and that is the reason to use it rather than a convenience: +**derived fixtures — dumps, crops, golden outputs — can be committed without the +rights question that rules out sharing gallery data (SR-005).** A fixture cut +from a copyrighted title could not live in the repository at all. + +Two properties to design around rather than discover: + +- **480×360 means small faces.** At this resolution a face is often 40–80 px, so + the AR-002 minimum of 40 px (original resolution) sits at the very bottom of + that range: the filter is close to binding, and anything shot wider is lost. + Fixture generation must set `--min-face-px` explicitly and record it, or the + dumps will be sparse for reasons unrelated to what is being tested. +- **77 s is short.** At 1 fps that is 77 frames — too thin to exercise an + extinction window measured in tens of seconds.

Substituting +`detector_conf = 0.5` for a dump that does not say so manufactures the provenance +the requirement exists to prevent — per `docs/requirements.md`, *"a fixture whose +provenance is unknown is worse than no fixture, because it will be trusted."* +The committed `tests/fixtures/dumps/*.h5` predate VR-010 and carry none of these +attributes; re-dump to bind them, as with GR-004. + +## Embedding input quality (AR-028) — and why this one bumps the version + +`sharpness` and `alignment_residual` are two of the three AR-028 quality axes, +written beside the embedding they describe. **The third axis, size, is already +here**: it is `bbox`, scaled by `bbox_upscale` to reach the original resolution +AR-002 thresholds in. It is not duplicated into a third column, because that +would put the same quantity in two coordinate spaces inside one file — the trap +the `bbox_upscale` note below records — and the copy is the one that drifts. + +The vector is **carried, not consumed**. Nothing in the pipeline thresholds or +discounts on it yet; VR-012 locates the knees from these columns, which is only +possible if they were recorded at inference. A study cannot recover how sharp a +face was from an embedding, any more than it can recover which model produced it. + +**This is the change that bumps `schema_version` to 2**, where VR-010's +attributes did not. The rule is unchanged — a bump is for the *datasets* — and +so is the reason behind it. Readers are fine either way: `replay.py` and +`test_replay_fixtures.cpp` take these datasets by name with an existence check, +so a v1 dump still replays and loses only what it never had. The version exists +for a *consumer of the quality vector*, which otherwise cannot tell **"this +film's faces were never scored"** from **"this film's faces scored zero"** — +sharpness 0 is a real reading, meaning a featureless crop. That is the same +distinction `scene_detect` exists to make, and it is equally unrecoverable from +the arrays. + +A v1 dump reports the vector as **unknown, never as a default** — `load_frames` +omits the keys rather than filling zeros, and the C++ side leaves the +`DetectedFace` fields at their -1 "unscored" sentinel. Re-dump to acquire it; +there is no migration, for the same reason GR-004 has none. + +> The committed `tests/fixtures/dumps/*.h5` are v1 and carry no quality vector. +> Re-dumping needs a GPU host (`scripts/make_fixtures.sh`), so until that runs, +> anything driven from the fixtures sees the sentinel. + +## Model binding (GR-004) + +`embedder_model` / `embedder_sha256` record which embedder produced every vector +in `faces/embedding`. A replay has no live embedder, so **the dump is the embedder +as far as the gallery is concerned**: `replay.py` checks these two attributes +against the gallery's own `/embedder` stamp and refuses to run on a mismatch, +naming both sides. Cross-model cosines are meaningless but look plausible. + +The attributes are additive, not a format break — `schema_version` stays 1. Dumps +written before GR-004 simply lack them, which reports as *unverifiable* (a loud +warning, or a hard error under `SAE_REQUIRE_GALLERY_STAMP=1`) rather than as a +pass. Re-dump to bind an old dump; there is no in-place migration, because unlike +a gallery nobody can assert after the fact which model produced a vector. + +## Coordinate space — `bbox`, `landmarks`, `bbox_upscale` + +`bbox` and `landmarks` are in **decoded-frame pixels**: exactly the numbers SCRFD +produced, untransformed. To reach original video pixels, multiply by +`bbox_upscale`. With `dense_scale == 1` (the default, and every committed +fixture) `bbox_upscale == 1` and the two spaces coincide. + +> Earlier revisions of this document claimed the upscale was applied at dump time. +> It never was. `embedding_dump_node.hpp` writes `f.bbox` raw; the upscale lives +> in `identity_matcher_node.hpp`, which is *downstream* of the dump tap. The +> claim was harmless only because `dense_scale` was 1 in practice. + +The fix is to record the factor rather than to apply it, because the dump's whole +contract is to be a **faithful tap** at the `EmbeddedSceneFrame` channel — VR-002 +requires replay to drive the real nodes, and a replay is only equivalent to the +live run if the tracker is fed the geometry the live tracker saw. Rescaling at +the tap would break that: the replayed tracker would associate on boxes the live +one never received. Two further reasons: + +- The matcher's upscale is applied to `bbox` **only**, not to `landmarks`. + Pre-multiplying at the tap would leave the two arrays in different coordinate + spaces inside one file — a worse trap than the one being fixed. +- Pre-multiplying is lossy in the sense that matters: a dump that had been + upscaled would be indistinguishable from one taken at `dense_scale == 1`, so + you would have to record `bbox_upscale` anyway to know which you were holding. + ## Invariants - `embedding` rows are unit-norm (cosine == dot product against the gallery). - `face_offset[0] == 0`; `face_offset[i+1] == face_offset[i] + face_count[i]`. -- `bbox` is already mapped to original resolution (bbox_upscale applied at dump time), - matching what the identity matcher would emit. +- `bbox` and `landmarks` share one coordinate space; `bbox_upscale` maps both to + original resolution (see above). - A frame with no faces has `face_count == 0` (still gets a row, so timestamps stay dense). - EOF sentinel frames are NOT written. +- v2 onward: `sharpness` and `alignment_residual` are `[N]`, parallel to + `confidence`, so face *i*'s quality indexes with the same slice as its + embedding. Both are `>= 0` for any face the aligner admitted; a negative value + means unscored and must never be read as a quality. diff --git a/scripts/optimizer/dump_error_frames.py b/scripts/optimizer/dump_error_frames.py index 2892345..fb70470 100644 --- a/scripts/optimizer/dump_error_frames.py +++ b/scripts/optimizer/dump_error_frames.py @@ -121,23 +121,44 @@ def load_raw_annotations(raw_path: str): return by_second -def draw_annotations(frame_path: Path, actors: list): +def _name_key(name: str) -> str: + """Normalised match key, mirroring identity.py's name: fallback.""" + return "name:" + "".join(ch for ch in name.lower() if ch.isalnum() or ch == " ").strip() + + +def draw_annotations(frame_path: Path, actors: list, fp_keys=None, fn_names=None): + """Draw GT-aware boxes: GREEN = true positive (named actor X-Ray also has in + this scene), RED = false positive (named actor NOT in the scene → the real + error), ORANGE = unknown detection.

Degrading both sides would measure +something the pipeline never does. + +What this deliberately does NOT measure +--------------------------------------- +The cosine between the size-S embedding and the native embedding of the *same* +image. That is embedding *drift*, and it answers the wrong question: an embedding +can drift a long way and stay perfectly separable, or drift a little in a +direction that destroys separation. What matters is the decision the pipeline +makes — probe against a competing gallery — so that is what is recorded. + +CAVEAT — FPI IS RELATIVE, NOT ABSOLUTE +-------------------------------------- +False positives grow with the number of actors competing for the match. A +~100-actor gallery therefore *understates* the false-positive rate against a +production library of thousands. Read the FPI column as a relative curve across +sizes ("FPI is 4x worse at 32 px than at 64 px"), never as the rate you would see +in production. Re-run with `--actors` at production scale before setting a +threshold from an absolute FPI number. + +Decision rule +------------- +Per the repo invariant (CLAUDE.md: "always use the calibrated probability, never a +raw cosine"), identification goes through the same path as `identity_matcher_node`: +per-actor best-of-N cosine -> Platt sigmoid P(match) = sigma(a*sim + b + log-prior) +-> accept if P > `prob_threshold`. The sigmoid is fitted here by the same +histogram/gradient-descent procedure as `src/gallery/gallery_calibration.hpp`, +over the native gallery embeddings only (held-out probes are excluded, so the +calibration cannot see the images it will be scored on). + +How this runs +------------- +Through the `sae_embed` bindings, which expose the shipped C++ stages directly: +`detect()`, `align_face()`, `embed_crops()` and `GalleryCalibration`. Nothing +here re-implements detection, the ArcFace warp, the embedder or the Platt fit. + +That matters most for the calibration. A second copy of the sigmoid is exactly +where "always the calibrated probability, never a raw cosine" (AR-024) gets +broken without anyone noticing, because the copy keeps returning plausible +numbers after the original has moved. Scoring through the binding makes the rule +structural instead of remembered. + +The backend is whichever was compiled in. Under `SAE_INFERENCE_BACKEND=ORT` +that is the reference fp32 path, which loads the .onnx directly. A TensorRT fp16 +build is a *different realisation* of the same model and its embeddings are +measurably not the same vectors: on LVFace-B_Glint360K the stored TRT-fp16 gallery +agrees with an fp32 recompute of the same mugshot at only ~0.85 cosine, while +same-actor/different-actor separation is essentially unchanged (d' 5.3 vs 5.7). +Nothing here is invalidated by that — gallery and probes go through one session, +so the comparison is internally consistent — but the two embedding spaces are not +interchangeable, and `--verify-against ` will show ~0.85, not ~1.0, +against a TRT-built gallery. It reports the separation of both sets alongside the +agreement so the two causes are distinguishable: a broken port collapses +separation, a different backend does not. + +Secondary output (VR-005): running the sweep per `--arcface` model shows whether +`min_face_px` should be one constant at all, or should scale with the embedder — +which matters because the model is a build-time choice (GR-004). + +Usage +----- + python scripts/validation/min_face_size.py \ + --images images \ + --gallery gallery_lvface.h5 \ + --arcface models/LVFace-B_Glint360K.onnx \ + --actors 100 --seed 0 \ + --out experiments/results/vr005_min_face_size + +Writes .csv, .json and .png (plus .per_probe.csv with +--per-probe). +""" +from __future__ import annotations + +import argparse +import csv +import json +import random +import re +import sys +import time +from pathlib import Path + +REPO = Path(__file__).resolve().parent.parent.parent +sys.path.insert(0, str(REPO / "scripts")) +def _find_sae_embed() -> Path | None: + """Locate the built sae_embed module. + + A git worktree has no build tree of its own, so fall back to the main + checkout via the shared git dir — otherwise running this study from a + feature worktree cannot find the bindings it now depends on. + """ + roots = [REPO] + try: + import subprocess + common = subprocess.run(["git", "-C", str(REPO), "rev-parse", + "--path-format=absolute", "--git-common-dir"], + capture_output=True, text=True, check=True).stdout.strip() + if common: + roots.append(Path(common).parent) + except Exception: + pass + for root in roots: + for b in ("build-ort", "build"): + if list((root / b).glob("sae_embed*.so")): + return root / b + return None + + +_SAE_BUILD = _find_sae_embed() +if _SAE_BUILD is None: + sys.exit("cannot find the built sae_embed module — build it with\n" + " cmake --build build-ort --target sae_embed") +sys.path.insert(0, str(_SAE_BUILD)) + +# Before cv2: OpenCV's DNN module loads the system libonnxruntime, which then +# shadows the one sae_embed links against and the import fails on a missing +# symbol version.

VR-012 has to locate one knee across films whose grading differs by +// more than their focus does; an uncalibrated measure would put the knee in a +// different place per film, which is the AR-024 failure in another metric. +// - **Measured on the aligned crop, so size cannot leak in.** The destination +// frame is fixed at 112×112 (AR-002 owns size, and double-counting it here +// would make every small face read as blurred). What the ratio reports is the +// detail actually present in the embedder's input — so a small sharp face can +// and does outscore a large soft one. That is the claim; it is *not* a claim +// of invariance to source resolution, because a 40 px face warped up to 112 +// genuinely carries less detail, and hiding that would defeat the point. +// +// Frequency-domain reading of why the blur ladder is monotone: with +// Var(∇²I) = ∫|ω|⁴|F(ω)|² and Var(I) = ∫|F(ω)|², the ratio is E[|ω|⁴] under the +// image's own spectral measure. Gaussian blur multiplies that measure by +// e^{-σ²|ω|²}, concentrating it at low |ω|, so the expectation falls strictly +// with σ. It is a property of the construction, not a fitted behaviour. +// +// **Three known hazards, for VR-012 to check rather than for a threshold to +// absorb.** All are recorded here because they are properties of the measure, +// visible in the dumped distribution, and neither should be papered over by a +// correction chosen before that distribution has been looked at. +// +// 1. **Border fill.** `align_face` warps with BORDER_CONSTANT, so a face +// crossing the frame edge brings a hard black step into the crop, and a +// step edge is high-frequency. The normalisation blunts it — the fill +// inflates Var(I) as well as Var(∇²I) — but does not remove it, so +// heavily-cropped faces may read sharper than they are. The fix is either a +// validity mask or a different border mode, and the second changes what the +// embedder is fed (AR-011). +// +// 2. **The contrast invariance is exact in the algebra and approximate in +// 8 bits.** Scaling I by α cancels exactly; what does not cancel is the +// quantisation floor of a stored crop, which is broadband and so lands in +// the numerator. It matters only where there is little signal left to +// compete with it: on the AR-029 test texture a half-contrast copy reads +// 0.9% high when sharp, 24% high at sigma 1.2 and 148% high at sigma 2.5. +// A crop that is both **dim and soft therefore reads sharper than it is** — +// the low corner of the axis, and the corner VR-012 must put a knee in. +// +// 3. **It reports where the energy sits, not how much there is.** A crop whose +// energy is *already* concentrated at high frequency — dense film grain, +// a face against foliage — loses numerator and denominator together under +// blur, so the ratio moves less than the damage does. Measured on a +// flat-spectrum synthetic, an anisotropic (motion) smear even makes it rise, +// because the surviving perpendicular detail really is as fine as before. +// Natural crops have the low-frequency mass that keeps the denominator +// steady, and on those both ladders fall (see the AR-029 tests, which use a +// 1/f texture for exactly this reason). The same property means the axis +// conflates focus with intrinsic texture — a bearded face outscores a smooth +// one at equal focus — which is true of every no-reference sharpness measure +// and is why AR-028 carries the number instead of thresholding on it. +inline float crop_sharpness(const cv::Mat& crop) { + if (crop.empty()) return -1.f; + + cv::Mat gray; + if (crop.channels() == 3) cv::cvtColor(crop, gray, cv::COLOR_BGR2GRAY); + else gray = crop; + + cv::Mat lap; + cv::Laplacian(gray, lap, CV_32F, 3); + + cv::Scalar mean_i, sd_i, mean_l, sd_l; + cv::meanStdDev(gray, mean_i, sd_i); + cv::meanStdDev(lap, mean_l, sd_l); + + const double var_i = sd_i[0] * sd_i[0]; + // A flat crop has no detail to be sharp or soft about, and the ratio is 0/0. + // Zero is the honest answer and keeps the axis finite; -1 would claim the + // face was never scored, which is a different fact. + if (var_i < 1e-6) return 0.f; + + return static_cast((sd_l[0] * sd_l[0]) / var_i); +} + // ── enhance_for_retry ──────────────────────────────────────────────────────── // Used when initial face detection finds nothing.
