Follow-up to the calibration deadlock fix. With the status gate unstuck,
maybe_feed_calibration reached feed_calibration, but a real ESP32 HT40 node
streams 128-wide amplitude frames while the single-link FieldModel is the
canonical 56-tone grid. LinkStats::update returned DimensionMismatch,
feed_calibration bubbled it, and maybe_feed_calibration swallowed it at debug
level — so frame_count stayed pinned at 0 on live hardware (presence/vitals,
which read the global history, were unaffected).
Resample each frame onto the model's canonical 56-tone grid via
HardwareNormalizer::resample_to_canonical before feeding — the same length-only
canonicalization the multistatic fusion path uses (#1170).
Pinned by maybe_feed_calibration_resamples_wide_frames_and_accumulates
(128-wide -> Collecting + count 1). sensing-server bin: 173 passed, 0 failed.

POST /api/v1/calibration/start created the FieldModel in Uncalibrated, but
field_bridge::maybe_feed_calibration only fed frames while already Collecting
— and the only thing that sets Collecting is feed_calibration on its first
fed frame. The two gates deadlocked: no first frame was ever fed, so
calibration_frame_count stayed 0 and status never left Uncalibrated. Observed
live on a streaming ESP32 node as {"status":"Uncalibrated","frame_count":0}
that never advanced.
- field_bridge::maybe_feed_calibration: feed while Uncalibrated | Collecting
so the first frame flips the model to Collecting and the count advances.
- calibration_stop: return structured {success:false, frame_count,
frames_needed} instead of an opaque 500 when finalized with too few frames.
- FieldModel::min_calibration_frames() accessor for the guard above.
- Regression test: maybe_feed_calibration_advances_uncalibrated_to_collecting.
Presence/motion/vitals were unaffected (separate auto rolling baseline).

field_bridge::occupancy_or_fallback returned FieldModel::estimate_occupancy
unbounded (internal ceiling 10), while the perturbation fallback below it
and score_to_person_count both cap at 3 ("1-3 for single ESP32"). On noisy
or under-calibrated CSI the eigenvalue count inflated → "10 persons when 1
present" (#894, seen when --model fails to load → heuristic mode). Bound the
eigenvalue path to a shared MAX_SINGLE_LINK_OCCUPANCY const (3) so every
single-link estimator agrees. Genuine higher counts come from the
multistatic fusion path. Build clean, field_bridge tests pass.
The Rust port lived two directories deep (rust-port/wifi-densepose-rs/)
without any sibling under rust-port/ that warranted the extra level.
Move the whole workspace up to v2/ to match v1/ (Python) at the same
depth and shorten every cd / build command across the repo.
git mv preserves history for all tracked files. 60 files updated for
path references (CI workflows, ADRs, docs, scripts, READMEs, internal
.claude-flow state). Two manual fixes for relative-cd paths in
CLAUDE.md and ADR-043 that became wrong after the depth change
(cd ../.. → cd ..).
Validated:
- cargo check --workspace --no-default-features → clean (after target/
nuke; the gitignored target/ was carried by the OS rename and had
hard-coded old paths in build scripts)
- cargo test --workspace --no-default-features → 1,539 passed, 0 failed,
8 ignored (same totals as pre-rename)
- ESP32-S3 on COM7 → still streaming live CSI (cb #40300, RSSI -64 dBm)
After-merge follow-up: contributors should `rm -rf v2/target` once and
let cargo regenerate from the new path.
