Thomas Ales [M S E] 2937c017a7 Merge the Documents/sras-viewer working copy into this repo
The two clones had diverged from origin/main (191d1b8) and both had
grown uncommitted work. This merges the other clone's three commits and
reconciles four conflicting files.

Both clones independently grew a feature called "batch export", but they
are different sweeps and both are kept:
- BatchExportWorker (this clone) — every angle x channel of the one open
  file, fixed colorbar per channel, under a new Export menu.
- BatchExportImagesWorker (other clone) — the current view across many
  selected files, process-pooled, under Convert.

Conflict resolutions of note:
- sras_average.py: the other clone's memory-bounded rewrite had silently
  reverted this clone's float32 -> int16 accumulator fix, which exists to
  keep averaged output from landing 1 ADC count off the original tool.
  Kept the rewrite, re-applied the fix, and corrected the two docstrings
  that still claimed float32.
- tests/test_compute.py: kept the other clone's meta["waveforms"] key
  (meta["data"] no longer exists for this fixture and would KeyError)
  and its laser_freq_hz assertions, plus this clone's int16 expectation
  and its dropped subprocess returncode assertions.
- ComputeWorker: row_avg_n and min_freq_mhz were added independently on
  either side; both are now threaded through.
- compute_rf_image's `exact` parameter is gone, removed by the other
  clone's PyFFTW peak-search rewrite. It had no remaining callers.

Verified: 149 passed with a complete dependency set. The failures seen
with this clone's own .venv are a missing scikit-image, which predates
this merge and reproduces identically on the pre-merge commit.

Thomas Ales [M S E] 6976cbf767 Add batch export of DC/RF/Velocity map images
Add Export -> Batch Export Images..., which renders and saves one PNG
per angle for whichever of CH1 (RF), CH3 (DC-A), CH4 (DC-B), and
Velocity the user selects, for the currently open file. Each channel
gets its own fixed min/max colorbar range, entered once in the dialog
and held constant across every exported angle, so the resulting images
are directly comparable to each other instead of each auto-scaling to
its own data (today's live-view default).

BatchExportDialog (sras_viewer.py) collects the output folder, file
prefix, and per-channel checkbox + range, seeded from whatever's
already cached (session DC/FFT caches, or the file's own v7 cache
blocks) so opening the dialog never triggers a fresh compute. Export
runs on a background thread via a new BatchExportWorker
(sras_workers.py), which computes each angle's channel image with the
existing dc_image_mv/compute_rf_image helpers (reusing one FFT per
angle for both RF and Velocity) and renders it with a headless
matplotlib Agg canvas.

Also includes several small correctness/robustness fixes that were
already staged in the working tree: an int16-vs-float32 accumulator
mismatch in sras_average.py's row averaging, a DC4-mask cache reuse and
atomic sidecar write in sras_compute.py, a dc3/dc4 pairing guard in
sras_format.py's v7 cache writer, and matching updates to the
tools/ test fixtures.

Thomas Ales [M S E] c54cce453c Rewrite sras_average.py for v6/v7, memory-bounded for multi-hundred-GB scans
The old tool only understood the legacy uniform-geometry header and had no
bound on peak RAM, making it unusable on the ragged v6/v7 files the scanner
now produces at up to ~560GB. Reads via SrasFile's memmap and writes in
row-chunks sized to a memory budget (SRAS_MEM_BUDGET_MB), stages to .part and
os.replace()s per scan_format.md's atomic-write requirement, always writes
plain v6 (a v7 cache tail is frame-indexed and invalid after averaging), and
divides laser_freq_hz by N so x_axis_mm() stays correct after the X axis gets
spatially binned.

Thomas Ales 00a7afade0 Dedup format layer; public accessors replace private reach-throughs
- SrasFile: _parse_v6 now retains per-angle x_delta and the verbatim
  preamble/background byte spans, and gains public data_offset,
  y_pos_per_angle, and iter_angle_blocks() (which now owns the ragged
  block-offset walk used three separate places before).
- sras_edit_scans: the 70-line re-parse of the v6 header sections
  (_read_v6_sections/_reread_span/_v6_angle_offsets) collapses into a
  _write_v6 that consumes SrasFile directly — verified byte-identical
  round-trip on v6 int8/int16 and legacy files. Eight print-and-exit
  pairs become _die().
- tools/make_test_sras imports the struct layouts from sras_format and
  the rotation matrix from sras_compute instead of re-declaring them
  (byte assembly stays independent of the reader).
- sras_compute: block_mean_2d, pixel_pitch_mm, nominal_delta_deg made
  public (they were GUI-facing); registration_workers() and
  default_max_workers() wrap the remaining private reach-throughs from
  sras_workers.

Thomas Ales 007089dd48 Convert test scripts to pytest; extend the equivalence harness
- pyproject.toml replaces sras_viewer_requirements.txt (same pins) and
  adds a dev extra with pytest.
- tools/test_refactor.py, test_alignment.py, test_gui.py become
  tests/test_compute.py, tests/test_alignment.py, tests/test_gui.py with
  assertions preserved verbatim. test_gui.py stays one ordered
  integration sequence over a shared module-scoped window.
- check_equivalence.py: drop the dead pre-refactor monolith shim (and the
  _compute_angle_alignment alias it consumed), extend the pad sweep to
  (1, 2, 4, 8, 40), add legacy-v4 and big-endian int16 legs (new bps=2
  option in make_test_sras) so the padded FFT path and the >i2 memmap
  path are in the baseline before the FFT rewrite.

Thomas Ales d5028db445 Add scan-editing CLI and alignment tests; extend Manual Alignment correlation
Continues the Manual Alignment work: refines the FFT cross-correlation and
mask handling, adds sras_edit_scans.py (drop/renumber bad angle scans),
tools/test_alignment.py (registration ground-truth suite), and a rotating
test fixture in make_test_sras.py.

Thomas Ales 9a7cc396e7 Bound nested parallelism, make compute cancellable, harden batch pool
Three defects found by testing the parallel paths end to end.

Nested parallelism was unbounded. DcPrecomputeWorker and the alignment
driver both parallelise over angles, and each angle's compute_dc_image
then parallelised over rows again: 14 x 14 threads, and — worse — every
angle sized its chunk against the *whole* memory budget, so worst-case
live buffers were ~13.9 GB against a 1 GB budget. Capping the inner
worker count alone does not fix it; the chunk is still sized against the
full budget. plan_angle_level now hands each angle both max_workers=1
and its share of the budget, which bounds the real file at 1002 MB.

Chunk planning could not produce concurrency at all. _plan_chunks sized
chunk_rows first, and _chunk_rows_for spends whatever budget it is given
— so a single chunk consumed the lot and budget//chunk_bytes came back
as one worker. It now picks the worker count first and sizes the chunk to
it, giving 7-16 workers on the real file instead of 1.

Cancellation was too coarse to shut down. stop() was only checked between
angles, and one angle of the real scan is ~40 s, so closing the window
sat through it and returned with threads still running. should_stop is
now polled per row chunk and closeEvent signals every worker before
waiting: close went from 4.0 s with two live threads to 1.04 s with both
finished. A cancelled ComputeWorker emits None so a half-filled image is
never cached.

Also: BatchCacheWorker no longer reports every file as failed when the
process pool itself dies (unguarded __main__, frozen build, sandbox) —
it retries those files in-process. Batches below 512 MB skip the pool
entirely, since interpreter startup would otherwise make small jobs
slower. cache_file rejects an unknown mode instead of silently treating
it as "fft".

Measured on the real 496 GB scan, angle 3, 32 rows:
  DC   2.94s -> 0.75s   RF  6.10s -> 1.99s   peak RSS 1.40 -> 1.93 GB
Batch convert, 24 files / 1 GB: 4.03s -> 2.36s.
Memory budget defaults to 1024 MB (SRAS_MEM_BUDGET_MB), the measured knee.

Testing: tools/test_refactor.py (70 checks: cache round-trip and block
carry-forward, partial-cache handling, parallel-vs-serial identity,
no-mask path, ROI mask vs full-grid, v2/v3/v4 parsing, sras_average
round-trip incl. remainder handling) and tools/test_gui.py (46 checks
driving the real widgets and workers headlessly). check_equivalence.py
still reports all 167 outputs identical to ed0eba4.

Thomas Ales 95c273dce5 Add test tooling: synthetic .sras generator and equivalence harness
tools/make_test_sras.py writes small v6 files with per-angle-varying
geometry, distinct per-channel calibration, and deterministic waveform
content (predictable FFT peak per pixel, predictable DC mean per pixel).

tools/check_equivalence.py hashes DC/FFT/alignment outputs across
channels, angles, bg-sub, pad factors, and thresholds. It imports from
either the monolith or the split modules, so the same script captures
both sides of a refactor. Hashes canonicalise to native float64 so a
dtype or byte-order change that preserves values is not a false failure.
