chore(repo): move v1/ → archive/v1/ + add archive/README.md (#430)
The Rust port at v2/ has been the primary codebase since the rename
in #427. The Python implementation at v1/ is no longer the active
target; the only load-bearing path is the deterministic proof bundle
at v1/data/proof/ (per ADR-011 / ADR-028 witness verification).

Move the whole Python tree into archive/v1/ and document the policy
in archive/README.md: no new features, bug fixes only when they affect
a still-load-bearing path (currently just the proof), CI continues to
verify the proof on every push and PR.

Path references updated in 26 files via path-pattern sed (only
matches v1/<known-child> patterns, never bare v1 or API URLs like
/api/v1/). Two double-prefix typos (archive/archive/v1/) caught and
hand-fixed in verify-pipeline.yml and ADR-011.

Validated:
- Python proof verify.py imports cleanly at archive/v1/data/proof/
  (numpy/scipy still required; CI installs requirements-lock.txt
  from archive/v1/ now)
- cargo test --workspace --no-default-features → 1,539 passed,
  0 failed, 8 ignored (unaffected by Python tree relocation)
- ESP32-S3 on COM7 untouched (no firmware paths changed)

After-merge: contributors should re-run any local `python v1/...`
commands as `python archive/v1/...` (CLAUDE.md and CHANGELOG already
updated).

Archive

Frozen, no-longer-active components of RuView preserved for historical reference, reproducibility, and load-bearing legacy paths the active codebase still depends on.

What lives here

Path What it is Why it's archived Still load-bearing?
v1/ Original Python implementation of RuView (CSI processing, hardware adapters, services, FastAPI) Superseded by the Rust workspace at v2/; ~810× slower in benchmarks. Kept rather than deleted because the deterministic proof bundle (v1/data/proof/) is part of the pre-merge witness verification process per ADR-011 / ADR-028. Yes — for the proof bundle only. Active code lives in v2/.

What "archived" means

  • Do not add new features here. New work goes in v2/.
  • Do not refactor or modernize the archived code beyond what is strictly necessary to keep the load-bearing paths working. The Python proof bundle is intentionally frozen so that its SHA-256 reproducibility holds across releases (per ADR-028's witness verification requirement).
  • Bug fixes inside archived code are allowed when the bug affects a still-load-bearing path (currently: only the Python proof). All other "bugs" in archived code are out-of-scope — they are part of the historical record and any fix would unnecessarily churn the witness hashes.
  • CI continues to verify the load-bearing paths. .github/workflows/verify-pipeline.yml runs the Python proof on every push and PR; if you change anything inside archive/v1/src/ or archive/v1/data/proof/, expect the determinism check to flag it.

Quick reference for the load-bearing paths

# Run the deterministic Python proof (must print VERDICT: PASS)
python archive/v1/data/proof/verify.py

# Regenerate the expected hash (only if numpy/scipy version legitimately changed)
python archive/v1/data/proof/verify.py --generate-hash

# Run the full Python test suite (legacy, still maintained)
cd archive/v1&& python -m pytest tests/ -x -q

Why we keep v1/ rather than delete it

  1. Trust kill-switch. The proof at v1/data/proof/verify.py feeds a known reference signal through the full pipeline and hashes the output. If the active code's behavior drifts, the hash changes and CI fails. This is what stops accidental regression in the science layer of the codebase.

  2. Witness verification. ADR-028's witness-bundle process bundles the proof, the rust workspace test results, and firmware hashes into a tarball recipients can self-verify. Removing v1 would break that chain.

  3. Historical reference. ADR-011 documents the "no mocks in production code" decision; the original violations and their fixes live in this Python codebase. The ADRs reference these paths.

If the time comes to retire the proof bundle (e.g., a Rust port of the proof exists and the Python version is no longer canonical), the right move is a single follow-up that simultaneously: ports the witness-bundle process, updates verify-pipeline.yml, and either deletes archive/v1/ or moves it to a separate read-only repository. That decision belongs in its own ADR.
