root a81291e38c proof harness Phase A: scaffolding + canary case green
Per docs/TEST_PROOF_SCOPE.md, building the claims-verification tier
above the smoke chain. This commit lays the scaffolding and proves
the orchestrator end-to-end with one canary case (00_health).

What landed:

  tests/proof/
    README.md             how to read a report, layout, modes
    claims.yaml           24 claims enumerated (GOLAKE-001..100)
    run_proof.sh          orchestrator with --mode {contract|integration|performance}
                          and --no-bootstrap / --regenerate-{rankings,baseline}
    lib/
      env.sh              service URLs, report dir, mode, git context
      http.sh             curl wrappers writing per-probe JSON + body + headers
      assert.sh           proof_assert_{eq,ne,contains,lt,gt,status,json_eq} +
                          proof_skip — each emits one JSONL record per call
      metrics.sh          start/stop timers, value capture, RSS sampling,
                          percentile compute (for Phase D)
    cases/
      00_health.sh        canary — gateway + 6 services /health → 200,
                          body identifies service, latency < 500ms (21 assertions)
    fixtures/
      csv/workers.csv     spec's 5-row deterministic CSV
      text/docs.txt       4 deterministic vector docs
      expected/queries.json  expected results for the 5 SQL assertions

Wired into the task runner:

  just proof contract       # canary only this commit
  just proof integration    # Phase C
  just proof performance    # Phase D

.gitignore: /tests/proof/reports/* with !.gitkeep — same pattern as
reports/scrum/_evidence/. Per-run output is a runtime artifact.

Specs landed alongside (J's drops):
  docs/TEST_PROOF_SCOPE.md           the harness contract this implements
  docs/CLAUDE_REFACTOR_GUARDRAILS.md process discipline this harness obeys

Verified end-to-end (cached binaries):
  just proof contract        wall < 2s, 21 pass / 0 fail / 0 skip
  just verify                wall 31s, vet + test + 9 smokes still green

Two bugs fixed during canary run, both in run_proof.sh aggregation:
- grep -c exits 1 on zero matches; the `|| echo 0` form concatenated
  "0\n0" and broke jq --argjson + integer comparison. Fixed via a
  _count helper that captures count-or-zero cleanly.
- per-case table iterated case scripts (filename-based) but cases
  write evidence under CASE_ID. Switched to JSONL-file iteration so
  multi-case scripts work and the mapping is faithful.

Phase B (contract cases) lands next: 05_embedding, 06_vector_add,
08_gateway_contracts, 09_failure_modes. Each sourcing the same lib
helpers and writing to the same report shape.
