  • v0.2.0

    285f732c · Merge branch 'feat/v0.2.0-schema-and-throughput' into 'main' ·
    Release: tach v0.2.0 
    tach v0.2.0

Breaking schema bump for collection.json (1.0.0 -> 2.0.0), new
derived aggregate fields, and a vulnerability throughput collection
stage.

Highlights:
- Breaking: collection.json schema_version 2.0.0.
- Breaking: mr_authors becomes a compact summary object
  (active_authors / total_mrs / top_share / percentiles); the
  per-author row array is no longer emitted.
- Added: per-month failure_rate plus aggregate
  avg_pipeline_failure_rate + pipeline_failure_rate_trend_pct.
- Added: mrs_per_active_user_per_month derived field.
- Added: vulnerability throughput collection (per-month
  vulns_detected / vulns_resolved / vuln_mttr_days, plus
  aggregates).
- Removed: avg_critical_vulns_per_month (identical to
  avg_vulns_detected_per_month by construction).
- CI: container_scanning needs container-build marked optional.

  • v0.1.1

    f5a34735 · Merge branch 'feat/v0.1.1-ux-ship-blockers' into 'main' ·
    Release: tach v0.1.1 
    v0.1.1

UX ship-blockers, hardening, and refactor.

- Fast-fail preflight probe (--preflight-timeout) replaces 2-minute retry
  ladders on wrong or unreachable URLs
- Partial runs render a PARTIAL banner and UNKNOWN zones instead of a
  misleading RED report; Active-users and MR-authors counts annotate
  (unknown) when their stage did not complete
- --ca-bundle / SSL_CERT_FILE for instances fronted by an internal CA
- --token-file for environments that forbid secrets in environment vars;
  0600-or-stricter enforced on Unix
- Output files (collection.json, health-report.*, monthly.csv) written 0600
- Docker image sets WORKDIR /tach-data, chowns for UID 1001, and defaults
  --output so bare docker run + bind-mount works first try
- run and collect share a single CLI setup path
- Dead checkpoint.json write path removed
