v0.3.20

Fixed

• AGENTS.md private paths — v0.3.19 published AGENTS.md with private
  local paths (absolute home directory, VMware mount). Sanitized: removed
  all absolute home paths, mount references, and username. Database
  name corrected from stale capture.db to umans-gate.db.
• docs/ARCHITECTURE.md — context_management injection condition
  corrected from "anthropic-version is 2023-06-01" to actual gate:
  stampClaudeCode && !isOpenAi && thinking enabled. Worker pipeline
  description corrected from "offloads writes" to "exists but disabled".
• README.md — CONCURRENCY_HARD_CAP/SOFT_LIMIT descriptions
  corrected from "non-configurable" to "auto-derived from /v1/usage".
• docs/proxy-modifications.md — 4 nonexistent constants removed,
  HOP set path fixed (helpers.ts → shared/http-headers.ts), 15+ stale
  line number references updated, warmer_path corrected to hardcoded.
• ROADMAP.md — Current State version stamp fixed (v0.3.18 → v0.3.19).

Changed

• ADR-0006 — model-policy.ts references corrected to stamp-catalog.ts.
• ADR-0008 — added superseded-by note pointing to ADR-0011.
• ADR-0002 — status updated from "Proposed" to "Accepted"; duplicated
  paragraph removed.
• ADR-0004 — status updated from "Proposed" to "Accepted".
• ADR-0013 — status updated from "proposed" to "Accepted".
• ADR-0014 — "Applies to" stamp updated from v0.3.18+ to v0.3.19+.
• ADR-0005 — handoff.ts line count prediction corrected from ~500 to ~638.

Added

• scripts/scan-private-info.sh — CI gate that blocks absolute home
  paths, VMware mount paths, and usernames from tracked files. Runs on
  every PR/push and pre-release.
