+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+## [1.0.0] — 2026-04-05
+
+### Added
+
+- **Layer 4: Contemplative references** — conditional section in
+  `/interaction-report` when flags are elevated (total >= 5 or fatigue >= 2)
+  and `layer4: true`. Points to Miracle of Mind by Sadhguru.
+- **Automated test suite** — 73 cases using `node:test` (zero npm deps):
+  session-start (4), prompt-analyzer (56), tool-tracker (8),
+  session-end (4), privacy canary (1)
+
+### Fixed
+
+- Dependency regex `you understand me` no longer matches "merging" (added `\b`)
+
+### Changed
+
+- CLAUDE.md testing section updated for automated tests
+- Deprecated bash scripts removed (available in git history)
+- All "Known gaps" from v0.4.0 resolved
+
+## [0.4.0] — 2026-04-05
+
+### Changed
+
+- **All hooks migrated from bash+jq to Node.js** — full cross-platform
+  support (macOS, Linux, Windows)
+  - `lib.sh` → `lib.mjs` (shared library, 22 functions)
+  - `session-start.sh` → `session-start.mjs`
+  - `prompt-analyzer.sh` → `prompt-analyzer.mjs` (23 regex patterns)
+  - `tool-tracker.sh` → `tool-tracker.mjs`
+  - `session-end.sh` → `session-end.mjs`
+- hooks.json now invokes `node ...mjs` instead of `bash ...sh`
+- Zero npm dependencies — Node.js stdlib only (`fs`, `path`, `os`)
+- Bash scripts deprecated (kept for reference, marked with DEPRECATED)
+- Dependencies reduced: bash and jq no longer required
+- All documentation updated for Node.js migration
+
+### Fixed
+
+- Data path fallback now matches documented path
+  (`~/.claude/plugins/data/ai-psychosis`)
+- `.claude/` directory added to `.gitignore`
+- Private repo path removed from design brief
+- CONTRIBUTING.md line reference corrected
+- README now links to CONTRIBUTING.md
+- plugin.json includes author, license, repository fields
+
+## [0.3.0] — 2026-04-05
+
+### Added
+
+- **Layer 3: Interaction reports** — `/interaction-report` slash command
+  for aggregated session statistics
+  - Time periods: `weekly` (default), `monthly`, `all`
+  - Overview: session count, avg duration, tool calls, edit ratio
+  - Pattern flags: dependency, escalation, fatigue, validation frequency
+  - Tool usage distribution (top 10)
+  - Daily activity breakdown
+  - Trend comparison vs previous period
+- `commands/interaction-report.md` — pure markdown command, no script
+  dependencies (cross-platform: macOS, Linux, Windows)
+- Layer 3 respects `layer3: true/false` in
+  `.claude/ai-psychosis.local.md` (opt-in, off by default)
+
+### Changed
+
+- README updated with Layer 3 usage instructions
+- Platform compatibility expanded: Layer 3 works on Windows
+- Version bumped to 0.3.0
+
+## [0.2.0] — 2026-04-05
+
+### Added
+
+- **Layer 2: Programmatic pattern detection** — four hooks measuring session
+  time, tool usage, burst patterns, and language flags
+  - `session-start.sh` — daily session count, late-night detection
+  - `prompt-analyzer.sh` — dependency, escalation, fatigue, and
+    validation-seeking pattern flags (prompt text never stored)
+  - `tool-tracker.sh` — event logging, edit ratio, burst detection,
+    progressive alerts with cooldown
+  - `session-end.sh` — session finalization, JSONL record, state cleanup
+- `lib.sh` — shared library with thresholds, state management, cooldown
+  logic, and layer configuration
+- Per-project layer configuration via
+  `.claude/ai-psychosis.local.md`
+- `require_layer()` guard in all hook scripts — layers are opt-in/out
+- MIT LICENSE file
+- `matcher` field in hooks.json for schema compliance
+
+### Changed
+
+- hooks.json now registers 4 events (was 2)
+- `DATA_DIR` fallback hardened to `~/.claude/data/ai-psychosis`
+- README rewritten with architecture diagram, research background,
+  privacy section, threshold reference tables
+- Version bumped to 0.2.0
+
+### Removed
+
+- `periodic-reminder.sh` — replaced by `tool-tracker.sh`
+- `session-awareness.sh` — replaced by `session-start.sh`
+
+## [0.1.0] — 2026-04-04
+
+### Added
+
+- **Layer 1: Behavioral instructions** — `SKILL.md` with 5 rules and 5
+  named patterns (reinforcement loop, scope escalation, narrative
+  crystallization, emotional dependency, session overuse)
+- `periodic-reminder.sh` — re-injects awareness every 25 tool calls
+- `session-awareness.sh` — SessionStart context injection
+- Plugin manifest (`plugin.json`)
+- Design document (`docs/ai-ai-psychosis-brief_1.md`)
+
+## Known gaps
+
+- No CI pipeline
+- Single-user plugin — no multi-user patterns considered
