Full Changelog: v1.2.5...v1.3.0

v1.2.5

Fixes

• mitmproxy crash on git operations (PR #75): github.com added to --ignore-hosts. Large git pack responses (~1.8MB) were crashing mitmproxy silently.
• mitmproxy crash on incomplete Copilot streaming (PR #75): PYTHONOPTIMIZE=1 disables mitmproxy's debug-only @expect assertions that crashed the proxy when the API closed a streaming connection mid-chunk.

v1.2.4

MULTI-001 — Multi-agent claim visibility in compact-prepare

• compact-prepare resume now shows active task claims from other sessions prominently, preventing agents from starting work already owned by another session
• Generic: supports any multi-session runtime via AGENT_CLAIMS_DIR env var or standard locations (~/.myelin/claims, ~/.agent-state/claims)
• constitution-template.md: mandatory 4-step claim protocol (tool-agnostic)
• CLAUDE.md + copilot-instructions.md: no-emoji rule in commit messages

Also includes recent fixes merged by other session: LAUNCHD-ENABLE-001 (launchd bootstrap fix), UPDATE-PATH-001 (subprocess PATH fix), DEP-UPDATE-SERENA-001 (serena 1.6.0), HLITE-B5 improvements.

v1.2.3

Features

• feat(install): Write /myelin:compact + /myelin:constitution for Claude Code (CLAUDE-CMD-001, #59)
  • /myelin:compact — ~/.claude/commands/myelin/compact.md written on install; Bash-only (no MCP SQL dependency); graceful exit 2 with clear message when run outside Copilot CLI context
  • /myelin:constitution — ~/.claude/commands/myelin/constitution.md written on install; runs myelin constitution via managed runtime path
  • installCopilotSkills now accepts claudeCC flag; installs compact-prepare.mjs symlink/copy for Claude users even when Copilot client is not active
  • All 3 slash commands now available in Claude Code: /myelin:init, /myelin:compact, /myelin:constitution

v1.2.2...v1.2.3

v1.2.2

Features

• feat(runtime): Pin Node ≥20 and Python 3.12 via version managers (#56)
  • Added .nvmrc, .node-version (Node 20), .python-version (3.12)
  • MANAGED_PYTHON_VERSION = '3.12' exported from component-manifest.mjs as single source of truth
  • All managed uv venvs now use uv venv --python 3.12 — deterministic across machines and uv versions
  • Per-component override via pythonVersion field (validated)
  • install.sh: sources ~/.nvm/nvm.sh before node check for nvm users
  • install.ps1: detects fnm/nvm-windows and activates pinned version before node check

Fixes

• fix(install): Correct nvm activation guard in install.sh (#57)
  • process.exit(+boolean) threw ERR_INVALID_ARG_TYPE in Node ≥22, causing the nvm block to silently never run. Fixed to Number(...) < 20 ? 1 : 0
  • nvm use 20 → nvm install 20 so missing versions are actually installed
  • install.ps1: nvm-windows doesn't read .nvmrc — fixed to nvm install 20; nvm use 20
  • install.ps1: fnm fallback changed to fnm install 20 to handle missing versions
  • Added validation for optional component.pythonVersion field in manifest validator

v1.2.1...v1.2.2

v1.2.1

Fixes

• fix(cli): Report the real release version in myelin --version — was showing a stale value after managed-runtime updates
• fix(install): Register the myelin CA bundle in the CA env vars (NODE_EXTRA_CA_CERTS / REQUESTS_CA_BUNDLE / SSL_CERT_FILE) — fixes UnknownIssuer errors on Linux when mitmproxy CA is not yet trusted (#51)

Maintenance

• Backlog: added CLAUDE-CMD-001 (Claude missing /myelin:compact + /myelin:constitution commands)
• Backlog: added INSTALL-BIN-002 (installer overwrites committed bin/myelin with machine-specific launcher)
• Backlog: added HLITE-B5 portability candidates from upstream headroom scan (cache collision, space-separated JSON, max_tokens translation, cache write premium)
• Backlog: added 5 dependency-update items (headroom-ai, serena, semble, agentcairn, tokenOptimizer)
• Backlog: marked HLITE-B4-001 done (headroom-lite PR #22, tag v0.31.0-1, manifest PR #52)

Full changelog

v1.2.0...v1.2.1

v1.2.0

Stable release with three live-machine reliability fixes (PR #50).

Fixes

• fix(install): mitmproxy CA no longer re-appended on every install/update. The presence check used a decoded X.509 subject (CN=mitmproxy) that never appears in a base64 PEM; now a single-source marker + exact-cert-body detection.
• fix(service): stops the recurring "install tears down the live proxy, only update fixes it" (Copilot ECONNREFUSED / os error 61) and the service-test clobber:
  • bootReplaceLaunchdService retries the bootstrap so a bootout/bootstrap EIO race never leaves a service DOWN.
  • isPortResponding retries so a busy-but-healthy proxy isn't needlessly restarted.
  • Allowlist guard (isManagedLaunchAgentPath) + injectable exec so tests can never hijack the real com.myelin.* launchd label.
  • Watchdog bash hardened: retries the probe, never revives a service launchd still reports running with a live PID, and retries the bootstrap.
• fix(mitm): the tool filter now skips filtering when the client uses deferred tool loading, fixing the provider 400 "At least one tool must have defer_loading=false".

Testing

Mac (1435 node + 309 py), Linux (1433 node), Windows (1389 node) — 0 failures; proven no live-proxy clobber. 3-model + final code review.
