[1.88.0] - 2026-06-03

Added

• Three-platform daemon autostart templates (#163). The repo now ships install helpers so the evolver daemon auto-starts on login with restart-on-failure on every supported OS, matching the existing Linux scripts/evolver.service: a macOS launchd agent (scripts/com.evomap.evolver.plist, KeepAlive.SuccessfulExit=false + ThrottleInterval=5 mirroring Restart=on-failure/RestartSec=5) and a Windows Task Scheduler installer (scripts/install-evolver-windows.ps1, -Install/-Uninstall). The Windows shape launches via a generated %LOCALAPPDATA%\EvoMap\evolver-task-launcher.vbs with the node/index paths baked into VBScript literals and a single quoted task argument — wscript is a Windows-subsystem host so no console window appears on logon, and WScript.Quit rc propagates the exit code so restart-on-failure still observes failures. All three platforms verified live through a real reboot.

• Explicit signal injection channel (#172). A new fifth injection point in the signal-extraction stage reads user-declared signals from <gep-assets-dir>/pending_signals.json (default .evolver/gep) and merges them into a cycle's signal set, bypassing the closed 20-entry OPPORTUNITY_SIGNALS vocabulary. This lets a human-verified, deterministic capability whose intent no extractor can name still surface as a first-class signal (previously it collapsed to a generic capability_gap and the dedicated gene could never win selection). File-locked read-once semantics (consumePendingSignals() empties the file after consuming), entries trimmed and length-capped (≤200), non-fatal on error.

Fixed

• Heartbeat / daemon-survival resilience overhaul (#163). A nine-round hardening pass on the keep-alive path, addressing failure modes that left the daemon silently dead after sleep/wake, idle windows, or concurrent startup:
• Singleton-lock takeover is now atomic — linkSync + EEXIST guard (with a renameSync fallback for link-less filesystems), replacing a non-atomic unlinkSync-before-write that could let two daemons both "own" the lock and rotate node_secret against each other into mutual 401 backoff. Lock carries a lease: true marker + mtime refreshed every LOCK_REFRESH_MS (60s Win / 120s POSIX); takeover honors both dead-PID (kill -0 ESRCH) and lease-expiry (mtime older than STALE_LOCK_TTL_MS, 3min Win / 5min POSIX).
• sd_notify watchdog actually fires under systemd — shells out to systemd-notify(1) (with NotifyAccess=all) instead of the broken dgram unix_dgram socket, which threw synchronously on node ≥22 and swallowed READY=1/WATCHDOG=1.
• Sleep/wake recovery — a wall-clock drift detector (samples Date.now() every 30s, treats a >90s jump as a wake; cpuUsage-vs-wall-clock delta distinguishes CPU throttling from true sleep), a stuck-tick watchdog, and a wake ritual that drains dead undici connections + restarts SSE.
• Event-loop anchor + process survival — a ref'd 10-min keepalive tick keeps the loop alive and leaves a disk heartbeat for checkHealth; EPIPE is swallowed without killing the process while non-EPIPE stream errors are still surfaced; unhandledRejection consults live heartbeat stats rather than killing a process mid-recovery.
• Hostile-hub clamps — 429 backoff capped at 30min so a malicious/buggy retry_after_ms: 86_400_000 can't silence the heartbeat for a day; unknown_node anti-cache-poisoning backoff with an absolute deadline.

• Removed a dead wake hook in evolver-signal-detect.js whose relative require was MODULE_NOT_FOUND in the deployed .claude/hooks/ layout (no in-proc consumer exists, so it was a no-op that cost a 3000-line require on every IDE edit).

• Standalone-binary obfuscation retries (#171). Default OBF_MAX_ATTEMPTS raised 4 → 12 in scripts/build_binaries.js. The obfuscation step occasionally mangles new.target into an illegal #target token, non-deterministically across node processes; the seed-perturbation retry is the right mechanism but 4 attempts wasn't enough (the v1.87.4 deploy hit 4/4 and aborted before npm publish + binary upload). No behavior change on first-attempt success; env override unchanged.
