Two-layer keepalive so headless services (gateway, ollama) aren't reaped by the Codespaces idle timeout: - keepalive.sh: (A) periodic terminal heartbeat on the session tty to mimic client activity (GitHub platform idle signal); (B) pinger to the VS Code server internal /delay-shutdown endpoint to reset the 5-min server-side shutdown timer. Zero-auth endpoint, verified HTTP 200. - start-hermes.sh: start keepalive idempotently (pgrep-guarded) on every codespace start/rebuild, using existing SCRIPT_DIR var. - wiki/keepalive-proposal.md: design, layers, success criteria, risks. - wiki/codespace-lifecycle.md: reference on Codespaces idle detection. (Folds in the removed orphan skill's content.) - wiki/INDEX.md + mnemon/seed.json updated (keepalive, importance=5). Shell syntax, seed.json validation, and keepalive --test pass locally.
Add a new section to the github-codespace skill documenting the background + notify_on_complete pattern for watching long CI builds without blocking the agent turn or burning a sleep-polling loop. Cross-reference this in the codespace-playbook wiki (Step 3: Monitor) as a third option alongside polling and streaming approaches, so both the skill (procedural) and wiki (reference) stay in sync. Skill change: .devcontainer/skills/github-codespace/SKILL.md - "Non-blocking watch from an agent turn" subsection under CI Monitoring Wiki change: .devcontainer/wiki/codespace-playbook.md - "Agent session approach" bullet in Step 3: Monitor (Poll or Stream) - links to the skill for full rationale and code No functional code changes; documentation/skill only.
Replace the hardcoded hermes PID (17522) with runtime pgrep discovery that resolves the interactive hermes process attached to a tty, skipping the headless gateway/dashboard/supervised processes. Keeps keepalive portable across rebuilds and CI (where that PID won't exist).
- Resolve SCRIPT_DIR/SELF from the script's own location so --test passes when invoked from the repo root or CI, not just from .devcontainer/. - Fix handed-off \n Note echo that printed a literal backslash-n.

Summary
Implements a two-layer Codespaces keepalive so headless services (gateway, ollama) aren't reaped by the idle timeout, and folds in the CI-watch skill/playbook improvement.
Changes
/delay-shutdownendpoint (zero-auth, verified HTTP 200). The heartbeat targets the interactive hermes process's tty, discovered at runtime via pgrep (no hardcoded PID) so it stays portable across rebuilds/CI.gh run watchas a background terminal withnotify_on_completeinstead of sleep-polling.Notes
codespace-lifecycleskill (had broken references/); content folded into wiki article.Verification
keepalive.sh --testall pass locally.
