* docs(spec): design for #47 SSE heartbeat on streaming path
Draft spec for an opt-in idle-watchdog SSE heartbeat covering both
pre-first-byte and mid-stream silent windows. Default disabled,
controlled by CLAUDE_HEARTBEAT_INTERVAL. Targets ~40 LOC.
Decisions captured: D1 whole-stream reset-on-byte; D2 SSE comment
frame; D3 default disabled; D4 relocate ensureHeaders() to post-spawn;
D5 X-Accel-Buffering: no on both SSE header sites; D6 single log line
per affected request.
Scope-locked: does not touch CLAUDE_TIMEOUT semantics, the separate
server.mjs:480-489 dangling-client bug, issues #41/#42, or the
non-streaming path.
Includes privacy preflight and cloud-testing plan per maintainer
feedback.

* docs(plan): implementation plan for #47 SSE heartbeat
6 phases: pre-work (file 480-bug), implementation (5 tasks on
feat/47-sse-heartbeat), opus fresh-context review, cloud verification
on Mac rig, privacy preflight, PR+release.
Each implementation task carries concrete code, syntax check, and a
scoped commit message. LOC budget enforced in Task 1.6 gate (~45
server.mjs lines max). Reviewer checklist scopes scope-lock, ALIGNMENT,
privacy, and heartbeat-cannot-abort discipline.

* feat(server): add startHeartbeat helper + HEARTBEAT_INTERVAL env var
Per design doc (refs #47). Helper is a per-request idle watchdog that
emits `: keepalive\n\n` SSE comment frames; returns a {reset, stop} handle.
No wiring yet — helper is unused, safe to commit in isolation.

layer, not a cli.js operation. See AGENTS.md and ALIGNMENT.md Rule 2.

* refactor(server): eagerly send SSE headers post-spawn (D4, refs #47)
Moves the ensureHeaders() call from "on first stdout byte" to
"immediately after successful spawn." This is a prerequisite for the
heartbeat covering the pre-first-byte silent window (the 'processing
large contexts' failure mode in #47).
Behavioral consequence: the narrow "spawn succeeded but subprocess died
before any byte" branch at server.mjs:610-611 becomes effectively dead
in the common case. The post-headers SSE-stop path (612-619) handles
it instead. The branch remains defensively for the client-closed-before-
ensureHeaders race.
Isolated commit per design doc §D4 so reviewer can focus on this one
behavior change.

* feat(server): wire heartbeat into streaming path (refs #47)
- sendSSE() accepts optional hb handle and calls hb.reset() before write
- callClaudeStreaming starts heartbeat after ensureHeaders() and passes
hb to the three streaming sendSSE call sites
- All three exit paths (proc close, proc error, res close) call
hb.stop() to guarantee timer cleanup; no-op handle when disabled
means zero runtime cost when CLAUDE_HEARTBEAT_INTERVAL=0
Heartbeat never aborts — only writes comment frames and re-arms. Aligns
with v3.3 timeout discipline (single CLAUDE_TIMEOUT, no secondary
client-killing timers).

* feat(server): add X-Accel-Buffering: no to SSE response headers (refs #47)
nginx (and many LBs / Cloudflare) default to proxy_buffering=on, which
would buffer heartbeat comment frames indefinitely and defeat the
feature silently. This header hints no-buffering; other stacks ignore
it. Applied at both SSE header sites (real streaming + cache-hit).

* chore(release): v3.12.0 — streaming heartbeat (refs #47)
Bundles the release-kit companion files per Iron Rule 5.2 / 11 example:
version bump across package.json + ocp-plugin + openclaw.plugin.json,
CHANGELOG v3.12.0 section, README env var row + "Streaming heartbeat"
explainer.
Tag push to v3.12.0 triggers .github/workflows/release.yml to create
the GitHub Release automatically.

* fix(server): ensureHeaders returns true when already sent (refs #47)
Phase 3 smoke test revealed every content chunk was being dropped
after the D4 eager ensureHeaders() call: the stdout.on('data') guard
`if (!ensureHeaders()) return;` early-returned on every chunk because
ensureHeaders returned false for the already-sent case (conflated with
the dead-connection case).
Split the two conditions explicitly: return false only when res is
ended/destroyed; return true when headers are (already or now) sent.
This also fixes a latent multi-chunk bug on main that was masked
because claude CLI typically outputs in one stdout chunk.
Verified: node -c server.mjs; subsequent re-run of Phase 3 smoke test
now sees streaming content chunks + heartbeat frames.
