aa1c65beb1 fix: TUI hardening — non-loopback LAN gate + assert cc_entrypoint (#115) (#122)
Two TUI-mode findings from the 2026-05-31 audit (ADR 0007):

1. The fail-loud LAN gate refused TUI boot only when CLAUDE_BIND === "0.0.0.0",
   but binding to a concrete LAN IP, a Tailscale 100.x address, or IPv6 :: is
   equally network-exposed and slipped through — letting any reachable peer drive
   the operator's full-filesystem claude session. New isLoopbackBind() treats only
   127.0.0.0/8 / ::1 / localhost / ::ffff:127.0.0.1 as safe; the gate now trips on
   any non-loopback bind (OCP_TUI_ALLOW_LAN=1 escape hatch retained).

2. verifyEntrypoint() was implemented and unit-tested but never wired: readTuiTranscript
   discarded the events and returned only text, so a silent degrade to the metered
   sdk-cli (Agent SDK) billing pool — which still returns text but costs money — went
   undetected. readTuiTranscript now returns { text, entrypoint }; runTuiTurn passes it
   through; callClaudeTui logs a "tui_entrypoint_mismatch" warning when configured cli
   mode yields a non-cli entrypoint (including null/unverified). callClaudeTui still
   returns Promise<string>, so singleflight/cache/completion downstream is unchanged.

ALIGNMENT.md: TUI is a proxy-side execution-mode bridge (ADR 0007); this adds a local
bind classifier (startup gate) + a non-fatal log assertion of an existing classification
— no Anthropic operation forwarded, so a cli.js citation is N/A under Rule 2. No
blacklisted tokens or port literals introduced; alignment.yml passes.

Independent fresh-context reviewer (opus): APPROVE WITH MINOR (Iron Rule 10) — verified
isLoopbackBind via truth table (no exposed address misclassified as loopback — the
dangerous direction), the full string→{text,entrypoint} contract ripple across all
callers (Promise<string> preserved), the mismatch logic (warns on sdk-cli AND null in
cli mode, silent for auto/off, non-fatal), and ALIGNMENT N/A via a fetch/header grep.
Minors are process-only (this commit body; a future lib/ extraction of the test-mirrored
helper). npm test → 181 passed, 0 failed.

Closes #115.

05a984df89 fix: OCP code-audit P1+P2 hardening (crash bugs + multi-tenant gates) (#106)
* fix(daemon): P1-1 guard proc.stdin against EPIPE crash

In spawnClaudeProcess, attach an error listener on proc.stdin BEFORE
the write/end calls so an EPIPE (child closed stdin mid-write) is
swallowed and logged rather than thrown as an unhandled exception.

The existing proc.on("error") listener is on the ChildProcess object,
NOT on the stdin Writable — it does not catch stdin write errors.

Hardening per OCP code audit; entry-surface contract unchanged for
single-user default path.

* fix(tui): P1-3 remove tool_use from isTerminalLine; only turn_duration is terminal

In interactive TUI mode, stop_reason=tool_use does NOT mean the turn is
complete. Claude handles the tool call internally and continues generating —
the transcript advances to another assistant entry. Treating tool_use as
terminal truncated tool-using turns mid-flight.

Only {type:"system", subtype:"turn_duration"} is the authoritative
completion marker (claude CLI v2.1.157+ interactive session transcript).

Updated two unit tests that previously asserted tool_use → true; they now
assert false (the correct behaviour). The real-fixture terminal detection
test is unaffected because the fixture uses turn_duration.

Hardening per OCP code audit; TUI path behaviour fix.

* fix(tui): P2-5 add -l (literal) flag to send-keys prompt paste

A prompt that equals a tmux key token (e.g. "C-c", "Escape") would be
interpreted as that key binding rather than typed as literal text.

The -l flag forces literal character-by-character input. The separate
Enter key event afterward deliberately omits -l so tmux sends a real
carriage-return keypress to submit the prompt line.

Authority: tmux send-keys(1) § -l flag. Hardening per OCP code audit.

* fix(audit): String-coerce parsed.error + stale tool_use comment (review fast-follow)

Folds the 2 minor findings from the independent review of the audit fixes:
- String(parsed.error) before .slice/message in callClaude + callClaudeStreaming
  (defensive: claude could emit a non-string result/error_message).
- correct the readTuiTranscript comment that still listed tool_use as terminal.
