[jnorthrup]

Solid Single PR Compromise

NARS head

<solid_PR --> max_value_upstream + jnorthrup + mailbox>. (1.0, 0.96)
<include --> {#13_stderr, #16_empty, #4_hermes, #17_effort, #14_gates, Jules, mailbox, attempts, NARS_strict}>. (0.97, 0.93)
<mailbox --> cheap_robust_JSONL_git_root + NARS_envelope + ≤200char>. (0.98, 0.95)
<exclude --> reifier_bloat | multi-section_NARS | badge>. (0.95, 0.91)

Mailbox investigation (cheap + robust)

• Canonical: <git-root>/.zenith/mailbox/ (symlink-safe)
• JSONL envelopes with required nars[] + body≤200
• Mission + per-session + sessions.json index
• Path-safe, tested through symlinks
• TODOs remain for fact harvest → prompts (next work item)
• Verdict: yes, cheap and robust for agent handoff

Included value

• Upstream use-driven: fix(acp): drain terminal-reviewer stderr so it can't stall before submit_terminal_review Intelligent-Internet/zenith#13, fix(validation): reject contract-less plans at submit_plan Intelligent-Internet/zenith#16 (verify)
• Open: feat(config): make codex reasoning effort configurable per role Intelligent-Internet/zenith#17 effort, Tighten gate checkpoints and skill validation Intelligent-Internet/zenith#14 gates
• jnorthrup: Jules ACP full + e2e + priority_respawn, coalesced attempts/fingerprints/tombstones, strict 10-line NARS + anti-slop guard, DRY prompts, local mode
