Summary

• reconnect committed transcripts for modern fresh Codex sessions without selecting rollout files by recency
• pin codex-headless PR docs: note planned Agent Code rename #41 for process-wide fresh/resume ownership, real chunked input evidence, generation-bound physical tails, and bounded cleanup/privacy lifetimes
• prepare resume ownership before provider spawn in production and in the real-data live probe
• pin agent-transcript-parser PR Add interactive agent PTY debug terminal #21 and add its cross-package probe typecheck to Agent Code CI
• forward content-safe ownership decisions into recordings so held candidates are diagnosable without new raw prompt text

Fixes #632.

Recorded evidence

Seven sanitized fixtures were extracted from real rollouts before ownership changed. The corpus spans Codex 0.145.0, 0.147.0, failed 0.149.0 Agent Code sessions, concurrent same-CWD 0.149.1 siblings, and exact resume/subagent attachment. Successive independent RED gates were converted into recorded ordering, generation, observer, input, and lifetime regressions before each repair.

The final interactive blockers were at two real boundaries: xterm forwards ordinary typing as separate chunks, while the previous ownership ledger only recognized an atomic text-plus-Enter write; and accepted dev:ino evidence was discarded before a pathname-based physical tail opened. Those gaps left the committed transcript disconnected or allowed a later filesystem generation to be read under an earlier authorization.

Verification

• codex-headless: 92/92, contract, typecheck, build, packed artifact, accepted/latest upstream check at 0.149.1
• agent-transcript-parser: 94/94, contract, typecheck, build, packed artifact, plus monorepo-only live-probe typecheck
• Agent Code: typecheck and focused Codex readiness 9/9
• real Codex 0.149.1: typed fresh turn committed 12 entries; exact prepared resume committed 21; provider-backed Tab queue committed 29; exact prompt/response evidence and zero errors throughout
• backward-compatibility live sequence against repository Codex 0.144.4: 14/23/32 committed entries and zero errors
• exact intended heads: parent 793b1a4, codex-headless 6244eac, parser a3fee9d
• exact-head GitHub CI and an eighth independent review are required before merge
