Summary

A child rollout, one whose session_meta names a parent_thread_id, is saved as
<agent>-sub<seq>-<role>.jsonl, the name #6970 gives. <seq> counts the kept child rollouts in
start-time order; <role> is the child's agent_role when it is a valid persona key and generic
otherwise (an unnamed V1 child records a null role). The root keeps <agent>-<basename>. Naming
only, as in #6970.

Inert until PR 6: main registers no roles and keeps the multi-agent tools off (#7829), so no run
produces a child rollout before the switch; every current run's artifacts are byte-equal.

Related Issue

Part of #6970. Supersedes the transcript part of #7809 (closed).

Changes

• internal/runtime/codex_transcript.go: sort the find listing by rollout basename; decode line
  1 of each validated rollout (codexSessionMeta, codexReadSessionMeta); name a child by its
  role (codexChildTranscriptName, codexGenericRole). Containment, rollout validation and
  redaction are called as before. On review: a rollout whose local name or basename is a
  transcript this extraction already saved is skipped before anything is truncated or
  downloaded over it, and a role the artifact redactor would mask is no role.
• internal/runtime/codex_transcript_test.go: a per-path fake openshell (the shared fake serves
  one body for every download); cases: named role, null role, invalid role, two children with the
  same role (seq 1 and 2), root unchanged, first line not a session_meta (kept under its
  basename, as today), not a rollout (discarded, as today), a reserved name (default) as
  role; a child is redacted.
• docs/contributing/runtime-implementation.md was consulted: its Codex transcript rows (rollout
  session JSONL, validated and redacted; transcripts/ holds rollouts) stay true, and the
  user-facing child name lands with the switch PR's Artifacts row.

Interpretations, for a maintainer to correct: <seq> counts kept child rollouts only, 1-based and
unpadded, in ascending basename order (pi uses the dispatch index and keeps a gap for a discarded
child; on Codex the runner sees only the files). A null, empty, malformed or reserved role
(default, which is a config key and never a persona name) or credential-shaped role is
generic. Only the first non-blank line decides identity.

Testing

• make lint passes (staged first)
• Tests added: TestCodexChildTranscriptName, TestCodexReadSessionMeta,
  TestCodexExtractTranscripts_NamesChildrenByRole, TestCodexExtractTranscripts_ChildNameRejected,
  TestCodexExtractTranscripts_DownloadLandingNameSaved; the existing transcript tests are unedited.
  Before the ExtractTranscripts change, the new test failed on the names: the four children were
  saved under <agent>-<basename>.
• go test -race ./internal/runtime/ and make go-test green; go vet clean.
• Base: origin/main at 0864bdc1; Codex pin CODEX_VERSION=0.159.3.
• Patch coverage (go tool cover -func): codexChildTranscriptName and codexReadSessionMeta
  100%, ExtractTranscripts 83.5%.

High-Level Assessment

Naming children during the existing extraction flow is appropriate: it uses the downloaded rollout’s metadata without changing which files are collected or how they are protected. A separate metadata pass or broader extraction redesign would add complexity without a clear benefit.

• Sorts rollout paths by basename and reads the first non-blank session metadata to identify children. Saved children receive sequential role-based names, with invalid or absent roles mapped to generic; roots retain their basename-based names.

1. Runtime guide review goes unrecorded ✗ Dismissed

Description

CodexRuntime.ExtractTranscripts now names child artifacts from rollout metadata, but the PR
description does not say that docs/contributing/runtime-implementation.md was consulted. Because
CodexRuntime implements the runtime backend and transcript handler, reviewers cannot verify that
the guide’s transcript-extraction guidance was checked for this change.

Code

internal/runtime/codex_transcript.go[R119-125]

+		if meta, metaErr := codexReadSessionMeta(stagePath); metaErr == nil && meta.ParentThreadID != "" {
+			role := codexGenericRole
+			if config.ValidSubagentKey(meta.AgentRole) {
+				role = meta.AgentRole
+			}
+			childName := codexChildTranscriptName(agentLabel, children+1, role)
+			cf, createErr := root.Create(childName)

Evidence

The checklist requires evidence that the runtime implementation guide was consulted when modifying a
runtime backend. The changed lines alter transcript naming; CodexRuntime implements both Runtime and
TranscriptHandler, and the guide identifies transcript extraction as the handler’s responsibility.
The supplied PR description contains no reference to consulting the guide.

2. A filename collision loses a transcript ✗ Dismissed

Description

ExtractTranscripts can give a child the same local name as a rollout whose basename is
sub<seq>-<role>.jsonl, and root.Create does not reject an existing file. If both rollouts are
present, processing the second removes or replaces the first artifact; even a subsequently discarded
rollout can erase one that was already saved.

Code

internal/runtime/codex_transcript.go[R124-125]

+			childName := codexChildTranscriptName(agentLabel, children+1, role)
+			cf, createErr := root.Create(childName)

Evidence

Root names incorporate the remote basename, while the new child name is generated from the sequence
and role. Session-path validation does not exclude a basename such as sub1-correctness.jsonl, and
rollout validation checks envelope content rather than filename; root.Create and the subsequent
removal do not preserve a file already at that name.

3. A reserved key appears as a child role ✓ Resolved

Description

ExtractTranscripts uses config.ValidSubagentKey alone to accept agent_role, which admits
default even though it is reserved for blanket configuration rather than a persona. A child
rollout carrying that value is saved with a -default.jsonl suffix instead of the generic fallback
used for unusable roles.

Code

internal/runtime/codex_transcript.go[R121-123]

+			if config.ValidSubagentKey(meta.AgentRole) {
+				role = meta.AgentRole
+			}

Evidence

ValidSubagentKey explicitly accepts default, while the configuration code explicitly states that
it is never a legal persona name. The new naming branch applies no further check before putting the
role into the filename.

internal/runtime/codex_transcript.go[119-124]
internal/config/config.go[299-321]

Agent prompt

The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
The child-role check accepts `default`, a configuration key that cannot name a persona.
## Fix Focus Areas
- internal/runtime/codex_transcript.go[119-124]
- internal/runtime/codex_transcript_test.go[711-768]
## Recommended Fix
Treat `default` as an unusable child role and use `generic` for it. Add a transcript naming test for `agent_role: "default"`.

Looks good to me

Earlier findings

• f_0a52d0b8e397b7fd — resolved_by_change: the skip guard now also checks saved[filepath.Base(remotePath)], covered by TestCodexExtractTranscripts_DownloadLandingNameSaved.
• f_41015d99990e33cd — resolved_by_change: require.True(config.ValidSubagentKey("sk-a...")) added to the role-naming test.
• f_b03b4dfcc7d36f44 — reclassified (info): no role-specific redaction bypass found.

Review

Findings

Medium

• [logic-error] internal/runtime/codex_transcript.go:89 — The new saved[localName] guard does not protect the intermediate path sandbox.DownloadFile uses. That helper (internal/sandbox/sandbox.go) removes and downloads to outputDir/<remote basename> and only then renames to the stage path. With agentLabel="triage", a child saved as triage-sub1-correctness.jsonl can be deleted, and overwritten with the raw unredacted download, by a later-sorted agent-writable remote file named triage-sub1-correctness.jsonl. That file passes the saved[localName] check because localName is triage-triage-sub1-correctness.jsonl. If the later file then fails rollout validation, neither transcript survives. The new collision fixture (sub1-correctness.jsonl, unprefixed) never reaches this path.
  Remediation: Download each candidate into an isolated temporary staging directory so DownloadFile's basename-derived intermediate path cannot overlap saved artifacts. Add a regression test with agentLabel="triage" and a later remote basename triage-sub1-correctness.jsonl that fails rollout validation, and assert the original child's contents survive.

Low

• [missing-test] internal/runtime/codex_transcript_test.go:742 — The credential-shaped role fixture "sk-a..." fails config.ValidSubagentKey (periods), so evaluation short-circuits before redactSummary(role) and the test still passes if the redactor check is removed.
  Remediation: Use a synthetic role that passes persona-key validation and matches the OpenAI pattern, e.g. "sk-" followed by 20 or more lowercase letters. Assert it becomes generic and appears in no output filename.

Earlier findings

• f_b03b4dfcc7d36f44 — reclassified (low → info): the redactSummary(role) != role check now masks full credential-shaped roles. A below-threshold fragment can still pass, but the rollout body is redacted with the same pattern thresholds, so the filename adds no exposure channel beyond the existing redaction limits.

Review

Findings

Low

• [secret-exposure] internal/runtime/codex_transcript.go:122 — The child rollout's agent_role is read from an agent-writable file and copied into the artifact filename before codexRedactFile runs. config.ValidSubagentKey and the new reserved-name check (default, explore) restrict shape and length but not content. A role such as glpat- followed by 20 or more lowercase alphanumerics passes both checks and matches the shared gitlab_pat pattern at internal/security/redactor.go:221. Redaction rewrites the file contents only, so that value stays in the saved filename and in the Saved transcript log line. Real tokens with uppercase letters or underscores fail the shape check, which limits exposure. Inputs checked: the role is shape-validated, <seq> is runner-generated, agentLabel comes from the caller, and the combined name gets the os.Root containment check. The role-derived filename is not redacted.
  Remediation: Before using agent_role as the filename role, run it through the shared secret redactor and fall back to generic if redaction changes it. Add regression tests for a valid-shaped credential role and a registered lowercase runtime secret, checking both artifact names and extraction logs.

Earlier findings

• f_d8ec950aa25d925f — resolved_by_change: the latest commit rejects reserved role names (default, explore) via config.ReservedSubagentKeys() and adds an extraction test case where role default is saved as review-sub5-generic.jsonl.

Review

Findings

Low

• [logic-error] internal/runtime/codex_transcript.go:125 — Child names (<agent>-sub<N>-<role>.jsonl) share the output namespace with root names (<agent>-<basename>). root.Create truncates and os.Remove(localPath) deletes an existing file of that name, so a rollout whose basename happens to look like a child name (e.g. sub1-correctness.jsonl) and a child can overwrite each other, order-dependent. Real codex rollouts start with rollout-, so this needs an agent-crafted basename in the agent-writable sessions dir; same-basename overwrite across date directories already existed. The new tests use only distinct rollout-* basenames.
  Remediation (optional hardening): track destinations used in this extraction and skip/rename on collision instead of truncating; add a test for both processing orders.

• [secret-exposure] internal/runtime/codex_transcript.go:122 — A role that passes config.ValidSubagentKey (lowercase alphanumerics and hyphens, ≤64 chars) goes into the filename and the "Saved transcript" stderr line unredacted, so a value like sk- plus 20+ lowercase letters would match the OpenAI-key pattern and appear unmasked. This adds no new channel: the root path's agent-controlled basename is already used unredacted and is wider.
  Remediation (optional hardening): run the role through the shared redactor and fall back to generic if it changes.
