Verdict

Non-blocking, but this dead-code cleanup leaves one stale reference behind.

Themes

• pkg/workflow/README.md still advertises GetLogParserBootstrap even though this PR deletes the function. That leaves the exported API inventory out of sync with the code and sends future readers/tooling toward a symbol that no longer exists.

Removing GetLogParserBootstrap without updating pkg/workflow/README.md leaves the exported API inventory pointing at a symbol that no longer exists, which is exactly the kind of stale reference dead-code cleanup should remove in the same PR.

pkg/workflow/README.md still lists GetLogParserBootstrap at line 1412. Please delete that row here so repo docs and any tooling built from that inventory do not im…

Skills-Based Review 🧠

Clean, mechanical dead-code removal — no skill-specific issues found.

📋 Analysis

Change type

Pure deletion (0 additions, 63 deletions across 5 files). No new abstractions, no behavior change, and no bug being fixed, so /tdd, /diagnosing-bugs, /codebase-design, and /improve-codebase-architecture do not surface meaningful findings here.

Verification performed

• Confirmed CodexEngine.extractCodexTokenUsage and GetLogParserBootstrap have zero remaining references anywhere in the Go codebase.
• Ran go build ./... — succeeds.
• Ran go vet ./... — clean.
• Corresponding unit tests (TestCodexExtractTokenUsageTotalTokensPattern, TestGetLogParserBootstrap) were removed alongside the dead functions, keeping test/code parity.
• codex_logs.go's remaining extractCodexLegacyTokenCount (the real logic extractCodexTokenUsage used to wrap) is still present and exercised by TestCodexParseLogMetricsLegacyTokenSnapshots.

Positive highlights

• ✅ Comment references updated in codex_engine.go (stale // extractCodexTokenUsage is implemented in codex_logs.go pointer removed) rather than left dangling.
• ✅ Tests removed in lockstep with the functions they covered — no orphaned test failures introduced.

No blocking issues. Approving.
