@ryoppippi This is a clean, well-executed structural refactoring. Here's the full review:

Review Summary ✅

No functional changes — pure module reorganization.

What was verified

Minor observation (non-blocking)

The relocated snapshot file has a stale source: metadata field:

source: crates/ccusage/src/adapter/codex.rs

It should now reflect crates/ccusage/src/adapter/codex/mod.rs. This is purely cosmetic — insta records this at snapshot-generation time and it doesn't affect test correctness. It will self-correct the next time the snapshot is regenerated via cargo insta review.

The PR achieves its goal perfectly. No issues.

@coderabbitai review

Pushed commit `a93310d` to update the moved Codex snapshot metadata after your non-blocking observation. Please review the latest change.

#!/bin/bash
# Check the snapshot file metadata after the fix
find rust/crates/ccusage/src/adapter/codex -name "*.snap" | sort

# Show the header of the snapshot file
find rust/crates/ccusage/src/adapter/codex -name "*.snap" -exec head -10 {} \;

@ryoppippi The snapshot metadata is now correct — source: crates/ccusage/src/adapter/codex/mod.rs ✅. The fix precisely addresses the observation. All good!

commit: 65fc9e9

ccusage performance comparison

PR SHA: 65fc9e99f0ff
Base SHA: bd6c3dda680e

This compares the Rust PR release binary against the configured base package on the same CI runner.

Package runner startup

Execution setup measures any pre-benchmark package materialization used by the execution benchmark. Bunx temp cache measures one bunx -p <url> ccusage --version run with an empty Bun install cache. Warm reuses that cache and reports the median of repeated runs.

Cached bunx execution performance

Runs the same large fixture through bunx -p <pkg.pr.new URL> ccusage after the Bun install cache has already been populated by the startup measurement. This separates cached package-runner execution from first-fetch package materialization.

Fixtures: Claude /home/runner/work/_temp/ccusage-large-fixture (1.01 GiB, 2,597 files), Codex /home/runner/work/_temp/ccusage-large-codex-fixture (1.01 GiB, 2,597 files)
Base package: bd6c3dda680e; PR package: 65fc9e99f0ff. Both run through bunx -p <pkg.pr.new URL> ccusage using the warmed Bun install cache from package runner startup, measured by hyperfine with 0 warmups and 1 runs.

Package runtime diagnostics

Compares the PR package wrapper, the installed native optional dependency binary, and the workspace release binary on the same large fixture. This identifies whether slow package results come from JavaScript wrapper overhead, the published native binary build, or the Rust core itself.

All rows run --offline --json, measured by hyperfine with 0 warmups and 1 runs. This isolates wrapper overhead from the installed native optional dependency and the workspace release binary built on the runner.

Committed fixture performance

Committed small fixtures for stable PR-to-PR feedback and explicit Claude/Codex command coverage.

Fixtures: Claude apps/ccusage/test/fixtures/claude (0.00 MiB, 2 files), Codex apps/ccusage/test/fixtures/codex (0.00 MiB, 1 files)
Base runs the published ccusage package from pkg.pr.new, installed before measurement; PR runs rust/target/release/ccusage directly. Both run --offline --json, measured by hyperfine with 2 warmups and 7 runs.

Large real-world-shaped fixture performance

Generated fixtures shaped from aggregate local log statistics: thousands of JSONL files, many small sessions, and a long tail of larger sessions. No real prompts, paths, or outputs are stored in the fixtures.

Artifact size

Lower medians and smaller artifacts are better. CI runner noise still applies; use same-run ratios as directional PR feedback, not release guarantees.
