Pull request overview
This PR addresses attribution “inflation” caused by counting non-agent file changes from intermediate commits by switching non-agent file detection to prefer a per-commit diff base (first parent → HEAD) when available.
Changes:
- Plumbs
parentCommitHashfrom the post-commit hook into condensation/attribution calculation. - Updates attribution logic to prefer
parentCommitHash→headCommitHashfor enumerating non-agent changed files (falling back toattributionBaseCommit→headCommitHash). - Updates unit tests to match the new
CalculateAttributionWithAccumulatedsignature.

Autofix Details
Bugbot Autofix prepared fixes for both issues found in the latest run.
- ✅ Fixed: Non-agent file line counting inconsistent with file scoping
- Threaded parentTree through condenseOpts/attributionOpts/CalculateAttributionWithAccumulated and used it instead of baseTree for non-agent file line counting, so diffs are now parent→head (consistent with file scoping) instead of session-base→head.
- ✅ Fixed: Duplicated parent commit hash computation in handlers
- Precomputed parentCommitHash alongside parentTree in PostCommit, stored it on the postCommitActionHandler struct, and replaced the duplicated 6-line blocks in HandleCondense and HandleCondenseIfFilesTouched with the precomputed field.

Pre-session dirty files (CLI config files from `entire enable`, leftover changes from previous sessions) were incorrectly counted as human contributions, deflating agent percentage. Root cause: PA1 (first prompt attribution) captures worktree state at session start. This data was used to correct agent line counts (correct) but also added to human contributions (wrong). Fix: - Split prompt attributions into baseline (PA1) and session (PA2+) - PA1 data still subtracted from agent work (correct agent calc) - PA1 contributions excluded from relevantAccumulatedUser - PA1 removals excluded from totalUserRemoved - Include PendingPromptAttribution during condensation for agents that skip SaveStep (e.g., Codex mid-turn commits) - Add .entire/ filter to attribution calc (matches existing PA filter) - Fix wrapcheck lint errors in updateCombinedAttributionForCheckpoint Verified end-to-end: 100% agent with config files committed alongside.

Three fixes for multi-session attribution: 1. Cross-session file exclusion: Thread allAgentFiles (union of all sessions' FilesTouched) through the attribution pipeline. Files created by other agent sessions are no longer counted as human work. 2. Exclude .entire/ from commit session fallback: When the commit session has no FilesTouched and falls back to all committed files, filter out .entire/ metadata created by `entire enable`. 3. PA1 baseline uses base tree for new sessions: New sessions (StepCount == 0) always diff against the base commit tree, not the shared shadow branch which may contain other sessions' state.

Summary
Fixes attribution inflation that caused agent percentages to be incorrectly deflated, and adds holistic combined attribution for multi-session checkpoints. Supersedes #813.
Problems Fixed
1. Intermediate commit inflation
When calculating non-agent file contributions, the code used
attributionBaseCommit → headCommitHash(session start → current commit). In multi-commit sessions, this counted ALL user edits since session start instead of just this commit's changes.Fix: Use
parentCommitHash → headCommitHash(first parent → current commit) so only this commit's non-agent file changes are counted.2. Pre-session worktree dirt
PA1 (first PromptAttribution) captures the worktree state at session start, which includes files already dirty before the session (CLI config from
entire enable, leftover changes). These were incorrectly added to human contribution counts.Fix: Split prompt attributions into baseline (PA1,
CheckpointNumber <= 1) and session (PA2+). PA1 is used for agent line correction but excluded from human counts.3. Multi-session cross-contamination
In multi-session commits (e.g., 3
claude -pcalls then commit), each session's attribution counted files from OTHER agent sessions as human work. Session A creatingblue.mdwould see Session B'sred.mdas human-added.Fix: Thread
allAgentFiles(union of all sessions'FilesTouched) through the attribution pipeline. Files touched by any agent session are excluded from human counts in all sessions.4. Commit session claiming
.entire/config filesWhen a session with no
FilesTouched(e.g., a commit-only session) falls back to using all committed files,.entire/config files fromentire enablewere included as agent work.Fix: Filter
.entire/paths from the fallback incommittedFilesExcludingMetadata().5. PA1 using shared shadow branch for new sessions
New sessions incorrectly used the shadow branch (which may contain other sessions' checkpoint data) as the PA1 reference. This caused pre-session worktree dirt to be missed because it already existed in the shared shadow tree.
Fix: New sessions (
StepCount == 0) always diff against the base commit tree for PA1, not the shadow branch.6. Combined attribution (replaces #813)
Added holistic
combined_attributionfield onCheckpointSummaryfor multi-session checkpoints. Instead of naively summing per-session values (which double-counts), this diffsparent → HEADonce and classifies files as agent vs human based on the union of sessions with real checkpoints (CheckpointsCount > 0). Filters.entire/and.claude/config paths.Test Results
