A backward reset moves HEAD to an earlier commit while preserving the working tree — the working log needs to be reconstructed with correct coordinate-space attribution. + +This is handled by a separate quarantined function: + +```rust +fn reconstruct_working_log_after_backward_reset( + repo: &Repository, + old_tip: &str, + new_tip: &str, + final_state: Option>>, // working dir snapshot at exit time +) -> Result<()> +``` + +This function: +1. Reads the existing working log for `old_tip` (which already contains cumulative attribution data from the entire branch — NOT individual commit notes) +2. Filters to files that changed between `new_tip` and `old_tip` AND have AI attribution +3. Reads current working directory state (from `final_state` snapshot or live filesystem) +4. **Transforms attributions from old_head coordinate space to current file state** using diff-based line tracking (the working log's line numbers correspond to old_head's file content, but HEAD is now at new_tip — content may differ) +5. Writes the reconstructed working log keyed to `new_tip` +6. Deletes the old working log + +**Critical detail**: Step 4 is necessary because after `git reset --soft HEAD~3`, the working directory is unchanged but the working log was keyed to old_head's content state. If any of the undone commits changed file content (which they almost certainly did), the attribution line numbers in the old working log don't correspond to the file as it exists in the working tree. The transformation uses the same `update_attributions` diff-tracking mechanism already used elsewhere in the codebase. + +**What this is NOT**: The function does not "read authorship notes from undone commits and merge them." The working log at old_head already contains all attribution data accumulated during the session. It just needs coordinate-space transformation and re-keying. + +This is the ONE case that requires more than hunk-shifting. It is deliberately kept separate from the main shift path to avoid polluting the unified algorithm. + +--- + +## Daemon Detection Layer + +The daemon monitors trace2 events and fires `handle_rewrite_event` in two cases: + +### 1. Non-fast-forward ref move + +``` +On command completion: + For each ref change in NormalizedCommand.ref_changes: + 1. Filter: ref must match refs/heads/* + Exclude: HEAD, ORIG_HEAD, FETCH_HEAD, refs/remotes/*, refs/tags/*, refs/stash + 2. Collapse: if multiple changes for same branch, use (first_old, last_new) + 3. Check: is collapsed change non-fast-forward? + (git merge-base --is-ancestor → exit 1 means non-FF) + 4. Fire: handle_rewrite_event(repo, NonFastForward { old_tip, new_tip }) +``` + +This single rule catches: rebase, amend, reset --hard forward, interactive rebase, `update-ref` (including from tools like Graphite), squash merges, force-push receives. + +**Guards against false positives:** +- Skip if `old_oid` is null (`0000...`) — branch was just created, not rewritten +- Skip if reflog reason contains "fetch" — force-fetch into local refs/heads/* is not a local rewrite (the branch mirrors a remote, not local work) + +**Backward moves** (rewind/abort): handled by `derive_mappings_from_range_diff`'s pre-check which detects `merge-base == new_tip` and delegates to the reset reconstruction handler if needed. + +### 2. Cherry-pick completion + +``` +On command where cmd_name == "cherry-pick": + If ref_changes shows HEAD/branch moved forward (from reflog delta): + Derive (source, new) pairs (see Cherry-Pick section) + Fire: handle_rewrite_event(repo, CherryPickComplete { sources, new_commits }) +``` + +Note: The signal is ref movement via reflog delta, not exit code. A cherry-pick that exits 0 but makes no ref changes (e.g., `--no-commit`) correctly produces no event. + +### `update-ref` support + +**Single update-ref** (e.g., `git update-ref refs/heads/main `): Already supported — the daemon's HistoryAnalyzer parses the command args and emits a RefUpdated event, which triggers non-FF detection via the standard reflog delta path. + +**Batch `update-ref --stdin`** (used by Graphite, git-town, git-stack): Currently NOT supported — the daemon's parser returns `None` for `--stdin`/`--batch-updates` and falls back to reflog delta, but only tracks the current branch's reflog. Other branches moved in the batch are missed. + +**Deferred improvement**: Full batch support requires expanding `tracked_reflog_refs_for_command()` to monitor all `refs/heads/*` reflogs when the command is `update-ref`. This is an enhancement — single-ref support is sufficient for MVP. A single `update-ref --stdin` command would then produce N independent `NonFastForward` firings — one per `refs/heads/*` ref that moved non-FF. + +--- + +## Cherry-Pick Handling + +Cherry-pick is a fast-forward on the target branch, so non-FF detection won't fire. It gets its own detection path but calls the same `handle_rewrite_event` entrypoint. + +### Why it uses the unified function + +Cherry-picks can conflict. After conflict resolution, `diff-tree source_sha cherry_picked_sha` shows both base-difference line shifts AND conflict resolution edits in one set of hunks. Lines that were conflict-resolved land inside a hunk → correctly marked unattributed. This is identical to how the core shift function handles any other rewrite. + +### Clean cherry-pick (exit 0, no prior failure) + +``` +Sources: parse from argv (expand ranges via git rev-list if argv contains "..") +New commits: reflog entries since pre-command HEAD (labeled "cherry-pick:" or "commit (cherry-pick):") +Pairing: two-pass matching algorithm (see below) +``` + +No state needed. + +### Cherry-pick with conflicts (in-memory state) + +```rust +struct PendingCherryPick { + all_sources: Vec, // full source list (expanded from argv/ranges) + pre_command_head: String, // HEAD before the sequence started +} + +// Single HashMap, ephemeral process memory +pending_cherry_picks: HashMap +``` + +**State machine:** + +``` +On cherry-pick [shas...] (initial invocation, NOT --continue/--skip/--abort/--quit): + → Expand sources from argv (resolve ranges via git rev-list) + → Store PendingCherryPick { all_sources, pre_command_head } + (Regardless of exit code — stores on success too, consumed below) + +On cherry-pick with ref_changes showing HEAD moved (sequence complete): + → Retrieve stored entry + → Get all new commits from reflog since pre_command_head + → Run two-pass matching to pair sources with new commits + → Fire handle_rewrite_event(CherryPickComplete { sources, new_commits }) + → Clear map entry + +On cherry-pick --continue/--skip exit != 0: + → Still conflicting. NO ACTION on pending state. + (Critical: do NOT clear pending sources on failure — this is a bug in the current impl) + +On cherry-pick --skip with ref_changes showing HEAD moved: + → Sequence complete, same as above (fire event, clear entry) + +On cherry-pick --abort: + → Clear map entry. Abort undoes everything including previously-applied commits. + +On cherry-pick --quit: + → Clear map entry. Partial commits survive but their notes come from + normal commit flow (post-commit hook wrote them when they were created). +``` + +**Single-commit `git commit` bypass**: If a user resolves a single-commit cherry-pick conflict with `git commit` instead of `--continue`, the normal commit flow writes the authorship note correctly. The `PendingCherryPick` entry leaks in memory until daemon restart — acceptable since it's a small HashMap entry and the daemon cleans up on restart. + +**Lost on daemon restart:** Acceptable. A cherry-pick that conflicted before restart and completes after won't have its notes copied. + +### Two-pass matching algorithm + +Pairs source commits with new cherry-picked commits after a sequence completes. Handles: clean picks, conflict-resolved picks, `--skip`, edited subjects, duplicate subjects. + +``` +Input: + - sources: Vec // all original source SHAs, in order + - new_commits: Vec // all new commits since pre_command_head, in order + +Pass 1 (patch-id anchoring): + For each new commit, compute patch-id (git show | git patch-id --stable) + For each source, compute patch-id + Match pairs where patch-ids are identical (definitive for clean picks) + Mark both sides as matched + +Pass 2 (positional gap-fill): + Walk remaining unmatched sources and unmatched new commits in their original order + Since cherry-pick preserves sequence, pair positionally: + i-th unmatched new commit corresponds to i-th unmatched source + Sources left over after all new commits are paired = skipped (no new commit for them) + +Output: + Vec<(source_sha, new_sha)> for all successfully paired commits + (skipped sources are simply absent from the output) +``` + +This is O(n) after patch-id computation and handles all cases reliably. The order-preservation invariant of cherry-pick guarantees the positional fallback is correct. + +### `--no-commit` cherry-picks + +Ignored. No commit created, no reflog entry. The changes are staged — attribution is handled by the normal checkpoint → commit flow. + +--- + +## Stash Handling + +### On stash create + +Daemon sees stash SHA being created. Two actions: + +1. Write metadata file: + +``` +.git/ai/stashes/.json +``` + +```json +{ + "base_commit": "", + "timestamp": 1715000000, + "pathspecs": ["src/", "lib/"] // empty array = all files +} +``` + +The `pathspecs` field records which files were stashed (from argv parsing of `git stash push -- `). Needed for partial stash restoration — without it, popping a partial stash would incorrectly restore attributions for all files. + +2. **Clean up working log entries** for stashed files: + - Read the current working log at `base_commit` + - Remove INITIAL attribution entries for files matching pathspecs (or all files if no pathspecs) + - This prevents subsequent commits from using stale attributions for files that are no longer in the working tree + +### On stash pop/apply + +1. Read `.git/ai/stashes/.json` → get `base_commit` and `pathspecs` +2. If `base_commit != current HEAD`: call `migrate_working_log_if_needed(repo, &[(base_commit, current_HEAD)])` to shift attributions to current HEAD's coordinate space +3. Restore INITIAL attribution entries for stashed files (filtered by `pathspecs`) into the working log at current HEAD +4. On pop (not apply): delete the stash file + +**Conflict handling**: Even if `git stash pop` exits with non-zero code (merge conflict), attribution restoration still proceeds. The stashed files are in the working tree regardless of conflict state. + +### On stash drop + +Delete `.git/ai/stashes/.json` (no migration needed). + +### Stash SHA resolution + +The stash SHA is NOT in trace2 events directly. The daemon resolves it at **exit time** from the reflog delta for `refs/stash` — the delta captures what was at `refs/stash` before the command removed it (for pop/drop) or what was created (for push). This is the existing pattern: the daemon tracks reflog byte offsets at command start, reads the delta at exit. + +### Garbage collection + +On daemon startup, scan `.git/ai/stashes/` and remove entries whose SHA no longer exists in the stash reflog. + +--- + +## CI Module Migration + +The CI module (`src/ci/ci_context.rs`) is a **user-facing feature** that runs on GitHub/GitLab CI runners to handle merge operations (where no daemon is running). It currently calls `rewrite_authorship_after_rebase_v2` and `rewrite_authorship_after_squash_or_rebase` from the deleted `rebase_authorship.rs`. + +### Semantic note + +CI's use case is cross-branch: it maps `head_sha` (PR branch tip) → `merge_commit_sha` (post-merge on main). This is technically a different topology than same-branch non-FF moves that the daemon detects. However, `NonFastForward` still works correctly because `derive_mappings_from_range_diff` only cares about merge-base and tree diffs — not whether the commits are on the same branch. + +### Migration + +```rust +// Before (deleted): +rewrite_authorship_after_rebase_v2(repo, original_commits, new_commits, ...)?; + +// After: +handle_rewrite_event(repo, RewriteEvent::NonFastForward { + old_tip: original_tip.clone(), + new_tip: new_tip.clone(), +})?; +``` + +The CI module already has access to old_tip and new_tip. The new function derives mappings internally via range-diff, which is more robust than the CI module's current positional matching. + +**Additional deletion in ci_context.rs (~70 lines)**: The CI module currently pre-computes commit lists, detects rebase-vs-squash by comparing counts, and routes to different functions. All of this becomes redundant — `derive_mappings_from_range_diff` handles squash detection and commit mapping internally. The CI module shrinks from ~250 lines of rewrite logic to ~3 lines (a single `handle_rewrite_event` call). + +### CLI Dispatch + +Since `git_ai_handlers.rs` is deleted, `git-ai ci` commands need a new entry point. The minimal `main.rs` dispatch (see "main.rs routing" below) routes `git-ai ci *` directly to the CI module. The CI module itself (`src/ci/`) is unchanged except for swapping the rewrite function call. + +--- + +## Notes Push Syncing + +`push_hooks.rs` is deleted entirely.

This is the only point where sync happens. + +4. **Branch naming**: Rewrite operations create temporary branches. Use `registry.next_index()` in branch names to avoid collisions between operations within the same test. + +5. **Separate files for rebase/squash**: These operations use separate files (not `fuzz_target.txt`) to avoid merge conflicts that would require manual resolution. The main file is still verified after each operation. + +6. **The `write_to_disk` method uses a fresh rng for line length**: Each time the file is written, line lengths are randomly chosen (5-20 chars).

Since each step uses a unique char, the char present on a line unambiguously identifies which step wrote it last, and therefore what attribution it should have.
