The resulting checkpoint is submitted to the daemon for processing. Two problems arise: + +1. **Blocking latency:** Live checkpoints require the daemon to process synchronously, adding latency to every bash tool call. +2. **Race condition with queued checkpoints:** If earlier checkpoints are still queued in the daemon, files may have been modified by prior operations whose checkpoints haven't been processed yet. The bash tool's post-snapshot would incorrectly attribute those earlier changes to the bash command. + +## Solution + +Convert the bash tool's checkpoint flow to use the **captured (async) checkpoint** pattern that already exists for scoped file-edit tools. The key additions: + +1. A new daemon API to query per-file mtime watermarks (last-snapshotted mtime per file). +2. Pre-hook content capture of files that changed since the daemon's last checkpoint. +3. Post-hook content capture of files the bash command modified. +4. Both submitted as fire-and-forget captured checkpoints. + +## Approach + +**Approach A (selected):** Daemon watermark query + two captured checkpoints per bash call. The daemon exposes watermarks, the CLI captures content, and submits async. Chosen over: +- Approach B (post-hook only upgrade): doesn't solve the inter-checkpoint race. +- Approach C (daemon-side orchestration): too much daemon complexity, harder to test. + +## Design + +### 1. Daemon Watermark Query API + +**New control request** in `src/daemon/control_api.rs`: + +```rust +// method: "snapshot.watermarks" +ControlRequest::SnapshotWatermarks { + repo_working_dir: String, +} +``` + +**Response:** +```rust +ControlResponse { + ok: true, + data: Some(json!({ + "watermarks": { "src/main.rs": 1711234567890000000_u128, ... } + })), +} +``` + +Returns a `HashMap` mapping relative file paths to `last_checkpoint_mtime_ns`. + +**Daemon-side state** (in `src/daemon.rs` or `src/daemon/domain.rs`): + +Add `file_snapshot_watermarks: HashMap` to per-family state. Updated during `apply_checkpoint_side_effect()` — when a checkpoint processes file X, set `watermarks[X] = X.mtime_at_checkpoint_time`. + +**Staleness is safe:** If unprocessed checkpoints are queued, the watermarks will be behind reality. This causes the pre-hook to capture MORE files than necessary (conservative). The daemon's ordered queue ensures correct final state regardless. + +**Handler:** Route `SnapshotWatermarks` through the existing `handle_control_request()` dispatcher. The handler resolves the family key and reads watermarks via a new `FamilyMsg::GetWatermarks` message to the family actor (following the same pattern as `FamilyMsg::Status`). This ensures thread-safe access since all `FamilyState` reads/writes go through the actor's message channel. + +**Serialization:** The new `file_snapshot_watermarks` field on `FamilyState` must use `#[serde(default)]` to maintain backward compatibility with persisted state. + +**Timeout:** The watermark query uses a tight 500ms timeout (not the 300s checkpoint timeout). On failure, the pre-hook proceeds without content capture (graceful degradation). + +### 2. Bash Tool Content Capture + +Extend `handle_bash_tool` in `src/commands/checkpoint_agent/bash_tool.rs`. + +**New types:** + +```rust +pub struct BashToolResult { + pub action: BashCheckpointAction, + pub captured_checkpoint: Option, +} + +pub struct CapturedCheckpointInfo { + pub capture_id: String, + pub repo_working_dir: String, +} +``` + +**Mtime conversion:** `StatEntry.mtime` is `Option`. Watermarks are `u128` nanoseconds since epoch. A helper function converts between them: + +```rust +fn system_time_to_nanos(t: SystemTime) -> u128 { + t.duration_since(SystemTime::UNIX_EPOCH) + .unwrap_or_default() + .as_nanos() +} +``` + +Comparison uses a grace window of 2 seconds (matching `_MTIME_GRACE_WINDOW_SECS`) to handle low-resolution filesystems (HFS+ has 1s granularity): `mtime_ns > watermark + GRACE_WINDOW_NS` means the file has changed. + +**Pre-hook flow (daemon mode):** + +1. Clean up stale snapshots (existing). +2. Take stat-snapshot (existing). +3. Save stat-snapshot to disk (existing). +4. **Query daemon for watermarks** via `send_control_request(SnapshotWatermarks { repo_working_dir })`. On failure (timeout, no daemon), skip steps 5-7. +5. **Find files where `system_time_to_nanos(stat_entry.mtime) > watermark[file] + GRACE_WINDOW_NS`** — these changed since the daemon's last checkpoint. +6. **Filter to git-dirty files only** — use the tracked_files set from the stat-snapshot, plus any untracked files that pass gitignore. +7. **If any stale files found:** read their content into a `HashMap`, then construct a synthetic `AgentRunResult` with `will_edit_filepaths: Some(stale_file_paths)` and `dirty_files: Some(content_map)`. Call `prepare_captured_checkpoint()` with `CheckpointKind::Human`. The synthetic result provides the file list that `explicit_capture_target_paths()` needs, and `dirty_files` provides the inline content so the capture pipeline reads from memory rather than re-reading from disk. +8.

Return `BashToolResult { action: Checkpoint(paths), captured_checkpoint: Some(info) }`. + +**`handle_bash_tool` prepares but does NOT submit** the captured checkpoint.

Binary files are skipped. Errors are logged and the file is omitted from the capture (the daemon will handle the gap via its existing fallback logic). + +### 3. AgentRunResult Extension + +In `src/authorship/working_log.rs` (or wherever `AgentRunResult` is defined): + +```rust +pub struct AgentRunResult { + // ... existing fields ... + pub captured_checkpoint_id: Option, +} +``` + +When this field is `Some(capture_id)`, the handler layer submits a `CapturedCheckpointRunRequest` instead of a live checkpoint. + +### 4. Preset/Handler Integration + +**Agent presets** (`agent_presets.rs`, `amp_preset.rs`, `opencode_preset.rs`): + +Each preset's bash tool handling changes from: + +```rust +// Before +let action = handle_bash_tool(event, repo_root, session_id, tool_use_id)?; +match action { + BashCheckpointAction::Checkpoint(paths) => { /* set edited_filepaths */ } + ... +} +``` + +To: + +```rust +// After +let result = handle_bash_tool(event, repo_root, session_id, tool_use_id)?; +match result.action { + BashCheckpointAction::Checkpoint(paths) => { /* set edited_filepaths */ } + ... +} +if let Some(info) = result.captured_checkpoint { + agent_run_result.captured_checkpoint_id = Some(info.capture_id); +} +``` + +**Handler** (`git_ai_handlers.rs`): + +The checkpoint dispatch logic checks `captured_checkpoint_id` BEFORE the existing `allow_captured_async` gate. The `captured_checkpoint_id` field represents an already-prepared capture that bypasses the normal live/captured decision logic: + +```rust +if let Some(capture_id) = &agent_run_result.captured_checkpoint_id { + // Already prepared by bash tool — submit directly (fire-and-forget) + send_control_request(ControlRequest::CheckpointRun { + request: CheckpointRunRequest::Captured(CapturedCheckpointRunRequest { + repo_working_dir: repo_working_dir.clone(), + capture_id: capture_id.clone(), + }), + wait: Some(false), + })?; +} else if allow_captured_async { ... } else { + // Existing live checkpoint path +} +``` + +**Migration note:** The existing `BashCheckpointAction` enum and its variants (`TakePreSnapshot`, `Checkpoint(paths)`, `NoChanges`, `Fallback`) remain unchanged. The new `BashToolResult` wraps the action with an optional `CapturedCheckpointInfo`. All 8+ call sites in presets change from `match handle_bash_tool(...)` to `match handle_bash_tool(...).action`, with an additional check for `.captured_checkpoint`. The non-daemon fallback path continues to use `BashCheckpointAction` variants without captured checkpoints. + +### 5. Fallback Behavior + +| Scenario | Behavior | +|----------|----------| +| **Non-daemon mode** | Skip watermark query. Pre-hook only takes stat-snapshot (existing). Post-hook returns `edited_filepaths` for synchronous processing. No content capture. | +| **Daemon query failure** | Log warning, proceed without pre-hook content capture. Post-hook captured checkpoint still works on its own. | +| **Large working tree (>1000 stale files)** | Skip content capture, fall back to stat-diff + live checkpoint path. | +| **File read error** | Log warning, omit file from capture. Daemon handles the gap via existing fallback. | +| **Binary/large file (>10MB)** | Skip file in capture. Daemon handles via git diff fallback. | + +### 6. Testing Strategy + +| Test Type | What to Test | +|-----------|-------------| +| **Unit (bash_tool.rs)** | Watermark comparison logic; file content capture; `BashToolResult` construction; stale file detection | +| **Integration (daemon)** | Full pre/post flow with real daemon; verify captured checkpoints are queued and processed in order; watermark updates after checkpoint processing | +| **Benchmark** | Daemon watermark query round-trip stays under 10ms | +| **Fallback** | Graceful degradation: daemon unavailable, query timeout, large tree, binary files | + +### 7. File Change Summary + +| File | Change | +|------|--------| +| `src/daemon/control_api.rs` | Add `SnapshotWatermarks` request variant | +| `src/daemon.rs` | Add watermark state to per-family data; update watermarks during `apply_checkpoint_side_effect()`; handle `SnapshotWatermarks` request | +| `src/daemon/domain.rs` | Add `file_snapshot_watermarks` field to family state (if state lives here) | +| `src/commands/checkpoint_agent/bash_tool.rs` | New `BashToolResult`, `CapturedCheckpointInfo`; content capture logic; daemon watermark query in pre-hook; captured checkpoint creation in post-hook | +| `src/commands/checkpoint_agent/agent_presets.rs` | Update all presets to handle `BashToolResult`; set `captured_checkpoint_id` | +| `src/commands/checkpoint_agent/amp_preset.rs` | Same as above for Amp preset | +| `src/commands/checkpoint_agent/opencode_preset.rs` | Same as above for OpenCode preset | +| `src/authorship/working_log.rs` | Add `captured_checkpoint_id` to `AgentRunResult` | +| `src/commands/git_ai_handlers.rs` | Check `captured_checkpoint_id` and submit captured checkpoint | +| `tests/integration/bash_tool_conformance.rs` | New tests for watermark comparison, content capture, async flow | + +## Attribution Ordering + +**Pre-hook attribution concern:** When the pre-hook captures files as `CheckpointKind::Human`, it may re-attribute changes that were already attributed by a prior tool's checkpoint still queued in the daemon. This is acceptable because: + +1. The daemon processes checkpoints in queue order. The prior tool's checkpoint will be processed first, correctly attributing those changes to the tool. +2. The pre-hook's Human checkpoint processes second. Since the files haven't changed between the two checkpoints (the bash command hasn't run yet), the daemon will see no diff and the Human checkpoint becomes a no-op for those files. +3. The post-hook's AiAgent checkpoint processes third, correctly attributing the bash command's changes. + +The over-capture in step 2 is redundant work but produces correct final attribution. + +## Non-Goals + +- Changing the daemon's checkpoint queue ordering (already correct). +- Modifying the `prepare_captured_checkpoint()` pipeline (reused as-is). +- Supporting non-daemon mode with async checkpoints (non-daemon is being deprecated). +- Optimizing the watermark query with caching (can be added later if round-trip proves costly). diff --git a/src/commands/checkpoint_agent/agent_presets.rs b/src/commands/checkpoint_agent/agent_presets.rs index e5810e673..9459e832a 100644 --- a/src/commands/checkpoint_agent/agent_presets.rs +++ b/src/commands/checkpoint_agent/agent_presets.rs @@ -3,6 +3,9 @@ use crate::{ transcript::{AiTranscript, Message}, working_log::{AgentId, CheckpointKind}, }, + commands::checkpoint_agent::bash_tool::{ + self, Agent, BashCheckpointAction, HookEvent, ToolClass, + }, error::GitAiError, git::repository::find_repository_for_file, observability::log_error, @@ -76,6 +79,12 @@ impl AgentCheckpointPreset for ClaudePreset { .and_then(|v| v.as_str()) .ok_or_else(|| GitAiError::PresetError("cwd not found in hook_input".to_string()))?;
