+## Review integration (`entire review`)
+
+Codex review runs via `codex exec --skip-git-repo-check --json [-m <model>] [-c model_reasoning_effort=<level>] -` (prompt on stdin). **`codex exec` fires no lifecycle hooks**, which shapes the whole integration (see CLAUDE.md → `entire review` → "Codex specifics"):
+
+- **Skills are passed verbatim, not paraphrased.** Codex injects its installed-skill catalog into every exec session and loads the matching `SKILL.md`; configured skills use codex's `$name` / `$plugin:name` form (`DiscoverReviewSkills` in `discovery.go`). Native `codex exec review` is not used — it rejects a prompt under a scope flag and can't carry Entire's scope/per-run/checkpoint context.
+- **Live tokens come from the rollout file, not stdout.** `codex exec --json` carries `usage` only on the terminal `turn.completed`, and a review is a single turn. `review_tokens.go` resolves the rollout transcript by `thread_id` (from the `thread.started` envelope), tails it (the same `~/.codex/.../rollout-*-<thread-id>.jsonl` documented under Transcript above), and emits cumulative `Tokens` per `token_count` event — the source codex's interactive UI reads.
+- **No tagged review session.** Because no hook fires, codex's session is never tagged `KindAgentReview`. The fix manifest therefore sources codex from its **live run output** (`run.Buffer`), and `entire review fix` skill verification is advisory for codex (loose description match), not a hard block.

+//
+// Checkpoint refs need ONE deterministic destination, because the push-discovery
+// queue records only a ref (`{"ref": …}`) with no per-destination state: a ref is
+// removed from the queue once "the push" succeeds, so "the push" has to mean one
+// place. Relying on git's fan-out across a remote's several push URLs breaks that
+// in both directions — a single failing URL fails the whole invocation and no ref
+// unqueues even though some URLs took it, and an unreachable FIRST URL makes git
+// die() before it reaches any later URL at all.
+//
+// So when a remote carries more than one push URL we target its first push URL
+// directly (the one git itself would push to first) and ignore the rest. The
+// recovery fetch in fetchAndRebaseRefCommon uses the same target, so — unlike the
+// fan-out path, which reconciled the remote's FETCH url while pushing to its
+// pushurls — the URL we reconcile is finally the URL we push to.
+//
+// Consequences, deliberately accepted:
+//   - Checkpoint refs live in exactly one repository. Cloning that repository
+//     resolves them (its url becomes the clone's fetch URL); cloning a different
+//     mirror of the same code does not. Mirroring checkpoints to several
+//     repositories is what checkpoint_remote is for.
+//   - A first push URL that REJECTS a ref (non-fast-forward) no longer lets later
+//     URLs receive it. git would have carried on to them; we stop. That is the
+//     price of a deterministic destination, and it is the case the queue can
+//     actually reason about.
+//
+// The git-branch backend deliberately keeps git's fan-out: its v1 branch is a
+// single shared ref with no queue to keep coherent, and mirroring it to every
+// push URL is behavior users configure their remotes for.
+//
+// A single push URL keeps the remote NAME as the target rather than resolving it
+// to a URL, so the overwhelmingly common topology behaves exactly as before —
+// remote-tracking refs still update, output still says "origin", and no
+// URL-keyed promisor config appears.

Here's the core reason:\n\n**Attribution answers: \"what percentage of the new code in this commit was written by the agent?\"**\n\nDeleted lines don't exist in the final commit, so there's nothing to attribute. The metric measures lines that are *present* in the committed code — you can point at a line and say \"the agent wrote this\" or \"the human wrote this,\" but you can't point at a line that isn't there.\n\nConcretely, look at line 231:\n\n```go\n_, workAdded, _ := diffLines(baseContent, shadowContent)\ntotalAgentAndUserWork += workAdded\n```\n\nThe removed count is discarded (`_`). The `totalCommitted` denominator (line 326) is defined as:\n\n```go\ntotalCommitted := totalAgentAdded + pureUserAdded - pureUserRemoved\n```\n\nThis is \"net new lines added to the codebase.\" The percentage (`agentLinesInCommit / totalCommitted`) tells you what fraction of the surviving code came from the agent.\n\n**User deletions *are* partially tracked** — `HumanRemoved` captures when a user deletes agent-written lines, which reduces `agentLinesInCommit` (line 340). But agent deletions themselves don't appear anywhere because:\n\n1. A deletion doesn't produce attributable output — there's no line in the commit to claim credit for\n2. The metric would be misleading — an agent that deletes 500 lines of dead code and adds 1 line would show as \"mostly deletions,\" which doesn't tell you anything useful about who wrote the committed code\n3. It keeps the model simple — attribution is a ratio over lines that exist, avoiding the question of how to weight added vs deleted lines\n\nThe comments on lines 499-503 make this explicit: deletion-only commits get 0% attribution, by design.\n\nThere's a `TODO` on line 93 noting that binary file changes could be tracked separately, but no equivalent TODO for deleted lines — suggesting this was a deliberate design choice rather than an oversight.","type":"text"}]}

Here's the core reason:\n\n**Attribution answers: \"what percentage of the new code in this commit was written by the agent?\"**\n\nDeleted lines don't exist in the final commit, so there's nothing to attribute. The metric measures lines that are *present* in the committed code — you can point at a line and say \"the agent wrote this\" or \"the human wrote this,\" but you can't point at a line that isn't there.\n\nConcretely, look at line 231:\n\n```go\n_, workAdded, _ := diffLines(baseContent, shadowContent)\ntotalAgentAndUserWork += workAdded\n```\n\nThe removed count is discarded (`_`). The `totalCommitted` denominator (line 326) is defined as:\n\n```go\ntotalCommitted := totalAgentAdded + pureUserAdded - pureUserRemoved\n```\n\nThis is \"net new lines added to the codebase.\" The percentage (`agentLinesInCommit / totalCommitted`) tells you what fraction of the surviving code came from the agent.\n\n**User deletions *are* partially tracked** — `HumanRemoved` captures when a user deletes agent-written lines, which reduces `agentLinesInCommit` (line 340). But agent deletions themselves don't appear anywhere because:\n\n1. A deletion doesn't produce attributable output — there's no line in the commit to claim credit for\n2. The metric would be misleading — an agent that deletes 500 lines of dead code and adds 1 line would show as \"mostly deletions,\" which doesn't tell you anything useful about who wrote the committed code\n3. It keeps the model simple — attribution is a ratio over lines that exist, avoiding the question of how to weight added vs deleted lines\n\nThe comments on lines 499-503 make this explicit: deletion-only commits get 0% attribution, by design.\n\nThere's a `TODO` on line 93 noting that binary file changes could be tracked separately, but no equivalent TODO for deleted lines — suggesting this was a deliberate design choice rather than an oversight.","type":"text"}]}

There were no shadow branch checkpoints for this condensation. That means:\n\n1. `shadowRef` is nil → the code falls back to `shadowTree = headTree` (line 407 of `manual_commit_condensation.go`)\n2. `baseTree` = tree at `AttributionBaseCommit` (which should be the previous commit `f84785e5e`)\n3. `headTree` = tree at `b91ac0681`\n\nSince `shadowTree == headTree`, the `diffLines(shadowContent, headContent)` will always return 0 changes (they're identical). So the trace calculation collapses to:\n\n```\ntotalAgentAndUserWork = diffLines(base, head).added  // for the 2 files_touched\n```\n\nBut diffing `f84785e5e..b91ac0681` for those 2 files should yield 0 additions and 15 deletions.

Let me walk through what happened.\n\nThe 7th checkpoint (`c14692dbdbc6`) has wildly inflated numbers: `agent_lines: 36`, `human_added: 587`, `total_committed: 623` — for a commit that only **deletes 15 lines**.\n\nThe key: `checkpoints_count: 0`. There were no shadow branch checkpoints for this condensation. That means:\n\n1. `shadowRef` is nil → the code falls back to `shadowTree = headTree` (line 407 of `manual_commit_condensation.go`)\n2. `baseTree` = tree at `AttributionBaseCommit` (which should be the previous commit `f84785e5e`)\n3. `headTree` = tree at `b91ac0681`\n\nSince `shadowTree == headTree`, the `diffLines(shadowContent, headContent)` will always return 0 changes (they're identical). So the entire calculation collapses to:\n\n```\ntotalAgentAndUserWork = diffLines(base, head).added  // for the 2 files_touched\n```\n\nBut diffing `f84785e5e..b91ac0681` for those 2 files should yield 0 additions and 15 deletions. So where do 623 added lines come from?\n\n**The bug**: the `AttributionBaseCommit` wasn't the previous commit.

Here's what happened and what to do about it:\n\n---\n\n## The Bug\n\n`updateBaseCommitIfChanged` (line 1133-1151) updates `BaseCommit` but **never updates `AttributionBaseCommit`**:\n\n```go\nfunc (s *ManualCommitStrategy) updateBaseCommitIfChanged(...) {\n    if state.BaseCommit != newHead {\n        state.BaseCommit = newHead       // ✓ updated\n        // AttributionBaseCommit = ???    // ✗ NOT updated\n    }\n}\n```\n\nThis gets called at lines 649 and 675 when `shouldCondense` is false — i.e., when the session has no new content to condense into this commit (e.g., a user-only commit, or the session was idle with no checkpoints).\n\n**What happened with your commit**: Between the 6th and 7th polish commits, there was a commit where condensation was skipped for this session. `BaseCommit` advanced to the new HEAD, but `AttributionBaseCommit` stayed at the old value. Then when the 7th commit did condense, it diffed from the stale base → HEAD, producing the inflated 623 lines.\n\nThere's a second path too: if `condenseAndUpdateState` fails (line 1086-1093), it returns false without updating `AttributionBaseCommit`, but the state is still saved.\n\n## Fix Options\n\n**Quick fix** — update `AttributionBaseCommit` alongside `BaseCommit`:\n\n```go\nfunc (s *ManualCommitStrategy) updateBaseCommitIfChanged(...) {\n    if !state.Phase.IsActive() { return }\n    if state.BaseCommit != newHead {\n        state.BaseCommit = newHead\n        state.AttributionBaseCommit = newHead  // \u003c-- add this\n    }\n}\n```\n\n**But this might be wrong** — if the session has accumulated prompt attributions that haven't been condensed yet, resetting `AttributionBaseCommit` would lose that tracking window. We'd need to also clear `PromptAttributions` to stay consistent.\n\n## Better Investigation Plan\n\n1. **Add a log line** in `updateBaseCommitIfChanged` when `AttributionBaseCommit != BaseCommit` after the update — this would show exactly when drift occurs in production\n2. **Add a validation check** at condensation time: if `AttributionBaseCommit` is an ancestor of `BaseCommit` (not equal), log a warning with the gap size — we'd see exactly how far stale it got\n3. **Write a regression test**: create a session, make a commit that skips condensation (no new content), then make another that does condense — verify `AttributionBaseCommit` is correct\n\nWant me to implement the fix and the test?","type":"text"}]}

This caused `AttributionBaseCommit` to drift behind, making subsequent condensations diff against a stale base and inflate `human_added` with lines from unrelated prior commits.\n\n- **Fix**: Two one-line additions — `state.AttributionBaseCommit = newHead` alongside the existing `state.BaseCommit = newHead` in both functions (`manual_commit_hooks.go` lines ~1146 and ~1187).\n\n- **Test**: `TestManualCommit_AttributionStaleBase` — reproduces the exact production pattern: agent works → commit → unrelated commit while ACTIVE → agent works again → second commit shows inflated attribution.

It keeps the model simple — attribution is a ratio over lines that exist, avoiding the question of how to weight added vs deleted lines\n\nThe comments on lines 499-503 make this explicit: deletion-only commits get 0% attribution, by design.\n\nThere's a `TODO` on line 93 noting that binary file changes could be tracked separately, but no equivalent TODO for deleted lines — suggesting this was a deliberate design choice rather than an oversight."}],"stop_reason":"end_turn","stop_sequence":null,"usage":{"input_tokens":782,"cache_creation_input_tokens":1296,"cache_read_input_tokens":33894,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":1296},"output_tokens":1177,"service_tier":"standard","inference_geo":"not_available"},"context_management":{"applied_edits":[]}},"requestId":"req_011CZTEeN8vqFJSwofPZG3F2","type":"assistant","uuid":"496eaf27-f0f8-48ff-88fd-e33bfef2bdca","timestamp":"2026-03-27T08:03:48.136Z","userType":"external","entrypoint":"cli","cwd":"/repo/cli","sessionId":"466e2cb2-1cca-4296-8efd-ef4bb139d9c3","version":"2.1.85","gitBranch":"main","slug":"gentle-wishing-ladybug"}

That means:\n\n1. `shadowRef` is nil → the code falls back to `shadowTree = headTree` (line 407 of `manual_commit_condensation.go`)\n2. `baseTree` = tree at `AttributionBaseCommit` (which should be the previous commit `f84785e5e`)\n3. `headTree` = tree at `b91ac0681`\n\nSince `shadowTree == headTree`, the `diffLines(shadowContent, headContent)` will always return 0 changes (they're identical). So the trace calculation collapses to:\n\n```\ntotalAgentAndUserWork = diffLines(base, head).added  // for the 2 files_touched\n```\n\nBut diffing `f84785e5e..b91ac0681` for those 2 files should yield 0 additions and 15 deletions.

If `AttributionBaseCommit` were correctly set to the previous commit (`f84785e5e`), there'd be **zero** non-agent file changes, and `human_added` would be 0.\n\n**587 human_added means the `AttributionBaseCommit` was stale** — pointing far back in history, not to the previous commit. The \"human lines\" are actually all the additions across dozens of files that changed between that old base and HEAD — other people's commits, merges, etc., all counted as \"human added.\"\n\nSame for `agent_lines: 36` — that's `diffLines(staleBase, head).added` for the 2 `filesTouched` files. Since those files changed a lot across the full polish series, the stale base produces a large diff even though this specific commit only deletes lines.\n\nThe session state file is gone so I can't verify which commit it was stuck on, but the numbers are consistent with the attribution base never advancing past the original session start (before all 7 polish commits). Likely the state update at `manual_commit_hooks.go:1101` didn't stick for this condensation — possibly because `checkpoints_count: 0` hit a different code path that skipped the state update."}],"stop_reason":"end_turn","stop_sequence":null,"usage":{"input_tokens":3,"cache_creation_input_tokens":481,"cache_read_input_tokens":75472,"output_tokens":4417,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":481,"ephemeral_5m_input_tokens":0},"inference_geo":"","iterations":[],"speed":"standard"}},"requestId":"req_011CZTGxAJmfHmmCDHVK6DUp","type":"assistant","uuid":"3e50d571-38d7-4e33-9724-8839e12dd427","timestamp":"2026-03-27T08:34:43.108Z","userType":"external","entrypoint":"cli","cwd":"/repo/cli","sessionId":"466e2cb2-1cca-4296-8efd-ef4bb139d9c3","version":"2.1.85","gitBranch":"main","slug":"gentle-wishing-ladybug"}

Let me create a comprehensive summary:\n\n## Bug Analysis Report: AttributionBaseCommit Becomes Stale\n\n### Critical Finding\n\nI've identified a **stale state scenario** where `AttributionBaseCommit` is not updated when condensation is skipped, particularly when `StepCount == 0` (no shadow branch checkpoints). This causes incorrect attribution calculations in subsequent condensations.\n\n---\n\n### Code Path Analysis\n\n#### 1. **PostCommit Handler Flow** (`manual_commit_hooks.go:629-651`)\n\nWhen PostCommit is triggered with a trailer:\n\n```go\nHandleCondense() / HandleCondenseIfFilesTouched()\n  ↓\n  shouldCondense = shouldCondenseWithOverlapCheck(...)\n  ↓\n  if shouldCondense {\n    h.condensed = h.s.condenseAndUpdateState(...)  // Line 642, 668\n  } else {\n    h.s.updateBaseCommitIfChanged(...)             // Line 649, 675\n  }\n```\n\n**Key Issue**: When `shouldCondense` is FALSE, `updateBaseCommitIfChanged` is called instead of `condenseAndUpdateState`. This is where the bug occurs.\n\n#### 2. **updateBaseCommitIfChanged** (`manual_commit_hooks.go:1129-1151`)\n\n```go\nfunc (s *ManualCommitStrategy) updateBaseCommitIfChanged(...) {\n  if !state.Phase.IsActive() {\n    return // EARLY RETURN: IDLE/ENDED sessions NOT updated\n  }\n  if state.BaseCommit != newHead {\n    state.BaseCommit = newHead\n    // NOTE: state.AttributionBaseCommit is NOT updated here!\n  }\n}\n```\n\n**Critical Gap**: \n- `BaseCommit` is updated for ACTIVE sessions\n- **`AttributionBaseCommit` is NEVER updated** ✗\n- IDLE/ENDED sessions don't even get `BaseCommit` updated\n- The state is saved later in `postCommitProcessSession` line 1058\n\n#### 3. **When does this matter?** - Condensation After 0 Checkpoints\n\nIf the session has `StepCount == 0` (no SaveStep called yet, no shadow branch):\n\n1. **Scenario**: Agent makes mid-turn commit with no SaveStep\n   - `state.StepCount = 0` (no shadow branch)\n   - `state.BaseCommit = commitA`\n   - `state.AttributionBaseCommit = commitA` (set at session init)\n   \n2. **First PostCommit**:\n   - `shouldCondenseWithOverlapCheck` returns FALSE (no shadow branch, no prior checkpoints)\n   - `updateBaseCommitIfChanged` is called\n   - `BaseCommit` → `commitB` (updated)\n   - **`AttributionBaseCommit` stays `commitA`** ✓ (correct)\n\n3. **Subsequent commits + condensation** (e.g., SaveEnd or later PostCommit with trailer):\n   - `CondenseSession` is called\n   - At line 191-193 in `manual_commit_condensation.go`:\n     ```go\n     attrBase := state.AttributionBaseCommit  // Still commitA\n     if attrBase == \"\" {\n       attrBase = state.BaseCommit  // Would be commitB or newer\n     }\n     ```\n   - Attribution uses `commitA` when it should account for changes between `commitA` and current HEAD\n\n---\n\n### The Bug Manifests in Two Ways\n\n#### **Bug #1: No Shadow Branch + No Condensation on First Commit**\n\n**Scenario**: Session created, agent makes mid-turn commit with no SaveStep.\n\nPath:\n1. PostCommit called with trailer\n2. `shouldCondenseWithOverlapCheck` → FALSE (no shadow branch, filesTouchedBefore is empty or doesn't match)\n3. `updateBaseCommitIfChanged` called → **BaseCommit updated, AttributionBaseCommit NOT updated**\n4. State saved with stale `AttributionBaseCommit`\n\nResult: Next condensation has wrong attribution base.\n\n#### **Bug #2: CondenseSession Fails During Condensation**\n\n**Scenario**: `condenseAndUpdateState` calls `CondenseSession`, which FAILS.\n\nPath in `condenseAndUpdateState` (line 1086-1093):\n```go\nresult, err := s.CondenseSession(...)\nif err != nil {\n  logging.Warn(...)  // Log warning\n  return false       // RETURN FALSE WITHOUT UPDATING ATTRIBUTION BASE\n}\n\n// Never reached if error occurs:\nstate.BaseCommit = newHead\nstate.AttributionBaseCommit = newHead  // Line 1101\n```\n\n**Critical Issue**: If `CondenseSession` fails:\n- `condenseAndUpdateState` returns FALSE\n- Handler `h.condensed = false`\n- Lines 1098-1104 (BaseCommit and AttributionBaseCommit updates) are **NEVER executed**\n- `postCommitProcessSession` still calls `saveSessionState` at line 1058\n- **State is saved with OLD, stale `AttributionBaseCommit`** and updated `FilesTouched` from carry-forward logic (lines 1022-1046)\n\n---\n\n### Root Cause Analysis\n\nThe code assumes that `AttributionBaseCommit` only changes during successful condensation, but:\n\n1. **ACTIVE sessions** can have `BaseCommit` updated via `updateBaseCommitIfChanged` without updating `AttributionBaseCommit`\n2. **Condensation failures** return early without updating `AttributionBaseCommit`\n3. **State is always saved** regardless of condensation success (line 1058), creating a mismatch between `BaseCommit` and `AttributionBaseCommit`\n\n### Error Paths That Skip Attribution Update\n\n1. **Line 1087-1092**: `CondenseSession` error → return FALSE → no state update in lines 1098-1104\n2. **Line 649, 675**: `shouldCondense = FALSE` → `updateBaseCommitIfChanged` called → NO AttributionBaseCommit update\n3. **Line 1137-1142**: IDLE/ENDED sessions → `updateBaseCommitIfChanged` returns early → neither BaseCommit nor AttributionBaseCommit updated (acceptable, but worth noting)\n\n---\n\n### Specific Code Paths with `checkpoints_count == 0`\n\nWhen `state.StepCount == 0` (no shadow branch):\n\n1. **`manual_commit_condensation.go:129-147`**:\n   - If `hasShadowBranch == false`, goes to `extractSessionDataFromLiveTranscript`\n   - This succeeds if `TranscriptPath` is available\n   - Condensation can proceed even with 0 checkpoints\n\n2. **`manual_commit_hooks.go:680-722`** (`shouldCondenseWithOverlapCheck`):\n   - If `filesTouchedBefore` is empty, returns FALSE (no condensation)\n   - This is correct, BUT means `AttributionBaseCommit` won't be updated\n\n3. **`manual_commit_hooks.go:1022-1046`** (carry-forward logic):\n   - Only executes if `handler.condensed == true`\n   - If `shouldCondense == FALSE`, this block is skipped\n   - FilesTouched is NOT carried forward (correct behavior)\n\n---\n\n### Carry-Forward and Attribution Misalignment Risk\n\nIn `postCommitProcessSession` (lines 1016-1047):\n\n```go\nif handler.condensed {\n  remainingFiles := filesWithRemainingAgentChanges(...)\n  state.FilesTouched = remainingFiles  // Updated for next commit\n  // ...\n}\n```\n\nIf carry-forward logic executes (condensation happened):\n- `FilesTouched` is recalculated and updated\n- **But if carry-forward fails to execute, `FilesTouched` stays from before**\n- Meanwhile, `AttributionBaseCommit` should point to the base of those files\n\nWhen `condensation == false`:\n- `FilesTouched` is NOT updated (stays from before)\n- `AttributionBaseCommit` is NOT updated\n- This is internally consistent for IDLE/ENDED, but **risky for ACTIVE** if `BaseCommit` changed\n\n---\n\n### Session State Save Path (Always Executes)\n\nLine 1056-1063:\n```go\n// Save the updated state\nif err := s.saveSessionState(ctx, state); err != nil {\n  logging.Warn(...)  // Log warning but continue\n}\n```\n\n**Important**: Even if `saveSessionState` errors, the code continues. The state may be partially saved or not saved at all, and the hook returns success (nil error from PostCommit).\n\nThis means: **If saveSessionState fails, AttributionBaseCommit might not be persisted, but the hook doesn't report failure**.\n\n---\n\n### Failure Scenarios Summary\n\n| Scenario | BaseCommit | AttributionBaseCommit | FilesTouched | Saved? | Bug? |\n|----------|-----------|----------------------|--------------|--------|------|\n| No shadow, no condense | Updated | Not updated | Same | Yes | YES - mismatch |\n| CondenseSession fails | Not updated | Not updated | May change | Partial | YES - inconsistent |\n| Normal condense + carry | Updated | Updated | Recalculated | Yes | No |\n| saveSessionState fails | In memory only | In memory only | In memory | No | YES - not persisted |\n| IDLE/ENDED no condense | Not updated | Not updated | Same | Yes | OK for these phases |\n\n---\n\n### Test Files Confirming the Bug\n\nThe test at `/repo/cli/cmd/trace/cli/strategy/manual_commit_test.go:2227` shows:\n```go\nstate := &SessionState{\n  SessionID:             \"test-no-shadow\",\n  BaseCommit:            initialHash.String(),\n  AttributionBaseCommit: initialHash.String(),  // Must be set manually in test\n  ...\n}\n```\n\nThis test manually sets `AttributionBaseCommit`, indicating the code doesn't reliably set it in all paths.\n\n---\n\n### Recommendations\n\n1. **Update `updateBaseCommitIfChanged`** to also update `AttributionBaseCommit` when `BaseCommit` changes (or add a separate update call)\n2. **Track condensation success/failure** separately from state updates\n3. **Handle CondenseSession errors** by updating `AttributionBaseCommit` before returning\n4. **Test scenarios**: Mid-turn commit with 0 checkpoints + subsequent condensation\n5. **Add validation**: Check that `AttributionBaseCommit` ≤ `BaseCommit` (in commit history)\n\n---\n\n### Key Files to Review\n\n- `/repo/cli/cmd/trace/cli/strategy/manual_commit_hooks.go` lines 629-1127 (PostCommit flow)\n- `/repo/cli/cmd/trace/cli/strategy/manual_commit_condensation.go` lines 103-286 (CondenseSession)\n- `/repo/cli/cmd/trace/cli/strategy/manual_commit_hooks.go` lines 1056-1070 (State save point)"}]}]},"uuid":"e738d629-6663-41ce-9967-756311390c5b","timestamp":"2026-03-27T08:38:55.459Z","toolUseResult":{"status":"completed","prompt":"I'm investigating a bug where the `AttributionBaseCommit` in session state becomes stale, leading to incorrect attribution numbers.

This is where the bug occurs.\n\n#### 2. **updateBaseCommitIfChanged** (`manual_commit_hooks.go:1129-1151`)\n\n```go\nfunc (s *ManualCommitStrategy) updateBaseCommitIfChanged(...) {\n  if !state.Phase.IsActive() {\n    return // EARLY RETURN: IDLE/ENDED sessions NOT updated\n  }\n  if state.BaseCommit != newHead {\n    state.BaseCommit = newHead\n    // NOTE: state.AttributionBaseCommit is NOT updated here!\n  }\n}\n```\n\n**Critical Gap**: \n- `BaseCommit` is updated for ACTIVE sessions\n- **`AttributionBaseCommit` is NEVER updated** ✗\n- IDLE/ENDED sessions don't even get `BaseCommit` updated\n- The state is saved later in `postCommitProcessSession` line 1058\n\n#### 3. **When does this matter?** - Condensation After 0 Checkpoints\n\nIf the session has `StepCount == 0` (no SaveStep called yet, no shadow branch):\n\n1. **Scenario**: Agent makes mid-turn commit with no SaveStep\n   - `state.StepCount = 0` (no shadow branch)\n   - `state.BaseCommit = commitA`\n   - `state.AttributionBaseCommit = commitA` (set at session init)\n   \n2. **First PostCommit**:\n   - `shouldCondenseWithOverlapCheck` returns FALSE (no shadow branch, no prior checkpoints)\n   - `updateBaseCommitIfChanged` is called\n   - `BaseCommit` → `commitB` (updated)\n   - **`AttributionBaseCommit` stays `commitA`** ✓ (correct)\n\n3. **Subsequent commits + condensation** (e.g., SaveEnd or later PostCommit with trailer):\n   - `CondenseSession` is called\n   - At line 191-193 in `manual_commit_condensation.go`:\n     ```go\n     attrBase := state.AttributionBaseCommit  // Still commitA\n     if attrBase == \"\" {\n       attrBase = state.BaseCommit  // Would be commitB or newer\n     }\n     ```\n   - Attribution uses `commitA` when it should account for changes between `commitA` and current HEAD\n\n---\n\n### The Bug Manifests in Two Ways\n\n#### **Bug #1: No Shadow Branch + No Condensation on First Commit**\n\n**Scenario**: Session created, agent makes mid-turn commit with no SaveStep.\n\nPath:\n1. PostCommit called with trailer\n2. `shouldCondenseWithOverlapCheck` → FALSE (no shadow branch, filesTouchedBefore is empty or doesn't match)\n3. `updateBaseCommitIfChanged` called → **BaseCommit updated, AttributionBaseCommit NOT updated**\n4. State saved with stale `AttributionBaseCommit`\n\nResult: Next condensation has wrong attribution base.\n\n#### **Bug #2: CondenseSession Fails During Condensation**\n\n**Scenario**: `condenseAndUpdateState` calls `CondenseSession`, which FAILS.\n\nPath in `condenseAndUpdateState` (line 1086-1093):\n```go\nresult, err := s.CondenseSession(...)\nif err != nil {\n  logging.Warn(...)  // Log warning\n  return false       // RETURN FALSE WITHOUT UPDATING ATTRIBUTION BASE\n}\n\n// Never reached if error occurs:\nstate.BaseCommit = newHead\nstate.AttributionBaseCommit = newHead  // Line 1101\n```\n\n**Critical Issue**: If `CondenseSession` fails:\n- `condenseAndUpdateState` returns FALSE\n- Handler `h.condensed = false`\n- Lines 1098-1104 (BaseCommit and AttributionBaseCommit updates) are **NEVER executed**\n- `postCommitProcessSession` still calls `saveSessionState` at line 1058\n- **State is saved with OLD, stale `AttributionBaseCommit`** and updated `FilesTouched` from carry-forward logic (lines 1022-1046)\n\n---\n\n### Root Cause Analysis\n\nThe code assumes that `AttributionBaseCommit` only changes during successful condensation, but:\n\n1. **ACTIVE sessions** can have `BaseCommit` updated via `updateBaseCommitIfChanged` without updating `AttributionBaseCommit`\n2. **Condensation failures** return early without updating `AttributionBaseCommit`\n3. **State is always saved** regardless of condensation success (line 1058), creating a mismatch between `BaseCommit` and `AttributionBaseCommit`\n\n### Error Paths That Skip Attribution Update\n\n1. **Line 1087-1092**: `CondenseSession` error → return FALSE → no state update in lines 1098-1104\n2. **Line 649, 675**: `shouldCondense = FALSE` → `updateBaseCommitIfChanged` called → NO AttributionBaseCommit update\n3. **Line 1137-1142**: IDLE/ENDED sessions → `updateBaseCommitIfChanged` returns early → neither BaseCommit nor AttributionBaseCommit updated (acceptable, but worth noting)\n\n---\n\n### Specific Code Paths with `checkpoints_count == 0`\n\nWhen `state.StepCount == 0` (no shadow branch):\n\n1. **`manual_commit_condensation.go:129-147`**:\n   - If `hasShadowBranch == false`, goes to `extractSessionDataFromLiveTranscript`\n   - This succeeds if `TranscriptPath` is available\n   - Condensation can proceed even with 0 checkpoints\n\n2. **`manual_commit_hooks.go:680-722`** (`shouldCondenseWithOverlapCheck`):\n   - If `filesTouchedBefore` is empty, returns FALSE (no condensation)\n   - This is correct, BUT means `AttributionBaseCommit` won't be updated\n\n3. **`manual_commit_hooks.go:1022-1046`** (carry-forward logic):\n   - Only executes if `handler.condensed == true`\n   - If `shouldCondense == FALSE`, this block is skipped\n   - FilesTouched is NOT carried forward (correct behavior)\n\n---\n\n### Carry-Forward and Attribution Misalignment Risk\n\nIn `postCommitProcessSession` (lines 1016-1047):\n\n```go\nif handler.condensed {\n  remainingFiles := filesWithRemainingAgentChanges(...)\n  state.FilesTouched = remainingFiles  // Updated for next commit\n  // ...\n}\n```\n\nIf carry-forward logic executes (condensation happened):\n- `FilesTouched` is recalculated and updated\n- **But if carry-forward fails to execute, `FilesTouched` stays from before**\n- Meanwhile, `AttributionBaseCommit` should point to the base of those files\n\nWhen `condensation == false`:\n- `FilesTouched` is NOT updated (stays from before)\n- `AttributionBaseCommit` is NOT updated\n- This is internally consistent for IDLE/ENDED, but **risky for ACTIVE** if `BaseCommit` changed\n\n---\n\n### Session State Save Path (Always Executes)\n\nLine 1056-1063:\n```go\n// Save the updated state\nif err := s.saveSessionState(ctx, state); err != nil {\n  logging.Warn(...)  // Log warning but continue\n}\n```\n\n**Important**: Even if `saveSessionState` errors, the code continues. The state may be partially saved or not saved at all, and the hook returns success (nil error from PostCommit).\n\nThis means: **If saveSessionState fails, AttributionBaseCommit might not be persisted, but the hook doesn't report failure**.\n\n---\n\n### Failure Scenarios Summary\n\n| Scenario | BaseCommit | AttributionBaseCommit | FilesTouched | Saved? | Bug? |\n|----------|-----------|----------------------|--------------|--------|------|\n| No shadow, no condense | Updated | Not updated | Same | Yes | YES - mismatch |\n| CondenseSession fails | Not updated | Not updated | May change | Partial | YES - inconsistent |\n| Normal condense + carry | Updated | Updated | Recalculated | Yes | No |\n| saveSessionState fails | In memory only | In memory only | In memory | No | YES - not persisted |\n| IDLE/ENDED no condense | Not updated | Not updated | Same | Yes | OK for these phases |\n\n---\n\n### Test Files Confirming the Bug\n\nThe test at `/repo/cli/cmd/entire/cli/strategy/manual_commit_test.go:2227` shows:\n```go\nstate := &SessionState{\n  SessionID:             \"test-no-shadow\",\n  BaseCommit:            initialHash.String(),\n  AttributionBaseCommit: initialHash.String(),  // Must be set manually in test\n  ...\n}\n```\n\nThis test manually sets `AttributionBaseCommit`, indicating the code doesn't reliably set it in all paths.\n\n---\n\n### Recommendations\n\n1. **Update `updateBaseCommitIfChanged`** to also update `AttributionBaseCommit` when `BaseCommit` changes (or add a separate update call)\n2. **Track condensation success/failure** separately from state updates\n3. **Handle CondenseSession errors** by updating `AttributionBaseCommit` before returning\n4. **Test scenarios**: Mid-turn commit with 0 checkpoints + subsequent condensation\n5. **Add validation**: Check that `AttributionBaseCommit` ≤ `BaseCommit` (in commit history)\n\n---\n\n### Key Files to Review\n\n- `/repo/cli/cmd/entire/cli/strategy/manual_commit_hooks.go` lines 629-1127 (PostCommit flow)\n- `/repo/cli/cmd/entire/cli/strategy/manual_commit_condensation.go` lines 103-286 (CondenseSession)\n- `/repo/cli/cmd/entire/cli/strategy/manual_commit_hooks.go` lines 1056-1070 (State save point)"}],"totalDurationMs":61427,"totalTokens":84177,"totalToolUseCount":29,"usage":{"input_tokens":5,"cache_creation_input_tokens":1028,"cache_read_input_tokens":80434,"output_tokens":2710,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":0,"ephemeral_5m_input_tokens":1028},"inference_geo":"","iterations":[],"speed":"standard"}},"sourceToolAssistantUUID":"9dbb00b7-7031-42b0-b1e5-1baa4c881e20","userType":"external","entrypoint":"cli","cwd":"/repo/cli","sessionId":"466e2cb2-1cca-4296-8efd-ef4bb139d9c3","version":"2.1.85","gitBranch":"main","slug":"gentle-wishing-ladybug"}

Here's what happened and what to do about it:\n\n---\n\n## The Bug\n\n`updateBaseCommitIfChanged` (line 1133-1151) updates `BaseCommit` but **never updates `AttributionBaseCommit`**:\n\n```go\nfunc (s *ManualCommitStrategy) updateBaseCommitIfChanged(...) {\n    if state.BaseCommit != newHead {\n        state.BaseCommit = newHead       // ✓ updated\n        // AttributionBaseCommit = ???    // ✗ NOT updated\n    }\n}\n```\n\nThis gets called at lines 649 and 675 when `shouldCondense` is false — i.e., when the session has no new content to condense into this commit (e.g., a user-only commit, or the session was idle with no checkpoints).\n\n**What happened with your commit**: Between the 6th and 7th polish commits, there was a commit where condensation was skipped for this session. `BaseCommit` advanced to the new HEAD, but `AttributionBaseCommit` stayed at the old value. Then when the 7th commit did condense, it diffed from the stale base → HEAD, producing the inflated 623 lines.\n\nThere's a second path too: if `condenseAndUpdateState` fails (line 1086-1093), it returns false without updating `AttributionBaseCommit`, but the state is still saved.\n\n## Fix Options\n\n**Quick fix** — update `AttributionBaseCommit` alongside `BaseCommit`:\n\n```go\nfunc (s *ManualCommitStrategy) updateBaseCommitIfChanged(...) {\n    if !state.Phase.IsActive() { return }\n    if state.BaseCommit != newHead {\n        state.BaseCommit = newHead\n        state.AttributionBaseCommit = newHead  // <-- add this\n    }\n}\n```\n\n**But this might be wrong** — if the session has accumulated prompt attributions that haven't been condensed yet, resetting `AttributionBaseCommit` would lose that tracking window. We'd need to also clear `PromptAttributions` to stay consistent.\n\n## Better Investigation Plan\n\n1. **Add a log line** in `updateBaseCommitIfChanged` when `AttributionBaseCommit != BaseCommit` after the update — this would show exactly when drift occurs in production\n2. **Add a validation check** at condensation time: if `AttributionBaseCommit` is an ancestor of `BaseCommit` (not equal), log a warning with the gap size — we'd see exactly how far stale it got\n3. **Write a regression test**: create a session, make a commit that skips condensation (no new content), then make another that does condense — verify `AttributionBaseCommit` is correct\n\nWant me to implement the fix and the test?"}],"stop_reason":"end_turn","stop_sequence":null,"usage":{"input_tokens":1,"cache_creation_input_tokens":1178,"cache_read_input_tokens":84706,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":1178},"output_tokens":653,"service_tier":"standard","inference_geo":"not_available"},"context_management":{"applied_edits":[]}},"requestId":"req_011CZTHQWJXNTYD6JfBSpxRb","type":"assistant","uuid":"f5ebe29f-357d-476a-bc12-d0c379e2a305","timestamp":"2026-03-27T08:39:37.044Z","userType":"external","entrypoint":"cli","cwd":"/repo/cli","sessionId":"466e2cb2-1cca-4296-8efd-ef4bb139d9c3","version":"2.1.85","gitBranch":"main","slug":"gentle-wishing-ladybug"}

Here's the complete infrastructure breakdown:\n\n### 1. **Test Environment Setup** \n**File:** `/repo/cli/cmd/trace/cli/integration_test/testenv.go`\n\n#### Key Structures:\n- **`TestEnv`** - Main test environment struct that manages:\n  - `RepoDir` - Isolated git repository for testing\n  - `ClaudeProjectDir`, `GeminiProjectDir`, `OpenCodeProjectDir` - Agent project directories\n  - `SessionCounter` - Tracks session creation for unique IDs\n\n#### Factory Functions:\n- **`NewTestEnv(t)`** - Creates basic isolated environment without git initialization\n- **`NewRepoEnv creates a TestEnv with an initialized git repo and Trace-Checkpoint trailer present)\n  - This is what tests use instead of raw `git commit`\n\n- **`GitCommitWithShadowHooksAsAgent(message, files...)`** - Like above but with `ENTIRE_TEST_TTY=0` (simulates agent subprocess)\n\n### 2. **Session and Transcript Simulation**\n**File:** `/repo/cli/cmd/trace/cli/integration_test/hooks.go`\n\n#### Session Structure:\n```go\ntype Session struct {\n    ID                string                  // e.g., \"test-session-1\"\n    TranscriptPath    string                  // .trace/tmp/test-session-1.jsonl\n    TranscriptBuilder *TranscriptBuilder      // Helper for building transcript JSON\n    env               *TestEnv                // Reference back to test env\n}\n```\n\n#### Session Creation & Lifecycle:\n- **`env.NewSession()`** - Creates new session with auto-incrementing ID\n  - Generates path: `.trace/tmp/test-session-N.jsonl`\n  - Returns Session struct with TranscriptBuilder ready\n\n- **`session.CreateTranscript(prompt, changes []FileChange)`** - Writes JSONL transcript\n  - Takes a user prompt and array of FileChange{Path, Content}\n  - Adds user message, assistant response, tool uses (mcp__acp__Write), tool results\n  - Writes to session's TranscriptPath\n\n#### Hook Simulation (via HookRunner):\n- **`env.SimulateUserPromptSubmit(sessionID)`** - Simulates Claude Code user-prompt-submit hook\n  - Triggers attribution calculation at prompt start\n  - Captures pre-prompt state (untracked files)\n  \n- **`env.SimulateStop(sessionID, transcriptPath)`** - Simulates stop hook\n  - Called after SaveStep to complete checkpoint\n  - Reads from transcriptPath to determine what was saved\n\n### 3. **Attribution Tests in Integration Tests**\n**File:** `/repo/cli/cmd/trace/cli/integration_test/attribution_test.go`\n\n#### Test Pattern: `TestManualCommit_Attribution` (lines 24-211)\nThis is the **complete integration test** for the full attribution flow:\n\n```\n1. env.InitRepo() → Initialize git repo\n2. env.WriteFile(\"main.go\", content) + env.GitAdd() + env.GitCommit() → Initial commit\n3. env.InitTrace() → Initialize .trace directory\n\n[CHECKPOINT 1 - Agent Work]\n4. session = env.NewSession() → Create session\n5. env.SimulateUserPromptSubmit(session.ID) → Attribution calculation hook\n6. env.WriteFile(\"main.go\", agentContent) → Agent adds function\n7. session.CreateTranscript(prompt, fileChanges) → Write transcript\n8. env.SimulateStop(session.ID, session.TranscriptPath) → Complete checkpoint\n\n[USER EDITS between checkpoints]\n9. env.WriteFile(\"main.go\", userContent) → User adds 5 lines of comments\n\n[CHECKPOINT 2 - New Prompt]\n10. env.SimulateUserPromptSubmit(session.ID) → Attribution calculated again\n11. env.WriteFile(\"main.go\", checkpoint2Content) → Agent adds more code\n12. session.CreateTranscript(prompt2, fileChanges2) → New transcript\n13. env.SimulateStop(session.ID, session.TranscriptPath) → Complete checkpoint 2\n\n[USER COMMITS - Triggers Condensation]\n14. env.GitCommitWithShadowHooks(\"Add functions\", \"main.go\") → CRITICAL: runs hooks\n15. repo.CommitObject(headHash) → Get commit\n16. trailers.ParseCheckpoint(message) → Extract checkpoint ID from trailer\n\n[VERIFY ATTRIBUTION]\n17. repo.Reference(paths.MetadataBranchName) → Get trace/checkpoints/v1 branch\n18. tree.File(SessionMetadataPath(checkpointID)) → Read 0/metadata.json\n19. Unmarshal into checkpoint.CommittedMetadata → Parse JSON\n20. Assert metadata.InitialAttribution fields are correct\n```\n\n#### Key Assertions Pattern:\n```go\nattr := metadata.InitialAttribution\n// Expected: agent=13 lines, human=5 lines, total=18\nif attr.HumanAdded != 5 {\n    t.Errorf(\"HumanAdded = %d, want 5\", attr.HumanAdded)\n}\nif attr.AgentPercentage <= 0 || attr.AgentPercentage >= 100 {\n    t.Errorf(\"AgentPercentage = %.1f%%, should be between 0 and 100\", attr.AgentPercentage)\n}\n```\n\n#### Test Variants:\n1. **`TestManualCommit_Attribution`** (lines 24-211) - Main flow with mixed agent/user edits\n2. **`TestManualCommit_AttributionDeletionOnly`** (lines 213-353) - Tests deletion-only commits\n   - Expects `AgentLines=0`, `HumanAdded=0`, `TotalCommitted=0`, `AgentPercentage=0`\n3. **`TestManualCommit_AttributionNoDoubleCount`** (lines 364-517) - **REGRESSION TEST**\n   - **Bug scenario:** PromptAttributions not cleared after condensation\n   - First cycle: agent 4 lines, user 2 lines → commit\n   - Second cycle: agent 3 lines, user 1 line → expect 1, not 3 (would be double-counted)\n   - **Critical assertion:** `if attr2.HumanAdded != 1 { t.Error(\"should NOT double-count\") }`\n\n#### Helper Functions:\n- **`getAttributionFromMetadata(t, repo, checkpointID)`** - Reads metadata.json from sessions branch\n- **`SessionMetadataPath(checkpointID)`** - Returns path to session-level metadata\n- **`CheckpointSummaryPath(checkpointID)`** - Returns path to root metadata\n\n### 4. **Unit Tests for Condensation (CondenseSession)**\n**File:** `/repo/cli/cmd/trace/cli/strategy/manual_commit_test.go`\n\n#### Key Condensation Tests:\n1. **`TestCondenseSession_IncludesInitialAttribution`** (lines 1971-2156)\n   - Sets up git repo manually using go-git\n   - Creates initial commit\n   - Calls `s.SaveStep()` to create shadow branch\n   - User edits file\n   - Calls `s.CondenseSession(repo, checkpointID, state, nil)`\n   - Verifies `result.CheckpointID` equals input ID\n   - Reads metadata from `trace/checkpoints/v1` branch\n   - Verifies `metadata.InitialAttribution` is populated\n\n2. **`TestCondenseSession_AttributionWithoutShadowBranch`** (lines 2159+)\n   - Tests mid-turn commit (agent commits before SaveStep)\n   - No shadow branch exists\n   - Verifies attribution still calculated using HEAD as base\n\n3. **`TestCondenseSession_AttributionWithoutShadowBranch_MixedHumanAgent`** (lines 2309+)\n   - Similar but with more complex mixed edits\n\n#### Unit Test Pattern:\n```go\ndir := t.TempDir()\nrepo, _ := git.PlainInit(dir, false)\nworktree, _ := repo.Worktree()\n\n// Create initial commit\nos.WriteFile(filepath.Join(dir, \"file.go\"), content, 0o644)\nworktree.Add(\"file.go\")\nworktree.Commit(\"Initial\", &git.CommitOptions{...})\n\nt.Chdir(dir)\ns := &ManualCommitStrategy{}\n\n// Create metadata dir with transcript\nmetadataDir := \".trace/metadata/\" + sessionID\nos.MkdirAll(metadataDir, 0o755)\nos.WriteFile(filepath.Join(metadataDir, \"transcript.jsonl\"), transcript, 0o644)\n\n// Simulate SaveStep → creates shadow branch\ns.SaveStep(context.Background(), StepContext{...})\n\n// User edits\nos.WriteFile(testFile, humanEditedContent, 0o644)\nworktree.Add(\"test.go\")\nworktree.Commit(\"User commit\", &git.CommitOptions{...})\n\n// Load session state\nstate, _ := s.loadSessionState(context.Background(), sessionID)\n\n// Condense\ncheckpointID := id.MustCheckpointID(\"a1b2c3d4e5f6\")\nresult, _ := s.CondenseSession(context.Background(), repo, checkpointID, state, nil)\n\n// Verify\nsessionsRef, _ := repo.Reference(plumbing.NewBranchReferenceName(paths.MetadataBranchName), true)\nsessionsCommit, _ := repo.CommitObject(sessionsRef.Hash())\ntree, _ := sessionsCommit.Tree()\nmetadataFile, _ := tree.File(checkpointID.Path() + \"/0/\" + paths.MetadataFileName)\ncontent, _ := metadataFile.Contents()\njson.Unmarshal([]byte(content), &metadata)\n\n// Assert attribution fields\n```\n\n### 5. **Attribution Data Structures**\n**Location:** `cmd/trace/cli/checkpoint/committed.go`\n\n#### CommittedMetadata (session-level metadata):\n```go\ntype CommittedMetadata struct {\n    InitialAttribution *InitialAttribution `json:\"initial_attribution\"`\n    // ... other fields\n}\n\ntype InitialAttribution struct {\n    AgentLines      int     `json:\"agent_lines\"`\n    HumanAdded      int     `json:\"human_added\"`\n    HumanModified   int     `json:\"human_modified\"`\n    HumanRemoved    int     `json:\"human_removed\"`\n    TotalCommitted  int     `json:\"total_committed\"`\n    AgentPercentage float64 `json:\"agent_percentage\"`\n}\n```\n\n### 6. **Key Test Utilities & Paths**\n- **`paths.MetadataBranchName`** = `\"trace/checkpoints/v1\"`\n- **`paths.MetadataFileName`** = `\"metadata.json\"`\n- **`paths.TranscriptFileName`** = `\"full.jsonl\"`\n- **`id.CheckpointID.Path()`** - Returns sharded path: `<id[:2]>/<id[2:]>`\n- **`SessionMetadataPath(cpID)`** - Returns: `<id[:2]>/<id[2:]>/0/metadata.json`\n- **`SessionFilePath(cpID, fileName)`** - Returns: `<id[:2]>/<id[2:]>/0/<fileName>`\n\n### 7. **Checkpoint Validation Helper**\n**File:** `testenv.go` (lines 1449-1624)\n\n**`env.ValidateCheckpoint(CheckpointValidation)`** provides comprehensive validation:\n- Validates CheckpointSummary (root metadata.json)\n- Validates CommittedMetadata (session-level metadata.json)\n- Validates transcript is valid JSONL\n- Validates content hash matches SHA256 of transcript\n- Validates prompt.txt contains expected content\n\n---\n\n## Summary of Test Patterns\n\n### For Attribution Regression Tests:\n1. Use **integration tests** (`attribution_test.go`) for full end-to-end flows\n2. Use **unit tests** (`manual_commit_test.go`) for specific CondenseSession scenarios\n3. **Key flow:**\n   - Create session → WriteTranscript → SaveStep (shadow branch) → User edits → Commit with hooks → Verify metadata\n\n### For Post-Commit Condensation Tests:\n1. Use **`GitCommitWithShadowHooks()`** to simulate the full commit with hook execution\n2. This automatically:\n   - Runs prepare-commit-msg hook (adds trailers)\n   - Creates commit\n   - Runs post-commit hook (triggers condensation if trailer present)\n3. Verify results by reading from `trace/checkpoints/v1` branch metadata\n\n### Critical Files to Understand:\n- `/repo/cli/cmd/trace/cli/integration_test/testenv.go` - Environment setup\n- `/repo/cli/cmd/trace/cli/integration_test/hooks.go` - Session & hook simulation\n- `/repo/cli/cmd/trace/cli/integration_test/attribution_test.go` - Full integration tests\n- `/repo/cli/cmd/trace/cli/strategy/manual_commit_test.go` - Unit tests for condensation"}],"totalDurationMs":63688,"totalTokens":74070,"totalToolUseCount":21,"usage":{"input_tokens":3,"cache_creation_input_tokens":7060,"cache_read_input_tokens":63444,"output_tokens":3563,"server_tool_use":{"web_search_requests":0,"web_fetch_requests":0},"service_tier":"standard","cache_creation":{"ephemeral_1h_input_tokens":0,"ephemeral_5m_input_tokens":7060},"inference_geo":"","iterations":[],"speed":"standard"}},"sourceToolAssistantUUID":"cb51e1a6-332b-4def-a309-1053bbe1b877","userType":"external","entrypoint":"cli","cwd":"/repo/cli","sessionId":"466e2cb2-1cca-4296-8efd-ef4bb139d9c3","version":"2.1.85","gitBranch":"main","slug":"gentle-wishing-ladybug"}

Main flow with mixed agent/user edits\n2. **`TestManualCommit_AttributionDeletionOnly`** (lines 213-353) - Tests deletion-only commits\n   - Expects `AgentLines=0`, `HumanAdded=0`, `TotalCommitted=0`, `AgentPercentage=0`\n3. **`TestManualCommit_AttributionNoDoubleCount`** (lines 364-517) -

Now I have all the information needed. Let me create a comprehensive summary report.\n\n## Comprehensive Test Infrastructure Summary\n\nI've thoroughly analyzed the existing test patterns for attribution and post-commit condensation in the codebase. Here's the complete infrastructure breakdown:\n\n### 1. **Test Environment Setup** \n**File:** `/repo/cli/cmd/entire/cli/integration_test/testenv.go`\n\n#### Key Structures:\n- **`TestEnv`** - Main test environment struct that manages:\n  - `RepoDir` - Isolated git repository for testing\n  - `ClaudeProjectDir`, `GeminiProjectDir`, `OpenCodeProjectDir` - Agent project directories\n  - `SessionCounter` - Tracks session creation for unique IDs\n\n#### Factory Functions:\n- **`NewTestEnv(t)`** - Creates basic isolated environment without git initialization\n- **`NewRepoEnv(t)`** - Creates repo with git initialized and Entire configured\n- **`NewRepoWithCommit(t)`** - Adds initial commit with `.gitignore` and `README.md`\n- **`NewFeatureBranchEnv(t)`** - Most common setup for session tests; creates feature branch (since Entire skips main/master)\n\n#### Critical Git & Staging Operations:\n- **`GitCommitWithShadowHooks(message, files...)`** - **THE MAIN WORKHORSE** for testing\n  - Stages files, runs `prepare-commit-msg` hook with `ENTIRE_TEST_TTY=1` (simulates human)\n  - Modifies commit message with trailers\n  - Creates commit with go-git\n  - Runs `post-commit` hook (triggers condensation if Entire-Checkpoint trailer present)\n  - This is what tests use instead of raw `git commit`\n\n- **`GitCommitWithShadowHooksAsAgent(message, files...)`** - Like above but with `ENTIRE_TEST_TTY=0` (simulates agent subprocess)\n\n### 2. **Session and Transcript Simulation**\n**File:** `/repo/cli/cmd/entire/cli/integration_test/hooks.go`\n\n#### Session Structure:\n```go\ntype Session struct {\n    ID                string                  // e.g., \"test-session-1\"\n    TranscriptPath    string                  // .entire/tmp/test-session-1.jsonl\n    TranscriptBuilder *TranscriptBuilder      // Helper for building transcript JSON\n    env               *TestEnv                // Reference back to test env\n}\n```\n\n#### Session Creation & Lifecycle:\n- **`env.NewSession()`** - Creates new session with auto-incrementing ID\n  - Generates path: `.entire/tmp/test-session-N.jsonl`\n  - Returns Session struct with TranscriptBuilder ready\n\n- **`session.CreateTranscript(prompt, changes []FileChange)`** - Writes JSONL transcript\n  - Takes a user prompt and array of FileChange{Path, Content}\n  - Adds user message, assistant response, tool uses (mcp__acp__Write), tool results\n  - Writes to session's TranscriptPath\n\n#### Hook Simulation (via HookRunner):\n- **`env.SimulateUserPromptSubmit(sessionID)`** - Simulates Claude Code user-prompt-submit hook\n  - Triggers attribution calculation at prompt start\n  - Captures pre-prompt state (untracked files)\n  \n- **`env.SimulateStop(sessionID, transcriptPath)`** - Simulates stop hook\n  - Called after SaveStep to complete checkpoint\n  - Reads from transcriptPath to determine what was saved\n\n### 3. **Attribution Tests in Integration Tests**\n**File:** `/repo/cli/cmd/entire/cli/integration_test/attribution_test.go`\n\n#### Test Pattern: `TestManualCommit_Attribution` (lines 24-211)\nThis is the **complete integration test** for the full attribution flow:\n\n```\n1. env.InitRepo() → Initialize git repo\n2. env.WriteFile(\"main.go\", content) + env.GitAdd() + env.GitCommit() → Initial commit\n3. env.InitEntire() → Initialize .entire directory\n\n[CHECKPOINT 1 - Agent Work]\n4. session = env.NewSession() → Create session\n5. env.SimulateUserPromptSubmit(session.ID) → Attribution calculation hook\n6. env.WriteFile(\"main.go\", agentContent) → Agent adds function\n7. session.CreateTranscript(prompt, fileChanges) → Write transcript\n8. env.SimulateStop(session.ID, session.TranscriptPath) → Complete checkpoint\n\n[USER EDITS between checkpoints]\n9. env.WriteFile(\"main.go\", userContent) → User adds 5 lines of comments\n\n[CHECKPOINT 2 - New Prompt]\n10. env.SimulateUserPromptSubmit(session.ID) → Attribution calculated again\n11. env.WriteFile(\"main.go\", checkpoint2Content) → Agent adds more code\n12. session.CreateTranscript(prompt2, fileChanges2) → New transcript\n13. env.SimulateStop(session.ID, session.TranscriptPath) → Complete checkpoint 2\n\n[USER COMMITS - Triggers Condensation]\n14. env.GitCommitWithShadowHooks(\"Add functions\", \"main.go\") → CRITICAL: runs hooks\n15. repo.CommitObject(headHash) → Get commit\n16. trailers.ParseCheckpoint(message) → Extract checkpoint ID from trailer\n\n[VERIFY ATTRIBUTION]\n17. repo.Reference(paths.MetadataBranchName) → Get entire/checkpoints/v1 branch\n18. tree.File(SessionMetadataPath(checkpointID)) → Read 0/metadata.json\n19. Unmarshal into checkpoint.CommittedMetadata → Parse JSON\n20. Assert metadata.InitialAttribution fields are correct\n```\n\n#### Key Assertions Pattern:\n```go\nattr := metadata.InitialAttribution\n// Expected: agent=13 lines, human=5 lines, total=18\nif attr.HumanAdded != 5 {\n    t.Errorf(\"HumanAdded = %d, want 5\", attr.HumanAdded)\n}\nif attr.AgentPercentage <= 0 || attr.AgentPercentage >= 100 {\n    t.Errorf(\"AgentPercentage = %.1f%%, should be between 0 and 100\", attr.AgentPercentage)\n}\n```\n\n#### Test Variants:\n1. **`TestManualCommit_Attribution`** (lines 24-211) - Main flow with mixed agent/user edits\n2. **`TestManualCommit_AttributionDeletionOnly`** (lines 213-353) - Tests deletion-only commits\n   - Expects `AgentLines=0`, `HumanAdded=0`, `TotalCommitted=0`, `AgentPercentage=0`\n3. **`TestManualCommit_AttributionNoDoubleCount`** (lines 364-517) - **REGRESSION TEST**\n   - **Bug scenario:** PromptAttributions not cleared after condensation\n   - First cycle: agent 4 lines, user 2 lines → commit\n   - Second cycle: agent 3 lines, user 1 line → expect 1, not 3 (would be double-counted)\n   - **Critical assertion:** `if attr2.HumanAdded != 1 { t.Error(\"should NOT double-count\") }`\n\n#### Helper Functions:\n- **`getAttributionFromMetadata(t, repo, checkpointID)`** - Reads metadata.json from sessions branch\n- **`SessionMetadataPath(checkpointID)`** - Returns path to session-level metadata\n- **`CheckpointSummaryPath(checkpointID)`** - Returns path to root metadata\n\n### 4. **Unit Tests for Condensation (CondenseSession)**\n**File:** `/repo/cli/cmd/entire/cli/strategy/manual_commit_test.go`\n\n#### Key Condensation Tests:\n1. **`TestCondenseSession_IncludesInitialAttribution`** (lines 1971-2156)\n   - Sets up git repo manually using go-git\n   - Creates initial commit\n   - Calls `s.SaveStep()` to create shadow branch\n   - User edits file\n   - Calls `s.CondenseSession(repo, checkpointID, state, nil)`\n   - Verifies `result.CheckpointID` equals input ID\n   - Reads metadata from `entire/checkpoints/v1` branch\n   - Verifies `metadata.InitialAttribution` is populated\n\n2. **`TestCondenseSession_AttributionWithoutShadowBranch`** (lines 2159+)\n   - Tests mid-turn commit (agent commits before SaveStep)\n   - No shadow branch exists\n   - Verifies attribution still calculated using HEAD as base\n\n3. **`TestCondenseSession_AttributionWithoutShadowBranch_MixedHumanAgent`** (lines 2309+)\n   - Similar but with more complex mixed edits\n\n#### Unit Test Pattern:\n```go\ndir := t.TempDir()\nrepo, _ := git.PlainInit(dir, false)\nworktree, _ := repo.Worktree()\n\n// Create initial commit\nos.WriteFile(filepath.Join(dir, \"file.go\"), content, 0o644)\nworktree.Add(\"file.go\")\nworktree.Commit(\"Initial\", &git.CommitOptions{...})\n\nt.Chdir(dir)\ns := &ManualCommitStrategy{}\n\n// Create metadata dir with transcript\nmetadataDir := \".entire/metadata/\" + sessionID\nos.MkdirAll(metadataDir, 0o755)\nos.WriteFile(filepath.Join(metadataDir, \"transcript.jsonl\"), transcript, 0o644)\n\n// Simulate SaveStep → creates shadow branch\ns.SaveStep(context.Background(), StepContext{...})\n\n// User edits\nos.WriteFile(testFile, humanEditedContent, 0o644)\nworktree.Add(\"test.go\")\nworktree.Commit(\"User commit\", &git.CommitOptions{...})\n\n// Load session state\nstate, _ := s.loadSessionState(context.Background(), sessionID)\n\n// Condense\ncheckpointID := id.MustCheckpointID(\"a1b2c3d4e5f6\")\nresult, _ := s.CondenseSession(context.Background(), repo, checkpointID, state, nil)\n\n// Verify\nsessionsRef, _ := repo.Reference(plumbing.NewBranchReferenceName(paths.MetadataBranchName), true)\nsessionsCommit, _ := repo.CommitObject(sessionsRef.Hash())\ntree, _ := sessionsCommit.Tree()\nmetadataFile, _ := tree.File(checkpointID.Path() + \"/0/\" + paths.MetadataFileName)\ncontent, _ := metadataFile.Contents()\njson.Unmarshal([]byte(content), &metadata)\n\n// Assert attribution fields\n```\n\n### 5. **Attribution Data Structures**\n**Location:** `cmd/entire/cli/checkpoint/committed.go`\n\n#### CommittedMetadata (session-level metadata):\n```go\ntype CommittedMetadata struct {\n    InitialAttribution *InitialAttribution `json:\"initial_attribution\"`\n    // ... other fields\n}\n\ntype InitialAttribution struct {\n    AgentLines      int     `json:\"agent_lines\"`\n    HumanAdded      int     `json:\"human_added\"`\n    HumanModified   int     `json:\"human_modified\"`\n    HumanRemoved    int     `json:\"human_removed\"`\n    TotalCommitted  int     `json:\"total_committed\"`\n    AgentPercentage float64 `json:\"agent_percentage\"`\n}\n```\n\n### 6. **Key Test Utilities & Paths**\n- **`paths.MetadataBranchName`** = `\"entire/checkpoints/v1\"`\n- **`paths.MetadataFileName`** = `\"metadata.json\"`\n- **`paths.TranscriptFileName`** = `\"full.jsonl\"`\n- **`id.CheckpointID.Path()`** - Returns sharded path: `<id[:2]>/<id[2:]>`\n- **`SessionMetadataPath(cpID)`** - Returns: `<id[:2]>/<id[2:]>/0/metadata.json`\n- **`SessionFilePath(cpID, fileName)`** - Returns: `<id[:2]>/<id[2:]>/0/<fileName>`\n\n### 7. **Checkpoint Validation Helper**\n**File:** `testenv.go` (lines 1449-1624)\n\n**`env.ValidateCheckpoint(CheckpointValidation)`** provides comprehensive validation:\n- Validates CheckpointSummary (root metadata.json)\n- Validates CommittedMetadata (session-level metadata.json)\n- Validates transcript is valid JSONL\n- Validates content hash matches SHA256 of transcript\n- Validates prompt.txt contains expected content\n\n---\n\n## Summary of Test Patterns\n\n### For Attribution Regression Tests:\n1. Use **integration tests** (`attribution_test.go`) for full end-to-end flows\n2. Use **unit tests** (`manual_commit_test.go`) for specific CondenseSession scenarios\n3. **Key flow:**\n   - Create session → WriteTranscript → SaveStep (shadow branch) → User edits → Commit with hooks → Verify metadata\n\n### For Post-Commit Condensation Tests:\n1. Use **`GitCommitWithShadowHooks()`** to simulate the full commit with hook execution\n2. This automatically:\n   - Runs prepare-commit-msg hook (adds trailers)\n   - Creates commit\n   - Runs post-commit hook (triggers condensation if trailer present)\n3.

This caused `AttributionBaseCommit` to drift behind, making subsequent condensations diff against a stale base and inflate `human_added` with lines from unrelated prior commits.\n\n- **Fix**: Two one-line additions — `state.AttributionBaseCommit = newHead` alongside the existing `state.BaseCommit = newHead` in both functions (`manual_commit_hooks.go` lines ~1146 and ~1187).\n\n- **Test**: `TestManualCommit_AttributionStaleBase` — reproduces the exact production pattern: agent works → commit → unrelated commit while ACTIVE → agent works again → second commit shows inflated attribution.

Core Agent Implementation (`cmd/trace/cli/agent/opencode/`)\n\nThis directory contains 11 files implementing the OpenCode agent integration:\n\n---\n\n#### `/Users/private/trace/cli/cmd/trace/cli/agent/opencode/opencode.go` (278 lines)\n**Purpose:** Main agent implementation - identity, detection, transcript reading, chunking, session operations, and resume command formatting.\n\n**References to `trace` executable/binary:**\n- Line 266: `return \"opencode\"` (in `FormatResumeCommand` for empty session ID)\n- Line 268: `return \"opencode -s \" + sessionID` (in `FormatResumeCommand`)\n\n---\n\n#### `/Users/private/trace/cli/cmd/trace/cli/agent/opencode/types.go` (126 lines)\n**Purpose:** Data types for OpenCode's JSON structures -- session info payloads from the plugin, export JSON types (`ExportSession`, `ExportMessage`, `MessageInfo`, `Part`, `ToolState`, etc.), and file modification tool constants.\n\n**No references to `trace` executable.**\n\n---\n\n#### `/Users/private/trace/cli/cmd/trace/cli/agent/opencode/lifecycle.go` (206 lines)\n**Purpose:** Lifecycle event parsing (session-start, session-end, turn-start, turn-end, compaction hooks), transcript preparation via `opencode export`, and session transcript path management.\n\n**References to `trace` executable/binary:**\n- Line 18 (comment): `Hook name constants -- these become CLI subcommands under 'trace hooks opencode'.`\n\n---\n\n#### `/Users/private/trace/cli/cmd/trace/cli/agent/opencode/hooks.go` (133 lines)\n**Purpose:** Hook installation/uninstallation -- writes `.opencode/plugins/trace.ts` plugin file, checks if hooks are installed, returns supported lifecycle event types.\n\n**References to `trace` executable/binary:**\n- Line 25: `traceMarker = \"Auto-generated by \\`trace enable --agent opencode\\`\"` (marker string)\n- Line 65: `cmdPrefix = .trace\"` (production command prefix injected into plugin template)\n- Line 63: `cmdPrefix = \"go run ${OPENCODE_PROJECT_DIR}/cmd/trace/main.go\"` (local dev command prefix)\n\n---\n\n#### `/Users/private/trace/cli/cmd/trace/cli/agent/opencode/plugin.go` (9 lines)\n**Purpose:** Embeds the TypeScript plugin template (`trace_plugin.ts`) via `//go:embed` and defines the placeholder constant `__TRACE_CMD__`.\n\n**References to `trace` executable/binary:**\n- Line 9: `const traceCmdPlaceholder = \"__TRACE_CMD__\"` (placeholder replaced with `trace` or `go run ...` at install time)\n\n---\n\n#### `/Users/private/trace/cli/cmd/trace/cli/agent/opencode/cli_commands.go` (76 lines)\n**Purpose:** Wrappers for executing `opencode` CLI commands: `opencode export \u003csessionID\u003e`, `opencode session delete \u003csessionID\u003e`, `opencode import \u003cfile\u003e`.\n\n**No references to `trace` executable.** All references are to the `opencode` binary itself (lines 21, 45, 67).\n\n---\n\n#### `/Users/private/trace/cli/cmd/trace/cli/agent/opencode/transcript.go` (260 lines)\n**Purpose:** Transcript analysis -- parsing export JSON, slicing by message index, extracting modified files from tool calls, extracting user prompts, calculating token usage.\n\n**No references to `trace` executable.**\n\n---\n\n#### `/Users/private/trace/cli/cmd/trace/cli/agent/opencode/trace_plugin.ts` (158 lines)\n**Purpose:** The TypeScript plugin template that gets installed to `.opencode/plugins/trace.ts`. It hooks into OpenCode events and calls back to the `trace` CLI.\n\n**References to `trace` executable/binary:**\n- Line 2: `// Auto-generated by \\`trace enable --agent opencode\\``\n- Line 8: `const TRACE_CMD = \"__TRACE_CMD__\"` (placeholder, replaced with `.trace\"` at install time)\n- Line 25: `` await $`echo ${json} | ${TRACE_CMD} hooks opencode ${hookName}`.quiet().nothrow() ``\n- Line 40: `` Bun.spawnSync([\"sh\", \"-c\", `${TRACE_CMD} hooks opencode ${hookName}`], ... ``\n\n---\n\n#### `/Users/private/trace/cli/cmd/trace/cli/agent/opencode/lifecycle_test.go` (360 lines)\n**Purpose:** Unit tests for lifecycle event parsing, resume command formatting, hook names, transcript preparation, and input validation.\n\n**References to `trace` executable/binary:**\n- Line 207: `expected := \"opencode -s sess-abc123\"` (tests `FormatResumeCommand`)\n- Line 219: `if cmd != \"opencode\" {`\n\n---\n\n#### `/Users/private/trace/cli/cmd/trace/cli/agent/opencode/hooks_test.go` (178 lines)\n**Purpose:** Unit tests for hook installation, idempotency, local dev mode, force reinstall, uninstall, and hooks-installed detection.\n\n**References to `trace` executable/binary:**\n- Line 40: `` if !strings.Contains(content, `const TRACE_CMD = .trace\"`) { ``\n- Line 43: `if !strings.Contains(content, \"hooks opencode\") {`\n\n---\n\n#### `/Users/private/trace/cli/cmd/trace/cli/agent/opencode/transcript_test.go` (673 lines)\n**Purpose:** Unit tests for export JSON parsing, transcript position, modified file extraction, token usage calculation, REDACTED round-tripping, and camelCase/apply_patch tool support.\n\n**No references to `trace` executable.**\n\n---\n\n### 2. E2E Test File\n\n#### `/Users/private/trace/cli/e2e/agents/opencode.go` (162 lines)\n**Purpose:** E2E test agent implementation for running OpenCode in test environments. Defines `openCodeAgent` with model selection, warmup/bootstrap, prompt execution via `opencode run`, and tmux-based interactive session support.\n\n**References to `trace` executable/binary:**\n- Line 34: `func (a *openCodeAgent) TraceAgent() string { return \"opencode\" }` (returns the `--agent` name for `trace enable`)\n\n---\n\n### 3. Installed Plugin File (in repo)\n\n#### `/Users/private/trace/cli/.opencode/plugins/trace.ts` (158 lines)\n**Purpose:** The installed (non-template) version of the Trace plugin for this repo's own OpenCode usage. Identical structure to the template but with `__TRACE_CMD__` replaced by `.trace\"`.\n\n**References to `trace` executable/binary:**\n- Line 8: `const TRACE_CMD = .trace\"`\n- Line 25: `` await $`echo ${json} | ${TRACE_CMD} hooks opencode ${hookName}`.quiet().nothrow() ``\n- Line 40: `` Bun.spawnSync([\"sh\", \"-c\", `${TRACE_CMD} hooks opencode ${hookName}`], ... ``\n\n---\n\n### 4. Integration Test Files\n\n#### `/Users/private/trace/cli/cmd/trace/cli/integration_test/opencode_hooks_test.go` (413 lines)\n**Purpose:** Integration tests for the full OpenCode hook flow: session lifecycle, agent-strategy composition, rewind, multi-turn condensation, mid-turn commits, and resumed sessions after commit.\n\n**References to `trace` executable/binary:**\n- Not directly. Tests call the `trace` binary indirectly via `getTestBinary()` in the hook runner.\n\n---\n\n#### `/Users/private/trace/cli/cmd/trace/cli/integration_test/hooks.go` (lines 1158-1442)\n**Purpose:** `OpenCodeHookRunner` and `OpenCodeSession` types that simulate OpenCode hooks for integration tests. Provides methods like `SimulateOpenCodeSessionStart`, `SimulateOpenCodeTurnStart`, `SimulateOpenCodeTurnEnd`, `SimulateOpenCodeSessionEnd`, and `CreateOpenCodeTranscript`.\n\n**References to `trace` executable/binary:**\n- Line 1197: `cmd := exec.Command(getTestBinary(), \"hooks\", \"opencode\", hookName)` (executes `trace hooks opencode \u003chook-name\u003e`)\n\n---\n\n#### `/Users/private/trace/cli/cmd/trace/cli/integration_test/agent_test.go` (lines 1168-1439)\n**Purpose:** Integration tests for OpenCode agent detection (`.opencode` dir, `opencode.json`), hook installation (plugin file creation, idempotency), session operations (ReadSession, WriteSession), and helper methods (FormatResumeCommand, ProtectedDirs, IsPreview).\n\n**References to `trace` executable/binary:**\n- Line 1408: `if cmd != \"opencode -s abc123\" {` (tests FormatResumeCommand)\n- Line 1409: `t.Errorf(\"FormatResumeCommand() = %q, want %q\", cmd, \"opencode -s abc123\")`\n\n---\n\n### 5.

The only file that needs to change is `.opencode/plugins/trace.ts` — this is the repo's own installed plugin file. It currently uses `.trace\"` but since this is the CLI project itself, it should use `go run ${project_dir}/cmd/trace/main.go` to run the locally-built version.\n\nThe `hooks.go` file already has the `localDev` path correctly set to `go run ${OPENCODE_PROJECT_DIR}/cmd/trace/main.go`. However, the OpenCode plugin uses `$` (Bun's shell) and `Bun.spawnSync` which have different variable expansion. Let me check what `OPENCODE_PROJECT_DIR` is — it's likely an environment variable that OpenCode sets to the project directory.\n\nActually, looking more carefully at the async `callHook` function, it uses Bun's `$` template literal shell which would expand `${TRACE_CMD}` as a JS variable (not a shell variable). And in the sync `callHookSync`, the command is passed as a string to `sh -c`. So the `TRACE_CMD` constant holds the full command string.\n\nFor `localDev` mode, the value `go run ${OPENCODE_PROJECT_DIR}/cmd/trace/main.go` gets substituted. But `${OPENCODE_PROJECT_DIR}` would need to be a shell environment variable. Let me check if this is actually set by OpenCode or if there's a different mechanism.\n\nLooking at the template more carefully: the `$` template literal in Bun's shell would interpolate `${TRACE_CMD}` as a JS variable (the const), but `${OPENCODE_PROJECT_DIR}` would need to be expanded by the shell. In the async path `$\\`echo ${json} | ${TRACE_CMD} hooks opencode ${hookName}\\``, Bun's `$` substitutes JS variables. So `TRACE_CMD` would be the literal string `go run ${OPENCODE_PROJECT_DIR}/cmd/trace/main.go` — but then `${OPENCODE_PROJECT_DIR}` wouldn't be expanded because it's inside Bun's shell, not a regular shell.\n\nThe sync path does `sh -c` with string interpolation, so `TRACE_CMD` becomes `go run ${OPENCODE_PROJECT_DIR}/cmd/trace/main.go` and then `sh -c` would expand `${OPENCODE_PROJECT_DIR}`.\n\nBut the async path would have an issue. The plugin already has access to `directory` (the project directory), so the best approach for local dev would be to use `directory` instead of an env var.\n\nLet me look at what the current approach actually does more carefully. The `.opencode/plugins/trace.ts` file just needs to be regenerated with `localDev=true`. Let me just update the installed plugin file to use the local dev command. The simplest and most correct approach is to use `go run` with the `directory` variable that's already available in the plugin scope:","type":"text"},{"id":"toolu_013gd2XnAwzs5PDqSuWD3EQN","input":{"filePath":"/Users/private/trace/cli/.opencode/plugins/trace.ts","oldString":"  const TRACE_CMD = .trace\"","newString":"  const TRACE_CMD = `go run ${directory}/cmd/trace/main.go`"},"name":"edit","result":{"output":"Edit applied successfully.","status":"success"},"type":"tool_use"}]}

If I replace it with `` `go run ${directory}/cmd/trace/main.go` ``, the template substitution would produce `const TRACE_CMD = \"` followed by the template literal, which would break the JS syntax.\n\nLet me look at how the template substitution works. The template has `\"__TRACE_CMD__\"` (with quotes), and `strings.ReplaceAll` replaces `__TRACE_CMD__` with the command prefix. So:\n\n- Production: `const TRACE_CMD = .trace\"` \n- Local dev: `const TRACE_CMD = \"go run ${OPENCODE_PROJECT_DIR}/cmd/trace/main.go\"` — this would mean `${OPENCODE_PROJECT_DIR}` is a literal string inside JS quotes, which wouldn't be expanded.\n\nActually for the async path with Bun's `$`, `${TRACE_CMD}` would be the JS variable value (the literal string including `${OPENCODE_PROJECT_DIR}`), and Bun's shell doesn't expand environment variables in the same way. Let me reconsider.\n\nFor the installed plugin (what we're editing), we need a different approach. The plugin has access to `directory` as a JS variable. Instead of hardcoding the command in a string constant, I should make it use a template literal.\n\nBut the template mechanism replaces `__TRACE_CMD__` inside double quotes. For local dev, we need a template literal (backticks) instead of a quoted string to interpolate `directory`. Let me update the approach — change the template itself to use a different pattern for local dev:\n\nActually, the cleanest fix is simpler. The `.opencode/plugins/trace.ts` file is the *installed* file in this specific repo. It's not the template. I can edit it directly to whatever works. The template and `hooks.go` generate this file, but for the repo's own use, this file is what matters.\n\nLet me verify the current state of my edit is syntactically correct:","type":"text"},{"id":"toolu_01Toj6zsCcZdoJHgV9EWuaNU","input":{"filePath":"/Users/private/trace/cli/.opencode/plugins/trace.ts","offset":1,"limit":10},"name":"read","result":{"output":"\u003cpath\u003e/Users/private/trace/cli/.opencode/plugins/trace.ts\u003c/path\u003e\n\u003ctype\u003efile\u003c/type\u003e\n\u003ccontent\u003e1: // Trace CLI plugin for OpenCode\n2: // Auto-generated by `trace enable --agent opencode`\n3: // Do not edit manually — changes will be overwritten on next install.\n4: // Requires Bun runtime (used by OpenCode's plugin system for loading ESM plugins).\n5: import type { Plugin } from \"@opencode-ai/plugin\"\n6: \n7: export const TracePlugin: Plugin = async ({ $, directory }) =\u003e {\n8:   const TRACE_CMD = `go run ${directory}/cmd/trace/main.go`\n9:   // Track seen user messages to fire turn-start only once per message\n10:   const seenUserMessages = new Set\u003cstring\u003e()\n\n(Showing lines 1-10 of 158.

That uses a JS template literal with the `directory` variable that OpenCode passes to the plugin function. This will correctly resolve to the project directory at runtime.\n\nNow I need to also update the `hooks.go` local dev path to use the same `directory`-based approach, and update the template mechanism so that `trace enable --agent opencode` with `localDev=true` produces the correct output.\n\nThe challenge is that the template uses simple string replacement of `__TRACE_CMD__` inside a double-quoted JS string. For local dev, we need a template literal (backticks) instead. Let me update the approach:\n\n1. In `hooks.go`, for `localDev`, replace the trace `const TRACE_CMD = \"__TRACE_CMD__\"` line instead of just the placeholder.\n2. Or better: change the placeholder replacement to also handle the surrounding quotes.\n\nLet me look at the template again to decide the best approach:\n\nThe template has: `const TRACE_CMD = \"__TRACE_CMD__\"`\n\nFor production, replacing `__TRACE_CMD__` with `trace` gives: `const TRACE_CMD = .trace\"` — correct JS.\n\nFor local dev, we need: `` const TRACE_CMD = `go run ${directory}/cmd/trace/main.go` `` — which requires backticks, not double quotes.\n\nThe simplest approach: change `hooks.go` to do a broader replacement that includes the quotes when in `localDev` mode.","type":"text"},{"id":"toolu_01LYZY7vTeD2Eo2NcvypuBeA","input":{"filePath":"/Users/private/trace/cli/cmd/trace/cli/agent/opencode/hooks.go","oldString":"\t// Build the command prefix\n\tvar cmdPrefix string\n\tif localDev {\n\t\tcmdPrefix = \"go run ${OPENCODE_PROJECT_DIR}/cmd/trace/main.go\"\n\t} else {\n\t\tcmdPrefix = .trace\"\n\t}\n\n\t// Generate plugin content from template\n\tcontent := strings.ReplaceAll(pluginTemplate, traceCmdPlaceholder, cmdPrefix)","newString":"\t// Generate plugin content from template.\n\t// In local-dev mode the command uses the `directory` variable that OpenCode\n\t// passes to the plugin, so the JS constant must be a template literal (backticks)\n\t// rather than a double-quoted string.\n\tvar content string\n\tif localDev {\n\t\t// Replace the trace quoted placeholder with a template literal.\n\t\tcontent = strings.ReplaceAll(\n\t\t\tpluginTemplate,\n\t\t\t`\"`+traceCmdPlaceholder+`\"`,\n\t\t\t\"`go run ${directory}/cmd/trace/main.go`\",\n\t\t)\n\t} else {\n\t\tcontent = strings.ReplaceAll(pluginTemplate, traceCmdPlaceholder, .trace\")\n\t}"},"name":"edit","result":{"output":"Edit applied successfully.","status":"success"},"type":"tool_use"}]}

Identical structure to the template but with `__ENTIRE_CMD__` replaced by `\"entire\"`.\n\n**References to `entire` executable/binary:**\n- Line 8: `const ENTIRE_CMD = \"entire\"`\n- Line 25: `` await $`echo ${json} | ${ENTIRE_CMD} hooks opencode ${hookName}`.quiet().nothrow() ``\n- Line 40: `` Bun.spawnSync([\"sh\", \"-c\", `${ENTIRE_CMD} hooks opencode ${hookName}`], ... ``\n\n---\n\n### 4. Integration Test Files\n\n#### `/Users/private/entire/cli/cmd/entire/cli/integration_test/opencode_hooks_test.go` (413 lines)\n**Purpose:** Integration tests for the full OpenCode hook flow: session lifecycle, agent-strategy composition, rewind, multi-turn condensation, mid-turn commits, and resumed sessions after commit.\n\n**References to `entire` executable/binary:**\n- Not directly. Tests call the `entire` binary indirectly via `getTestBinary()` in the hook runner.\n\n---\n\n#### `/Users/private/entire/cli/cmd/entire/cli/integration_test/hooks.go` (lines 1158-1442)\n**Purpose:** `OpenCodeHookRunner` and `OpenCodeSession` types that simulate OpenCode hooks for integration tests. Provides methods like `SimulateOpenCodeSessionStart`, `SimulateOpenCodeTurnStart`, `SimulateOpenCodeTurnEnd`, `SimulateOpenCodeSessionEnd`, and `CreateOpenCodeTranscript`.\n\n**References to `entire` executable/binary:**\n- Line 1197: `cmd := exec.Command(getTestBinary(), \"hooks\", \"opencode\", hookName)` (executes `entire hooks opencode \u003chook-name\u003e`)\n\n---\n\n#### `/Users/private/entire/cli/cmd/entire/cli/integration_test/agent_test.go` (lines 1168-1439)\n**Purpose:** Integration tests for OpenCode agent detection (`.opencode` dir, `opencode.json`), hook installation (plugin file creation, idempotency), session operations (ReadSession, WriteSession), and helper methods (FormatResumeCommand, ProtectedDirs, IsPreview).\n\n**References to `entire` executable/binary:**\n- Line 1408: `if cmd != \"opencode -s abc123\" {` (tests FormatResumeCommand)\n- Line 1409: `t.Errorf(\"FormatResumeCommand() = %q, want %q\", cmd, \"opencode -s abc123\")`\n\n---\n\n### 5. E2E Test Utilities\n\n#### `/Users/private/entire/cli/e2e/testutil/repo.go` (lines 103-113)\n**Purpose:** OpenCode-specific E2E test repo setup -- writes `opencode.json` with permission config and optional API key.\n\n**No references to `entire` executable.**\n\n---\n\n### 6.

The only file that needs to change is `.opencode/plugins/entire.ts` — this is the repo's own installed plugin file. It currently uses `\"entire\"` but since this is the CLI project itself, it should use `go run ${project_dir}/cmd/entire/main.go` to run the locally-built version.\n\nThe `hooks.go` file already has the `localDev` path correctly set to `go run ${OPENCODE_PROJECT_DIR}/cmd/entire/main.go`. However, the OpenCode plugin uses `$` (Bun's shell) and `Bun.spawnSync` which have different variable expansion. Let me check what `OPENCODE_PROJECT_DIR` is — it's likely an environment variable that OpenCode sets to the project directory.\n\nActually, looking more carefully at the async `callHook` function, it uses Bun's `$` template literal shell which would expand `${ENTIRE_CMD}` as a JS variable (not a shell variable). And in the sync `callHookSync`, the command is passed as a string to `sh -c`. So the `ENTIRE_CMD` constant holds the full command string.\n\nFor `localDev` mode, the value `go run ${OPENCODE_PROJECT_DIR}/cmd/entire/main.go` gets substituted. But `${OPENCODE_PROJECT_DIR}` would need to be a shell environment variable. Let me check if this is actually set by OpenCode or if there's a different mechanism.\n\nLooking at the template more carefully: the `$` template literal in Bun's shell would interpolate `${ENTIRE_CMD}` as a JS variable (the const), but `${OPENCODE_PROJECT_DIR}` would need to be expanded by the shell. In the async path `$\\`echo ${json} | ${ENTIRE_CMD} hooks opencode ${hookName}\\``, Bun's `$` substitutes JS variables. So `ENTIRE_CMD` would be the literal string `go run ${OPENCODE_PROJECT_DIR}/cmd/entire/main.go` — but then `${OPENCODE_PROJECT_DIR}` wouldn't be expanded because it's inside Bun's shell, not a regular shell.\n\nThe sync path does `sh -c` with string interpolation, so `ENTIRE_CMD` becomes `go run ${OPENCODE_PROJECT_DIR}/cmd/entire/main.go` and then `sh -c` would expand `${OPENCODE_PROJECT_DIR}`.\n\nBut the async path would have an issue. The plugin already has access to `directory` (the project directory), so the best approach for local dev would be to use `directory` instead of an env var.\n\nLet me look at what the current approach actually does more carefully. The `.opencode/plugins/entire.ts` file just needs to be regenerated with `localDev=true`. Let me just update the installed plugin file to use the local dev command. The simplest and most correct approach is to use `go run` with the `directory` variable that's already available in the plugin scope:","type":"text"},{"id":"toolu_013gd2XnAwzs5PDqSuWD3EQN","input":{"filePath":"/Users/private/entire/cli/.opencode/plugins/entire.ts","oldString":"  const ENTIRE_CMD = \"entire\"","newString":"  const ENTIRE_CMD = `go run ${directory}/cmd/entire/main.go`"},"name":"edit","result":{"output":"Edit applied successfully.","status":"success"},"type":"tool_use"}]}

If I replace it with `` `go run ${directory}/cmd/entire/main.go` ``, the template substitution would produce `const ENTIRE_CMD = \"` followed by the template literal, which would break the JS syntax.\n\nLet me look at how the template substitution works. The template has `\"__ENTIRE_CMD__\"` (with quotes), and `strings.ReplaceAll` replaces `__ENTIRE_CMD__` with the command prefix. So:\n\n- Production: `const ENTIRE_CMD = \"entire\"` \n- Local dev: `const ENTIRE_CMD = \"go run ${OPENCODE_PROJECT_DIR}/cmd/entire/main.go\"` — this would mean `${OPENCODE_PROJECT_DIR}` is a literal string inside JS quotes, which wouldn't be expanded.\n\nActually for the async path with Bun's `$`, `${ENTIRE_CMD}` would be the JS variable value (the literal string including `${OPENCODE_PROJECT_DIR}`), and Bun's shell doesn't expand environment variables in the same way. Let me reconsider.\n\nFor the installed plugin (what we're editing), we need a different approach. The plugin has access to `directory` as a JS variable. Instead of hardcoding the command in a string constant, I should make it use a template literal.\n\nBut the template mechanism replaces `__ENTIRE_CMD__` inside double quotes. For local dev, we need a template literal (backticks) instead of a quoted string to interpolate `directory`. Let me update the approach — change the template itself to use a different pattern for local dev:\n\nActually, the cleanest fix is simpler. The `.opencode/plugins/entire.ts` file is the *installed* file in this specific repo. It's not the template. I can edit it directly to whatever works. The template and `hooks.go` generate this file, but for the repo's own use, this file is what matters.\n\nLet me verify the current state of my edit is syntactically correct:","type":"text"},{"id":"toolu_01Toj6zsCcZdoJHgV9EWuaNU","input":{"filePath":"/Users/private/entire/cli/.opencode/plugins/entire.ts","offset":1,"limit":10},"name":"read","result":{"output":"\u003cpath\u003e/Users/private/entire/cli/.opencode/plugins/entire.ts\u003c/path\u003e\n\u003ctype\u003efile\u003c/type\u003e\n\u003ccontent\u003e1: // Entire CLI plugin for OpenCode\n2: // Auto-generated by `entire enable --agent opencode`\n3: // Do not edit manually — changes will be overwritten on next install.\n4: // Requires Bun runtime (used by OpenCode's plugin system for loading ESM plugins).\n5: import type { Plugin } from \"@opencode-ai/plugin\"\n6: \n7: export const EntirePlugin: Plugin = async ({ $, directory }) =\u003e {\n8:   const ENTIRE_CMD = `go run ${directory}/cmd/entire/main.go`\n9:   // Track seen user messages to fire turn-start only once per message\n10:   const seenUserMessages = new Set\u003cstring\u003e()\n\n(Showing lines 1-10 of 158.

Core Agent Implementation (`cmd/trace/cli/agent/opencode/`)\n\nThis directory contains 11 files implementing the OpenCode agent integration:\n\n---\n\n#### `/Users/private/trace/cli/cmd/trace/cli/agent/opencode/opencode.go` (278 lines)\n**Purpose:** Main agent implementation - identity, detection, transcript reading, chunking, session operations, and resume command formatting.\n\n**References to `trace` executable/binary:**\n- Line 266: `return \"opencode\"` (in `FormatResumeCommand` for empty session ID)\n- Line 268: `return \"opencode -s \" + sessionID` (in `FormatResumeCommand`)\n\n---\n\n#### `/Users/private/trace/cli/cmd/trace/cli/agent/opencode/types.go` (126 lines)\n**Purpose:** Data types for OpenCode's JSON structures -- session info payloads from the plugin, export JSON types (`ExportSession`, `ExportMessage`, `MessageInfo`, `Part`, `ToolState`, etc.), and file modification tool constants.\n\n**No references to `trace` executable.**\n\n---\n\n#### `/Users/private/trace/cli/cmd/trace/cli/agent/opencode/lifecycle.go` (206 lines)\n**Purpose:** Lifecycle event parsing (session-start, session-end, turn-start, turn-end, compaction hooks), transcript preparation via `opencode export`, and session transcript path management.\n\n**References to `trace` executable/binary:**\n- Line 18 (comment): `Hook name constants -- these become CLI subcommands under 'trace hooks opencode'.`\n\n---\n\n#### `/Users/private/trace/cli/cmd/trace/cli/agent/opencode/hooks.go` (133 lines)\n**Purpose:** Hook installation/uninstallation -- writes `.opencode/plugins/trace.ts` plugin file, checks if hooks are installed, returns supported lifecycle event types.\n\n**References to `trace` executable/binary:**\n- Line 25: `traceMarker = \"Auto-generated by \\`trace enable --agent opencode\\`\"` (marker string)\n- Line 65: `cmdPrefix = .trace\"` (production command prefix injected into plugin template)\n- Line 63: `cmdPrefix = \"go run ${OPENCODE_PROJECT_DIR}/cmd/trace/main.go\"` (local dev command prefix)\n\n---\n\n#### `/Users/private/trace/cli/cmd/trace/cli/agent/opencode/plugin.go` (9 lines)\n**Purpose:** Embeds the TypeScript plugin template (`trace_plugin.ts`) via `//go:embed` and defines the placeholder constant `__TRACE_CMD__`.\n\n**References to `trace` executable/binary:**\n- Line 9: `const traceCmdPlaceholder = \"__TRACE_CMD__\"` (placeholder replaced with `trace` or `go run ...` at install time)\n\n---\n\n#### `/Users/private/trace/cli/cmd/trace/cli/agent/opencode/cli_commands.go` (76 lines)\n**Purpose:** Wrappers for executing `opencode` CLI commands: `opencode export <sessionID>`, `opencode session delete <sessionID>`, `opencode import <file>`.\n\n**No references to `trace` executable.** All references are to the `opencode` binary itself (lines 21, 45, 67).\n\n---\n\n#### `/Users/private/trace/cli/cmd/trace/cli/agent/opencode/transcript.go` (260 lines)\n**Purpose:** Transcript analysis -- parsing export JSON, slicing by message index, extracting modified files from tool calls, extracting user prompts, calculating token usage.\n\n**No references to `trace` executable.**\n\n---\n\n#### `/Users/private/trace/cli/cmd/trace/cli/agent/opencode/trace_plugin.ts` (158 lines)\n**Purpose:** The TypeScript plugin template that gets installed to `.opencode/plugins/trace.ts`. It hooks into OpenCode events and calls back to the `trace` CLI.\n\n**References to `trace` executable/binary:**\n- Line 2: `// Auto-generated by \\`trace enable --agent opencode\\``\n- Line 8: `const TRACE_CMD = \"__TRACE_CMD__\"` (placeholder, replaced with `.trace\"` at install time)\n- Line 25: `` await $`echo ${json} | ${TRACE_CMD} hooks opencode ${hookName}`.quiet().nothrow() ``\n- Line 40: `` Bun.spawnSync([\"sh\", \"-c\", `${TRACE_CMD} hooks opencode ${hookName}`], ... ``\n\n---\n\n#### `/Users/private/trace/cli/cmd/trace/cli/agent/opencode/lifecycle_test.go` (360 lines)\n**Purpose:** Unit tests for lifecycle event parsing, resume command formatting, hook names, transcript preparation, and input validation.\n\n**References to `trace` executable/binary:**\n- Line 207: `expected := \"opencode -s sess-abc123\"` (tests `FormatResumeCommand`)\n- Line 219: `if cmd != \"opencode\" {`\n\n---\n\n#### `/Users/private/trace/cli/cmd/trace/cli/agent/opencode/hooks_test.go` (178 lines)\n**Purpose:** Unit tests for hook installation, idempotency, local dev mode, force reinstall, uninstall, and hooks-installed detection.\n\n**References to `trace` executable/binary:**\n- Line 40: `` if !strings.Contains(content, `const TRACE_CMD = .trace\"`) { ``\n- Line 43: `if !strings.Contains(content, \"hooks opencode\") {`\n\n---\n\n#### `/Users/private/trace/cli/cmd/trace/cli/agent/opencode/transcript_test.go` (673 lines)\n**Purpose:** Unit tests for export JSON parsing, transcript position, modified file extraction, token usage calculation, REDACTED round-tripping, and camelCase/apply_patch tool support.\n\n**No references to `trace` executable.**\n\n---\n\n### 2. E2E Test File\n\n#### `/Users/private/trace/cli/e2e/agents/opencode.go` (162 lines)\n**Purpose:** E2E test agent implementation for running OpenCode in test environments. Defines `openCodeAgent` with model selection, warmup/bootstrap, prompt execution via `opencode run`, and tmux-based interactive session support.\n\n**References to `trace` executable/binary:**\n- Line 34: `func (a *openCodeAgent) TraceAgent() string { return \"opencode\" }` (returns the `--agent` name for `trace enable`)\n\n---\n\n### 3. Installed Plugin File (in repo)\n\n#### `/Users/private/trace/cli/.opencode/plugins/trace.ts` (158 lines)\n**Purpose:** The installed (non-template) version of the Trace plugin for this repo's own OpenCode usage. Identical structure to the template but with `__TRACE_CMD__` replaced by `.trace\"`.\n\n**References to `trace` executable/binary:**\n- Line 8: `const TRACE_CMD = .trace\"`\n- Line 25: `` await $`echo ${json} | ${TRACE_CMD} hooks opencode ${hookName}`.quiet().nothrow() ``\n- Line 40: `` Bun.spawnSync([\"sh\", \"-c\", `${TRACE_CMD} hooks opencode ${hookName}`], ... ``\n\n---\n\n### 4. Integration Test Files\n\n#### `/Users/private/trace/cli/cmd/trace/cli/integration_test/opencode_hooks_test.go` (413 lines)\n**Purpose:** Integration tests for the full OpenCode hook flow: session lifecycle, agent-strategy composition, rewind, multi-turn condensation, mid-turn commits, and resumed sessions after commit.\n\n**References to `trace` executable/binary:**\n- Not directly. Tests call the `trace` binary indirectly via `getTestBinary()` in the hook runner.\n\n---\n\n#### `/Users/private/trace/cli/cmd/trace/cli/integration_test/hooks.go` (lines 1158-1442)\n**Purpose:** `OpenCodeHookRunner` and `OpenCodeSession` types that simulate OpenCode hooks for integration tests.

+//     RequiredRules), but only matches an exact 40-character lowercase body
+//     and is further filtered by entropy<=3.5 and a two-digit minimum. A
+//     high-entropy 40-char sbp_ token captured alone IS caught by
+//     betterleaks; what this layer adds for sbp_ is coverage of bodies at
+//     other lengths, lower entropy, or without two digits.
+//
+// Supabase (https://supabase.com/docs/guides/getting-started/api-keys):
+//   - sb_secret_...      secret API key (replaces the legacy service_role
+//     key; bypasses row-level security, server-side
+//     only) — SENSITIVE, always redacted.
+//   - sbp_...            personal access token used by the Supabase CLI and
+//     Management API — SENSITIVE, always redacted.
+//   - sb_publishable_... publishable key (replaces the legacy anon key). It
+//     is designed to be embedded in client-side code and
+//     is protected by row-level security, so it is NOT a
+//     secret and is intentionally NOT redacted here.
+//     Redacting it would be false-positive noise; this
+//     matches betterleaks, which also ships no
+//     publishable-key rule.
+//
+// The current real key bodies are 31 chars (sb_secret_) and 40 chars
+// (sbp_); charsets mirror betterleaks (sb_secret_ keys are mixed-case
+// base64url, sbp_ tokens are lowercase). The {20,} floor comfortably
+// catches the current and plausibly-longer future formats while rejecting
+// short identifier-like collisions such as "sb_secret_short".
+//
+// Known false-positive class: because the body charset includes `_` and
+// the {20,} length check is open-ended, sufficiently long snake_case
+// identifiers that merely start with a provider prefix are redacted even
+// though they aren't secrets — e.g. `sb_secret_key_rotation_handler`, or
+// mid-word inside a longer identifier like
+// `libsbp_something_long_enough_value`. This is
+// accepted: over-redaction is the safe direction here (see
+// TestString_SupabaseProviderTokenLongIdentifierOverRedaction), and adding
+// anchors or capping the body length to eliminate it would reopen the
+// low-entropy under-redaction gap below.
+//
+// The prefix is deliberately NOT preceded by a \b word boundary. \b requires
+// the character before the prefix to be a non-word char, so a secret glued to
+// a preceding word character — an underscore-joined name (FOO_sb_secret_…) or,
+// in the JSONL fall-back / raw redact.Bytes path, a JSON escape whose trailing
+// letter abuts the prefix (…line1\nsb_secret_…, where the byte before "sb" is
+// the literal 'n') — would slip past. Because these low-entropy secrets are
+// backed up by no other layer, missing them means the raw key reaches the
+// checkpoint blob. Dropping the anchor is redaction-completeness-safe: any
+// high-entropy incidental match would already be caught by the entropy layer,
+// and a mid-word identifier collision (documented above) only ever
+// over-redacts, never under-redacts.

+# to an "entire" binary on PATH. If neither is available it exits 0 so it never
+# blocks the surrounding git or agent operation.
