Summary of cleanups applied based on the three reviewers' findings:\n\n## Fixed\n\n1. **Returned timing from `process_input_with_runtime` instead of stashing it on `Session`** (Agent 2 #1). Dropped `last_input_inference_duration` / `last_input_tool_duration` fields, the `last_input_timing()` getter, and the per-call reset prologue. Signature is now `-> (SessionInputTiming, Result<(), Error>)`. Eliminates the \"must read immediately\" implicit contract.\n\n2. **Replaced the `record_inference_duration!` macro with a free function** `record_elapsed(&mut Option, &mut Duration)` (Agent 1 #2, Agent 2 #2). Same 7 call sites, but type-checked, IDE-discoverable, and no macro hygiene.\n\n3. **Made `run_store` required on `DetachedRunBootstrapGuard::arm()`** (Agent 1 #7, Agent 2 #3/#5). Dropped the `Option` field and the external setter pattern. Drop impl unconditionally builds the conclusion now.\n\n4. **Extracted `emit_workflow_run_failed` helper** (Agent 1 #7, Agent 2 #4). Collapses the four near-identical \"build conclusion → emit run.failed\" sites in `start.rs` (terminal engine failure, both Drop guards, `persist_detached_failure`) into one shared function.\n\n5. **Added `StageTiming::active_only(inference, tool)` constructor** (Agent 1 #1). Removed the local `active_stage_timing` helper in `handler/llm/api.rs` and unified `acp.rs` and `command.rs` on the same shape.\n\n6. **Reverted `Box` in `CodergenResult::Text`** (Agent 1 #6, Agent 2 #6). Was the worst of both worlds — didn't equalise variant size, forced `.map(|usage| *usage)` ceremony at every call site. Used `#[allow(clippy::large_enum_variant, reason = \"...\")]` matching the established pattern in `event/events.rs` and `event/sink.rs`.\n\n7. **Hoisted `test_usage` and `mark_run_running` to `test_support`** (Agent 1 #3/#4). `test_usage` was duplicated in 4 files (this PR was about to add a 5th); the 4th `mark_run_running` copy was right next to a pre-existing 3-event seed in test_support that didn't quite match. Both are now public helpers in `crate::test_support`.\n\n## Skipped (with reason)\n\n- **Make Drop guard tasks survive runtime shutdown** (Agent 3 #3) — flagged as a correctness-on-shutdown concern, not introduced by this PR; widening it would be a separate fix.\n- **`wait_for_conclusion` polling timeout hardening** (Agent 2 #8) — minor CI flake risk; current 50ms budget is enough for unit tests.\n- **`Candidate::timing` zero on LLM-failure heuristic fallback** (Agent 2 #9, Agent 3 implicit) — agent itself noted this is acceptable; capturing wasted inference on errors would require threading Instants through the fan-in evaluator.\n- **Helper for the 3-line failed-outcome decoration in agent.rs/prompt.rs** (Agent 2 #7/#10) — marginal benefit not worth the indirection.\n\n## Verification\n\n- `cargo +nightly-2026-04-14 clippy --workspace --all-targets -- -D warnings` clean\n- `cargo +nightly-2026-04-14 fmt --check --all` clean\n- `cargo nextest run -p fabro-workflow -p fabro-agent -p fabro-types -p fabro-core` — all 3592 tests pass (1175 + 1844 + 573 across the affected crates).", + "thread.implement.current_node": "simplify_opus", + "graph.model_stylesheet": "\n * { model: claude-opus-4-7; }\n ", + "internal.retry_count.simplify_gpt": 0, + "internal.work_dir": "/home/daytona/workspace/fabro", + "outcome": "succeeded", + "response.simplify_gpt": "Reviewed the branch diff vs merge base and ran the parallel review pass.

Verified on `01KSE2PAVXD56N4TWNK4T5H5VA`: 10 stage.completed events and 1 run.failed event all carry `inference_time_ms: 0, tool_time_ms: 0`, even though stages like `implement@1` (94 min wall) and `simplify_opus@1` (29 min wall) were doing nothing but inference and tool calls.\n\nTwo independent bugs:\n\n1. **No production handler ever populates `Outcome.timing`.** The plumbing from `Outcome.timing` → `NodeResult` (`lib/crates/fabro-core/src/executor.rs:30-37`) → `StageTiming` → `stage.completed` props → projection → billing rollup → run.completed/failed → UI is fully wired and shipped as of #343 (2026-05-21), but `AgentHandler::execute`, `PromptHandler::execute`, `CommandHandler::execute`, and `FanInHandler` all build `Outcome::success()` and never touch `.timing`. The executor falls back to zero, and every downstream consumer faithfully aggregates zero.\n\n2. **`persist_terminal_engine_failure` and its sibling Drop-guard failure paths discard timing/billing entirely.** When the engine returns `Err` (e.g. `VisitLimitExceeded`, which is what killed the user's run), `lib/crates/fabro-workflow/src/operations/start.rs:284-308` builds a `Conclusion` via `build_conclusion_from_store`, then throws it away (`let _conclusion = ...`) and emits `WorkflowRunFailed` with `RunTiming::wall_only(...)` and `None` for billing/diff. The three Drop-guard paths (`start.rs:934`, `1001`, `1033`) do similar with `RunTiming::default()` and never even build a conclusion.\n\nGoal: stage and run events carry real per-stage `inference_time_ms` + `tool_time_ms`; engine-failure terminal events preserve the conclusion's rolled-up timing and billing.\n\n## Approach\n\n### Part A — Capture inference + tool time in handlers (Bug 1)\n\n**A1. `fabro-agent` — accumulate per-input timing in `Session`**\n\n`lib/crates/fabro-agent/src/session.rs`\n\nAdd two `Duration` accumulators to `Session` (initialised to `Duration::ZERO`):\n- `last_input_inference_duration`\n- `last_input_tool_duration`\n\nIn `process_input_with_runtime` (line 1196), zero them at entry so each call's totals are independent.\n\nIn `run_single_input` (line 1254):\n- Wrap the inference span: capture `Instant::now()` immediately before opening the stream at line 1391, and add `.elapsed()` to `last_input_inference_duration` once `response = Some(resp)` (line 1487-1490) OR when the loop exits with an error/cancellation. The whole `'streamattempts` loop counts as inference work — retries included.\n- Wrap the tool span around `execute_tool_calls` at line 1705-1719: `Instant::now()` before, accumulate `.elapsed()` after `.await`.\n\nExpose a getter:\n```rust\npub fn last_input_timing(&self) -> SessionInputTiming { ... }\n```\nwhere `SessionInputTiming { pub inference: Duration, pub tool: Duration }` is a new tiny struct in `fabro-agent`.\n\n**A2. `fabro-workflow` — thread timing through the backend boundary**\n\n`lib/crates/fabro-workflow/src/handler/agent.rs`\n\nExtend `CodergenResult::Text` with a `timing: fabro_types::StageTiming` field (wall is irrelevant — see note below). Update the few `CodergenResult::Text { ... }` constructions found by the explore agent to populate it; existing match-bindings only read `text`/`usage`/`files_touched` so they keep compiling with `..` patterns. `CodergenResult::Full(outcome)` keeps current behaviour — the outcome itself already carries any timing.\n\nNote on wall: `lib/crates/fabro-core/src/executor.rs:30-37` reads ONLY `inference_time_ms` and `tool_time_ms` out of `outcome.timing`. The wall comes from the executor's own stopwatch. So we construct `StageTiming::new(0, inference_ms, tool_ms)` and document that the wall field is ignored in this hop.\n\n`lib/crates/fabro-workflow/src/handler/llm/api.rs`\n\n- `AgentApiBackend::run` (line 1103): after `session.process_input_with_runtime(...)` returns, read `session.last_input_timing()` and set the new `timing` on `CodergenResult::Text` at line 1094.\n- `AgentApiBackend::one_shot` (line 994): wrap the `complete_one_shot_request` call at line 1053 with `Instant::now()` / `.elapsed()`. Accumulate across repair iterations of the surrounding loop. All of it counts as inference; no tool work happens in `one_shot`. Set `timing` on `CodergenResult::Text` at line 1094.\n\n`lib/crates/fabro-workflow/src/handler/llm/acp.rs`\n\n`AgentAcpBackend::run` (line ~140): already exposes `result.duration_ms`. Set `timing: StageTiming::new(0, duration_ms, 0)` on the returned `CodergenResult::Text` (per user decision: attribute all ACP duration to inference; ACP is opaque about the split).\n\n**A3. Consume timing in stage handlers and set `outcome.timing`**\n\n- `lib/crates/fabro-workflow/src/handler/agent.rs:341` — after building `outcome`, before the final `Ok(outcome)`, set `outcome.timing = Some(timing_from_codergen_result)`.\n- `lib/crates/fabro-workflow/src/handler/prompt.rs:180` — same pattern.\n- `lib/crates/fabro-workflow/src/handler/fan_in.rs:266` — backend returns timing; pass it onto the outcome built from the fan-in response.\n- `lib/crates/fabro-workflow/src/handler/command.rs:175` — `outcome.timing = Some(StageTiming::new(0, 0, result.duration_ms))`. All command wall-time is tool time. `result.duration_ms` is already at line 154 in scope.\n\nOther handlers (`human`, `wait`, `conditional`, `parallel`, `start`, `exit`, `structured_output`, `manager_loop`) do no inference or tool work. Leave `outcome.timing` as `None`; the executor will naturally produce `inference: 0, tool: 0` for those stages, which is correct.\n\n### Part B — Preserve conclusion timing on engine failure (Bug 2)\n\n`lib/crates/fabro-workflow/src/operations/start.rs`\n\n**B1. Main path** (`persist_terminal_engine_failure`, line 274-308):\n- Rename `_conclusion` → `conclusion` and use it:\n - Pass `conclusion.timing` (already a `RunTiming` with the proper inference/tool/wall rollup from `build_conclusion_from_parts`) instead of `RunTiming::wall_only(...)`.\n - Pass `conclusion.billing.clone()` instead of `None` for the billing arg of `workflow_run_failed_from_error`.\n - `final_git_commit_sha`, `final_patch`, `diff_summary` stay `None` — those require the finalize-side workspace diff computation that this path deliberately skips.\n\n**B2. Drop-guard paths** (per user decision: fix them too):\n\n- `DetachedRunBootstrapGuard` (line 882-948): add an `Option` field. The bootstrap function builds the guard before the store exists, then mutates `bootstrap_guard.run_store = Some(store.clone())` once the store is in scope. On Drop, if the store is `Some`, the spawned task calls `build_conclusion_from_store` and uses its timing/billing; otherwise falls back to `RunTiming::default()` (pre-store failure means no stages can possibly exist).\n\n- `DetachedRunCompletionGuard` (line 953-1021): armed after the store exists, so add a non-optional `run_store: RunStoreHandle`. Drop's spawned task builds the conclusion and uses it.\n\n- `persist_detached_failure` (line 1023): add a `run_store: &RunStoreHandle` parameter. Call `build_conclusion_from_store` and forward `timing` + `billing` to the failure event. Update the two callers (postrun-related) to pass the store they already have in scope.\n\n`RunStoreHandle` is already `Clone` (the surrounding code clones it routinely), so move-into-spawned-task is fine.\n\n### Critical existing utilities to reuse (do not duplicate)\n\n- `fabro_types::StageTiming::new(wall, inference, tool)` and `RunTiming::new(...)` — invariant-enforcing constructors at `lib/crates/fabro-types/src/timing.rs:38, 91`.\n- `crate::millis_u64(duration)` helper for `Duration → u64` ms in `fabro-workflow` (used widely; see `lifecycle/event.rs:80-86`).\n- `build_conclusion_from_store` at `lib/crates/fabro-workflow/src/pipeline/finalize.rs:71` already does the rollup we need on the engine-failure path.\n- `billing_rollup_from_projection` (called inside `build_conclusion_from_parts`) sums per-stage timings into `RunTiming` — no need to reimplement.\n\n## Tests\n\n- **`fabro-agent` unit test**: feed `Session` a fake `LlmClient` whose `stream` sleeps a known duration and a fake tool that sleeps another known duration. Drive one `process_input_with_runtime` call. Assert `session.last_input_timing()` reports both non-zero and roughly matching the sleeps. Then call again and assert it's per-call (not cumulative).\n- **`fabro-workflow` handler tests**: in `handler/agent.rs`'s test module, wire a `CodergenBackend` that returns `CodergenResult::Text { timing: StageTiming::new(0, 200, 300), .. }` and assert `AgentHandler::execute`'s returned `Outcome.timing` carries those values. Mirror for `prompt.rs` and `fan_in.rs`. Add a `command.rs` test that mocks a `sandbox.exec_command_streaming` returning `duration_ms = 500` and asserts `outcome.timing.tool_time_ms == 500`.\n- **Executor integration**: add a test in `fabro-workflow` (or extend an existing one in `pipeline/finalize.rs` tests) that runs a tiny graph with a handler producing `Outcome.timing = Some(StageTiming::new(0, 100, 50))` and asserts the emitted `stage.completed` event carries those values, and that `run.completed` carries the summed rollup.\n- **`persist_terminal_engine_failure` test**: seed a `RunStore` with a couple of `stage.completed` events whose timing is non-zero, drive the engine-failure path, and assert the emitted `WorkflowRunFailed` event has `timing.inference_time_ms` and `tool_time_ms` matching the per-stage sum and `billing` populated.\n- **Drop guard tests**: trickier because of `Handle::try_current` + spawn. Add focused tests that arm a guard, drop it, and `tokio::task::yield_now().await` enough times to let the spawned task run, then assert the emitted failure event carries non-zero timing.\n- Run `cargo nextest run -p fabro-agent -p fabro-workflow -p fabro-store -p fabro-core`.\n- Run formatter and lints per CLAUDE.md: `cargo +nightly-2026-04-14 fmt --check --all` and `cargo +nightly-2026-04-14 clippy --workspace --all-targets -- -D warnings`.\n\n## End-to-end verification\n\n1. Build the server: `cargo build -p fabro-server`.\n2. Start server: `fabro server start`.\n3. Run a small agent-backed workflow (e.g. `fabro run repl` with a short prompt that fires at least one tool call).\n4. `fabro events --json | jq -s '[.[] | select(.event==\"stage.completed\")] | .[].properties.timing'` — confirm `inference_time_ms > 0` and `tool_time_ms > 0` for the agent stage.\n5. `fabro events --json | jq -s '[.[] | select(.event==\"run.completed\" or .event==\"run.failed\")] | .[].properties.timing'` — confirm `active_time_ms == inference_time_ms + tool_time_ms` and both are non-zero.\n6. Open the run in the web UI (start the SPA dev build per CLAUDE.md or rebuild the embedded SPA with `cargo dev build`), hover the Duration chip, confirm **Active (inference + tools)** is non-zero.\n7.

Summary of cleanups applied based on the three reviewers' findings:\n\n## Fixed\n\n1. **Returned timing from `process_input_with_runtime` instead of stashing it on `Session`** (Agent 2 #1). Dropped `last_input_inference_duration` / `last_input_tool_duration` fields, the `last_input_timing()` getter, and the per-call reset prologue. Signature is now `-> (SessionInputTiming, Result<(), Error>)`. Eliminates the \"must read immediately\" implicit contract.\n\n2. **Replaced the `record_inference_duration!` macro with a free function** `record_elapsed(&mut Option, &mut Duration)` (Agent 1 #2, Agent 2 #2). Same 7 call sites, but type-checked, IDE-discoverable, and no macro hygiene.\n\n3. **Made `run_store` required on `DetachedRunBootstrapGuard::arm()`** (Agent 1 #7, Agent 2 #3/#5). Dropped the `Option` field and the external setter pattern. Drop impl unconditionally builds the conclusion now.\n\n4. **Extracted `emit_workflow_run_failed` helper** (Agent 1 #7, Agent 2 #4). Collapses the four near-identical \"build conclusion → emit run.failed\" sites in `start.rs` (terminal engine failure, both Drop guards, `persist_detached_failure`) into one shared function.\n\n5. **Added `StageTiming::active_only(inference, tool)` constructor** (Agent 1 #1). Removed the local `active_stage_timing` helper in `handler/llm/api.rs` and unified `acp.rs` and `command.rs` on the same shape.\n\n6. **Reverted `Box` in `CodergenResult::Text`** (Agent 1 #6, Agent 2 #6). Was the worst of both worlds — didn't equalise variant size, forced `.map(|usage| *usage)` ceremony at every call site. Used `#[allow(clippy::large_enum_variant, reason = \"...\")]` matching the established pattern in `event/events.rs` and `event/sink.rs`.\n\n7. **Hoisted `test_usage` and `mark_run_running` to `test_support`** (Agent 1 #3/#4). `test_usage` was duplicated in 4 files (this PR was about to add a 5th); the 4th `mark_run_running` copy was right next to a pre-existing 3-event seed in test_support that didn't quite match. Both are now public helpers in `crate::test_support`.\n\n## Skipped (with reason)\n\n- **Make Drop guard tasks survive runtime shutdown** (Agent 3 #3) — flagged as a correctness-on-shutdown concern, not introduced by this PR; widening it would be a separate fix.\n- **`wait_for_conclusion` polling timeout hardening** (Agent 2 #8) — minor CI flake risk; current 50ms budget is enough for unit tests.\n- **`Candidate::timing` zero on LLM-failure heuristic fallback** (Agent 2 #9, Agent 3 implicit) — agent itself noted this is acceptable; capturing wasted inference on errors would require threading Instants through the fan-in evaluator.\n- **Helper for the 3-line failed-outcome decoration in agent.rs/prompt.rs** (Agent 2 #7/#10) — marginal benefit not worth the indirection.\n\n## Verification\n\n- `cargo +nightly-2026-04-14 clippy --workspace --all-targets -- -D warnings` clean\n- `cargo +nightly-2026-04-14 fmt --check --all` clean\n- `cargo nextest run -p fabro-workflow -p fabro-agent -p fabro-types -p fabro-core` — all 3592 tests pass (1175 + 1844 + 573 across the affected crates).", + "last_response": "All six fixes landed, with net **-57 lines** even while adding three shared helpers and a constructor.

Verified on `01KSE2PAVXD56N4TWNK4T5H5VA`: 10 stage.completed events and 1 run.failed event all carry `inference_time_ms: 0, tool_time_ms: 0`, even though stages like `implement@1` (94 min wall) and `simplify_opus@1` (29 min wall) were doing nothing but inference and tool calls.\n\nTwo independent bugs:\n\n1. **No production handler ever populates `Outcome.timing`.** The plumbing from `Outcome.timing` → `NodeResult` (`lib/crates/fabro-core/src/executor.rs:30-37`) → `StageTiming` → `stage.completed` props → projection → billing rollup → run.completed/failed → UI is fully wired and shipped as of #343 (2026-05-21), but `AgentHandler::execute`, `PromptHandler::execute`, `CommandHandler::execute`, and `FanInHandler` all build `Outcome::success()` and never touch `.timing`. The executor falls back to zero, and every downstream consumer faithfully aggregates zero.\n\n2. **`persist_terminal_engine_failure` and its sibling Drop-guard failure paths discard timing/billing entirely.** When the engine returns `Err` (e.g. `VisitLimitExceeded`, which is what killed the user's run), `lib/crates/fabro-workflow/src/operations/start.rs:284-308` builds a `Conclusion` via `build_conclusion_from_store`, then throws it away (`let _conclusion = ...`) and emits `WorkflowRunFailed` with `RunTiming::wall_only(...)` and `None` for billing/diff. The three Drop-guard paths (`start.rs:934`, `1001`, `1033`) do similar with `RunTiming::default()` and never even build a conclusion.\n\nGoal: stage and run events carry real per-stage `inference_time_ms` + `tool_time_ms`; engine-failure terminal events preserve the conclusion's rolled-up timing and billing.\n\n## Approach\n\n### Part A — Capture inference + tool time in handlers (Bug 1)\n\n**A1. `fabro-agent` — accumulate per-input timing in `Session`**\n\n`lib/crates/fabro-agent/src/session.rs`\n\nAdd two `Duration` accumulators to `Session` (initialised to `Duration::ZERO`):\n- `last_input_inference_duration`\n- `last_input_tool_duration`\n\nIn `process_input_with_runtime` (line 1196), zero them at entry so each call's totals are independent.\n\nIn `run_single_input` (line 1254):\n- Wrap the inference span: capture `Instant::now()` immediately before opening the stream at line 1391, and add `.elapsed()` to `last_input_inference_duration` once `response = Some(resp)` (line 1487-1490) OR when the loop exits with an error/cancellation. The whole `'streamattempts` loop counts as inference work — retries included.\n- Wrap the tool span around `execute_tool_calls` at line 1705-1719: `Instant::now()` before, accumulate `.elapsed()` after `.await`.\n\nExpose a getter:\n```rust\npub fn last_input_timing(&self) -> SessionInputTiming { ... }\n```\nwhere `SessionInputTiming { pub inference: Duration, pub tool: Duration }` is a new tiny struct in `fabro-agent`.\n\n**A2. `fabro-workflow` — thread timing through the backend boundary**\n\n`lib/crates/fabro-workflow/src/handler/agent.rs`\n\nExtend `CodergenResult::Text` with a `timing: fabro_types::StageTiming` field (wall is irrelevant — see note below). Update the few `CodergenResult::Text { ... }` constructions found by the explore agent to populate it; existing match-bindings only read `text`/`usage`/`files_touched` so they keep compiling with `..` patterns. `CodergenResult::Full(outcome)` keeps current behaviour — the outcome itself already carries any timing.\n\nNote on wall: `lib/crates/fabro-core/src/executor.rs:30-37` reads ONLY `inference_time_ms` and `tool_time_ms` out of `outcome.timing`. The wall comes from the executor's own stopwatch. So we construct `StageTiming::new(0, inference_ms, tool_ms)` and document that the wall field is ignored in this hop.\n\n`lib/crates/fabro-workflow/src/handler/llm/api.rs`\n\n- `AgentApiBackend::run` (line 1103): after `session.process_input_with_runtime(...)` returns, read `session.last_input_timing()` and set the new `timing` on `CodergenResult::Text` at line 1094.\n- `AgentApiBackend::one_shot` (line 994): wrap the `complete_one_shot_request` call at line 1053 with `Instant::now()` / `.elapsed()`. Accumulate across repair iterations of the surrounding loop. All of it counts as inference; no tool work happens in `one_shot`. Set `timing` on `CodergenResult::Text` at line 1094.\n\n`lib/crates/fabro-workflow/src/handler/llm/acp.rs`\n\n`AgentAcpBackend::run` (line ~140): already exposes `result.duration_ms`. Set `timing: StageTiming::new(0, duration_ms, 0)` on the returned `CodergenResult::Text` (per user decision: attribute all ACP duration to inference; ACP is opaque about the split).\n\n**A3. Consume timing in stage handlers and set `outcome.timing`**\n\n- `lib/crates/fabro-workflow/src/handler/agent.rs:341` — after building `outcome`, before the final `Ok(outcome)`, set `outcome.timing = Some(timing_from_codergen_result)`.\n- `lib/crates/fabro-workflow/src/handler/prompt.rs:180` — same pattern.\n- `lib/crates/fabro-workflow/src/handler/fan_in.rs:266` — backend returns timing; pass it onto the outcome built from the fan-in response.\n- `lib/crates/fabro-workflow/src/handler/command.rs:175` — `outcome.timing = Some(StageTiming::new(0, 0, result.duration_ms))`. All command wall-time is tool time. `result.duration_ms` is already at line 154 in scope.\n\nOther handlers (`human`, `wait`, `conditional`, `parallel`, `start`, `exit`, `structured_output`, `manager_loop`) do no inference or tool work. Leave `outcome.timing` as `None`; the executor will naturally produce `inference: 0, tool: 0` for those stages, which is correct.\n\n### Part B — Preserve conclusion timing on engine failure (Bug 2)\n\n`lib/crates/fabro-workflow/src/operations/start.rs`\n\n**B1. Main path** (`persist_terminal_engine_failure`, line 274-308):\n- Rename `_conclusion` → `conclusion` and use it:\n - Pass `conclusion.timing` (already a `RunTiming` with the proper inference/tool/wall rollup from `build_conclusion_from_parts`) instead of `RunTiming::wall_only(...)`.\n - Pass `conclusion.billing.clone()` instead of `None` for the billing arg of `workflow_run_failed_from_error`.\n - `final_git_commit_sha`, `final_patch`, `diff_summary` stay `None` — those require the finalize-side workspace diff computation that this path deliberately skips.\n\n**B2. Drop-guard paths** (per user decision: fix them too):\n\n- `DetachedRunBootstrapGuard` (line 882-948): add an `Option` field. The bootstrap function builds the guard before the store exists, then mutates `bootstrap_guard.run_store = Some(store.clone())` once the store is in scope. On Drop, if the store is `Some`, the spawned task calls `build_conclusion_from_store` and uses its timing/billing; otherwise falls back to `RunTiming::default()` (pre-store failure means no stages can possibly exist).\n\n- `DetachedRunCompletionGuard` (line 953-1021): armed after the store exists, so add a non-optional `run_store: RunStoreHandle`. Drop's spawned task builds the conclusion and uses it.\n\n- `persist_detached_failure` (line 1023): add a `run_store: &RunStoreHandle` parameter. Call `build_conclusion_from_store` and forward `timing` + `billing` to the failure event. Update the two callers (postrun-related) to pass the store they already have in scope.\n\n`RunStoreHandle` is already `Clone` (the surrounding code clones it routinely), so move-into-spawned-task is fine.\n\n### Critical existing utilities to reuse (do not duplicate)\n\n- `fabro_types::StageTiming::new(wall, inference, tool)` and `RunTiming::new(...)` — invariant-enforcing constructors at `lib/crates/fabro-types/src/timing.rs:38, 91`.\n- `crate::millis_u64(duration)` helper for `Duration → u64` ms in `fabro-workflow` (used widely; see `lifecycle/event.rs:80-86`).\n- `build_conclusion_from_store` at `lib/crates/fabro-workflow/src/pipeline/finalize.rs:71` already does the rollup we need on the engine-failure path.\n- `billing_rollup_from_projection` (called inside `build_conclusion_from_parts`) sums per-stage timings into `RunTiming` — no need to reimplement.\n\n## Tests\n\n- **`fabro-agent` unit test**: feed `Session` a fake `LlmClient` whose `stream` sleeps a known duration and a fake tool that sleeps another known duration. Drive one `process_input_with_runtime` call. Assert `session.last_input_timing()` reports both non-zero and roughly matching the sleeps. Then call again and assert it's per-call (not cumulative).\n- **`fabro-workflow` handler tests**: in `handler/agent.rs`'s test module, wire a `CodergenBackend` that returns `CodergenResult::Text { timing: StageTiming::new(0, 200, 300), .. }` and assert `AgentHandler::execute`'s returned `Outcome.timing` carries those values. Mirror for `prompt.rs` and `fan_in.rs`. Add a `command.rs` test that mocks a `sandbox.exec_command_streaming` returning `duration_ms = 500` and asserts `outcome.timing.tool_time_ms == 500`.\n- **Executor integration**: add a test in `fabro-workflow` (or extend an existing one in `pipeline/finalize.rs` tests) that runs a tiny graph with a handler producing `Outcome.timing = Some(StageTiming::new(0, 100, 50))` and asserts the emitted `stage.completed` event carries those values, and that `run.completed` carries the summed rollup.\n- **`persist_terminal_engine_failure` test**: seed a `RunStore` with a couple of `stage.completed` events whose timing is non-zero, drive the engine-failure path, and assert the emitted `WorkflowRunFailed` event has `timing.inference_time_ms` and `tool_time_ms` matching the per-stage sum and `billing` populated.\n- **Drop guard tests**: trickier because of `Handle::try_current` + spawn. Add focused tests that arm a guard, drop it, and `tokio::task::yield_now().await` enough times to let the spawned task run, then assert the emitted failure event carries non-zero timing.\n- Run `cargo nextest run -p fabro-agent -p fabro-workflow -p fabro-store -p fabro-core`.\n- Run formatter and lints per CLAUDE.md: `cargo +nightly-2026-04-14 fmt --check --all` and `cargo +nightly-2026-04-14 clippy --workspace --all-targets -- -D warnings`.\n\n## End-to-end verification\n\n1. Build the server: `cargo build -p fabro-server`.\n2. Start server: `fabro server start`.\n3. Run a small agent-backed workflow (e.g. `fabro run repl` with a short prompt that fires at least one tool call).\n4. `fabro events --json | jq -s '[.[] | select(.event==\"stage.completed\")] | .[].properties.timing'` — confirm `inference_time_ms > 0` and `tool_time_ms > 0` for the agent stage.\n5. `fabro events --json | jq -s '[.[] | select(.event==\"run.completed\" or .event==\"run.failed\")] | .[].properties.timing'` — confirm `active_time_ms == inference_time_ms + tool_time_ms` and both are non-zero.\n6. Open the run in the web UI (start the SPA dev build per CLAUDE.md or rebuild the embedded SPA with `cargo dev build`), hover the Duration chip, confirm **Active (inference + tools)** is non-zero.\n7. For Bug 2: force an engine failure by setting a very low visit limit and rerunning the same workflow; confirm the `run.failed` event timing breakdown is non-zero and matches the per-stage sum.\n\n## Out of scope\n\n- Adding `wall_time_ms` correctness to `Outcome.timing` (executor ignores it; doc tweak only if necessary).\n- Surfacing inference vs tool split for ACP backend beyond \"all-inference\" attribution.\n- Backfilling timing for historical runs that have already emitted zero events — past events are immutable.\n- Web UI changes beyond what the existing popover already renders.\n", + "thread.simplify_gpt.current_node": "verify", "failure_signature": "", "response.simplify_opus": "All six fixes landed, with net **-57 lines** even while adding three shared helpers and a constructor. Summary of cleanups applied based on the three reviewers' findings:\n\n## Fixed\n\n1. **Returned timing from `process_input_with_runtime` instead of stashing it on `Session`** (Agent 2 #1). Dropped `last_input_inference_duration` / `last_input_tool_duration` fields, the `last_input_timing()` getter, and the per-call reset prologue. Signature is now `-> (SessionInputTiming, Result<(), Error>)`. Eliminates the \"must read immediately\" implicit contract.\n\n2. **Replaced the `record_inference_duration!` macro with a free function** `record_elapsed(&mut Option, &mut Duration)` (Agent 1 #2, Agent 2 #2). Same 7 call sites, but type-checked, IDE-discoverable, and no macro hygiene.\n\n3. **Made `run_store` required on `DetachedRunBootstrapGuard::arm()`** (Agent 1 #7, Agent 2 #3/#5). Dropped the `Option` field and the external setter pattern. Drop impl unconditionally builds the conclusion now.\n\n4. **Extracted `emit_workflow_run_failed` helper** (Agent 1 #7, Agent 2 #4). Collapses the four near-identical \"build conclusion → emit run.failed\" sites in `start.rs` (terminal engine failure, both Drop guards, `persist_detached_failure`) into one shared function.\n\n5. **Added `StageTiming::active_only(inference, tool)` constructor** (Agent 1 #1). Removed the local `active_stage_timing` helper in `handler/llm/api.rs` and unified `acp.rs` and `command.rs` on the same shape.\n\n6. **Reverted `Box` in `CodergenResult::Text`** (Agent 1 #6, Agent 2 #6). Was the worst of both worlds — didn't equalise variant size, forced `.map(|usage| *usage)` ceremony at every call site. Used `#[allow(clippy::large_enum_variant, reason = \"...\")]` matching the established pattern in `event/events.rs` and `event/sink.rs`.\n\n7. **Hoisted `test_usage` and `mark_run_running` to `test_support`** (Agent 1 #3/#4). `test_usage` was duplicated in 4 files (this PR was about to add a 5th); the 4th `mark_run_running` copy was right next to a pre-existing 3-event seed in test_support that didn't quite match. Both are now public helpers in `crate::test_support`.\n\n## Skipped (with reason)\n\n- **Make Drop guard tasks survive runtime shutdown** (Agent 3 #3) — flagged as a correctness-on-shutdown concern, not introduced by this PR; widening it would be a separate fix.\n- **`wait_for_conclusion` polling timeout hardening** (Agent 2 #8) — minor CI flake risk; current 50ms budget is enough for unit tests.\n- **`Candidate::timing` zero on LLM-failure heuristic fallback** (Agent 2 #9, Agent 3 implicit) — agent itself noted this is acceptable; capturing wasted inference on errors would require threading Instants through the fan-in evaluator.\n- **Helper for the 3-line failed-outcome decoration in agent.rs/prompt.rs** (Agent 2 #7/#10) — marginal benefit not worth the indirection.\n\n## Verification\n\n- `cargo +nightly-2026-04-14 clippy --workspace --all-targets -- -D warnings` clean\n- `cargo +nightly-2026-04-14 fmt --check --all` clean\n- `cargo nextest run -p fabro-workflow -p fabro-agent -p fabro-types -p fabro-core` — all 3592 tests pass (1175 + 1844 + 573 across the affected crates).", "internal.run_id": "01KSGHHBR7DQ1RHFYKD7P46R6F", "internal.retry_count.preflight_lint": 0, "internal.retry_count.implement": 0, "thread.preflight_lint.current_node": "implement", + "internal.retry_count.verify": 0, "thread.implement.current_node": "simplify_opus" }, "node_outcomes": { @@ -1212,6 +1420,14 @@ "total_usd_micros": 4885902 } }, + "verify": { + "status": "succeeded", + "context_updates": { + "command.output": "blob://sha256/dadf10e5135a6e1f3f0d7a88bd81fbc3cb82b8de6434e903365683528903553d" + }, + "notes": "Script completed: git fetch origin main 2>&1 && git merge --no-edit --no-stat origin/main 2>&1 && cargo +nightly-2026-04-14 fmt --all 2>&1 && cargo dev docs refresh 2>&1 && cargo +nightly-2026-04-14 fmt --check --all 2>&1 && { command -v rg >/dev/null 2>&1 || { echo 'rg is required for verify'; exit 127; }; } && !
