Today a child OpenAI session can emit its own\n`todo.created` events on the same `stage_id`, replacing the root list and\ncausing later root `todo.updated` completions to be ignored. The visible\nsymptom is an agent sidebar showing a stale child TODO list such as `0/3`\ncompleted even though the root stage plan completed.\n\n## Problem Frame\n\nOpenAI `update_plan` lists are scoped per agent session as\n`openai_plan:`. A stage may contain both the root agent session and\nchild/subagent sessions. `StageProjection` currently has only one\n`todos: Option`, so the reducer must choose which list is\nthe stage-level list. The stage sidebar is a stage-agent summary, so it should\nshow the root stage session's list rather than whichever session most recently\ncreated todos.\n\n## Requirements Trace\n\n- R1. Root OpenAI plan TODOs must remain the projected `stage.todos` list even\n when child OpenAI sessions emit TODO events on the same stage.\n- R2. Later root OpenAI `todo.updated` and `todo.deleted` events must continue\n to apply after child OpenAI TODO events are observed.\n- R3. Child OpenAI TODO lists must not create, replace, or mutate\n `StageProjection.todos`.\n- R4. Anthropic task projection must remain unchanged because Anthropic task\n lists are intentionally scoped to the root session and shared across\n subagents.\n- R5. Do not change public API shapes, generated API types, or frontend\n rendering code for this fix.\n\n## Scope Boundaries\n\n- Do not add a multi-list TODO projection in this change.\n- Do not expose child/subagent TODO lists in the sidebar in this change.\n- Do not change `TodoListProjection`, `StageProjection`, or OpenAPI schemas.\n- Do not change event serialization, event names, or the agent `update_plan`\n tool behavior.\n\n## Context & Research\n\n### Relevant Code and Patterns\n\n- `lib/crates/fabro-agent/src/todo_tools.rs` scopes OpenAI plans by\n `session_id`, producing `openai_plan:`.\n- `lib/crates/fabro-types/src/run_event/mod.rs` already carries\n `session_id` and `parent_session_id` on event envelopes.\n- `lib/crates/fabro-store/src/run_state.rs` owns the persisted-event reducer\n that updates `StageProjection.todos` from `todo.created`, `todo.updated`,\n and `todo.deleted`.\n- The existing `todo_reducer` test module in `run_state.rs` is the right place\n for focused regression coverage.\n- `apps/fabro-web/app/routes/run-stages.tsx` and\n `apps/fabro-web/app/components/stage-insights-sidebar.tsx` already render\n `stage.todos`; no UI change is needed if the projection is corrected.\n\n### Observed Failing Case\n\nFor run `01KSBT48J14ZMK9HQN48SVMG3T`, stage `simplify_gpt@1` had:\n\n- Root list `openai_plan:2f4458b9-1128-4a96-8dfa-bff4b73b9c33`: five root\n todos, all completed by later `todo.updated` events.\n- Child list `openai_plan:a09b9432-823d-4068-91fa-5c6185578e8e`: three child\n todos, created with `parent_session_id` set and never updated.\n\nThe child `todo.created` events replaced `stage.todos`, so the sidebar showed\nthe child list as `0/3` even after the root list completed.\n\n## Key Technical Decisions\n\n- Use `parent_session_id` as the root-vs-child signal for OpenAI plan\n projection. A root stage session has `parent_session_id == None`; child\n sessions have `parent_session_id != None`.\n- Ignore child OpenAI plan events for `StageProjection.todos`. This preserves\n the current single-list schema while making the selected list match the\n stage sidebar's meaning.\n- Keep Anthropic task projection unchanged. Anthropic tasks use\n `anthropic_tasks:`, so child-session envelopes should still\n be allowed to update the shared root task list.\n- Treat legacy OpenAI events without `parent_session_id` as root-compatible for\n backwards compatibility.\n\n## Implementation Units\n\n- [ ] **Unit 1: Add reducer policy for projectable stage TODO events**\n\n**Goal:** Make the reducer distinguish root OpenAI plan events from child\nOpenAI plan events before mutating `stage.todos`.\n\n**Files:**\n- Modify: `lib/crates/fabro-store/src/run_state.rs`\n\n**Approach:**\n- Add a small helper near the TODO reducer functions, for example\n `should_project_stage_todo_event(stored: &RunEvent, list_kind:\n TodoListKind) -> bool`.\n- Return `false` only when `list_kind == TodoListKind::OpenAiPlan` and\n `stored.parent_session_id.is_some()`.\n- Return `true` for root OpenAI events and all Anthropic task events.\n- Call this helper in the `EventBody::TodoCreated`,\n `EventBody::TodoUpdated`, and `EventBody::TodoDeleted` match arms before\n resolving or mutating the stage projection.\n- Leave `apply_todo_created`, `apply_todo_updated`, and\n `apply_todo_deleted` focused on list mutation once the caller has decided\n the event is projectable.\n\n**Test scenarios:**\n- Root OpenAI events with no `parent_session_id` still create and update\n `stage.todos`.\n- Child OpenAI events with `parent_session_id` do not create `stage.todos`\n when no root list exists.\n- Child OpenAI events do not replace an existing root OpenAI list.\n- Root OpenAI updates still apply after ignored child OpenAI events.\n\n- [ ] **Unit 2: Add focused reducer regression tests**\n\n**Goal:** Lock the intended root-list behavior so future TODO projection work\ndoes not regress the sidebar.\n\n**Files:**\n- Modify: `lib/crates/fabro-store/src/run_state.rs`\n\n**Approach:**\n- Extend the existing `todo_reducer` module rather than creating a new test\n file.\n- Add a test helper or local event setup that sets\n `event.event.parent_session_id = Some(parent_session_id.to_string())` for\n child-session events.\n- Add one regression test that reproduces the failing sequence:\n root OpenAI creates list, child OpenAI creates a different list on the same\n stage, root OpenAI completes its items. Assert the final projection is the\n root list and all root statuses are completed.\n- Add one test proving child OpenAI events alone do not create a stage TODO\n projection.\n- Add one test proving Anthropic child-session task events still project.\n\n**Verification:**\n- `cargo nextest run -p fabro-store todo_reducer`\n- `cargo +nightly-2026-04-14 fmt --check --all`\n\n## System-Wide Impact\n\n- **API compatibility:** No response schema changes. Existing consumers of\n `StageProjection.todos` continue to receive a single list.\n- **UI behavior:** The sidebar should show the root agent's TODO progress for\n the selected stage. Child OpenAI session plans remain available only in the\n raw event stream for now.\n- **Historical runs:** Replaying existing event logs should produce corrected\n projections because the decision uses envelope fields already persisted on\n child events.\n- **Future extensibility:** If child/subagent TODO display is needed later,\n add a multi-list projection separately rather than overloading\n `stage.todos`.\n\n## Risks & Mitigations\n\n| Risk | Mitigation |\n|------|------------|\n| Some legacy child OpenAI events lack `parent_session_id` and still project as root | Accept this for backwards compatibility; only events with explicit child-session evidence are filtered. |\n| Anthropic child task updates could be accidentally filtered | Gate only `TodoListKind::OpenAiPlan`; add a regression test for `TodoListKind::AnthropicTasks`. |\n| Root list replacement semantics become ambiguous if a root stage emits multiple OpenAI list IDs | Preserve current root replacement behavior; the fix only prevents child lists from replacing root lists. |\n\n## Assumptions\n\n- `parent_session_id == None` is the canonical signal for the root stage agent\n session in stored event envelopes.\n- Child OpenAI TODO lists are not part of the current stage sidebar contract.\n- The correct near-term fix is projection selection, not a frontend workaround\n or a schema expansion.\n", - "internal.thread_id": "preflight_lint", - "internal.node_visit_count": 1, - "internal.work_dir": "/home/daytona/workspace/fabro", - "outcome": "failed", - "failure_signature": "implement|budget_exhausted|api_deterministic|openai|quota_exceeded", - "graph.rankdir": "LR", - "graph.model_stylesheet": "\n * { model: claude-opus-4-7; }\n ", "internal.retry_count.start": 0, - "internal.retry_count.preflight_compile": 0, + "thread.toolchain.current_node": "preflight_compile", + "graph.rankdir": "LR", + "internal.retry_count.implement": 0, + "failure_class": "budget_exhausted", + "graph.goal": "---\ntitle: fix: Prefer root stage TODO projection\ntype: fix\nstatus: active\ndate: 2026-05-24\n---\n\n# fix: Prefer Root Stage TODO Projection\n\n## Overview\n\nFix stage TODO projection so `StageProjection.todos` represents the selected\nstage agent's root session plan.

Today a child OpenAI session can emit its own\n`todo.created` events on the same `stage_id`, replacing the root list and\ncausing later root `todo.updated` completions to be ignored. The visible\nsymptom is an agent sidebar showing a stale child TODO list such as `0/3`\ncompleted even though the root stage plan completed.\n\n## Problem Frame\n\nOpenAI `update_plan` lists are scoped per agent session as\n`openai_plan:`. A stage may contain both the root agent session and\nchild/subagent sessions. `StageProjection` currently has only one\n`todos: Option`, so the reducer must choose which list is\nthe stage-level list. The stage sidebar is a stage-agent summary, so it should\nshow the root stage session's list rather than whichever session most recently\ncreated todos.\n\n## Requirements Trace\n\n- R1. Root OpenAI plan TODOs must remain the projected `stage.todos` list even\n when child OpenAI sessions emit TODO events on the same stage.\n- R2. Later root OpenAI `todo.updated` and `todo.deleted` events must continue\n to apply after child OpenAI TODO events are observed.\n- R3. Child OpenAI TODO lists must not create, replace, or mutate\n `StageProjection.todos`.\n- R4. Anthropic task projection must remain unchanged because Anthropic task\n lists are intentionally scoped to the root session and shared across\n subagents.\n- R5. Do not change public API shapes, generated API types, or frontend\n rendering code for this fix.\n\n## Scope Boundaries\n\n- Do not add a multi-list TODO projection in this change.\n- Do not expose child/subagent TODO lists in the sidebar in this change.\n- Do not change `TodoListProjection`, `StageProjection`, or OpenAPI schemas.\n- Do not change event serialization, event names, or the agent `update_plan`\n tool behavior.\n\n## Context & Research\n\n### Relevant Code and Patterns\n\n- `lib/crates/fabro-agent/src/todo_tools.rs` scopes OpenAI plans by\n `session_id`, producing `openai_plan:`.\n- `lib/crates/fabro-types/src/run_event/mod.rs` already carries\n `session_id` and `parent_session_id` on event envelopes.\n- `lib/crates/fabro-store/src/run_state.rs` owns the persisted-event reducer\n that updates `StageProjection.todos` from `todo.created`, `todo.updated`,\n and `todo.deleted`.\n- The existing `todo_reducer` test module in `run_state.rs` is the right place\n for focused regression coverage.\n- `apps/fabro-web/app/routes/run-stages.tsx` and\n `apps/fabro-web/app/components/stage-insights-sidebar.tsx` already render\n `stage.todos`; no UI change is needed if the projection is corrected.\n\n### Observed Failing Case\n\nFor run `01KSBT48J14ZMK9HQN48SVMG3T`, stage `simplify_gpt@1` had:\n\n- Root list `openai_plan:2f4458b9-1128-4a96-8dfa-bff4b73b9c33`: five root\n todos, all completed by later `todo.updated` events.\n- Child list `openai_plan:a09b9432-823d-4068-91fa-5c6185578e8e`: three child\n todos, created with `parent_session_id` set and never updated.\n\nThe child `todo.created` events replaced `stage.todos`, so the sidebar showed\nthe child list as `0/3` even after the root list completed.\n\n## Key Technical Decisions\n\n- Use `parent_session_id` as the root-vs-child signal for OpenAI plan\n projection. A root stage session has `parent_session_id == None`; child\n sessions have `parent_session_id != None`.\n- Ignore child OpenAI plan events for `StageProjection.todos`. This preserves\n the current single-list schema while making the selected list match the\n stage sidebar's meaning.\n- Keep Anthropic task projection unchanged. Anthropic tasks use\n `anthropic_tasks:`, so child-session envelopes should still\n be allowed to update the shared root task list.\n- Treat legacy OpenAI events without `parent_session_id` as root-compatible for\n backwards compatibility.\n\n## Implementation Units\n\n- [ ] **Unit 1: Add reducer policy for projectable stage TODO events**\n\n**Goal:** Make the reducer distinguish root OpenAI plan events from child\nOpenAI plan events before mutating `stage.todos`.\n\n**Files:**\n- Modify: `lib/crates/fabro-store/src/run_state.rs`\n\n**Approach:**\n- Add a small helper near the TODO reducer functions, for example\n `should_project_stage_todo_event(stored: &RunEvent, list_kind:\n TodoListKind) -> bool`.\n- Return `false` only when `list_kind == TodoListKind::OpenAiPlan` and\n `stored.parent_session_id.is_some()`.\n- Return `true` for root OpenAI events and all Anthropic task events.\n- Call this helper in the `EventBody::TodoCreated`,\n `EventBody::TodoUpdated`, and `EventBody::TodoDeleted` match arms before\n resolving or mutating the stage projection.\n- Leave `apply_todo_created`, `apply_todo_updated`, and\n `apply_todo_deleted` focused on list mutation once the caller has decided\n the event is projectable.\n\n**Test scenarios:**\n- Root OpenAI events with no `parent_session_id` still create and update\n `stage.todos`.\n- Child OpenAI events with `parent_session_id` do not create `stage.todos`\n when no root list exists.\n- Child OpenAI events do not replace an existing root OpenAI list.\n- Root OpenAI updates still apply after ignored child OpenAI events.\n\n- [ ] **Unit 2: Add focused reducer regression tests**\n\n**Goal:** Lock the intended root-list behavior so future TODO projection work\ndoes not regress the sidebar.\n\n**Files:**\n- Modify: `lib/crates/fabro-store/src/run_state.rs`\n\n**Approach:**\n- Extend the existing `todo_reducer` module rather than creating a new test\n file.\n- Add a test helper or local event setup that sets\n `event.event.parent_session_id = Some(parent_session_id.to_string())` for\n child-session events.\n- Add one regression test that reproduces the failing sequence:\n root OpenAI creates list, child OpenAI creates a different list on the same\n stage, root OpenAI completes its items. Assert the final projection is the\n root list and all root statuses are completed.\n- Add one test proving child OpenAI events alone do not create a stage TODO\n projection.\n- Add one test proving Anthropic child-session task events still project.\n\n**Verification:**\n- `cargo nextest run -p fabro-store todo_reducer`\n- `cargo +nightly-2026-04-14 fmt --check --all`\n\n## System-Wide Impact\n\n- **API compatibility:** No response schema changes. Existing consumers of\n `StageProjection.todos` continue to receive a single list.\n- **UI behavior:** The sidebar should show the root agent's TODO progress for\n the selected stage. Child OpenAI session plans remain available only in the\n raw event stream for now.\n- **Historical runs:** Replaying existing event logs should produce corrected\n projections because the decision uses envelope fields already persisted on\n child events.\n- **Future extensibility:** If child/subagent TODO display is needed later,\n add a multi-list projection separately rather than overloading\n `stage.todos`.\n\n## Risks & Mitigations\n\n| Risk | Mitigation |\n|------|------------|\n| Some legacy child OpenAI events lack `parent_session_id` and still project as root | Accept this for backwards compatibility; only events with explicit child-session evidence are filtered. |\n| Anthropic child task updates could be accidentally filtered | Gate only `TodoListKind::OpenAiPlan`; add a regression test for `TodoListKind::AnthropicTasks`. |\n| Root list replacement semantics become ambiguous if a root stage emits multiple OpenAI list IDs | Preserve current root replacement behavior; the fix only prevents child lists from replacing root lists. |\n\n## Assumptions\n\n- `parent_session_id == None` is the canonical signal for the root stage agent\n session in stored event envelopes.\n- Child OpenAI TODO lists are not part of the current stage sidebar contract.\n- The correct near-term fix is projection selection, not a frontend workaround\n or a schema expansion.\n", + "internal.thread_id": "implement", + "internal.node_visit_count": 1, + "internal.work_dir": "/home/daytona/workspace/fabro", + "thread.preflight_compile.current_node": "preflight_lint", + "internal.retry_count.preflight_compile": 0, + "last_response": "## Summary\n\nThe previous `implement` stage failed with `budget_exhausted` and committed only the tests, leaving the actual reducer fix missing.

Could it be a method on `RunEvent` or `TodoListKind`?\n - Redundant state / unnecessary indirection.

Today a child OpenAI session can emit its own +`todo.created` events on the same `stage_id`, replacing the root list and +causing later root `todo.updated` completions to be ignored. The visible +symptom is an agent sidebar showing a stale child TODO list such as `0/3` +completed even though the root stage plan completed. + +## Problem Frame + +OpenAI `update_plan` lists are scoped per agent session as +`openai_plan:`. A stage may contain both the root agent session and +child/subagent sessions. `StageProjection` currently has only one +`todos: Option`, so the reducer must choose which list is +the stage-level list. The stage sidebar is a stage-agent summary, so it should +show the root stage session's list rather than whichever session most recently +created todos. + +## Requirements Trace + +- R1. Root OpenAI plan TODOs must remain the projected `stage.todos` list even + when child OpenAI sessions emit TODO events on the same stage. +- R2. Later root OpenAI `todo.updated` and `todo.deleted` events must continue + to apply after child OpenAI TODO events are observed. +- R3. Child OpenAI TODO lists must not create, replace, or mutate + `StageProjection.todos`. +- R4. Anthropic task projection must remain unchanged because Anthropic task + lists are intentionally scoped to the root session and shared across + subagents. +- R5. Do not change public API shapes, generated API types, or frontend + rendering code for this fix. + +## Scope Boundaries + +- Do not add a multi-list TODO projection in this change. +- Do not expose child/subagent TODO lists in the sidebar in this change. +- Do not change `TodoListProjection`, `StageProjection`, or OpenAPI schemas. +- Do not change event serialization, event names, or the agent `update_plan` + tool behavior. + +## Context & Research + +### Relevant Code and Patterns + +- `lib/crates/fabro-agent/src/todo_tools.rs` scopes OpenAI plans by + `session_id`, producing `openai_plan:`. +- `lib/crates/fabro-types/src/run_event/mod.rs` already carries + `session_id` and `parent_session_id` on event envelopes. +- `lib/crates/fabro-store/src/run_state.rs` owns the persisted-event reducer + that updates `StageProjection.todos` from `todo.created`, `todo.updated`, + and `todo.deleted`. +- The existing `todo_reducer` test module in `run_state.rs` is the right place + for focused regression coverage. +- `apps/fabro-web/app/routes/run-stages.tsx` and + `apps/fabro-web/app/components/stage-insights-sidebar.tsx` already render + `stage.todos`; no UI change is needed if the projection is corrected. + +### Observed Failing Case + +For run `01KSBT48J14ZMK9HQN48SVMG3T`, stage `simplify_gpt@1` had: + +- Root list `openai_plan:2f4458b9-1128-4a96-8dfa-bff4b73b9c33`: five root + todos, all completed by later `todo.updated` events. +- Child list `openai_plan:a09b9432-823d-4068-91fa-5c6185578e8e`: three child + todos, created with `parent_session_id` set and never updated. + +The child `todo.created` events replaced `stage.todos`, so the sidebar showed +the child list as `0/3` even after the root list completed. + +## Key Technical Decisions + +- Use `parent_session_id` as the root-vs-child signal for OpenAI plan + projection. A root stage session has `parent_session_id == None`; child + sessions have `parent_session_id != None`. +- Ignore child OpenAI plan events for `StageProjection.todos`. This preserves + the current single-list schema while making the selected list match the + stage sidebar's meaning. +- Keep Anthropic task projection unchanged.

Search for existing utilities and helpers that could replace newly written code. Use Grep to find similar patterns elsewhere in the codebase — common locations are utility directories, shared modules, and files adjacent to the changed ones. +2.

Flag any inline logic that could use an existing utility — hand-rolled string manipulation, manual path handling, custom environment checks, ad-hoc type guards, and similar patterns are common candidates. + +Note: This is a greenfield app, so focus on maximizing simplicity and don't worry about changing things to achieve it. + +### Agent 2: Code Quality Review + +Review the same changes for hacky patterns: + +1. Redundant state: state that duplicates existing state, cached values that could be derived, observers/effects that could be direct calls +2. Parameter sprawl: adding new parameters to a function instead of generalizing or restructuring existing ones +3. Copy-paste with slight variation: near-duplicate code blocks that should be unified with a shared abstraction +4. Leaky abstractions: exposing internal details that should be encapsulated, or breaking existing abstraction boundaries +5. Stringly-typed code: using raw strings where constants, enums (string unions), or branded types already exist in the codebase + +Note: This is a greenfield app, so be aggressive in optimizing quality. + +### Agent 3: Efficiency Review + +Review the same changes for efficiency: + +1. Unnecessary work: redundant computations, repeated file reads, duplicate network/API calls, N+1 patterns +2. Missed concurrency: independent operations run sequentially when they could run in parallel +3. Hot-path bloat: new blocking work added to startup or per-request/per-render hot paths +4. Unnecessary existence checks: pre-checking file/resource existence before operating (TOCTOU anti-pattern) — operate directly and handle the error +5. Memory: unbounded data structures, missing cleanup, event listener leaks +6. Overly broad operations: reading entire files when only a portion is needed, loading all items when filtering for one + +## Phase 3: Fix Issues + +Wait for all three agents to complete.
