Removed the `next_node_id` branch and the `checkpoint.completed_nodes` walk.\n- Replaced `active_stage_state_from_events` with `stage_status_from_events` that scans `stage.started`/`stage.retrying`/`stage.completed`/`stage.failed` and falls back to projection completion only when no lifecycle events exist.\n\n### Demo fixtures (step 5)\n- 4 single-visit entries get `@1` suffix; first 4 marked `Succeeded`, fifth `apply-changes@2` marked `Running` to demo the multi-visit path.\n\n### Frontend (steps 6–10)\n- `stage-sidebar.ts`: pass through `visit`/`nodeId`, filter by `node_id`, dropped `?? stage.id` fallback.\n- `stage-sidebar.tsx`: `Stage` interface — `nodeId: string`, `visit: number`; render `${name} (${visit})` when `visit > 1`.\n- `run-events.ts`: added `stage_id?: string` to payload; `stageIdFromPayload` prefers `stage_id`; added `stage.retrying` to `STAGE_EVENTS`.\n- `run-stages.tsx`: filter events by `e.stage_id === stageId`; dropped `@1` fallbacks (use `stageId` parameter); header renders visit suffix when `visit > 1`.\n- `run-overview.tsx`: replaced 3 separate dot-id sets with `aggregateGraphNodeStatus()` (latest active visit wins; otherwise latest visit's terminal state; click target = latest visit).\n\n### Tests (step 11)\n- Server (`tests.rs`): added `list_run_stages_distinguishes_visits`, `list_run_stages_shows_retrying_after_failed_event`, `list_run_stages_shows_retrying_when_failed_will_retry`. Updated existing test to emit scoped events. Added `append_scoped_stage_event` helper.\n- Web tests:\n  - `lib/run-events.test.tsx`: `queryKeysForRunEvent` covers `stage.retrying`; SSE envelope with `stage_id: verify@2` invalidates `stageTurns(runId, \"verify@2\")` and not `verify`.\n  - `lib/stage-sidebar.test.ts` (new): map two visits → distinct entries; visibility filter on `node_id`; `aggregateGraphNodeStatus` covers all four cascade cases.\n  - `routes/run-stages.test.ts`: `turnsFromEvents` filters on `stage_id` (no cross-contamination between `verify@1`/`verify@2`); command turn carries the requested `stageId` without `@1` fallback.\n\n### Verification\n- `cargo build --workspace` ✅\n- `cargo nextest run --workspace` ✅ (5066 pass, 0 fail)\n- `cargo +nightly-2026-04-14 clippy --workspace --all-targets -- -D warnings` ✅\n- `cargo +nightly-2026-04-14 fmt --check --all` ✅\n- `bun run typecheck` ✅\n- `bun test` ✅ (165 pass, up from 152)",

Skipped the test-builder duplication, the `Stage.id` vs `nodeId+visit` redundancy, and the trailing-newline notes — those are larger refactors out of scope for this pass.\n\n### Fixed\n\n1. **Eliminated JSON round-trip in duration extraction** (`lib/crates/fabro-workflow/src/lib.rs`)\n   - Both `extract_stage_durations_from_events` and `extract_stage_durations_by_stage_id` were serializing each event to `serde_json::Value` and looking up `\"duration_ms\"` as `u64`. Replaced with a typed `EventBody::StageCompleted(props) | StageFailed(props) => Some(props.duration_ms)` match in a shared helper. Removes per-event JSON allocation on a per-request hot path and removes the stringly-typed `event_name() != \"stage.completed\"` compares.\n\n2. **Fixed O(stages × events) in `list_run_stages`** (`lib/crates/fabro-server/src/server/handler/billing.rs`)\n   - Replaced `stage_status_from_events(events, stage_id, projection)` (called per stage, each scanning the full event log) with a single forward pass `latest_stage_states(events) -> HashMap<StageId, StageState>` that overwrites earlier lifecycle entries. Per-stage lookup is now O(1).\n   - Dropped the dead `_ => StageState::Pending` arm in the lifecycle match (unreachable after the prefilter) by inverting the helper to return `Option<StageState>`.\n   - Deduplicated the double `stage_id.node_id().to_string()` allocation per stage.\n\n3. **Extracted `formatStageLabel` helper** (`apps/fabro-web/app/lib/stage-sidebar.ts`)\n   - The `stage.visit > 1 ? \\`${name} (${visit})\\` : name` formula was duplicated in `stage-sidebar.tsx` and `run-stages.tsx`. Now lives in `stage-sidebar.ts` and is used in both places.\n\n4. **Single-pass graph aggregation** (`apps/fabro-web/app/lib/stage-sidebar.ts`)\n   - `aggregateGraphNodeStatus` was building a `Map<nodeId, Stage[]>`, sorting each list, then doing `[...list].reverse().find(...)` to find the latest active visit. Replaced with a single pass tracking `latest` and `latestActive` per nodeId — no sort, no array copy, no spread.\n\n5. **`stageIdFromPayload` correctness fix** (`apps/fabro-web/app/lib/run-events.ts`)\n   - The fallback returned a bare `node_id` (e.g. `\"verify\"`) when `stage_id` was absent. Under the new scheme, cache keys are suffixed (`stageTurns(runId, \"verify@1\")`), so a bare `node_id` never matches and invalidations would silently no-op. Now returns `undefined` if `stage_id` isn't present, which matches the existing test assertion that bare `verify` should NOT appear in invalidated keys.\n\n### Verification\n\n- `cargo nextest run -p fabro-server -p fabro-workflow` → 1498 passed\n- `cargo clippy --all-targets -D warnings` (changed crates) → clean\n- `cd apps/fabro-web && bun run typecheck` → clean\n- `cd apps/fabro-web && bun test` → 165 passed",
+          "graph.goal": "# Stage URLs encode visit (`node@visit`)\n\n## Context\n\nToday, in the Fabro web UI, stages that re-run (e.g. `verify` in a loop) all\ncollapse to the same URL: `/runs/{id}/stages/verify`. The sidebar lists them\nmultiple times but every link/selection points at the first visit.\n\nA **Stage** is a Node + a Visit (1-indexed; bumped each time the workflow\nre-enters that node). The data model already knows this:\n`StageId(node_id, visit)` exists in `lib/crates/fabro-types/src/stage_id.rs`,\nand the OpenAPI `StageId` path parameter\n(`docs/public/api-reference/fabro-api.yaml:2925`) already documents the\n`node_id@visit` form. The bug is that `GET /api/v1/runs/{id}/stages` returns\n`RunStage.id = node_id` (no visit suffix), and the events fallback in the UI\nfilters by `node_id` instead of the full `stage_id`.\n\nNote: \"visit\" is deliberate. There is a separate retry-attempt counter\ninside a single visit (`StageStartedProps.attempt` in\n`lib/crates/fabro-types/src/run_event/stage.rs:13`) — that's not what we're\nmodeling here. URLs and the new field both refer to **visits**.\n\nOutcome: each stage gets a distinct URL (e.g. `verify@1`, `verify@2`) that\nloads only that visit's turns/logs, with a `(N)` indicator in the sidebar\nwhen `N > 1`.\n\n## Approach\n\n**Server**: rebuild the stage list from `RunProjection::iter_stages()`, which\nis already keyed by full `StageId` (`HashMap<StageId, StageProjection>` in\n`lib/crates/fabro-types/src/run_projection.rs:32`). This deletes the\n`checkpoint.completed_nodes` walk (which loses visit info — it's a\n`Vec<String>` of node_ids only) and the `next_node_id` branch entirely.\n\n**Status derivation is event-driven, not completion-driven.**\n`StageProjection.completion` is set by `StageFailed` *even when* the workflow\nis about to retry (`run_state.rs:329` — `StageRetrying` does not clear it),\nso reading completion alone would show `failed` for a stage that's\nretrying. For each stage, scan its events (filtered by exact `stage_id`)\nand take the **latest** lifecycle event:\n- `stage.retrying` → `StageState::Retrying`\n- `stage.failed(props)` with `props.will_retry == true` → `StageState::Retrying`\n- `stage.failed(props)` with `props.will_retry == false` → `StageState::Failed`\n- `stage.completed` → `StageState::from(StageCompletedProps.status)`\n- `stage.started` (no later completed/failed/retrying) → `StageState::Running`\n\nUse the projection's `completion` only as a tiebreaker when no lifecycle\nevents for that stage_id exist (defensive case). The\n`StageState::from(StageOutcome)` impl is at\n`lib/crates/fabro-types/src/outcome.rs:136`.\n\n**API contract**: on `RunStage`, add a required `visit: integer` field, and\n**rename `dot_id` → `node_id`** (required) for consistency with\n`StageId::node_id()`, `EventEnvelope.node_id`, and the rest of the type\nvocabulary. Tighten the `id` description to call out the `node_id@visit`\nform. This is a breaking field rename; per project policy\n(\"simplest change possible, we don't care about migration\"), we do it now\nrather than carrying both names.\n\n**Frontend**: links and selection already use `stage.id`, so they propagate\nnaturally once the API returns `verify@1`/`verify@2`. The events-fallback\nfilter switches from `e.node_id === stageId` to `e.stage_id === stageId`.\nSidebar/header append `(N)` only when `visit > 1`. The\n`isVisibleStage(stage.id)` filter switches to `isVisibleStage(stage.node_id)`\nso that `start@1`/`exit@1` are still hidden.\n\nOne fixture run with two visits of the same node is added to demo data so\nthis code path stays under test.\n\n## Files to change (in order)\n\n### 1. OpenAPI — `docs/public/api-reference/fabro-api.yaml`\n\n`RunStage` schema (line 6315):\n- `id`: clarify description: `StageId in \"node_id@visit\" form, e.g. verify@2`. Update example to `verify@2`.\n- Add `visit: { type: integer, format: uint32, minimum: 1, description: \"1-based visit count; bumped each time the workflow re-enters this node\" }`. Mark required. (`format: uint32` + `minimum: 1` codegens to `NonZeroU32`, matching `StageProjection.first_event_seq` at line 5286–5288 of the spec.)\n- **Rename `dot_id` → `node_id`** and mark required. Description: \"Node id in the workflow graph; multiple stages with different visits share the same node_id.\" Example: `verify`.\n\n### 2. Generated code\n\n- `cargo build -p fabro-api` — regenerates Rust types via `progenitor`.\n- `cd lib/packages/fabro-api-client && bun run generate` — regenerates TS client.\n\n### 3. Workflow lib — `lib/crates/fabro-workflow/src/lib.rs`\n\nAdd a sibling to `extract_stage_durations_from_events` (line 89). Leave the\nexisting function alone — `finalize.rs:81,506` and `retro.rs:56` operate on a\nsingle visit per node and shouldn't change. New function:\n\n```rust\npub fn extract_stage_durations_by_stage_id(\n    events: &[EventEnvelope],\n) -> HashMap<StageId, u64>\n```\n\nFilters `stage.completed`/`stage.failed`, keys by `envelope.stage_id`.\n\n### 4. Server handler — `lib/crates/fabro-server/src/server/handler/billing.rs`\n\nRewrite `list_run_stages` (lines 38–126):\n\n- Replace `checkpoint.completed_nodes` iteration with\n  `projection.iter_stages()`, collected and sorted by `first_event_seq`.\n- Per stage, build `RunStage`:\n  - `id = stage_id.to_string()`\n  - `node_id = stage_id.node_id().to_string()`\n  - `name = stage_id.node_id().to_string()` (UI adds the suffix)\n  - `visit = NonZeroU32::new(stage_id.visit()).expect(\"StageId.visit is 1-based\")`\n    (generated type is `NonZeroU32` because of `format: uint32` + `minimum: 1`)\n  - `status = stage_status_from_events(events, &stage_id, &projection)`\n    (see Status derivation below)\n  - `duration_secs`: from the new `extract_stage_durations_by_stage_id`.\n- **Status derivation** — replace `active_stage_state_from_events` (line 19)\n  with `stage_status_from_events(events: &[EventEnvelope], stage_id: &StageId,\n  projection: &RunProjection) -> StageState`. Implementation:\n  1. Filter events to those with `envelope.event.stage_id == Some(stage_id)`.\n  2. Find the **latest** lifecycle event among `stage.started`,\n     `stage.retrying`, `stage.completed`, `stage.failed` for that stage_id.\n  3. Map:\n     - `stage.started` → `Running`\n     - `stage.retrying` → `Retrying`\n     - `stage.failed(props)` with `props.will_retry == true` → `Retrying`\n       (a will-retry failure is conceptually mid-retry, even before the\n       `stage.retrying` envelope lands; field defined at\n       `lib/crates/fabro-types/src/run_event/stage.rs:57`)\n     - `stage.failed(props)` with `props.will_retry == false` → `Failed`\n     - `stage.completed` → `StageState::from(StageCompletedProps.status)`\n       (using the existing `From<StageOutcome> for StageState` impl)\n  4. Fallback: if no lifecycle events, use\n     `StageState::from(completion.outcome)` from the projection if present,\n     else `Pending`.\n- Drop the `next_node_id` branch (lines 113–123) entirely — the projection\n  now carries the in-flight stage.\n\n### 5. Demo fixtures — `lib/crates/fabro-server/src/demo/mod.rs:1156`\n\nSuffix existing four IDs with `@1` and set `visit: 1`. Add a 5th entry to\nmodel a re-run:\n\n```rust\nfn visit(n: u32) -> NonZeroU32 { NonZeroU32::new(n).expect(\"visit is 1-based\") }\n\nRunStage { id: \"apply-changes@1\".into(), name: \"apply-changes\".into(),\n           status: Succeeded, duration_secs: Some(118.0),\n           node_id: \"apply\".into(), visit: visit(1) },\nRunStage { id: \"apply-changes@2\".into(), name: \"apply-changes\".into(),\n           status: Running, duration_secs: None,\n           node_id: \"apply\".into(), visit: visit(2) },\n```\n\n`visit` codegens to `NonZeroU32` (see Section 1) — direct `1`/`2` literals\nwon't compile. Use the helper above (or inline\n`NonZeroU32::new(n).unwrap()`).\n\nBoth share `node_id: \"apply\"` so the graph node lights up regardless of\nselection.\n\n### 6. Frontend mapping — `apps/fabro-web/app/lib/stage-sidebar.ts:13`\n\n- Pass through `visit` and `node_id` (renamed from `dot_id`) to the sidebar\n  `Stage` shape.\n- Change filter to `isVisibleStage(stage.node_id)` (line 17) so suffixed IDs\n  still hide `start`/`exit`.\n- Drop the `?? stage.id` fallback (line 21) — `node_id` is now required.\n\n### 7. Sidebar component — `apps/fabro-web/app/components/stage-sidebar.tsx`\n\n- Rename the `dotId` field on `Stage` to `nodeId` (line 21).\n- Add `visit: number` to the `Stage` interface (line 16).\n- Render display label as `${stage.name}` when `visit <= 1`, otherwise\n  `${stage.name} (${visit})` in the `<span>` at line 103.\n- Update any callers reading `stage.dotId` (graph highlighting) to\n  `stage.nodeId`.\n\n### 8. SSE cache invalidation — `apps/fabro-web/app/lib/run-events.ts`\n\nTwo fixes here:\n\n1. **Suffixed StageId routing** (`:132`): `stageIdFromPayload` currently\n   returns `payload.node_id`. Once\n   `queryKeys.runs.stageTurns(runId, stageId)` is keyed by `verify@1` (lines\n   84, 95 of the same file), invalidations passing `verify` won't match.\n   - Add `stage_id?: string` to `RunEventPayload` (line 14).\n   - In `stageIdFromPayload`: prefer `payload.stage_id`; fall back to\n     `payload.node_id` for events that don't carry the full StageId (e.g.\n     pre-stage envelopes).\n2. **Add `stage.retrying` to `STAGE_EVENTS`** (line 35). Today the set is\n   `[\"stage.started\", \"stage.completed\", \"stage.failed\"]`. The new\n   server-side status logic relies on `stage.retrying`, and the workflow\n   already emits it (`lib/crates/fabro-workflow/src/lifecycle/event.rs:232`).\n   Without this, a selected stage stays visually `failed` until another\n   invalidating event arrives — defeats the P1 fix above.\n\nTests:\n- An envelope with `stage_id: \"verify@2\"` and `event: \"stage.retrying\"`\n  invalidates `stages`, `events`, `graph`, run `detail`, and\n  `stageTurns(runId, \"verify@2\")`.\n\n### 9. Run-stages route — `apps/fabro-web/app/routes/run-stages.tsx`\n\n- Line 72: change `events.filter((e) => e.node_id === stageId)` to\n  `events.filter((e) => e.stage_id === stageId)`. The filter narrows the\n  scope so `stageId` (the function parameter) is the authoritative StageId\n  inside the loop.\n- Lines 117 and 126: drop the `` ?? `${stageId}@1` `` fallback. Note:\n  `EventEnvelope.stage_id` is generated as `string | null | undefined`\n  (see `lib/packages/fabro-api-client/src/models/run-event.ts:34`), so\n  assigning `stageId: e.stage_id` directly fails typecheck. Use the\n  function parameter instead — after the filter, all surviving events have\n  `stage_id === stageId` by construction:\n  ```ts\n  pendingCommand = { stageId, script, language };\n  ...\n  turns.push({ kind: \"command\", stageId, ... });\n  ```\n- Header (line ~640): when `selectedStage.visit > 1`, render\n  `${selectedStage.name} (${selectedStage.visit})`.\n\n### 10. Graph aggregation policy — `apps/fabro-web/app/routes/run-overview.tsx:66-77`\n\nToday the graph code maps `Map<dotId, stageId>`; with two visits sharing a\nnode_id, the second entry silently overwrites the first, and the status\nsets union all visits. Make the policy explicit:\n\n- **Click target**: open the **latest** visit for that node_id (highest\n  `visit`). Build the map deterministically — `Map.set(nodeId, latestStage.id)`\n  after sorting visits ascending.\n- **Status policy**: *latest visit wins for terminal states; active states\n  win globally.* That is — for a given node, if any visit is `running` or\n  `retrying`, the node renders that active state. Otherwise the node renders\n  the **latest visit's** terminal state. So:\n  - `(failed, running)` → `running` (active wins)\n  - `(failed, succeeded)` → `succeeded` (latest visit wins; failure-then-fix\n    should look healed, not failed)\n  - `(succeeded, failed)` → `failed` (latest visit wins)\n  - `(running, retrying)` → `retrying` (active; pick the latest)\n- The current if/else cascade in run-overview.tsx orders running before\n  failed unconditionally — switch it to a two-step compute: pick the\n  display status per node by the rule above, *then* render once.\n- **Frontend tests**: `(failed, running)` → running color, click → `verify@2`.\n  `(failed, succeeded)` → succeeded color, click → `verify@2`.\n  `(succeeded, failed)` → failed color, click → `verify@2`.\n\n### 11. Tests\n\n- **`lib/crates/fabro-server/src/server/tests.rs`** (alongside existing\n  `list_run_stages_projects_retrying_until_completion` at line 2126): add\n  `list_run_stages_distinguishes_visits` — build a run with two visits of\n  the same node, hit `GET /runs/{id}/stages`, assert two `RunStage`\n  entries with distinct `id`/`visit` and the same `node_id`.\n- **`lib/crates/fabro-server/src/server/tests.rs`**:\n  `list_run_stages_shows_retrying_after_failed_event` — a stage where the\n  latest event is `stage.failed` followed by `stage.retrying` renders as\n  `Retrying`, not `Failed`.\n- **`lib/crates/fabro-server/src/server/tests.rs`**:\n  `list_run_stages_shows_retrying_when_failed_will_retry` — a stage whose\n  *only* lifecycle event so far is `stage.failed { will_retry: true }`\n  (no `stage.retrying` envelope yet) still renders as `Retrying`. Narrower\n  guard for the will_retry branch.\n- **`apps/fabro-web/app/routes/run-stages.test.ts`**: `turnsFromEvents`\n  filters correctly on `stage_id` (verify@1 events vs verify@2 events do\n  not cross-contaminate).\n- **`apps/fabro-web/app/lib/stage-sidebar.test.ts`** (new or existing): map\n  fixture with two `apply-changes` visits → two distinct sidebar entries,\n  display labels `apply-changes` and `apply-changes (2)`.\n- **`apps/fabro-web/app/lib/run-events.test.tsx`**: SSE envelope with\n  `stage_id: \"verify@2\"` triggers invalidation of\n  `stageTurns(runId, \"verify@2\")`.\n- **Graph test** (`apps/fabro-web/app/routes/run-overview.test.tsx` or\n  similar): two visits of the same node — graph status follows the\n  cascade, click target is the latest visit.\n\n## Out of scope\n\n- Wiring up the production `/runs/{id}/stages/{stageId}/turns` handler\n  (`lib/crates/fabro-server/src/server/handler/mod.rs:116` is\n  `not_implemented`). The events fallback is doing the work today and will\n  keep doing it; the per-stage filter fix is what unblocks multi-visit\n  display.\n- Per-visit billing breakdown in `get_run_billing` — that path still uses\n  the existing per-node duration map.\n\n## Critical files\n\n- `docs/public/api-reference/fabro-api.yaml` — schema source of truth\n- `lib/crates/fabro-server/src/server/handler/billing.rs` — `list_run_stages`\n- `lib/crates/fabro-types/src/run_projection.rs` — `iter_stages` data source\n- `lib/crates/fabro-workflow/src/lib.rs` — new duration extractor\n- `lib/crates/fabro-server/src/demo/mod.rs` — fixture\n- `apps/fabro-web/app/routes/run-stages.tsx` — events filter + header\n- `apps/fabro-web/app/components/stage-sidebar.tsx` — display label\n- `apps/fabro-web/app/lib/stage-sidebar.ts` — visibility filter + mapping\n- `apps/fabro-web/app/lib/run-events.ts` — SSE cache invalidation\n- `apps/fabro-web/app/routes/run-overview.tsx` — graph aggregation policy\n- `lib/crates/fabro-types/src/outcome.rs` — `From<StageOutcome> for StageState` (already exists; reuse)\n\n## Verification\n\nBuild:\n- `cargo build -p fabro-api` — regenerates types from updated YAML\n- `cd lib/packages/fabro-api-client && bun run generate`\n- `cargo build --workspace`\n\nTests:\n- `cargo nextest run -p fabro-server` — conformance + new tests in\n  `lib/crates/fabro-server/src/server/tests.rs` (distinguish_visits,\n  shows_retrying_after_failed_event, shows_retrying_when_failed_will_retry)\n- `cd apps/fabro-web && bun test && bun run typecheck`\n\nEnd-to-end (single-visit regression):\n- `fabro server start` → open the demo URL → confirm\n  `detect-drift`/`propose-changes`/`review-changes` show no `(N)` suffix.\n  URLs are `.../stages/detect-drift@1` etc. Graph still highlights correctly.\n\nEnd-to-end (the fix):\n- Demo: two `apply-changes` rows. Sidebar shows `apply-changes` and\n  `apply-changes (2)`. URLs `.../stages/apply-changes@1` vs\n  `.../stages/apply-changes@2` are distinct and load distinct content. Graph\n  lights up the same `apply` node either way.\n- Real loop run: trigger a workflow that loops `verify` (fail → fix → pass).\n  Confirm two distinct entries with distinct statuses, durations, turns, and\n  command logs (`/stages/verify@1/logs/stdout` vs\n  `/stages/verify@2/logs/stdout`).\n\nAPI contract:\n- `curl /api/v1/runs/{id}/stages | jq` — `id` contains `@`; `visit` is\n  present and ≥ 1; `node_id` is the bare node id with no `@`. The old\n  `dot_id` field is gone.\n\nNegative checks:\n- Terminal run: no trailing in-flight row.\n- Parallel fanout: still one row per group (parallel branches don't promote\n  to separate `RunStage` entries).\n- Empty checkpoint: empty list, no panic.\n- **Retry mid-flight**: trigger a stage that fails and then retries; sidebar\n  shows `Retrying`, not `Failed`. Confirms P1 regression guard.\n- **SSE liveness**: while a run is active and a stage emits events, the\n  selected stage's turn list updates without a manual refresh — confirms\n  cache invalidation works against suffixed keys.\n",

Removed the `next_node_id` branch and the `checkpoint.completed_nodes` walk.\n- Replaced `active_stage_state_from_events` with `stage_status_from_events` that scans `stage.started`/`stage.retrying`/`stage.completed`/`stage.failed` and falls back to projection completion only when no lifecycle events exist.\n\n### Demo fixtures (step 5)\n- 4 single-visit entries get `@1` suffix; first 4 marked `Succeeded`, fifth `apply-changes@2` marked `Running` to demo the multi-visit path.\n\n### Frontend (steps 6–10)\n- `stage-sidebar.ts`: pass through `visit`/`nodeId`, filter by `node_id`, dropped `?? stage.id` fallback.\n- `stage-sidebar.tsx`: `Stage` interface — `nodeId: string`, `visit: number`; render `${name} (${visit})` when `visit > 1`.\n- `run-events.ts`: added `stage_id?: string` to payload; `stageIdFromPayload` prefers `stage_id`; added `stage.retrying` to `STAGE_EVENTS`.\n- `run-stages.tsx`: filter events by `e.stage_id === stageId`; dropped `@1` fallbacks (use `stageId` parameter); header renders visit suffix when `visit > 1`.\n- `run-overview.tsx`: replaced 3 separate dot-id sets with `aggregateGraphNodeStatus()` (latest active visit wins; otherwise latest visit's terminal state; click target = latest visit).\n\n### Tests (step 11)\n- Server (`tests.rs`): added `list_run_stages_distinguishes_visits`, `list_run_stages_shows_retrying_after_failed_event`, `list_run_stages_shows_retrying_when_failed_will_retry`. Updated existing test to emit scoped events. Added `append_scoped_stage_event` helper.\n- Web tests:\n  - `lib/run-events.test.tsx`: `queryKeysForRunEvent` covers `stage.retrying`; SSE envelope with `stage_id: verify@2` invalidates `stageTurns(runId, \"verify@2\")` and not `verify`.\n  - `lib/stage-sidebar.test.ts` (new): map two visits → distinct entries; visibility filter on `node_id`; `aggregateGraphNodeStatus` covers all four cascade cases.\n  - `routes/run-stages.test.ts`: `turnsFromEvents` filters on `stage_id` (no cross-contamination between `verify@1`/`verify@2`); command turn carries the requested `stageId` without `@1` fallback.\n\n### Verification\n- `cargo build --workspace` ✅\n- `cargo nextest run --workspace` ✅ (5066 pass, 0 fail)\n- `cargo +nightly-2026-04-14 clippy --workspace --all-targets -- -D warnings` ✅\n- `cargo +nightly-2026-04-14 fmt --check --all` ✅\n- `bun run typecheck` ✅\n- `bun test` ✅ (165 pass, up from 152)",

Replaced with a typed `EventBody::StageCompleted(props) | StageFailed(props) => Some(props.duration_ms)` match in a shared helper. Removes per-event JSON allocation on a per-request hot path and removes the stringly-typed `event_name() != \"stage.completed\"` compares.\n\n2. **Fixed O(stages × events) in `list_run_stages`** (`lib/crates/fabro-server/src/server/handler/billing.rs`)\n   - Replaced `stage_status_from_events(events, stage_id, projection)` (called per stage, each scanning the full event log) with a single forward pass `latest_stage_states(events) -> HashMap<StageId, StageState>` that overwrites earlier lifecycle entries. Per-stage lookup is now O(1).\n   - Dropped the dead `_ => StageState::Pending` arm in the lifecycle match (unreachable after the prefilter) by inverting the helper to return `Option<StageState>`.\n   - Deduplicated the double `stage_id.node_id().to_string()` allocation per stage.\n\n3. **Extracted `formatStageLabel` helper** (`apps/fabro-web/app/lib/stage-sidebar.ts`)\n   - The `stage.visit > 1 ? \\`${name} (${visit})\\` : name` formula was duplicated in `stage-sidebar.tsx` and `run-stages.tsx`. Now lives in `stage-sidebar.ts` and is used in both places.\n\n4. **Single-pass graph aggregation** (`apps/fabro-web/app/lib/stage-sidebar.ts`)\n   - `aggregateGraphNodeStatus` was building a `Map<nodeId, Stage[]>`, sorting each list, then doing `[...list].reverse().find(...)` to find the latest active visit. Replaced with a single pass tracking `latest` and `latestActive` per nodeId — no sort, no array copy, no spread.\n\n5. **`stageIdFromPayload` correctness fix** (`apps/fabro-web/app/lib/run-events.ts`)\n   - The fallback returned a bare `node_id` (e.g. `\"verify\"`) when `stage_id` was absent. Under the new scheme, cache keys are suffixed (`stageTurns(runId, \"verify@1\")`), so a bare `node_id` never matches and invalidations would silently no-op. Now returns `undefined` if `stage_id` isn't present, which matches the existing test assertion that bare `verify` should NOT appear in invalidated keys.\n\n### Verification\n\n- `cargo nextest run -p fabro-server -p fabro-workflow` → 1498 passed\n- `cargo clippy --all-targets -D warnings` (changed crates) → clean\n- `cd apps/fabro-web && bun run typecheck` → clean\n- `cd apps/fabro-web && bun test` → 165 passed",

Removed the `next_node_id` branch and the `checkpoint.completed_nodes` walk.\n- Replaced `active_stage_state_from_events` with `stage_status_from_events` that scans `stage.started`/`stage.retrying`/`stage.completed`/`stage.failed` and falls back to projection completion only when no lifecycle events exist.\n\n### Demo fixtures (step 5)\n- 4 single-visit entries get `@1` suffix; first 4 marked `Succeeded`, fifth `apply-changes@2` marked `Running` to demo the multi-visit path.\n\n### Frontend (steps 6–10)\n- `stage-sidebar.ts`: pass through `visit`/`nodeId`, filter by `node_id`, dropped `?? stage.id` fallback.\n- `stage-sidebar.tsx`: `Stage` interface — `nodeId: string`, `visit: number`; render `${name} (${visit})` when `visit > 1`.\n- `run-events.ts`: added `stage_id?: string` to payload; `stageIdFromPayload` prefers `stage_id`; added `stage.retrying` to `STAGE_EVENTS`.\n- `run-stages.tsx`: filter events by `e.stage_id === stageId`; dropped `@1` fallbacks (use `stageId` parameter); header renders visit suffix when `visit > 1`.\n- `run-overview.tsx`: replaced 3 separate dot-id sets with `aggregateGraphNodeStatus()` (latest active visit wins; otherwise latest visit's terminal state; click target = latest visit).\n\n### Tests (step 11)\n- Server (`tests.rs`): added `list_run_stages_distinguishes_visits`, `list_run_stages_shows_retrying_after_failed_event`, `list_run_stages_shows_retrying_when_failed_will_retry`. Updated existing test to emit scoped events. Added `append_scoped_stage_event` helper.\n- Web tests:\n  - `lib/run-events.test.tsx`: `queryKeysForRunEvent` covers `stage.retrying`; SSE envelope with `stage_id: verify@2` invalidates `stageTurns(runId, \"verify@2\")` and not `verify`.\n  - `lib/stage-sidebar.test.ts` (new): map two visits → distinct entries; visibility filter on `node_id`; `aggregateGraphNodeStatus` covers all four cascade cases.\n  - `routes/run-stages.test.ts`: `turnsFromEvents` filters on `stage_id` (no cross-contamination between `verify@1`/`verify@2`); command turn carries the requested `stageId` without `@1` fallback.\n\n### Verification\n- `cargo build --workspace` ✅\n- `cargo nextest run --workspace` ✅ (5066 pass, 0 fail)\n- `cargo +nightly-2026-04-14 clippy --workspace --all-targets -- -D warnings` ✅\n- `cargo +nightly-2026-04-14 fmt --check --all` ✅\n- `bun run typecheck` ✅\n- `bun test` ✅ (165 pass, up from 152)"
