Problem

• A project that ingested once and went quiet still gets a full sandbox and model session, and the scan ends with nothing to suggest. The agent is right to refuse; there was nothing to suggest a scout for.
• The only eligibility gate on ingestion is Team.ingested_event, a lifetime flag. It removed the never-ingested projects and nothing else.
• Those wasted scans take slots from projects that would get a usable batch: the US coordinator has run at its per-tick cap since tier 2 opened.
• Sizing, thresholds, and the evidence behind them are in the issue.

Closes #104517

Origin

• Scout: a custom scout
• First signal: 2026-09-22
• Inbox report: open
• Task started by: auto-start, after the report was rated P2 and ready to fix

Changes

• A dispatch-time activity check on the candidates the planner picks, not over the pool: one bounded ClickHouse read per picked candidate per tick, counting events and distinct active days over the project and its child environments together.
• A project under either line is stamped with a new low_activity status instead of scanned. The planner then leaves it alone until its refresh window passes and re-checks it, so a project that picks up traffic is scanned one window later.
• The stamp keeps any prior items, the same as failed, and leaves the failure breaker alone — a quiet project is not a broken one.
• A skipped project emits $scout_suggestions_generated with status = skipped, skip_reason = low_activity, and the two measured numbers, so the saving reads off the same event completed runs use. Both emitters now go through one function.
• The coordinator overselects the plan 2x, so a tick still fills when several candidates are skipped.

Defaults, all signals-scout-suggestions payload knobs, parsed with the same defensive clamping as the rest:

+ activity_window_days: 14
+ min_events_in_window: 100        # 0 disables the volume check
+ min_active_days_in_window: 3     # 0 disables the spread check

Deliberately unchanged:

Path	Behavior
team_allowlist projects	Scanned whatever the read says (dogfood, support)
Manual "Suggest a scout" refresh	Untouched — the person asked for the scan
A read that fails or times out	Dispatches anyway; the coordinator has already stamped the refresh window
A read that hits the row cap	Counts as active — the numbers are then a floor that clears every threshold

Mechanical: plan_suggestion_runs takes a limit; the migration is choices-only and emits no SQL; the generated signals API types pick up the new enum member.

How did you test this code?

• products/signals/backend/test/test_scout_suggestions.py, run locally, all green. Also ran posthog/temporal/tests/ai/test_module_integrity.py and hogli lint:tach.
• New coverage and the regression each group catches:
  • TestTeamIsActiveEnough — a threshold read as strict/inclusive the wrong way, or a capped read treated as quiet, would skip an active project. Parameterized over both lines, the boundary, the capped read, and each knob at 0.
  • TestSelectTeamsToScan — a quiet project still being dispatched, an allowlisted project being skipped, a low_activity stamp clobbering prior items or bumping the breaker, a failed read costing a project its refresh window, and overselected candidates past the cap being read and stamped anyway.
  • TestReadTeamActivity (ClickHouse-backed) — the SQL scoping: events in a child environment must count, events in an unrelated team must not, and events outside the window must not. No existing test touches this query.
  • TestPlanSuggestionRuns — a low_activity row must wait the full refresh window, not the short stale one, or the check would re-read every tick; and limit must override the per-tick cap, which is what makes overselect work.
  • TestSuggestionSettings — the three new knobs parse and clamp.
• Not done: no manual run against a live stack, so run_scout_suggestions --plan and the post-deploy read described in the issue are unverified.

Docs update

Updated products/signals/backend/scout_harness/AGENTS.md and products/signals/backend/management/AGENTS.md in this PR. No user-facing docs change: the strip shows nothing either way.

🤖 Agent context

Autonomy: Fully autonomous

Agent: Claude Code, Opus 5

Skills invoked: /django-migrations, /writing-tests, /reviewing-with-coderabbit, /writing-pr-descriptions.

CodeRabbit CLI pass: unavailable in this sandbox (cr is not on PATH and flox is not installed), so the PR opens without a local pass. No agent review was substituted for it.

Two decisions worth a reviewer's attention:

• The issue asked for the ClickHouse read in its own Temporal activity. It sits inside the existing planning activity instead, whose start_to_close_timeout went from 2 to 5 minutes. A separate activity per candidate would add a round trip each and buys nothing here — the read is bounded and the planning activity already heartbeats. Say so if you want it split.
• The new PlanSuggestionsOutput.skipped_team_ids field defaults to an empty list, so a plan recorded before this change still replays deterministically across the deploy; the workflow's only new branch reads that field.

Public artifact: no material outside this repository went into the diff, the tests, or this description. The fixtures are invented.

🚨 Comment density — 9% of added code lines are comments (46 of 537)

This section warns when comments are more than 3% of the code lines a PR adds, and alerts above 6%. Before agent-assisted PRs, the typical share was about 2%. Only full-line comments count. Docstrings, generated files, snapshots, migrations, and workflow files are left out.

Comments that restate the code, record how the change came about, or narrate the next line add noise for the next reader. Keep the comments that explain a reason the code cannot show, and remove the rest. See .agents/skills/writing-code-comments/SKILL.md for the house rules.

✅ Toolbar bundle — eager 2.36 MiB within budget

What the toolbar ships to customer pages, measured from the esbuild output (minified, post-tree-shake). The eager set is the entry plus everything statically imported from it — fetched before any feature runs; deferred chunks load lazily. The eager guardrail is 5.72 MiB. Each output file must also stay below 10 MB, where CloudFront stops compressing it. The module boundary is enforced separately by check-toolbar-graph.

📝 Walkthrough

Walkthrough

Scout suggestion planning now over-selects candidates and applies dispatch-time activity checks. Configured thresholds use a bounded 1–90 day window. Low-activity projects receive the low_activity status while preserving prior suggestions and failure counters. Allowlisted projects, failed reads, and capped reads remain dispatchable. Coordinator and command outputs report skipped teams. Shared telemetry records generation outcomes. Tests cover configuration, selection, persistence, and activity aggregation.

Priority: ➖ Normal

Merge Risk: 🔵 Low · up to cf238

Rare overlapping scans can hide newer suggestions, retries can repeat activity-check work, and screen-reader users are not notified when a scan becomes low activity. Address these issues before relying on the new dispatch behavior broadly.

532-543: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Tag the activity read with product and feature.

When no enclosing tag context supplies these values, sync_execute raises in local non-test debug mode. select_teams_to_scan catches the error and dispatches the run, so the activity filter is bypassed.

Use existing query-tagging enum values. Feature.SIGNALS_SCOUT_SUGGESTIONS is not declared.

149-151: 🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Prevent retries after low-activity side effects.

select_teams_to_scan writes LOW_ACTIVITY and emits $scout_suggestions_generated before the planning activity returns. If the worker fails or the activity times out after these operations, Temporal retries the activity and repeats the ClickHouse reads and skip events. The status update is repeatable, but the telemetry event is not.

Set maximum_attempts=1. The 30-minute coordinator schedule can re-plan the lost tick without replaying these side effects.

Deterministic gates denied this PR outright: it has unresolved merge conflicts, includes a database migration (deny-listed), and is sized/scoped beyond the automated-approval tier.

Gates denied the PR at the prerequisite level (unresolved merge conflicts) and it also matches the migrations deny-list and was classified T2-never, so it is outside the scope of automated approval regardless of diff content.

Guard the low-activity write against a newer scan.

select_teams_to_scan reads activity before _record_low_activity calls mark_low_activity. The row lock starts only inside mark_low_activity, which unconditionally sets LOW_ACTIVITY and last_completed_at. A concurrent scan can complete between these operations, so the stale decision can hide its newer result. Make the update conditional on the expected decision stamp, and emit skip telemetry only when the update succeeds.

Update the desktop suggestion status contract

Issue description

The API can now return low_activity, but products/desktop/packages/api-client/src/posthog-client.ts still defines ScoutSuggestionSet.status as "fresh" | "stale" | "failed" | "empty". scoutGet casts the response without validation, so TypeScript treats a valid server response as impossible. This can cause incorrect exhaustive handling in desktop consumers.

Why we think it's a valid issue

• Checked: the server path that produces the status, the desktop type mirror, and every desktop reader of that field.
• Found: low_activity is absent from _EXPIRING_STATUSES at products/signals/backend/scout_harness/suggestions.py:936, so effective_status returns it unchanged at products/signals/backend/scout_harness/suggestions.py:944-948, and the serializer at products/signals/backend/scout_suggestions_api.py:129 puts it on the wire. The premise holds: the handwritten union at products/desktop/packages/api-client/src/posthog-client.ts:685 still lists only four values, and scoutGet casts the body without validation at products/desktop/packages/api-client/src/posthog-client.ts:2486.
• Found: no desktop code branches on the field. The only reader is the EMPTY_SET default at products/desktop/packages/ui/src/features/scouts/hooks/useScoutSuggestions.ts:16, which sets "empty" and stays valid. ScoutsFleetView.tsx:186 reads suggestions?.items only. So there is no exhaustive switch to break today, and the desktop typecheck passes either way.
• Found: the other two mirrors of this union did get the new member — products/signals/frontend/generated/api.schemas.ts:5711 and services/mcp/src/api/generated.ts:87362 — and the main frontend handles the value at products/signals/frontend/inbox/components/config/scouts/ScoutSuggestionsStrip.tsx:129. The desktop mirror is the one copy left behind.
• Impact: the type now understates the server contract. Nothing misbehaves at run time and nothing fails to compile, so the cost is latent: the next desktop author who narrows on status gets a union that excludes a value the server sends. The fix is one union member plus the comment.
• Priority: lowered to consider. The drift is real and one line to correct, but I confirmed zero affected consumers, so it does not meet the should_fix bar of a broken caller or a changed invariant other code relies on.

Suggested fix

Add "low_activity" to the desktop ScoutSuggestionSet.status union and update its comment. Then run the desktop typecheck.

## Context
@products/signals/backend/models.py#L3131-3132

<issue_description>
The API can now return `low_activity`, but `products/desktop/packages/api-client/src/posthog-client.ts` still defines `ScoutSuggestionSet.status` as `"fresh" | "stale" | "failed" | "empty"`. `scoutGet` casts the response without validation, so TypeScript treats a valid server response as impossible. This can cause incorrect exhaustive handling in desktop consumers.

<issue_validation>
- **Checked:** the server path that produces the status, the desktop type mirror, and every desktop reader of that field.
- **Found:** `low_activity` is absent from `_EXPIRING_STATUSES` at `products/signals/backend/scout_harness/suggestions.py:936`, so `effective_status` returns it unchanged at `products/signals/backend/scout_harness/suggestions.py:944-948`, and the serializer at `products/signals/backend/scout_suggestions_api.py:129` puts it on the wire. The premise holds: the handwritten union at `products/desktop/packages/api-client/src/posthog-client.ts:685` still lists only four values, and `scoutGet` casts the body without validation at `products/desktop/packages/api-client/src/posthog-client.ts:2486`.
- **Found:** no desktop code branches on the field. The only reader is the `EMPTY_SET` default at `products/desktop/packages/ui/src/features/scouts/hooks/useScoutSuggestions.ts:16`, which sets `"empty"` and stays valid. `ScoutsFleetView.tsx:186` reads `suggestions?.items` only. So there is no exhaustive `switch` to break today, and the desktop typecheck passes either way.
- **Found:** the other two mirrors of this union did get the new member — `products/signals/frontend/generated/api.schemas.ts:5711` and `services/mcp/src/api/generated.ts:87362` — and the main frontend handles the value at `products/signals/frontend/inbox/components/config/scouts/ScoutSuggestionsStrip.tsx:129`. The desktop mirror is the one copy left behind.
- **Impact:** the type now understates the server contract. Nothing misbehaves at run time and nothing fails to compile, so the cost is latent: the next desktop author who narrows on `status` gets a union that excludes a value the server sends. The fix is one union member plus the comment.
- **Priority:** lowered to `consider`. The drift is real and one line to correct, but I confirmed zero affected consumers, so it does not meet the `should_fix` bar of a broken caller or a changed invariant other code relies on.
