⚠️ Duplication (Python) — 2 new duplicated blocks (worst 168 tokens)
New Python code duplication introduced by this branch. Fails at 70+ tokens in app code, or 150+ tokens when both copies live in test files. Advisory while the gate proves itself: extract a shared helper instead of copying.

✅ 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.

AddField:
This operation acquires a brief lock but doesn't rewrite the table.
Deployment uses lock timeouts with automatic retries, so lock contention will cause retries rather than connection pile-up.

The verifier sends the complete agent-authored HogQL and free-text criteria to TypeSafe, but this validation only checks the query length and window placeholders. A query containing a literal email, URL, property value, or identifier therefore passes validation and is disclosed to the third party. Parse and reject sensitive query constructs, or send a sanitized structural description instead of the raw query.
How this was verified: The persisted query receives no content validation beyond placeholder checks and is copied unchanged into the TypeSafe request payload.

Registering verification_query in the shared check schema makes this internal kind available through scout-report-check-create. A scout can supply any same-team merged PR ID, and execution verifies neither that the PR is linked to this report nor that the check came from automatic scheduling. A mistaken or manipulated scout can therefore run verification against an unrelated merge window. Restrict scout-authored checks to metric_threshold and agent, or enforce the report-to-PR link during creation and execution.

When a stored verification config is malformed or becomes stale, this fallback places empty strings in required UUID fields. Constructing VerificationResult then raises inside the transaction and rolls back the check-state update. The outer loop only logs that failure, leaving the check active and overdue so it fails on every coordinator tick until expiry. Preserve valid nullable provenance or record the error without constructing an invalid result.

The backend returns snapshot and current-result columns and values to authorized viewers, but the timeline shows only the snapshot row count and omits current_result entirely. Operators can see the verdict but cannot inspect the evidence behind it. Render both result tables and their windows while preserving the existing hidden-data state for unauthorized viewers.

Unlike metric checks, verification checks receive no coordinator deadline. A slow HogQL query followed by the 30-second provider request can overrun the 120-second tick budget and delay every later check. Pass the deadline through verification execution and derive query and provider timeouts from the remaining budget.

367-371: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winThe snapshot line pluralizes incorrectly and reports 0 rows for a gated viewer.
Two issues on the same line. A single row renders "1 rows". A viewer without HogQL snapshot access receives
rows: []from the serializer, so the line claims "0 rows" while the window is still shown, which reads as an empty snapshot rather than a hidden one. Pluralize the count and omit it whencontent.queryis absent.♻️ Proposed fix

🚀 Performance & Scalability | 🟠 Major | ⚡ Quick win
An errored verification check retries hourly for 14 days and bypasses the error cap.
The branch re-arms on verdict.outcome != "passed", which includes errored. A deterministic failure - a deleted verification artefact, a pull request that is no longer merged, or an organization without AI data processing approval - therefore repeats every hour until the horizon, roughly 336 attempts. MAX_CONSECUTIVE_CHECK_ERRORS and CHECK_ERROR_RETRY_AFTER never apply, because this branch returns before the error path at Lines 347-359. The PR objectives describe retrying not-solved and inconclusive results only.
Route the errored outcome through the existing error path.

Problem
Signals reports stop at merge, so operators cannot tell whether a deployed fix changed the behavior that caused the report.
Deployment lag and delayed user traffic make a one-time check unreliable, especially for client releases.
Note
Treat this PR as a demo branch. It proves the local workflow, data contract, and UI, but it does not provision production credentials or roll out the feature.
Changes
Trying the demo
TYPESAFE_API_KEY=op://<vault>/<item>/<field>to the gitignored.env.local; never paste or commit the resolved value.hogli start. The launcher detects the reference and resolves it withop run --env-file=.env.local.verification_queryartefact before associating and merging the implementation pull request.verification_result. Inconclusive and not-solved results continue to refresh hourly.TYPESAFE_BASE_URLdefaults tohttps://api.typesafe.ai, andTYPESAFE_DEFAULT_MODELdefaults tojev-latest, so the API key is the only required local setting.The resolved key stays in the application process environment. The egress transport adds it as a bearer token only when sending the request. The raw key is not stored in Signals artefacts or used as a telemetry label; rate limiting uses a short SHA-256 fingerprint instead.
A deployed environment must provide its own
