Admin form writers need warm-up and readback

Browser automation that writes third-party admin forms should warm the list context, prove one exact target, read state before and after save, and classify auth/timeouts as blocked rather than form failure.

Agent hosts need bounded polling by default

Artifact retention must protect referenced images

Retention policies must protect images and artifacts still referenced by active services, rollback targets, or recovery plans. Otherwise cleanup breaks rollback during the incident that needs it.

Bun module mocks can leak across same-process test files

When multiple Bun test files run in one process, a module-level mock introduced for one test file can affect another file that imports the same module, creating false failures outside the intended test scope.

Dropdown form submits can vanish when the menu unmounts

A native form placed inside a dropdown, popover, command menu, or context menu can lose its submit path if the menu closes and unmounts before the browser or framework dispatches the submit/mutation. The UI may look clicked while no API request is sent.

Hot count polling can become the data import incident

Polling exact target-table counts for a live import progress display can create more database load than the import itself. Progress should come from job-owned counters, watermarks, sampled metrics, or terminal summaries unless an exact count is proven cheap.

Idempotent reruns can replace separate resume state in imports

Inventory imports need target reconciliation before apply

Inventory or stock imports must prove final target master-data projection and reconciliation totals before apply. Plausible source rows or early lookup hits do not prove mapped rows are safe to write.

Long-running HTTP handlers are fragile batch runners

A large import or backfill should not depend on one HTTP request staying open through a load balancer or proxy. Use a resident worker or short start request plus durable progress and idempotent resume behavior.

Long-running probes need safe progress output

Mailbox folder moves are not retention or provider deletion

Moved UI tests need absence and presence assertions

Operational queues need wake-one and backup paths

Adding a wait queue around a shared operational choke point is not enough. The queue needs FIFO no-overtake, wake-one handoff, backup retry, and a strict wait-is-not-authorization boundary.

Import progress state must match cursor semantics

Progress artifacts must be visible from the runtime that displays them

Internal capability is not external authorization — modeling something is not doing it outside

The deploy loop has hidden costs — and the cache is rarely where they live

External APIs care about timezones and nesting — and they will not tell you nicely

Post-merge checkout errors are ambiguous — check the remote before rolling back

Detached HEAD work must be anchored to a branch before normal push

Modern Node CJS require(esm) may return a namespace object, not ERR_REQUIRE_ESM

Pydantic v2 moved BaseSettings to pydantic-settings
