Grounding (F2–F5): - Each ground_dinner job carries the dinner's new grounding_revision (migration 0010). Renaming a pending Regular raises the revision, and a job only grounds and writes a dinner still at its revision, so a queued original job no longer grounds the new name or decides the outcome. - Background grounding keeps a method, minutes or difficulty a member saved while the Regular was pending, and fills only those left empty. - Grounding by hand clears the pasted recipe_url, and link deduplication uses the source_url of the attached recipe, else the pending link. - Archived dinners are not grounded: the job checks before any search, fetch or model call, and its final update requires an unarchived row. Onboarding (F6, F7): - Step 3 shows "Add Regulars" back to step 2 when the server refuses to finish with fewer than three Regulars. - Common picks are hidden by a copy of harness Normalize/Similar, checked against the same shared cases as the Go code. Docs (F8): ARCHITECTURE.md covers the three-Regular minimum, step-3 recovery, the grounding revision and the dedupe rules. F1 was fixed in 1304487; its test now also asserts the old link is never grounded and recipe_url stays cleared. Maestro task 5037ff86-181d-448e-927b-c2fd2258a25d.
