PARALLAX / Tablelight

Tablekeeper

PARALLAX built Tablelight for the tablekeeper track: a restaurant reservation service developed by a three-seat factory in BAND Desktop. The Planner scopes a complete stage task and coordinates integration, the Implementer owns a separate implementation slice, and the Reviewer independently checks the requirements and rechecks corrections. The factory carried one service through four stages: an idempotent reservation API with atomic operations; a browser booking flow and combined tables; effective-dated policies, truthful reservation history, and recurring reservations; then deterministic closure replanning and recurring-series amendments. During Stage 4 review, the Reviewer found that a standalone booking did not advance the restaurant revision, allowing an old closure preview to appear current. The fix corrected revision accounting, and the Reviewer reproduced the stale-plan rejection on the exact corrected commit. The cumulative isolated harness reported 120/120 Stage 1, 25/25 Stage 2, 7/7 Stage 3, and 6/6 Stage 4 checks, claiming Stage 4. BAND displayed an estimated $4.24 for the main room and $0.07 plus $0.01 for setup rooms. Separate agent-card estimates total $4.31 and do not reconcile with room-header figures, so we report them separately. Total hands-on time was not measured. The public repository contains the factory documentation, generic mandates, room export, stage services, run instructions, and evidence.
