Phased, dependency-ordered plan across 11 workstreams (foundation,
schema, auth, admin taxonomy, brigade area, search, geo/ETA, detail,
deployment, seed, tests/security) with exact file paths, code/schema
snippets, ordered tasks and per-task verification. Includes cross-cutting
standards, definition-of-done, and risks. Produced by a fan-out design +
adversarial critique + synthesis workflow.
