Periphery Engineering Brain
Know what is true, what is proposed, and what is actually built.
The Plan Room is a read-only projection. It pulls together approved Git records, Neon registry state, evidence, and repository structure without becoming another place for an agent to quietly rewrite the truth.

One authority per object
| Object | Authority | Plan Room treatment |
|---|---|---|
| Approved governance, decisions, specs, and code | Protected Git commit | Render and link to exact revision |
| Raw evidence | Immutable file plus checksum | Inventory and cite, never execute |
| Active work, leases, candidates, gates | Neon task registry | Sanitized generated snapshot |
| Operational business facts | Original business system | Link or read through scoped connector |
| Indexes, summaries, and graphs | Rebuildable projection | Clearly label as generated |
01 / Provenance
Why do we believe this?
Follow source to cited span to claim, decision, requirement, and published view.
Open graph lenses →02 / Repositories
Where does it live?
Browse the real folder tree and jump to the exact GitHub file.
Open repository map →03 / Sources
What did we actually ingest?
Inspect immutable Batch 05 files, checksums, duplicate holds, and cited chunk counts.
Open source inventory →04 / Construction
What is happening now?
Track issued packages, candidates, QC, independent inspection, and release.
Open operating flow →05 / Drawings
What are we building?
View the approved Periphery UI blueprint only after its hash is verified.
Open blueprint gallery →Green prose is not a passing inspection. Every status shown here must resolve to a source, candidate SHA, database record, or test result.
