# Wiki Log

Append-only chronological record. Each entry: `## [YYYY-MM-DD] <op> | <subject>`.
Query with `grep "^## \[" log.md | tail -5`.

## [2026-06-14] ingest | Parking System — Architecture & Design Notes
First source ingested. Bootstrapped wiki scaffolding (CLAUDE.md schema, index.md,
overview.md, log.md). Created source summary, 14 entity pages, 9 concept pages, and
decision records (settled decisions + 6 open questions). Source is a dense design
doc covering stack, threat model, device architecture, UHPPOTE access control, the
custom ESP32 controller alternative, readers, and a reference BOM.

## [2026-06-15] decision | JWT key choice + ESP32 deferred
From app work, not a new source. Added [[open-questions]] #7 (symmetric vs.
asymmetric JWT signing key — raised by the commit security review; prefer RS256/EdDSA
so verifying hosts hold only a public key, mirroring the ATECC608 / challenge-response
property). Marked [[esp32-custom-controller]] `status: deferred` per decision not to
implement device-level auth for now (access control stays on UHPPOTE + network
isolation); noted in [[open-questions]] #6. Updated [[local-jwt-auth]] (hardened secret
handling + 8h expiry, asymmetric-key pointer) and the index.

## [2026-06-15] decision | Device-agnostic registry + first-run setup
From app work. Made the [[device-adapter-pattern]] selectable: added a
[[device-registry]] (catalog of drivers per category) and a [[first-run-setup]]
flow so the admin picks a device per lane at install. Categories: access
(ZKTeco / ESP32 relay), reader (Wiegand / TCP-IP), camera (Hikvision / Dahua,
snapshot-on-event), printer. Added a `CameraDevice` interface; new `lane_devices`
+ `setup_state` tables (migration 0001); admin-only setup endpoints. Stub drivers
for now (no real vendor protocols yet). Verified catalog + assign + validation +
auth end to end.
