Tablet 46: the watch — rate limits at every gate, per IP at the pe'ah, per key inside

Tamid §1.1 wrote the pe'ah's limit (10/min, 100/h per IP); nothing
enforced it, on any tier, and every admitted request spends manna.

VavPipeline.BigdeiKodesh.Mishmar: fixed minute and hour windows per
subject in ETS, the subject stored only as sha256(boot salt, tier,
subject) — no IP and no key is ever in memory as itself, the sweep
drops closed windows, nothing survives a restart (the Tamid's "not
logged beyond the current request", kept in memory too). A refused
knock is not counted. 429 RATE_LIMITED with Retry-After and the manna
explanation (Shemot 16:18). Pe'ah per peer address; courtyard and
chatzer per key, after the gate (a wrong key is 401 and never counted).
Numbers: pe'ah 10/100 (Tamid), courtyard 20/200 and chatzer 5/60
(from Construction §2.3; config :rate_limits).

Service shorashim-external: externalTrafficPolicy Local. With Cluster
the pod saw every caller as the node, 91.92.153.113 (observed via
/proc/net/tcp) — a per-IP limit would have been one bucket for the
world.
