agents can manage the calendar and the address book

the owner's scenario: any chat, "I'm having dinner Saturday with my wife, add
that", "cancel it", "add Peter Griffin, this number" — and it happens.

reading already worked through the JSON api. writing is the DAV door, and the
credential question is what took the thinking: every option meant a NEW secret
and then somewhere to keep it — a file, the secret store, one per commander —
each a password to distribute, rotate and eventually leak.

$OFFICER_AGENT_KEY is already in every agent's environment, already bound to one
user, already revoked when the session ends. so the DAV door accepts it as the
basic-auth password, and no new secret exists anywhere.

it cannot reach another account, and that is structural rather than a check:
resolveApiKey says whose the key is and that id becomes X-Remote-User. the URL
is never consulted, radicale refuses any other principal, and the username in
the header must AGREE with the key rather than select the account. verified —
own principal 207/201, another account 403, spoofed username 401.

the permission check is isApiRequestAllowed against this plugin's own prefix, so
the answer is exactly what the gate would give the same credential at
/api/caldav. a second copy of that rule is the copy that stops being updated.
DAV methods are mapped to read/write with PROPFIND and REPORT as reads —
unmapped they counted as writes and a member with read could not list their own
calendar. anything unrecognised defaults to write, which is the safe direction.

the skill is written from recipes that were RUN, not recalled: create 201, move
204 (same UID, same href, SEQUENCE bumped), delete 200, contact create and
delete, and the json read for lookups.

the trap it exists to prevent, found while testing rather than by reading:
`date -u -d 'saturday 20:00'` does not convert. -u parses AND prints as UTC, so
8pm becomes 20:00Z, which is 21:00 in lisbon. every event an hour out, nothing
errors, and it is invisible until someone is stood up. the two-step through
epoch is the only form that works and the skill leads with it.

How long a provisioning link lives.
Five minutes until 2026-08-27, which assumed the person minting the link is the person clicking it —
true for a button in the UI, false for every other way this gets used. Handing a URL to someone who then
has to pick up a phone, open Safari and type it took longer than that every single time, and the failure
is indistinguishable from a broken profile: the link 404s and iOS says "Invalid Profile", which sends you
looking at the plist rather than at the clock. That cost most of an evening.
Thirty minutes, still single-use. The link embeds a live password, so this is a real trade — but the
binding constraint is that it is claimed ONCE and then gone, not that the window is narrow.

* So CardDAV gets its own profile, with its own PayloadIdentifier, which iOS has nothing to merge into.
