Moves the agent model out of env-only config into an admin-editable Settings
section, and enforces is_admin for the first time — it has been in the schema
since migration 0001, plumbed to the client, and checked nowhere.
Backend:
- Migration 0010: instance_settings, a single-row (CHECK id=1) table — pansy's
first instance-level state. Holds agent_model ('' = inherit env) and
agent_enabled (NULL = inherit env), version-guarded like every mutable row.
SECRETS STAY IN ENV: OLLAMA_CLOUD_API_KEY is never stored here.
- requireAdmin at the service seam (authoritative) plus a cheap middleware
early-403. Non-admin gets 403, not 404 — settings existence isn't masked.
- EffectiveAgent resolves DB-over-env (model, enabled); key always from env.
- The live Runner is hot-swapped, not built once. agentHolder holds it behind
an atomic.Pointer; the chat routes are now registered UNCONDITIONALLY and
nil-check agent.get(), so a settings change turns the assistant on/off/onto a
new model with no restart and no race against in-flight readers. /capabilities
reads the pointer, so it reports what's live, not what booted.
- internal/agentmodel is a new leaf package holding the one place that knows how
to turn a spec into a model. Both agent (to run) and service (to validate a
spec before storing it) import it; it can't live in agent, which imports
service. Settings PATCH validates the spec via Parse, so a typo is a 400 now
rather than a broken assistant on the next turn.
Frontend:
- /settings route (admin guard), a Settings page (model field, tri-state
enabled, live status), nav link shown only to admins.
- useCapabilities drops staleTime:Infinity — the assistant can now change under
a running page — and the settings save invalidates it.
Contract change: chat routes always exist, so "assistant off" is a runtime 503
+ capabilities:false, not a missing route. Updated the test that asserted the
old shape.
Verified live against the built binary: disable flips capabilities to false and
logs it; re-enable with a new model swaps it back; a bad spec is rejected 400;
the setting persists across a restart. Swap is race-clean under `go test -race`.

- fillLoaded's doc listed what it does and omitted the non-finite-region
rejection this PR added to it.
- Trim the half-spacing rule's restatement in DESIGN.md to the decision and a
pointer. The rule, the square-foot arithmetic and the failure mode are
written out once, in hexCenters, rather than near-verbatim in four places.

Filling a bed left the outer row too far from the edge, and staggered rows
worse still. Two defects, both from anchoring the lattice at the region's min
corner:
- Odd rows offset by `radius` started at `MinX + 2·radius`, leaving a bare
strip a whole plop wide down one side of every other row.
- All the leftover slack piled up on the far edge, where plops hung 13cm
outside the bed on a 4×8ft garlic bed. Nothing clips them, so they drew
over the bed outline.
Spacing is a constraint between neighbouring plants competing for the same
soil, light and water. A bed edge is not a competitor, so the outer row owes
it half the spacing — the arithmetic inside every square-foot-gardening chart
(4/square = 6" apart, 3" from the square's edge).
The wrinkle: a plop is a CLUMP, not a plant. defaultPlopRadius is 1.5×spacing,
so keeping the whole circle inside the bed insets the outer row by 1.5
spacings, three times what the rule allows. So centre the lattice and set the
minimum centre-inset to `radius - spacing/2`: the clump may cross the edge by
up to half a spacing, putting its outermost plants exactly the half-spacing
from the edge the rule asks for. Capped there — a clump mostly outside the bed
would be a drawing of plants in the path.
Same bed, same 15 plops, now symmetric with a deliberate 6.5cm overhang inside
the 7.5cm budget instead of an accidental 13cm on one side only. The stagger
falls out of the centring for free: an offset row holds one fewer plop, and
centring that run puts it exactly half a pitch off its neighbours.
TestFillRegionDeterministicPacking expected 4 plops in a 60×60 bed; the fourth
was centred ON the east edge with half of it outside, well past the budget.
It is 3 now — the fix working, not a regression in it.

Capture the v1 architecture: domain model, geometry, SVG editor with
semantic zoom, REST API with version-guarded sync, service-layer seam
for future majordomo/executus agent tools, OIDC-first auth (Authentik),
and the phased roadmap.
