Photograph a seed packet → it fills in the plant and the purchase. This is the
backend; the scan UI is a follow-up PR.
Vision model config (mirrors the agent model from #79):
- Migration 0011 adds instance_settings.vision_model; PANSY_VISION_MODEL is the
env default. Precedence Settings → env → empty; the KEY stays in the env.
- EffectiveVision resolves it; /capabilities advertises "vision" only when a
model + key are configured, so the UI offers the scan button only when it works.
Extraction is one-shot, NOT an agent loop (internal/vision):
- majordomo.Generate[SeedPacket] derives a JSON schema from the struct tags and
hands the image to the vision model; it can't call a tool, so it can't touch
the garden — it only reads a picture and returns data. Numeric fields are
pointers, so a field the packet doesn't print comes back nil, not a made-up 0.
- Hermetic test: majordomo's fake provider returns canned packet JSON and
Generate unmarshals it, image + derived schema included. No live model.
The image is normalized to JPEG at the upload boundary (imagenorm from #80),
which is where an iPhone HEIC becomes readable — majordomo's media path can't
decode HEIC. imagenorm now links into the binary (~7 MB, the cost #80 deferred).
The hard part is catalog matching, not OCR (internal/service/seed_packet.go):
- A wrong auto-match splits a variety's seed-lot history across duplicate rows,
so the service NEVER auto-creates. matchPlants surfaces RANKED candidates
(exact name → variety-in-name → same species, conservative and name-based),
the user confirms, and CreateFromPacket makes the plant (new or existing) + the
lot. Exactly one of plantId/newPlant, refused otherwise.
- Plants/lots aren't in the undo history (catalog/inventory), so no change set.
- The extractor is injectable (service.WithPacketExtractor) so ExtractSeedPacket
and the /scan endpoint test end to end against a fake, no live model.
Endpoints: POST /seed-lots/scan (multipart image → proposal, reads only; extends
the read deadline for a slow phone upload, caps the body, maps too-large/unreadable
to clear statuses) and POST /seed-lots/from-packet (confirmed proposal → 201).
Docs: README (PANSY_VISION_MODEL), DESIGN (routes + the decision and why the
model can't touch the garden).

Closes#84 (scoped first slice). Objects are focusable role=button with an
aria-label and Enter/Space selection — which makes the existing arrow-key nudge
reachable by keyboard for the first time — with a :focus-visible ring. The
<svg> gets role=application + label + title. Modal traps Tab (robustly: pulls
back focus fallen to <body> when a control is removed/disabled) and restores
focus to the opener if it's still in the DOM. Verified live with real keyboard.
Gadfly round addressed (canonical kind label, aria-current, trap robustness).
- Object aria-label uses kindDef().label (the canonical "In-ground") instead of
an ad-hoc kind.replace() that produced "in ground" and diverged from the UI.
4+ models flagged this.
- aria-current, not aria-pressed, for the selected object — selection isn't a
toggle, which is what aria-pressed means; aria-current marks the active item.
- Modal focus trap made robust: if focus is NOT inside the dialog (fell to
<body> because the focused control was removed — ShareGardenModal's
remove-share button — or disabled while busy, or externally stolen), Tab now
pulls it back in instead of escaping. The previous branches only handled
focus being exactly at a known boundary.
- Focus restore checks opener.isConnected before calling focus(): the delete/
clear flows this targets often remove the element that opened the dialog, and
a disconnected node's focus() silently no-ops.
- Hoisted the focusable-element selector to a module constant, and excluded
input[type="hidden"] (it matched input:not([disabled]) and, at a boundary,
broke the wrap).

Closes#80. internal/imagenorm.Normalize decodes jpeg/png/heic/webp and
re-encodes JPEG, so the seed-packet path (and majordomo's vision) only ever see
a format they can read — HEIC (iPhone default) included. CGO stays off: heic via
libheif-as-WASM, webp pure Go. Hostile-upload bounds: byte cap, overflow-safe
pre-decode pixel/dimension guard, and a recover around the third-party decoders.
The ~5 MB only links in when #81 imports it. Gadfly's blocking round addressed
(panic recovery, the untested pixel-bomb guard now tested, sentinel errors,
lowered pixel cap); EXIF orientation deferred to the #81 handler.
Security / correctness (multi-model):
- Wrap the decoders in a recover (decodeSafely): a malformed HEIC/WebP that
panics libheif-via-WASM or x/image/webp now fails this one request as
ErrUnsupported instead of taking the process down.
- Make the pixel-bomb guard overflow-safe: check each side against maxDimension
BEFORE multiplying, so a header claiming ~2^32 on a side can't wrap
int64(w)*int64(h) negative and slip past the pixel-count cap.
- Lower maxDecodePixels 100 MP → 50 MP (~200 MB peak), still above any current
phone sensor, capping the amplification a small hostile header can force.
- Sentinel errors use errors.New, not fmt.Errorf without a verb.
The finding 5 models agreed on: the decompression-bomb guard was UNTESTED and a
stale comment implied otherwise. Added TestNormalizeRejectsPixelBomb, which
crafts a ~40-byte PNG (valid IHDR + CRC) claiming a huge canvas and asserts
ErrTooLarge from DecodeConfig alone, before any bitmap is allocated — covering
both the per-side and the area trip. Fixed the stale comment.
Error-handling / docs:
- format is now "" on ALL error paths (was populated on some, empty on others).
- Doc rewritten to state the actual error contract (read/encode I/O → wrapped,
not a sentinel) and to stop referencing a non-existent TestNormalize / TODO.
- Guard io.LimitReader's +1 against an int64 overflow at an absurd MaxBytes.
Tests / provenance:
- Downscale test derives its numbers from DefaultMaxDim instead of hard-coding.
- Check the previously-ignored DecodeConfig error in the small-image case.
- testdata/README documents where sample.heic/webp came from.
Deferred to the #81 upload handler, documented in the Normalize doc: EXIF
orientation (best fixed and tested with a real oriented photo end-to-end) and
context cancellation (image.Decode isn't cancellable mid-decode; the caller
runs it under a timeout, and the size guards keep the work finite regardless).

The arrow-key nudge handler existed but only ever acted on a POINTER
selection, and nothing could select without a mouse — so the feature was
unusable by exactly the keyboard users it's for. This is the scoped first
slice: give the canvas a keyboard path in, and fix the Modal focus trap that
every destructive confirmation goes through.
Canvas:
- The <svg> gets role="application" + an aria-label describing the controls,
and a <title> naming the garden — a screen reader now announces an
interactive canvas rather than an empty graphic.
- Each object <g> is a focusable role="button" with an aria-label (name +
kind) and aria-pressed reflecting selection. Enter/Space selects it — the
step that was missing — which makes the existing arrow-key nudge reachable.
- A :focus-visible CSS rule draws a dashed accent ring on keyboard focus (and
NOT on a mouse click, which is the point of :focus-visible). CSS rather than
React state because onFocus on an SVG <g> is unreliable, and a CSS rule
cleanly overrides the shape's inline stroke.
Modal (blast radius: DeleteGarden/ClearBed/DeletePlant/DeleteSeedLot/Share):
- Tab is trapped inside the dialog and wraps at the ends, instead of walking
out into the page behind the backdrop.
- On close, focus returns to the element that opened the dialog rather than
landing on <body>.
Verified live against the built binary with real keyboard input: Tab focuses
an object (SVG <g tabindex> genuinely takes focus), Enter flips aria-pressed
false→true, the focus-visible dash renders (computed stroke-dasharray "5px,
4px"), the dialog traps focus through 5 Tabs, and Escape closes it and
restores focus to the opener.
Follow-ups noted, not done here: object dimensions in the aria-label (needs the
garden's unit context this component doesn't hold), roving-tabindex between
plops inside a focused bed, and the EditorRail tablist semantics.

Prerequisite for seed-packet capture (#81). majordomo's media pipeline is
stdlib-based and cannot decode HEIC or webp — and HEIC is the iPhone camera
default, so the capture feature's very first input would fail on the device
that motivates it. Normalizing at the upload boundary means everything
downstream only ever sees JPEG.
internal/imagenorm.Normalize(reader, opts) decodes any of jpeg/png/heic/webp,
downscales to fit MaxDim (2048, ollama-cloud's limit) on the longest edge with
Catmull-Rom (sharp on the text a packet is mostly made of), and re-encodes JPEG.
CGO stays off: github.com/gen2brain/heic runs libheif as WASM via wazero (pure
Go), golang.org/x/image/webp is pure Go. Both register with image.Decode. The
~5 MB these add only links into the binary when #81 imports this package — it's
not pulled into cmd/pansy yet, so main is unchanged in size for now.
Guards against hostile uploads: input capped at MaxBytes (ErrTooLarge) before a
full read, and the decoded pixel count checked from DecodeConfig BEFORE the
bitmap is allocated, so a small file claiming a huge canvas (a decompression
bomb) is refused up front.
TestNormalizeAllFormats round-trips all four formats to a valid JPEG — its real
job is catching a dropped blank import, where the intuition-breaking failure is
that the COMMON format (png) breaks while the exotic one (heic) still works.
heic/webp fixtures live in testdata (Go has no encoder for them); the webp is a
known-good 16x16 from Python's stdlib test corpus, verified to decode.

Closes#79. Agent model + on/off move into an admin-only Settings section, and
is_admin is enforced for the first time. The live Runner is hot-swapped behind an
atomic.Pointer with routes always registered, so a settings change takes effect
with no restart; /capabilities reads the pointer. Secrets stay in the env, never
the DB. Precedence: Settings → env → default. Verified live: swap on/off/model,
bad spec → 400, race-clean. Gadfly blocking round addressed (dead code removed,
error-swallowing fixed, frontend 503 handling, holder dedup).
Closes#82. Bed filling now exists without an LLM configured, and clear-bed is
ONE change set instead of one per plop (a 40-plop bed no longer needs 40 undos).
POST /objects/:id/fill (region by compass name or rect, degenerate rect → 400)
and /clear, thin adapters over the service methods the agent already uses. Also
fixed DESIGN.md's API block, which had dropped the unauthenticated public route.
Closes#83 (seed-lots half). The only handler file without a sibling API test —
the exact state the journal routes shipped unreachable in. Full CRUD through the
router, derived-remaining (incl. negative/over-planted), private-to-owner ACL
(404 not 403), and requireAuth. Verified the tests catch an unregistered route.
- Remove config.AgentConfig.Ready() — dead after the refactor (no non-test
callers), and its doc comment ("route registration and capabilities gate on
this") was now false. EffectiveAgent.Ready() carries the same logic and IS
used, see below.
- agentHolder now uses eff.Ready() and eff.APIKey instead of an inline check and
a redundant apiKey field it held separately. This makes EffectiveAgent.APIKey/
Ready() production-used rather than test-only, drops the duplicated readiness
check, and simplifies newAgentHolder's signature.
- settingsPayload no longer swallows an EffectiveAgent error into a misleading
empty "effective" view (which would read as "nothing configured"). It returns
the error; the handlers surface it as a 500. EffectiveAgent re-reads the row
GetInstanceSettings just returned, so a failure there is a real DB fault.
- Frontend streamChat handles 503 (assistant disabled at runtime) distinctly
from 404 (endpoint absent) — the backend returns 503 AGENT_DISABLED now, which
the old code mislabelled.
- Fixed the api.go comment that still said a disabled request gets a 404 — it's
a 503.
- updateSettings uses the shared parseNullable[bool] instead of a bespoke
parseNullableBool (now removed).
- NewRunner drops its empty-spec guard; agentmodel.Resolve already owns that
check, so one place decides what a valid spec is.
- rebuild-on-resolve-error now documents WHY it keeps the current Runner rather
than tearing down a working assistant on a transient DB blip: the state is
persisted, the next rebuild reconciles, and killing a live assistant on a read
hiccup is worse than a brief stale window.
Not changed: the store's version-conflict fallback returning GetInstanceSettings'
error instead of ErrVersionConflict when that read also fails. That's the exact
pattern every other version-guarded update uses (gardens/objects/plants); making
only this one differ would be the inconsistency. A DB read failing immediately
after the guarded UPDATE on the same local SQLite file is a disk-fault edge case,
and surfacing that error is defensible.

Closes#78. The 30s server WriteTimeout is an absolute deadline that was cutting
every agent turn over 30s mid-stream — and the keep-alive from #73 could never
work because it ticked into a connection destroyed at 30s. Refresh a per-write
deadline instead: unbounded stream, bounded writes, so a stuck reader still can't
pin the run goroutine. Two client-side regression tests, one per failure mode.
Gadfly: no material issues on final review.
Gadfly re-review: the regression test proved the stream outlives the server
WriteTimeout, but its whole run was under a second — far below the 30s
sseWriteTimeout — so it could NOT tell a per-frame refresh from a deadline set
once at open. A revert to set-once would reintroduce the unbounded-block risk
the per-frame refresh exists to prevent, and sail through the test.
Make sseWriteTimeout a var (production never reassigns it) so a test can shrink
it, and split into two focused cases sharing a streamFrames helper:
- TestEventStreamOutlivesServerWriteTimeout — server WriteTimeout 300ms, frames
straddling it, sseWriteTimeout left at 30s. Catches #78 (no deadline
management → server cuts the stream). Huge margin, so CI slowness only makes
it pass more surely — addresses the "timing margin tight" finding too.
- TestEventStreamRefreshesDeadlinePerFrame — sseWriteTimeout shrunk to 400ms,
8 frames at a 100ms tick (800ms total, 4× margin per gap). A per-frame refresh
delivers all 8; a set-once deadline expires mid-stream and cuts it.
Verified each fails against its own regression: removing the per-write refresh
gives 3/8 on the per-frame test (EOF at ~400ms); removing both deadline calls
gives 0/3 on the outlives test. Both pass on the real code, 3× under -count.
The "clear the deadline entirely" finding was already addressed by the previous
commit (per-frame refresh); this covers it against reintroduction.

- Cover the plantId filter's out-of-range branch (0, -1), not just the
non-numeric one — the handler rejects id < 1.
- Add the documented negative-remaining case: over-planting a lot (57 against
50 bought) drives remaining to -7 through the HTTP surface. The number is a
derived truth about what's committed, not a floor at zero, and that's the
signal a gardener wants.
- Rename objID → oid in the remaining test to match the package convention
(shares_test etc.).
Not taken: relocating createPlantAPI to plants_test.go — it's shared with #89's
branch and the move is cleanest once both land (consolidating with that branch's
makeFillPlant), noted on both PRs. The 409 "current" assertion style is
deliberate and reads clearly; matching journal_test.go's exact phrasing isn't
worth a divergence churn.

- Reject a degenerate (zero-area or inverted) fill rect with 400 instead of
silently planting a single plop at the object centre. An empty `"rect": {}`
decodes to all-zeros and is caught the same way. New fillRect.degenerate()
and a table test covering {}, zero-width, zero-height, and inverted.
- Make the rect a named type (fillRect) rather than an anonymous inline struct,
matching the rest of internal/api, and bind the pointer to a local in the
handler so the deref is visibly guarded rather than reading req.Rect.MinX
under an invariant from a line above.
- ops_test: drop gid from the unpack instead of the `_ = gid` shim.
- ClearBedModal: drop the `const n = plopCount` no-op alias.
Not taken: moving createPlantAPI/makeFillPlant to a shared helper — that
consolidation spans this branch and #88 and is cleanest once both land, as
noted in the PR. Reusing an objectPlantingsPath helper: there isn't one in this
package, and the one inline use doesn't earn a new helper on its own.

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`.

Gadfly, security lens: clearing the write deadline outright traded the
truncation bug for an unbounded one. With no deadline, a client that stops
reading fills the socket buffer and blocks Write forever — pinning the agent
run goroutine and this stream's mutex, which also takes down the keep-alive
since it needs the same lock. The old 30s WriteTimeout at least bounded that.
Refresh the deadline per frame instead: the stream as a whole is unbounded,
but no single write is. That is the only shape that satisfies both ends, since
an absolute deadline cuts long turns and no deadline cannot be recovered from.
The probe stays in openEventStream so a writer that cannot take deadlines is
reported once rather than once per frame; the per-write call deliberately
ignores its error for the same reason.
Also widened the test's timing margins, per the second finding. tick is now
GREATER than writeTimeout, so every frame lands after the deadline has already
expired and the margin only ever grows — a loaded CI runner pushes this toward
passing rather than toward flaking. Sized the other way it would flake exactly
when CI is busiest. Passes 3/3 with -count=3.

FillRegion and ClearObject were reachable only through the agent toolbox, so
on an instance with no model configured the most valuable bulk operation in a
garden planner — and the one carrying the most carefully reasoned geometry in
the codebase — did not exist at all. internal/service/ops.go said these lived
on *Service so "any future REST surface" would inherit the ACL checks; this is
that surface.
POST /objects/:id/fill takes a region EITHER by compass name ("all", "ne",
"south half") or as an explicit rect in the object's local frame, and refuses
both-or-neither: silently preferring one would make a client bug look like a
geometry bug. It answers 200 rather than 201 because a fill can legitimately
create nothing (the region is already planted) and there is no single resource
to point a Location at.
POST /objects/:id/clear replaces a client-side loop of PATCHes. That loop
wrote one change set per plop, so clearing a 40-plop bed took 40 presses of
Undo to put back — while the agent's clear_object, for the identical
user-facing action, undid in one click. CLAUDE.md states the rule it violated:
multi-row operations record together so they undo as one unit. Moving it
server-side also removes the partial-failure case the loop had to reconcile.
TestClearObjectIsOneChangeSetAPI pins that: fill a bed, count change sets,
clear it, assert the count rose by exactly one.
DESIGN.md's API block gains the two new routes, and the four it was already
missing: GET/POST/DELETE /gardens/:id/share-link and the unauthenticated
GET /public/gardens/:token. An unauthenticated surface absent from the
architecture doc is the one worth fixing on sight.

Every other handler file had a sibling API test; this group had none, which is
the state PATCH/DELETE /journal/:id shipped in — implemented, unit-tested
through the service, and completely unreachable. Service tests cannot see a
route that was never registered or one registered with the wrong :param.
Four tests, covering what a broken route would silently take with it:
- Full CRUD over HTTP, including GET/PATCH/DELETE by id, the ?plantId= filter,
a rejected non-numeric plantId, and a stale-version 409 carrying the current
row so the client can rebase.
- `remaining` is derived through the HTTP surface, not just in the service.
DESIGN.md makes derivation load-bearing, and the number is the whole reason
anyone opens the seed shelf.
- Lots are private to the buyer: another user gets 404 (not 403 — existence is
masked per the project convention) on get/patch/delete, sees none in their
listing, and the owner still has access afterwards.
- The group is behind requireAuth: unauthenticated calls 401 rather than
returning an empty list.
Verified the tests actually catch the failure they exist for by unregistering
GET /seed-lots/:id — all four fail with "404 page not found", the journal
signature.

http.Server.WriteTimeout is an ABSOLUTE deadline from when the request header
was read, not an idle timeout. pansy sets it to 30s (cmd/pansy/main.go:65)
while an agent turn is budgeted 4 minutes, so every turn over 30 seconds was
cut mid-stream. The 4-minute runTimeout was unreachable; the real ceiling was
30 seconds.
That also meant the keep-alive added in #73 could never do its job. It ticks
at 20s, so it got exactly one tick before the connection it was pacing was
destroyed underneath it — a mechanism built to survive long silences that was
structurally incapable of surviving them.
The failure is invisible from the handler: writes made after the deadline
return err == nil and their bytes are discarded. There is no error to check
and none to log, which is why this survived a review that specifically looked
at the discarded write error. Only the client sees it, as an unexpected EOF,
which web/src/lib/agent.ts reports as "The connection dropped partway
through." — indistinguishable from a real network fault.
Because it is invisible server-side, the test drives a real http.Server with a
short WriteTimeout and asserts from the CLIENT side. Against the unfixed code
it gets 1 of 4 frames and an unexpected EOF; a test that inspected the return
of io.WriteString would have passed against the bug.
gin 1.10.1's responseWriter implements Unwrap, so ResponseController reaches
the underlying conn. A failure to clear the deadline IS worth logging: it
means the stream will be cut and we cannot prevent it.

Closes#75.
The outer row of a fill sat 1.5 spacings from the bed edge where the rule says
half a spacing, staggered rows started a full pitch in, and the far edge had
clumps hanging 13cm outside a bed nothing clips them to. Centre the lattice and
inset each edge by radius - spacing/2.
Also fixed here: a region that misses the object entirely planted plops metres
off the bed (clampTo inverts rather than empties, which the old loop handled
implicitly and the counted lattice did not), non-finite region bounds now give
ErrInvalidInput instead of a raw store error or a silent no-op, and the lattice
size is derived before it is built so an oversized fill is refused without
allocating what it is rejecting.
Five Gadfly rounds; the substantive findings were the finiteness guard and the
allocate-before-cap ordering.
- 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.

- Split hexCenters' doc: the count/limit contract had run straight on from
the #75 anti-regression paragraph with no separator, so its opening "It"
read as referring to the wrong thing.
- Write the stagger as pitch/2 rather than radius. Same value, but the intent
is "half a pitch" and only incidentally "one radius".
- fitAxis's step<=0 guard is unreachable from its only caller. Kept, and now
says so: a helper this small shouldn't need its caller read to be shown
safe, and the failure mode without it is ±Inf into an int conversion.

- hexCenters now derives its exact point count BEFORE building anything and
returns it alongside the points, refusing over the cap without allocating.
Previously it materialised the whole lattice and fillLoaded checked len()
afterwards — so the "too large" path paid for the thing it was rejecting.
This also makes the preallocation exact, which subsumes the earlier
over-allocation finding I'd declined: staggered rows hold cols-1, so
rows*cols over-reserved by ~12%.
- Region.empty() names the invariant that clampTo expresses "no overlap" by
INVERTING the region rather than zeroing it. A bare `MaxX < MinX` at each
call site was spreading a non-obvious convention across three functions.
The count is now load-bearing (it gates the cap), so the test asserts it
matches what actually gets built.

- FillRegion's doc still said "half-pitch inset", left over from the first
draft of the fix; the inset is radius - spacing/2. Two docs on the same
function disagreeing is worse than either being terse.
- Reject non-finite region bounds. They survive clamping and the inverted-
region guard (NaN compares false both ways). Nothing corrupt reached the
table — SQLite stores NaN as NULL and NOT NULL refuses it — but NaN
surfaced as a raw store error and +Inf as a silent zero-plop success.
- TestHexCentersTinyRegion used a region symmetric about the origin, so it
could not distinguish "the middle of the region" from "the origin" and
would have passed for an implementation that just returned (0,0). Added an
off-centre case.
Not taken: the finding that `make(..., rows*cols)` over-allocates ~12%
because staggered rows hold cols-1. True, but the slice is capped at
maxFillPlops (5000) and the exact count needs a ceil/floor split for no
measurable gain.

- clampTo's doc justified itself by stopping hexCenters "looping forever",
which stopped being true when hexCenters became count-bounded. Say what it
actually does now, and note the inversion the new guard relies on.
- Trim the changelog prose from hexCenters' doc down to the one line that
earns its keep: don't re-anchor at the min corner, and why.
- Rename a test local from `max` so it stops shadowing the builtin.

clampTo INVERTS a region lying wholly outside the object — Max clamps below
Min — rather than emptying it. The old loop-until-past-MaxX form handled that
for free by never entering the loop. Counting positions up front does not:
a region 500cm east of a bed with ±50cm local bounds produced 4 plops at
x=275, a couple of metres off the bed.
Caught by removing the guard and watching the new test fail, not by assuming
it would.

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.

The history write's context.WithoutCancel reads like a mistake if you don't know
why it's there, and "tidying" it is exactly how the orphan-history bug came back
a second time (#73). Written down so the next person — or the next session —
doesn't remove it on the way past.
Also a short testing section. Two of the three bugs only real use found were
invisible to the tests I had: a route that was never registered (service tests
can't see that) and a fixture that populated a field the real response leaves
empty (a test asserting my mental model rather than the API).

README's config table gained OLLAMA_CLOUD_API_KEY and PANSY_AGENT_MODEL, marked
as read once the assistant lands (#56) so the table describes what the binary
does rather than what it will do. Both are already set in Komodo.
Also fixed the Compose example, which still said "# PANSY_OIDC_ISSUER: ... once
auth (#5) lands" — auth landed a long time ago. That is exactly the kind of rot
this commit is trying to prevent, so it seemed worth fixing in the same breath:
the snippet now shows the OIDC vars people actually need to set.
CLAUDE.md now carries the rule explicitly. README updates go in the SAME commit
as the change that needs them — the env var table and the compose snippet are
the two things people copy, so they hurt most when stale. DESIGN.md tracks real
architecture changes. Examples must run. And when you touch a file, check the
comments around your change are still true, because a stale comment is worse
than none: the next reader believes it.

pansy is written by an LLM with a human directing. That belongs near the top of
the README, not in a footnote — someone deciding whether to self-host this and
point it at their own data should know before they decide, not after. The
disclosure says what it actually means in practice (less scrutiny than a
hand-written project, read the code, back up the database) rather than a vague
"AI-assisted" hedge.
CLAUDE.md collects the operational details that otherwise get rediscovered every
session: GOWORK=off, the store/service/api seam and why rules go in the middle
layer, the two unit scales, version-guarded writes, ErrNotFound-as-existence-mask,
the branch/Gadfly/merge/deploy loop, and the env var names that aren't guessable.
It also makes the disclosure a standing rule: if the README is ever rewritten,
that section survives the rewrite, and the only acceptable edit is a clearer one.
