Gadfly findings on #95:
- Correctness (3 models): the shared inset formula radius-spacing/2
collapses to 0 in grid mode (radius = spacing/2), so grid's outer row
planted flush on / overhanging the bed edge instead of the half-spacing
in that the rule wants. The inset genuinely differs by layout — a grid
plant sits AT the plop centre (inset spacing/2), a clump's plants reach
its rim (inset radius-spacing/2, overhanging by a half). Split it into a
new edgeInset(radius, spacing, layout); hexCenters now takes a
precomputed inset and is pure geometry (no spacing/layout knowledge).
Regression guard: grid plants land at ±25 on a 60cm bed, not ±30.
- Performance (2 findings): the in-loop `existing = append(existing, *p)`
was dead — every plop in one fill shares a radius and sits on a distinct
lattice point, and a plop is "covered" only when wholly inside another,
impossible between equal-radius circles at different centres. Removing it
stops the coveredByExisting scan growing during the fill (an empty-bed
grid fill's check was needlessly quadratic in the plop count).
- Docs: FillRegion/fillLoaded/hexCenters comments and the DESIGN.md bullets
updated for plopRadiusFor/edgeInset (were still citing defaultPlopRadius
and "written out in hexCenters").
- Test hygiene: split the grid + bad-layout cases out of TestFillAndClearAPI
into TestFillLayoutAPI (one concern per test).
The enum-tag finding is a non-issue: majordomo's DefineTool derives its arg
schema from the same struct-tag reflection as Generate (proven by the vision
SeedPacket enum), and the service validates mode regardless.

Gadfly findings on #94, the real ones:
- scanSeedPacket extends only the READ deadline; a slow upload + a live
vision call runs past the server's absolute 30s WriteTimeout and the
successful response is silently dropped (the #78 failure mode). Extend
the write deadline too (scanWriteTimeout).
- An oversized upload tripping MaxBytesReader was mapped to 400; it's 413.
Detect *http.MaxBytesError and report IMAGE_TOO_LARGE.
- Split imagenorm error mapping: ErrTooLarge->413, ErrUnsupported->400,
genuine read/encode faults (and a failed file.Open)->500, not 400.
- CreateFromPacket discarded the plant it created when the lot then
failed, contradicting its own doc. Roll the new plant back instead so
the confirm is all-or-nothing (a fresh plant has no lots/plantings, so
the delete is safe; log-and-continue on cleanup failure).
- Dedup: packetLotRequest and seedLotCreateRequest shared every lot
field. Extract a seedLotFields base both use. validCategory now reuses
plantCategories. EffectiveConfig resolves agent+vision from one
settings-row read instead of two.
- capabilities swallowed an EffectiveVision error silently; log it.
- vision test hand-copied Extract's body (drift risk). Split generate()
out of Extract so the hermetic test drives the real request builder.
Tests: rollback-on-lot-failure (service), oversized->413 (api).

Steve chose option 3: keep clumps as the default primitive, add a grid/rows
fill mode, so sketching and planning are different operations with different
outputs rather than one model forced to be both.
A plop is a CLUMP, not a plant — great for "a few plops of garlic in a corner",
useless for drawing a plantable 8-rows-of-garlic bed (that came out as ~15
blobs, #77). FillLayout selects what a fill packs:
- clump (default, unchanged): radius 1.5×spacing, ~7 plants per plop.
- grid: radius spacing/2, pitch = spacing, ONE plant per plop — rows you could
actually plant from.
The geometry is the SAME hexCenters lattice and the SAME #75 half-spacing edge
rule; only the radius→spacing relationship differs (plopRadiusFor). Grid keeps
no 15cm floor — its whole point is true spacing — while clump keeps it so a
tiny-spacing plant doesn't make invisible clumps.
Threaded through FillRegion/FillNamedRegion (empty layout = clump, so existing
callers are unchanged; unknown layout = ErrInvalidInput), the REST /fill
endpoint (`layout`), and the agent's fill_region tool (`mode`, enum clump|grid),
so "plant the bed in rows" works.
Tests: grid produces many more, single-plant plops than clump on the same bed
(radius spacing/2, derived count 1); unknown layout is refused at both the
service and the API. maxFillPlops still caps a grid fill of a huge bed.
No frontend fill affordance exists yet (fill is agent-only in the UI; the fill
UI was deferred in #82), so the mode toggle rides along when that's built —
noted. Docs: DESIGN placement-model decision.

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#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.

planting POSTs in the remaining test.

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.

Fixes from the PR #28 adversarial review (considered; not graded).
Correctness / API
- PATCH /objects/:id can now clear nullable color/props back to NULL: the
request takes them as json.RawMessage, and ObjectPatch carries an explicit
Set flag so an explicit `null` (clear) is distinguished from an absent
field (unchanged) — the strongest cross-model finding (6 hits). New test.
Maintainability
- store/plantings.go + plants.go use explicit qualified column lists
(qualifyColumns helper) instead of SELECT *, matching gardens/objects and
surviving a future column add.
- Consolidated objectKinds + plantableByDefault into one kind→traits map.
- objectForRole factors the fetch-then-authorize shared by UpdateObject and
DeleteObject; dropped the redundant kind check in CreateObject
(finalizeObject is the single validation point).
- Request→service mapping via toInput()/toPatch() methods (matches gardens).
- Renamed handler gardenFull → getGardenFull (verbNoun); test helper
decodeGarden → decodeMap; generic bind-error messages.

on conflict), Delete (plantings cascade via FK).
- store/plantings.go + plants.go: the read side /full needs now —
ListActivePlantingsForGarden (removed_at IS NULL) and
ListReferencedPlants (distinct plants used by active plantings). Both
return empty until #14 adds plantings; #12/#14 extend these files.
- service/objects.go: Create/Update(partial patch)/Delete/GardenFull, all
(ctx, actorID, ...) through requireGardenRole(editor for mutations,
viewer for /full). finalizeObject validates kind + shape (rect/circle;
polygon reserved), finite dims in [1cm,100m], NaN/Inf rejection, loose
bbox-overlaps-garden placement (partial overhang OK), hex color, valid

Fixes from the PR #26 adversarial review (graded 18 real / 0 false positive).
Correctness / security
- maxGardenCM fixed to 10_000 (100 m), matching its comment — it was
100_000 cm (1 km), 10x too lax (5 models flagged this).
- Dimension validation now rejects NaN/Inf (which slip past naive
comparisons) and subnormal-tiny positives, via a finite [1cm, 100m]
check. Name (200) and notes (10_000) are length-capped so untrusted
input can't balloon storage.
- Update version binding is `required,min=1`, so a negative/zero version
is a 400, not a 409.
Maintainability / performance
- One unified writeServiceError (new errors.go) maps every auth + resource
sentinel; writeResourceError removed. writeVersionConflict and
parseIDParam moved to errors.go (shared, not in the gardens feature file).
- Request structs share an embedded gardenFields (one toInput).

protocol. The service layer is the seam both REST handlers and future
agent tools call, so permissions live here, not in handlers.
- service/gardens.go: Service methods take (ctx, actorID, args).
requireGardenRole(ctx, actor, gardenID, min) is THE authorization point
— owner is implicit via owner_id now; #16 extends it to consult
garden_shares. A user with no role gets ErrNotFound (existence masked),
not ErrForbidden. Create/Get/List/Update/Delete with input validation
(name required, 0 dims default to 10 m on create / rejected on update,
negatives always rejected, unit metric|imperial, 100 m cap).
- store/gardens.go: version-guarded UPDATE ... WHERE id=? AND version=?
RETURNING; a no-match re-reads to return (current row,
ErrVersionConflict) vs ErrNotFound. ListGardensForOwner returns a
non-nil slice.
- api/gardens.go: GET,POST /gardens and GET,PATCH,DELETE /gardens/:id
behind requireAuth. writeVersionConflict documents the 409 envelope
({error:{code,message}, current:{...}}) — the contract for every
mutable resource. writeResourceError maps ErrNotFound/Forbidden/
InvalidInput/VersionConflict; parseIDParam guards path ids.
Tests: service (defaults, validation, owned-only list, version
conflict returns current + retry, cross-user ErrNotFound, delete) and
api (full CRUD flow, 409 envelope shape, cross-user 404, auth required,
create validation). Verified against the running binary: create stores
imperial 122x244 cm and list returns it.

Fixes from the PR #24 adversarial review (graded 23 real / 1 false positive):
Security / correctness
- LinkOIDC no longer overwrites a different stored identity: the UPDATE
matches only when the row has no identity yet or already carries this
exact one, so a second IdP asserting the same verified email can't
hijack or lock out an account (returns ErrOIDCIdentityConflict). Uses
a single UPDATE...RETURNING (also fixes the ignored-RowsAffected /
misleading-ErrNotFound path and the round-trip).
- Provisioning now requires a verified email for BOTH linking and JIT
creation (was: linking only), so an unverified-email identity can't
create an account — nor become the first admin on a fresh instance,
nor squat an email a real user later owns.
- OIDC-identity collisions surface as the dedicated ErrOIDCIdentityConflict
instead of the email-specific ErrEmailTaken.
Robustness
- readOIDCTxCookie requires a non-empty nonce (an empty one would make the
callback's nonce check pass vacuously).
- Callback token exchange + verify run under a 15s context timeout so a
slow IdP can't outlast the server write timeout.
- ensure() performs discovery outside the mutex, so concurrent cold-start
requests don't serialize behind one another's full timeout.
- setOIDCTxCookie returns its marshal error; oidcLogin aborts rather than
redirecting to the IdP with no tx cookie.
Maintainability
- redirectAuthError helper dedups the ~dozen callback redirects (and the
empty-code path now logs like the rest).
- Distinct login error codes (no_email / email_unverified / oidc_conflict)
for the UI; writeServiceError maps the OIDC sentinels; shared test issuer
const.
Tests: unverified email refused for both link and JIT; identity-overwrite
refused while the original identity keeps working.

OIDC is pansy's primary login path (Authentik the target IdP); local
auth (#4) remains the fallback and both issue the same session cookie.
- deps: github.com/coreos/go-oidc/v3 + golang.org/x/oauth2 (both pure Go;
CGO stays off).
- api/oidc.go: lazy issuer discovery (retried per-request, never crashes
a server that also serves local auth), GET /auth/oidc/login builds an
authorization-code URL with PKCE S256 + random state + nonce stashed in
a short-lived HttpOnly cookie, GET /auth/oidc/callback verifies state
(constant-time), exchanges the code with the PKCE verifier, verifies the
ID token + nonce, and starts a pansy session. Failures redirect to
/login?error=... ; success to /gardens.
- service.LoginOIDC: (issuer,subject) match -> login; else *verified*
email match -> link onto the existing account; else JIT-create (the IdP
gates access, so PANSY_REGISTRATION doesn't apply). Unverified email
colliding with an existing account is refused (takeover guard); no email
is refused (email is the account key). Reuses the atomic CreateUser.
- store: GetUserByOIDC + LinkOIDC (unique-pair backstop).
- config: OIDCReady() (needs issuer+client+BaseURL for the redirect URI);
/auth/providers now reports oidc from it and defaults the button label
to "Sign in with Authentik". OIDC routes are only registered when ready,
so an unconfigured instance 404s them.
- PANSY_LOCAL_AUTH=false rejects/hides local auth but not OIDC.
Tests: service provisioning (JIT, repeat login, link, unverified-collision
refusal, no-email, name fallback, works with local auth off); api
(routes-absent-when-unconfigured, providers reporting, login redirect with
PKCE params + tx cookie via a fake discovery server, callback state/error
paths). Smoke-tested: unreachable issuer degrades to error=oidc_unavailable
with the server still up and local auth working.

Fixes from the PR #23 adversarial review (graded 35 real / 1 false positive):
Security / correctness
- Race-free registration: is_admin and the registration gate are now
computed atomically inside a single INSERT...SELECT, so concurrent
first registrations can't both become admin or bypass closed
registration (fixed the whole TOCTOU cluster).
- Sliding session now reaches the browser: ResolveSession returns the
current expiry and requireAuth re-sets the cookie, so active users
aren't logged out 30 days after login regardless of activity.
- Login CSRF: csrfGuard rejects state-changing requests whose Origin
doesn't match PANSY_BASE_URL (no-op when unset, so the dev proxy is
unaffected). SameSite=Lax alone didn't cover this.
- argon2id tuned to RFC 9106's second recommended profile (t=3).
- Timing equalizer can't fail open: the dummy hash is derived
deterministically (fixed salt, no RNG) so it's always present.
- Password length (<=1024) enforced in the service for both register
and login, not just HTTP binding tags; login rejects over-long input
before spending argon2 work.
Error handling / robustness
- Login logs a malformed stored hash instead of silently treating it as
a wrong password.
- Best-effort session writes (Touch/Delete during renewal, expiry, and
corrupt-expiry cleanup) now log on failure.
- index sessions.expires_at via new migration 0002 (0001 is immutable).
Maintainability
- Extract startSessionAndRespond and abortUnauthenticated; make
writeServiceError a free function; consistent error handling in
decodeHash; doc/comment fixes.
Tests: over-long password, CSRF guard (cross-origin/same-origin/dev
no-op), and cookie refresh on authenticated requests; migration-version
assertions bumped to 2.

Implements pansy's local (email + password) authentication and the
session layer that OIDC (#5) will also reuse.
- store: users.go (create/get-by-id/get-by-email/count) and sessions.go
(create/get/touch/delete/delete-expired), scanning the existing 0001
schema.
- service: the business-logic seam. auth.go (Register/Login/session
lifecycle/Providers) + password.go (argon2id, 64 MiB/1/4, PHC-encoded,
constant-time verify) + service.go (Service, clock injection, token
hashing). First user is admin; closed registration still allows the
bootstrap user; unknown-email and wrong-password are indistinguishable
(same error, same argon2 work via a dummy hash).
- api: POST /auth/register|login|logout, GET /auth/me|providers, plus a
requireAuth middleware that resolves the HttpOnly session cookie
(SameSite=Lax, Secure under https) to the actor. Handlers stay thin.
- main: wires the service and a periodic expired-session sweep; sessions
are also dropped lazily on access. Sliding 30-day expiry.
- tests: service (register/login/expiry/renewal/cleanup, password) and
api (cookie flow, middleware, validation, providers).
Verified end-to-end via curl: register -> me -> restart -> session
persists -> logout -> 401.

Applied the fixes warranted by the adversarial review of PR #21 (all
findings graded in the gadfly store):
Store (highest impact):
- buildDSN always merges busy_timeout/journal_mode/foreign_keys pragmas
into the DSN, even for file: URIs or paths with a query string — the
prior passthrough silently disabled FK enforcement for those PANSY_DB
values. Also escape '#' in the path and tighten in-memory detection to
an exact ':memory:' token or mode=memory param (no substring misfire).
- migrate.go: detect duplicate migration versions with a clear error;
wrap appliedVersions' rows.Err() with the store: prefix.
API:
- SetTrustedProxies failure now falls back to trust-none instead of
leaving gin's trust-everyone default (X-Forwarded-For spoofing).
- SPA: 404 embedded directories (was a directory listing), 404 bare /api,
add X-Content-Type-Options: nosniff, cache index.html bytes once at
startup, single fs.Stat existence check, shared writeAPIError helper.
- Move gin.SetMode out of package init() into New().
Config: validate PANSY_PORT range (fall back to 8080 with a warning).
Web:
- api.ts: serialize the request body before the fetch try so a
JSON.stringify failure isn't misreported as a network error.
- AppShell: move state-specific/conflicting utilities into
active/inactiveProps so concatenated Tailwind classes don't collide.
Tests: added store DSN-pragma/memory-detection cases and SPA
directory-404 case. go build/vet/test clean (CGO off); web tsc + build
clean; re-verified in a browser (SPA, deep links, /assets 404, nav).

Implements the Pansy v1 scaffold (epic #20, phase 0).
#1 Backend: Go module (pure-Go, builds with CGO_ENABLED=0), env config,
gin server with slog + recovery + /api/v1/healthz, modernc SQLite store
with WAL/busy_timeout/foreign_keys pragmas, embedded numbered-migration
runner, full initial schema (users, sessions, gardens, garden_shares,
garden_objects, plants, plantings), domain structs + sentinel errors,
graceful shutdown.
#2 Frontend: Vite + React 19 + TS (strict) + Tailwind 4 + TanStack
Router/Query, typed /api/v1 fetch wrapper (ApiError carries status +
body so later issues can read 409 conflict rows), dev proxy /api -> :8080,
responsive app shell with stub pages for all five routes.
#3 Single binary: //go:embed of the web build with a committed placeholder,
SPA fallback (deep links, immutable asset caching, JSON 404 for unmatched
/api and missing assets), Makefile (web/build/dev/test), README quickstart
+ env var table.
Verified: go build/vet/test clean (CGO off); binary migrates idempotently and
serves healthz; web tsc + build clean; integrated binary serves the SPA, deep
links, and correct cache headers; app mounts and navigates all five routes at
desktop and 375px widths.
