Gadfly: I was wrong that no plantings-path helper existed — objectPlantingsPath
is defined in plantings_test.go in the same package. Use it for the two
planting POSTs in the remaining test.

- 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.

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.

Closes#44. Two independent grids (garden + per-bed), each with a size and a snap toggle; snapping defaults off. See PR #45 for details.

Per-garden public read-only link: unauthenticated GET /api/v1/public/gardens/:token (no requireAuth, no OIDC), owner-only enable/rotate/disable, and a /g/$token page rendering GardenCanvas read-only. Review fixes: redact plant owner ids, Cache-Control: no-store, 400 on malformed body, shared resetTransient store action.
Closes#41.

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.

Garden objects (beds, bags, containers, in-ground, trees, paths,
structures) in one polymorphic table, following the #7 service
conventions.
- store/objects.go: scanObject + Create (RETURNING), Get, ListForGarden
(z_index order), version-guarded Update (RETURNING, returns current row
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
JSON props, name/notes caps; normalizes rotation to [0,360). Plantable
defaults by kind, overridable.
- api/objects.go: POST /gardens/:id/objects, PATCH/DELETE /objects/:id,
GET /gardens/:id/full ({garden,objects,plantings,plants}). props is any
JSON value stored as text; PATCH is partial + required version, 409
returns the current row.
Tests: service (defaults, plantable-by-kind, rotation normalize,
validation rejects incl. off-field/polygon/bad-color/bad-props, partial
patch + version conflict, cross-user ErrNotFound, delete, /full shape) and
api (CRUD + /full, 409 envelope, cross-user 404, polygon/no-kind 400,
props round-trip).

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).
- CreateGarden uses INSERT ... RETURNING (one round-trip).
- ListGardensForOwner has a defensive LIMIT (pagination is post-v1).
Tests: name/notes length, NaN/Inf/subnormal dims, dimension-at-cap valid,
negative/zero version -> 400.

Establishes the patterns every later backend issue copies: the actor
parameter, centralized role checks, and the version-guard/409 sync
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.
