Twenty-one prompts against the live assistant found one fabricated success,
a model that believed it was 2025, and a describe_garden that was ~450 plop
entries per turn. This is the set of fixes, each traceable to a finding:
- The gardener's LOCAL day travels with the turn (`today` on POST /agent/chat,
sent by the UI like plantedAt) into the system prompt and every dated tool
default. Left to guess, the model dated journal entries a year back; left to
the server, a 9 pm fill landed on UTC's tomorrow.
- describe_garden groups plops by plant — count, where, planted date, days to
maturity — and lists ids only for groups of ≤ 8; list_plantings spells a big
group out on demand and remove_plantings acts on one plant in a bed ("take
the beets out, leave the garlic"), which used to mean 116 single removals.
- New tools: move_planting (keeps the planting date; across beds via the new
MovePlanting, which is why the store's UPDATE now writes object_id),
update_plant, read_history, copy_garden (the "<garden> — <year>" plan
convention). fill_region takes an explicit local rectangle and a seedLotId;
place_planting's radius defaults to one plant (spacing/2) instead of a guess.
- The system prompt states the date and the gardener's units, forbids claiming
a change no tool made, says it cannot undo and points at the Undo button,
asks before clearing beds on an ambiguous sentence, and stops narrating its
own plantings into the journal.
- A mutation aimed at ANOTHER garden inside a turn is recorded under that
garden as its own change set, not filed into the open scope.
- UI: the thread scrolls inside the Assistant panel so the composer stays
put; every tool has a step label; wide tables stay inside the bubble.

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).

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`.
Docs: README (precedence + key-stays-in-env), DESIGN (decision + routes),
CLAUDE (don't re-add conditional route registration; key never in the DB).

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).

#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.
