The worst finding is one I created two commits ago: the server's `warning` field
— added precisely because a failed save was being swallowed — was never read by
the client. The "I couldn't save this exchange" message went nowhere, which
recreated the exact silence the warning existed to break. It's wired now, and
SSE frames are validated with zod rather than type-asserted, so the next field
added server-side fails loudly instead of vanishing.
Aborting during the initial fetch reported "Could not reach the server." The
read loop already knew an abort was the caller's own doing; the request path did
not, so pressing Stop looked like the network had failed.
Unmount no longer aborts an in-flight turn, and that one is a design bug of my
own making: selecting an object auto-switches the rail to the inspector, so
clicking the canvas mid-turn silently killed the turn — while the canvas is
exactly what you're meant to be watching. The request continues, the exchange is
persisted server-side, and coming back to the tab shows it. Stop still aborts,
but only our READ: the turn keeps running server-side either way, which is why
its work still lands in History.
/capabilities reported cfg.Agent.Ready() while the routes require NewRunner to
have succeeded. A configured-but-unresolvable model would therefore advertise a
chat tab whose first message 404s. It reports the runner's actual state now, and
is a named handler like everything else in that file.
A failed history load rendered as an empty conversation, which looks like the
thread was lost — a much worse thing to believe than "it didn't load". Both the
loading and error states are shown, and a failed "Start over" says so.
Per-step refresh refetched the change history and the conversation, neither of
which can move until the turn commits: up to 2×(N−1) requests per turn for data
that cannot have changed. Split into a canvas-only refresh for steps and a full
one for the end.
describeUndo had its own copy of totalChanges' summation; it uses the helper,
which now accepts an optional counts list. React.ReactNode became an imported
ReactNode, matching every other component.

The conversational surface, in the editor rather than on its own page. The
reason is the feedback loop: watching the canvas change as the agent works IS
the confirmation, which is exactly what makes "act freely without asking first"
tolerable. It also means the agent never has to guess which garden you mean.
Tool calls surface as they happen, in the app's own vocabulary — "Clearing a
bed", "Looking up a plant" — not raw tool names or JSON. That is the difference
between the panel feeling like it's doing something and feeling like it's hung,
which matters because a replant makes a dozen calls over tens of seconds. An
unknown tool degrades to readable words rather than showing snake_case at the
user, so the client can lag the server by a tool without looking broken.
The canvas refreshes as each step lands, not just at the end. Refreshing only on
completion would put the whole point of siting the chat here — watching it work
— behind the same wait that streaming exists to remove.
Undo sits on the turn itself, so the common case never involves opening the
History panel. It uses #49's useUndo, not a second implementation, which meant
giving that hook an UndoTarget: the chat knows a turn's change set id but not
its tally, and fabricating counts to satisfy the type would have produced a
confidently wrong "1 of 1 changes undone". describeUndo now says "Partly undone"
when it has no denominator rather than inventing one.
The panel is only offered when the instance actually has the assistant
configured, via a new /capabilities read. The routes 404 without a key, so
without this the client would have to probe for a 404 to find out — and a tab
that opens onto an apology is worse than no tab.
Streaming is hand-rolled over fetch rather than EventSource, which can only
issue GETs and this needs a POST body. The wire format is still SSE, so a proxy
that understands it doesn't buffer and the server wouldn't change if EventSource
became viable. Partial frames are buffered across chunks and a malformed frame
is skipped rather than killing a working stream.
Errors read as sentences, and as different sentences: a permission refusal, a
timeout and a model failure want different reactions. Every failure path
refreshes, because something may have landed before it failed — and says where
to look for it.

Fixes from the PR #29 adversarial review (considered; not graded).
Performance / correctness
- ObjectShape is memo'd, so a pan/zoom (which only mutates the world <g>
transform) no longer re-renders every object.
- 'circle' objects render as an <ellipse> (rx/ry), honoring both dims — a
circle when width == height — instead of ignoring heightCm.
- The 1 m grid now actually fades in (opacity ramps as cells grow past the
visibility threshold), matching its description.
- Unique SVG pattern id (useId) so multiple canvases can't collide.
- The canvas re-fits when the garden id changes (not just once), so #11
switching gardens reframes.
Robustness
- geometry.zoomToFitRect takes rect size by magnitude; wheel/pinch ignore
non-finite deltas; ObjectShape clamps dimensions to >= 0 (no invalid SVG).
Maintainability
- Renamed the Size params from `viewport` to `canvasSize` (4 models); moved
easeInOutCubic/lerp into geometry.ts; renamed toLocal → clientToCanvas;
named constants for the label/corner factors; DEFAULT_FILL const;
EditorGarden.unitPref imports UnitPref; the Fit control uses the shared
Button. focusedObjectId/plantable are intentionally reserved for #11/#15.
tsc + 17 vitest tests green; re-verified in a browser (ellipses render,
unique pattern id, wheel zoom + Fit).

The editor's technically-riskiest slice, built against mock data so #11
only adds interactions on top.
- lib/geometry.ts (+ vitest): world<->screen and object-local<->world
transforms, clampScale, zoomViewportAt (the wheel/pinch "keep the point
under the cursor stationary" math), zoomToFitRect. 11 geometry tests
(round-trips, rotation, cursor-anchored zoom, fit) + 6 units tests.
- editor/store.ts: Zustand store for ephemeral editor state — viewport,
selection, focusedObjectId (selection interactions grow in #11).
- editor/useViewport.ts: @use-gesture wiring — wheel + pinch zoom toward
the pointer, drag-pan, scale clamped to [0.05, 20] px/cm, and an animated
fitToRect (eased rAF tween). touch-action:none so the browser doesn't
fight gestures.
- editor/ObjectShape.tsx: rect/circle centered + rotated, kind default
colors, name label; non-scaling strokes so outlines stay 1px at any zoom.
- editor/GardenCanvas.tsx: full-size svg, single world <g>, fading 1m grid,
garden boundary, z-ordered objects; ResizeObserver-driven auto-fit, a
zoom readout, and a Fit control. Deps: zustand, @use-gesture/react,
vitest (+ test scripts).
- GardenEditorPage renders the canvas with a mock scene (#11 swaps in
/full).
Verified in a real browser: wheel zoom keeps the world point under the
cursor stationary (sub-cm drift on a 12m garden), a real drag pans, and
Fit animates to frame the garden. tsc + vitest green.

Fixes from the PR #27 adversarial review (considered; not graded).
Correctness / error-handling
- Modal: focus once on mount and attach the keydown listener once (latest
onClose/busy via refs), so a parent re-render (e.g. a background refetch)
no longer re-fires focus() and steals it from the input being typed in.
- Modal takes a `busy` prop; while a save/delete is in flight, Escape and
backdrop clicks don't dismiss it (form/delete modals pass busy=pending),
so an action can't be interrupted mid-flight and lose its error.
- Form validates the *converted* centimeter values against the server's
[1cm, 100m] bounds, so sub-cm / over-100m sizes fail client-side with a
clear message instead of a generic server error.
- displayFromCm rounds imperial to 0.1 ft so an 8 ft garden (244 cm)
prefills as "8", not "8.01".
Maintainability
- Extracted ui/field.ts (useFieldId + fieldControlClass) shared by
TextField/TextArea/Select. Added a `danger` Button variant, used by the
delete modal; card edit/delete buttons gained focus-visible rings.
- useUpdateGarden takes the id in its mutation variables (no dummy 0 during
create). GardensPage shares a close handler; dropped a redundant zod
annotation; 409 rebase reuses dimString; renamed `del` -> `deletion`.
Verified in a browser: 8 ft round-trips to a prefilled "8"; a sub-cm value
is rejected client-side with the modal staying open. tsc clean.

The /gardens page is now home base, backed by the #7 API.
- lib/units.ts: cm <-> meters/feet conversion + formatCm/formatDimensions
(metric "m", imperial "ft/in"). Minimal for #8; #9's geometry lib
consolidates.
- lib/gardens.ts: zod gardenSchema + useGardens/useCreateGarden/
useUpdateGarden/useDeleteGarden (mutations invalidate the list) and
conflictGarden() to pull the fresh row out of a 409.
- GardensPage: loading/empty/error states; empty state prompts a first
garden; responsive card grid (single column on phones).
- GardenCard: name, dimensions formatted per the garden's unit, notes
preview; body links into /gardens/:id, edit/delete kept out of the link.
- GardenFormModal: create/edit with a unit selector; dimensions are entered
in the chosen unit and converted to cm (switching units converts the
current values). A 409 rebases the form onto the server's fresh row.
- DeleteGardenModal: confirmation before removing.
- ui/: Modal (Escape/backdrop close), TextArea, Select.
Verified in a real browser against the embedded binary: create appears
without reload; edit persists (version 2), form prefilled from stored cm
converted back to the garden's unit; delete confirms then removes -> empty
state; an imperial 4 ft x 8 ft garden stores 122 x 244 cm and shows
"4' 0" x 8' 0"". tsc --noEmit clean.

Fixes from the PR #25 adversarial review (graded 23 real / 5 false positive):
Error handling
- onLogout wraps mutateAsync in try/catch: a failed logout no longer
becomes an unhandled rejection; the user stays put (session still valid)
and the button offers "Retry sign out" (5 models flagged this).
- Root errorComponent (RouteError): a non-401 /auth/me failure in a
beforeLoad guard now shows a recoverable "Try again" screen instead of
blanking.
- Forms drop noValidate, restoring native required/type=email/minLength
checks before hitting the server.
Correctness
- RegisterPage gates on providers.isPending/isError before rendering, so
the form no longer briefly appears (submittable) on an SSO-only server.
- TextField id falls back to name then a useId() value, so the label/hint
associations hold even if a caller omits both.
Maintainability
- Single safeRedirectPath (lib/redirect.ts) replaces the duplicated
safeRedirect/safeInternalPath (4 models).
- Generic ApiError helpers (apiErrorCode, errorMessage) moved to lib/api.ts;
LoginPage builds the OIDC URL from the exported API_BASE.
- Divider moved to components/ui/. errorMessage doc clarified.
Verified again in a real browser: register -> /gardens; Sign out -> /login.
tsc --noEmit and vite build clean.
Not changed (graded, with rationale): OIDC deep-link redirect isn't
preserved (needs backend state threading — follow-up); 60s me staleTime in
guards (server is authoritative); the login/register onSubmit catches are
the intended react-query pattern (errors render via mutation state).

Frontend for pansy auth, rendering whatever /auth/providers reports.
- lib/auth.ts: zod-validated User/Providers, a shared meQueryOptions
(a 401 resolves to null, not an error) reused by useMe() and the router
guard, useProviders(), and useLogin/useRegister/useLogout mutations that
prime/clear the me cache (logout also drops non-auth cached data).
- lib/queryClient.ts: one QueryClient shared by the React tree and the
router context so guard and components hit the same cache.
- router.tsx: createRootRouteWithContext with the queryClient; requireAuth
(redirects to /login?redirect=<dest>) on gardens/plants/editor, and
requireGuest on login/register (bounces authed users away). Login search
params (redirect, error) validated as optional; redirect targets are
restricted to same-origin paths.
- pages/LoginPage: OIDC button (label from providers) linking to
/auth/oidc/login, "or" divider, local email/password form, and friendly
messages for the OIDC callback ?error= codes. RegisterPage: email +
display name + password (min 8), registration-closed and SSO-only
handling; auto-login lands on /gardens.
- AppShell: auth-aware nav — shows the user's display name + Sign out when
logged in, Sign in otherwise; nav links only when authed.
- ui/: TextField (16px text to avoid iOS zoom, autocomplete + a11y),
Button (+ shared buttonClasses for the OIDC anchor), Alert; AuthCard.
Verified in a real browser against the embedded binary: register →
auto-login → /gardens; refresh stays in; Sign out → /login; a logged-out
/gardens/1 redirects to /login and returns after login; OIDC button renders
with the Authentik label when configured. tsc --noEmit clean.

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.
