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.
