Introduce pre-computed daily usage rollups from sandbox_metrics_snapshots.
An hourly background worker aggregates completed days, while today's
usage is computed live from snapshots at query time for freshness.
Backend: new daily_usage table, rollup worker, UsageService, and
GET /v1/capsules/usage endpoint with date range filtering (up to 92 days).
Frontend: replace Usage page placeholder with bar charts (Chart.js),
summary total cards, and preset/custom date range controls.
Both control plane and host agent now write structured slog output to
$WRENN_DIR/logs/ in addition to stderr. Log level is configurable via
LOG_LEVEL env var (default: info). SIGHUP reopens the log file so
logrotate can rotate without copytruncate.
Adds self-service endpoints: GET/PATCH/DELETE /v1/me, POST /v1/me/password,
POST /v1/me/password/reset{/confirm}, GET/DELETE /v1/me/providers/{provider}.
Includes OAuth account-linking flow via cookie, hard-delete cleanup goroutine
(24h ticker, 15-day grace period), and OpenAPI spec for all new routes.
Introduce internal/email package with SMTP sending, embedded HTML/text
templates, and multipart MIME assembly. Emails use a generic EmailData
struct (recipient name, message, optional button, optional closing) so
new email types can be added without code changes.
Wired into signup (welcome email), team creation, and team member
addition. No-op mailer when SMTP_HOST is not configured.
Moves 12 packages from internal/ to pkg/ (config, id, validate, events, db,
auth, lifecycle, scheduler, channels, audit, service) so they can be imported
by the enterprise repo as a Go module dependency.
Introduces pkg/cpextension (shared Extension interface + ServerContext) and
pkg/cpserver (Run() entrypoint with functional options) so the enterprise
main.go can call cpserver.Run(cpserver.WithExtensions(...)) without duplicating
the 20-step server bootstrap. Adds db/migrations/embed.go for go:embed access
to OSS SQL migrations from the enterprise module.
cmd/control-plane/main.go is reduced to a 10-line wrapper around cpserver.Run.
