Remediate the MEDIUM backend correctness/perf findings from the 2026-07-11 audit.
B1 — a group cron template toggled disabled→enabled no longer re-fires every
descendant's cron. Materialization now KEEPS a disabled cron template's copies
(syncing `enabled` in place) instead of delete+recreate, preserving
`last_fired_at`; the scheduler already skips disabled copies, so keeping them is
inert. Queue/email arms still delete-on-disable (freeing the one-consumer slot).
B2 — `rematerialize_stateful_templates` warnings are now logged at the
app-create/delete and group-reparent chokepoints (were silently dropped); only
the `Err` arm was handled before.
B3 — the group KV/docs byte-quota check skips the O(rows) `SUM(octet_length(..))`
scan when a cheap upper bound (`rows_after * max_value_bytes`) is already under
the cap, so the full aggregate only runs near-cap. Every row is validated
≤ max_value_bytes, so the bound is sound (never lets an over-quota write through).
B6 — the in-process SSE broadcaster caps live channels per map
(`PICLOUD_REALTIME_MAX_CHANNELS`, default 100k); a subscribe that would open a
NEW channel past the cap is refused with 503 + `Retry-After: 1` rather than
growing the (app,topic)/(group,topic) maps unboundedly. Check+insert is atomic
under the map mutex (no TOCTOU); an existing-channel subscribe is exempt.

materialize::rematerialize_stateful_templates reconciles a group cron/queue
template into one app-owned copy per descendant (materialized_from = template),
via the all-apps app_chain CTE ⋈ group-owned stateful templates. A precise
create/delete diff preserves cron last_fired_at on unchanged copies; a queue
copy is skipped-with-warning when the app already fills that queue's consumer
slot (the one-consumer invariant). Called full-live at the route-rebuild
chokepoints: apply (single + tree), app create/delete (apps_api), group
reparent (groups_api) — AppsState/GroupsState gain a pool. Pinned by
tests/stateful_templates.rs (per-app copy, idempotent, new-app materializes,
reparent de-materializes).

The runtime half. Group route TEMPLATES now expand into every descendant
app's in-memory match slice, live, with no per-app materialization.
- `compile_effective_routes` consumes the `list_effective` expansion and
applies NEAREST-OWNER-WINS shadowing: for one app, identical binding
tuples (method+host+path) owned at multiple chain levels collapse to the
nearest (an app's own route shadows an ancestor-group template); a nearer
group beats a farther one. Non-identical bindings coexist and the
existing matcher precedence resolves each request. `compile_route` now
takes the effective app_id, so the matcher + dispatch are unchanged.
- `rebuild_route_table` is the single refresh chokepoint (list_effective →
compile_effective_routes → replace_all). Route CRUD, the apply reconcile,
and startup all route through it; the apply guards drop the "a group node
touches no routes" assumption (a group apply may now create templates).
- FULL-LIVE INVALIDATION: app create/delete (apps_api) and group reparent
(groups_api) rebuild the snapshot, so inherited routes take effect the
instant the tree changes — matching the live model of triggers/vars.
Best-effort, mirroring apply: a failed rebuild self-heals on the next
write or restart, never failing the committed mutation.
The isolation boundary is the chain expansion: a template lands only in the
slices of apps whose ancestor chain contains the owning group. Pinned by a
deterministic live-DB integration test (descendant inherits, sibling
subtree does not, app shadows by identical binding, non-identical coexists).

Server-side foundation for Phase-2 groups (no group-owned resources yet):
Shared types:
- GroupId, Group; App gains group_id; AppRole::{precedence,max} for
folding the highest effective role across the membership chain.
Repos:
- group_repo: tree CRUD with reparent (ancestor-walk cycle guard under a
coarse instance-wide structural advisory lock; slug frozen; bumps
structure_version) and delete=RESTRICT (refuses non-empty groups).
- group_members_repo: per-(user, group) role grants, mirroring app_members.
Hierarchy-aware authz (§5.3):
- AuthzRepo gains effective_app_role / effective_group_role (default to
direct membership / none, so the ~18 existing test stubs are untouched);
the Postgres impl resolves each via one depth-bounded recursive CTE that
MAXes the app's own row with every ancestor group_members row.
- can(): the Member path now folds inherited group roles, so a group_admin
on any ancestor is implicitly app_admin beneath it. New Capability
variants InstanceCreateGroup / Group{Read,Write,Admin}; group caps carry
no app_id (bound API keys can't manage groups). 8 new unit tests.
Admin API:
- groups_api: group CRUD + reparent (admin at both source and destination
parent, §5.6) + per-group members, all capability-gated.
- apps: POST /apps takes an optional parent group (default root); app
responses carry group_id; my_role now reflects the effective role.

Aligns the canonical capability rules with how the dashboard now shadows
its UI. Instance admins become implicit app_admin on every app (only
InstanceManageSettings stays owner-only), and the script-delete handler
moves from AppWriteScript to AppAdmin so editors can save but not delete.

apps_api.rs and app_members_api.rs each grew a near-identical local
`resolve_app` that parses an id-or-slug param and translates None into
their own AppNotFound variant. Promote the lookup half to
`app_repo::resolve_app` (returns `Result<Option<AppLookup>, ...>`) and
let callers handle the None → not-found mapping.

GET /api/v1/admin/apps/{id_or_slug} now returns an `AppRole`-typed
`my_role` alongside the existing app fields, computed server-side from
the Principal: `Owner → app_admin` and `Admin → editor` (both
implicit per blueprint §11.6), `Member → app_members.role` (looked up
via the existing `AuthzRepo::membership` already in `AppsState`).
The dashboard uses this single field to decide whether to render
admin-only surfaces (Members tab, etc.) instead of duplicating the
implicit-grant rules on the client side — keeps API and UI gate logic
identical with one round-trip.

Every admin endpoint now resolves Capability for the loaded resource
and calls authz::require(...) before mutating. Forbidden → 403; every
handler State carries an Arc<dyn AuthzRepo>, plumbed from the new
PostgresAppMembersRepository in the picloud binary.
* api.rs (scripts): AppRead/AppWriteScript/AppLogRead bound to
script.app_id after load. List branches on instance_role:
Member → list_for_user, others → list (or ?app= filtered).
* apps_api.rs: InstanceCreateApp on POST; AppRead on get/list_domains;
AppAdmin on patch/delete/slug:check; AppManageDomains on
create_domain/delete_domain. list_apps membership-filters for Member.
* admin_users_api.rs: InstanceManageUsers on every endpoint. Mint +
PATCH refuse to grant Owner unless the caller is already Owner
(CannotEscalate / 422), on top of the existing last-owner guard.
* route_admin.rs: AppRead on list/check/match; AppWriteRoute on
create/delete bound to the route's actual app_id (added a
RouteRepository::get(uuid) lookup so delete binds correctly).
* AppRepository + ScriptRepository gain list_for_user(user_id) for
membership-filtered listings.

Deleting an app used to require zero scripts and zero domain claims —
practical for empty apps, painful for anything else. Add an opt-in
cascade so the operator can wipe an app in one click while keeping the
safe default for the no-flag case.
Backend: `DELETE /api/v1/admin/apps/{id}?force=true` runs a single
transaction that removes every script in the app (routes and execution
logs cascade via `script_id` FK), then deletes the app row (domains and
slug-history cascade off it). Without `?force=true` the handler still
returns the same `409 HasScripts { script_count }` payload it always did.
Frontend: a new `ConfirmModal.svelte` replaces the bare `window.confirm`
on this page. It's reusable — danger/neutral variants, optional
GitHub-style "type the slug to confirm" gate, ESC/backdrop cancel,
busy state, and a generic body slot — so future destructive actions can
adopt the same pattern instead of growing more browser dialogs. The app
delete confirmation now spells out exactly what disappears (script
count, domain claim list, "all routes & logs") and only enables the red
button once the slug is retyped. The domain-claim delete is also
wired through the modal so this page no longer uses `window.confirm`
anywhere.

Apps become the isolation boundary for scripts, routes, domains, and
later data. Doing this now — while the surface is small — avoids
several migrations on populated tables once v1.1 data-plane services
ship.
Schema (migration 0005_apps.sql):
- New tables: apps, app_domains (with shape_key UNIQUE for collision
detection), app_slug_history (for permanent slug-rename redirects).
- app_id added to scripts, routes, execution_logs (non-null, cascading
rules per row).
- Script-name uniqueness becomes per-app; the route unique index is
swapped for an app-scoped version.
- The "default" app is seeded unconditionally with a localhost claim;
existing scripts/routes backfill into it. Fresh installs additionally
get the Hello World seed via seed_hello_world_if_fresh after
migrations run (idempotent — only fires when the default app has no
scripts).
Orchestrator dispatch is two-phase: AppDomainTable resolves Host →
app_id (most-specific match wins, exact beats wildcard), then the
existing route matcher runs against that app's partitioned slice via
RouteTable. Unknown hosts return 404 at the app layer with a clear
message; /api/v1/execute/{id} still works as the implicit
__internal__ claim, decoupled from any public domain.
Manager API: full CRUD for /api/v1/admin/apps/* and
/api/v1/admin/apps/{id_or_slug}/domains/*, with slug:check + force
takeover semantics implementing the rename-history flow (two-step
check → confirm, never a single endpoint). Script create requires
app_id; list accepts ?app= filter. Route create validates host
against the parent app's claims; conflict detection stays strictly
intra-app.
Dashboard: /admin/apps and /admin/apps/{slug} (overview + scripts +
domains + settings tabs, with slug-history-aware redirects). Root
path redirects to the apps list. Script detail page gains an app
breadcrumb and threads app_id into the route preview.
Deferred per design: per-app admin roles. The require_admin middleware
remains the seam where role checks will slot in later.
Blueprint §11.5 and roadmap updated to reflect what shipped; docs/
versioning.md notes the schema 3 → 5 bump.
