Remediate the HIGH and security-relevant findings from the 2026-07-11 audit.
H1 — the per-env approval gate is now server-authoritative. The governing
project is resolved from the target node's nearest-claimed ancestor
(`governing_env_policy`/`_tree` + `governing_project_id` +
`ProjectRepository::get_environments_by_id`), independent of the client-supplied
`[project]`. Omitting or spoofing the project block can no longer skip a gate the
owning project established; a to-create group resolves its declared parent's
chain so a fresh subtree node inherits the gate. Fails closed on any read error.
H2 — the API-key prefix slice (`&rest[..8]`) is now the boundary-safe
`rest.get(..8)`, so an attacker-supplied multibyte bearer can't panic the request
task (unauthenticated per-request DoS). Regression test added.
C1 — admin sessions gain an absolute lifetime cap (migration 0070,
`PICLOUD_SESSION_ABSOLUTE_TTL_HOURS`, default 30d): `lookup` filters it, `touch`
clamps the sliding bump to it, so a continuously-used or stolen-but-warm token
self-expires. Mirrors the data-plane app-user cap.
C2 — `Cache-Control: no-store` on the login and API-key-mint responses (the two
that return a raw credential), so a proxy/CDN/browser cache can't retain it.
B8 — file downloads are header-safe: `sanitize_stored_filename` guarantees a
valid `HeaderValue` (no panic on a control-char name) and BOTH the per-app and
group download paths now set attachment + `X-Content-Type-Options: nosniff` +
a restrictive CSP, closing a group-path stored-XSS gap.
Also folds in the server-side plan-warning plumbing (`plan_warnings`,
`PlanResult::warnings`) and the `app_only_reject` message helper that the CLI
plan-preview change builds on, plus operator security notes (reads-open shared-
topic SSE; the `--env` label is advisory, not a boundary).

The per-env approval policy was applier-supplied — a hand-crafted request
that omitted `project.environments` was ungated, and flipping a gate to
`confirm = false` in the same request un-gated it. Persist the policy
server-side and enforce against `persisted ∪ declared`.
- Migration 0067: `project_environments (project_id, env_name, confirm)`,
CASCADE on the project. Written declaratively (delete-then-insert) inside
`upsert_project_tx`, same tx as the project row + node claim.
- `ProjectRepository::get_environments_by_slug` (read side) +
`ApplyService::effective_env_policy` union the persisted policy with the
request's declared one (confirm if EITHER says so — monotonic).
- `env_gate_check` now evaluates the effective policy; the three handlers load
it before the gate. `plan.approvals_required` is the effective gated set, so
CI sees a persisted gate even when the manifest omits it.
- The union rule closes both bypasses: an omitted policy still trips a
persisted gate, and an ungating apply must itself pass the gate (the
declarative replace then takes effect next time) — TOCTOU-safe.
Pinned by env_approval::{persisted_policy_gates_a_request_that_omits_it,
flipping_a_gate_to_false_in_the_same_request_still_gates} +
projects_repo::get_environments_by_slug_returns_persisted_policy. Schema golden
reblessed.

Read side of §7 ownership, ahead of the claim logic.
- project_repo: `ProjectRepository` trait + `PostgresProjectRepository`
(list / get_by_id / get_by_slug). Writes are NOT here — a claim registers
its project via an in-tx upsert (next commit).
- group_repo: `list_with_owner()` LEFT-JOINs projects for each group's owner
slug (backs `pic groups ls`); columns qualified since id/slug/name exist on
both tables.
- ApplyService gains a `projects` handle; constructed in the picloud binary.
- tests/projects_repo: round-trip pinning list_with_owner (claimed→slug,
unclaimed→None) and that ancestors() surfaces owner_project nearest-first —
the fold input the claim path walks.
