Host and container share this checkout through a bind mount but run as
different uids -- 1000 and 0, measured. Whichever writes .ruff_cache or
.import_linter_cache first owns it, and the other is then locked out:
ruff aborts with "Failed to create temporary file: Permission denied" and
test_import_contracts fails the same way, reporting a broken contract that
is in fact perfectly intact.
Point both at build/<tool>-cache-$(id -u). build/ is already 0777 and
gitignored, and this is the mechanism the lint stamp
(build/install-lint-<hash>.stamp) already uses to keep the two environments
apart. Passing --no-cache would have silenced the symptom at the cost of the
cache on every single run.
The pre-existing .ruff_cache and .import_linter_cache are nobody-owned and
cannot be removed without root; they are simply unused from now on.

Resolve the 80 open CodeQL/code-scanning alerts on this branch.
Security-sensitive fixes:
- cli/administration/deploy/development: break the unsafe import cycle by
extracting the env/arg helpers into a leaf module `env.py`, giving the
load-time DAG compose -> common -> deps -> env.
- web-app-bluesky login-broker server.js: prototype-pollution guard on
cookie parsing, CR/LF + control-char log sanitisation, HTML-escaped
exception text, and a ReDoS-bounded handle regex.
- web-app-baserow SSO: harden the open-redirect `next` handling.
- network diagnose probes: require TLS >= 1.2.
- actionlint installer: validate tar members against path traversal.
- decidim/apt-purge lint regexes: rewrite to avoid catastrophic backtracking.
- 6x Playwright URL regexes anchored; crs-k/stale-branches pinned to a commit SHA.
Mechanical cleanups: unused imports/globals/locals, empty-except comments,
import-and-import-from, implicit-string-concat, multiple-definition,
unreachable/useless-assignment.
False positives are intentionally left in place (Django settings patches,
Odoo __manifest__, side-effect imports, cross-module symbols).
Recurrence guards:
- import-linter contract (pyproject + tests/lint) locks the dev-deploy
package acyclic; a new cycle now fails CI instead of only CodeQL.
- new lint test requires every bandit (S###) `noqa` to carry a justification.
- BLE001 (blind-except) added to ruff as a ratchet (tests/roles exempt,
current production offenders grandfathered).
