Two defense-in-depth fixes on cron output path handling:
1. cron/jobs.py:update_job() rejects mutation of the immutable 'id' field
(raises ValueError). Dashboard PUT /api/cron/jobs/{id} converts this to
HTTP 400. Without this, an attacker who can reach the update endpoint
could rename a job's id to '../escape' and move its output directory
outside OUTPUT_DIR.
2. cron/jobs.py:_job_output_dir() validates job IDs before composing
paths: rejects '.', '..', '/', '\\', absolute paths, and Windows drive
prefixes. Used by save_job_output() and remove_job() so legacy unsafe
IDs (from before this guard) fail closed rather than half-applying a
shutil.rmtree or output write outside the sandbox.
Tests:
- update_job rejects {'id': '../escape'} without renaming
- remove_job(legacy '../escape' id) raises ValueError without deleting
files outside OUTPUT_DIR or removing the job from the store
- save_job_output rejects '..', './escape', 'nested/escape',
absolute paths
- dashboard PUT /api/cron/jobs/{id} with {'id': '../escape'} returns
400, job list unchanged
Salvaged from PR #29826 by @zapabob. Simplified implementation:
- Dropped a 23-line _validate_job_output_id() helper using Path.parts
semantics. The inline check (path separators + dot-components +
is_absolute) is shorter and behaviorally identical.
- Dropped the secondary OUTPUT_DIR.resolve()/relative_to() check —
redundant once we reject any path separator at the input boundary.
- Dropped the _docs/2026-05-21_cron-output-path-hardening_codex.md
planning artifact (we don't check planning docs into the repo).

Salvages #27568 by @SerenityTn. Dashboard cron page now lists cron
jobs from all profiles, with profile-aware filter UI and storage
routing. Includes test coverage for cross-profile listing, mutation,
deletion, and validation.
Also fixes orphan conflict markers in config.py left by an earlier
salvage merge (kanban.dispatch_stale_timeout_seconds was double-nested
in HEAD/PR markers from #28452 salvage of #23790).
