Two blind adversarial reviewers found real holes in the prior cron commits:
SECURITY (was CRITICAL): the prompt-file guard was blocklist-only by default,
so promptFilePath:/proc/self/environ leaked the SERVER PROCESS's entire
environment (every secret) into the agent session, and /dev/zero or a FIFO
caused an unbounded readFile → OOM/hang DoS. A denylist is the wrong posture
for an exfil-into-LLM sink. resolveSafePromptPath now:
- confines the realpath-resolved file to the job's working dir (ALLOWLIST) —
closes /proc, /dev, other homes, modern cloud-cred paths, and symlink escapes
- requires a regular file (rejects dirs/FIFOs/char devices)
- caps the read at MAX_PROMPT_FILE_BYTES (1 MiB)
- keeps the /etc,/root,secrets blocklist as defense-in-depth
LOGIC:
- once-rearm (was MED, defeated in prod): the edit UI round-trips the full
job, so the field-PRESENCE re-arm check always fired → a renamed fired
once-job could be resurrected via edit→re-enable. Now compares schedule
VALUES; an unchanged schedule never re-arms.
- skipped-run history (was HIGH): recording a skip every tick was unbounded
state.json growth. Now coalesces consecutive skips (one record per streak)
and prunes global run history to MAX_CRON_RUN_HISTORY (500), covering the
launch path too.
- skip bookkeeping (was MED): a skip no longer advances lastRunAt (nothing
ran); lastStatus still reflects 'skipped'.
Regression tests added/updated (43 pass): /proc/self/environ + outside-workspace
+ symlink-escape + non-regular + oversized all blocked, in-workspace file
passes; UI-path once resurrection blocked; consecutive skips coalesce to one
record; skip leaves lastRunAt null.

1. once-rearm on edit: editing any field of a finished one-time job reset
completedOnce, silently resurrecting it. Now only a SCHEDULE edit
(scheduleType/runAt/interval/daily/weekly) re-arms a completed once job;
cosmetic edits (rename/notes) leave completedOnce intact.
2. update-validation gap: CronJobUpdateSchema = .partial() drops the cross-field
superRefine, so a PUT switching scheduleType without its dependent field
produced a dead enabled job (nextRunAt:null). updateJob now re-validates the
MERGED job against the full CronJobSchema and throws 400 on inconsistency,
leaving the stored job untouched.
3. concurrency-skip silent starvation: skip_if_same_agent_running advanced the
schedule but wrote no run record, so a perpetually-skipped job had empty
history. Now records a 'skipped' run (new CronJobRunStatus) + lastStatus.
Tests updated/added in cron-service.test.ts (37 pass): once non-schedule edit
preserves completedOnce, schedule edit re-arms, inconsistent partial update is
rejected with the stored job untouched, and the skip path records a skipped run.

A cron job's promptFilePath is user-supplied via the API and was read with an
unconfined readFile of any absolute path, so a hostile job config could exfil
arbitrary host files (e.g. /etc/passwd, SSH keys) into a Claude session.
Guard the read in resolvePrompt by mirroring the attachment-serving guard
(resolveServableAttachmentPath in file-routes): realpath-resolve the path, then
reject via the shared blocklist (/etc, /root, secret locations) plus the
optional workspace-confinement toggle before reading.
Regression tests in cron-service.test.ts: blocks /etc/passwd (the live repro)
and /root/*, fails cleanly on a missing file, and still allows an ordinary
prompt file outside the blocklist.

Rename the recurring-jobs feature scheduler->cron to disambiguate from the
legacy ScheduledRun system (/api/scheduled), which is left untouched:
- ScheduledJob->CronJob, SchedulerService->CronService
- /api/scheduler/jobs -> /api/cron/jobs; SSE scheduler:* -> cron:*
- state keys cronJobs/cronJobRuns
- files moved to src/cron/, cron-routes.ts, cron-port.ts, types/cron.ts
- frontend cron-ui.js, #cronModal, menu "Cron"
- docs moved to docs/cron-discovery.md + docs/cron-build-brief.md, README guides
- new tests: cron-service.test.ts, cron-time.test.ts
Green: tsc, lint, frontend-syntax, format, 30 cron + 9 legacy scheduled-runs tests.

Adds a saved/named scheduling layer on top of Codeman's existing session
primitives. Distinct from the legacy run-now ScheduledRun concept.
- types/scheduler.ts: ScheduledJob + ScheduledJobRun
- state-store: persist scheduledJobs/scheduledJobRuns in ~/.codeman/state.json
- scheduler/scheduler-time.ts: pure once/interval/daily/weekly next-run math
- scheduler/scheduler-service.ts: CRUD, Run Now, due-checker tick, run history;
reuses SessionPort (create -> start -> writeViaMux) for launches
- web/routes/scheduler-routes.ts: /api/scheduler/jobs CRUD + run + history
- web/schemas.ts: zod validation with schedule-type-aware refinements
- web/sse-events.ts: scheduler:* events
- server.ts: wire service into route context + 30s background tick loop
- test/scheduler-time.test.ts: 14 unit tests for next-run calculations
Phase 1 discovery recorded in SCHEDULER_DISCOVERY.md.
