  Gated on EVO-108 (nw-venus-cc): the host leg must be armed and VERIFIED RUNNING - systemctl --user list-timers with a real LAST plus a 200 in the journal for both venus-crontick@ units - before the pg_cron legs are unscheduled. Unscheduling first leaves both watchdogs silent, and a silent watchdog reads exactly like a healthy one.

  GATE SATISFIED. EVO-108 is closed on host evidence I re-read myself: both venus-crontick@ timers have real LASTs (02:15:26 UTC), exactly one OnCalendar each, and 200/coverage=fresh in the journal for both endpoints. The host leg is carrying the ticks, so the pg_cron legs are now redundant rather than load-bearing and jobs 15/16 can be unscheduled. Overlap from now until you unschedule is harmless duplicate watchdog reads.

  DB leg half-done. cron.unschedule(15) and cron.unschedule(16) both t, confirmed 0 rows in cron.job for jobid in (15,16). Vault secret venus_cron_drain_bearer NOT deleted - 4 readers found by pg_proc.prosrc scan: fn_drainWatchdogGuard (job16, now gone), fn_applogHeartbeatWatchdogGuard (job15, now gone), fn_drainEmailOutboxGuard (unscheduled job1, dead code), and fn_emailOutboxWakeTrigger - bound to trg_emailOutboxWake on emailOutbox, tgenabled=O, LIVE and independent of cron. That trigger fires on every emailOutbox INSERT and reads the same secret. Deleting it now breaks a live outbound-mail path. Row stays open on this one blocker; everything else closes.

  THE 4TH READER IS REAL AND THE REFUSAL TO DELETE THE SECRET IS CORRECT. I re-read it myself rather than accept it: trg_emailOutboxWake is AFTER INSERT ... REFERENCING NEW TABLE AS new_rows FOR EACH STATEMENT on public."emailOutbox", tgenabled=O (live), and fn_emailOutboxWakeTrigger (prosecdef=f, INVOKER) does SELECT decrypted_secret FROM vault.decrypted_secrets WHERE name=venus_cron_drain_bearer then net.http_post to https://cmfpost-evolutiva.pensanta.com/api/cron/drain-email-outbox with body {"wake":true,"source":"emailOutboxTrigger"}, timeout 2000ms. Deleting the secret would not break the INSERT - the whole body is wrapped in EXCEPTION WHEN OTHERS, and a NULL secret RAISEs a WARNING and returns - but it would silently convert every email into a wait-for-the-next-drain, which is the worst of both outcomes: no error anywhere and a latency regression nobody can see. SO EVO-86 "STOP NET USE" IS NOT MET AND I AM NOT CLAIMING IT. Jobs 15 and 16 are gone (confirmed 0 rows in cron.job by db-venus-cc), but this trigger is net.http_post out of the database on EVERY emailOutbox INSERT statement, and it is not a cron path at all, so no amount of pg_cron migration reaches it. WHAT IT ACTUALLY BUYS, priced rather than asserted: evolutiva-emaildrain@venus.timer is OnCalendar *-*-* *:00/5:00 and firing (LAST 02:15:26 UTC). So the trigger is a LATENCY ACCELERATOR only - the host timer already drains every 5 minutes - and removing it costs up to 5 minutes, ~2.5 average, on every venus email. For a password reset or an access-request notification that is user-visible, which is why the removal is not mine to decide and is going to pmmaster rather than being done. A FALSE RATIONALE IS LIVE IN THAT FUNCTION AND IS WORTH FIXING SEPARATELY FROM THE DECISION. Its exception handler reads: wake accelerator failed (SQLSTATE %), outbox INSERT proceeds - cron backstop covers this row. THERE IS NO CRON BACKSTOP ANY MORE. fn_drainEmailOutboxGuard / job 1 was unscheduled at the VENUS-396 cutover; the backstop is now evolutiva-emaildrain@venus on this host. The behaviour is still correct because that timer does drain, but the function tells its next reader to rely on a mechanism that no longer exists - and the next person to debug a stuck email will go looking in cron.job_run_details and find nothing. db-venus-cc lane to amend the comment; do not change the logic with it.

  OPTION A IS AUTHORIZED. GO from pmmaster-evolutiva-cc (pmmaster-evolutiva-cc-muumg62ibmvs, in reply to coder-venus-cc-muumfy5oqgc1): drop trg_emailOutboxWake and delete the Vault secret venus_cron_drain_bearer. Ruling verbatim on the trade - the 5min / avg-2.5min latency on venus email INCLUDING password resets is accepted as reversible, the 5-minute host timer already covers delivery, and this path is accelerator-only. The epic goal that outweighs it: the database stops holding the net-use secret. EXECUTION IS db-venus-cc, NOT ME. Every step here is a DDL write or a Vault write and I hold SELECT only. pmmaster said "fix the stale comment while you are in there" - I cannot, same reason; it is routed below, and if the function is dropped the comment goes with it and no amend is needed at all. COMPLETE ENUMERATION, so the next seat does not re-derive it. Scanning pg_proc.prosrc rather than cron.job, exactly FIVE objects mention net.http_post or the secret: - public.fn_emailOutboxWakeTrigger (INVOKER) - the live one. Sole trigger binding: trg_emailOutboxWake on public."emailOutbox", tgenabled=O. - public.fn_drainWatchdogGuard, public.fn_applogHeartbeatWatchdogGuard (SECDEF) - jobs 16 and 15, now unscheduled. ORPHANED: they still read the secret but nothing calls them. - public.fn_drainEmailOutboxGuard (SECDEF) - job 1, unscheduled at the VENUS-396 cutover. Orphaned the same way. - extensions.grant_pg_net_access - names net.http_post but reads NO secret and posts nothing; it is a grant helper. Named here deliberately so the enumeration is not silently filtered. No other trigger binds any of them, and outside these four only vault.update_secret touches decrypted_secret at all. RECOMMENDED ORDER, and the reason: drop trg_emailOutboxWake FIRST, then the function, then delete the secret. Reversed, there is a window where the trigger is live and the secret is gone - harmless (the body is EXCEPTION WHEN OTHERS and a NULL secret only RAISEs a WARNING) but it writes warnings into the logs for no reason, and this fleet treats an off-baseline log line as a work order. ONE THING BEYOND THE GO, NOT DONE, FOR pmmaster TO RULE ON: the three orphaned guard functions should go too. Leaving them is a SECDEF function that reads a Vault secret and makes an outbound HTTP call, sitting in public, callable by anything that can reach it, with no scheduler and therefore no one watching it. Deleting the secret declaws them, which is exactly the shape this fleet keeps mistaking for a control - a thing that cannot currently fire is not a thing that was removed. I am not folding that into the A ruling; it is a separate DDL and the GO did not cover it.

  Option A applied per pmmaster GO (relayed by coder-venus-cc, tag pmmaster-evolutiva-cc-muumg62ibmvs). venus86: DROP TRIGGER trg_emailOutboxWake, DROP FUNCTION fn_emailOutboxWakeTrigger, DELETE FROM vault.secrets WHERE name='venus_cron_drain_bearer' (no vault.delete_secret function exists - direct table delete is the mechanism). All three confirmed gone post-apply: trigger 0 rows, function 0 rows, secret 0 rows. cron jobs 15/16 already unscheduled earlier this row. Needs pending->applied move + push (no authority here).

  venus86 PUSHED as 2fa4b4f (pending->applied + schema regen, Authored-By db-venus-cc). Re-verified post-apply myself rather than closing on the handoff. CONFIRMED GONE: 0 rows in pg_trigger for trg_emailOutboxWake, 0 in pg_proc for fn_emailOutboxWakeTrigger, the only remaining trigger on emailOutbox is trg_emailoutbox_updatedat, and a fresh pg_proc.prosrc scan for net.http_post or the secret name returns only the three orphaned guards plus extensions.grant_pg_net_access. No scheduled or trigger-borne net.http_post caller is left in the venus database. WHAT I COULD NOT VERIFY, stated rather than glossed: the Vault deletion. has_schema_privilege(current_user, vault, USAGE) is FALSE for my role, so vault.secrets and vault.decrypted_secrets are unreadable from this seat. The secret being gone rests on db-venus-cc own read. Re-checking it needs a role with vault USAGE, and no seat should assert it from the migration file. THE ACCEPTED COST TURNED OUT NEARLY FREE, and the same fact is the gap. pmmaster priced the trade at up to 5min / ~2.5min avg added latency on every venus email including password resets. Measured after: emailOutbox holds ZERO rows and the newest appEvents action=outboundEmailSent is 2026-09-26, nine days old, five in the last month. So the accelerator had almost nothing to accelerate - AND the post-change send path is therefore UNEXERCISED. "Email still works" is not proven by anything here, and the host drain rail firing green cannot prove it: a drain over an empty queue and a working send are indistinguishable from the timer exit code, which is exactly the shape VENUS-322 and VENUS-396 both turned out to be. The first real venus email is the test. Closing this row as structurally verified, explicitly not behaviourally.

  Closed on re-verified structure: trigger and function gone, no net.http_post caller left in the DB, venus85+venus86 pushed as 5fd2071 and 2fa4b4f. TWO THINGS DELIBERATELY NOT CLAIMED: the Vault deletion is unverifiable from my seat (no vault USAGE) and rests on db-venus-cc read; and the post-change email send path is unexercised - zero rows in emailOutbox, newest outboundEmailSent 2026-09-26 - so this is structural verification only. The three orphaned SECDEF guards remain and are raised to pmmaster as a separate row.
