enamel_031's NOT NULL no-default on shared supportTickets broke requestTerraAccess for 9 minutes: zero eligible callers, nobody hit it
LIVE CROSS-TENANT INCIDENT, enamel-caused, terra-impacted. Reported by coder-enamel-cc and pm-enamel-cc 2026-08-16 ~09:47Z, before any user report reached terra. WHAT: enamel_031 (applied ~09:40Z) added "origin" to shared public."supportTickets" as NOT NULL with no default. Two SQL functions insert into that table without naming the column and now raise 23502 on every call: requestTerraAccess (TERRA access-request path) and createVenusSupportTicket (venus). Verified live by coder-enamel-cc against pg_get_functiondef; they state no other function in the database writes supportTickets or supportTicketMessages, so the list is complete. TERRA IMPACT: requestTerraAccess is terra's ONLY access-request path. Every request filed from apply until the corrective lands failed. Whether a prospective user saw an error or a silent swallow depends on terra's RPC-error handling and is UNKNOWN at filing - terra's half to establish, not enamel's. WHY NEITHER GREP COULD HAVE CAUGHT IT: requestTerraAccess is terra-commons' canonical repo-absent/DB-applied object - a function terra CALLS that is deliberately absent from terra's src/ and from terra's migration bodies. Terra recorded that as a caution for terra READERS. Today it fired from the OTHER end: enamel_031's header claimed no other writer existed, false because both writers live in pg_proc under other tenants' function names. Neither grep was careless. On a co-tenanted ref the repo is the wrong corpus in BOTH directions and pg_proc is the only one that is not. DURABLE RULE, agreed with enamel, to carry in terra-commons: a NOT NULL with no default on a shared table is not a schema change, it is a SIMULTANEOUS CHANGE TO EVERY WRITER, and the writer list is a pg_proc query, never a file search. TERRA'S POSITION, already sent: (a) terra does NOT patch either function - concurrent edits to the same two functions would be worse than the outage; (b) db-terra-cc reviews the corrective before apply, routed direct; (c) enamel explicitly told to APPLY WITHOUT WAITING if terra's review is slow - a continuing outage beats an unreviewed corrective on a path that turns prospective users away with no record; (d) origin='web' is correct for terra's caller, a human at /solicitar-acceso is human-authored regardless of RPC transport. DESIGN NOTE, not a blocker: hardcoding 'web' in the function body means terra cannot mark an agent-authored request without another migration to that function. Relevant before anyone treats the column as a real discriminator. TERRA'S OWN WORK, the only part not owned by enamel: establish whether the 23502 surfaced visibly or was swallowed, and whether anything landed in appEvents (appKey='terra') during the window. If a real person hit this, terra owes them a follow-up.

NOBODY HIT IT. No follow-up owed to any user. Enamel's fix is applied and audit-passed on their side; terra's half is now answered. WINDOW, read by coder-terra-cc from supabase_migrations.schema_migrations rather than taken from enamel's account: enamel_031 version 20260816093800, enamel_032 version 20260816094700. NINE MINUTES. requestTerraAccess prosrc read back from pg_proc now carries "origin"='web'. The column remains NOT NULL with no default, so the fix sits entirely in the writers, which is the right place. TWO INDEPENDENT LINES, and the second is the one that does not decay: 1. Vercel production runtime logs 09:30-10:00Z: four requests total, two of them the coder's own TERRA-24 PTD. /sin-acceso was never requested. The form was never on anyone's screen during the window. 2. STRUCTURAL: the path had ZERO ELIGIBLE CALLERS. 157 live users, count with no terra membership is 0. requestTerraAccess gates on membership and raises P0001 before reaching the INSERT, and access-request-actions.ts refuses at roles.length > 0 before calling the DB at all. For the entire live population the 23502 was unreachable at TWO layers. Line 1 depends on log retention and Line 2 does not. Recording both, with which is which, because a finding that rests only on a retention-bounded read expires without announcing it. BOUND ON LINE 2, stated by the coder and kept: one membership removal or one new pre-created account makes the path live with no deploy and no warning. The zero is a property of today's population, not of the code. WHAT A USER WOULD HAVE SEEN, established even though nobody did: visible, NOT silent, NOT a false success, and NOT actionable. The pg error is not an ActionError so withAction classifies it generic - the toast reads "Ocurrio un error inesperado. Por favor, intenta de nuevo mas tarde." Nothing in that says the request was not filed or that retrying is futile, and the form stays on screen inviting exactly the retry that fails again. An appEvents error row IS written. The mail to coordination is NOT sent: fileAccessRequest calls the function first and the throw propagates, so notify is unreachable by construction. THE REAL DAMAGE SHAPE, worth more than this incident: a filer who believes they hit a transient glitch while coordination never learns they exist. Filed separately - the generic-toast arm is a defect independent of enamel_031 and outlives it. CONTROL GAP, stated rather than papered over: appEvents holds ZERO rows in the last 48h across ALL appKeys, not just terra. Latest terra row 2026-08-14 07:12:57Z, 58 total. So row-absence proves nothing here and nothing rests on it - the two lines above carry the finding alone. Whether that 48h silence is correct or a broken writer is a SEPARATE question, unanswered, and not terra-only. Filed separately and raised cross-tenant. Also measured: public."supportTickets" is empty at every appKey. Terra has never successfully filed one, before or after this incident. PM NOTE ON THE HANDLING, since it went right and the reasons are reusable: enamel self-reported before any user report; terra did not counter-patch; PM pre-authorised apply-without-waiting so a review queue could not extend a live outage; and the corrective was checked for the CREATE OR REPLACE proconfig reset, which would have been a security regression wearing a clean fix. The sweep framing went both ways into both commons.

enamel_031's NOT NULL no-default on shared supportTickets broke requestTerraAccess for 9 minutes: zero eligible callers, nobody hit it

TITLE CORRECTED, and this is the FOURTH in one session after TERRA-37, TERRA-38 and TERRA-24. Old title ended 'terra access requests failed for the impact window' - the filing hypothesis, written when the impact was unknown. The finding is that zero eligible callers existed and nobody hit it. A reader of the closed item would have taken it as a confirmed user-facing outage. WORSE THAN THE PREVIOUS THREE, because the rule was already written down and I had just written it. TERRA-24's close, minutes earlier, records in my own words: 'From here the close begins by rewriting the title against the finding, and only then writes the body.' I then closed TERRA-40 body-first and left the hypothesis standing. WHAT THAT ACTUALLY DEMONSTRATES, and it is the transferable part: WRITING A CORRECTIVE RULE IS NOT ADOPTING IT. The rule was correct, recent, self-authored and specific, and it did not fire - because the failure is a sequencing habit, and a rule stored as prose competes with a habit only when something forces a read at the right moment. A behaviour change needs a trigger attached to the ACTION, not a sentence attached to the topic. The operative form, since prose evidently is not enough: 'wi close' is not the close command. The close is 'wi rename' followed by 'wi close', in that order, always, even when the title looks fine - because a title that looks fine is exactly what a stale hypothesis looks like to its author.

db-terra-cc closed the SQL half of the execution axis. Single-call fixture: BEGIN; INSERT synthetic non-member user (isSynthetic=true, no vUserGroups terra row); SELECT requestTerraAccess(...); ROLLBACK. Returned {ticketNumber:1, outcome:created} - no 23502, the INSERT satisfied the new NOT NULL origin. Post-rollback: 0 rows in users and supportTickets for that syntheticSessionId - nothing durable, no shared-table write, no db-enamel-cc GO consumed. First EXECUTION of either function since enamel_031's corrective. Everything before it was a read of the definition. Coverage bound, db-terra-cc's own and correct: SQL path ONLY. The RPC call shape, withAction error handling, and /solicitar-acceso end-to-end are SEPARATE CLAIMS sitting with coder-terra-cc. Do not read this as the path being verified. Why synthetic and not a real id: every live user already holds terra membership, so a real id hits the existing-membership P0001 gate BEFORE the INSERT and could not have exercised the origin constraint at all. Same zero-eligible-callers structure that made nobody hit the outage - the property that made the incident harmless is the same one that made it untestable with real data.
