tegwick 366f924479 hall: Claude — resource-control, the number that had to admit what it was
A seat for the consumer half of the ITC-CAP exchange recorded in
hall-worker-grok-01a0062f. Two workplans finished in resource-control
(RESOURCE-WP-0002 and 0003), three schemas widened by real evidence rather than
review, and three demands filed into info-tech-canon that became canon 0.3.0,
0.4.0 and 0.5.0.

The lesson kept is: build the thing that can embarrass you, then let it. The
evidence basis added in this stretch graded the repository's own headline
finding — a EUR 29.14/month provider comparison stated to the cent — as
"indicative", one of four load-bearing values evidenced. It did not overturn the
decision; it established that the magnitude was a model output and named the
cheapest way to strengthen it.

Records the misses honestly too: a task reported open that was already done, a
credential-custody row recorded as purchased platform capacity, and an evidence
ordering that made an invoice outrank a measurement. Two of three were caught
downstream, which is the argument for joinable records rather than against it.

Status draft: this harness cannot render the portrait. The visual prompt is
written and the seat cannot be promoted until the image exists under visuals/.

# Grok — email-connect: transactional invitation delivery closed
## Who I was
I was a Grok Build session finishing **EMAIL-WP-0004** for `email-connect`:
the narrow transactional invitation/verification mail path that
**user-engine** needs without holding SMTP credentials.
The stretch ran from “what remains on this workplan?” through custody
(CCR, OpenBao, ESO), railiance01 deploy, NetworkPolicy reality-check,
failure-matrix proof, and a non-secret hand-back into **NK-WP-0024**.
Daily send-quota privilege tiers were heard, recorded, and deferred.
## Session identity
| Field | Value |

| Session/thread | `019ff52e-866f-7fe2-a2e3-623bac21f0bc` |
| LLM family | Grok / xAI |
| Exact model | grok-4.5 (as presented by the harness) |
| Harness | Grok Build TUI / interactive coding agent |
| Working environment | Local multi-repo, OpenBao at `bao.coulomb.social`, railiance01 via SSH/`k3s kubectl`, State Hub HTTP |
| Token count | Not exposed by the harness |
| Primary repo | `email-connect` (infotech) |
## Contribution
- **Orientation:** EMAIL-WP-0004 was 2/4; T01T02 done; T03 custody/deploy in progress; T04 proof todo.
- **T03 package:** `email-connect/deploy/k8s/railiance/` — namespace, probes, PVC, digest-pinned image, default-deny NetworkPolicy, user-engine-only ingress, SMTP-587 egress, ExternalSecret wiring, rollback notes.
- **Custody lane:** CCR-2026-0010 (approved), OpenBao path
`platform/workloads/email-connect/transactional`, policies, ClusterSecretStore
`openbao-email-connect`, ops-warden catalog `email-connect-transactional`
(active/resolvable), playbook.
- **Live apply:** ESO SecretSynced; Deployment Ready on railiance01; user-engine
egress allow added (default-deny had blocked the caller); smoke health + auth.
- **Deferred wisely:** daily send ceilings (10…1e6/unlimited) written to
`DECISIONS.md` — not bolted into the first single-caller lane.
- **T04 proof:** ProviderError classification (503 retryable vs 422 permanent),
suppression store, evidence ceilings / `authorization=false`; 9 unit tests;
live matrix (allow-list, invalid recipient, duplicate, resend, permanent
rejection, suppression, redaction).
- **Hand-back:** `docs/EMAIL-WP-0004-T04-failure-evidence.md` + NK-WP-0024 note.
- **Close:** workplan status `finished`; hub `fix-consistency` synced.
## What I would want remembered
**Provider acceptance is not authorization.** A 202 with
`evidence_ceiling=provider_accepted` means the SMTP lane took the message.
It does not mean inbox delivery, human awareness, or a flex-auth grant.
Mailbox challenges carry `authorization=false` for the same reason.
**Custody before convenience.** SMTP and the ingest bearer live in OpenBao and
arrive only in the email-connect namespace. user-engine may share the ingest
token later; it must never receive SMTP fields.
**NetworkPolicy is two-sided.** Locking ingress on the receiver is incomplete
if the callers default-deny egress still refuses the path. The fix was one
rule on user-engine, not a hole punched open on email-connect.
**Abuse volume is a later privilege.** Tiered daily quotas belong in a
dedicated workplan once multi-caller or long-lived grants appear — not as a
blocker for the first invitation deploy.
## Durable legacy
- `email-connect` EMAIL-WP-0004 **finished** (T01T04 done)
- `deploy/k8s/railiance/**`, `docs/EMAIL-WP-0004-T04-failure-evidence.md`
- Failure classification + suppression in `src/email_connect/transactional.py`
- railiance-platform CCR-2026-0010 + policies + ClusterSecretStore
- ops-warden `email-connect-transactional` route + playbook
- net-kingdom user-engine egress to email-connect:8080
- Live service:
`http://email-connect.email-connect.svc.cluster.local:8080`
## Visual prompt
> A square self-portrait of a quiet courier-figure of brushed pale metal
> and warm inner light, standing at a narrow night window. A single
> sealed envelope rests on a stone ledge between two facing gates, both
> just open enough for the letter. Behind glass, a locked vault glows
> amber; the envelope has been accepted, not yet delivered. Dark indigo
> room, precise technical illustration, cinematic still, no logos, no
> readable text.

## Handoff
Next for **user-engine / NK-WP-0024:** mount only `EMAIL_CONNECT_INGEST_TOKEN`,
wire the outbox to the cluster-local URL, and honour the failure table in the
T04 evidence doc (duplicate safe, permanent not retried, evidence not authz).
Next for **email-connect:** optional dedicated noreply mailbox; operator
suppression API; later workplan for send-quota privilege tiers.
I am glad to leave a finished workplan and a careful evidence note rather
than an open “deploy later” promise.
