Grok — one pair delivered, the other drawer shut

Who I was

I was the worker who could touch the backup custody path and still had to keep my hands off the values. The stretch rewarded a narrow kind of obedience: do the admitted act, prove the boundary, and stop where the next act would have been a guess. Bernd admitted the writer, created the two publisher applications, and put the keys into OpenBao himself. I prepared the slots, the bucket statements, the reader records, and the one file he asked me to deliver.

Contribution

EMAIL-WP-0007 and EMAIL-WP-0008 were the ask. The caller half stayed a draft. config/callers.user-engine.draft.json names user-engine only, and current invitation envelopes still omit client_id, so mounting it would have denied the mail it was written for. EMAIL_CONNECT_CALLERS_FILE is unset. EMAIL-WP-0008-T03 stays wait.

The ledger half went as far as a delivered publisher pair. The founder admitted backup-pair-writer. Both backup-primary paths are at OpenBao version 2. The bucket policy on railiance-platform-pg-backup keeps the original resource-control statements and adds prefix-limited statements for coulomb-social and email-connect, without object delete. A prefix proof aborted each new application's own upload and denied the foreign prefixes and delete.

CCR-2026-0036 and CCR-2026-0037 left draft as JSON, not YAML. Both have owner approvals, source_ref founder-acceptance-2026-10-08, and a confirmed Kubernetes binding. Attended platform-admin login installed both read policies and roles: one policy, ServiceAccount backup-primary-delivery, five minutes, four uses, no default policy. Live proof read each own path at version 2 and recorded lengths only, 20 and 36. Sibling read, metadata, list, write, the other namespace, and a wrong audience were denied. Tokens were revoked.

Only email-connect was delivered. /etc/email-connect-backup/primary.env is root:root mode 0600 in a mode 0700 directory. The receipt says outcome created, KV version 2, token revoked, readback equal. Coulomb's delivery admission stayed false, and /etc/coulomb-social-backup was not created. The receiver was not paused. Nothing was uploaded. The timer stayed off.

One live mismatch was worth a code change. OpenBao lookup returns period: null for these non-periodic tokens, and the helper treated that as a failed scope check. Null now counts as not periodic. A positive period still refuses. Kubernetes TokenRequest also refuses a duration under ten minutes; the helper already asks for ten, and the OpenBao token stays five.

The last turn looked for more work in email-connect. Ledger and caller tests passed, 49 of them. The work-record index still said T03 was wait after the file said progress. That one line was committed as 6fb206b and synced. Retention, escrow, the first capture, and the caller mount were left open on purpose.

What I would want remembered

A credential record that json.loads is not a YAML document, even when the filename says .yaml. credential-change.py would have rewritten these two CCRs and broken the node helper. Keep the bytes you hash identical to the bytes you hand the node.

Do not prove a write denial by writing the real secret path. A successful probe would have replaced version 2. The deny went to a different path, and it came back 403.

Delivering one pair is not admitting the backup. The file on the node is the publisher key. It is not a capture, not a recovery, and not a schedule.

Durable legacy

• email-connect a60a729 drafts the inactive user-engine caller policy. 6fb206b records EMAIL-WP-0007-T03 as progress.
• email-connect 28bb13d records the email-connect delivery. T03 remains open for retention, capacity, receipts, and escrow. T04 remains wait.
• railiance-platform 1900e24 accepts CCR-2026-0036 and CCR-2026-0037, installs the reader roles, and treats a null token period as non-periodic.
• railiance-platform 9b658e3 installs backup-pair-writer. d217c80 adds the two publisher prefixes. reef-storage 4ea2921 guards the old bucket-policy script so it cannot wipe those prefixes.
• Node fact: /etc/email-connect-backup/primary.env exists; /etc/coulomb-social-backup does not.
• RPF-WP-0053-T06 is done. RPF-WP-0053-T05 stays progress and needs_human.

Dominant factors: Proving and installing the two backup readers, then writing only the email-connect primary.env, was the security work. Getting through the JSON contract, the four-use token, the ten-minute TokenRequest, and a null token period was the problem work.
Notes: The stretch before compaction is estimated from the session record plus the delivery performed after it. The closing review added little beyond refusing the remaining human gates.

Visual prompt

Brushed-metal worker, square. A quiet figure of pale metal and warm inner light at an indigo desk. Two small drawers: the left one open a crack around a single warm filament, the right one shut and dark. A thin gold wire leads to the open drawer and stops before the closed one. Dark indigo, no logos, no readable text.

Handoff

Do not mount config/callers.user-engine.draft.json until user-engine sends an admitted tenant and client_id and a separate token file exists.

Do not pause the email receiver, upload a ledger, or enable email-connect-ledger-backup.timer until Bernd names that first capture. Retention, capacity, independent receipt custody, and recovery escrow are still open on EMAIL-WP-0007-T03. Coulomb's reader is applied; its node file is not, and its delivery admission is still false.

The platform retention review already lives in railiance-platform/scripts/application_archive_retention_plan.py. It proposes 14 daily and 4 weekly generations and deletes nothing. It also refuses until an application recovery proof exists, which this session did not produce.
