kind: credential-change-request
schema_version: 1
request_type: workload-kv-read
title: Name the dedicated reuse-surface hub-writer caller
status: applied
created: '2026-10-14'
updated: '2026-10-14'
requester:
  agent: ops-mason
  reason: CUST-WP-0081 / State Hub message 08b254af. CCR-2026-0005 is active and does
    not name a caller. Entity 4a1f663c-0621-0483-edd0-f852274f4b6b carries default,
    operator-custody and platform-admin, so its token can reach the data path, the
    metadata path and siblings. Do not attach workload-kv-read-reuse-surface-runtime
    to that entity. Bind a new OIDC role to a different principal. No secret value
    is rotated or read by this request.

    decision: filed_proposed
    comment: Filed from ops-mason fd2c5a5 (State Hub 3642bdc4, MASON-WP-0011). Status
      stays proposed. bound_claims_confirmed stays false until key-cape confirms group
      reuse-surface-hub-writers and a member entity other than 4a1f663c-0621-0483-edd0-f852274f4b6b.
      The caller policy file is unchanged; apply, after platform-operator and reuse-surface-owner
      approval, is what adds lookup-self and revoke-self. CCR-2026-0005 remains the
      KV and ESO authority. No KV write and no attachment to the platform-admin entity.

    decision: approved
    comment: Founder go-ahead 2026-10-14. Approves CCR-2026-0044 as platform-operator
      and reuse-surface-owner. Group reuse-surface-hub-writers, member bernd.worsch-3,
      second factor enrolled, entity f94b7c34-e151-30bb-b473-df3ccdbb9bf1. That entity
      is not 4a1f663c-0621-0483-edd0-f852274f4b6b. No KV write. Do not attach the
      policy to the admin entity.

    decision: binding_confirmed
    comment: Bound claims are groups=reuse-surface-hub-writers and /assurance/level=aal2.
      Member is bernd.worsch-3, entity f94b7c34-e151-30bb-b473-df3ccdbb9bf1. The apply
      checks that entity's policy names and stops if platform-admin or operator-custody
      is present.

  resolvable: false
  readiness: pending-review
risk:
  classification: high
  notes:
  - REUSE_SURFACE_TOKEN writes to the production federation hub. This request does
    not read or rotate it.
  - The platform-admin entity must not receive this policy. OpenBao merges entity
    policies into every token for that entity.
  - The ESO policy workload-kv-read-reuse-surface-runtime-eso stays on its Kubernetes
    role. This role does not attach it.
  - bound_claims_confirmed stays false until key-cape confirms group reuse-surface-hub-writers
    and a member entity other than 4a1f663c-0621-0483-edd0-f852274f4b6b.
  - Public bao.coulomb.social ingress is not a callback. Use the workstation tunnel.
verification:
  positive:
  - A member token's policy set is exactly workload-kv-read-reuse-surface-runtime.
  - That token's capabilities are read on the exact data path and the exact metadata
    path.
  negative:
  - The same token is deny on platform/data/workloads/reuse/reuse-surface, its metadata
    parent, and platform/data/workloads/issue-core/issue-core/issue-core-runtime.
  - A principal outside reuse-surface-hub-writers is refused by the role.
  - Entity 4a1f663c-0621-0483-edd0-f852274f4b6b is not the member token's entity.
  activation_conditions:
  - platform-operator and reuse-surface-owner approve this caller binding.
  - key-cape confirms the group and that the member entity has no platform-admin or
    operator-custody identity policy.
  - Founder applies policy and role through the delegated applier. No KV write.
  - scripts/verify-reuse-surface-hub-writer.py member and non-member both pass. Receipts
    stay mode 0600 and contain no token or field value.
  evidence:

    actor: founder
    kind: delegated_metadata_apply
    result: passed
    details:
    - Delegated metadata applier ran as founder using local bao CLI ambient authority.
    - 'Policy metadata write: sys/policies/acl/workload-kv-read-reuse-surface-runtime'
    - 'Auth role metadata write: auth/netkingdom/role/reuse-surface-hub-writer-workload-kv-read'
    - No secret values were read, written, printed, or accepted in argv.
lifecycle:
  deactivate: delete auth/netkingdom/role/reuse-surface-hub-writer-workload-kv-read.
    Leave the KV path, the ESO role, and CCR-2026-0005 delivery in place.
  rotate: unchanged from CCR-2026-0005. This request does not rotate field values.
  compromised: detach the role, revoke outstanding tokens for the role, and follow
    the CCR-2026-0005 compromise procedure if a field value was exposed.
