# GCP-native Leo goal
## Outcome
Run Leo's Hermes `leoclean` runtime as a fresh GCP service, backed by the V3
LivingIP knowledge base in canonical Cloud SQL, and route Telegram directly to
that verified GCP service.
This is not a VPS lift-and-shift. The existing VPS is never copied into or run
inside GCP. It remains untouched as a temporary comparison and rollback source
until the GCP service has passed soak and restore testing.
## Target architecture
- An immutable `leoclean` image is pulled from Artifact Registry by digest.
- A dedicated GCP service runs Hermes with the `leoclean` profile.
- Cloud SQL PostgreSQL 16 is the canonical V3 knowledge authority.
- Secret Manager supplies only the scoped `leoclean_kb_runtime` credential.
- Leo reads canonical knowledge and stages proposals only through
`kb_stage.stage_leoclean_proposal(...)`.
- Telegram delivery terminates at the verified GCP service.
- The protected Observatory remains a separate follow-up surface over
canonical, proposal, vector, and runtime receipts.
## Current state
- Current main/base: `3569f4f2fb016e36f5ebeb27f01f3af91e1c360f`.
- PRs #220, #221, #226, #227, and #228 are merged. Main therefore contains the
source-first V3 rebuild foundation, the PostgreSQL large-object boundary,
bounded Observatory prerequisite preservation, Cloud SQL provider-database
residual handling, and the manual exact-revision no-send publication
workflow.
- A narrow current-main correction is in progress so rerunning
`scripts/kb_apply_prereqs.sql` preserves only the exact scoped runtime and
proposal-owner ACLs created by `ops/gcp_leoclean_runtime_role.sql` on the
prerequisite's protected table/column surface. Broader grants on that
surface and direct role membership continue to fail closed; the runtime
provisioner and verifier remain authoritative for role attributes, schema
privileges, routines, and the complete least-privilege posture.
- Local evidence for that correction: 230 focused tests passed; the
digest-pinned, network-disabled PostgreSQL 16.14 lifecycle canary passed;
two prerequisite reruns were stable; injected ACL and membership drift
failed closed; Ruff and `git diff --check` passed.
- The GCP VM, private Cloud SQL instance, and scoped Secret Manager secret are
known to exist, but no new current-main no-send image has yet been published
by the merged #228 workflow.
- Live Cloud SQL provisioning of `leoclean_kb_runtime`, VM access to the scoped
secret, installation of the no-send service, effective running-process
identity, restart behavior, and rollback remain unproven.
- The source-first V3 reconstruction code is on main, but no canonical GCP
promotion is implied by that merge.
- Telegram still does not route to GCP. The VPS, production traffic, and
canonical proposal approvals remain untouched.
## Execution order
1. Review and merge the narrow PostgreSQL migration-order/composability
correction from current main.
2. Run the merged GCP preflight against that exact main revision, then manually
dispatch #228's publication workflow for the same revision. Verify the
resulting immutable image/config digests and publication receipt.
3. Provision `leoclean_kb_runtime`, grant only the staging VM access to the
scoped secret, and prove the Cloud SQL role's allowed reads and
function-only proposal staging plus denied writes and escalation.
4. Install the exact immutable image as a separate no-send GCP service. Prove
the running process uses the scoped identity without administrator fallback,
then prove restart and rollback.
5. Reconstruct or reconcile the V3 knowledge database into a separately
identified canonical candidate and prove row/hash/source receipts before
any promotion.
6. Bind the GCP runtime to the verified V3 canonical database and run database
and behavioral parity checks without Telegram sends.
7. Switch Telegram delivery to the GCP service only after a separate human
authorization, prove real response receipts, soak, restart, and restore
behavior, and retain an immediate rollback path.
8. Revoke obsolete runtime credentials after soak. VPS destruction remains a
separate explicit decision.
## Authority and rollback boundaries
- Database role provisioning can be rolled back independently by refencing
the runtime role and removing its scoped secret access.
- Service deployment can be rolled back independently to the prior immutable
image or stopped without changing canonical data.
- V3 database promotion requires a pre-promotion backup and exact reconciliation
receipt; it does not imply Telegram cutover.
- Telegram routing is the final reversible switch and happens only after the
no-send service, V3 data, restart, and rollback proofs pass.
- Canonical proposal approval, Observatory deployment, vector-backend choice,
and irreversible VPS deletion are not part of the current deployment slice.
## Human gates
The composability correction requires exact-revision database/security review
before merge. GCP role/IAM mutation, V3 canonical promotion, and Telegram
cutover remain distinct critical gates. Evidence from tests or agent review is
advisory; the exact revision and live receipts must be presented to the human
development lead at each gate.
