# Session 0044.0 — Transcript
|
||||||
|
|
||||||
|
> Date: 2026-05-29
|
||||||
|
> Goal: Isolate this machine's multiple Google Cloud stacks so OHM/flotilla
|
||||||
|
> gestures can never accidentally drive the wrong account/project — first as
|
||||||
|
> operator discipline (a named gcloud config + CLAUDE.md instructions), then
|
||||||
|
> as an enforced guard in flotilla itself.
|
||||||
|
>
|
||||||
|
> Outcome: **Shipped flotilla v1.4.0 (gcloud config guard).** Created an
|
||||||
|
> inactive `wiggleverse` gcloud config; added the `CLOUDSDK_ACTIVE_CONFIG_NAME`
|
||||||
|
> discipline to CLAUDE.md; added a per-deployment `gcloud_config` record field
|
||||||
|
> (migration 006) + `ohm_rfc_app_flotilla/gcloud.py` guard enforced at both
|
||||||
|
> `run_deploy` entry and `ssh.run_remote`; set the live OHM record to
|
||||||
|
> `gcloud_config=wiggleverse`. 214 tests pass. Merged to main, tagged v1.4.0,
|
||||||
|
> pushed. No OHM app redeploy (operator-tool code only).
|
||||||
|
>
|
||||||
|
> Highlights / §19.2 candidates surfaced:
|
||||||
|
> - flotilla relies on env *inheritance* for the config pin — it doesn't set
|
||||||
|
> `CLOUDSDK_ACTIVE_CONFIG_NAME` itself. Candidate: have it assert-or-set.
|
||||||
|
> - `gcloud compute ssh` pins `--project` but not `--account`. Candidate:
|
||||||
|
> store the operator account in the record and pass `--account` too.
|
||||||
|
> - Secret Manager calls use ADC, which `CLOUDSDK_ACTIVE_CONFIG_NAME` does not
|
||||||
|
> select — the guard is scoped to the gcloud-subprocess path by design.

## Pre-session state
|
||||||
|
|
||||||
|
- **flotilla** (`ohm-rfc-app-flotilla`): `main` at `242bb3a` (= `origin/main`),
|
||||||
|
last release tag `v1.3.0` (`fb9bd04`). Working tree clean. 203 tests green.
|
||||||
|
- **OHM live**: unchanged this session — no deploy performed. The local
|
||||||
|
deployment record (`~/.ohm-rfc-app-flotilla`) had one row, `ohm-rfc-app`,
|
||||||
|
`target_vm_project=wiggleverse-ohm`, `gcloud_config=NULL` (column did not
|
||||||
|
exist yet).
|
||||||
|
- **gcloud configs on the machine** at open:
|
||||||
|
- `benstull-infra` (ACTIVE) → `ben.stull@wiggleverse.org` / `wiggleverse-ohm`
|
||||||
|
- `benstullbets` → `ben.stull@benstullbets.com` / `benstullbets`
|
||||||
|
- `default` → `ben@wiggleverse.org` / `wiggleverse-rfc`
|
||||||
|
- **In-flight sessions** per the shared repo at claim time: `0026.0` and
|
||||||
|
`0027.0` (both `--INPROGRESS` from 2026-05-28T13-46, ~18h stale; neither
|
||||||
|
touches flotilla, so the shared checkout was safe to work in directly).
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Turn-by-turn arc
|
||||||
|
|
||||||
|
### Arc 1 — The original ask: a named config + instruction discipline
|
||||||
|
|
||||||
|
The operator runs more than one Google Cloud stack on this machine and wanted
|
||||||
|
process-scoped isolation: always select the config via
|
||||||
|
`CLOUDSDK_ACTIVE_CONFIG_NAME=xyz` (which never touches the shared on-disk
|
||||||
|
active-config pointer) plus belt-and-suspenders explicit `--project`/`--account`.
|
||||||
|
|
||||||
|
Inspected the existing configs/accounts and how flotilla invokes gcloud:
|
||||||
|
`ssh.py` already passes `--project` from the deployment record; Secret Manager
|
||||||
|
uses ADC; nothing pinned the account or a config. So the env-var discipline was
|
||||||
|
exactly the missing identity pin.
|
||||||
|
|
||||||
|
The two named stacks didn't map cleanly to the existing config names, so I
|
||||||
|
asked the operator (AskUserQuestion) for the account+project mapping per config.
|
||||||
|
Answers: **wiggleverse** → `ben.stull@wiggleverse.org` / `wiggleverse-ohm`;
|
||||||
|
**benstull** → *"don't worry about this one — I'm setting it up in a different
|
||||||
|
session."* So this session created only the `wiggleverse` config.
|
||||||
|
|
||||||
|
Created it inactive and populated it without disturbing the active pointer:
|
||||||
|
```
|
||||||
|
gcloud config configurations create wiggleverse --no-activate
|
||||||
|
CLOUDSDK_ACTIVE_CONFIG_NAME=wiggleverse gcloud config set account ben.stull@wiggleverse.org
|
||||||
|
CLOUDSDK_ACTIVE_CONFIG_NAME=wiggleverse gcloud config set project wiggleverse-ohm
|
||||||
|
CLOUDSDK_ACTIVE_CONFIG_NAME=wiggleverse gcloud config set disable_usage_reporting true
|
||||||
|
```
|
||||||
|
Verified `benstull-infra` stayed `IS_ACTIVE=True`. Added an "Always pin the
|
||||||
|
gcloud config" section to `CLAUDE.md` codifying the discipline (env var on
|
||||||
|
every gcloud call and on `flotilla` invocations so subprocesses inherit it;
|
||||||
|
hard "never mutate the shared active config" rule; read-back + `--no-activate`
|
||||||
|
escape hatches). Did **not** rewrite the operator-guide's many gcloud commands
|
||||||
|
(they already pin `--project`); flagged that as optional.
|
||||||
|
|
||||||
|
### Arc 2 — The operator opted into the enforced guard
|
||||||
|
|
||||||
|
I noted flotilla doesn't *assert* the config, only inherits it, and offered a
|
||||||
|
code-level guard. Operator: **"yes."**
|
||||||
|
|
||||||
|
Key design decision (two-layer rule): the config name `wiggleverse` is an
|
||||||
|
OHM-specific value, so it must live in the §13 deployment record, **not** be
|
||||||
|
hardcoded in the CLI. Implementation:
|
||||||
|
|
||||||
|
- **Migration `006_gcloud_config.sql`** — nullable `gcloud_config TEXT` on
|
||||||
|
`deployments`. `NULL` = guard off (backward compatible; generic /
|
||||||
|
flotilla-core deployments unaffected).
|
||||||
|
- **`ohm_rfc_app_flotilla/gcloud.py`** — `check_active_config(expected, env)`:
|
||||||
|
no-op when `expected` falsy; else raises `GcloudConfigError` (with the exact
|
||||||
|
`CLOUDSDK_ACTIVE_CONFIG_NAME=<name> <command>` remediation) on mismatch *or
|
||||||
|
unset*. Failing on unset is deliberate — forces the explicit per-process pin.
|
||||||
|
- **Two-layer enforcement**: `run_deploy` checks at gesture entry (before a
|
||||||
|
`deploys` row opens → clean refusal, no orphan row) and re-raises as
|
||||||
|
`DeployError`; `ssh.run_remote` re-checks per call (the literal
|
||||||
|
`gcloud compute ssh` chokepoint) via a new `gcloud_config` field on
|
||||||
|
`SshTarget`. `--dry-run` (which goes through `assemble_plan`, not
|
||||||
|
`run_deploy`) stays unguarded.
|
||||||
|
- **registry**: `Deployment.gcloud_config` field, row mapping, `add_deployment`
|
||||||
|
param, `UPDATABLE_FIELDS`. **cli**: `deployment add/update --gcloud-config`
|
||||||
|
(empty string clears to NULL), and `gcloud_config` added to `deployment show`.
|
||||||
|
|
||||||
|
Micro-corrections mid-flight (honest record):
|
||||||
|
- Importing the `gcloud` module into `ssh.py` and `deploy.py` shadowed local
|
||||||
|
variables named `gcloud` (the gcloud *binary* path). Renamed those locals to
|
||||||
|
`gcloud_bin` in both files.
|
||||||
|
- Initially numbered the new SPEC section §11.5 — but §11.5 is already the
|
||||||
|
v1.3.0 webhook-reads boundary. Renumbered the guard to **§11.6** across code
|
||||||
|
comments, the migration, and SPEC; left the genuine webhook §11.5 refs alone.
|
||||||
|
|
||||||
|
Tests: new `tests/test_gcloud.py` (5), plus guard cases in `test_ssh.py`,
|
||||||
|
`test_deployment.py`, and `test_deploy.py` (refuse-before-row-opens +
|
||||||
|
proceed-when-matches). Full suite **214 passed**. CLI smoke test on a fresh
|
||||||
|
temp DB confirmed add/show/update-clear round-trips.
|
||||||
|
|
||||||
|
### Arc 3 — Coherence, live record, release
|
||||||
|
|
||||||
|
- **SPEC**: §5.5 (record field), §11.6 (the guard mechanism + ADC caveat +
|
||||||
|
belt-and-suspenders framing), §13.9 (`gcloud_config: wiggleverse` for OHM),
|
||||||
|
and the §12 verb-surface line.
|
||||||
|
- **CHANGELOG** 1.4.0 with an RFC-2119 upgrade-steps block; **VERSION** +
|
||||||
|
**pyproject** → 1.4.0; **register-ohm.sh** now sets `--gcloud-config
|
||||||
|
wiggleverse` on bring-up; **operator-guide** got a §11.6 callout box.
|
||||||
|
- **Live OHM record**: `deployment update ohm-rfc-app --gcloud-config
|
||||||
|
wiggleverse` (migration 006 applied automatically on the read). The guard is
|
||||||
|
now active for OHM — future deploys MUST be prefixed.
|
||||||
|
- **Release**: branched `session-0044/flotilla-gcloud-config-guard`, committed,
|
||||||
|
fast-forwarded `main`, tagged `v1.4.0`, pushed main + tag + branch to origin.

|
||||||
|
| flotilla | `5f1689f` on `main` (= `origin/main`), tag **`v1.4.0`**; branch `session-0044/flotilla-gcloud-config-guard` also pushed |

| OHM live | **unchanged** — no deploy this session; still on its prior `deploys.id`/version |
|

|
| gcloud configs | added inactive `wiggleverse` (`ben.stull@wiggleverse.org` / `wiggleverse-ohm`); shared active pointer untouched (`benstull-infra`) |

|

|
| Ledger | Status |
|
||||||
|
| --- | --- |
|
||||||
|
| gcloud config isolation — named config + CLAUDE.md discipline | ✅ shipped |
|
||||||
|
| flotilla gcloud-config guard (v1.4.0) | ✅ shipped (merged, tagged, pushed) |
|
||||||
|
| `benstull` gcloud config | ⏸ deferred — operator handling in a separate session |
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## §19.2 candidates surfaced
|
||||||
|
|
||||||
|
1. **flotilla self-asserting vs. self-setting the config.** The guard relies on
|
||||||
|
the *parent* process exporting `CLOUDSDK_ACTIVE_CONFIG_NAME` (gcloud
|
||||||
|
subprocesses inherit it). flotilla could instead *set* it from the record
|
||||||
|
when it shells out — but that would mask the guard's intent (the point is to
|
||||||
|
force the operator/assistant to be explicit). Worth a deliberate call.
|
||||||
|
2. **`--account` pin on `gcloud compute ssh`.** Today only `--project` is
|
||||||
|
passed; the config name carries the account. Storing the operator account in
|
||||||
|
the record and passing `--account` would be true belt-and-suspenders.
|
||||||
|
3. **ADC identity isolation.** `secret set`/`bind` and deploy-time secret reads
|
||||||
|
use ADC, which `CLOUDSDK_ACTIVE_CONFIG_NAME` does not select. If multi-stack
|
||||||
|
ADC ever becomes a real hazard, that needs its own mechanism; for now the
|
||||||
|
project is always passed explicitly on Secret Manager calls.
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## What lands on the operator's plate
|
||||||
|
|
||||||
|
1. **Set up the `benstull` gcloud config** in the other session (deferred here
|
||||||
|
by operator request). Mirror the gesture used for `wiggleverse`:
|
||||||
|
`gcloud config configurations create benstull --no-activate` then populate
|
||||||
|
with env-scoped `gcloud config set …`.
|
||||||
|
2. **Every OHM deploy/ssh gesture now MUST be prefixed**
|
||||||
|
`CLOUDSDK_ACTIVE_CONFIG_NAME=wiggleverse …`, or it refuses fast (no orphan
|
||||||
|
`deploys` row). This is the intended behavior, but it changes the muscle
|
||||||
|
memory.
|
||||||
|
3. (Optional) Wire a Claude Code `SessionStart`/env hook to export the var for
|
||||||
|
OHM sessions automatically, if hand-prefixing proves annoying.

||||||

## Prompt the operator can paste into the next Claude Code session
|
||||||
|
|
||||||
|
```
|
||||||
|
You're an OHM driver session anchored in ohm-rfc-app-flotilla. Claim your own
|
||||||
|
session ID first (~/git/ohm-infra/scripts/claim-session-id.sh --start <now>);
|
||||||
|
the number in this prompt is advisory.
|
||||||
|
|
||||||
|
Context from session 0044: flotilla v1.4.0 shipped a gcloud config guard.
|
||||||
|
The OHM deployment record now carries gcloud_config=wiggleverse, so EVERY
|
||||||
|
deploy/ssh gesture against OHM must be prefixed
|
||||||
|
CLOUDSDK_ACTIVE_CONFIG_NAME=wiggleverse — otherwise flotilla refuses before
|
||||||
|
opening a deploys row. An inactive `wiggleverse` gcloud config
|
||||||
|
(ben.stull@wiggleverse.org / wiggleverse-ohm) exists; the shared on-disk active
|
||||||
|
pointer (benstull-infra) was left untouched. flotilla is at main=5f1689f, tag
|
||||||
|
v1.4.0, pushed to origin. 214 tests green. No OHM app redeploy was needed.
|
||||||
|
|
||||||
|
Open items you might pick up:
|
||||||
|
- The `benstull` gcloud config still needs creating (operator was handling it
|
||||||
|
separately — confirm before assuming it's done).
|
||||||
|
- §19.2 candidates from 0044: (a) should flotilla self-set CLOUDSDK_ACTIVE_
|
||||||
|
CONFIG_NAME rather than only assert it? (b) pin --account on gcloud compute
|
||||||
|
ssh, not just --project? (c) ADC identity isolation for Secret Manager calls.
|
||||||
|
- Otherwise consult /Users/benstull/projects/wiggleverse/ohm-rfc/ROADMAP.md for
|
||||||
|
the next substantive item.
|
||||||
|
|
||||||
|
Don't paste secret bytes into the conversation (SPEC §3 invariant 1 / CLAUDE.md).

## Launch prompt
|
|
||||||
|
|
||||||
```
|
|
||||||
I have other Google Cloud stuff happening on this machine. Let's create an inactive config for each GCP stack (benstull, wiggleverse) and update our instructions so that when we use GCP, it's always with CLOUDSDK_ACTIVE_CONFIG_NAME=xyz (plus explicit --project/--account flags as a belt-and-suspenders). That env var selects the config for that one process only — it never touches the on-disk "active config" pointer your other terminals read.
