api: record who requested an admin create by default - #1512
Admin sandbox creates (POST /admin/api/v1/sandboxes) now record the
administrator who submitted them by default. The create operation's payload carries requested_by_user_id, and the admin operations API
(GET /admin/api/v1/operations and /operations/{operation_id}) reports it. actor_user_id stays the sandbox owner, which the executor creates the
sandbox as, so the operations log names the operator the way admin_audit_events already does.
#1303 added the field behind SPACE_ADMIN_CREATE_REQUESTED_BY_ENABLED, off
by default, because cluster controllers from before it reject unknown
create-payload keys (deny_unknown_fields). This keeps the switch and turns
it on by default: unset means on, and 0, false, no, off or disabled, in any case, turns it off. It is read with env_flag_var and a true default, the same parser and vocabulary as the API's other switches,
so any other value also keeps it on. Its constant doc,
its row in docs/configuration.md, and the admin OpenAPI description of requested_by_user_id say so. No chart or Kind values set it.
Off, admin creates go in without the field, as before #1303, and report no
requester. Turn it off in the two cases where a controller older than #1303
could claim an admin create: an upgrade from a release before #1303, and a
controller rollback below it; see Rollout.
An earlier revision of this PR removed the switch, and its description said
so. Review pointed out that this left no API-side way to withhold the field
during an out-of-order deploy or a controller rollback below #1303, so the
switch stays.
Validation
routes::admin::sandboxes::tests::an_admin_create_reports_its_requester_apart_from_the_owner
runs in its own test process with SPACE_ADMIN_CREATE_REQUESTED_BY_ENABLED
unset (pplx_space_test_env::enter_test_process, as the placement-gate
test does). It drives the admin create handler as a managing-org
administrator, then checks that both admin operation reads report the
owner as actor_user_id and the administrator as requested_by_user_id.
It also queues a create_sandbox operation without the field, as an older
API release did, and checks that both reads report requested_by_user_id: null for it. With the switch's default changed to off, it fails
(left: [.., None], right: [.., Some(UserId(..))]).
routes::admin::sandboxes::tests::an_admin_create_with_the_requester_switch_off_reports_none
runs in its own test process with the switch set to Off and checks that
both reads report the owner and no requester. With the handler made to
record the requester regardless of the switch, it fails
(left: [.., Some(UserId(..))], right: [.., None]).
cargo fmt --check; cargo clippy -p pplx-space-api --all-targets --all-features -- -D warnings; cargo nextest run -p pplx-space-api --all-features: 2536 passed. cargo arch against main's baseline and ARCHITECTURE.toml: 0 required
findings, and the 1 advisory finding main also reports (run on the
earlier revision; not rerun for the switch).
The Kind and console runs below used the earlier revision, which always
recorded the requester. That is what this revision does with the switch
unset, as Kind leaves it; they were not rerun.
Kind, with the API and cluster controller from this head and the console
from main. The same synthetic admin create into a seeded tenant org
reported requested_by_user_id: null on main and the operator's ID here. actor_user_id was the owner both times, and the create ran to succeeded
(api-before-after.md).
Console verification loop (scripts/console-loop/). The full run at this
head was compared with a main baseline over routes,sandboxes: 47 steps,
0 resolved, 0 not covered. The sandbox steps show the same events as main, which are the snapshots and deleted-sandbox 404s.
The compare flags 2 new signatures, both from org-detail-unknown. That
step is in the orgs tag the baseline did not run. It opens a
deliberately nonexistent organization and passes on the 404s it expects.
No organization code changes here (compare.md).
No console route renders requested_by_user_id, so the pages look the same:
Not validated: a mixed-version stack with a cluster controller older than #1303, whose rejection of the field the existing create_payload_without_a_requester_is_wire_compatible_with_old_shape test
models.
Severity and risk
Severity: low. Without this change, the operations log shows no requester
for admin creates unless an operator turned the switch on.
Risk: with the switch on, an admin create fails if a cluster controller
older than #1303 claims it; turning the switch off avoids that. Public, ECW
and E2B creates are unaffected; they never carry the field.
Rollout
The switch is on by default, so admin creates record the operator. With it
on, every space-cluster-controller replica must run a release with #1303
(e083c94) or later; an older controller rejects the create payload and the
admin create fails. Roll the controllers first, or confirm they already run
such a release.
The API does not check controller versions, and the chart rolls the API and
the controllers out together. So when upgrading from a release before #1303,
turn the switch off (SPACE_ADMIN_CREATE_REQUESTED_BY_ENABLED=false on the
API) for that upgrade, and turn it back on, or unset it, once every controller
replica runs this release. A deployment whose controllers already run #1303 or
later needs no setting.
New API with the switch off, any controller: admin creates go in without
the field, as today.
Old API, any controller: admin creates go in without the field, as today.
The admin operations API reports requested_by_user_id: null for them.
The console does not read the field, so console and API can roll in
either order.
Rollback:
Rolling the API back is safe. New admin creates go back to carrying no
requester unless the old release has the switch on. Already-queued creates
keep the field, and every controller with api: close six admin API gaps the admin console works around #1303 or later accepts them.
Rolling a controller back below api: close six admin API gaps the admin console works around #1303 is not safe while admin creates that
carry the field are queued or retrying. That controller rejects them.
First turn the switch off on every API replica, or roll the API back. A
replica reads the switch from its environment, so one started with it on
keeps sending the field until it exits, shutdown drain included. Wait until
every such replica has exited, then until the queued admin creates have
finished, and only then roll the controller back.
AI assistance: Claude Code drafted the code change, the test and this
description; a human reviews before submission.
Why: Admin creates can fail during an upgrade if the API starts sending requester data before all controllers support it. Ensure the documented controller-first rollout or disable the setting for that upgrade before merging.

Walkthrough
The admin requester setting now defaults to enabled and accepts specified case-insensitive opt-out values. API documentation describes when requested_by_user_id is null. Configuration guidance documents upgrade and rollback requirements. Handler tests check requester and actor values in fetched and listed operation records.
Merge Risk: Moderate · up to 1c328
Admin creates can fail during an upgrade if the API starts sending requester data before all controllers support it. Ensure the documented controller-first rollout or disable the setting for that upgrade before merging.
Security architecture risk: Low · up to 1c328
Requester attribution remains separate from execution authority, and the inspected paths retain administrator authorization. The main risk is deployment compatibility: older controllers reject the requester field, so affected upgrades and rollbacks require explicit opt-out and draining existing work.
Retained concerns
Medium · reliability · inferred: Default-on recording makes ordinary admin creates incompatible with pre-api: close six admin API gaps the admin console works around #1303 controllers unless operators explicitly opt out. During downgrade, opt-out alone is insufficient because queued payloads retain the field; enabled API replicas must exit and field-bearing creates must finish first. The PR documents this mitigation, but compatibility remains operationally enforced. This worsens default mixed-version exposure relative to the base and constrains rollback, without establishing an authorization bypass.
Security review details
Security Blast Radius
inferred — The changed default affects administrator-submitted creates across target organizations served by the deployment and persists the submitting administrator's identifier in their operation records. The inspected execution path retains target-owner authority; the supported compatibility failure concerns admin creates consumed by old controllers, not newly gained tenant privileges.
Trust Boundaries and Controls
observed — Requester identity crosses from authenticated administrator context into durable attribution metadata, not into execution credentials. Administrator authorization gates submission and reads, owner membership is checked against the target organization, and the executor uses actor_user_id for creation.
Resilience and Maintainability Implications
inferred — The retained opt-out and explicit drain sequence provide a rollback procedure, but not automatic recovery for incompatible queued payloads. The current executor treats invalid payloads as terminal invalid requests; the exact historical controller disposition remains unverified.

Explanation
The pull request changes application behavior under crates/: the requester switch default changes from false to true. The Validation section names an_admin_create_reports_its_requester_apart_from_the_owner and an_admin_create_with_the_requester_switch_off_reports_none, and states that each fails without the fix and passes with it. The changed tests verify both default-on and switch-off behavior.

Explanation
No unjustified safeguard weakening is present. The diff changes no CI, lint, allowlist, baseline, or nextest guard. The existing requester test is expanded into handler-based coverage, with equivalent fetched and listed-operation assertions, plus a separate switch-off test. The new early returns apply only when process-environment isolation or the optional test database is unavailable; the PR description gives those reasons.

Keep SPACE_ADMIN_CREATE_REQUESTED_BY_ENABLED instead of removing it, but
turn it on by default, so admin creates record the operator in the create
payload's requested_by_user_id. 0, false, no, off or disabled, in any case,
turns it off; unset or any other value keeps it on.
Removing the switch left no API-side way to withhold the field from a
space-cluster-controller older than #1303 (e083c94), whose
deny_unknown_fields then fails every admin create. Turn it off for an
out-of-order deploy, where an API with this change serves admin creates
before every controller replica runs #1303 or later, and before rolling a
controller back below #1303, letting queued admin creates finish first.
The requester test now pins the switch unset in its own test process, and a
new test turns it off and checks that both admin operation reads report no
requester.

Controllers before #1303 reject the field and the API does not check
their version. The chart rolls the API and the controllers out together,
so an upgrade from a release before #1303 turns the switch off for that
upgrade and on again once every controller runs this release. A rollback
below #1303 turns it off first.

Approving. This keeps requester attribution on by default while restoring the off switch for older controllers. The authenticated administrator stays separate from the sandbox owner, and retries keep the original requester. I checked the default-on and explicit-off test results at this head; both passed, along with the smoke-test shards and aggregate CI check.
For upgrades from before #1303, keep the switch off until every controller is compatible. Before rolling controllers back, wait for the API replicas that had it on to exit, then drain their queued creates.

An earlier revision of this PR removed the switch, and its description said

Severity and risk
Severity: low. Without this change, the operations log shows no requester

Risk: with the switch on, an admin create fails if a cluster controller

Rollout
The switch is on by default, so admin creates record the operator. With it
on, every

admin create fails. Roll the controllers first, or confirm they already run

the controllers out together. So when upgrading from a release before #1303,
turn the switch off (
SPACE_ADMIN_CREATE_REQUESTED_BY_ENABLED=falseon theAPI) for that upgrade, and turn it back on, or unset it, once every controller
replica runs this release. A deployment whose controllers already run #1303 or
