[events] carry a transition's cleanup state apart from its lifecycle - #1560
Merging this adds from_cleanup_state/to_cleanup_state to sandbox events (none, required, failed, or unknown for a label the emitter can't parse). Sandbox-manager sets each with its status label through with_from_status/with_to_status, so the pair always describes one status. from_state/to_state keep today's values.
Validation
Tests: transition_cleanup_states_reach_the_emitted_event, status_event_details_carry_the_cleanup_each_status_folds_in and store_writer_events_carry_the_cleanup_state_beside_the_status (a store writer's cleanup_failed events).
An events-crate test checks the fields reach the emitted event; a store test checks the helper sets both fields.
Locally: rustfmt --check on every changed Rust file. Rust was not compiled locally, so CI on this head is the build and test evidence.

Severity and risk
Severity: does not apply.
Risk: two more fields on sandbox events. Roll back by reverting.
Stack
Part of a stack that moves CleanupRequired and CleanupFailed out of the sandbox lifecycle into their own cleanup state. Merge in order; this PR depends on #1559.
Each PR keeps today's published behaviour; only the last adds a switch, off by default, that publishes the lifecycle under a cleanup.
AI assistance: an AI coding agent drafted the code, tests and this description; the author reviewed them, and a second AI agent reviewed the change. Perplexity Computer rebased the stack, repaired integration conflicts, restored a test assertion in #1553, and updated this disclosure.
No actionable comments were generated in the recent review.
Walkthrough
Sandbox transition events now include cleanup-state fields alongside lifecycle-state fields. SandboxStatusEventDetails derives cleanup labels from typed sandbox statuses. Storage and sandbox-manager event call sites use typed statuses to populate transition details. Tests verify cleanup-state values in emitted events and status details.
Possibly related issues
perplexityai/SPACE#616 — Cleanup-state information in transition events can contribute to records of sandbox operations and failures. The change does not establish record completeness or integrity.
Possibly related PRs
perplexityai/SPACE#1555 — Separates cleanup ownership from lifecycle state; this PR reports both values in transition events.
Merge Risk: Moderate · up to 75e7f
Sandbox events gain cleanup fields across several services. The change is tested, but its shared event contract warrants validation before merge.
Security architecture risk: Low · up to 75e7f
The inspected changes add cleanup metadata without changing sandbox permissions, cleanup ownership, or lifecycle transition rules. No introduced security issue was established. Compatibility with external event consumers remains unverified, so the change is not assessed as risk-free.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
observed — The serialization change is shared beyond sandbox-manager: the API, internal API, cluster controller, and node manager also use the event package. Their existing producers need not populate the new cleanup values, but the shared emission macro adds the attributes to the event shape.
Security Findings and Attack Paths
inferred — No new attacker-to-privileged-operation path was established in the inspected change. Production cleanup values derive from existing sandbox statuses, and the changed boundary emits metadata through the existing event path rather than introducing a request route or execution decision. This does not establish the behavior of unavailable external consumers.
Trust Boundaries and Controls
observed — Cleanup-state strings describe existing status; they do not grant cleanup ownership. The inspected cleanup writers retain their database predicates, quarantine guard, and transaction boundaries. Public string setters permit arbitrary metadata construction, so these fields alone are not an authorization or ownership proof.

crates/l30_storage/sbx/mgr/store/src/db.rs:428-438: no test covers the cleanup fields on the store's writer events. That includes the only site that can emit unknown.
What's covered: every store writer's event goes through emit_sandbox_state_event, but the tests cover only the events macro and the SandboxStatusEventDetails helper. No store test captures an event.
What I ran: I added a capture test in my tree (it needs tracing-subscriber as a store dev-dependency). Each of these passed every existing test and failed only mine:
map_or("unknown", …) changed to "none";
.from_cleanup_state(…) dropped;
with_to_status changed back to with_to_state.
Suggested fix: a store test capturing events from mark_cleanup_failed on a plain row, from a required-to-failed write, and from one unparseable from_state.
Low
The PR description has no event-field note. The events crate's AGENTS.md asks a new detail field to keep "the PR description's event table and coverage notes aligned".
Verified against edfa477ca6e4a9746bac4648882a745b01fe5b30.
Mutations: the macro dropping from_cleanup_state fails the events test; event_cleanup_state always returning none fails the state test.
Targeted nextest over the events crate, the store's state module and the touched sbx-mgr service modules: everything in the PR passes.
What I read:
from_state comes from current_state_label (SELECT legacy_state), read before the UPDATE on the same connection. The to_ pair comes from the target status the writer passes. So events carry the captured status, not a re-read.
unknown is emitted only when that label can't be parsed.
Every sbx-mgr with_from_state/with_to_state call was converted.
The existing from_state/to_state strings are unchanged.
The README and tests are updated, as the crate's AGENTS.md asks.
Not checked: downstream consumers of the new fields.
Thanks @the-gigi-pplx. Rebased the stack on main (47f3aa39); this PR's head is now aaa20755ba1c.
Store writer events. Added store_writer_events_carry_the_cleanup_state_beside_the_status in the server's tests. It reuses the existing SandboxEventCapture subscriber rather than adding tracing-subscriber to the store, and drives the store's own mark_cleanup_failed. A plain stop's first failure gives stopping/none → cleanup_failed/failed, and a required cleanup that fails gives cleanup_required/required → cleanup_failed/failed. I didn't add the unknown case: I couldn't find a writer that reaches emit_sandbox_state_event with an unparseable label without contriving the row.
Event table. Added a field table to the description.

Sandbox-manager events report a cleanup that owns a sandbox as the
cleanup_required or cleanup_failed lifecycle in from_state/to_state. Before
those fields can carry the lifecycle under the cleanup, consumers need the
cleanup reported on its own.
Add from_cleanup_state/to_cleanup_state (none, required, failed, or unknown
for a label the emitter cannot parse). Sandbox-manager sets each with its
status label through with_from_status/with_to_status, so the pair always
describes one status. from_state/to_state keep today's values.
