Summary

Narrow behaviour change. Node-publication ingest read PublishedSandboxState.status two ways. The Rust paths (transition-receipt check, quarantined report, state_changed_at check, the projection prefilters) trimmed it and compared it ignoring ASCII case. Ten SQL statements applied LOWER(TRIM(..)) under the database collation. Under a libc UTF-8 collation such as the test fixture's en_US.utf8, LOWER('FAİLED') = 'failed'. So a node publishing "FAİLED" moved a k8s row to failed and opened a failure episode, while the Rust paths treated the same text as unknown. A Turkish-collated database would lower-case plain FAILED differently again.

The status is now parsed once per published state into PublishedStatus: Known(StoredSandboxLifecycle) after trimming and ASCII case folding, or Unrecognized(String). Every Rust decision reads it. Every ingest statement compares the canonical published_lifecycle that the publish path now serializes (NULL when absent or unrecognized), instead of normalizing the status text. The database collation no longer decides what a node reported.

Changed outcome: a non-ASCII status such as "FAİLED" is unrecognized, so it no longer fails a row or opens a failure episode. Current nodes publish only enum labels, so this needs a non-SPACE or faulty publisher. ASCII spellings reach the same decisions as before.

Unchanged:

• the trimmed original spelling written to sandbox_observed_states.status;
• the stored-column LOWER(TRIM(s.lifecycle)) checks, which wait on a census of stored values;
• the three non-canonical stored-lifecycle rows from test: one stored-lifecycle matrix for the sandbox row writers #695.

Adds SandboxTransitionTargetState::lifecycle() for the receipt check.

sql! text changes (recordset column status → published_lifecycle, and LOWER(TRIM(input.status)) → input.published_lifecycle):

• published_state.rs: failure-episode insert, failure-episode clear, local-suspend handoff (adds the column; WHERE input.status IS NOT NULL is kept)
• ingest.rs: TRANSITION_RECEIPT_RECORD_COLUMNS, mark_published_failed, converge_published_restoring_to_started, converge_published_stopped, release_completed_activations
• sandbox_quarantine_store.rs: select_activation_rollback_candidates, recover_pause_failed_from_inventory (SELECT list and WHERE), select_suspended_projection_candidates

Validation

Test expectations:

• Changed: published_status::non_ascii_failed_spelling_is_unrecognized (new). It fails on main (left: "failed", right: "started") and passes here.
• New, equivalence: one Postgres sweep per changed statement (10) over ASCII spellings: canonical, upper, padded with spaces/tabs/CR/LF/FF, and near misses. All 10 pass on main and here. A case-sensitive parse fails all 10.
• New, unit: PublishedStatus parse tests for canonical values, padding, case, blank and unknown strings.
• Fixture key only: published_state_lifecycle_race_tests.rs renames its hand-built JSON key status → published_lifecycle. Expectation unchanged.
• lifecycle_writers.rs and status_tests.rs are unchanged.

Commands at this head:

• cargo fmt --all -- --check, scripts/check-rust-error-policy.sh: pass
• cargo arch (also with main's baseline and architecture files): 0 required findings, no sandbox_writes growth
• cargo clippy --workspace --locked --all-targets --all-features -- -D warnings: pass
• SPACE_CI_REQUIRE_TEST_DEPS=1 cargo nextest run --all-features for common-core, internal-api-server, sandbox-store, placement and every dependent (internal-api-svc, api, template-mgr, build-mgr, cluster-controller-server, snapshot-retention): 4897 of 4899 pass, Postgres required.
  • The other 2 (template-mgr NoCoW tests) need the btrfs fixture and pass under ci/scripts/with-nocow-test-filesystem.sh.
  • 1 #[ignore] benchmark was not run.
• Fresh Kind from this head, SPACE_KIND_TELEMETRY_MODE=otel, CI's admin-token and cold-receipt directories:
  • up.sh 8m24s, every SPACE container at this commit.
  • smoke-kind-typed.sh all 65m55s: ECW 91/91 and native 42/42 passed, 0 failed or inconclusive, no reruns.
  • Includes ecw.cold_create_environment and local.telemetry_reaches_local_backends.
  • 6 console scenarios were skipped (no Playwright); 6 declared-ignored.

Not validated: an end-to-end Kind reproduction. Real nodes cannot publish a non-ASCII status, so only the Postgres test shows it.

Severity and risk

Severity: low. Fixes a collation-dependent disagreement on inputs no SPACE node produces.

Risk: a publisher sending a non-ASCII status no longer gets fail/episode handling where the collation folded it to failed. ASCII behaviour is pinned per statement. Rollback: revert; no migration or schema change.

Rollout

Nothing persisted or on the wire changes. published_lifecycle is built and read inside one internal-api process; nodes and protos are untouched. During a rolling deploy, old and new replicas are each self-consistent and differ only on non-ASCII statuses.

Not covered

Overlaps open #1399 (published_state.rs, sandbox_quarantine_store.rs, ingest.rs; no status-comparison changes), #1204 (status.rs, unchanged here) and #319 (common/core/src/types/sandbox.rs). Expect textual conflicts only.

Why: Lifecycle transitions now depend on a different status-matching predicate. Although the change is intended to reject unrecognized spellings, the write guards warrant validation before merge.

Commit: a89726999999.

Walkthrough

Published sandbox status is parsed into a recognized lifecycle or retained as trimmed, unrecognized text. Publication, receipt validation, failure-episode handling, lifecycle convergence, and quarantine queries use the canonical lifecycle value for comparisons. Ingest statements now compare that value exactly with canonical lifecycle strings or receipt targets. New unit and database tests cover parsing, accepted spellings, rejected spellings, and lifecycle transitions.

Merge Risk: High · up to a8972

Lifecycle transitions now depend on a different status-matching predicate. Although the change is intended to reject unrecognized spellings, the write guards warrant validation before merge.

Security architecture risk: Low · up to a8972

Centralizing lifecycle interpretation removes a database-dependent ambiguity while preserving the inspected ownership and transition checks. No introduced security defect was established. Malformed publishers receive different behavior, and deployment-wide compatibility and tenant-isolation guarantees were not fully established.

Security review details

Security Blast Radius

• observed — The demonstrated lifecycle mutation scope is centrally assigned sandboxes on the publishing node, not an arbitrary sandbox identifier alone. Failure-episode mutations additionally follow current direct-route ownership. The number and tenant distribution of sandboxes assigned to one node were not established, so these predicates do not independently prove tenant confinement.

Security Findings and Attack Paths

• inferred — A publisher controls the submitted status text. The PR removes the path from a non-ASCII spelling such as FAİLED through database case conversion to a failed lifecycle or new failure episode. Unknown status strings already existed as an input class; this narrowing does not demonstrate a newly available bypass for a malicious publisher.

Trust Boundaries and Controls

• observed — The network handler resolves the submitted node identity through authenticated_origin_node_id before publication and passes origin.id into the transaction. Sandbox publication retains worker/builder role restrictions. The inspected identity resolver checks the caller address against the registered node address; these controls are unchanged by this PR.

Resilience and Maintainability Implications

• observed — Activation release continues to require the matching active execution generation and activation attempt, clears that attempt and excludes suspend/hold/delete states from the final lifecycle projection. Its ownership join remains snapshot-based and the final sandbox update does not recheck active_node_id. That documented concurrency limitation predates this PR; the comparison establishes no new caller or weaker fence beyond replacing status normalization with canonical equality.

Explanation

The PR description contains all required sections with real content: ## Summary explains the merge behavior, ## Validation lists commands and results, and ## Severity and risk states low severity and the associated risk. It also includes an AI assistance: line stating that Claude Code wrote the code, tests, and description, with the human-selected behavior identified.

Full details: Bug Fixes Name A Regression Test

Explanation

The pull request fixes application behavior under crates/. Its Validation section names published_status::non_ascii_failed_spelling_is_unrecognized and states that it fails on the base branch and passes with the fix. The changed test covers the FAİLED input and verifies that no failure state or failure episode is created.

Full details: Weakened Safeguards Are Justified

Explanation

The PR does not weaken a safeguard. The diff changes implementation SQL/Rust behavior and renames one fixture JSON field. It deletes no tests or assertions, changes no CI or guard configuration, and adds unit and PostgreSQL tests with assertions. No skip, xfail, ignore, allowlist, baseline, optional-dependency, or lowered-lint change appears in the reviewed diff.

Full details: Public-Safe Content

Explanation

No public-safety violation found. The reviewed diff contains no URLs, workstation paths, cloud ARNs, private-key markers, credential assignments, or internal hostnames. The added IP, pod IDs, and failure text are test fixtures. The title and description contain no credentials, private links, cluster names, incident details, or undisclosed security vulnerability.

Full details: Title check

Explanation

The title uses the bracketed tag "[cr-test]" as a prefix, which the required format does not allow. The area prefix "internal-api:" is lowercase and followed by a colon, and the summary "parse the published sandbox status once at ingest" starts with a lowercase word. The title also ends with a parenthetical clause, but no trailing period, ticket ID, or internal link appears. The title describes the main change: parsing the published sandbox status once, with non-ASCII spellings now unrecognized. The format check fails because of the extra "[cr-test]" tag at the start.

Resolution

Remove the "[cr-test]" prefix so the title starts with the area and colon, for example: "internal-api: parse the published sandbox status once at ingest (narrow behaviour change: non-ASCII spellings are unrecognized)".
