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.

Walkthrough

Published sandbox statuses are parsed as recognized lifecycle values or trimmed unrecognized text. Server publication handling and SQL transition checks now use the canonical lifecycle value. The changes also add unit and integration tests for ASCII case and whitespace variants, unknown values, Unicode spellings, and lifecycle transition paths.

Possibly related PRs

• perplexityai/SPACE#1411: It contains the same status parsing and exact lifecycle comparison changes.
• perplexityai/SPACE#1399: It changes the activation-completion receipt path, which overlaps with receipt predicates changed here.

Merge Risk: Moderate · up to 4ddee

Non-ASCII statuses can no longer trigger lifecycle or failure-episode transitions and can clear an open failure episode. The changed behavior is tested, but its persistence impact should be explicitly accepted before merging.

Security architecture risk: Low · up to 4ddee

The change makes lifecycle decisions consistent without an identified expansion of publisher authority. The design appears contained, but malformed-input recovery and mixed-version behavior have not been validated in a running deployment.

No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The independently attackable scope of a malicious publisher is not necessarily one sandbox or tenant: the relevant ownership boundary is the authenticated node’s sandbox assignments. Examined lifecycle writes require active_node_id, while failure-facet writes use current direct-route ownership with active-node fallback. Changing status interpretation does not itself extend those writes to arbitrary cluster rows.

Security Findings and Attack Paths

• inferred — No introduced attack path was established in the examined lifecycle flow. An unrecognized status cannot complete a target-matched receipt. Although newly unrecognized non-ASCII spellings can clear failure episodes, the base already allowed other non-failed or unknown labels to clear them, so that behavior does not grant a compromised publisher new authority. This conclusion does not resolve the broader security coverage gap.

Trust Boundaries and Controls

• observed — The caller resolves the authenticated node origin before passing its identity into publication. The changed SQL predicates retain node ownership and existing receipt, execution, quarantine, and stored-lifecycle restrictions; canonicalization replaces the status operand rather than removing those controls.

Resilience and Maintainability Implications

• inferred — Publication database mutations remain within the caller-owned transaction, with errors propagated before commit. Existing failure-episode upserts suppress unchanged payload rewrites, and activation release requires an outstanding matching attempt, limiting repeated effects. The change does not introduce a separate commit boundary. Interruption, concurrent ownership changes, and recovery were assessed from source predicates rather than executed fault scenarios.
