Summary

A single sandboxes row whose stored lifecycle is not canonical text no longer fails a node's whole PublishNodeState. Ingest skips that row, leaves it as stored, and commits the rest of the publication.

Example: a pause-failed quarantined row stored as ' Quarantined'. Pause-failed recovery selects candidates with LOWER(TRIM(s.lifecycle)) = 'quarantined', but the recovery write in pplx_space_sandbox_store::ingest matches lifecycle = 'quarantined' exactly. The row was selected, the write matched nothing, and the publication answered Aborted. That rolled back the node's whole publication, and every later one failed the same way until someone repaired the row. The activation-rollback candidate query had the same shape: it decoded LOWER(TRIM(s.lifecycle)) as a SandboxLifecycle, so a value no lifecycle names, such as bogus (the column has no CHECK), failed the publication with Internal.

Change (sandbox_quarantine_store.rs):

• Pause-failed recovery reads the stored lifecycle with each candidate and skips any row that does not parse as quarantined.
• Activation-rollback candidates read the prior lifecycle as text and omit the receipt of any row whose text names no lifecycle.
• Each skipped row logs a warning with the node and sandbox ids and counts in sandbox.state_publication.degraded with field:stored_lifecycle and disposition skip_pause_failed_recovery (recovery) or omit_transition_receipt (rollback receipt). stored_lifecycle and skip_pause_failed_recovery are new label values in pplx-space-metrics.
• Stored values are not rewritten and the write's predicate is unchanged. Any other miss of the pause-failed write still fails the publication, because that write may have applied in part.

Changed test expectations:

• lifecycle_writers::healthy_report_recovers_only_a_pause_failed_quarantine: stored " Quarantined " now publishes Ok, and the row and its quarantine are unchanged (was: publication Err, rolled back).
• lifecycle_writers::activation_rollback_receipt_converges_its_target_out_of_every_live_lifecycle: stored "bogus" now publishes Ok and the row is unchanged (was: publication Err, rolled back).
• New: published_state::node_publish_recovers_pause_failed_rows_past_a_non_canonical_one publishes a padded and a canonical pause-failed row in one PublishNodeState. The canonical row recovers. The padded row keeps its text and quarantine, and its observation records the published state.

Validation

At this head:

• cargo fmt --all -- --check, scripts/check-rust-error-policy.sh: pass. cargo arch against the base's baseline and ARCHITECTURE.toml: 0 required (pattern_ratchet.sandbox_writes unchanged). cargo clippy --workspace --locked --all-targets --all-features -- -D warnings: pass.
• The three tests above fail on the base (internal-api: parse the published sandbox status once at ingest (narrow behaviour change: non-ASCII spellings are unrecognized) #1411's head) for the expected reasons (Aborted: pause-failed recovery CAS failed, and Internal: ... unknown sandbox lifecycle 'bogus') and pass here.
• SPACE_CI_REQUIRE_TEST_DEPS=1 cargo nextest run --all-features over pplx-space-internal-api-server, pplx-space-sandbox-store, pplx-space-metrics and their 32 direct dependents, Postgres running: 9672 run, 9618 passed, 54 failed, 22 skipped. All 54 are in node/guest crates and need root or the CI btrfs NoCoW fixture. The same 54 fail on the base, and none is in a changed package.
• Fresh Kind cluster from this head (SPACE_KIND_TELEMETRY_MODE=otel infra/space/kind/scripts/up.sh, every SPACE container at this commit), then scripts/tests/smoke-kind-typed.sh all with CI's admin-token file and cold-receipts directory: ECW 91/91 and native 42/42 passed, 0 warned or failed, 1h07m wall (ecw.cold_create_environment and local.telemetry_reaches_local_backends ran).

Not validated: an end-to-end Kind reproduction, which needs a hand-edited sandboxes row; the Postgres tests cover it.

• After the crate layer move (crates: move every crate into its layer directory #1368): rebased onto internal-api: parse the published sandbox status once at ingest (narrow behaviour change: non-ASCII spellings are unrecognized) #1411's moved head c72e0f88 as 813ef1d4. The git range-diff differs only in file paths. cargo fmt, cargo check --workspace --all-targets --all-features, cargo arch and clippy pass, and SPACE_CI_REQUIRE_TEST_DEPS=1 cargo nextest run --all-features -p pplx-space-db-test-fixtures -p pplx-space-sandbox-store -p pplx-space-metrics -p pplx-space-internal-api-server passed 507/507, including the three changed and new tests. The Kind run above was on the pre-move head, whose code is identical.

Severity and risk

Severity: medium. One malformed row could stop a node's state publication indefinitely and leave its whole inventory stale.

Risk: low. Only rows the write could not move are skipped, and they stay as stored, now with a warning and a counter instead of a failed publication. A dashboard or monitor filtering sandbox.state_publication.degraded by disposition sees the new values. Roll back by reverting. No schema or protocol change.

Rollout

Only internal-api changes. While old and new replicas run together, a node's publication over such a row fails on an old replica and commits on a new one, so it can alternate until the rollout completes. Nodes are unaffected.

Stack

Lands on top of #1411 (parse the published status once at ingest). Merge #1411 first; this branch holds only the one commit above it.

AI assistance: Claude Code drafted the code, tests and this description, and ran the validation.

Walkthrough

The publication store now skips activation rollback rows whose stored lifecycle cannot be parsed. Pause-failed recovery skips rows whose stored lifecycle is not Quarantined. Added metrics identify the stored lifecycle field and the recovery-skip disposition. Tests cover successful publication with skipped non-canonical rows and recovery of canonical quarantines.

Possibly related PRs

• perplexityai/SPACE#1420: This PR covers the same publication behavior and changes the same store, tests, and metrics.
• perplexityai/SPACE#1411: This PR changes lifecycle parsing and receipt-selection queries in the same store functions used by this change.

Severity of issue fixed: Medium

Merge Risk: Low · up to 47a23

Publication can proceed past malformed lifecycle rows, which remain unchanged. The change is mergeable with mixed-row activation coverage as a follow-up.

Security architecture risk: Low · up to 47a23

The change prevents one malformed record from blocking unrelated updates. Ownership checks and transactional safeguards remain in place. Skipped records still require repair, and their eventual recovery is not fully established.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• observed — The changed writers remain scoped to sandboxes currently owned by the authenticated publishing node. Activation rollback additionally requires matching active-execution generation and activation-attempt identity; pause-failed recovery requires the expected quarantine provenance. The PR does not remove these scope restrictions.

Trust Boundaries and Controls

• observed — A skipped non-canonical pause-failed row retains its quarantine. Canonical recovery still requires an exact successful ownership-and-quarantine-checked write; a failed write aborts publication. Skipping malformed text therefore does not itself authorize quarantine release.

Resilience and Maintainability Implications

• observed — Malformed activation-rollback rows do not undergo execution retirement, port invalidation, or lifecycle convergence. Their unchanged records are a pre-existing condition—the base also left them unchanged by aborting publication—not an established new exposure. Head permits unrelated work to commit and emits no rollback-completion event for the omitted row.

Full details: Description Follows The Pr Template

Explanation

The PR description contains all required sections and content: ## Summary states the merge behavior; ## Validation lists commands and results; ## Severity and risk gives medium severity and low risk; and AI assistance: identifies Claude Code and the drafted parts.

Full details: Bug Fixes Name A Regression Test

Explanation

The pull request fixes application behavior in crates/. The implementation skips non-canonical lifecycle rows instead of aborting publication. The validation section names healthy_report_recovers_only_a_pause_failed_quarantine, activation_rollback_receipt_converges_its_target_out_of_every_live_lifecycle, and the new node_publish_recovers_pause_failed_rows_past_a_non_canonical_one; it states that the tests fail on the base and pass at this head. The diff confirms the regression tests and the changed behavior.

Full details: Weakened Safeguards Are Justified

Explanation

No weakened safeguard matches the failure criteria. The diff changes two existing tests from expecting publication failure to requiring success and unchanged malformed rows; the PR description gives the specific reason: non-canonical lifecycle rows must no longer abort the whole publication. The same diff adds a focused integration test with assertions for canonical recovery and unchanged padded-row state. No lint, CI, allowlist, baseline, or repository guard is removed or weakened.

Full details: Public-Safe Content

Explanation

No credentials, tokens, private keys, internal URLs, private links, cloud identifiers, workstation paths, production logs or measurements, incident details, or undisclosed security vulnerability appear in the reviewed diff, title, or description. The reported validation data refers to test environments, not production.

Full details: Title check

Explanation

The title starts with a bracketed tag "[cr-test]" and then "internal-api:", which is not the required lowercase area prefix on its own. The summary after the colon is lowercase and describes the main change: skipping one non-canonical stored lifecycle instead of aborting the node's whole publication. The summary matches the changeset, which makes non-canonical lifecycle rows skip instead of failing publication. The extra "[cr-test]" tag is a second prefix that the requirement does not allow, so the title does not follow the required format.

Resolution

Remove the "[cr-test]" tag so the title starts with a single area prefix, for example "internal-api: skip one non-canonical stored lifecycle instead of aborting the node's whole publication" or "[api] skip one non-canonical stored lifecycle instead of aborting the node's whole publication". Keep the summary lowercase and without a trailing period.

Add a mixed-row activation-rollback publication test.

The current activation-rollback tests publish malformed and eligible rows separately. They cannot detect a regression where a bogus lifecycle suppresses other rollback candidates in the same publication. Add one publication containing both rows, then assert that publication succeeds, the bogus row remains unchanged, and the eligible row converges.
