[cr-test] preview candidate CodeRabbit config on #1406, do not merge - #1439
Temporary draft for previewing a candidate .coderabbit.yaml with @coderabbitai review --preview-config. The base branch carries the candidate
configuration, and this branch adds the change from #1406 on top, so the diff is
exactly #1406's change. This pull request will be closed without merging, and
both branches deleted.
Validation
Does not apply.
Severity and risk
Severity: does not apply. Risk: none; it will not be merged.

… whole and delete the renderers
pplx-space-sandbox-portability still rendered SET-list fragments for the
sandboxes row, its executions and its port exposures
(clear/write/publish_clear_or_preserve_current_local_artifact_marker_assignments,
suspended_k8s_finalization_sql and quarantined_k8s_finalization_sql with
SuspendedK8sFinalizationSql and SuspendedTargetNodeAssignment). The
data-store rules keep a statement whole at its query site and allow only a
whole portability boolean predicate to be interpolated.
Each statement that interpolated a renderer now spells it out at its query
site in sandbox-store (drain, ingest, orphan, pod_tracking, repair, suspend)
and in the cluster controller's pod-less drain give-up and started and
failed-restorable repair stores. Statements whose only interpolations are
portability predicates are built once in a LazyLock; the two proof shapes of
pod_tracking's started recovery are two whole statements. The orphan guard
and repair row-state guard fragments, which the reconciler scans also use,
stay as they are. drain::revert_pod_less_resident_to_suspended returns
whether the row flipped instead of the renderer.
The sandbox_writes ratchet drops its two renderer-call patterns, which match
nothing once the renderers are gone, and its comments about renderers; the
statement-head pattern and every baseline cap are unchanged.
Every statement text is unchanged: a Postgres statement log of the touched
crates' tests on the base and on this change records the same statements,
apart from sql! locator line numbers.
Sandbox store and controller finalization and recovery paths now construct SQL directly instead of using portability assignment renderers. The portability helpers and related types are removed. The sandbox write ratchet now matches SQL statement heads that target sandboxes; its allowed paths and required checks are unchanged.
Possibly related PRs
perplexityai/SPACE#1360: Makes the sandbox write ratchet comparisons required; this change updates the same ratchet.
This change moves sandbox finalization and recovery SQL out of shared helper functions and into the code that runs it, and narrows the architecture write check to match. The review found no change to the statements that are executed or to their guards, so behavior should be unchanged. Normal CI and the existing storage tests should be enough before merging.
Security architecture risk: Low · up to 3a4a5
The inspected changes preserve existing identity checks, snapshot guards, and transactional cleanup. No new attack path was demonstrated, but recovery-path integration was not completely verified.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
observed — The inspected writes affect selected sandbox rows and their associated executions, port-exposure observations, and cleanup records. SQL values remain bound parameters; dynamically assembled fragments come from fixed predicates and literal aliases rather than published report text.
Trust Boundaries and Controls
observed — Published-state candidate selection retains active-node ownership and execution-generation fencing. Pod-less drain continues to rely on caller-held node, sandbox, and execution locks, while its update independently retains snapshot eligibility, no-newer-bytes, and ambiguity guards. Those caller obligations already existed at the base revision.
Resilience and Maintainability Implications
observed — Inspected controller repair paths roll back when guarded updates refuse the transition and propagate cleanup failures before commit. Failed-restorable repair retains expired-lease and live-execution checks, clears lease state, removes the tolerated failed observation, and resets exposure observations in one caller-owned transaction.

Full details: Bug Fixes Name A Regression Test
Explanation
PASS: This pull request is a structural SQL-rendering refactor, not an application behavior defect fix. The commit states that statement text remains unchanged, and the diff changes renderer placement and architecture-ratchet documentation. The Validation section therefore does not need to name a regression test.
Full details: Public-Safe Content
Explanation
No prohibited public-safety content appears in the reviewed diff, title, or description. The diff contains source code, SQL statements, and generic node or cluster terminology. It contains no credentials, tokens, private keys, URLs, hostnames, cloud ARNs or account IDs, personal absolute paths, production logs, measurements, incident details, or undisclosed vulnerability description.
Full details: Description Follows The Pr Template
Explanation
The description fails two required items. The Summary describes the preview setup and says the PR will not merge, but it does not state what merging the code change does. The Validation section only says “Does not apply”; it does not name a run and result or say “CI on this head”. Severity and risk are present, and the AI assistance line identifies Claude Code and the drafted parts.
Resolution
Rewrite Summary to state the behavior introduced when the change merges. Replace “Does not apply” under Validation with the command or checks run and their result, or with exactly “CI on this head”.
Full details: Weakened Safeguards Are Justified
Explanation
The diff weakens a repository guard without an allowed justification. ARCHITECTURE.toml removes the two sandbox_writes patterns at base lines 214-216 that detected sandbox-portability assignment renderer calls. The head keeps only the statement-head pattern. The PR description gives no specific reason for removing these patterns, and the adjacent comments do not justify the removal.
Resolution
Restore the two renderer-call patterns, or add a specific rationale in the PR description or adjacent ARCHITECTURE.toml comment that explains why removing this guard is safe and what prevents equivalent renderer calls from bypassing sandbox_writes.
Full details: Title check
Explanation
The title uses the required bracketed area format and starts its summary with a lowercase word, but it describes a CodeRabbit preview and merge status instead of the SQL and sandbox-finalization changes in the changeset.
Resolution
Replace the title with a bracketed or lowercase area that identifies the sandbox storage change, followed by a lowercase summary of replacing portability SQL renderers with direct statement SQL.
