Summary

Adds pplx-space-template-mgr-store (crates/l30_storage/template/mgr/store), a storage-layer crate whose [package.metadata.space.state] declares sqlite.template-manager = ["node_dirty_ref_revision"]. archcheck requires every live table to have an owning store, and a new table can't be added to [layers.unowned]. So the migration that creates this counter (#1235) needs the declaration to merge first.

The crate owns only that table; template-manager's other tables stay baselined. It has no functions or SQL yet. Its first statements arrive with their first caller in #1235, which also adds template-manager's dependency and the [rules.layers.store_users] entry.

Validation

At this head:

• ci/scripts/run-archcheck.sh origin/main "": 0 required. 1 advisory layers.state.pending for the declared table, expected until template-manager: ack node dirty refs by revision so a re-enqueue during a send survives #1235's migration lands.
• cargo fmt --check, and workspace cargo check and cargo clippy -D warnings with all targets and features: clean.
• SPACE_CI_REQUIRE_TEST_DEPS=1 cargo nextest run --all-features for this crate, pplx-space-template-mgr and pplx-space-sqlite: 324/326 pass. The two failures are template-mgr's NoCoW tests, which need CI's btrfs fixture (ci/scripts/with-nocow-test-filesystem.sh); the validation host has no btrfs. They were not validated here.

Severity and risk

Severity: does not apply; no runtime change.
Risk: none at runtime, since nothing depends on the crate yet. Roll back by reverting, as long as #1235 has not merged on top.

Walkthrough

The workspace now includes the pplx-space-template-mgr-store crate and exposes it as a workspace dependency. The new crate manifest inherits package settings and declares SQLite template-manager state metadata. Its crate-level documentation describes its stated ownership of node_dirty_ref_revision and forbids unsafe code.

• perplexityai/SPACE#1235: Adds the migration and store API that this change prepares for.
• perplexityai/SPACE#1277: Adds the node_dirty_ref_revisions migration to rollback history and declares the owning store needed before bundling that migration.

Merge Risk: Minimal · up to 156fd

No runtime behavior or database implementation changes are introduced by this PR.

Security architecture risk: Minimal · up to 156fd

The new crate declares storage ownership but adds no executable database operations, active callers, or permission changes. Existing database behavior remains unchanged.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The introduced effect is limited to workspace availability and static ownership validation for one named SQLite table. The changed files expose no new executable entrypoint, database operation, credential use, or tenant or identity transition.

Trust Boundaries and Controls

• observed — The ownership declaration is architectural metadata, not a runtime database permission grant. It is consumed by static validation, while the new crate contains no code that accesses the database or changes an authorization control.

Explanation

The description contains all required sections and content. ## Summary states that the change adds the storage crate and table ownership. ## Validation names the checks and reports their results. ## Severity and risk states that severity does not apply and gives a runtime risk. AI assistance: identifies Claude Code and the parts it drafted.

Full details: Bug Fixes Name A Regression Test

Explanation

PASS: The pull request does not fix an application behavior defect. The diff only registers a new workspace crate, adds state metadata for node_dirty_ref_revision, and adds an empty library with documentation. No runtime behavior under crates/, shim/, or ui/ changes, so the regression-test requirement does not apply.

Full details: Weakened Safeguards Are Justified

Explanation

The pull-request diff adds a workspace member, a dependency entry, a lockfile package record, and a new crate with inherited workspace lints. It removes or weakens no test, assertion, lint, CI check, allowlist, baseline, or repository guard.

Full details: Public-Safe Content

Explanation

No public-safety violation found. The reviewed diff contains only workspace/package metadata and crate documentation; a scan found no credentials, tokens, private keys, URLs, ARNs, personal absolute paths, logs, or measurements. The title and description contain public issue references, repository-relative CI paths, and ordinary project terminology only.

Full details: Title check

Explanation

The title uses the prefix "[cr-test] template-mgr-store:", which is not the required lowercase area prefix, and it includes the "[cr-test]" tag. The summary after the colon starts with a lowercase word ("add") and names the change accurately: a store that owns node_dirty_ref_revision. The area prefix matches the crate path, but the extra bracketed tag breaks the required format.

Resolution

Remove the "[cr-test]" tag so the title starts with the area and a colon, or the area in square brackets. For example: "template-mgr-store: add a store that owns template-manager's node_dirty_ref_revision". Keep the summary lowercase and drop any trailing period.
