archcheck: delete file_size and the checks the layers rule covers by ac-pplx · Pull Request #1222 · perplexityai/SPACE

ac-pplx · 2026-10-31T04:59:56Z

Summary

Every archcheck rule is to be required from the day it lands, with exceptions
that only shrink: no new baseline entries, no raised caps, and stale entries
removed. A rule that can't be enforced that way is deleted. The README now
states this policy under "Configuration and modes". This deletes the advisory
file_size rule, which fails that test.

[file_size] was seeded with 99 entries on 2026-10-13, reached 102, and lists
97 production files over 1,000 code lines today; #1156 and #1159 lowered caps.
What can't be made required is listed_no_growth: in the 14 days to
2026-10-31, 149 of main's 371 first-parent commits (40%) added more lines than
they deleted to one of the 97 listed files (git log --numstat, raw lines).
Requiring it would block about that share of pull requests. After this lands,
nothing flags a new file over 1,000 lines; since 2026-10-13 that happened in 23
of about 580 commits on main.

pattern_ratchet.direct_tables, also advisory, stays: open pull requests
shrink it (#1202).

Two sbx-mgr SQLite checks go too, since the required layers rule now covers
them: layers.storage_access lets only stores, storage helpers and baselined
edges depend on a database driver or a storage helper, and
layers.store_edges lets only a store's listed users depend on it.

dependency_fence, the whole rule, with its sbxmgr_rusqlite and
sbxmgr_sqlx instances. Every package they fenced (rusqlite,
libsqlite3-sys, pplx-space-sqlite, sqlx, sqlx-core, sqlx-sqlite)
is a [rules.layers.storage] driver or helper, which storage_access keeps
out of the normal and build dependencies of every sbx-mgr crate but its two
stores.
pattern_ratchet.sbxmgr_sqlite: twelve regexes for SQLite calls and SQL
literals in sbx-mgr's crates, which aliases escaped; storage_access
confines SQLite to the stores at the crate level instead.

pattern_ratchet.sbxmgr_sqlite_schema stays, because layers does not see
what it catches: the storage checks read only dependency edges, skip stores
and helpers and tolerate baselined edges, so db-migrate, a store that already
has sqlx and rusqlite, could name sbx-mgr's migrator again, and a node service
with a baselined driver edge could open sbx-mgr's database by path.

What this narrows:

pplx-space-sbxmgr-migrations, an l30_storage crate, may now take
rusqlite, libsqlite3-sys and pplx-space-sqlite, which
sbxmgr_rusqlite allowed only the store. CI's
run_sbxmgr_production_checks still rejects a normal dependency on
rusqlite or pplx-space-sqlite there, but not a build or dev dependency,
nor libsqlite3-sys.
The migrations crate's sources are no longer scanned for SQL text;
state.writes still reports a write statement there that names another
store's table.
Dev-dependencies, which the fences covered and storage_access leaves to
tests.
pplx-space-sbx-mgr's baselined storage_access edge to the
pplx-space-common-jobs helper, which it uses for job types today.

Merging removes the file_size module, its configuration and its
[rules.file_size] tables, its [file_size] baseline table and base-copy read
(including --write-baseline=file_size), and the now-unused
ProductionFile::code_lines. The baseline was edited by hand, so the other
tables keep their comments, and its header matches what --write-baseline
generates. The shared count ratchet and the code-line definition stay, since
pattern_ratchet uses them; scripts/move_crates.py drops its check of
dependency-fence coverage, and that check's test. Two small changes follow
from [file_size] no longer always being present:

Baseline::write puts one blank line between whichever parts it writes.
When the base baseline is not TOML and no rule compares tables with it,
skipped() uses each rule's own lines. Without this, deleting file_size
would leave that warning ending in ; skipped.

Tests that used file_size for behaviour the pattern ratchets share now use a
pattern_ratchet fixture; tests of file_size alone are deleted. New
assertions pin Baseline::write's layout and the single warning for a base
copy that is not TOML. The layers tests change only their fixtures and the
expectations that follow from them: their [file_size] lines are gone from
configurations and baselines, so expected baseline line numbers move up by
one. The CI ordering script's comment and test fixtures no longer use
file_size, and five api test modules' doc comments no longer cite a
file-size guidance.

Validation

At this head:

layers_storage_checks gains a case for a driver declared in a table of its
own ([dependencies.sqlx]): its finding points at that header line, and the
test fails when that path is broken. The deleted fence test was the only
test of it.
On a scratch commit, cargo arch fails with a required layers finding for
each of: rusqlite added to pplx-space-sbx-mgr
(layers.storage_access.no_crossing), pplx-space-sbxmgr-migrations added
to pplx-space-sbx-mgr (layers.store_edges), and pplx-space-sqlite
added to pplx-space-sbx-mgr-client (layers.storage_access.no_crossing).
cargo fmt --check,
cargo clippy -p pplx-space-archcheck --all-targets --all-features -- -D warnings
and cargo clippy -p pplx-space-api --all-targets --all-features -- -D warnings:
clean.
cargo test -p pplx-space-archcheck: all pass.
cargo arch: exit 0, no findings.
The README's "check a branch as CI does" recipe against this commit's
parent on main, with its ARCHITECTURE.toml as --base-architecture: exit
0, no findings. The line after the summary says the base baseline's
[pattern_ratchet.sbxmgr_sqlite] table is no longer configured, so it is
skipped.
bash ci/scripts/test-order-archcheck-findings.sh and
bash scripts/check-rust-error-policy.sh: pass.
--write-baseline generates the committed baseline header.
The new layout and warning assertions fail when the old writer or a
one-line-per-rule warning is restored.

Severity and risk

Severity: does not apply. file_size was advisory, so no pull request fails
or passes differently without it; the three sbx-mgr checks were required, and
the required layers checks above fail the same changes, apart from the
narrowings listed in the summary.

Risk: a pull request can now add lines to a large file, or add a new file over
1,000 lines, without an advisory annotation, and the narrowings listed in the
summary are no longer checked. Open pull requests
that edit [file_size] entries conflict once this lands; resolve them by
dropping those edits. Roll back by reverting this commit.

Stack

Bottom of a native stack: #1360 goes on top. The layers stack this was first
built on (#1152 → #1161 → #1162 → #1164) has merged.

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

Thanks for opening this pull request! A SPACE maintainer will take a look.

The mechanics of the deletion look right. The concern is the rationale, and the fact that nothing replaces the rule.

[medium] The stated reason for deletion doesn't match how the rule is used
The description says "nothing shrinks the list" and keeps direct_tables because open PRs shrink it. [file_size] shrinks too:
- It went from 102 entries to 98 since 2026-10-13, with no new entries.
- Caps were lowered by #1156 and #1159, and are being lowered by open #1227, #1228 and #1022.
The principle "required from day one, or deleted" isn't written down in the README or ARCHITECTURE.toml. On main, 8 of 10 no_new_entries behaviours are advisory, so it isn't applied elsewhere either. With this PR, nothing signals a new production file over 1,000 lines.
Suggestion: keep file_size with only no_crossing and no_new_entries (new oversized files), which would block far fewer PRs than listed_no_growth. Otherwise, document the required-or-delete policy in the README and say how the other advisory behaviours will be brought in line.
[low] A design decision loses its stated premise
crates/tools/archcheck/README.md, "Module names aren't checked": the PR drops "file_size already bounds how much one can hold" from the reasons. The decision itself is left in place. Is the remaining reasoning still sufficient, or should that paragraph be revisited?
[nit] Stacking
The only dependency on #1164 is baseline fixtures. Rebasing this onto main would let it land or be declined on its own merits, independent of the larger stack.

Withdrawing this approval for now. Any feedback above still stands.

@zibi-pplx thanks for the review; replies below.

[medium] The stated reason doesn't match how the rule is used

You're right, and the description's "nothing shrinks the list" was wrong: [file_size] was seeded
with 99 entries on 2026-10-13, reached 102 and is at 98 now, and #1156 and #1159 lowered caps. What
can't be made required is listed_no_growth: about 40% of main's commits add lines to a listed
file. I've kept the deletion and written the policy down: the README now says that a behaviour is
required from the day it lands, that baselines only shrink, and that a rule that can't meet that is
removed. Making the remaining advisory no_new_entries and no_raised_caps behaviours required is
tracked internally. With this pull request nothing flags a new file over 1,000 lines; since
2026-10-13 that happened in 23 of about 580 commits on main. The description is corrected.

[low] "Module names aren't checked" loses a premise

The other three reasons stand on their own: catch-all modules haven't been appearing, a module's
reach ends at its crate, and a check on module names is easy to evade without changing what the
module holds. I've left the decision as it is.

[nit] Stacking

Done: this is now rebased onto main and out of the stack, so it can land or be declined on its own.
The stack has since landed, so this pull request also drops the [file_size] lines in the
layers tests' fixtures.

#1222 states the policy: a behaviour is required from the day it lands and a baseline only shrinks. This makes the behaviours that were still advisory required: - all five behaviours of pattern_ratchet.direct_tables; - no_new_entries and no_raised_caps of kubernetes_access, capability_identity, substrate_literals and sandbox_writes; - no_new_entries of rootfs_copy and node_manager_commands; - crate_names.stale_entries. A pull request that adds a baseline entry or raises a cap in any of these tables now fails instead of being annotated, and so does a stale crate_names entry. The tree has no findings for them, so the baseline is unchanged. The pull request that adds a pattern_ratchet instance seeds its table, as for the layers checks: while the base branch has no such instance, each entry is an advisory no_new_entries finding, and a base that configures the instance without a table tolerates nothing. Three behaviours stay advisory because they are notices, not checks: crate_names.policy_changed and layers.policy_changed report a policy edit for review, and layers.state.pending is how a new table lands, declared before its migration. The README, the rootfs-backing design note and the comments in ARCHITECTURE.toml no longer describe a new entry as a reviewed exception that is only reported.

Every package they fenced (rusqlite, libsqlite3-sys, pplx-space-sqlite, sqlx, sqlx-core, sqlx-sqlite) is a [rules.layers.storage] driver or helper, which storage_access keeps out of the normal and build dependencies of every sbx-mgr crate but its two stores. - pattern_ratchet.sbxmgr_sqlite: twelve regexes for SQLite calls and SQL literals in sbx-mgr's crates, which aliases escaped; storage_access confines SQLite to the stores at the crate level instead. pattern_ratchet.sbxmgr_sqlite_schema stays, because layers does not see what it catches: the storage checks read only dependency edges, skip stores and helpers and tolerate baselined edges, and state.writes scans only stores' and helpers' write statements, so db-migrate, a store with sqlx and rusqlite, could name sbx-mgr's migrator again, and a node service with a baselined driver edge could open SANDBOX_MANAGER_DB. Its comment now says so instead of contrasting it with sbxmgr_sqlite. What this narrows: - pplx-space-sbxmgr-migrations, an l30_storage crate, may now take rusqlite, libsqlite3-sys and pplx-space-sqlite, which sbxmgr_rusqlite allowed only the store. CI's run_sbxmgr_production_checks, which asserts which crates bring rusqlite and pplx-space-sqlite into the server's normal graph, still rejects a normal dependency on either there, but not a build or dev dependency, nor libsqlite3-sys. - The migrations crate's sources are no longer scanned for SQL text; state.writes still reports a write statement there that names another store's table. - Dev-dependencies, which the fences covered and storage_access leaves to tests. - pplx-space-sbx-mgr's baselined storage_access edge to the pplx-space-common-jobs helper, which it uses for job types today and which sbxmgr_sqlite watched for calls into common-jobs' SQL functions. sbxmgr_sqlite's baseline table was empty. The rule's module, configuration and context code, its cli test, sbxmgr_sqlite's repository tests and their helper, and the rule's README section are deleted. The fence test's dev-dependency case was the only test of a finding on a dependency declared in a table of its own ([dependencies.sqlx]), which places every layers finding on such a dependency; layers_storage_checks gains that case. Comments in ARCHITECTURE.toml, run-rust-checks.sh, the sbx-mgr store's AGENTS.md and pplx-space-sqlite's crate docs now name storage_access where they named the fences. scripts/move_crates.py drops its check of dependency_fence member globs, and that check's test. The change removes the file_size module, its configuration code and its [rules.file_size] tables in ARCHITECTURE.toml, its [file_size] baseline table and base-copy read, its part of the generated header, and --write-baseline=file_size. ProductionFile's code_lines field and count_code_lines go too, since only file_size read them. The baseline was edited by hand, so the other tables keep their comments, and its header matches what --write-baseline now generates. Kept: the shared count ratchet (rules/ratchet.rs), which pattern_ratchet uses, and the code-line definition (context::code_lines). Two small changes follow from [file_size] no longer always being present: - Baseline::write puts one blank line between whichever parts it writes. Without this, a baseline with no table of caps gets a doubled blank line. - When the base baseline is not TOML and no rule compares tables with it, skipped() falls back to each rule's own lines. Without this, the warning ends in "; skipped". crate_names then reports the unreadable copy itself. Tests that used file_size for behaviour the pattern ratchets share now use a pattern_ratchet fixture. These cover renames (merged into pattern_ratchet_renames), --renames from git, the human report, rdjson (document, exact paths, stdout/stderr), base-baseline problems, the skip-line and no-base checks, implicit members, scoped and unscoped --write-baseline, and write errors. The rows of lenient_base_baseline and behaviours not covered elsewhere moved into the pattern_ratchet tables. Tests that only exercised file_size are deleted: its behaviours table, its modes test, its limit digit grouping, write_baseline_output's limit cases, and configuration rows for its keys. New assertions pin Baseline::write's layout, with and without a table of caps, and the one warning that names every pattern_ratchet instance's comparisons for a base copy that is not TOML. Apart from the layers_storage_checks case above, the layers tests change only their fixtures and the expectations that follow from them: their [file_size] lines are gone from configurations and baselines, so expected baseline line numbers move up by one, the warning for a base copy that is not TOML no longer names file_size's comparisons, and a scoped write keeps a stale [crate_names] entry where it kept a stale [file_size] one. The CI ordering script's comment no longer says the report lists file_size findings first. Its test fixtures use a pattern_ratchet code and table, with each case's meaning unchanged. Five api test modules' doc comments no longer cite the file-size guidance.

Walkthrough

The PR removes archcheck’s file_size and dependency_fence rules, moves sbx-mgr SQLite dependency boundaries to layers.storage_access, and updates baseline handling, tests, documentation, and crate-move checks. Skip reporting also changes when an unusable base baseline has no configured comparisons.

Changes: Archcheck policy and baseline updates

Layer / File(s)	Summary
Move SQLite dependency boundaries to `layers.storage_access` `ARCHITECTURE.toml`, `crates/tools/archcheck/src/config.rs`, `crates/tools/archcheck/src/context.rs`, `crates/tools/archcheck/src/rules.rs`, `crates/tools/archcheck/src/rules/dependency_fence.rs`, `crates/libs/sbx/mgr/store/AGENTS.md`, `crates/libs/sqlite/src/lib.rs`, `ci/scripts/run-rust-checks.sh`, `scripts/move_crates.py`, `scripts/tests/test_move_crates.py`, `crates/tools/archcheck/tests/repository.rs`	The sbx-mgr SQLite dependency boundary now uses `layers.storage_access`. The dependency-fence configuration, validation, rule, and crate-move member-directory checks are removed.
Remove `file_size` and update baseline handling `ARCHITECTURE.toml`, `architecture-baseline.toml`, `crates/tools/archcheck/src/baseline.rs`, `crates/tools/archcheck/src/config.rs`, `crates/tools/archcheck/src/context.rs`, `crates/tools/archcheck/src/lib.rs`, `crates/tools/archcheck/src/main.rs`, `crates/tools/archcheck/src/rules/`, `crates/tools/archcheck/tests/repository.rs`, `crates/libs/api/src/controllers/substrate/kubernetes/store/k8s_store_postgres_tests/`	The `file_size` rule and its baseline data and code-line counting support are removed. Baseline output joins nonempty sections, and `skipped` uses rule-specific messages when no base comparisons are configured.
Update pattern-ratchet validation and guidance `ci/scripts/order-archcheck-findings.sh`, `ci/scripts/test-order-archcheck-findings.sh`, `crates/tools/archcheck/README.md`, `crates/tools/archcheck/src/baseline/tests.rs`, `crates/tools/archcheck/src/rules/ratchet.rs`, `crates/tools/archcheck/src/rules/ratchet/tests.rs`	CI ordering scenarios and ratchet tests use `pattern_ratchet` findings and baselines. The documentation describes instance-specific base comparisons, rename handling, stale entries, and baseline policies.

Estimated code review effort: 4 (Complex) | ~45 minutes

Change: Other

Suggested reviewers: the-gigi-pplx

Security architecture risk: Low · up to e23b6

Most production dependency controls remain, and no new runtime database access was demonstrated. However, the replacement is not fully equivalent: it permits some SQLite capabilities outside the designated store that the deleted checks rejected. This weakens a preventive ownership control rather than demonstrating an exploitable runtime vulnerability.

Retained concerns

Low · security · inferred: The replacement weakens the documented store-only SQLite access gate. The deleted fence rejected libsqlite3-sys dependencies from migrations, whereas layers now permits them because migrations is a storage-layer crate. The retained schema ratchet allows that crate, and CI checks normal rusqlite and pplx-space-sqlite dependents rather than libsqlite3-sys. Removing the generic SQLite call ratchet also leaves opens and reads outside its former coverage. Future code can therefore acquire additional direct SQLite capability without changing the ownership policy. This is a preventive-control regression; the PR does not itself add such access, and retained table-write checks still constrain recognized writes.

Security review details

Security Blast Radius

inferred — The demonstrated exposure is a weaker repository policy gate for future source and dependency changes, particularly in migrations. It is not a demonstrated new network, tenant, credential, or deployed database access path. The migrations implementation and manifest are unchanged across the PR comparison and still only embed migrators.

Security Findings and Attack Paths

inferred — A future source change could add libsqlite3-sys to migrations and introduce direct SQLite access without triggering the removed dependency fence. The replacement storage check permits that layer, the schema ratchet allows migrations, and the retained CI dependency assertion does not inspect this package. This supports the ownership-control concern, not a verified runtime exploit.

Trust Boundaries and Controls

observed — The documented database owner remains the sbx-mgr store. CI continues to reject unexpected normal rusqlite and shared SQLite-helper dependents and activation of the store's test-support feature in checked production feature sets. Migrations already had a permitted sqlx dependency before this PR, so the change broadens existing potential capability rather than granting the crate its first database-related dependency.

Resilience and Maintainability Implications

inferred — Consolidating dependency enforcement reduces duplicate policy definitions, but the broader storage-layer exemption no longer mechanically expresses the narrower store-only database-access contract. That mismatch creates control-drift risk even though ordinary non-storage production dependencies remain checked.

perplexityai#1222 states the policy: a behaviour is required from the day it lands and a baseline only shrinks. This makes the behaviours that were still advisory required: - all five behaviours of pattern_ratchet.direct_tables; - no_new_entries and no_raised_caps of kubernetes_access, capability_identity, substrate_literals and sandbox_writes; - no_new_entries of rootfs_copy and node_manager_commands; - crate_names.stale_entries. A pull request that adds a baseline entry or raises a cap in any of these tables now fails instead of being annotated, and so does a stale crate_names entry. The tree has no findings for them, so the baseline is unchanged. Merge groups now run the same comparison against the group's base_sha, through ci/scripts/run-archcheck.sh, which pull requests share, and a required finding fails the group. The pull request that adds a pattern_ratchet instance seeds its table, as for the layers checks: while the base branch has no such instance, each entry is an advisory no_new_entries finding, and a base that configures the instance without a table tolerates nothing. Three behaviours stay advisory because they are notices, not checks: crate_names.policy_changed and layers.policy_changed report a policy edit for review, and layers.state.pending is how a new table lands, declared before its migration. The README, archcheck's not-added advice, the rootfs-backing design note, the substrate AGENTS.md, split_rust_module.py and the comments in ARCHITECTURE.toml no longer describe a new entry as a reviewed exception that is only reported.

Two shared costs set the time of many listed slow tests. - pplx-space-api hashed every test password at bcrypt cost 12, 0.3-0.5 s per hash on a loaded CI runner. The external-console fixture, session and identity tests, and native-build ownership cases each pay two to four. hash_password now uses cost 4 when the crate's own tests build it, and 12 otherwise. verify_password reads the cost from the stored hash, so the same paths run. In CI the 48 affected tests went from 75.8 s to 35.4 s in total. - sha2 ran at opt-level 0 over mebibytes of rootfs images. Optimized, the template-mgr tests went from 27.1 s to 8.3 s in total. A CI trial that optimized every dependency added 3.5 minutes to the uncached build and nothing to the run as a whole, so only sha2 joins the existing per-package overrides. The 57 exceptions of affected tests that now run under 0.8 s are removed, as are two whose tests #1222 deleted. 220 remain.

ci/test-duration-budget.toml listed 449 tests allowed over the 2 s limit. This makes most of them fast without changing what they prove, and removes their exceptions. Production keeps today's values: every new field, parameter or test constructor defaults to the constant it replaces. Budget: - 170 exceptions were for tests that never reached 1.8 s in 28 CI runs; a test is now listed from 1.8 s. - Two named tests that #1222 deleted. Shared costs: - pplx-space-api hashed test passwords at bcrypt cost 12, 0.3-0.5 s per hash in CI; its own tests now use cost 4. - sha2 runs optimized in tests: the template-mgr rootfs tests went from 27 s to 8 s in total. Optimizing every dependency instead added 3.5 minutes to an uncached build and nothing to the run. Waits, sweeps and sizes, by cause: - Tests that waited out a production timeout or backoff get an injectable bound: the api Kubernetes test substrate's reflector, delete and restore-poll waits; list page byte budget, quota lock, builder and node-manager retries; grpc handshake allowances; gateway peek budget; node-mgr usability budget; dispatcher held-back backoff; node-group mirror bounds; drain lock timeout; job retry backoff; volmgr page-cache advice window; snapshot-retention raw page size. - Fixed sleeps that stood in for 'blocked on a lock' now poll for the waiter; fixed observation windows end on the condition they wait for. - Sequential sweeps over states, shapes, cases or shards become rstest cases (the sbx-mgr-store state-write matrix alone becomes 270). - Fixtures shrink where the size was incidental: KiB list pages, a 9 MiB push source, 1 MiB rootfs images, 9 idle rounds. Tests whose cost is inherent keep their exceptions: planner tests that need production-scale tables, SDK-fixed stall windows, and per-test Postgres containers.
