Size process to the risk of each change by palermo-git · Pull Request #22 · baselabs/ash_onetime

palermo-git · 2026-10-28T10:16:06Z

Owner ruling, October 28, 2026: process is sized to the risk of the specific change, never the repository. Rewrites the instruction files to the heavy/light tier rule, moves history to docs/reference/agent-history.md, and narrows .kimosabe/critical-surfaces. Instruction files and docs only.

Summary by CodeRabbit

Dependency Updates
- Minimum supported versions are now Ash 3.37.2, AshPostgres 2.15.2, and AshSql 0.8.4. Ash remains supported below version 4.0.0. Update dependencies below these minimums before upgrading.
- AshPostgres 2.15 requires SQL helper-function version 7; follow its migration requirements when upgrading.
Documentation
- Setup, operations, and upgrade guides now reflect the updated requirements and compatibility information.

Owner ruling, October 28, 2026: process is sized to the risk of the specific change, never the repository. AGENTS.md: "Required checks before reporting a change complete" is replaced by the heavy/light workflow block; heavy covers admission, scope, replay safety, the store, tokens/signers/keys, verification, the effect paths and migration templates. The same command list is now the declared local gate for heavy changes. The platform bullet is condensed. .kimosabe/critical-surfaces drops scripts/check_mutations.exs and test/** (gate tooling and tests, not heavy-tier product paths). Moved byte-for-byte to docs/reference/agent-history.md: the superseded Required checks framing and the original platform bullet.

Walkthrough

The pull request raises the minimum Ash, AshPostgres, and AshSql versions across project requirements, checks, and documentation. It also updates repository workflow instructions and removes mutation tooling and tests from the listed critical-surface paths.

Changes: Security Dependency Floors

Layer / File(s)	Summary
Dependency requirements `mix.exs`, `lib/mix/tasks/ash_onetime.doctor.ex`	The Ash floor is now 3.37.2. The AshPostgres and AshSql minimums are now 2.15.2 and 0.8.4.
Floor validation `.github/workflows/ci.yml`, `scripts/check_mutations.exs`, `scripts/check_optional_matrix.exs`, `scripts/check_package.exs`, `test/mix/*`, `test/mix/tasks/ash_onetime.doctor_test.exs`	CI compatibility values, package metadata checks, compatibility checks, mutation fixtures, and tests use the updated floors.
Dependency-floor documentation `CHANGELOG.md`, `CONTRIBUTING.md`, `README.md`, `docs/ROADMAP.md`, `docs/adr/0004-security-driven-ash-floor.md`, `documentation/`, `documentation/livebooks/`, `usage-rules.md`	The project documentation records the updated requirements, security-floor history, and upgrade guidance.

Repository Workflow Instructions

Layer / File(s)	Summary
Workflow guidance `AGENTS.md`, `docs/reference/agent-history.md`, `.kimosabe/critical-surfaces`	`AGENTS.md` adds risk-based workflow and platform guidance, and links to historical instructions. The critical-surface paths no longer include mutation tooling or tests.

Priority: Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Other

Merge Risk: Moderate · up to 2a7d2

The dependency floors are raised as intended. However, consumers who use the optional Plug integration can still resolve a plug_crypto version with a known secret-disclosure advisory. Add a patched constraint before merging. The workflow and upgrade documentation have smaller inconsistencies that can be cleaned up alongside.

mix hex.audit flagged the lock after advisories published since the last green main: Ash 3.34.6 (EEF-CVE-2026-96581, fixed 3.37.2; EEF-CVE-2026-114214, fixed 3.37.1), AshPostgres 2.14.5 (EEF-CVE-2026-115627 and -115635, fixed 2.15.2; 2.14.5 retired) and Plug.Crypto 2.2.0 (EEF-CVE-2026-105963, fixed 2.2.1). Lock: ash 3.37.2, ash_postgres 2.15.2, ash_sql 0.8.4, plug_crypto 2.2.1; other packages unchanged. Floors: Ash >= 3.37.2 and < 4.0.0, AshPostgres ~> 2.15 and >= 2.15.2, AshSql ~> 0.8 and >= 0.8.4 (AshPostgres 2.15.2's own minimum). The doctor, CI floor cell, core-floors case, package check, dependency-security and pin tests, and mutation rows move together.

- Around line 11-12: Update the critical-surface classification to include the
Heavy modules admission.ex, scope.ex, replay_safety.ex, key_resolver.ex, and
key_source.ex, keeping them grouped with the related store, token, signer, and
verifier entries.

Review comments at @AGENTS.md:
- Around line 31-33: Reconcile the Light workflow in AGENTS.md with
CONTRIBUTING.md by explicitly stating which completion rule applies, or update
CONTRIBUTING.md to use the same risk tiers and focused-check requirements;
ensure the two documents no longer prescribe conflicting checks before a change
is considered complete.

Review comments at @docs/adr/0004-security-driven-ash-floor.md:
- Line 256: Update the dependency constraints so consumers using Plug cannot
resolve an affected Plug.Crypto version, while keeping Plug.Crypto optional; add
a consumer-resolution check that verifies the constraint is enforced.

Review comments at @documentation/upgrading.md:
- Line 24: Update the upgrade guidance alongside the `mix deps.update` command
so consumers are instructed to widen the `ash_onetime` version constraint when
the next minor release is available and include `ash_onetime` among the
dependencies updated by the command.

Align the T2 surface with the Heavy paths.

AGENTS.md marks admission.ex, scope.ex, replay_safety.ex, key_resolver.ex, and key_source.ex as Heavy, but .kimosabe/critical-surfaces does not list these existing files. If the T2 consumer uses this file, changes to them can avoid the required T2 trailer. The checker and tests remain in CI; the issue is the inconsistent classification.

Reconcile the Light workflow with CONTRIBUTING.md.

AGENTS.md permits focused checks followed by a push for Light changes. CONTRIBUTING.md still requires the full battery before reporting any change complete, including mutation, Livebook, package, and optional-matrix checks. State which rule applies, or update CONTRIBUTING.md to use the same risk tiers. (raw.githubusercontent.com)

+the explicit AshSql requirement moves to `~> 0.8 and >= 0.8.4` so the declared minimum is the
+one the `core-floors` case can actually resolve with AshPostgres 2.15.2. The doctor, exact CI
+floor lane, `core-floors` case, package metadata check, dependency-security tests, and mutation

Constrain Plug.Crypto for consumers.

The lockfile update does not constrain consumer resolution. A consumer using Plug can retain Plug.Crypto 2.2.0, which is affected by EEF-CVE-2026-105963. In an affected host application, a malformed request can expose a secret in logs. (github.com)

Add a patched optional Plug.Crypto constraint and a consumer-resolution check. SECURITY.md treats vulnerable dependency ranges as part of this package’s security surface.

Based on learnings: check every affected advisory range before flagging a dependency.

Include the ash_onetime upgrade step.

The guide currently recommends {:ash_onetime, "~> 1.6.0"}, which excludes the next minor release. This command updates only the named dependencies and their children, not ash_onetime. (hexdocs.pm)

When the next release is available, instruct consumers to update their ash_onetime constraint and include ash_onetime in the update command.
