Completes the marketplace security model. Verification stops being advisory:
a plugin only loads or migrates when its tree matches a trusted signature, and
plugins are pulled from a signed shelf with anti-rollback and revocation.
Enforcement (default OFF - existing deploys unchanged):
- verification.py PluginVerifier, shared by the loader (verify-at-load, before
plugin.py is imported) and the migration manager (verify-at-migrate, before
any DDL). Fail-closed: an unsigned/tampered/wrong-key plugin does not run.
- Gated by PLUGIN_REQUIRE_SIGNED. PLUGIN_DEV_TRUST_DIRS exempts named dirs but
only under DEBUG/TESTING; production ignores it.
- flask plugin stamp-bundled writes provenance into in-tree plugins so
verify-at-load applies to bundled plugins too (image build step).
- tier:core manifest guard: uninstall/disable refuse a core-tier plugin.
Shelf (shelf.py):
- Signed shelf-index.json (+ .sig): monotonic serial (a site refuses an older
index - anti-rollback), revoked list carried across builds, per-entry
version/tier/core_version for browse. Index is a browse layer only; adopt
reads security-bearing fields from the verified artifact.
- flask plugin shelf-build / shelf-list / adopt / audit. adopt verifies index +
artifact (signature + every file hash), unpacks to staging, re-verifies, then
atomically moves into place and installs+enables the closure. Refuses a
downgrade without --force-downgrade. Anti-rollback serial stored in
instance/shelf-state.json.
- config PLUGIN_SHELF_DIR; the app only reads the folder, never speaks a
network. .env.example + docs/PLUGIN-SIGNING.md document the flow.
22 tests: verifier policy (off / no-keys / signed / tampered / wrong-key /
dev-exempt), verify-at-load + verify-at-migrate integration, tier guard, index
sign/verify + tamper/wrong-key, serial state, revocation, version resolution,
verified atomic unpack + tamper refusal. Live-smoked keygen->pack->shelf-build
->list->adopt->audit + serial guard. 1050 pass, naming green.
Additive, zero-risk-to-running-sites prep for the plugin catalog. No
distribution or lean-build behavior yet; fixes latent bugs and adds the
declarative + validate tooling later phases build on.
Fixes:
- upgrade_all_plugins iterates registry.get_all(); only adopted plugins are
migrated. Removes the phantom hasattr(registry, 'list_installed') probe
that always fell through to migrating every folder on disk (unadopted DDL
ran with full DB rights on every deploy).
- Reverse-dependency checks on uninstall/disable read dependencies from the
manifest on disk via _installed_dependents, so an installed-but-unloaded or
disabled dependent is counted. Uninstall blocks on any installed dependent;
disable blocks on an enabled dependent.
- _sort_by_dependencies detects a dependency cycle (back edge in the DFS) and
raises PluginDependencyError instead of looping or dropping a plugin.
New:
- flask plugin validate <name>: manifest loads + name match, manifest-schema
check, core_version admits the framework contract, declared dependencies
exist on disk. No new dependency (lightweight checker); schema ships in the
package at shopdb/plugins/manifest_schema.json (docs/ is stripped on
publish). The check caught that provides is an object, not an array.
- flask plugin apply-profile <file>: declarative install AND enable of a
chosen plugin set plus its hard-dependency closure, in dependency order,
idempotent. Replaces the hand-ordered runbook sequences that could enable a
plugin that was never installed. deploy/site-profile.example.json template.
- Dockerfile header corrected (all 13 catalog plugins, not "eleven core").
10 new lifecycle tests (reverse-deps from disk, cycle detection, upgrade-all
scope, profile closure, schema, all 13 manifests match schema). 1018 pass,
naming green.
Fills the review's highest-value coverage gaps in the framework's own core
feature.
New tests/test_plugin_lifecycle.py: manager enable/disable dependency guards
(beta depends on alpha - enable-beta-first refused, disable-alpha-while-beta-on
refused) via synthetic plugins; enable seeds a plugin's RBAC permissions
idempotently; registry disable-survives-reload, corrupt-file recovery, and the
equipment->machines rename migration; `flask seed settings` idempotency.
test_plugin_contract.py: BUNDLED_PLUGINS now covers all bundled plugins incl.
geenforce, measuringtools, warranty (was 9, contradicting the CLAUDE.md "all
bundled satisfy the contract" claim); the structural checks now run against them.
test_authz.py: account lockout auto-unlock path (expired lockeduntil -> correct
password logs in and clears the lock state), previously untested.
All new tests pass; naming green.
