Third core feature pulled into a plugin (blueprint-only, like slides). The
employee directory is a read-only lookup over a separate HR database.
- plugins/employees/: manifest (api_prefix /api/employees, no deps), api/ (moved
blueprint, contract-pure: success/error/ErrorCodes + employee_connection all
from shopdb.api), plugin.py (get_blueprint, get_models -> []).
- employee_connection STAYS core infrastructure in shopdb.api (config-driven
external DB connector, shared by search + the notifications shopfloor feed). So
no get_services needed and no contract change - the plugin owns the directory
FEATURE, core owns the shared connector.
- Fixed a latent bug in the move: error paths used ErrorCodes.DATABASE_ERROR
which does not exist -> ErrorCodes.INTERNAL_ERROR (so a directory outage now
returns a clean 500 envelope instead of an AttributeError crash).
- De-cored: deleted shopdb/core/api/employees.py, removed from
CORE_BLUEPRINT_NAMES + core/api/__init__ import/__all__. Registered in
instance/plugins.json.
Pinned first: validation (400) + graceful-degrade (500) characterization tests;
the degrade test caught the DATABASE_ERROR bug and goes green with the fix.
184 tests pass, naming green, app boots 9 bundled plugins, endpoint verified live.
Plugin extractions complete: knowledgebase, slides, employees.
