Odoo's res.config.settings framework only supports auto-persisting fields of type boolean/integer/float/char/selection/many2one/datetime via config_parameter=. theme_logo (Binary) doesn't qualify, and because it was injected into the *shared* res.config.settings form, it broke every Settings tab across the whole install (including unrelated ones like Website/eLearning) - any settings load triggered default_get, which scans all fields on the model and raised. Caught via live testing in the browser, not by the automated suite, since the failure only surfaces on create()/default_get() of a resx.config.settings record, which the existing tests didn't exercise for other apps' tabs. Fixed by removing config_parameter from the field and persisting it manually through get_values()/set_values() overrides, base64-encoded into the same ir.config_parameter key the QWeb template already reads from - so the storage format is unchanged, just how it gets there. Audited every other config_parameter= field across all modules (grep) to confirm none of the others have the same problem - all are Char/Integer/ Boolean, which are on the whitelist. Verified against the live container: settings load and save cleanly for every module's tab, the logo round-trips through upload -> config parameter -> template read, and a full test run across all 9 modules (56 tests) plus a sweep of every custom button (call_button, matching the exact browser click path) and every public/portal page passes clean.

Community OS
A brand-neutral, resellable suite of Odoo 19 Community modules for community and cultural organizations. First deployment: the Tamil Nadu Cultural Society of Canada (TNCSC).
Vendor: Metatroncube Software Solutions LLP · Waterloo, Ontario Target platform: Odoo 19 Community Edition (LGPL-3) · PostgreSQL 16 · Python 3.12
community_*is a placeholder module prefix. Replace it with a unique vendor prefix before publishing to the Odoo App Store so technical names never collide with anything already listed.

Product-layer modules never mention a client name, never hardcode a price,
a colour, an account code, or an email address. Anything client-specific
is a configuration record, seeded only by a *_deployment module. Landing
a new client means writing a new clientname_deployment module — the
product code never changes.

Local development
cd deploy
docker compose up
Odoo will be available at http://localhost:8069. The ../addons folder is
mounted read-write, so changes to module code are picked up on restart (dev
mode reload is enabled in deploy/odoo.conf).
Licensing & resellability guardrails
- Every product module is licensed
LGPL-3. - No
community_*module may depend on an Odoo Enterprise module — seeAppendix Ain the project plan for the Community-only allowlist. - No client identity (name, email, colour, price, account code) may appear
in a product module. This is enforced in CI by
scripts/check_brand_leak.py. - All client-variable behaviour is configuration data, seeded by the deployment layer, never a literal in product code.
- Every product module ships an App-Store-ready manifest, a
tests/package, and astatic/description/index.htmllisting page.
See CommunityOS_Implementation_Plan_for_Claude_Code.md for the full,
phase-by-phase build plan.
CI
.github/workflows/ci.yml installs every module against Odoo 19 +
Postgres 16 with --test-enable, runs the brand-leak grep, and lints with
flake8 / pylint-odoo.
