Discourse v2026.10.0 removed LlmModel#toggle_companion_user; bot users now
belong to AI agents (discourse/discourse 5e11656cae, "Gate AI bot user
provisioning on feature settings"). The AI gateway registration still
called it and failed with "undefined method 'toggle_companion_user' for an
instance of LlmModel" (PR #1239, Nextcloud#7).
The role does not need the companion user: verify.rb.j2 checks the binding
through LlmModel.enabled_chat_bot_ids, which v2026.10.0 still derives from
SiteSetting.ai_bot_enabled_llms, and the registration sets that setting.

Discourse AI is configured through an LlmModel row rather than settings, so the
addon upserts one via rails: provider open_ai, the gateway's chat-completions
URL, the model the gateway serves, and this role's virtual key. It then binds
that row to ai_default_llm_model and to the bot, because a model that exists
but is bound to nothing serves no surface.
llm_models.url is POSTed verbatim, so DISCOURSE_LITELLM_CHAT_ENDPOINT carries
the full /v1/chat/completions path rather than a base URL. Every other consumer
in this requirement takes a base and appends; getting this one wrong produces a
404 at prompt time, long after a green deploy.
Three things had to be cleared before any of that could work.
Discourse refuses to call a private address unless the host is in
allowed_internal_hosts, and it fails as an opaque provider error rather than as
a blocked request. The script appends the gateway host to that list and leaves
existing entries alone, which matters because the OIDC bootstrap in
config.yml.j2 appends the discovery host to the same pipe-separated setting.
Both sides check membership before adding, so they compose instead of
clobbering each other.
The launcher-managed container sits outside the compose graph and does not join
the gateway network on its own. handlers/stack_host.yml adds
DISCOURSE_LITELLM_NETWORK to its network list and config.yml.j2 passes the
matching --network flag, both only while litellm is enabled.
The bootstrap aborted before the plugin could install at all. after_code cloned
every enabled plugin unconditionally, but a bundled plugin already sits in
$home/plugins, git exits non-zero on the clone, and the whole bootstrap stops.
discourse-ai is bundled in current images, so it now skips plugins whose source
is bundled.
mem_limit goes from 2g to 4g. `rails r` boots a second Rails inside the
container already running unicorn and sidekiq, and at 2g the kernel kills it
mid-run: measured in deploy-036-11 and again in deploy-ai-v2-7, where the task
died with "Killed" and the deploy ended at exit 137. Upstream documents 4 GB as
Discourse's own minimum, so this corrects an under-provisioned limit rather than
working around the task. The variant resource budget still passes.
Verified: the OOM with the exact task and exit code across two independent runs,
the bundled-plugin abort, and that the budget test holds at 4g.
Not verified: the registration has never completed, because every attempt so far
died at the OOM first. The eight-fact read-back assertion and
addons/discourse-ai.spec.js are both entirely unexercised, the spec because the
addon bridge gate had it skipping.
