Add after_link_hook and vcon_hook extension points#157
Merged
Conversation
- conserver/after_link_hook.py: no-op called after every chain link
(success or error). main.py calls it with vcon_id, link_name, module,
options, status, error, and parties extracted from the vCon.
- api/vcon_hook.py: no-op called after vCon create (POST /vcon,
POST /vcon/external-ingress) and delete (DELETE /vcon/{uuid}).
- AUDIT_META stubs added to 11 built-in link modules so downstream
implementations can read service/data-type/transformation metadata
without hardcoding it per-link.
- All call sites wrapped in try/except so hook errors never affect
API responses or chain execution.
Both files are designed to be replaced at Docker build time by
downstream images.

opentelemetry-bootstrap -a install fails when auto-detected packages (e.g. opentelemetry-util-genai, opentelemetry-instrumentation-openai-v2) require a newer opentelemetry-api version than the one locked in uv.lock. The conflict is in transitive deps, not in packages we install directly. Adding || true lets the build succeed; instrumentation for packages that resolved cleanly continues to work.

Same fix as Dockerfile.api and Dockerfile.conserver — the combined dev/CI image also uses opentelemetry-bootstrap which fails on version conflicts between auto-detected packages. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Summary
conserver/after_link_hook.py— a no-op hook called after every chain link completes (success or error), with access tovcon_id,link_name, the link module, options, status, error, and parties. Called frommain.pyat both the success and error paths.api/vcon_hook.py— a no-op hook called after a vCon is created (POST /vcon,POST /vcon/external-ingress) or deleted (DELETE /vcon/{uuid}).AUDIT_METAstubs to 11 built-in link modules — a dict that downstream hook implementations can read for service name, data type, and transformation metadata without hardcoding it per-link.try/exceptso hook errors never affect API responses or chain execution.Both files are designed to be replaced at Docker build time by downstream images.
