The debug-logger.ts module existed but was completely orphaned — none of
its functions had any callsites, so DISPATCH_DEBUG_LLM=1 did nothing.
Wires it in across the stack:
- llm/debug-logger.ts: add wrapFetchWithLogging() that tees SSE bodies via
TransformStream + response.clone() so we capture every chunk without
draining the body the AI SDK consumes. Redacts authorization / x-api-key
/ cookie headers in logs. Also exports nextDebugSeq() so requests and
log files share an id.
- llm/provider.ts: all 3 factories (Claude OAuth, plain-API-key Anthropic,
OpenAI-compatible) now pass fetch: wrapFetchWithLogging(globalThis.fetch).
For Claude OAuth the wrap goes on the inner base fetch so logged bodies
reflect the post-transform shape + Claude-Code session headers. Added
tabId to ProviderConfig for log labelling.
- agent/agent.ts: threads tabId through createProvider and emits
logAgentLoop / logStepLifecycle / logStreamEvent at every meaningful
point in the run loop — step start/end, tool count, every fullStream
event. All are no-ops when DISPATCH_DEBUG_LLM is unset.
- core/index.ts: re-exports the debug helpers.
- tests/llm/provider.test.ts: switch one full-object equality assertion
to property assertions so the test survives the new fetch: wrapper.
Plumbing the env var into the container required three more fixes:
- bin/up: re-export DISPATCH_DEBUG_LLM* so docker compose forwards them
(compose only forwards vars referenced in the environment: block).
Also pre-creates /tmp/dispatch/llm-debug and chowns it on first run so
the container's UID-1000 bun process can write into it without EACCES.
- docker-compose.yml: declare the debug vars on api.environment and
bind-mount /tmp/dispatch/llm-debug:/tmp/dispatch/llm-debug so logs are
inspectable from the host without docker exec.
- docker/entrypoint.dev.sh: explicitly forward DISPATCH_DEBUG_* through
the 'su -' login-shell barrier — su - resets the environment to TERM/
PATH/HOME/SHELL/USER/LOGNAME only, silently stripping everything else.
This is why the vars appeared via 'docker exec env' (which spawns a
new process inheriting the container env) but were absent from the
actual bun process's /proc/<pid>/environ.
bin/build: drop stray sudo for consistency with bin/up and bin/down.
