- resolveTelemetryPatch: extracted pure switch resolution (unit-tested);
fails loud when DSH_TELEMETRY_DISABLED is set but the row is absent, and
documents that ANY non-empty value (including '0'/'false') disables.
- runHeadless: SIGINT/SIGTERM now dispose the tree before exit so the
telemetry tail and shutdown marker drain (Node's default signal exit
skips disposal).
- web.cordis.yml: explicit maxQueueSize beside maxExportBatchSize (the
single-batch drain invariant no longer leans on an SDK default), comment
covers exportTimeoutMillis's role and links the Agent Note.
- apps/web scaffold: disable telemetry-otel — fixture sessions must never
leave the process.
- apps/cli README (en/zh + pairing): document the default endpoint, both
env seams, and the no-redaction disclosure.
Mount the existing telemetry seam + OTel logs backend in the web/headless
config tree so every session-log event streams to an OTLP/HTTP collector:
- telemetry-otel row: url defaults to the standard local OTLP endpoint,
DSH_TELEMETRY_OTLP_URL overrides; 10s batch cadence; exporter/processor
values bound the shutdown drain to ~1s against an unreachable collector
(timeoutMillis doubles as the retry deadline, single-batch drain).
- DSH_TELEMETRY_DISABLED opt-out: AppCLIEntry patches the row disabled
before boot (config alone cannot disable a row, and exporter.url
validation is load-time fail-loud).
