Restore the shipped payload-first contract from #3464/#3495 and the explicit source #3755 scope clarification. Two provider conversations must retain distinct IDs despite an inherited registered ECC parent ID. Normal and ambient producer24 tests, canonical resolver10 and independent differential review pass. Keep native importer guards; explicit provider/native correlation is queued separately.
Verify review discussion4419348312 against actual native producer/importer behavior. Prefer the independently sanitized ECC_SESSION_ID for the ECC-owned metrics feed, retain payload then legacy fallback for standalone hooks, and leave sibling hooks unchanged.
Actual Node producer plus read-only cached native binary reproduces zero imported metrics before the fix and exactly one tool/file/log after repeated sessions/status commands. Four producer regression controls and normal/adversarial inherited-env suites pass22/22. Focused coverage96.47percent lines and91.47percent branches; parent independent source review passed.
session-activity-tracker.js is correctly registered in
posttooluse-dispatcher.js's SYNC_HOOKS and fires on every tool call --
but buildActivityRow() only ever read the session id from
ECC_SESSION_ID/CLAUDE_SESSION_ID environment variables, which Claude
Code does not actually set for hook subprocesses. Every row silently
came back null and nothing was ever written to
~/.claude/metrics/tool-usage.jsonl, with no error anywhere.
The session id is available in the hook's own stdin JSON payload
(input.session_id) in real invocations. This prefers that, keeping the
env vars as a fallback. New test added; all 18 existing + new tests
pass.
Also adds a live Activity view to the capabilities dashboard
(scripts/dashboard-web.js) reading that same metrics file, so Skill
vs. Agent vs. raw-tool usage is visible in real time instead of
requiring a manual tail+jq -- verified live against a real session
before this commit. Documents the loopback-only, no-auth design and
the standard SSH-port-forwarding pattern for viewing it from another
device you control.
