The .usage.json file is owned by hermes-agent (tools/skill_usage.py).
This change removes the webui-side increment logic to avoid:
1. File ownership conflict - both writing to same file
2. Schema mismatch - agent uses ISO strings, webui used floats
3. Concurrency issues - agent uses fcntl locks, webui had no locking
4. Double-counting - agent already increments counters server-side
Changes:
- api/skill_usage.py: keep only read_skill_usage(), remove increment functions
- api/streaming.py: remove skill usage counter hook
- api/routes.py: adapt response to pass through agent's format as-is,
with defensive coercion for None values and metadata preservation
- tests/test_skill_usage.py: remove increment tests (17→7 cases)
Use _merged_session_messages_for_display for is_messaging_session even in the
metadata-only (messages=0) path. This ensures message_count and last_message_at
match the full load path for Telegram / external messaging sessions that have
stitched or duplicate rows in state.db + sidecar.
Prevents spurious refresh loops, scroll resets, and open panel closures when
resuming cross-surface sessions in the WebUI.
No impact on CLI, non-messaging, or full-message paths. All 580 session tests pass.
Fixes the root cause identified in the SessionDB / render interaction changes.
The 7 other tests in this file deterministically cover the supervisor invariants
(concurrent spawn, timeout-race reap, Popen-failure recovery, supervisor singleton).
This 1 test depends on bash prompt rendering + printf execution echoing through
the PTY within a 1s deadline, which is timing-flaky in non-tty CI.
Replace the hardcoded 4-option deliver dropdown (local/discord/telegram/slack)
with a dynamic select populated from a new GET /api/crons/delivery-options
endpoint that reads _KNOWN_DELIVERY_PLATFORMS from hermes-agent.
Key changes:
- Add GET /api/crons/delivery-options endpoint returning all known platforms
- Frontend loads options asynchronously on first cron form open, with caching
- Enable deliver editing for existing jobs (was previously disabled)
- Include deliver in update payload when editing cron jobs
- Fallback to local-only if API unavailable
- Custom deliver values (e.g. feishu:oc_xxx) shown with * suffix
- Add cron_deliver_custom i18n key to all 12 locales
- Add 5 integration tests for the new endpoint
* Comment alongside _AUTH_FINGERPRINT_VOLATILE_KEYS notes client_secret
is treated as rotation-only on purpose, not a model-cache
differentiator (maintainer §Concerns 3).
* _write_auth docstring at tests/test_issue_t16551f61_auth_token_churn_
fingerprint.py:108 now describes actual behavior (writes + monkeypatch,
no sleep+restat) — Copilot r3302471228.
