Approval cards raised by company-mode internal scheduling turns (review/report
work items, session ids like `<root>:review::<wid>::vN`) were posted to the
turn's own session channel, which the UI deliberately hides. The card silently
timed out after 300s and the work item parked on AWAITING_HUMAN, so users saw
only the gate card and never the approval prompt. ws_handler now detects these
internal turns and routes their escalation cards to origin_task_id, the root
session's primary task channel, or the activity channel — never the hidden one.
Also unblocks the previously dead origin/session fallbacks in the resolver.
Unclassified LLM stream failures (e.g. provider content-filter rejections like
"input may contain sensitive information") used to hit a blind truncate-retry
loop that replayed the identical payload for a dozen-plus consecutive failures.
runtime_v2 now feeds the provider's verbatim error text back into the
conversation as a "[runtime notice]" system message so the model can adapt
(rephrase, drop quotes, change tack), bounded at 2 feedback retries (counter
resets on any successful stream) plus one context-reset attempt, then fails
honestly with the real error. The blind truncate path remains only for
classified tool-protocol errors.
Verified: new end-to-end tests for recover-after-notice and bounded-failure;
runtime_v2 + ws_handler + escalation/approval + company-mode suites all green.
