[codex] Add progress outcome canary

[OmarB97]

Summary

• add a turn-level progress outcome canary that watches tool rounds, not just individual tool families
• inject one synthetic progress nudge after repeated tool rounds with no observable work outcome
• record progress canary metadata in the run result and logs, while staying quiet after landed file mutations or state-changing commands

Root Cause

The search/read/terminal guardrails catch known local loop shapes, but an agent can still burn several tool rounds doing plausible-looking diagnostics without producing a concrete outcome. There was no higher-level assertion that a turn had made an edit, changed durable state, opened/updated workflow state, or deliberately changed strategy.

Validation

• ./scripts/run_tests.sh tests/run_agent/test_tool_call_guardrail_runtime.py tests/agent/test_tool_guardrails.py tests/tools/test_read_loop_detection.py
• python -m ruff check agent/progress_outcome.py agent/agent_init.py agent/conversation_loop.py run_agent.py tests/run_agent/test_tool_call_guardrail_runtime.py
• git -c core.fsmonitor=false diff --check

[OmarB97]

Rebased this upstream mirror onto current main and repaired the CI fallout. Current head: fd0dfeebb was superseded by 33d9162b0, final head is 33d9162b0527d6593d69b209fb0ea567238fa4e7. Local verification passed: scripts/run_tests.sh tests/test_run_tests_parallel.py tests/run_agent/test_vision_tool_messages.py tests/agent/test_local_stream_timeout.py tests/run_agent/test_streaming.py tests/tools/test_file_tools.py -- -q plus py_compile/diff-check on the touched runner/Docker tests. GitHub is now CLEAN/MERGEABLE with all checks green, including all six test shards, typechecks, Nix, Docker amd64/arm64, lint, attribution, and common-ancestor. Merge attempt through meshctl pr merge was blocked only by GitHub permission: OmarB97 cannot execute MergePullRequest on this upstream repo.

Refreshed onto upstream/main (rebase, live merge-base c9a150d640). One conflict: agent/chat_completion_helpers.py had an add/add collision where upstream's new cross-turn stale-call circuit breaker (_stale_streak/_check_stale_giveup, #58962) and this PR's new resolve_stream_stale_timeout/dflash-timeout helpers both inserted at the same blank-line location — resolved by keeping both blocks side by side (no logic overlap; verified call sites for both features are still wired correctly through interruptible_api_call/interruptible_streaming_api_call). Original head 991aebddbb -> refreshed 113c3406b1. Content unchanged vs original diff (33 files, +3370/-88 vs original +3372/-88 — the 2-line delta is dedup of the conflict-marker region itself). Focused tests green: test_stall_retry.py + test_chat_final_response_resilience.py (16 passed). Checks re-running.

Thanks for targeting the remaining gap between per-tool repetition checks and a turn-level lack of outcome. The premise remains present on current main: agent/tool_guardrails.py:350-375 only tracks repeated results for the same idempotent call signature.

Problems

• agent/conversation_loop.py:4888-4892 appends a synthetic user message after tool execution. This violates the strict alternation invariant in AGENTS.md:88-91, which explicitly prohibits synthetic user messages mid-loop.
• agent/stall_retry.py:271-272 independently constructs a synthetic assistant/user pair for retry, creating the same invalid in-turn transcript shape.
• agent/stall_retry.py:20-28 adds user-facing non-secret HERMES_STALL_RETRY_* settings; AGENTS.md:102-107 requires behavioral settings to use config.yaml instead.
• The 33-file diff also includes dflash retry/model switching, result compaction, timeout, MeshBoard routing, and file-tool work beyond the stated canary.

Suggested changes

• Attach the canary guidance to an existing tool result instead of appending a user message, and add an end-to-end role-alternation test.
• Remove or separately redesign the retry transcript mutation.
• Keep user-facing settings in config.yaml and split unrelated feature work from the canary.

This appends a synthetic user turn after a tool batch in the active loop. AGENTS.md:88-91 explicitly prohibits synthetic user messages mid-loop to preserve role alternation and prompt-cache invariants. Attach the advisory to an existing tool-result message instead, and cover the resulting transcript shape end to end.

[teknium1]

This retry path independently creates a synthetic user turn in the current conversation payload. It has the same role-alternation problem as the canary injection; a retry mechanism must preserve the transcript roles rather than append an assistant/user pair mid-turn.

These are user-facing non-secret behavior controls. Project policy requires timeouts, thresholds, flags, and similar settings to live in config.yaml, not new HERMES_* environment variables. Keep the config mapping and remove these env overrides.
