Per user question about whether execution is properly isolated between
AppController and gui_2.py main thread.
Verified by reading the architecture contract (docs/guide_architecture.md
lines 12, 884-890) and the two click handlers in question:
- _handle_generate_send (btn_gen_send): self.submit_io(worker)
- _cb_plan_epic (btn_mma_plan_epic): self.submit_io(_bg_task)
BOTH click handlers return immediately after submitting work. The
heavy AI call (ai_client.send -> subprocess.Popen -> process.communicate)
runs on the io_pool worker thread. The execution isolation between
AppController and gui_2.py's main render thread IS being followed.
The crash (STATUS_STACK_OVERFLOW, 0xC00000FD) is NOT in the click
handler chain. It IS in the main thread's imgui-bundle render loop.
The render loop runs concurrently with the io_pool worker's subprocess
operations. imgui-bundle's per-frame C++ draw code can exceed the main
thread's 1.94 MB stack (verified via kernel32.GetCurrentThreadStackLimits).
What aspect of negative_flows triggers this: the error-response render
path. MOCK_MODE=malformed_json causes the adapter to raise, which
triggers _handle_request_event to emit a 'response' event with
status='error'. The render loop draws this error response on the next
frame, exhausting the main thread's stack.
test_visual_orchestration.py uses the same provider setup but does NOT
set MOCK_MODE, so the mock defaults to 'success' mode, the adapter
returns normally, no error event, no crash. Empirically PASSED in
11.01s.
The architecture's render-loop contract assumes imgui-bundle's C stack
usage is bounded. It's not. The architecture has no enforcement
mechanism (no stack guard, no per-frame stack measurement, no graceful
degradation).
Next step (post-compact): capture Windows crash dump via procdump to
identify the specific imgui-bundle draw call.
User asked why this test is uniquely affected. Answer: it's the ONLY
tier-3 test where the AI call runs ASYNCHRONOUSLY in the io_pool worker
while the imgui-bundle render loop continues on the main thread.
Verified: test_visual_orchestration.py::test_mma_epic_lifecycle uses
the same provider setup (gemini_cli + mock_gemini_cli.py + click) but
calls orchestrator_pm.generate_tracks() synchronously in the main
thread, blocking the render loop. It PASSES in 11s.
test_mma_step_mode_sim.py::test_mma_step_mode_approval_flow also uses
the async path but is @pytest.mark.skipif(not RUN_MMA_INTEGRATION) -
skipped by default. Would likely also crash if unsuppressed.
All other MockProvider tests short-circuit at ai_client.send and never
spawn a subprocess.
The crash is on the MAIN thread (1.94 MB stack, verified via
kernel32.GetCurrentThreadStackLimits), not the io_pool worker (which
has 8MB after threading.stack_size(8MB) patch). The main thread's
imgui-bundle render loop runs concurrently with the io_pool worker's
subprocess.Popen / process.communicate. The accumulated imgui-bundle
C++ frames exhaust the main thread's 1.94 MB stack.
This explains:
- Why bumping io_pool stack to 8MB doesn't help (the patch can't reach
the main thread, which was created before any sitecustomize runs).
- Why the standalone subprocess call works (no render loop concurrent).
- Why the no-click baseline survives 60s (no AI call to trigger the race).
Next step: capture a Windows crash dump via procdump or cdb.exe to
confirm the crashing thread is the main thread and identify the
specific imgui-bundle C++ stack frame.
The Tier 2 sandbox blocks git push (and all other destructive git ops).
After Tier 2 finishes a track, this script is the bridge: it fetches the
tier2/<track> branch from the sandboxed clone (C:\projects\manual_slop_tier2)
into the main repo (C:\projects\manual_slop), creating a local
review/<track> branch so the working tree is untouched.
Usage:
pwsh -File scripts\\tier2\\fetch_tier2_branch.ps1 -TrackName send_result_to_send_20260616
Supports -WhatIf for dry-run. Does NOT push to origin (user's call).
End-of-track report following the same format as
TRACK_COMPLETION_tier2_autonomous_sandbox_20260616.md. Documents:
- 24-commit inventory (10 atomic renames + 14 plan/script commits)
- All 6 phases completed, all 9 verification flags = true
- Pre-existing failures (7 tests, all credentials.toml, confirmed
against origin/master baseline where they also fail)
- 2 surgical doc fixes in error_handling.md (deprecation section +
line 204 contradiction)
- Sandbox enforcement contracts held (4 of 4 hard bans + 4 of 4
secondary contracts)
- User handoff instructions (fetch + diff + merge + per-commit review)
The track is the first end-to-end test of the tier2_autonomous_sandbox;
this report is the final deliverable for that test.
Phase 6 tasks (t6_1, t6_2, t6_3) and the phase itself marked completed.
All 16 task entries now have status=completed.
All 6 phase entries now have status=completed.
This is the final state.toml commit for the track.
Track marked shipped 2026-06-17. All 6 verification criteria evaluated
with PASS/EXCEEDED/READY status and notes. 7 pre-existing test failures
documented with root cause and pre_existing_failures_remaining flag.
Risk register updated: scope_creep=none, behavior_change=none,
doc_drift=medium (error_handling.md deprecation section required
surgical rewrite to historical note).
No deferred_to_followup_tracks (this track completed cleanly).
Final grep: 0 send_result in active code. 3 historical refs in
error_handling.md (intentional, in the 'Historical deprecation' note).
Test verification: 100/101 tests pass in the 26 files renamed by this
track. 1 pre-existing failure in test_headless_service.py due to
missing credentials.toml (verified against origin/master baseline
where it also fails - unrelated to the rename).
Final grep: 0 send_result in active code. 3 historical refs in
error_handling.md (intentional, in the 'Historical deprecation' note).
Test verification: 100/101 tests pass in the 26 files renamed by this
track. 1 pre-existing failure in test_headless_service.py due to
missing credentials.toml (verified against origin/master baseline
where it also fails - unrelated to the rename).
7 broader suite failures all pre-existing (all FileNotFoundError on
credentials.toml, confirmed against origin/master baseline).
Track verification:
- git grep send_result: 0 in active code (3 historical intentional)
- Full test suite: matches pre-rename baseline (7 pre-existing failures
unrelated to the rename, 0 new regressions)
Doc consistency: guide_ai_client.md, guide_app_controller.md, and
the error_handling styleguide now reference the new symbol name.
Also fixes two consistency issues in error_handling.md introduced by
the mechanical rename:
1. The 'Deprecation: send -> send_result' section (lines 623-642) was
rewritten as a 'Historical deprecation (added 2026-06-15, reverted
2026-06-16)' note that points to the relevant track specs.
2. Line 204 (the 'Current State Audit' summary for src/ai_client.py)
had a self-contradictory claim ('send() is the new public API;
send() is @deprecated') after the rename. Updated to describe
the canonical public API.
Historical archives (conductor/tracks/*/spec.md, conductor/tracks/*/plan.md,
docs/reports/*) are NOT modified - they document the 2026-06-15
public_api_migration decision and stay as historical record.
Batch rename of 22 test files. 62 references renamed total.
The full test suite is now GREEN again, matching the pre-rename baseline
from Task 1.1. Pure mechanical rename. No behavior change.
Files affected: test_ai_cache_tracking, test_ai_client_cli,
test_ai_client_result, test_api_events, test_context_pruner,
test_deepseek_provider, test_gemini_cli_* (3 files), test_gui2_mcp,
test_headless_* (2 files), test_live_gui_integration_v2,
test_orchestration_logic, test_phase6_engine, test_rag_integration,
test_run_worker_lifecycle_abort, test_spawn_interception_v2,
test_symbol_parsing, test_tier4_interceptor, test_tiered_aggregation,
test_token_usage.
Note: spec estimated 24 files; actual is 22 (test_deprecation_warnings
no longer exists, and 1 fewer file than spec's list).
Refs: conductor/tracks/send_result_to_send_20260616/
Renames 10 references across app_controller, conductor_tech_lead,
mcp_client (docstring example), multi_agent_conductor, orchestrator_pm.
5 call sites in ai_client.send_result(...) -> ai_client.send(...)
3 print strings mentioning send_result
1 docstring comment (conductor_tech_lead)
1 docstring example (mcp_client) 'src.ai_client.send_result' -> 'src.ai_client.send'
Test suite state: still red, but all src/-level call sites are now
renamed. Remaining failures are in test files (mocks and patches
that still reference send_result).
Refs: conductor/tracks/send_result_to_send_20260616/
The TDD red moment. The implementation is renamed but the call sites
in src/, tests/, and docs still use send_result. Subsequent commits
rename the call sites and progressively move the test suite back to
green.
10 references renamed in src/ai_client.py:
- 4 'Called by: send_result' docstring tags in private provider helpers
- 1 function definition (def send_result -> def send)
- 1 [C: ...] SDM tag referencing test function names
- 2 monitor component names (start_component / end_component)
- 2 error source strings (CONFIG + INTERNAL)
Also adds scripts/tier2/apply_t1_1_edits.py - the helper script that
applied the 10 edits. Kept in scripts/tier2/ as a record of the
mechanical change pattern.
Refs: conductor/tracks/send_result_to_send_20260616/
The previous exclusion list had 'gemini_native' which is
NOT a real function name in src/ai_client.py. The actual
function is _send_gemini_cli (already migrated to
run_with_tool_loop via send_func + on_pre_dispatch in
commit 4748d134).
The current deferred vendors are now correctly:
- anthropic (uses anthropic SDK)
- gemini (uses google-genai streaming)
- deepseek (uses requests.post)
These will be addressed in Phase 5 t5_6/7/8. When those
ship, the DEFERRED_VENDORS frozenset should be emptied
so the audit gates the migration.
Verified: script still passes; gemini_cli's run_with_tool_loop
usage is detected correctly.
Phase 2 task 2.4 (the script part). The script enforces:
PROVIDERS is declared as a literal only in src/ai_client.py.
The __getattr__ re-export in src/models.py is allowed (it
lazy-imports, not a literal declaration).
Catches the literal pattern 'PROVIDERS: List[str] = ['
specifically, which the __getattr__ re-export does not
match.
OK: passes against current state where PROVIDERS is
declared only in src/ai_client.py:56.
Task 1.8 (the plan's numbering: 'Add audit script'). Audit checks
that no _send_<vendor> in src/ai_client.py contains an inline
'for round_idx in range(MAX_TOOL_ROUNDS' loop. The audit excludes
the 4 vendored-call-path vendors (anthropic, gemini, gemini_native,
deepseek) which are documented in state.toml's deferred_work
section as future work (they use their own SDKs and need
separate per-vendor conversion to OpenAICompatibleRequest).
state.toml:
- t1_7 (Apply to 4 inline-loop vendors): completed for
_send_gemini_cli only. Anthropic + Gemini + DeepSeek deferred.
- t1_8 (Add audit script): in_progress.
- t1_7 reuses commit 4748d134 (the send_func + on_pre_dispatch
refactor that introduced the new helper pattern for
vendored call paths).
OK: audit passes against the current 4 OpenAI-compat vendors
(minimax, grok, llama, qwen still uses _dashscope_call but
has no inline loop) + gemini_cli.
