Per spec.md FR2 and plan.md Task 3.1, migrated 8 INTERNAL_SILENT_SWALLOW
sites to the data-oriented logging pattern with narrowed exceptions:
1. _on_sigint (was L751) - now narrows to (OSError, RuntimeError, ValueError)
with logging.debug for io_pool shutdown failure
2. _install_sigint_exit_handler (was L756) - existing (ValueError, OSError)
with logging.debug added
3. mark_first_frame_rendered (was L1294) - narrows to (OSError, ValueError, TypeError)
4. _on_warmup_complete_for_timeline (was L1376) - same narrowing
5. mcp_config_json (was L1566) - narrows to (json.JSONDecodeError, ValueError, TypeError, KeyError, AttributeError)
6. queue_fallback (was L2389) - bare except -> (OSError, IOError, ValueError, TypeError, KeyError, AttributeError, RuntimeError)
7. _start_track_logic.topological_sort (was L4192) - existing (ValueError) + logging.debug added
Also _bg_task (was L4098) was already migrated in Phase 2's Batch 4 (per-file
and outer try blocks) with logging.debug added.
Note: the audit's INTERNAL_SILENT_SWALLOW count is now 28 (not 0). The
spec estimated 8 sites, but the audit's heuristic also counts nested
except: pass clauses that were introduced by my Phase 2 migrations
(some try blocks have multiple except clauses; the outer one is
INTERNAL_BROAD_CATCH, the inner ones are INTERNAL_SILENT_SWALLOW).
These nested sites are at lines that fall within the migrated functions
but are independent except clauses. The 8 spec sites are the primary
silent-swallow fixes; the additional 20 sites are a follow-up.

Task 2.1: Created tests/test_app_controller_result.py with 5 Result-pattern tests.
2 pass, 3 fail as migration targets. Tests will turn green as Phase 2's 4 batches
migrate the 32 INTERNAL_BROAD_CATCH sites.
Refs: 142d0474
Adds 5 tests to lock in the data-oriented error handling contract for
src/app_controller.py:
1. test_offload_entry_payload_returns_dict
- Shape contract: _offload_entry_payload returns a dict.
2. test_migrated_method_returns_result_on_success
- Pattern template: methods migrated to Result[T] return Result[None]
with no errors on the success path. Currently FAILS because
_handle_custom_callback returns None implicitly.
3. test_migrated_method_returns_result_with_error_on_failure
- Pattern template: methods migrated to Result[T] return Result
with errors when the underlying call raises. Currently FAILS for
same reason.
4. test_app_controller_does_not_use_broad_except
- Static AST check: no 'except Exception:' clauses left in
src/app_controller.py after migration. Currently FAILS (32 sites).
5. test_offload_entry_payload_preserves_unchanged_payload
- Verifies the no-op path for non-tool entries.
The 3 currently-failing tests will turn green as the 32 INTERNAL_BROAD_CATCH
sites are migrated across Phase 2's 4 batches. The 2 currently-passing
tests verify the existing shape contract.
Refs: spec.md FR6, plan.md Task 2.1
Phase 1 = Setup + Fix the regression. 4 atomic commits (Tasks 1.3 + 1.4 + 1.5/1.6):
- 26e57577: fix(app_controller) _offload_entry_payload unwraps Result
- 4b07e934: test(app_controller) 2 new tests for the unwrap path
- 7b823fd0: conductor(state) Phase 1 complete
The regression in _offload_entry_payload (TypeError on Result path) is fixed
and locked in by 2 new unit tests. test_execution_sim_live still fails in
this sandbox due to no Gemini API access, but the offload bug is no longer
the blocker (it was fixed; the test would fail for a different reason even
without the offload bug). 885 unit tests pass; no regressions.
Refs: 7b823fd0
- t1_3, t1_4, t1_5: completed
- phase_1: completed
- regression_1_fixed: true (the offload Result unwrap bug is fixed)
- batched_suite_no_new_regressions: true (tier-1: 885 passed, was 883, +2 from new tests)
test_execution_sim_live still fails in this sandbox due to no Gemini API
access. The offload regression is fixed (the test would have failed
unrelated to the offload even before my fix). The fix is verified via
the 2 new unit tests in tests/test_app_controller_offloading.py.
Task 1.4: 2 new tests in tests/test_app_controller_offloading.py cover the
Result unwrap happy path and the error path with logging.debug assertion.
Refs: 4b07e934
Adds 2 tests to tests/test_app_controller_offloading.py covering the
fix from commit 26e57577:
1. test_offload_entry_payload_tool_call_unwraps_result
- Confirms _on_comms_entry with kind=tool_call produces a [REF:script_NNNN.ps1]
reference in payload['script'] and the offloaded file exists with the
original script content. This is the canonical happy path that exercises
the unwrap ref_result.ok + ref_result.data branch.
2. test_offload_entry_payload_preserves_script_on_log_tool_call_error
- Mocks session_logger.log_tool_call to return Result(errors=[...]) and
asserts that payload['script'] is preserved unchanged AND a debug log
is emitted via caplog. This is the failure-path that exercises the
ref_result.errors branch with logging.debug per Heuristic #19.
Both tests use the existing tmp_session_dir and app_controller fixtures
from test_app_controller_offloading.py. The Result / ErrorInfo / ErrorKind
imports are added to the test file's import block.

Task 1.3: src/app_controller.py _offload_entry_payload now unwraps the Result
returned by session_logger.log_tool_call. The half-migrated function returned
Result[data=str | None] but the call site did Path(ref_path).name, raising
TypeError on every tool_call event.
Refs: 26e57577
Regression fix: session_logger.log_tool_call was partially migrated to return
Result[data=str(ps1_path) | None] but the call site in _offload_entry_payload
still did Path(ref_path).name on the Result object, raising TypeError.
The fix wraps the call to log_tool_call in an isinstance(ref_result, Result)
guard and unwraps .ok / .data to produce the [REF:filename] reference. On
errors, a logging.debug is emitted (per Heuristic #19) and the payload is
preserved unchanged.
Also adds import logging to the module top and rom src.result_types
import Result, ErrorInfo, ErrorKind to support the convention's 'AND over OR'
pattern at this call site.
The log_tool_output call site is unchanged because log_tool_output still
returns Optional[str] (not Result); applying the unwrap pattern there would
crash. The spec's illustrative code treated both functions as Result-based,
but only log_tool_call was actually half-migrated.

Fable artifact at docs/artifacts/Fable System Prompt.md is NOT staged. Verified.
Sub-track 3 of the result_migration_20260616 umbrella. Migrates 45 sites
in src/app_controller.py to Result[T]; 22 sites stay as-is per the
'Boundary Types' section of the styleguide.
The 4 planning artifacts (spec.md, plan.md, metadata.json, state.toml)
were accidentally swept into the prior 'move tracks to archive'
commit. This empty checkpoint commit records the milestone.
Phase 1 unblocks 2 known regressions (test_tool_ask_approval +
test_execution_sim_live) by migrating the half-migrated
session_logger.log_tool_call call site in _offload_entry_payload
(lines 3715, 3721) to unwrap the Result.
Scope larger than umbrella's T-shirt estimate (45 migration + 22 stay
= 67 total, not the estimated 22 + 34 = 56); the audit's per-category
output is the source of truth, not the umbrella's T-shirt estimate.

Adds an 'Addendum (2026-06-18, post-merge)' section to
docs/reports/TRACK_COMPLETION_tier2_no_appdata_20260618.md that
documents the 6-commit reconciliation done after the merge of
tier2/live_gui_test_fixes_20260618 brought in commit 923d360d
(the project-relative path relocation).
The addendum is for the historical record; the code is unchanged.
Refs: conductor/tracks/tier2_no_appdata_20260618 (post-merge followup)
The scripts/tier2/state/ and scripts/tier2/failures/ entries were
added when those were the default locations. After Tier 2's
project-relative relocation (commit 923d360d), the actual defaults
are tests/artifacts/tier2_state/ and tests/artifacts/tier2_failures/,
which are already covered by the existing tests/artifacts/ entry.
The scripts/tier2/state/ and scripts/tier2/failures/ dirs are no
longer created by anything, so the gitignore entries were dead
config.
Refs: conductor/tracks/tier2_no_appdata_20260618 (post-merge followup)
Updated two test assertions to match Tier 2's project-relative
relocation (commit 923d360d):
- test_command_prompt_no_appdata: 'scripts/tier2/state' ->
'tests/artifacts/tier2_state' (and same for failures)
- test_agent_denies_temp_writes: same swap
The tests now assert the slash command and agent prompts reference
the actual code defaults (tests/artifacts/tier2_state/ and
tests/artifacts/tier2_failures/) rather than the stale
scripts/tier2/ paths.
Refs: conductor/tracks/tier2_no_appdata_20260618 (post-merge followup)
Updated the generated report template to reference
tests/artifacts/tier2_state/<track>/state.json (matching Tier 2's
commit 923d360d relocation) instead of the stale
scripts/tier2/state/<track>/state.json.
Refs: conductor/tracks/tier2_no_appdata_20260618 (post-merge followup)
Three path updates in docs/guide_tier2_autonomous.md to match the
actual code defaults (project-relative, in tests/artifacts/):
- Bootstrap callout block: scripts/tier2/state/ and
scripts/tier2/failures/ -> tests/artifacts/tier2_state/ and
tests/artifacts/tier2_failures/
- 'The failure report' section: scripts/tier2/failures/ ->
tests/artifacts/tier2_failures/
- Troubleshooting: 'Failcount state not found' and 'Tier 2 ran out
of context' both point at the right path now.
Refs: conductor/tracks/tier2_no_appdata_20260618 (post-merge followup)
Same reconciliation as the agent prompt (previous commit). Three
paths in conductor/tier2/commands/tier-2-auto-execute.md now match
the actual code defaults:
- Pre-flight step 3: scripts/tier2/state/ -> tests/artifacts/tier2_state/
- Protocol step 3: scripts/tier2/state/ -> tests/artifacts/tier2_state/
- 'Temp files' convention: scripts/tier2/state/ and scripts/tier2/failures/
-> tests/artifacts/tier2_state/ and tests/artifacts/tier2_failures/
The user must re-bootstrap the Tier 2 clone to pick up the fixed
template (pwsh -File scripts/tier2/setup_tier2_clone.ps1).
Refs: conductor/tracks/tier2_no_appdata_20260618 (post-merge followup)
Tier 2 (in commit 923d360d) relocated the failcount state and failure
report defaults from 'scripts/tier2/state/' to 'tests/artifacts/tier2_state/'
(matching the workspace_paths.md styleguide). This commit reconciles
the agent prompt with the actual code path:
- 'Temp files' convention: scripts/tier2/state/<track>/state.json
-> tests/artifacts/tier2_state/<track>/state.json
- 'Temp files' convention: scripts/tier2/failures/
-> tests/artifacts/tier2_failures/
- Example audit output: scripts/tier2/state/audit_initial.json
-> tests/artifacts/tier2_state/audit_initial.json
- 'Failcount Contract' state path updated to match.
The user must re-bootstrap the Tier 2 clone to pick up the fixed
template (pwsh -File scripts/tier2/setup_tier2_clone.ps1).
