The fix in 644d88ab changed the recovery path from client.delete_collection
to shutil.rmtree (chromadb 1.5.x delete_collection is broken on corrupted
state). The test still asserted the old behavior.
The wipe path called self._init_vector_store() which re-invoked
_validate_collection_dim, causing infinite recursion (RecursionError)
when the dim mismatch test ran with the mock embedding provider.
Re-initialize the vector store INLINE after the rmtree wipe so the
fresh collection is created without going through the validator
again.
When the existing collection has embeddings from a different
embedding provider (e.g. Gemini 3072-dim vs local 384-dim), the
prior approach of calling client.delete_collection() fails with
'RustBindingsAPI object has no attribute bindings' in chromadb 1.5.x
when the underlying state is corrupted. rmtree is reliable and
re-creates a fresh empty collection.
Also fixes:
- 'The truth value of an empty array is ambiguous' on numpy 2.x
by using try/except around len() instead of truthiness check
- WinError 32 on rmtree by closing the chroma client first
Verified: tests/test_rag_phase4_final_verify.py passes in isolation
in 7.75s after this fix. The test still fails in batch context due
to a separate io_pool race condition (multiple _sync_rag_engine
calls collide when the test sets rag_enabled, rag_source, and
rag_emb_provider in sequence). The race is in app_controller.py
and is out of scope for this defensive fix.
Note: tests/test_rag_engine.py has explicit unit tests for
test_rag_collection_dim_mismatch_recreates_collection and
test_rag_collection_dim_match_preserves_collection which
exercise this code path.
One addition to conductor/code_styleguides/python.md §8
"AI-Agent Specific Conventions":
- **No diagnostic noise in production code (Added
2026-06-09).** `sys.stderr.write(f"[XYZ_DIAG] ...") lines
in src/*.py are technical debt. The right place for
one-time investigation output is tests/artifacts/<test>.diag.log
(a log file) or a standalone /tmp/diag_<name>.py script.
If you must instrument production code, the diag lines
are part of the same atomic commit as the fix.
- **Test files ARE allowed to be diagnostic.** The rule
applies to src/*.py only; tests/test_*.py may use
print(..., file=sys.stderr) freely.
Markdown only. No code modified.
Two additions to conductor/workflow.md §"Known Pitfalls":
1. **Isolated-Pass Verification Fallacy (Added 2026-06-09)** —
the rule that a test passing in isolation but failing in
batch is FAILING. The only verification that matters for
live_gui tests is the batch run. This is the flip side of
the existing "Live_gui Test Fragility (Authoring-Side)"
rule. Cross-references that rule.
2. **Process Anti-Patterns (Added 2026-06-09)** — 8-rule
summary list, with cross-reference to AGENTS.md for the
full ruleset. The 8 patterns are: Deduction Loop,
Report-Instead-of-Fix, Scope-Creep Track-Doc,
Inherited-Cruft, Diagnostic Noise in Production, Premature
Surrender, Verbose Commit Message, Isolated-Pass
Verification Fallacy.
Markdown only. No code modified. Cross-references
AGENTS.md (the load-bearing agent doc) for the full text
of each pattern.
Three surgical fixes to conductor/edit_workflow.md:
1. **§2 "Verify Before Editing"** — removed the leftover
`git checkout -- src/gui_2.py` instruction. The user's
commit `4eba059e unfuck edit workflow` removed most of
the git checkout nuke instructions but missed §2. The
revised §2 now says: read the contract (function signature,
yield shape, return type) before editing, and DO NOT use
`git checkout` to revert. Ask the user.
2. **§3 "Reading Before Editing"** — added the line-number
offset check. `set_file_slice` uses 1-indexed inclusive
`start_line`/`end_line`; off-by-one is a common silent
failure. The rule is now: confirm the exact line range
with `get_file_slice` first.
3. **§8 "set_file_slice IS Valid for Multi-Line Content
(Revised 2026-06-09)"** — replaced the wrong rule
("Do not use set_file_slice for multi-line content") with
the correct rule: set_file_slice IS valid for 3-10 line
surgical edits, with a tool-selection guide (which tool
for which job), a mandatory contract-change check
(search for callers of the symbol being changed; update
all callers in the same atomic commit if the public
interface changes), and a mandatory whitespace-and-EOL
rule (preserve line ending, indentation, and line count).
4. **§9 "No Diagnostic Noise in Production Code
(Added 2026-06-09)"** — new section. Diag stderr goes
to log files or /tmp scripts, NOT src/*.py. If you must
add diag lines to production code, they are part of the
same atomic commit as the fix — they do not live
uncommitted in the working tree.
5. **"If set_file_slice produces wrong indentation"** —
new handler in the Step-by-Step Workflow. Tells the
agent: you wrote the wrong indent; the tool did what
you asked; re-read the file with get_file_slice; do
NOT use git checkout to revert.
These are the rule corrections the user demanded after
the Tier-2's bad set_file_slice + git nuke + diag-noise
behavior. Markdown only. No code modified.
The user explicitly called out the bad patterns the agents
(Tier-2 and the parent session's Tier-1) have been exhibiting.
This commit updates AGENTS.md to filter them out at the
load-bearing agent doc level (the first file any agent reads).
Three changes:
1. **Revised the `set_file_slice` rule on line 38** of the
Critical Anti-Patterns. The previous rule said "Do not use
set_file_slice for multi-line content" — that was wrong.
`set_file_slice` IS valid for multi-line content, provided
the agent verifies the exact byte offsets with `get_file_slice`
and checks for contract changes (function signature, yield
shape, return type). The full revised rule is in
`conductor/edit_workflow.md §8`.
2. **Added "No diagnostic noise in production code"** to the
Critical Anti-Patterns. The pattern: agent adds
`sys.stderr.write(f"[RAG_DIAG] ...") to src/*.py` for
debugging, then "reverts everything" but leaves the diag
lines uncommitted. Next agent runs git status, sees the
diag lines, either commits them by accident or spends 10 min
cleaning them up. The rule: diag goes to log files or
/tmp scripts, NOT src/*.py.
3. **Added "No loop, no scope-creep, no report-instead-of-fix"**
to the Critical Anti-Patterns. The 200-line status report
is a confession, not a fix. The 5-phase "future track"
document for a 1-line fix is scope-creep. The "I am not
going to attempt another fix without your direction"
surrender is allowed ONLY if the agent has already
read-predicted-instrumented-run-captured.
4. **Added a new section: "Process Anti-Patterns (Added
2026-06-09)"** with 8 numbered anti-patterns, each with
a Symptom, Rule, and reference. The 8 patterns are the
ones the user explicitly called out: Deduction Loop,
Report-Instead-of-Fix, Scope-Creep Track-Doc,
Inherited-Cruft, Diagnostic Noise in Production, Premature
Surrender, Verbose Commit Message, Isolated-Pass
Verification Fallacy.
These are the rules the user is filtering out of LLM training
data noise. The full ruleset is the source of truth; AGENTS.md
is the load-bearing entry point.
No code modified. Markdown only.
RAGEngine.index_file silently returns when the joined base_dir+file_path
doesn't exist. This caused the RAG batch test to fail with 0 indexed
documents when the live_gui subprocess's active_project_root resolved
to a parent dir (e.g. tests/artifacts/) instead of the workspace
(tests/artifacts/live_gui_workspace/).
The fix: if the primary path doesn't exist, try CWD+file_path. The
base_dir takes priority; CWD is a safety net for relative-path
resolution across the spawn CWD boundary.
This is a defensive fix at the rag_engine layer. It does NOT fix the
underlying path-leakage issue in tests/conftest.py (hardcoded
Path('tests/artifacts/live_gui_workspace')) which needs a proper
fixture refactor. The RAG test still fails in batch due to that
deeper issue, documented in docs/reports/rag_test_batch_failure_status_20260609_pm3.md.
Behavior:
- base_dir+file_path exists: indexed from base_dir (unchanged)
- base_dir+file_path missing, CWD+file_path exists: indexed from CWD (new)
- Both missing: silently returns (unchanged)
Verified: tests/test_rag_index_file_path_fallback.py (3 tests, all pass)
- test_index_file_finds_file_via_cwd_fallback
- test_index_file_uses_base_dir_first
- test_index_file_silently_returns_when_no_match
Note: test file was removed before commit because it was being
abandoned along with the broader path-hygiene refactor. The fix
itself is preserved in src/rag_engine.py.
The venv now has sentence-transformers (installed via uv sync --extra local-rag).
The RAG test passes in isolation (7.10s) but fails in batch with a NEW error:
'RAG context not found in history' (test_rag_phase4_final_verify.py:95).
This is a SEPARATE bug from the missing-dep issue. The RAG test uses
RELATIVE file paths ('final_test_1.txt' instead of absolute). The RAG
engine indexes with these relative paths but the CWD is the project
root, not the test's workspace dir. Result: 0 docs indexed, 0 chunks
retrieved, no '## Retrieved Context' block in history.
The fix to _sync_rag_engine (e62266e8) is still correct - it surfaces
the error when the dep is missing. The dep is now installed, so the
sync/index/AI flow runs to completion. The new failure is a deeper
RAG test infrastructure bug that needs a separate track to fix.
The bug: when the local embedding provider fails to initialize
(e.g. sentence-transformers not installed), RAGEngine.__init__
leaves self.embedding_provider = None (initialized at line 93
but never overwritten by the failing LocalEmbeddingProvider ctor).
The constructor returns. _sync_rag_engine's else branch then
sets status to 'ready' - a lie. The RAG panel shows 'ready'.
The user triggers a retrieval. The engine either has a broken
embedding provider (None) or the retrieval fails silently.
The RAG context never appears in the AI's history.
The fix: in _sync_rag_engine's _task, after RAGEngine(...)
returns, check if engine.embedding_provider is None. If so,
set status to 'error: RAG embedding provider failed to initialize'
and return early. This prevents:
- The engine from being assigned to self.rag_engine
- The rebuild being triggered
- The status being set to 'ready' / 'indexing'
Note: this does NOT make the RAG test pass. The test requires
the sentence-transformers package which isn't installed in this
env. The fix makes the failure reliable (not flaky) and surfaces
the right error message.
TDD: 3 tests added in tests/test_rag_engine_ready_status_bug.py:
- RAGEngine ctor raises ImportError on missing sentence-transformers
- _sync_rag_engine sets status to 'error' (not 'ready') on init failure
- RAGEngine ctor leaves embedding_provider=None when init fails
All 3 pass. The RAG batch test now fails reliably at line 46
with the clear error message.
User asked: is there anything in our workflow or agent markdown
that should be updated or introduced based on this session?
This commit is the AUDIT ONLY. No workflow files are modified.
The 10 recommendations are not yet applied. User picks which to
act on, which to defer, which to discard.
docs/reports/workflow_markdown_audit_20260608.md (~370 lines):
Read all the workflow/agent markdown in scope (AGENTS.md,
CLAUDE.md, GEMINI.md, all 5 .agents/skills/*/SKILL.md, the 4
.agents/agents/*.md, conductor/workflow.md, product.md,
product-guidelines.md, tech-stack.md, index.md, tracks.md,
edit_workflow.md, the 2 existing code_styleguides/*.md, and the
4 .agents/policies/*.toml + 7 .agents/tools/*.json).
Cross-referenced each against the 7 new session artifacts
(nagent_review, 3 docs guides, ASCII-sketch workflow, SSDL
digest, C11 interop v1+v2, 2 new tracks) and the 3
user-correction patterns (duffle-as-style-ref, v2
request/response model, "only under hard constraint").
The 10 recommendations:
1 (HIGH) Update architecture-fallback with new docs
2 (HIGH) Document ASCII-sketch workflow in workflow.md
3 (HIGH) Document SSDL digest in product-guidelines.md
4 (HIGH) Add user_corrections_log to State.toml Template
5 (MED) Document contingency track pattern
6 (MED) Update Compaction Recovery to reference session_synthesis
7 (MED) Document v1->v2 framing iteration anti-pattern
8 (MED) Document preserve-before-compact archive pattern
9 (LOW) Document MiniMax understand_image for ASCII verification
10 (LOW) Document per-proposal commit chain with git notes
4 HIGH-priority = ~75 min to act on. All 10 = ~2-3 hours.
The audit is conservative: it does NOT recommend changing TDD,
the per-task commit discipline, the 4-tier MMA model,
product.md, tech-stack.md, the existing styleguides, or
adding new audit scripts. The session did not surface conflicts
with any of these.
Meta-pattern: workflow/agent markdown is the theoretical
contract; session artifacts are the empirical evidence; when
the two diverge, update the theory to match the evidence.
This session's evidence (new methodology, new vocabulary, new
patterns, new anti-patterns) drives the 10 recommendations.
Foundation document for the future test_infra_hardening track that
will address session-scoped live_gui fixture isolation, silent
__getattr__/__setattr__ contract assumptions, and similar test
infrastructure fragility.
Also documents the test_rag_phase4_final_verify batch failure
that surfaces after the __getattr__ fix unblocks
test_full_live_workflow. The RAG test failure is NOT a regression
- it reproduces on pre-fix HEAD too. It's a pre-existing test
isolation issue (the live_gui fixture is session-scoped, so state
from the 4 sims pollutes the controller).
PR1 follow-up (the actual IM_ASSERT root cause fix).
The IM_ASSERT in 'MainDockSpace' was triggered by the
render_approve_script_modal function (gui_2.py:4895) calling
imgui.checkbox with a None value for app.ui_approve_modal_preview.
The chain of bugs:
1. AppController.__getattr__ returned None for ANY ui_ attribute
(line 1237-1238). This was intended as a safety net for ui_*
flags defined in __init__ but it was too généreux: it returned
None for ui_ attrs that were NEVER set.
2. The pattern in render_approve_script_modal:
if not hasattr(app, 'ui_approve_modal_preview'):
app.ui_approve_modal_preview = False
_, app.ui_approve_modal_preview = imgui.checkbox(..., app.ui_approve_modal_preview)
relied on hasattr() returning False for unset attrs to trigger
the initialization. But the App.__setattr__ checks
hasattr(self.controller, name) to decide where to route
assignments. The controller's __getattr__ returned None for
ui_approve_modal_preview, so hasattr() returned True. The
App.__setattr__ routed the assignment to the controller.
The controller's __getattr__ then returned None on read,
silently dropping the False value.
3. The next line called imgui.checkbox with None, which raised
a TypeError. The TypeError propagated out of
render_approve_script_modal without closing the modal,
leaving the ImGui scope stack unbalanced. The unbalanced
scope triggered IM_ASSERT(Missing End()) on the next frame.
Fix: AppController.__getattr__ now only returns None for an
EXPLICIT allowlist of ui_ attrs that are defined in __init__.
For any other missing attribute (including the case
'hasattr() should return False'), it raises AttributeError.
The App.__getattr__ was also fixed (per the test) to check
hasattr(controller, name) before delegating. This is defense in
depth in case other __getattr__ patterns are added.
Test verification (TDD red → green):
- 1/1 test_app_getattr_hasattr_bug PASSES (verifies hasattr
returns False for unset attrs via App.__getattr__)
- 1/1 test_app_controller_getattr_ui_bug PASSES (verifies hasattr
returns False for unset ui_ attrs on controller)
Live verification:
- 4 sims + test_live_workflow + 2 markdown tests: 7/7 PASS in 83.15s
- Previously failed at 200s+ with 'cannot schedule new futures after
shutdown' / 121s with 'GUI is degraded before test starts'
- Now passes cleanly. The IM_ASSERT no longer fires.
13/13 related unit tests pass (app_controller_* + app_run_* +
app_getattr_*). No regressions in 51/51 io_pool/warmup/sigint/etc.
unit tests.
The SSDL digest (docs/reports/computational_shapes_ssdl_digest_20260608.md,
504 lines, 30KB) is the theoretical foundation for the chunkification
pattern. Per the digest's Technique 5 "Assume-away (Xar)" in §2.2
and the "Xar-style chunked arrays" recommendation in §5.2, the
chunkification track is a *direct application* of the SSDL's
"assume as much as possible" lens (§4).
This commit adds the SSDL digest to the See Also of the v1+v2
C11-Python interop assessment (front-matter Cross-references line).
The same cross-reference is also being added to:
- conductor/tracks/chunkification_optimization_20260608_PLACEHOLDER/spec.md
(in a new §6.1 "SSDL alignment" subsection)
- conductor/tracks/manual_ux_validation_20260608_PLACEHOLDER/spec.md
(in §5 Architectural Reference + §6 See Also + a new §2.6
"SSDL cross-reference" section that distinguishes GUI ASCII
vocabulary from SSDL vocabulary)
No code modified. Cross-reference only.
Also: small update to conductor/tracks.md to add the 2 new
tracks (manual_ux_validation_20260608_PLACEHOLDER as Active;
chunkification_optimization_20260608_PLACEHOLDER as Backlog/Contingency).
The user said (verbatim): "On number 1. I love the idea and definitely
see poitental." This commit creates a full track that promotes the
ASCII-sketch UX ideation workflow
(docs/reports/ascii_sketch_ux_workflow_20260608.md, 340 lines) to
a real track with a concrete first target.
The track complements (does not replace) the existing
manual_ux_validation_20260302 track (which is a general UX review
track; this 2026-06-08 track is *focused* on the ASCII-sketch
workflow specifically).
Files (5 total, ~52KB, 12,000+ words):
- spec.md (186 lines, 9 sections) - track design, 5 open
questions, first target analysis, SSDL cross-reference
- plan.md (~280 lines, 4 phases, 21 tasks) - TDD-style with
WHERE/WHAT/HOW/SAFETY annotations
- metadata.json (~120 lines) - structured metadata, 5 open
questions with defaults, 5 SSDL principles available
- state.toml (~95 lines) - per-task tracking + phase status
- index.md (~50 lines) - track context + related docs
Key design decisions captured:
1. Two distinct vocabularies are conflated at first glance:
- GUI ASCII (the workflow) for panel sketches
- SSDL (computational shapes digest) for internal code sketches
Spec §2.6 makes the distinction explicit; both are useful for
this track (GUI ASCII for Phase 2 design; SSDL for Phase 3
internal refactoring documentation).
2. The 5 open questions from the workflow report (Q1 vocabulary,
Q2 comparison policy, Q3 storage location, Q4 tooling,
Q5 frequency) are documented with sensible defaults in
spec.md §2.1-2.5 and metadata.json. The user can override
any of them; defaults pre-stage the work.
3. First target is src/gui_2.py:3770 render_discussion_entry
(Discussion Hub per-entry panel). Rationale:
- Most-edited surface (every AI/user message)
- User has strong opinions (per nagent_review_20260608 3 rounds
of corrections)
- 23-op matrix A1-A7 is the source of truth
- ImGui layout maps cleanly to ASCII
- SSDL defusing techniques can guide the internal refactoring
4. 4 phases: 1=resolve 5 questions, 2=execute workflow on first
target (1-3 ASCII rounds), 3=implement per design contract
(TDD with 7 test files for A1-A7 operations),
4=document the pattern + propose 5-7 next targets.
Cross-references added throughout:

for a different purpose" note in spec §2.6)

No code modified. Track is active; Phase 1 (5 user-questions) is
the current phase. User-confirmed worth doing in the prior turn.
The user's third correction this session changed the framing
from "build a stateful C extension" to "wait for a hard constraint,
then build a request/response blob pipeline." This commit creates
a 1-page contingency document (no plan.md, no implementation)
that captures:
- The threshold: "only worth it under a hard constraint that
no existing Python package can solve"
- The shape when activated: subprocess-launch C11 binary with
request/response blob wire format (NOT stateful CPython C
extension)
- The 2 cited candidates (markdown parsing into aggregate markdown,
context snapshot processing) are NOT currently bottlenecks per
src/aggregate.py:380-454 (pure-Python string concat, zero
third-party markdown deps in pyproject.toml:6-27) and
src/history.py:1-141 (bounded ~500KB at 100-snapshot capacity,
debounced)
- The SSDL digest's Technique 5 "Assume-away (Xar)" in §2.2 +
"Xar-style chunked arrays" recommendation in §5.2 pre-support
this track

assessment; explicitly cited in spec's §6 See Also)
No code modified. Track does NOT appear in the active queue
of conductor/tracks.md; appears in the Backlog / Contingency
section as a reference, not a commitment.
Activation criteria (per metadata.json):
1. Profiling shows a real bottleneck in a target code path
2. The bottleneck cannot be solved with existing Python packages
3. The user explicitly approves activation
Without all 3, this track stays deferred. Default action is don't.
The user pushed back on the v1 recommendation (commit 68354841) twice
in this turn. Both corrections reshape the answer.
Correction 1 (already incorporated): duffle.h + pikuma ps1 are a
C11 STYLE REFERENCE, not an interop pattern. (Captured in v1 §0.)
Correction 2 (NEW, this commit): The C11 path is only worth it under
a hard constraint that no existing Python package can solve. The
shape is request-blob -> C11 pipeline -> response-blob, NOT a
stateful C extension with a Python-facing API. Targets cited:
parsing markdown files/sources into aggregate markdown, context
snapshot processing, "possibly other things."
This commit adds Part 3 (sections 3.1-3.12) to the existing doc.
Part 1 (style) and Part 2 (general interop) stay as background.
Section 4 is re-flagged as "SUPERSEDED - see Part 3".
Part 3 covers:
- The two moves the user's second correction made (threshold-shift
on when, shape-change on what)
- Grounded analysis of the 2 cited targets against actual code:
* src/aggregate.py:380-454 (current markdown hot path is
pure-Python string concat; pyproject.toml has zero
third-party markdown deps)
* src/history.py:1-141 (snapshot processing is bounded
~500KB at 100-snapshot capacity; pickle is the obvious
cheap fix, not C11)
- The request/response wire format design space (text vs binary
vs hybrid envelope-text+payload-binary)
- The pipeline API shape (single C entry point, subprocess-launch
model)
- Revised answer to the "chunkification" question (chunk-array
becomes an internal C implementation detail, not a Python
type)
- Decision tree: profile first, try existing Python packages,
only reach for C11 when hard constraint surfaces
- The 4 questions to revisit when constraint surfaces
- Revised insight: v2 (subprocess + wire format) is strictly
more tractable than v1 (stateful C extension)
- Track implications: chunkification_optimization becomes a
1-page contingency, not a full track; manual_ux_validation
unaffected and confirmed
- v2 verdict matrix (11 rows) replacing v1's 7
Cross-references the actual code paths I read this turn:
- src/aggregate.py:380-454 (build_markdown_from_items)
- src/summarize.py:1-219 (the 3 _summarise_* functions)
- src/history.py:1-141 (UISnapshot, HistoryManager)
- pyproject.toml:6-27 (no markdown deps)
The user is right to push back. The v1 framing was over-engineered.
"Build a stateful C extension" assumed a future need; the actual
answer is "wait for a real bottleneck, then build a simple
subprocess pipeline." The 843-line doc now captures both the
v1 over-engineering AND the v2 contingency plan, so future
sessions can see the iteration and learn from it.
The user asked a sharp, skeptical question: can a chunk-based C11
data structure actually interop with Python's runtime in a way
that's useful for Manual Slop? They explicitly corrected my
first-draft framing (the duffle.h + pikuma ps1 files are a C11
*style reference*, not an interop pattern). The assessment
investigates honestly and reports tractable-vs-not.
docs/reports/c11_python_interop_assessment_20260608.md (564 lines, 38KB):
Part 1: C11 style reference summary
- 11 style observations from reading duffle.h + main.c + pikuma
ps1 duffle/ + hello_gte.c end-to-end
- Byte-width typedef convention (U1/U2/U4/U8, S1/S2/S4/S8, B1-B8, F4/F8)
- The macro meta-DSL (Struct_/Enum_/Array_/Slice_/Opt_/Ret_)
- The I_/IA_/N_ inline discipline
- The r/v pointer rule (restrict OR volatile, never both, never const)
- Slice + Slice_T as the data-structure primitive
- FArena as the allocation primitive (single-buffer, NOT chunked)
- defer/defer_rewind/scope as the cleanup primitive
- KTL (linear key-value table) as the "assume small N" pattern
- What a chunk-array in duffle.h style would look like
Part 2: Interop design space (the actual question)
- 5 candidate interop layers: ctypes, cffi, pybind11, custom
CPython C extension, NumPy wrap
- Honest assessment matrix: build cost, per-op overhead, style
fit, lego-set pattern support
- Verdict: custom CPython C extension is most tractable; pybind11
is style-mismatched; ctypes/cffi work for non-hot-path
- What "MVP chunked C11 package" requires (~500-1000 LOC total)
- 5 questions to ask the user before this becomes a track
- Crucial insight: the user's "unorthodox" interop is most likely
duffle.h-style C11 + thin PyTypeObject glue at the bottom of
the same .h file. Tractable, style-fit high.

(manual_ux_validation_20260608_PLACEHOLDER + chunkification_optimization_20260608_PLACEHOLDER).
The user's question resolved the "skeptical of #2" concern by
scoping the tractable path: CPython C extension in duffle.h style.
The "lego-set of user-defined Python->C11 chunk ops" is NOT
tractable without a Python->C11 AST emitter, which is a
different (much larger) track.
The user explicitly requested the biggest in-depth report I can
muster at 478,992 tokens (94% of context window). The next
session will start with a fresh context; these two documents are
the minimum-sufficient anchor.
docs/reports/session_synthesis_20260608.md (579 lines, 40KB):
- 12 sections covering every artifact this session produced
- The 5 sources loaded: 2 YouTube transcripts + 2 Fleury
articles + user's chunk-ideation archive
- The 10 commits in the session's commit chain (with the
user's test-fragility work adjacent but not mine)
- The 4 audit-time heuristics derived from the 5-source lens
- The "what the user should know" section for next session
docs/reports/proposed_new_tracks_20260608.md (190 lines, 12KB):
- 2 new tracks proposed (manual_ux_validation_20260608_PLACEHOLDER,
chunkification_optimization_20260608_PLACEHOLDER) with
spec-ready detail
- 8 non-recommendations (so the user knows what I'm NOT
suggesting)
- A "what I'd recommend" section with one-tracks-when
sequencing
No code modified. Both are session-final artifacts, not tracks.
They live in docs/reports/ alongside the other session outputs
(SSDL digest, ASCII-sketch workflow, chunk ideation archive).
Cross-references the 5 sources (all committed to docs/transcripts/
and docs/ideation/ in earlier user commits):

- docs/reports/computational_shapes_ssdl_digest_20260608.md
- docs/reports/ascii_sketch_ux_workflow_20260608.md
These 5 documents are the session's "thinking-aid" corpus. The
synthesis is the *index*; together they're the minimum-sufficient
context to re-anchor any future session.
The user specified that the code_path_audit_20260607 track should run
AFTER the 4 foundational tracks complete (qwen_llama_grok,
data_oriented_error_handling, data_structure_strengthening,
mcp_architecture_refactor). This commit formalizes that timing
and grounds the audit's analytical framing in the 5 sources loaded
into context on 2026-06-08.
3 surgical additions to the spec/plan, no task changes:
1. Post-4-tracks timing (new section in spec.md §"Timing", plus
a "Timing" callout in plan.md's opening):
- The 4 tracks will significantly reshape src/ai_client.py,
src/mcp_client.py, src/app_controller.py, and
src/type_aliases.py
- Running the audit on pre-refactor code would produce a
report that's stale on day 1
- The post-4-tracks timing ensures the audit grounds
optimization decisions for the *resulting* architecture
- Pre-flight check: verify all 4 tracks are [x] completed
in conductor/tracks.md before starting this track
2. Analytical framing (new section in spec.md §"Analytical Framing
(5-source lens)"):
- Maps each of the 5 sources (Fleury taxonomy + Fleury
combinatoric + Muratori Big OOPs + Reece Assuming + user's
chunk ideation) to specific audit-time heuristics
- 4 concrete heuristics: effective-codepath count,
entity-hierarchy fingerprint, assumed-too-much detector,
chunkification candidates
- The heuristics shape REPORT INTERPRETATION, not the
static cost model (which stays data-grounded in
EXPENSIVE_THRESHOLD + per-class weights)
3. See Also cross-references in spec.md (6 new entries):

digest that synthesizes the 4-source computational-shapes
thinking; the audit's tree/mermaid outputs ARE
computational-shape visualizations)
4. tracks.md entry updated to include the spec/plan links and
a brief status note that the audit is post-4-tracks.
5. plan.md has a "Timing" callout at the top stating the 4
tracks must ship before the plan executes.
No code modified. The audit's tasks (Phases 1-6) are unchanged
in structure; the new sections only add analytical context
and timing constraints.
PR3 of the test_full_live_workflow_imgui_assert fix sequence.
When a prior live_gui test in the same session crashes the GUI (e.g.
via an ImGui IM_ASSERT from cumulative panel state), the controller's
_io_pool gets shut down. The next test starts in a degraded state
but only discovers this 120s later when its project switch times
out with a confusing 'cannot schedule new futures after shutdown'
error.
This commit adds a /api/gui_health pre-flight check at the start of
test_full_live_workflow. If the GUI is degraded, the test fails
fast (within 1s) with a clear, actionable message that includes:
- The exact RuntimeError that caused the degradation
- The full traceback of the last ImGui scope mismatch
- A note that the new test cannot proceed with a dirty state
Per user feedback 2026-06-08: 'I don't want a batch to be too fragile
where I can't restart the app and continue with the next test file
if it fails. Just has to note that the new file didn't get to deal
with a dirty state.'
Also includes the planning documents written earlier in this session:
- TODO_test_full_live_workflow_v2.md (task list)
- test_full_live_workflow_imgui_assert_20260608.md (root cause report)
- test_full_live_workflow_propagation_digest_20260608.md (solutions digest)
- batch_resilience_plan_20260608.md (batch resilience plan)
Verification:
- test_full_live_workflow in isolation: 13.45s PASS (health=True, no degrade)
- 4 sims + test_full_live_workflow in batch: 76.46s (1 FAIL fast, 4 sims PASS)
- Without PR3 fix: 200s FAIL with confusing 120s timeout
- With PR3 fix: 76s FAIL with clear 'GUI is degraded' message
- The fast-fail is observable, not silent (per user's 'wrap might be
worth it if that properly lets us handle the assert')
4 surgical additions to the spec, no task changes:
1. list_tool_schemas on the SubMCP Protocol: Added the method
to §3.1 (The SubMCP Protocol). Per nagent_review Pitfall #6
(hard-coded tool discovery) and takeaway #5 (self-describing
tools), each sub-MCP advertises its own capabilities via
list_tool_schemas() rather than relying on a central registry.
This is the equivalent of nagent's collect_bin_tool_descriptions
per sub-MCP. The MCPController.get_tool_schemas() becomes a
simple aggregator.
2. Security model is the contract: Added a new Important note
to §3.3 (The 3-Layer Security Model). The 3 layers
(Allowlist Construction -> Path Validation -> Resolution
Gate, per docs/guide_mcp_client.md) are not just refactored
- they are the CONTRACT between MCPController and the
sub-MCPs. Sub-MCPs receive a pre-validated Path and trust
it. They do NOT re-validate. The refactor is structural,
not security-changing.
3. Docs touchpoint in Phase 7: Added the docs touchpoint to
Phase 7 per the docs Refresh Protocol. The update to
docs/guide_mcp_client.md should add a Sub-MCP Architecture
section, link the list_tool_schemas pattern to 3-Layer
Security Model, and cross-link the 3 new guides from
the 2026-06-08 docs refresh.
4. See Also cross-references: Added 8 new entries to §12.2:
- docs/guide_context_aggregation.md (FileItem consumer)
- docs/guide_state_lifecycle.md (App state delegation)
- docs/guide_discussions.md (23-operation matrix)
- conductor/tracks/qwen_llama_grok_integration_20260606/
(Result return type coordination)
- conductor/tracks/nagent_review_20260608/{report,takeaways}.md
- (2 specific data_oriented_error_handling and
data_structure_strengthening cross-refs)
No plan.md changes.
4 surgical additions to the spec, no task changes:
1. ProviderHistoryMessage: Added a new alias to §3.1 (The
Aliases). Per nagent_review Pitfall #4 (provider history
divergence), the UI/curation layer (HistoryMessage, edited
via disc_entries[i].content) and the SDK layer
(ProviderHistoryMessage, the bytes actually replayed to the
LLM) are *distinct*. Conflating them via a single alias
perpetuates the bug. The new alias is documented as a
separate concept with its own use sites (_anthropic_history,
_deepseek_history, _minimax_history, _grok_history,
_llama_history). The follow-up public_api_migration_20260606
track is the natural moment to unify the two layers; this
spec just makes the distinction explicit.
2. FileItem alias points to the existing models.FileItem
dataclass, not Metadata. Per docs/guide_context_aggregation.md
(added 2026-06-08), FileItem is a 9-field dataclass
(path, auto_aggregate, force_full, view_mode, selected,
ast_signatures, ast_definitions, ast_mask, custom_slices,
injected_at) with a __post_init__ normalizer. Aliasing it to
dict[str, Any] would lose the type safety. The 9 other
aliases remain dict aliases for round-trip compatibility.
3. gui_2.py and mcp_client.py as follow-up: Added a Note
(dated 2026-06-08) to the Out of Scope section. The 23
lower-impact files (deferred) are dominated by gui_2.py
(26+ weak sites per guide_state_lifecycle.md) and
mcp_client.py (will be touched heavily by the parallel
mcp_architecture_refactor_20260606). The deferral is correct
but the follow-up should explicitly call out these two
files as the next targets, rather than implying they're
handled.
4. See Also cross-references: Added 7 new entries to §12.2:
- docs/guide_models.md (FileItem dataclass source)
- docs/guide_context_aggregation.md (FileItems consumer)
- docs/guide_discussions.md (HistoryMessage shape)
- docs/guide_state_lifecycle.md (state delegation)
- conductor/tracks/mcp_architecture_refactor_20260606/
- conductor/tracks/nagent_review_20260608/{report,takeaways}.md
No plan.md changes.
PR2 of the test_full_live_workflow_imgui_assert fix sequence.
When an ImGui scope mismatch (IM_ASSERT(Missing End())) fires in
immapp.run (e.g. after cumulative state corruption from prior sims'
panel renders), the RuntimeError propagates out of app.run(). The
controller's _io_pool gets shut down via __del__/finalization. The
hook server (separate ThreadingHTTPServer) survives. Subsequent test
clicks fail with 'cannot schedule new futures after shutdown' and
the test times out after 120s with no clear signal of what went
wrong.
This commit:
1. Wraps immapp.run in try/except RuntimeError in gui_2.py:618.
On assertion: logs the error to stderr (NOT silent), records
it on controller._gui_degraded_reason and _last_imgui_assert,
and returns from run() so the hook server keeps serving.
2. Adds _gui_degraded_reason and _last_imgui_assert to
AppController.__init__ (initialized to None).
3. Adds /api/gui_health endpoint in api_hooks.py:148. Returns
{healthy, degraded_reason, last_assert, io_pool_alive}.
4. Adds ApiHookClient.get_gui_health() with the matching unit
tests (3 mocked tests + 1 live test).
Per user feedback 2026-06-08:
- The wrap does NOT silently swallow the error. It logs at ERROR
level and surfaces it via the health endpoint.
- Tests can call client.get_gui_health() to detect a degraded GUI
and fail fast with a clear message.
TDD: tests written first, confirmed to fail, then fix applied.
34/34 unit tests pass. 1/1 live test passes (live_gui health
endpoint reports healthy=True on fresh subprocess).
3 surgical additions to the spec, no task changes:
1. New ErrorKind: Added PROVIDER_HISTORY_DIVERGED_FROM_UI to
the ErrorKind enum. Per nagent_review Pitfall #4 (provider
history divergence: user edits disc_entries[i].content via
the discussion UI but ai_client._<provider>_history still
replays the original). The new kind makes the divergence
*detectable* and *reportable* so the follow-up
public_api_migration_20260606 track can collapse the two
history layers. The Result pattern from this track is the
natural carrier for the signal.
2. State-delegation regression tests: Added mandatory
regression tests to the testing strategy in §6 for the
ai_client refactor (highest-risk phase). The new tests
exercise:
- app.temperature = 0.5 round-trips through App.__getattr__/
__setattr__ delegation (per gui_2.py:666-675)
- controller.disc_entries[i].content is reflected in the
next send_result()'s messages parameter
- The 3 per-provider history locks serialize correctly under
concurrent send_result() calls
The reason this is mandatory: per guide_state_lifecycle.md
(added 2026-06-08), the App.__getattr__/__setattr__ pattern
means a partial refactor manifests as silent AttributeError
deep in test code, not at the refactor commit boundary.
3. See Also cross-references: Added 6 new entries to §12.3:
- docs/guide_ai_client.md (per-provider history globals)
- docs/guide_mcp_client.md (3-layer security model)
- docs/guide_state_lifecycle.md (3 per-thread + 7-lock pattern)
- docs/guide_discussions.md (23-operation matrix)
- docs/guide_context_aggregation.md (build_discussion_section)
- conductor/tracks/mcp_architecture_refactor_20260606/
- conductor/tracks/nagent_review_20260608/{report,takeaways}.md
No plan.md changes. Plan tasks are task-level and will flow from
the spec changes when the track is re-planned.
4 surgical additions to the spec, no task changes:
1. Result return type: Added a coordination note in §3.1 (Data-
Oriented Design) explaining that the shared send_openai_compatible
helper should return Result[NormalizedResponse, ErrorInfo] from
day 1, not NormalizedResponse + ProviderError raise. This is so
the downstream data_oriented_error_handling_20260606 track is
a small mechanical pass over new code, not a second migration.
References nagent_review Pitfall #4 (provider history divergence)
and the ErrorKind.PROVIDER_HISTORY_DIVERGED_FROM_UI use case.
2. Declarative read, not behavioral dispatch: Added clarification
to §6 (UX Adaptation) that the capability matrix is a *read* of
declarative data, not a new dispatch layer. Per nagent_review
Pitfall #1 (opaque function calling in the Application is the
correct choice; nagent-style protocol is for Meta-Tooling),
UI elements are visible/enabled/disabled/hidden but the
*behavior* they invoke is unchanged. Three concrete examples
added: screenshot button, cost panel, cache panel.
3. PROVIDERS source of truth: Added a NOTE in §3.2 (Module Layout)
that src/models.py:79-86 PROVIDERS is the existing single
source of truth for the (vendor, model) enumeration. The
capability registry reads from this constant rather than
introducing a parallel list. Cross-references
docs/guide_models.md.
4. Docs touchpoint: Expanded Phase 6 (Docs + Archive) in §9 to
note that docs/guide_ai_client.md needs the new providers +
the shared helper documented, and that
docs/guide_context_aggregation.md (added 2026-06-08) is the
reference for the aggregate.py pipeline that all new providers
use.
5. See Also cross-references: Added 3 new entries to §13.2:
- docs/guide_context_aggregation.md (the new pipeline guide)
- conductor/tracks/nagent_review_20260608/report.md (§1, §5, §15)
- conductor/tracks/nagent_review_20260608/nagent_takeaways_20260608.md
(§1, §2, §9)
No plan.md changes. Plan tasks are task-level and will flow from
the spec changes when the track is re-planned.
Gitea (and any case-sensitive filesystem) was rendering the [Top]
nav links in /docs as broken because of two bugs:
1. Case-sensitivity: 22 links used '../README.md' (all-uppercase)
but the actual file is 'docs/Readme.md' (capital R, lowercase
rest). 21 guide_*.md nav bars were affected, plus 1 internal
cross-link in Readme.md itself. Works on Windows (case-
insensitive) but broken on Linux/Gitea.
Fix: 22 occurrences across 22 files changed
'../README.md' -> '../Readme.md'
2. Wrong relative-path level: 16 links used '../../conductor/...'
from 'docs/guide_*.md' to reach 'conductor/'. This goes up 2
levels to 'projects/', which doesn't exist. The correct path
from 'docs/guide_*.md' to 'conductor/' is 1 level up
('../conductor/...'). 12 unique patterns across 10 files
affected.
Fix: 16 occurrences across 10 files changed
'../../conductor/' -> '../conductor/'
3. Bonus: 1 planned-guide link in guide_context_curation.md
referenced a never-written 'guide_context_presets.md'. The
ContextPreset schema is now fully covered in the new
'guide_context_aggregation.md' (per the 2026-06-08 docs
refresh). Fix: link target updated.
No content was changed, only link paths. 24 files, 37 link
replacements, 37 deletions.
Verification:
- All .md links in docs/ now resolve to existing files
(validated by path-resolution check from each file's directory)
- The 3 new guides from the previous docs refresh commit
(guide_discussions.md, guide_state_lifecycle.md,
guide_context_aggregation.md) had the case bug inherited from
guide_architecture.md's existing nav pattern; their top-of-file
nav bars are now correct
- The 21 pre-existing guide nav bars that had the same bug
(all 21 of them, except the 3 that used the correct case:
guide_mma.md, guide_simulations.md, guide_tools.md) are now
also fixed
- Inter-guide links (e.g. [Discussions](guide_discussions.md))
were not affected; they were always correct because both the
link text and the actual filename are lowercase
This is a docs-only fix. No code modified.
Per the docs Refresh Protocol (conductor/workflow.md), after a
reference/analysis track ships, the affected guides must be updated
to reflect new module structure or new conventions. The nagent_review
track (9cc51ca9) produced a deep-dive + 10 actionable takeaways that
named 3 documentation gaps in /docs. This commit fills them.
3 new guides (1,122 lines total):
1. guide_discussions.md (353 lines) — The Discussion system
- 23-operation matrix: A1-A7 per-entry + B1-B11 discussion-level
+ C1-C5 undo/redo
- Take naming convention (<base>_take_<n>), branching, promotion
- User-managed role list (app.disc_roles)
- Per-role filter linked to MMA persona focus
- _disc_entries_lock thread-safety contract
- Hook API session endpoints
- Persistence: _flush_to_project, _flush_disc_entries_to_project,
context_snapshot
- 9 file:line refs into gui_2.py:3770-4260 + history.py
2. guide_state_lifecycle.md (375 lines) — Undo/redo + reset + state
delegation
- HistoryManager + UISnapshot (13 captured fields, 100-snapshot
capacity, debounced change-detection at render frame)
- _handle_reset_session (clears 30+ fields, replaces project,
preserves active_project_path per the 2026-06-08 regression fix)
- App.__getattr__/__setattr__ state delegation to Controller
- 4-thread access pattern with 7 lock-protected regions
- State persistence: in-memory vs project TOML vs config TOML
- Hot-reload integration
- Hook API registries (_predefined_callbacks, _gettable_fields)
- 14 file:line refs into gui_2.py:1140-1170, history.py,
app_controller.py:3286-3356
3. guide_context_aggregation.md (394 lines) — The aggregate.py
pipeline
- 3 aggregation strategies (auto, summarize, full)
- 7 per-file view modes (full, summary, skeleton, outline,
masked, custom, none)
- Full FileItem schema (9 fields + __post_init__ normalizer)
at models.py:510-559
- ContextPreset schema and ContextPresetManager
- Tier 3 worker variant (build_tier3_context with FuzzyAnchor
re-resolution and focus-file handling)
- force_full / auto_aggregate short-circuits
- Cache strategy (static prefix + dynamic history)
- 23 file:line refs into aggregate.py:36-518 + models.py:909-937
8 existing guides cross-linked to the 3 new guides and to the
nagent_review track:
- guide_gui_2.md (+ See Also entries for discussions,
state lifecycle, context aggregation,
nagent_review report)
- guide_app_controller.md (+ See Also entries for discussions,
state lifecycle, context aggregation,
nagent_review report)
- guide_context_curation.md (+ new See Also section pointing to
context aggregation + nagent_review)
- guide_architecture.md (+ new See Also section listing all 10
guides + nagent_review report)
- guide_ai_client.md (+ See Also entries for state lifecycle,
context aggregation, nagent_review
pitfalls #2 and #4)
- guide_mma.md (+ new See Also section pointing to
context aggregation, discussions,
nagent_review report §9 + takeaways §3/§10
for SubConversationRunner priority)
- guide_models.md (+ See Also entries for context
aggregation, discussions, nagent_review
report §6 on FileItem as strongest
curation dimension)
- Readme.md (+ 3 new guide entries in the index
table, with one-line summaries)
No code modified. This is documentation only.
Why these 3 guides specifically:
- guide_discussions.md: The discussion system is the user's most
edited surface. nagent_review's report §3 enumerated 23 operations
(A1-C5) that previously existed only as scattered file:line refs
across gui_2.py. A dedicated guide makes the operation matrix
discoverable.
- guide_state_lifecycle.md: The undo/redo + reset + state delegation
machinery is architecturally load-bearing but scattered across 4
files. After nagent_review identified the provider-side history
divergence as Pitfall #4, the relationship between Manual Slop's
state and the provider's state needs explicit documentation.
- guide_context_aggregation.md: aggregate.py (518 lines) is the
most-touched module after ai_client.py but had no dedicated
guide. nagent_review confirmed it's Manual Slop's strongest
curation dimension. A dedicated guide makes the 7 view modes
and 3 strategies discoverable.
The 3 new guides total 1,122 lines and follow the existing
per-source-file deep-dive style (architectural, data-oriented,
state-management-focused).
Reference/analysis track. Produces 0 code changes.
Artifacts (conductor/tracks/nagent_review_20260608/):
- spec.md (240 lines) - track wrapper with Application/Meta-Tooling framing
- report.md (571 lines) - 14-section deep-dive; primary deliverable
- comparison_table.md (79 lines) - flat side-by-side reference
- decisions.md (286 lines) - 10 future-track candidates with priority matrix
- nagent_takeaways_20260608.md (363 lines) - 10 actionable patterns grounded
in code (file:line refs into nagent source and Manual Slop source)
- metadata.json (132 lines) - structured metadata + verification criteria
- state.toml (113 lines) - per-task tracking + user-corrections log (7 entries)
14 nagent principles covered in report.md (durable work, text-in/text-out,
editable state, visible protocol, the loop, per-file memory, repo history,
neighborhoods, sub-conversations, controlled writes, large files, tool
discovery, framework differences, build your own).
6 pitfalls (revised from 8 after user-corrections):
1. No structured output protocol in Application AI (opaque function calling)
2. Provider-specific history in process globals (ai_client._anthropic_history
+ _deepseek_history + _minimax_history)
3. RAG is not 'history as data' (fuzzy, not auditable)
4. AI client is a stateful singleton (2,685-line ai_client.py)
5. No non-MMA disposable sub-conversations (1:1 gap; user-flagged want)
6. Hard-coded tool discovery (45-tool if/elif in mcp_client.py)
User-corrections applied (3 rounds, 7 total corrections recorded):
- Editable discussions: PARTIAL -> PARITY (DIFFERENT FOCUS) with full A1-A7
per-entry + B1-B11 discussion-level + C1-C5 undo/redo operation matrix
- Per-file memory: DOMAIN MISMATCH -> MANUAL SLOP IS STRONGER IN
CURATION DIMENSION (FileItem + ContextPreset vs nagent's inode-keyed
conversation log; complementary, not equivalent)
- Sub-conversations: MMA has it; 1:1 does not -> 'PARITY for MMA; GAP for
1:1 discussions' (user wants this)
- RAG: opt-in, not gap; user wants pre-staging via sub-conversation
- Personas: config bundling (can opt out via AI settings)
- Tool discovery: deferred (user has 'intent based DSL' idea but 'no where
near that ideation yet')
10 actionable takeaways (separate from the 6 pitfalls - those are
diagnosis, these are prescription):
1. State visibility (UI inspector for in-process state)
2. Readable conversation log (text-greppable, not just JSON-L)
3. Sub-agents for 1:1 (HIGH priority - user-flagged)
4. File-identity over file-path (st_dev:st_ino rename-safe)
5. One loop shape visible in diagnostics
6. Visible retry on protocol failure
7. Meta-Tooling DSL (intent-based, deferred)
8. Self-describing tools (subsumed by mcp_architecture_refactor_20260606)
9. Single source of truth for disc_entries + provider history
10. Sub-agent return type constraint (bake into candidate #1 spec)
Domain classification: every recommendation tagged Application / Meta-Tooling
/ Both per docs/guide_meta_boundary.md. nagent lives in the Meta-Tooling
domain; Manual Slop's Application AI is a different kind of thing.
No code modified by this track (reference/analysis only). All 7 files
parse cleanly (JSON, TOML, Markdown). All internal cross-links resolve.
Track is 'active' awaiting human review; future-track candidates live in
decisions.md and nagent_takeaways_20260608.md.
The 30s wait_for_project_switch timeout was an excessive constraint.
In batch context, prior sims' AI discussion turn workers saturate the
8-worker io_pool, queueing this switch for tens of seconds. The other
defensive waits in the test (warmup 60s, prior switch 60s) already use
60s+, so 30s was the inconsistent outlier.
User confirmed: 'I think not completing in 30s is an excessive constraint
if thats whats going on.'
Verification:
- test_full_live_workflow isolation: 11.69s PASS
- 7-test batch (test_full_live_workflow + 4 extended sims + 2 markdown): 85.83s PASS
Root cause: test_full_live_workflow in batch context (with prior sims
running AI discussion turns) would queue its _do_project_switch behind
the auto-pruner's scan of tests/logs/ (154MB, 6519 files). The 4-worker
pool was saturated, so the switch would never run within 30s.
Fix: bump IO_POOL_MAX_WORKERS from 4 to 8. This gives the pool enough
capacity to run: 2 pruners + the project switch + 5 spare.
Also: add /api/io_pool_status endpoint + get_io_pool_status +
wait_io_pool_idle helpers (kept in api_hooks.py and api_hook_client.py
for the test_api_hook_client_io_pool.py tests, even though the test
itself no longer uses them - they remain useful for future tests that
want to assert pool state directly).
Also: add wait_for_warmup at the start of test_full_live_workflow to
ensure SDK modules are loaded before AI ops.
Test verification:
- test_full_live_workflow in isolation: 11.83s PASS
- test_full_live_workflow in batch (with 4 prior sims): 83.46s PASS
- 30/30 related unit tests PASS
When a prior test in the tier-3-live_gui batch leaves a _do_project_switch
background thread running, the next test's btn_project_new_automated click
sees _project_switch_in_progress=True (from the prior thread) and queues
the new path via _project_switch_pending_path. The queued switch is never
actually submitted to the io_pool, so is_project_stale() stays True and
AI ops (_handle_generate_send) bail with 'project switch in progress;
AI ops disabled'.
Fix: _handle_reset_session now also clears _project_switch_in_progress,
_project_switch_pending_path, and _project_switch_error (under the
existing _project_switch_lock). This way, even if the prior background
thread is still running, the controller reports an idle state and the
new switch can be submitted normally.
Also:
- src/api_hook_client.py: reverted wait_for_project_switch to require
in_progress=False (was relaxed to return on queued path, which misled
the caller into thinking the switch was done)
- tests/test_handle_reset_session_clears_project.py: new test
test_handle_reset_session_clears_project_switch_state asserts
is_project_stale() returns False after reset
- tests/test_api_hook_client_wait_for_project_switch.py: updated
test_wait_for_project_switch_does_not_return_on_queued (in_progress
+ matching path should keep waiting, not return early)
- tests/test_live_workflow.py: added pre-wait for any in-flight switch
before doing btn_reset (so the test waits up to 60s for the prior
switch to complete if needed)
- conductor/todos/TODO_test_full_live_workflow.md: updated Task 4 with
the deeper hang analysis and recommended fix
Known follow-up: test_full_live_workflow still hangs in tier-3 batch
even with this fix, because the new _do_project_switch itself is hung
in the io_pool (likely saturation from prior sims' AI discussion turn
workers). Deeper investigation required.
Following the conductor convention of organizing track-related
artifacts under conductor/. The TODO tracks the test_full_live_workflow
race condition fix and its follow-up items (Tasks 3, 7 still pending;
known batch hang documented).
Tasks 1, 2 (with regression fix), 4, 5, 6 are SHIPPED in prior commits.
Silences the PytestUnknownMarkWarning emitted by test_visual_mma.py and
test_visual_sim_gui_ux.py (3 instances). The @pytest.mark.live mark
already exists in the test files; pyproject.toml just didn't know
about it.
- pyproject.toml: added 'live: marks tests as live visualization tests
(not in CI by default)' to [tool.pytest.ini_options].markers
Replaces the 10x1s blind poll of derived state with a condition-based
wait on /api/project_switch_status. Also adds a defensive file existence
check that fails fast (within 5s) if the click was dropped or the
project creation handler crashed.
The new wait surfaces a clear error message ('Project switch did not
complete in 30s. Last status: ...') instead of the generic 'Project
failed to activate', and exposes _project_switch_error if the controller
reported one.
- tests/test_live_workflow.py: replaced poll loop (lines 57-65) with
wait_for_project_switch + os.path.exists defensive check
