BRIEFING — 2026-09-05T10:30:48Z
Mission
Investigate system architecture, workspace structure, Python environment, PyInstaller packaging constraints, SQLite persistence, and build automation to formulate concrete recommendations for the standalone Windows .exe HAD Digital MVP.
🔒 My Identity
- Archetype: explorer
- Roles: explorer_survey_2
- Working directory: c:\AI Projects\Kais Project\.agents\explorer_survey_2
- Original parent: 8c700e5d-87a4-4452-ab59-6fc2e8946b0d
- Milestone: MVP Architecture & Packaging Survey
🔒 Key Constraints
- Read-only investigation — do NOT implement production source code
- Files for content delivery (reports, handoffs), messages for coordination
- Handoff report strictly follows 5 components: Observation, Logic Chain, Caveats, Conclusion, Verification Method
- Standalone Windows .exe requirement with zero host dependencies
- Embedded SQLite persistence separate from ephemeral _MEIPASS bundle

Investigation State
- Explored paths:
ORIGINAL_REQUEST.md,DISPATCH.md,MVP/,01_System/,03_Architecture/,04_Build/,05_Test/,00_Governance framework/,MVP_PLAN.md,MVP_EXECUTION_PLAN.md
- Key findings:
- Complete pure-Python prototype exists in
MVP/usinghttp.server.BaseHTTPRequestHandlerand SQLite WAL. - Fatal PyInstaller
_MEIPASSdata-loss risk identified:config_manager.pyplaces SQLite database inside ephemeral temp directory unless decoupled into persistent storage. - UI login defect found in
static/app.jsline 81: checksdata.okwhileapp.pyreturns{"message": "Login successful", "user": ...}, displaying "Login failed" on valid logins. - Demo credentials in
app.jsdo not matchseed_demo.pyaccounts. - Report submission payload structure mismatch between
app.js(multi-symptom dict) andapp.py(single symptom fields). - PyInstaller spec was
--onedir, not single-file--onefile.
- Unexplored areas: None. Complete survey achieved.
Key Decisions Made
- Recommended Python standard library
ThreadingHTTPServerover Flask: zero host dependencies, zero virtualenv overhead, native PyInstaller bundling.
- Designed decoupled storage:
get_bundle_dir()for read-only static assets,get_data_dir()for persistent SQLite database.
- Implemented and verified standalone verification suite (
proposed_verify.py): 8/8 tests passed.
- Implemented build automation script (
proposed_build.py) and PyInstaller onefile spec (proposed_HAD_Digital_onefile.spec).
- Produced comprehensive handoff report (
handoff.md) and unified patch (proposed_patches.patch).
