If `_docs/_autodev_state.md` exists → read the `flow` field and use that flow. (When a greenfield project completes its final cycle, the Done step rewrites `flow: existing-code` in-band so the next invocation enters the feature-cycle loop — see greenfield "Done".) +2. If the workspace is a **meta-repo** → **meta-repo flow**. Detected by: presence of `.gitmodules` with ≥2 submodules, OR `package.json` with `workspaces` field, OR `pnpm-workspace.yaml`, OR `Cargo.toml` with `[workspace]` section, OR `go.work`, OR an ad-hoc structure with multiple top-level component folders each containing their own project manifests. Optional tiebreaker: the workspace has little or no source code of its own at the root (just registry + orchestration files). +3. If workspace has **no source code files** → **greenfield flow** +4. If workspace has source code files **and** `_docs/` does not exist → **existing-code flow** +5. If workspace has source code files **and** `_docs/` exists → **existing-code flow** + +After selecting the flow, apply its detection rules (first match wins) to determine the current step. + +**Note**: the meta-repo flow uses a different artifact layout — its source of truth is `_docs/_repo-config.yaml`, not `_docs/NN_*/` folders. Other detection rules assume the BUILD-SHIP artifact layout; they don't apply to meta-repos. + +## Execution Loop + +Every invocation has three phases: **Bootstrap** (runs once), **Resolve** (runs once), **Execute Loop** (runs per step). Exit conditions are explicit. + +``` +### Bootstrap (once per invocation) +B1. Process leftovers — delegate to `.cursor/rules/tracker.mdc` → Leftovers Mechanism + (authoritative spec: replay rules, escalation, blocker handling). +B2. Surface Recent Lessons — print top 3 entries from `_docs/LESSONS.md` if present; skip silently otherwise. +B3. Read state — `_docs/_autodev_state.md` (if it exists). +B4. Read File Index — `state.md`, `protocols.md`, and the active flow file. + +### Resolve (once per invocation, after Bootstrap) +R1. Reconcile state — verify state file against `_docs/` contents; on disagreement, trust the folders + and update the state file (rules: `state.md` → "State File Rules" #4). + After this step, `state.step` / `state.status` are authoritative. +R2. Resolve flow — see §Flow Resolution above. +R3. Resolve current step — when a state file exists, `state.step` drives detection. + When no state file exists, walk the active flow's detection rules in order; + first folder-probe match wins. +R4. Present Status Summary — banner template in `protocols.md` + step-list fragment from the active flow file. + +### Execute Loop (per step) +loop: + E1. Delegate to the current skill (see §Skill Delegation below). + E2. On FAILED + → apply Failure Handling (`protocols.md`): increment retry_count, auto-retry up to 3. + → if retry_count reaches 3 → set status: failed → EXIT (escalate on next invocation). + E3. On success + → reset retry_count, update state file (rules: `state.md`). + E4. Re-detect next step from the active flow's detection rules. + E5. If the transition is marked as a session boundary in the flow's Auto-Chain Rules + → update state, present boundary Choose block, suggest new conversation → EXIT. + E6. If all steps done + → update state, report completion → EXIT. + E7. Else + → continue loop (go to E1 with the next skill). +``` + +## Skill Delegation + +For each step, the delegation pattern is: + +1. Update state file: set `step` to the autodev step number, status to `in_progress`, set `sub_step` to the sub-skill's current internal phase using the structured `{phase, name, detail}` schema (see `state.md`), reset `retry_count: 0` +2. Announce: "Starting [Skill Name]..." +3. Read the skill file: `.cursor/skills/[name]/SKILL.md` +4. Execute the skill's workflow exactly as written, including all BLOCKING gates, self-verification checklists, save actions, and escalation rules. Update `sub_step.phase`, `sub_step.name`, and optional `sub_step.detail` in state each time the sub-skill advances to a new internal phase. +5. If the skill **fails**: follow Failure Handling in `protocols.md` — increment `retry_count`, auto-retry up to 3 times, then escalate. +6. When complete (success): reset `retry_count: 0`, update state file to the next step with `status: not_started` and `sub_step: {phase: 0, name: awaiting-invocation, detail: ""}`, return to auto-chain rules (from active flow file) + +**sub_step read fallback**: when reading `sub_step`, parse the structured form. If parsing fails (legacy free-text value) OR the named phase is not recognized, log a warning and fall back to a folder scan of the sub-skill's artifact directory to infer progress. Do not silently treat a malformed sub_step as phase 0 — that would cause a sub-skill to restart from scratch after each resume. + +Do NOT modify, skip, or abbreviate any part of the sub-skill's workflow. The autodev is a sequencer, not an optimizer. + +## State File + +The state file (`_docs/_autodev_state.md`) is a minimal pointer — only the current step. See `state.md` for the authoritative template, field semantics, update rules, and worked examples. Do not restate the schema here — `state.md` is the single source of truth. + +## Trigger Conditions + +This skill activates when the user wants to: +- Start a new project from scratch +- Continue an in-progress project +- Check project status +- Let the AI guide them through the full workflow + +**Keywords**: "autodev", "auto", "start", "continue", "what's next", "where am I", "project status" + +**Invocation model**: this skill is explicitly user-invoked only (`disable-model-invocation: true` in the front matter).

After the document skill completes, re-detect state (the produced `_docs/` artifacts will place the project at Step 2 or later). + +The document skill's Step 2.5 produces `_docs/02_document/module-layout.md`, which is required by every downstream step that assigns file ownership (`/implement` Step 4, `/code-review` Phase 7, `/refactor` discovery). If this file is missing after Step 1 completes (e.g., a pre-existing `_docs/` dir predates the 2.5 addition), re-invoke `/document` in resume mode — it will pick up at Step 2.5. + +--- + +**Step 2 — Architecture Baseline Scan** +Condition: `_docs/02_document/FINAL_report.md` exists AND `_docs/02_document/architecture.md` exists AND `_docs/02_document/architecture_compliance_baseline.md` does not exist. + +Action: Invoke `.cursor/skills/code-review/SKILL.md` in **baseline mode** (Phase 1 + Phase 7 only) against the full existing codebase. Phase 7 produces a structural map of the code vs. the just-documented `architecture.md`. Save the output to `_docs/02_document/architecture_compliance_baseline.md`. + +Rationale: existing codebases often have pre-existing architecture violations (cycles, cross-component private imports, duplicate logic).

Without this step, hardcoded URLs, file paths, credentials, or global singletons can prevent the test suite from exercising the code against a controlled environment. The test authors need a testable surface before they can write tests that mean anything. + +**Scope — MINIMAL, SURGICAL fixes**: this is not a profound refactor. It is the smallest set of changes (sometimes temporary hacks) required to make code runnable under tests. "Smallest" beats "elegant" here — deeper structural improvements belong in Step 8 (Refactor), not this step. + +**Allowed changes** in this phase: +- Replace hardcoded URLs / file paths / credentials / magic numbers with env vars or constructor arguments. +- Extract narrow interfaces for components that need stubbing in tests. +- Add optional constructor parameters for dependency injection; default to the existing hardcoded behavior so callers do not break. +- Wrap global singletons in thin accessors that tests can override (thread-local / context var / setter gate). +- Split a huge function ONLY when necessary to stub one of its collaborators — do not split for clarity alone. + +**NOT allowed** in this phase (defer to Step 8 Refactor): +- Renaming public APIs (breaks consumers without a safety net). +- Moving code between files unless strictly required for isolation. +- Changing algorithms or business logic. +- Restructuring module boundaries or rewriting layers. + +**Safety**: Phase 3 (Safety Net) of the refactor skill is skipped here **by design** — no tests exist yet to form the safety net. Compensating controls: +- Every change is bounded by the allowed/not-allowed lists above. +- `list-of-changes.md` must be reviewed by the user BEFORE execution (refactor skill enforces this gate). +- After execution, the refactor skill produces `RUN_DIR/testability_changes_summary.md` — a plain-language list of every applied change and why.

Read `_docs/02_document/tests/traceability-matrix.md` and all test scenario files in `_docs/02_document/tests/`. +2. Read `_docs/02_document/architecture_compliance_baseline.md` (produced in Step 2). If it contains High/Critical Architecture findings that overlap with testability issues, consider including the lightest structural fixes inline; leave the rest for Step 8. +3. For each test scenario, check whether the code under test can be exercised in isolation.

Remove tests that lack data. Verify final coverage stays above 70%. -**Constraints**: This phase is MANDATORY and cannot be skipped. - -#### Step 1 — Build the test-data and expected-result requirements checklist - -Scan `blackbox-tests.md`, `performance-tests.md`, `resilience-tests.md`, `security-tests.md`, and `resource-limit-tests.md`. For every test scenario, extract: - -| # | Test Scenario ID | Test Name | Required Input Data | Required Expected Result | Result Quantifiable? | Comparison Method | Input Provided? | Expected Result Provided? | -|---|-----------------|-----------|---------------------|-------------------------|---------------------|-------------------|----------------|--------------------------| -| 1 | [ID] | [name] | [data description] | [what system should output] | [Yes/No] | [exact/tolerance/pattern/threshold] | [Yes/No] | [Yes/No] | - -Present this table to the user. - -#### Step 2 — Ask user to provide missing test data AND expected results - -For each row where **Input Provided?** is **No** OR **Expected Result Provided?** is **No**, ask the user: - -> **Option A — Provide the missing items**: Supply what is missing: -> - **Missing input data**: Place test data files in `_docs/00_problem/input_data/` or indicate the location. -> - **Missing expected result**: Provide the quantifiable expected result for this input. Update `_docs/00_problem/input_data/expected_results/results_report.md` with a row mapping the input to its expected output. If the expected result is complex, provide a reference CSV file in `_docs/00_problem/input_data/expected_results/`. Use `.cursor/skills/test-spec/templates/expected-results.md` for format guidance. -> -> Expected results MUST be quantifiable — the test must be able to programmatically compare actual vs expected. Examples: -> - "3 detections with bounding boxes [(x1,y1,x2,y2), ...] ± 10px" -> - "HTTP 200 with JSON body matching `expected_response_01.json`" -> - "Processing time < 500ms" -> - "0 false positives in the output set" -> -> **Option B — Skip this test**: If you cannot provide the data or expected result, this test scenario will be **removed** from the specification. - -**BLOCKING**: Wait for the user's response for every missing item. - -#### Step 3 — Validate provided data and expected results - -For each item where the user chose **Option A**: - -**Input data validation**: -1. Verify the data file(s) exist at the indicated location -2. Verify **quality**: data matches the format, schema, and constraints described in the test scenario (e.g., correct image resolution, valid JSON structure, expected value ranges) -3. Verify **quantity**: enough data samples to cover the scenario (e.g., at least N images for a batch test, multiple edge-case variants) - -**Expected result validation**: -4. Verify the expected result exists in `input_data/expected_results/results_report.md` or as a referenced file in `input_data/expected_results/` -5. Verify **quantifiability**: the expected result can be evaluated programmatically — it must contain at least one of: - - Exact values (counts, strings, status codes) - - Numeric values with tolerance (e.g., `± 10px`, `≥ 0.85`) - - Pattern matches (regex, substring, JSON schema) - - Thresholds (e.g., `< 500ms`, `≤ 5% error rate`) - - Reference file for structural comparison (JSON diff, CSV diff) -6. Verify **completeness**: the expected result covers all outputs the test checks (not just one field when the test validates multiple) -7. Verify **consistency**: the expected result is consistent with the acceptance criteria it traces to - -If any validation fails, report the specific issue and loop back to Step 2 for that item. - -#### Step 4 — Remove tests without data or expected results - -For each item where the user chose **Option B**: - -1. Warn the user: `⚠️ Test scenario [ID] "[Name]" will be REMOVED from the specification due to missing test data or expected result.` -2. Remove the test scenario from the respective test file -3. Remove corresponding rows from `traceability-matrix.md` -4. Update `test-data.md` to reflect the removal - -**Save action**: Write updated files under TESTS_OUTPUT_DIR: -- `test-data.md` -- Affected test files (if tests removed) -- `traceability-matrix.md` (if tests removed) - -#### Step 5 — Final coverage check - -After all removals, recalculate coverage: - -1. Count remaining test scenarios that trace to acceptance criteria -2. Count total acceptance criteria + restrictions -3. Calculate coverage percentage: `covered_items / total_items * 100` - -| Metric | Value | -|--------|-------| -| Total AC + Restrictions | ? | -| Covered by remaining tests | ? | -| **Coverage %** | **?%** | - -**Decision**: - -- **Coverage ≥ 70%** → Phase 3 **PASSED**. Present final summary to user. -- **Coverage < 70%** → Phase 3 **FAILED**. Report: - > ❌ Test coverage dropped to **X%** (minimum 70% required). The removed test scenarios left gaps in the following acceptance criteria / restrictions: - > - > | Uncovered Item | Type (AC/Restriction) | Missing Test Data Needed | - > |---|---|---| - > - > **Action required**: Provide the missing test data for the items above, or add alternative test scenarios that cover these items with data you can supply. - - **BLOCKING**: Loop back to Step 2 with the uncovered items. Do NOT finalize until coverage ≥ 70%. - -#### Phase 3 Completion - -When coverage ≥ 70% and all remaining tests have validated data AND quantifiable expected results: - -1. Present the final coverage report -2. List all removed tests (if any) with reasons -3. Confirm every remaining test has: input data + quantifiable expected result + comparison method -4.

However, hardware-dependent projects may require local execution to exercise the real code paths. This assessment determines the right execution strategy by scanning both documentation and source code. - -#### Step 1 — Documentation scan - -Check the following files for mentions of hardware-specific requirements: - -| File | Look for | -|------|----------| -| `_docs/00_problem/restrictions.md` | Platform requirements, hardware constraints, OS-specific features | -| `_docs/01_solution/solution.md` | Engine selection logic, platform-dependent paths, hardware acceleration | -| `_docs/02_document/architecture.md` | Component diagrams showing hardware layers, engine adapters | -| `_docs/02_document/components/*/description.md` | Per-component hardware mentions | -| `TESTS_OUTPUT_DIR/environment.md` | Existing environment decisions | - -#### Step 2 — Code scan - -Search the project source for indicators of hardware dependence. The project is **hardware-dependent** if ANY of the following are found: - -| Category | Code indicators (imports, APIs, config) | -|----------|-----------------------------------------| -| GPU / CUDA | `import pycuda`, `import tensorrt`, `import pynvml`, `torch.cuda`, `nvidia-smi`, `CUDA_VISIBLE_DEVICES`, `runtime: nvidia` | -| Apple Neural Engine / CoreML | `import coremltools`, `CoreML`, `MLModel`, `ComputeUnit`, `MPS`, `sys.platform == "darwin"`, `platform.machine() == "arm64"` | -| OpenCL / Vulkan | `import pyopencl`, `clCreateContext`, vulkan headers | -| TPU / FPGA | `import tensorflow.distribute.TPUStrategy`, FPGA bitstream loaders | -| Sensors / Cameras | `import cv2.VideoCapture(0)` (device index), serial port access, GPIO, V4L2 | -| OS-specific services | Kernel modules (`modprobe`), host-level drivers, platform-gated code (`sys.platform` branches selecting different backends) | - -Also check dependency files (`requirements.txt`, `setup.py`, `pyproject.toml`, `Cargo.toml`, `*.csproj`) for hardware-specific packages. - -#### Step 3 — Classify the project - -Based on Steps 1–2, classify the project: - -- **Not hardware-dependent**: no indicators found → use Docker (preferred default), skip to "Record the decision" below -- **Hardware-dependent**: one or more indicators found → proceed to Step 4 - -#### Step 4 — Present execution environment choice - -Present the findings and ask the user using Choose format: - -``` -══════════════════════════════════════ - DECISION REQUIRED: Test execution environment -══════════════════════════════════════ - Hardware dependencies detected: - - [list each indicator found, with file:line] -══════════════════════════════════════ - Running in Docker means these hardware code paths - are NOT exercised — Docker uses a Linux VM where - [specific hardware, e.g. CoreML / CUDA] is unavailable. - The system would fall back to [fallback engine/path]. -══════════════════════════════════════ - A) Local execution only (tests the real hardware path) - B) Docker execution only (tests the fallback path) - C) Both local and Docker (tests both paths, requires - two test runs — recommended for CI with heterogeneous - runners) -══════════════════════════════════════ - Recommendation: [A, B, or C] — [reason] -══════════════════════════════════════ -``` - -#### Step 5 — Record the decision - -Write or update a **"Test Execution"** section in `TESTS_OUTPUT_DIR/environment.md` with: - -1. **Decision**: local / docker / both -2. **Hardware dependencies found**: list with file references -3. **Execution instructions** per chosen mode: - - **Local mode**: prerequisites (OS, SDK, hardware), how to start services, how to run the test runner, environment variables - - **Docker mode**: docker-compose profile/command, required images, how results are collected - - **Both mode**: instructions for each, plus guidance on which CI runner type runs which mode +Read and follow `phases/hardware-assessment.md`. --- ### Phase 4: Test Runner Script Generation -**Skip condition**: If this skill was invoked from the `/plan` skill (planning context, no code exists yet), skip Phase 4 entirely. Script creation should instead be planned as a task during decompose — the decomposer creates a task for creating these scripts. Phase 4 only runs when invoked from the existing-code flow (where source code already exists) or standalone. - -**Role**: DevOps engineer -**Goal**: Generate executable shell scripts that run the specified tests, so the autopilot and CI can invoke them consistently. -**Constraints**: Scripts must be idempotent, portable across dev/CI, and exit with non-zero on failure. Respect the Docker Suitability Assessment decision above. - -#### Step 1 — Detect test infrastructure - -1. Identify the project's test runner from manifests and config files: - - Python: `pytest` (pyproject.toml, setup.cfg, pytest.ini) - - .NET: `dotnet test` (*.csproj, *.sln) - - Rust: `cargo test` (Cargo.toml) - - Node: `npm test` or `vitest` / `jest` (package.json) -2. Check Docker Suitability Assessment result: - - If **local execution** was chosen → do NOT generate docker-compose test files; scripts run directly on host - - If **Docker execution** was chosen → identify/generate docker-compose files for integration/blackbox tests -3. Identify performance/load testing tools from dependencies (k6, locust, artillery, wrk, or built-in benchmarks) -4. Read `TESTS_OUTPUT_DIR/environment.md` for infrastructure requirements - -#### Step 2 — Generate test runner - -**Docker is the default.** Only generate a local `scripts/run-tests.sh` if the Hardware-Dependency Assessment determined **local** or **both** execution (i.e., the project requires real hardware like GPU/CoreML/TPU/sensors). For all other projects, use `docker-compose.test.yml` — it provides reproducibility, isolation, and CI parity without a custom shell script. - -**If local script is needed** — create `scripts/run-tests.sh` at the project root using `.cursor/skills/test-spec/templates/run-tests-script.md` as structural guidance. The script must: - -1. Set `set -euo pipefail` and trap cleanup on EXIT -2. **Install all project and test dependencies** (e.g. `pip install -q -r requirements.txt -r e2e/requirements.txt`, `dotnet restore`, `npm ci`). This prevents collection-time import errors on fresh environments. -3. Optionally accept a `--unit-only` flag to skip blackbox tests -4. Run unit/blackbox tests using the detected test runner (activate virtualenv if present, run test runner directly on host) -5. Print a summary of passed/failed/skipped tests -6. Exit 0 on all pass, exit 1 on any failure - -**If Docker** — generate or update `docker-compose.test.yml` that builds the test image, installs all dependencies inside the container, runs the test suite, and exits with the test runner's exit code. - -#### Step 3 — Generate `scripts/run-performance-tests.sh` - -Create `scripts/run-performance-tests.sh` at the project root. The script must: - -1. Set `set -euo pipefail` and trap cleanup on EXIT -2. Read thresholds from `_docs/02_document/tests/performance-tests.md` (or accept as CLI args) -3. Start the system under test (local or docker-compose, matching the Docker Suitability Assessment decision) -4. Run load/performance scenarios using the detected tool -5. Compare results against threshold values from the test spec -6. Print a pass/fail summary per scenario -7. Exit 0 if all thresholds met, exit 1 otherwise - -#### Step 4 — Verify scripts - -1.

Key Architectural Decisions + +### ADR-001: Cython for IP Protection + +**Context**: The loader handles encryption keys and security-sensitive logic that should not be trivially readable. + +**Decision**: Core modules (api_client, security, cdn_manager, hardware_service, credentials, user, constants) are written in Cython and compiled to native `.so` extensions. + +**Alternatives considered**: +1. Pure Python with obfuscation — rejected because obfuscation is reversible +2. Compiled language (Rust/Go) — rejected because of tighter integration needed with Python ecosystem (FastAPI, boto3) + +**Consequences**: Build step required (`setup.py build_ext --inplace`); `cdef` methods not callable from pure Python; debugging compiled extensions is harder. + +### ADR-002: Binary-Split Resource Scheme + +**Context**: Large model files need secure distribution. Storing entire encrypted files on one server creates a single point of compromise. + +**Decision**: Resources are encrypted, then split into a small part (uploaded to the authenticated API) and a large part (uploaded to CDN). Decryption requires both parts. + +**Alternatives considered**: +1. Single encrypted download from API — rejected because of bandwidth/cost for large files +2. Unencrypted CDN with signed URLs — rejected because CDN compromise would expose models + +**Consequences**: More complex download/upload logic; local caching of big parts for performance; CDN credentials managed separately from API credentials. + +### ADR-003: Docker-in-Docker for Image Loading + +**Context**: The loader needs to inject Docker images into the host Docker daemon on edge devices. + +**Decision**: Mount Docker socket into the loader container; use Docker CLI (`docker load`, `docker image inspect`) via subprocess. + +**Alternatives considered**: +1. Docker API via Python library — rejected because Docker CLI is simpler and universally available +2. Image loading outside the loader — rejected because the unlock workflow needs to be self-contained + +**Consequences**: Container requires Docker socket mount (security implication); Docker CLI must be installed in the container image. diff --git a/_docs/02_document/components/01_core_models/description.md b/_docs/02_document/components/01_core_models/description.md new file mode 100644 index 0000000..10601d2 --- /dev/null +++ b/_docs/02_document/components/01_core_models/description.md @@ -0,0 +1,98 @@ +# Core Models + +## 1.

This is a business process change, not just a code change. + +4. **Known stability issues** — Forum reports of PCR values and NV handles not persisting across reboots.

The threat is physical access to an untrusted device. + +### Reference Comparison +On Jetson Orin Nano with fTPM (Fact #2): the encryption key is derived from hardware fuses. Even with full disk access, the attacker cannot extract the key without the specific TPM hardware. The device itself is the trust anchor, not the storage distribution. + +### Conclusion +For TPM-equipped devices, split-storage adds complexity without adding security. The TPM hardware binding is strictly stronger than distributing fragments across servers. Binary-split's security purpose is obsolete on TPM devices. + +### Confidence +✅ High — hardware-fuse-derived keys are fundamentally stronger than software-computed hashes. + +--- + +## Dimension 2: Is CDN offloading still valuable without split? + +### Fact Confirmation +ADR-002 lists two reasons for binary-split (Fact #20): (1) security (prevent single-point compromise) and (2) bandwidth/cost (large files on CDN, small metadata on API). + +### Reference Comparison +If security is handled by TPM device binding, the CDN offloading benefit remains valid for large AI models. But the *splitting* mechanism (small+big parts) is unnecessary — a single encrypted file on CDN with an authenticated download URL achieves the same bandwidth benefit. + +### Conclusion +CDN usage should remain for bandwidth optimization. But the split-and-merge encryption scheme can be replaced by a simpler pattern: encrypt the whole resource with a TPM-sealed key, store on CDN, download as single file. + +### Confidence +✅ High — bandwidth and security are orthogonal concerns. + +--- + +## Dimension 3: Can tpm2-pytss integrate with the Cython codebase? + +### Fact Confirmation +tpm2-pytss (Fact #9, #17) is a Python library calling native tpm2-tss via CFFI. It provides FAPI with create_seal, unseal, encrypt, decrypt. The loader's security module is Cython (.pyx) calling Python cryptographic libraries. + +### Reference Comparison +The current security.pyx already calls Python libraries (cryptography.hazmat). tpm2-pytss follows the same pattern — Python calls to a native library. Cython can call tpm2-pytss the same way. + +### Conclusion +No architectural barrier. tpm2-pytss integrates naturally alongside existing cryptography library usage. + +### Confidence +✅ High — same integration pattern as existing code. + +--- + +## Dimension 4: What about SaaS/non-TPM deployments? + +### Fact Confirmation +The loader now runs on both Jetson edge devices and SaaS web servers (Fact #11). TPM is machine-specific — works for fixed edge devices but SaaS VMs may not have TPM (or have vTPM with different trust properties). + +### Reference Comparison +Alternative approaches exist for non-TPM environments (Fact #18): signed manifests, asymmetric signature verification, authenticated downloads. For SaaS servers that the company controls, the threat model is different — the server is trusted, so split-storage is unnecessary even without TPM. + +### Conclusion +Two-tier strategy: (1) Jetson devices use TPM-sealed keys for strongest binding; (2) SaaS servers use standard authenticated download (no split needed since server is trusted infrastructure). The binary-split complexity is needed for neither scenario. + +### Confidence +✅ High — different deployment contexts have different threat models. + +--- + +## Dimension 5: fTPM production readiness + +### Fact Confirmation +Forum reports (Fact #5, #6): PCR7 values not persisting across reboots; NV handles lost after reboot. RPMB not available on Orin Nano (Fact #16) — only REE FS. + +### Reference Comparison +The proposed design does NOT rely on PCR-sealed keys or NV indexes. The key workflow uses FAPI create_seal/unseal with the Storage Root Key (SRK) hierarchy, which derives from the hardware fuse seed (Fact #2). This is independent of PCR persistence and NV storage issues. + +### Conclusion +The PCR/NV persistence bugs are not blocking for this use case. FAPI seal/unseal under the SRK hierarchy uses the persistent primary key derived from fuses, not PCR-gated policies. However, this should be validated on actual hardware before committing. + +### Confidence +⚠️ Medium — reasoning is sound but needs hardware validation. + +--- + +## Dimension 6: Manufacturing pipeline impact + +### Fact Confirmation +fTPM provisioning requires (Fact #3, #4): per-device KDK0 generation, fuse burning, EK certificate via CA, EKB encoding. Only offline provisioning supported. + +### Reference Comparison +The current loader requires no manufacturing-time setup — credentials are provided at runtime. Adding fTPM provisioning is a significant operational change. + +### Conclusion +fTPM provisioning is the biggest non-code cost. However, if Jetson devices are already manufactured by an OEM partner, fTPM provisioning can be integrated into the existing flashing pipeline. For development/testing, a simulated TPM (swtpm) can be used. + +### Confidence +⚠️ Medium — depends on OEM manufacturing pipeline. + +--- + +## Dimension 7: Migration path + +### Fact Confirmation +Existing deployments use binary-split. New deployments can use TPM. Both must coexist during transition. + +### Reference Comparison +Feature-flag pattern: detect at startup whether /dev/tpm0 exists and is provisioned. If yes, use TPM key path. If no, fall back to legacy binary-split. The API contracts (F1-F6) remain unchanged — the security layer is internal. + +### Conclusion +A SecurityProvider abstraction (interface) with two implementations (LegacySecurityProvider, TpmSecurityProvider) enables clean coexistence. Detection is automatic.

The entire fusing and provisioning process runs on a standard PC. + +### 1.2 Roles: ODM vs OEM + +NVIDIA's fTPM docs describe two separate entities: + +- **ODM (Original Design Manufacturer)**: Designs the fTPM integration, generates KDK0 per device, runs the CA server, signs EK certificates, creates firmware packages. +- **OEM (Original Equipment Manufacturer)**: Adds disk encryption keys, assembles hardware, burns fuses at the factory, ships the final product. + +In large-scale manufacturing these are different companies with a formal key handoff. **In our case, we are both ODM and OEM** — we design, provision, flash, and deploy ourselves. NVIDIA covers this in their fTPM guide Appendix B with a **simplified single-entity flow** that eliminates the cross-company handoff and roughly halves the provisioning complexity. + +### 1.3 Key Derivation Chain + +The full derivation from hardware fuses to usable keys: + +``` +KDK0 (256-bit random, burned into SoC fuses at manufacturing) +│ +├── Silicon_ID = KDF(key=KDK0, info=Device_SN) +│ Device_SN = OEM_ID || SN (unique per device) +│ +├── fTPM_Seed = KDF(key=Silicon_ID, constant_str1) +│ Passed from MB2 bootloader to OP-TEE via encrypted TrustZone memory +│ +├── fTPM_Root_Seed = KDF(key=fTPM_Seed, constant_str) +│ +├── EPS = KDF(key=fTPM_Root_Seed, info=Device_SN, salt=EPS_Seed) +│ EPS_Seed is a 256-bit random number from odm_ekb_gen.py, stored in EKB +│ EPS (Endorsement Primary Seed) is the root identity of the fTPM entity +│ +├── SRK = TPM2_CreatePrimary(EPS) +│ Deterministic — re-derived from EPS on every boot +│ Never stored persistently, never leaves the secure world +│ +└── Sealed blobs (your encryption keys) + Encrypted under SRK, stored as files on disk + Only unsealable on this specific device +``` + +Every KDF step is one-way. Knowing a derived value does not reveal its parent. Two devices with different KDK0 values produce entirely different key trees. + +### 1.4 Provisioning Process (Single-Entity / ODM+OEM Flow) + +#### Step 1: Install BSP and FSKP Packages + +``` +mkdir ${BSP_TOP} && cd ${BSP_TOP} +tar jvxf jetson_linux_${rel_ver}_aarch64.tbz2 +tar jvxf public_sources.tbz2 +cd Linux_for_Tegra/rootfs +sudo tar jvxpf tegra_linux_sample-root-filesystem_${rel_ver}_aarch64.tbz2 +cd ${BSP_TOP}/Linux_for_Tegra +sudo ./apply_binaries.sh +cd ${BSP_TOP} +tar jvxf fskp_partner_t234_${rel_ver}_aarch64.tbz2 +``` + +#### Step 2: Generate PKC and SBK Keys (Secure Boot) + +``` +openssl genrsa -out pkc.pem 3072 +python3 gen_sbk_key.py --out sbk.key +``` + +PKC (Public Key Cryptography) key signs all boot chain images. SBK (Secure Boot Key) encrypts them. Both are burned into fuses and used for every subsequent flash. + +#### Step 3: Generate Per-Device KDK0 and Silicon_ID + +``` +python3 kdk_gen.py \ + --oem-id ${OEM_ID} \ + --sn ${DEVICE_SN} \ + --output-dir ${KDK_DB} +``` + +Outputs per device: KDK0 (256-bit), Device_SN, Silicon_ID public key. **KDK0 must be discarded after the fuseblob and EKB are generated** — keeping it in storage risks leaks. + +#### Step 4: Generate Fuseblob + +``` +python3 fskp_fuseburn.py \ + --kdk-db ${KDK_DB} \ + --pkc-key pkc.pem \ + --sbk-key sbk.key \ + --fuse-xml fuse_config.xml \ + --output-dir ${FUSEBLOB_DB} +``` + +The fuse config XML specifies which fuses to burn: KDK0, PKC hash, SBK, OEM_K1, SECURITY_MODE, ARM_JTAG_DISABLE, etc. + +#### Step 5: Generate fTPM EKB (EK Certificates + EPS Seed) + +``` +python3 odm_ekb_gen.py \ + --kdk-db ${KDK_DB} \ + --output-dir ${EKB_FTPM_DB} +``` + +This generates EK CSRs, signs them with your CA, and packages the EPS Seed + EK certificates into per-device EKB images. In the single-entity flow, you run your own CA: + +``` +python3 ftpm_manufacturer_ca_simulator.sh # Replace with real CA in production +``` + +Then merge with disk encryption keys: + +``` +python3 oem_ekb_gen.py \ + --ekb-ftpm-db ${EKB_FTPM_DB} \ + --user-keys sym2_t234.key \ + --oem-k1 oem_k1.key \ + --output-dir ${EKB_FINAL_DB} +``` + +#### Step 6: Burn Fuses (IRREVERSIBLE) + +Put the device in USB recovery mode: + +- If powered off: connect DC power (device enters recovery automatically on some carrier boards) +- If powered on: `sudo reboot --force forced-recover` +- Verify: `lsusb` shows NVIDIA device + +Test first (dry run): + +``` +sudo ./odmfuse.sh --test -X fuse_config.xml -i 0x23 jetson-orin-nano-devkit +``` + +Burn for real: + +``` +sudo ./odmfuse.sh -X fuse_config.xml -i 0x23 jetson-orin-nano-devkit +``` + +After `SECURITY_MODE` fuse is burned (value 0x1), **all further fuse writes are blocked permanently** (except a few ODM-reserved fuses). + +#### Step 7: Flash Signed + Encrypted Images + +``` +sudo ROOTFS_ENC=1 ./flash.sh \ + -u pkc.pem \ + -v sbk.key \ + -i ./sym2_t234.key \ + --ekb ${EKB_FINAL_DB}/ekb-${DEVICE_SN}.signed \ + jetson-orin-nano-devkit \ + nvme0n1p1 +``` + +#### Step 8: On-Device fTPM Provisioning (One-Time) + +After first boot, run the provisioning script on the device: + +``` +sudo ./ftpm_provisioning.sh +``` + +This queries EK certificates from the EKB, stores them in fTPM NV memory, takes fTPM ownership, and creates EK handles. Only needs to run once per device. + +### 1.5 Difficulty Assessment + + +| Aspect | Difficulty | Notes | +| ----------------------------- | ------------------- | ---------------------------------------------------- | +| First device (learning curve) | Medium-High | NVIDIA docs are detailed but dense. Budget 2-3 days. | +| Subsequent devices (scripted) | Low | Same pipeline, different KDK0/SN per device. | +| Risk | High (irreversible) | Always test on expendable dev board first. | +| Automation potential | High | Entire pipeline is scriptable for factory floor. | + + +### 1.6 Known Issues + +- `odmfuseread.sh` has a Python 3 compatibility bug: `getiterator()` deprecated. Fix: replace line 1946 in `tegraflash_impl_t234.py` with `xml_tree.iter('file')`. +- Forum reports of PCR7 values not persisting across reboots. Our design deliberately avoids PCR-sealed keys — we use FAPI seal/unseal under SRK hierarchy only. +- Forum reports of NV handle loss after reboot on some Orin devices. Not blocking for our use case (SRK is re-derived from fuses, not stored in NV). + +--- + +## 2. Storage Encryption + +### 2.1 Recommendation: Full-Disk Encryption + +Encrypt the entire NVMe rootfs partition, not just selected model files. + +**Why full disk instead of selective encryption:** + + +| Approach | Protects models | Protects logs/config/temp files | Custom code needed | Performance | +| ---------------------------- | --------------- | ------------------------------------------------ | --------------------------------------- | ---------------------------- | +| Selective (model files only) | Yes | No — metadata, logs, decrypted artifacts exposed | Yes — application-level encrypt/decrypt | Minimal | +| Full disk (LUKS) | Yes | Yes — everything on disk is ciphertext | No — kernel handles it transparently | Minimal (HW-accelerated AES) | + + +Full-disk encryption is built into NVIDIA's Jetson Linux stack. No application code changes needed for the disk layer. + +### 2.2 How Full-Disk Encryption Works + +``` +Flashing (host PC): + gen_ekb → sym2_t234.key (DEK) + eks_t234.img (EKB image) + ROOTFS_ENC=1 flash.sh → rootfs encrypted with DEK, DEK packaged in EKB + +Boot (on device): + MB2 reads KDK0 from fuses + → derives K1 + → decrypts EKB + → extracts DEK + → passes DEK to dm-crypt kernel module + dm-crypt + LUKS mounts rootfs transparently + Application sees a normal filesystem — encryption is invisible +``` + +The application never touches the disk encryption key. It's handled entirely in the kernel, initialized before the OS starts. + +### 2.3 Double Encryption (Defense in Depth) + +For AI model files, two independent encryption layers: + +1. **Layer 1 — Full Disk LUKS** (kernel): Protects everything on disk. Key derived from fuses via EKB. Transparent to applications. +2. **Layer 2 — Application-level TPM-sealed encryption**: Model files encrypted with a key sealed in the fTPM. Decrypted by the loader at runtime. + +An attacker who somehow bypasses disk encryption (e.g., cold boot while the filesystem is mounted) still faces the application-level encryption. And vice versa. + +### 2.4 Setup Steps + +1. Generate encryption keys from OP-TEE source: + ``` + cd ${BSP_TOP}/Linux_for_Tegra/source/nvidia-jetson-optee-source + cd optee/samples/hwkey-agent/host/tool/gen_ekb/ + sudo chmod +x example.sh && ./example.sh + ``` + Outputs: `sym2_t234.key` (DEK) and `eks_t234.img` (EKB image). +2. Place keys: + ``` + cp sym2_t234.key ${BSP_TOP}/Linux_for_Tegra/ + cp eks_t234.img ${BSP_TOP}/Linux_for_Tegra/bootloader/ + ``` +3. Verify EKB integrity: + ``` + hexdump -C -n 4 -s 0x24 eks_t234.img + # Must show magic bytes "EEKB" + ``` +4. Configure NVMe partition size in `flash_l4t_t234_nvme_rootfs_enc.xml`: + - Set `NUM_SECTORS` based on NVMe capacity (e.g., 900000000 for 500GB) + - Set `encrypted="true"` for the rootfs partition +5. Flash with encryption: + ``` + sudo ROOTFS_ENC=1 ./tools/kernel_flash/l4t_initrd_flash.sh \ + --external-device nvme0n1p1 \ + -c flash_l4t_t234_nvme_rootfs_enc.xml \ + -i ./sym2_t234.key \ + -u pkc.pem -v sbk.key \ + jetson-orin-nano-devkit \ + nvme0n1p1 + ``` + +--- + +## 3. Debug Access Strategy + +### 3.1 The Problem + +After Secure Boot fusing, JTAG disabling, and OS hardening, the device has no interactive access. How do you develop, debug, and perform field maintenance? + +### 3.2 Solution: Dual-Image Approach + +Standard embedded Linux practice: maintain two OS images, both signed with the same PKC key. + + +| Property | Development Image | Production Image | +| ---------------------------------- | --------------------------------- | ----------------------- | +| Secure Boot signature | Signed with PKC key | Signed with PKC key | +| Boots on fused device | Yes | Yes | +| SSH access | Yes (key-based only, no password) | No (sshd not installed) | +| Serial console | Enabled | Disabled | +| ptrace / /dev/mem | Allowed | Blocked (lockdown mode) | +| Debug tools (gdb, strace, tcpdump) | Installed | Not present | +| Getty on TTY | Running | Not spawned | +| Desktop environment | Optional | Not installed | +| Application | Your loader + inference | Your loader + inference | + + +Secure Boot verifies the **signature**, not the **contents** of the image. Both images are valid as long as they're signed with your PKC key. An attacker cannot create either image without the private key. + +### 3.3 Workflow + +**During development:** + +1. Flash the dev image to a fused device +2. SSH in via key-based authentication +3. Develop, debug, iterate +4. When done, flash the prod image for deployment + +**Production deployment:** + +1. Flash the prod image at the factory +2. Device boots directly into your application +3. No shell, no SSH, no serial — only your FastAPI endpoints + +**Field debug (emergency):** + +1. Connect host PC via USB-C +2. Put device in USB recovery mode (silicon ROM, always available) +3. Reflash with the dev image (requires PKC private key to sign) +4. SSH in, diagnose, fix +5. Reflash with prod image, redeploy + +USB recovery mode is hardwired in silicon. It always works regardless of what OS is installed. But after Secure Boot fusing, it **only accepts images signed with your PKC key**. An attacker who enters recovery mode but lacks the signing key is stuck. + +### 3.4 Optional: Hardware Debug Jumper + +A physical GPIO pin on the carrier board that, when shorted at boot, tells the init system to start SSH: + +``` +Boot → systemd reads GPIO pin → if HIGH: start sshd.service + → if LOW: sshd not started (production behavior) +``` + +Opening the case to access the jumper triggers the tamper enclosure → keys are zeroized. So this is only useful during controlled maintenance with the tamper system temporarily disarmed. + +### 3.5 PKC Key Security + +The PKC private key is the crown jewel. Whoever holds it can create signed images that boot on any of your fused devices. Protect it accordingly: + +- Store on an air-gapped machine or HSM (Hardware Security Module) +- Never store in git, CI/CD pipelines, or cloud storage +- Limit access to 1-2 people +- Consider splitting with Shamir's Secret Sharing for key ceremonies + +--- + +## 4.

binary-split resource scheme (ADR-002) where encrypted resources are split into a small part (uploaded to the authenticated API) and a large part (uploaded to CDN). Decryption requires both parts. This was designed for distributing AI models to **end-user laptops** where the device is untrusted — the loader shipped 99% of the model in the installer, and the remaining 1% (first 3KB) was downloaded at runtime to prevent extraction. + +The distribution model has shifted to **SaaS** — services now run on web servers or **Jetson Orin Nano** edge devices. The Jetson Orin Nano includes a **TPM (Trusted Platform Module)** that can provide hardware-rooted security, potentially making the binary-split mechanism unnecessary overhead. + +## Current Security Architecture + +- **Binary-split scheme**: Resources encrypted with AES-256-CBC, split into small (≤3KB or 30%) + big parts, stored on separate servers (API + CDN) +- **Key derivation**: SHA-384 hashes combining email, password, hardware fingerprint, and salt +- **Docker unlock**: Key fragment downloaded from API, used to decrypt encrypted Docker image archive +- **Hardware binding**: SHA-384 hash of hardware fingerprint ties decryption to specific hardware +- **Cython compilation**: Core modules compiled to .so for IP protection + +## Questions to Investigate + +1. **TPM capabilities on Jetson Orin Nano**: What TPM version is available? What crypto operations does it support (key sealing, attestation, secure storage)? How does NVIDIA's security stack integrate with standard TPM APIs? + +2. **TPM-based key management**: Can TPM replace the current key derivation scheme (SHA-384 of email+password+hw_hash+salt)? Can keys be sealed to TPM PCR values so they're only accessible on the intended device? + +3. **Eliminating binary-split**: If TPM provides hardware-rooted trust (device can prove it's authentic), is the split-storage security model still necessary? Could the loader become a standard authenticated resource downloader with TPM-backed decryption? + +4. **Docker image protection**: Can TPM-based disk encryption or sealed storage replace the current encrypted-archive-plus-key-fragment approach for Docker images? + +5. **Migration path**: How would the transition work for existing deployments? Can both models (binary-split for legacy, TPM for new) coexist? + +6. **Threat model comparison**: What threats does binary-split protect against that TPM doesn't (and vice versa)? Are there attack vectors specific to Jetson Orin Nano that need consideration? + +7. **Implementation complexity**: What libraries/tools are available for TPM on ARM64/Jetson? (tpm2-tools, python-tpm2-pytss, etc.) What's the integration effort? + +## Constraints + +- Must support ARM64 (Jetson Orin Nano specifically) +- Must work within Docker containers (loader runs as a container with Docker socket mount) +- Cannot break existing API contracts (F1-F6 flows) +- Cython compilation requirement remains for IP protection +- Need to consider both SaaS web server and Jetson edge device deployments diff --git a/_docs/02_tasks/_dependencies_table.md b/_docs/02_tasks/_dependencies_table.md new file mode 100644 index 0000000..ee8a363 --- /dev/null +++ b/_docs/02_tasks/_dependencies_table.md @@ -0,0 +1,70 @@ +# Dependencies Table + +**Date**: 2026-04-15 +**Total Tasks**: 14 +**Total Complexity Points**: 55 + +## Completed Tasks (Blackbox Tests & Refactoring) + +| Task | Name | Complexity | Dependencies | Epic | +|------|------|-----------|-------------|------| +| 01 | test_infrastructure | 5 | None | Blackbox Tests | +| 02 | test_health_auth | 3 | 01 | Blackbox Tests | +| 03 | test_resources | 5 | 01, 02 | Blackbox Tests | +| 04 | test_unlock | 5 | 01, 02 | Blackbox Tests | +| 05 | test_resilience_perf | 3 | 01, 02 | Blackbox Tests | +| 06 | refactor_crypto_uploads | 3 | None | 01-quality-cleanup | +| 07 | refactor_thread_safety | 3 | None | 01-quality-cleanup | +| 08 | refactor_cleanup | 2 | 06 | 01-quality-cleanup | + +## Active Tasks (Loader Security Modernization) + +| Task | Name | Complexity | Dependencies | Epic | +|------|------|-----------|-------------|------| +| AZ-182 | tpm_security_provider | 5 | None | AZ-181 | +| AZ-183 | resources_table_update_api | 3 | None | AZ-181 | +| AZ-184 | resumable_download_manager | 3 | None | AZ-181 | +| AZ-185 | update_manager | 5 | AZ-183, AZ-184 | AZ-181 | +| AZ-186 | cicd_artifact_publish | 3 | AZ-183 | AZ-181 | +| AZ-187 | device_provisioning_script | 2 | None | AZ-181 | + +## Execution Batches (AZ-181 Epic) + +| Batch | Tasks | Parallel?

Under concurrent requests, two threads could create separate instances, the second overwriting the first. + +**Issue 2 — Global mutable unlock state**: `unlock_state` and `unlock_error` are module-level globals in `main.py`. They are protected by `unlock_lock` for writes, but the pattern of global state makes reasoning about state transitions harder and prevents running multiple unlock sequences. + +**Issue 3 — Manual PKCS7 unpadding**: `security.pyx:38-44` manually reads the last byte to determine padding length, but does not validate that all N trailing bytes equal N (as PKCS7 requires). Corrupted or tampered ciphertext silently produces garbage. If the last byte is outside 1-16, data is returned as-is with no error. The library's `padding.PKCS7(128).unpadder()` is already imported (line 8) and used for encryption — the same should be used for decryption. The same manual pattern exists in `binary_split.py:46-53` for archive decryption. + +**Issue 4 — Hardcoded log path**: `constants.pyx:20` writes to `"Logs/log_loader_{time:YYYYMMDD}.txt"` with no environment variable override. Works in Docker where `/app/Logs/` is the implicit path, but breaks or creates unexpected directories in other environments. + +**Issue 5 — Silent error swallowing**: `main.py:143-146` catches `OSError` on `os.remove(tar_path)` and passes silently. Per project rules, errors should not be silently suppressed. + +**Issue 6 — Dead code**: 5 orphan methods in `api_client.pyx` (`get_user`, `list_files`, `check_resource`, `upload_to_cdn`, `download_from_cdn`) — defined and declared in `.pxd` but never called from any source file. 5 orphan constants in `constants.pyx` (`CONFIG_FILE`, `QUEUE_CONFIG_FILENAME`, `AI_ONNX_MODEL_FILE`, `MODELS_FOLDER`, `ALIGNMENT_WIDTH`) — declared but never referenced outside their own file.

Concurrent requests can create duplicate instances, with the second overwriting the first. +- **Change**: Protect the singleton initialization with a `threading.Lock` using the double-checked locking pattern. +- **Rationale**: FastAPI serves concurrent requests via threads; the global singleton must be safe under concurrency. +- **Risk**: low +- **Dependencies**: None + +### C02: Encapsulate unlock state +- **File(s)**: main.py +- **Problem**: `unlock_state` and `unlock_error` are module-level globals mutated via a lock. This pattern scatters state management across the module and makes the state machine hard to reason about. +- **Change**: Move unlock state and error into a small state holder class that encapsulates the lock and provides thread-safe read/write methods. +- **Rationale**: Single Responsibility — state management belongs in one place, not spread across endpoint handlers and background tasks. +- **Risk**: low +- **Dependencies**: None + +### C03: Use library PKCS7 unpadder in Security.decrypt_to +- **File(s)**: security.pyx +- **Problem**: `decrypt_to` manually reads the last byte to determine padding length. It does not validate that all N trailing bytes equal N (PKCS7 requirement). Corrupted ciphertext silently produces garbage. The `padding.PKCS7(128).unpadder()` is already imported but unused for decryption. +- **Change**: Replace manual unpadding (lines 38-44) with the library's `padding.PKCS7(128).unpadder()`, matching the encrypt path. +- **Rationale**: The library validates all padding bytes and raises on corruption instead of silently returning garbage. +- **Risk**: medium — changes decryption output on invalid input (correctly raises instead of silently passing) +- **Dependencies**: None + +### C04: Use library PKCS7 unpadder in decrypt_archive +- **File(s)**: binary_split.py +- **Problem**: `decrypt_archive` manually reads the last byte of the decrypted file to strip padding (lines 46-53). Same incomplete PKCS7 validation as C03. +- **Change**: After decryption, use the `cryptography` library's PKCS7 unpadder to strip padding instead of manual byte inspection and file truncation. +- **Rationale**: Same as C03 — proper validation, raises on corruption. +- **Risk**: medium — same reasoning as C03 +- **Dependencies**: None + +### C05: Configurable log file path +- **File(s)**: constants.pyx +- **Problem**: Log file sink is hardcoded to `"Logs/log_loader_{time:YYYYMMDD}.txt"`. No environment variable override. Creates unexpected directories outside Docker. +- **Change**: Read the log directory from an environment variable (e.g., `LOG_DIR`) with the current value as default. +- **Rationale**: Configurability across development and production environments. +- **Risk**: low +- **Dependencies**: None + +### C06: Log os.remove failure instead of swallowing +- **File(s)**: main.py +- **Problem**: `os.remove(tar_path)` catches `OSError` and passes silently (lines 143-146). Hides information about filesystem issues. +- **Change**: Log the exception at warning level instead of silently passing. +- **Rationale**: Per project rules, errors should not be silently suppressed. +- **Risk**: low +- **Dependencies**: None + +### C07: Remove dead methods from ApiClient +- **File(s)**: api_client.pyx, api_client.pxd +- **Problem**: 5 methods are defined and declared but never called from any source file: `get_user`, `list_files`, `check_resource`, `upload_to_cdn`, `download_from_cdn`. +- **Change**: Delete the 5 orphan method definitions from `api_client.pyx` and their declarations from `api_client.pxd`. +- **Rationale**: Dead code misleads readers and breaks when its dependencies evolve. Git history preserves it. +- **Risk**: low +- **Dependencies**: None + +### C08: Remove dead constants +- **File(s)**: constants.pyx, constants.pxd +- **Problem**: 5 constants in `constants.pyx` are never referenced outside their own file: `CONFIG_FILE`, `QUEUE_CONFIG_FILENAME`, `AI_ONNX_MODEL_FILE`, `MODELS_FOLDER`, `ALIGNMENT_WIDTH`. Additionally, 3 variables are declared in `constants.pxd` with no definition in `constants.pyx`: `QUEUE_MAXSIZE`, `COMMANDS_QUEUE`, `ANNOTATIONS_QUEUE`. +- **Change**: Delete the 5 unused constant definitions from `constants.pyx` and all 8 orphan declarations from `constants.pxd` (keeping only `CDN_CONFIG`, `SMALL_SIZE_KB`, `log`, `logerror`). +- **Rationale**: Dead code rots. Orphan `.pxd` declarations with no backing definition are especially misleading. +- **Risk**: low +- **Dependencies**: None + +### C09: CDN upload failure silently ignored +- **File(s)**: api_client.pyx +- **Problem**: `upload_big_small_resource` (line 203) calls `self.cdn_manager.upload()` which returns `False` on failure, but the return value is never checked. A failed CDN upload means the big part is only saved locally — the resource cannot be downloaded from other devices. +- **Change**: Check the return value of `cdn_manager.upload` and raise on failure, matching the pattern in the (currently orphan) `upload_to_cdn` method. +- **Rationale**: Silent upload failure leads to incomplete resources that cannot be downloaded from CDN on other devices. +- **Risk**: medium — previously-silent failures will now raise exceptions +- **Dependencies**: None + +### C10: API upload failure silently swallowed +- **File(s)**: api_client.pyx +- **Problem**: `upload_file` (line 91-102) catches all exceptions and only logs them. The caller (`upload_big_small_resource` at line 206) never knows the API upload failed. The small part is silently lost. +- **Change**: Let the exception propagate to the caller instead of catching and logging. The caller's error handling (main.py endpoint) will convert it to an appropriate HTTP error. +- **Rationale**: The upload endpoint should report failure, not return `{"status": "ok"}` when the small part was never uploaded. +- **Risk**: medium — previously-silent failures will now raise exceptions +- **Dependencies**: None diff --git a/_docs/04_refactoring/01-quality-cleanup/test_specs/existing_coverage.md b/_docs/04_refactoring/01-quality-cleanup/test_specs/existing_coverage.md new file mode 100644 index 0000000..8e076b5 --- /dev/null +++ b/_docs/04_refactoring/01-quality-cleanup/test_specs/existing_coverage.md @@ -0,0 +1,30 @@ +# Existing Test Coverage Assessment + +**Suite**: 18 e2e blackbox tests (all passing) +**Runner**: pytest via scripts/run-tests.sh +**Last run**: 18 passed, 0 failed, 0 skipped (12.87s) + +## Coverage by Change + +| Change | Files | Covered By | Coverage | +|--------|-------|------------|----------| +| C03 | security.pyx (decrypt_to) | test_upload_download_roundtrip — exercises encrypt→decrypt full path | Full | +| C04 | binary_split.py (decrypt_archive) | test_unlock_with_corrupt_archive — exercises decrypt path (error case) | Partial — no happy-path unlock test | +| C09 | api_client.pyx (cdn upload check) | test_upload_resource, test_upload_download_roundtrip — upload happy path | Full | +| C10 | api_client.pyx (upload_file propagation) | test_upload_resource — upload to API path | Full | +| C01 | main.py (singleton) | All endpoint tests exercise get_api_client() | Full (sequential only) | +| C02 | main.py (unlock state) | test_unlock_status_idle, test_unlock_missing_archive, test_unlock_concurrent_returns_current_state | Full | +| C05 | constants.pyx (log path) | Indirect — service starts and logs | Sufficient | +| C06 | main.py (os.remove log) | test_unlock_with_corrupt_archive — triggers _run_unlock | Partial | +| C07 | api_client.pyx (dead methods) | N/A — deletion only, no behavior change | N/A | +| C08 | constants.pyx (dead constants) | N/A — deletion only, no behavior change | N/A | + +## Assessment + +All public API endpoints are covered by blackbox tests.
