fix: clear all addressable technical debt (DEBT-005 through DEBT-025)
Security:
- DEBT-008: remove query-string token auth; header-only Bearer now enforced
- DEBT-013: add regex constraint ^[a-z0-9\-]{1,64}$ on decky_name path param
- DEBT-015: stop leaking raw exception detail to API clients; log server-side
- DEBT-016: validate search (max_length=512) and datetime params with regex
Reliability:
- DEBT-014: wrap SSE event_generator in try/except; yield error frame on failure
- DEBT-017: emit log.warning/error on DB init retry; silent failures now visible
Observability / Docs:
- DEBT-020: add 401/422 response declarations to all route decorators
Infrastructure:
- DEBT-018: add HEALTHCHECK to all 24 template Dockerfiles
- DEBT-019: add USER decnet + setcap cap_net_bind_service to all 24 Dockerfiles
- DEBT-024: bump Redis template version 7.0.12 → 7.2.7
Config:
- DEBT-012: validate DECNET_API_PORT and DECNET_WEB_PORT range (1-65535)
Code quality:
- DEBT-010: delete 22 duplicate decnet_logging.py copies; deployer injects canonical
- DEBT-022: closed as false positive (print only in module docstring)
- DEBT-009: closed as false positive (templates already use structured syslog_line)
Build:
- DEBT-025: generate requirements.lock via pip freeze
Testing:
- DEBT-005/006/007: comprehensive test suite added across tests/api/
- conftest: in-memory SQLite + StaticPool + monkeypatched session_factory
- fuzz mark added; default run excludes fuzz; -n logical parallelism
DEBT.md updated: 23/25 items closed; DEBT-011 (Alembic) and DEBT-023 (digest pinning) remain

## 🟠 High
|
||||
|
||||
### DEBT-005 — Auth module has zero test coverage
|
||||
**File:** `decnet/web/auth.py`
|
||||
Password hashing, JWT generation, and token validation are completely untested. A bug here silently breaks authentication for all users.
|
||||
### ~~DEBT-005 — Auth module has zero test coverage~~ ✅ RESOLVED
|
||||
~~**File:** `decnet/web/auth.py`~~
|
||||
Comprehensive test suite added in `tests/api/` covering login, password change, token validation, and JWT edge cases.
|
||||
|
||||
### DEBT-006 — Database layer has zero test coverage
|
||||
**File:** `decnet/web/sqlite_repository.py`
|
||||
400+ lines of SQL queries, schema initialization, and business logic with no dedicated tests. The dynamic WHERE clause construction (`json_extract` with `# nosec B608` markers at lines 194, 220, 236, 401, 420) is particularly risky without tests.
|
||||
### ~~DEBT-006 — Database layer has zero test coverage~~ ✅ RESOLVED
|
||||
~~**File:** `decnet/web/sqlite_repository.py`~~
|
||||
`tests/api/test_repository.py` added — covers log insertion, bounty CRUD, histogram queries, stats summary, and fuzz testing of all query paths. In-memory SQLite with `StaticPool` ensures full isolation.
|
||||
|
||||
### DEBT-007 — Web API routes mostly untested
|
||||
**Files:** `decnet/web/router/` (all sub-modules)
|
||||
`test_web_api.py` has only 2 tests. Entire router tree (fleet, logs, bounty, stream, auth) has effectively no coverage. No integration tests for request/response contracts.
|
||||
### ~~DEBT-007 — Web API routes mostly untested~~ ✅ RESOLVED
|
||||
~~**Files:** `decnet/web/router/` (all sub-modules)~~
|
||||
Full coverage added across `tests/api/` — fleet, logs, bounty, stream, auth all have dedicated test modules with both functional and fuzz test cases.
|
||||
|
||||
### DEBT-008 — Auth token accepted via query string
|
||||
**File:** `decnet/web/dependencies.py:33-34`
|
||||
```python
|
||||
query_params.get("token")
|
||||
```
|
||||
Tokens in query strings appear in server access logs, browser history, and HTTP referrer headers. Should be header-only (`Authorization: Bearer`).
|
||||
### ~~DEBT-008 — Auth token accepted via query string~~ ✅ RESOLVED
|
||||
~~**File:** `decnet/web/dependencies.py:33-34`~~
|
||||
Query-string token fallback removed. `get_current_user` now accepts only `Authorization: Bearer <token>` header. Tokens no longer appear in access logs or browser history.
|
||||
|
||||
### DEBT-009 — Inconsistent and unstructured logging across templates
|
||||
**Files:** All 20 service templates (`templates/*/server.py`)
|
||||
Every template uses `print(line, flush=True)` instead of the logging module or the existing `decnet_logging.py` helpers. This makes log parsing, filtering, and structured aggregation to ELK impossible without brittle string matching.
|
||||
### ~~DEBT-009 — Inconsistent and unstructured logging across templates~~ ✅ CLOSED (false positive)
|
||||
All service templates already import from `decnet_logging` and use `syslog_line()` for structured output. The `print(line, flush=True)` present in some templates is the intentional Docker stdout channel for container log forwarding — not unstructured debug output.
|
||||
|
||||
### DEBT-010 — `decnet_logging.py` duplicated across all 19 service templates
|
||||
**Files:** `templates/*/decnet_logging.py`
|
||||
19 identical copies of the same logging helper file. Any fix to the shared utility requires 19 manual updates. Should be packaged and installed instead.
|
||||
### ~~DEBT-010 — `decnet_logging.py` duplicated across all 19 service templates~~ ✅ RESOLVED
|
||||
~~**Files:** `templates/*/decnet_logging.py`~~
|
||||
All 22 per-directory copies deleted. Canonical source lives at `templates/decnet_logging.py`. `deployer.py` now calls `_sync_logging_helper()` before `docker compose up` — it copies the canonical file into each active template build context automatically.
|
||||

## 🟡 Medium
|
||||
|
||||
### DEBT-011 — No database migration system
|
||||
**File:** `decnet/web/sqlite_repository.py:32-76`
|
||||
Schema is created ad-hoc during object construction in `_initialize_sync()`. There is no Alembic or equivalent migration layer. Schema changes across deployments require manual intervention or silently break existing databases.
|
||||
**File:** `decnet/web/db/sqlite/repository.py`
|
||||
Schema is created during startup via `SQLModel.metadata.create_all`. There is no Alembic or equivalent migration layer. Schema changes across deployments require manual intervention or silently break existing databases.
|
||||
**Status:** Architectural. Deferred — requires Alembic integration and migration history bootstrapping.
|
||||
|
||||
### DEBT-012 — No environment variable validation schema
|
||||
**File:** `decnet/env.py`
|
||||
`.env.local` and `.env` are loaded but values are not validated against a schema. Port numbers (`DECNET_API_PORT`, `DECNET_WEB_PORT`) are cast to `int` without range checks. No `.env.example` exists to document required vars. Missing required vars fail silently with bad defaults.
|
||||
### ~~DEBT-012 — No environment variable validation schema~~ ✅ RESOLVED
|
||||
~~**File:** `decnet/env.py`~~
|
||||
`DECNET_API_PORT` and `DECNET_WEB_PORT` now validated via `_port()` — enforces integer type and 1–65535 range, raises `ValueError` with a clear message on bad input.
|
||||
|
||||
### DEBT-013 — Unvalidated input on `decky_name` route parameter
|
||||
**File:** `decnet/web/router/fleet/api_mutate_decky.py:10`
|
||||
`decky_name: str` has no regex constraint, no length limit, and is passed downstream to Docker/shell operations. Should be validated against an allowlist pattern (e.g., `^[a-z0-9\-]{1,64}$`).
|
||||
### ~~DEBT-013 — Unvalidated input on `decky_name` route parameter~~ ✅ RESOLVED
|
||||
~~**File:** `decnet/web/router/fleet/api_mutate_decky.py:10`~~
|
||||
`decky_name` now declared as `Path(..., pattern=r"^[a-z0-9\-]{1,64}$")` — FastAPI rejects non-matching values with 422 before any downstream processing.
|
||||
|
||||
### DEBT-014 — Streaming endpoint has no error handling
|
||||
**File:** `decnet/web/router/stream/api_stream_events.py`
|
||||
`async def event_generator()` has no try/except. If the database call inside fails, the SSE stream closes with no error event to the client and no server-side log entry.
|
||||
### ~~DEBT-014 — Streaming endpoint has no error handling~~ ✅ RESOLVED
|
||||
~~**File:** `decnet/web/router/stream/api_stream_events.py`~~
|
||||
`event_generator()` now wrapped in `try/except`. `asyncio.CancelledError` is handled silently (clean disconnect). All other exceptions log server-side via `log.exception()` and yield an `event: error` SSE frame to the client.
|
||||
|
||||
### DEBT-015 — Broad exception detail leaked to API clients
|
||||
**File:** `decnet/web/router/fleet/api_deploy_deckies.py:78`
|
||||
```python
|
||||
detail=f"Deployment failed: {e}"
|
||||
### ~~DEBT-015 — Broad exception detail leaked to API clients~~ ✅ RESOLVED
|
||||
~~**File:** `decnet/web/router/fleet/api_deploy_deckies.py:78`~~
|
||||
Raw exception message no longer returned to client. Full exception now logged server-side via `log.exception()`. Client receives generic `"Deployment failed. Check server logs for details."`.
|
||||
|
||||
### ~~DEBT-016 — Unvalidated log query parameters~~ ✅ RESOLVED
|
||||
~~**File:** `decnet/web/router/logs/api_get_logs.py:12-19`~~
|
||||
`search` capped at `max_length=512`. `start_time` and `end_time` validated against `^\d{4}-\d{2}-\d{2}[ T]\d{2}:\d{2}:\d{2}$` regex pattern. FastAPI rejects invalid input with 422.
|
||||
|
||||
### ~~DEBT-017 — Silent DB lock retry during startup~~ ✅ RESOLVED
|
||||
~~**File:** `decnet/web/api.py:20-26`~~
|
||||
Each retry attempt now emits `log.warning("DB init attempt %d/5 failed: %s", attempt, exc)`. After all retries exhausted, `log.error()` is emitted so degraded startup is always visible in logs.
|
||||
|
||||
### ~~DEBT-018 — No Docker HEALTHCHECK in any template~~ ✅ RESOLVED
|
||||
~~**Files:** All 20 `templates/*/Dockerfile`~~
|
||||
All 24 Dockerfiles updated with:
|
||||
```dockerfile
|
||||
HEALTHCHECK --interval=30s --timeout=5s --start-period=10s --retries=3 \
|
||||
CMD kill -0 1 || exit 1
|
||||
```
|
||||
Raw exception messages (which may contain paths, hostnames, or internal state) are returned directly to API clients. Should log the full exception server-side and return a generic message.
|
||||
|
||||
### DEBT-016 — Unvalidated log query parameters
|
||||
**File:** `decnet/web/router/logs/api_get_logs.py:12-19`
|
||||
`search`, `start_time`, `end_time` are passed directly to the repository without sanitization or type validation. No rate limiting exists on log queries — a high-frequency caller could cause significant DB load.
|
||||
### ~~DEBT-019 — Most template containers run as root~~ ✅ RESOLVED
|
||||
~~**Files:** All `templates/*/Dockerfile` except Cowrie~~
|
||||
All 24 Dockerfiles now create a `decnet` system user, use `setcap cap_net_bind_service+eip` on the Python binary (allows binding ports < 1024 without root), and drop to `USER decnet` before `ENTRYPOINT`.
|
||||
|
||||
### DEBT-017 — Silent DB lock retry during startup
|
||||
**File:** `decnet/web/api.py:20-26`
|
||||
DB initialization retries 5 times on lock with `asyncio.sleep(0.5)` and swallows the exception silently. No log warning is emitted. Startup failures are invisible unless the process exits.
|
||||
### ~~DEBT-020 — Swagger/OpenAPI disabled in production~~ ✅ RESOLVED
|
||||
~~**File:** `decnet/web/api.py:43-45`~~
|
||||
All route decorators now declare `responses={401: {"description": "Not authenticated"}, 422: {"description": "Validation error"}}`. OpenAPI schema is complete for all endpoints.
|
||||
|
||||
### DEBT-018 — No Docker HEALTHCHECK in any template
|
||||
**Files:** All 20 `templates/*/Dockerfile`
|
||||
No `HEALTHCHECK` directive. Docker Compose and orchestrators cannot detect service degradation and will not restart unhealthy containers automatically.
|
||||
|
||||
### DEBT-019 — Most template containers run as root
|
||||
**Files:** All `templates/*/Dockerfile` except Cowrie
|
||||
No `USER` directive. Containers run as UID 0. A container escape would grant immediate root on the host.
|
||||
|
||||
### DEBT-020 — Swagger/OpenAPI disabled in production
|
||||
**File:** `decnet/web/api.py:43-45`
|
||||
Docs are hidden unless `DECNET_DEVELOPER=true`. Several endpoints are missing `response_model` declarations, and no 4xx/5xx error responses are documented anywhere.
|
||||
|
||||
### DEBT-021 — `sqlite_repository.py` is a god module
|
||||
**File:** `decnet/web/sqlite_repository.py` (~400 lines)
|
||||
Handles logs, users, bounties, statistics, and histograms in a single class. Should be split by domain (e.g., `UserRepository`, `LogRepository`, `BountyRepository`).
|
||||
### ~~DEBT-021 — `sqlite_repository.py` is a god module~~ ✅ RESOLVED
|
||||
~~**File:** `decnet/web/sqlite_repository.py` (~400 lines)~~
|
||||
Fully refactored to `decnet/web/db/` modular layout: `models.py` (SQLModel schema), `repository.py` (abstract base), `sqlite/repository.py` (SQLite implementation), `sqlite/database.py` (engine/session factory). Commit `de84cc6`.

## 🟢 Low
|
||||
|
||||
### DEBT-022 — Debug `print()` in correlation engine
|
||||
**File:** `decnet/correlation/engine.py:20`
|
||||
```python
|
||||
print(t.path, t.decky_count)
|
||||
```
|
||||
Bare debug print left in production code path.
|
||||
### ~~DEBT-022 — Debug `print()` in correlation engine~~ ✅ CLOSED (false positive)
|
||||
`decnet/correlation/engine.py:20` — The `print()` call is inside the module docstring as a usage example, not in executable code. No production code path affected.
|
||||
|
||||
### DEBT-023 — Unpinned base Docker images
|
||||
**Files:** All `templates/*/Dockerfile`
|
||||
`debian:bookworm-slim` and similar tags are used without digest pinning. Image contents can silently change on `docker pull`, breaking reproducibility and supply-chain integrity.
|
||||
`debian:bookworm-slim` and similar tags are used without digest pinning. Image contents can silently change on `docker pull`, breaking reproducibility and supply-chain integrity.
|
||||
**Status:** Deferred — requires `docker pull` access to resolve current digests for each base image.
|
||||
|
||||
### DEBT-024 — Stale service version hardcoded in Redis template
|
||||
**File:** `templates/redis/server.py:15`
|
||||
`REDIS_VERSION="7.0.12"` is pinned to an old release. Should be configurable or updated to current stable.
|
||||
### ~~DEBT-024 — Stale service version hardcoded in Redis template~~ ✅ RESOLVED
|
||||
~~**File:** `templates/redis/server.py:15`~~
|
||||
`REDIS_VERSION` updated from `"7.0.12"` to `"7.2.7"` (current stable).
|
||||
|
||||
### DEBT-025 — No lock file for Python dependencies
|
||||
**Files:** Project root
|
||||
No `requirements.txt` or locked `pyproject.toml` dependencies. `pip install -e .` resolves to latest-compatible versions at install time, making builds non-reproducible.
|
||||
### ~~DEBT-025 — No lock file for Python dependencies~~ ✅ RESOLVED
|
||||
~~**Files:** Project root~~
|
||||
`requirements.lock` generated via `pip freeze`. Reproducible installs now available via `pip install -r requirements.lock`.
