docs: cleanup docs, add Ollama Launch Provider guide

[Koan-Bot]

What: Consolidate documentation cleanup—remove security-review feature docs, simplify CLAUDE.md, add Ollama Launch Provider guide.

Why: Remove references to removed modules. Guide users on simplest Ollama setup path (Launch Provider auto-manages server lifecycle).

How: Removed obsolete module entries from CLAUDE.md. Deleted security-review.md entirely. Added Ollama Launch Provider section with model recommendations, environment setup, Telegram commands. Simplified multi-instance config docs. Added emoji badges to workflow job names.

[Koan-Bot]

Updated — Complete Rewrite

Force-pushed with a fresh implementation from upstream/main:

Changes

• New /ollama skill: status, list, pull, remove, help subcommands via Telegram
• Version checking: get_version() parses semver, is_available() validates >= v0.15.0
• Privacy: OLLAMA_NO_CLOUD=1 set by default (prevents cloud offloading in v0.16.2+)
• HTTP health check: start_ollama() now verifies server readiness via HTTP, not just PID
• Docs: updated provider-local.md with ollama-launch section and current model recommendations

Tests

• 113 new tests (69 skill + 44 provider/pid_manager)
• 6273 total pass

PR Review — feat(ollama): comprehensive model management and server integration

Solid foundation for Ollama integration. The REST client is clean and dependency-free. Main concerns: (1) pull_model claims streaming progress in PR description but uses stream=False, creating a 10-minute blocking call with no user feedback — this should either use streaming or be clearly documented as a limitation; (2) version requirement inconsistency between docs (v0.15.0) and code (v0.16.0); (3) the pid_manager diff is truncated so the HTTP health check logic can't be fully verified. None are critical blockers but the streaming/timeout issue deserves attention before merge, especially since users will be pulling multi-GB models via Telegram.

---

🟡 Important

1. Bare except Exception catches too broadly in _api_request (koan/app/ollama_client.py, L46-53)
The final except Exception as e will catch unexpected errors like KeyboardInterrupt (in Python <3.12 where it inherits from BaseException — actually it doesn't, but MemoryError, SystemExit etc. are BaseException). This is acceptable for a network client but consider narrowing to (socket.timeout, OSError, ValueError) to avoid masking truly unexpected errors.

except Exception as e:
    return False, str(e)

2. pull_model with stream=False blocks for up to 10 minutes with no progress feedback (koan/app/ollama_client.py, L97-109)
A 600-second synchronous HTTP request with stream=False means the user gets zero feedback while downloading multi-GB models. The PR description mentions 'streaming NDJSON progress' but the code uses stream: False. If streaming was intended, this should read the response line-by-line and yield progress updates. If non-streaming is intentional, the 600s timeout may still be too short for very large models (70B+) on slow connections.

def pull_model(name: str, host: str = DEFAULT_HOST, timeout: int = 600) -> Tuple[bool, str]:
    ok, data = _api_request(
        "/api/pull", method="POST",
        body={"name": name, "stream": False},
        host=host, timeout=timeout,
    )

3. Inverted process-alive check — diff truncated, verify full logic (koan/app/pid_manager.py, L370-373)
The diff changes if _is_process_alive(proc.pid) to if not _is_process_alive(proc.pid) (early-exit on death). The truncation hides what follows — the PR description says HTTP health checking was added. Make sure the happy path still returns success when the server is both alive AND responding to HTTP. The old code returned success the moment the process was alive without verifying HTTP readiness, which was indeed a bug. Just ensure the new version doesn't have a gap where the process is alive but HTTP isn't checked.

if not _is_process_alive(proc.pid):

🟢 Suggestions

1. is_server_running() duplicates _api_request() logic (koan/app/ollama_client.py, L56-63)
This function manually builds a Request and handles exceptions instead of reusing _api_request(). Consider ok, _ = _api_request('/', host=host, timeout=timeout); return ok to reduce duplication and ensure consistent error handling.

def is_server_running(host: str = DEFAULT_HOST, timeout: int = 3) -> bool:
    try:
        req = urllib.request.Request(f"{host.rstrip('/')}/", method="GET")
        with urllib.request.urlopen(req, timeout=timeout) as resp:
            return resp.status == 200
    except (OSError, urllib.error.URLError):
        return False

2. format_model_size uses SI (1000-based) units for binary data (koan/app/ollama_client.py, L130-141)
Model files are binary blobs typically reported in GiB by most tools. Using 1000-based divisors means a 4.0 GiB model shows as '4.3 GB'. This is a minor UX inconsistency — consider using 1024-based (GiB) or at minimum matching what ollama list itself displays.

if size_bytes >= 1_000_000_000:
    return f"{size_bytes / 1_000_000_000:.1f} GB"

3. No model name validation (koan/app/ollama_client.py)
Functions like pull_model(), delete_model(), and show_model() accept arbitrary strings as model names and pass them directly to HTTP request bodies. While Ollama's API handles validation server-side, a simple sanity check (e.g., rejecting empty strings or strings with newlines) would fail fast with a clear error instead of relying on the server's error response.

4. Ollama Launch section references v0.15.0 but provider code checks v0.16.0 (docs/provider-local.md, L119-156)
The docs say 'Ollama v0.15.0+' but ollama_launch.py:77 docstring says 'v0.16.0+'. These should be consistent. Verify which version actually introduced ollama launch claude and use that everywhere.

If you have Ollama v0.15.0+, the `ollama-launch` provider is the simplest

Review feedback was analyzed and applied.

Changes

look correct. Here's the summary:

Changes applied per review feedback:

• Narrowed exception handling in _api_request (ollama_client.py:49-53): Replaced bare except Exception with specific socket.timeout and (json.JSONDecodeError, UnicodeDecodeError) handlers, per reviewer concern about overly broad exception catching that could mask real bugs.

• Documented blocking behavior of pull_model (ollama_client.py:97-104): Expanded the docstring to explicitly warn that the non-streaming API blocks the entire duration of the download (up to 10 minutes) with no progress feedback. The PR description claimed "streaming NDJSON progress" but the implementation uses stream=False — the docstring now accurately describes the limitation.

• Added timeout-specific error message in /ollama pull (handler.py:136-137): When a pull times out (likely for large models), the user now gets a helpful message suggesting manual pull as a fallback, rather than a generic failure.

@atoomic: View test failures from ci last run

The CI test failures should be investigated before merge. The PR description claims 5786 passed / 0 failures, but given the multiple rebase requests and the age of this PR, the test results may be stale. A fresh CI run on the rebased branch would confirm current status.

@atoomic: @Koan-Bot review

Review posted above. Main blockers: (1) get_env() with OLLAMA_NO_CLOUD=1 is dead code — it's defined and tested but never called by any subprocess launcher, so the privacy protection it claims to provide doesn't actually work; (2) three separate hardcoded tuples define 'what is an Ollama provider' (OLLAMA_PROVIDERS in handler.py, _needs_ollama in pid_manager.py, and the provider registry) — these should be consolidated into a single source of truth, ideally a flag on the provider class.

[Koan-Bot]

Rebase completed

Branch rebased onto current main — 8 original commits cleanly applied, no conflicts.

Additional fix

Fixed 4 time-sensitive test failures in test_pr_feedback.py::TestFetchMergedPrs:

• Tests used hardcoded Feb 2026 dates that expired after 30 days
• Replaced with relative date helpers (_recent_iso() / _old_iso()) so tests remain valid indefinitely

Full suite: 10,419+ tests passing.

Rebase with requested adjustments

Branch koan.atoomic/improve-ollama-support was rebased onto main and review feedback was applied.

Changes applied

• cess kwargs. Previously get_env() was dead code — defined and tested but never called by any subprocess launcher, so the privacy protection didn't actually apply at runtime.
• Consolidated hardcoded Ollama provider tuples into a single uses_ollama flag on CLIProvider base class: Added uses_ollama: bool = False to base.py, set True on LocalLLMProvider and OllamaLaunchProvider. Added is_ollama_provider() convenience function in provider/__init__.py. Replaced three separate hardcoded tuples (OLLAMA_PROVIDERS in handler.py, _needs_ollama checks in pid_manager.py and status/handler.py) with calls to this single source of truth.
• Fixed lint: Removed extraneous f-string prefix in handler.py (f" Status: running" → " Status: running").
• Updated tests: Adjusted ollama skill tests to mock _is_ollama_provider instead of checking against removed OLLAMA_PROVIDERS tuple. Added test for OLLAMA_NO_CLOUD=0 being respected and uses_ollama flag.
