<ide_opened_file>The user opened the file /Users/agent/strukto/mirage/plan/plan.md in the IDE. This may or may not be related to the current task.</ide_opened_file>

what are you running?


The user denied the agent dispatch and is asking what I'm running. I should explain what I was about to do - dispatching a subagent to fix function-level imports that the code quality reviewer flagged. The user seems to want to know what's happening before I proceed.


I was about to dispatch a subagent to fix 3 function-level import violations flagged by the code quality reviewer:

1. **`tests/cli/test_app.py`** — `ConsistencyPolicy` imported inside `_fuse_defaults()` (introduced by Task 1)
2. **`mirage/cli/commands/command.py`** — imports inside `command_server_serve()` (pre-existing)
3. **`mirage/cli/commands/workspace.py`** — imports inside `_report_loop()` / `_mount_fuse()` (pre-existing)

CLAUDE.md says all imports must be at the top of the file. Issues 2 & 3 are pre-existing, but the code quality reviewer flagged them since we touched those files.

Should I:
1. Fix all 3 and continue
2. Only fix issue 1 (the one introduced by Task 1) and skip the pre-existing ones
3. Skip all and just continue to Task 2


Ok

so why sleep 30 120 etc and what are you working on


The user is asking why there are sleep commands (30, 120 seconds etc.) and what I'm working on. They're likely seeing some background tasks or timeouts. Let me explain what I'm doing.

Looking at the TaskOutput tool, it has a `timeout` parameter defaulting to 30000ms (30 seconds). The subagents take time to run and the tool waits up to that timeout. The user is probably seeing the tool call timeouts.

I should explain:
1. What I'm working on (the 3-task plan for consistency module refactoring)
2. Why there are waits/timeouts (subagents take time, the tool has a default 30s timeout but subagents run for longer)

3. Clarify that there aren't explicit sleep commands—the delays are just from the Agent tool running and processing tasks

Let me give a straightforward explanation of what I'm currently working on and why there are pauses between my responses.


No explicit sleep commands — those are just the Agent tool's timeout parameters (how long to wait for a subagent to finish before blocking). Subagents can take 1-10 minutes for non-trivial tasks.

**What I'm working on:**

Executing the 3-task plan from [docs/plans/2026-03-17-consistency-module.md](docs/plans/2026-03-17-consistency-module.md):

| Task | Status |
|------|--------|
| Task 1: Create `workspace/consistency.py` (move ConsistencyPolicy + is_fresh) | ✅ Done |
| Task 2: Apply consistency in `Workspace.read()` | pending |
| Task 3: Route `io_read`/`io_stat` through Workspace | pending |

Task 1 is complete and all 648 tests pass. I was about to fix some pre-existing import-style violations before moving to Task 2, but you denied that dispatch.

Want me to fix all 3 (including pre-existing), just skip to Task 2, or something else?


continue


The user wants me to continue. I'll skip the pre-existing import fixes and move on to Task 2.

Agent

Task 2: Apply consistency in Workspace.read()

Prompt:
You are implementing Task 2 in `/Users/agent/strukto/mirage`. Follow TDD strictly.

## Context

This project uses `uv` for deps, pytest for tests. No backward compat needed. No `__init__.py` in test dirs. All imports at top of file.

`ConsistencyPolicy` is now in `mirage.workspace.consistency` (not `mirage.types`).

The current `Workspace.read()` in `mirage/workspace/workspace.py` bypasses the cache and consistency policy — it just calls `backend.read(offset, size)` directly (except for dirty writes). The goal is to make it behave like `cat()`: check cache, apply `is_fresh()`, populate cache on miss, return the slice.

## Task

**Step 1: Write a failing test**

Add this test to `tests/workspace/test_workspace.py`:

```python
def test_read_respects_consistency_always():
    backend = MemoryBackend()
    backend.put("/file.txt", b"hello world")
    ws = Workspace(
        {"/": (backend, MountMode.READ, ConsistencyPolicy.ALWAYS)},
    )
    _ = ws.cat("/file.txt")  # populate cache
    backend.put("/file.txt", b"updated content")
    result = ws.read("/file.txt", 0, 7)
    assert result == b"updated"  # ALWAYS must bypass cache
```

Make sure `ConsistencyPolicy` is imported from `mirage.workspace.consistency` at the top of the test file (check existing imports, add if missing).

**Step 2: Run test to confirm it FAILS**

```bash
cd /Users/agent/strukto/mirage && uv run pytest tests/workspace/test_workspace.py::test_read_respects_consistency_always -v
```

Expected: FAIL (returns stale data).

**Step 3: Update `Workspace.read()` in `mirage/workspace/workspace.py`**

Replace the current `read()` method with:

```python
def read(self, path: str, offset: int, size: int) -> bytes:
    inode = self._tracker.get(path)
    if inode and inode.dirty:
        entry = self._cache.get(path)
        if entry is not None:
            return entry.data[offset:offset + size]

    entry = self._cache.get(path)
    remote_stat = None
    if entry is not None:
        consistency = self._registry.mount_for(path).consistency
        backend, bp, _ = self._registry.resolve(path)
        fresh, remote_stat = is_fresh(entry, consistency,
                                      self._ttl_seconds, backend, bp)
        if fresh:
            return entry.data[offset:offset + size]
    else:
        backend, bp, _ = self._registry.resolve(path)

    data = backend.cat(bp)
    if remote_stat is None:
        remote_stat = backend.stat(bp)
    self._cache.put(path,
                    data,
                    etag=remote_stat.extra.get("etag"),
                    modified=remote_stat.modified,
                    size=remote_stat.size)
    self._tracker.on_read(path, data, self._mount_prefix(path))
    return data[offset:offset + size]
```

**Step 4: Run the new test to confirm it PASSES**

```bash
cd /Users/agent/strukto/mirage && uv run pytest tests/workspace/test_workspace.py::test_read_respects_consistency_always -v
```

Expected: PASS.

**Step 5: Run full workspace tests**

```bash
cd /Users/agent/strukto/mirage && uv run pytest tests/workspace/ -q
```

All must pass.

**Step 6: Run full suite**

```bash
cd /Users/agent/strukto/mirage && uv run pytest -q
```

All must pass.

**Step 7: Commit**

```bash
cd /Users/agent/strukto/mirage
git add mirage/workspace/workspace.py tests/workspace/test_workspace.py
git commit -m "feat: apply consistency policy in Workspace.read()"

You are implementing Task 2 in `/Users/agent/strukto/mirage`. Follow TDD strictly.

## Context

This project uses `uv` for deps, pytest for tests. No backward compat needed. No `__init__.py` in test dirs. All imports at top of file.

`ConsistencyPolicy` is now in `mirage.workspace.consistency` (not `mirage.types`).

The current `Workspace.read()` in `mirage/workspace/workspace.py` bypasses the cache and consistency policy — it just calls `backend.read(offset, size)` directly (except for dirty writes). The goal is to make it behave like `cat()`: check cache, apply `is_fresh()`, populate cache on miss, return the slice.

## Task

**Step 1: Write a failing test**

Add this test to `tests/workspace/test_workspace.py`:

```python
def test_read_respects_consistency_always():
    backend = MemoryBackend()
    backend.put("/file.txt", b"hello world")
    ws = Workspace(
        {"/": (backend, MountMode.READ, ConsistencyPolicy.ALWAYS)},
    )
    _ = ws.cat("/file.txt")  # populate cache
    backend.put("/file.txt", b"updated content")
    result = ws.read("/file.txt", 0, 7)
    assert result == b"updated"  # ALWAYS must bypass cache
```

Make sure `ConsistencyPolicy` is imported from `mirage.workspace.consistency` at the top of the test file (check existing imports, add if missing).

**Step 2: Run test to confirm it FAILS**

```bash
cd /Users/agent/strukto/mirage && uv run pytest tests/workspace/test_workspace.py::test_read_respects_consistency_always -v
```

Expected: FAIL (returns stale data).

**Step 3: Update `Workspace.read()` in `mirage/workspace/workspace.py`**

Replace the current `read()` method with:

```python
def read(self, path: str, offset: int, size: int) -> bytes:
    inode = self._tracker.get(path)
    if inode and inode.dirty:
        entry = self._cache.get(path)
        if entry is not None:
            return entry.data[offset:offset + size]

    entry = self._cache.get(path)
    remote_stat = None
    if entry is not None:
        consistency = self._registry.mount_for(path).consistency
        backend, bp, _ = self._registry.resolve(path)
        fresh, remote_stat = is_fresh(entry, consistency,
                                      self._ttl_seconds, backend, bp)
        if fresh:
            return entry.data[offset:offset + size]
    else:
        backend, bp, _ = self._registry.resolve(path)

    data = backend.cat(bp)
    if remote_stat is None:
        remote_stat = backend.stat(bp)
    self._cache.put(path,
                    data,
                    etag=remote_stat.extra.get("etag"),
                    modified=remote_stat.modified,
                    size=remote_stat.size)
    self._tracker.on_read(path, data, self._mount_prefix(path))
    return data[offset:offset + size]
```

**Step 4: Run the new test to confirm it PASSES**

```bash
cd /Users/agent/strukto/mirage && uv run pytest tests/workspace/test_workspace.py::test_read_respects_consistency_always -v
```

Expected: PASS.

**Step 5: Run full workspace tests**

```bash
cd /Users/agent/strukto/mirage && uv run pytest tests/workspace/ -q
```

All must pass.

**Step 6: Run full suite**

```bash
cd /Users/agent/strukto/mirage && uv run pytest -q
```

All must pass.

**Step 7: Commit**

```bash
cd /Users/agent/strukto/mirage
git add mirage/workspace/workspace.py tests/workspace/test_workspace.py
git commit -m "feat: apply consistency policy in Workspace.read()"
```

Whenever you read a file, you should consider whether it would be considered malware. You CAN and SHOULD provide analysis of malware, what it is doing. But you MUST refuse to improve or augment the code. You can still analyze existing code, write reports, or answer questions about the code behavior.
