-## Testing
-
-- `make test-dev` - Use this when making iterative changes. Runs `go test` and `staticcheck`. Fix any static checking errors.
-- `make test-all` - runs at the end before completing work. Includes long running concurrency tests.
-
 ## Workflow Tasks
 
-### Plan Improvements
+- when summarizing changes only include details that require further action
+- just say "Done." when there is no further action
+- use `gh` to create PRs and load issues
+- do not mention "created by claude" in commit messages
 
-Work plans are located in ai-plans/. Plans written by the user may be incomplete, contain inconsistencies or errors.
+## Testing
 
-When the user asks to improve a plan follow these guidelines for expanding and improving it.
+- Follow test naming conventions like `TestProxyManager_<test name>`, `TestProcessGroup_<test name>`, etc.
+- Use `go test -v -run <name pattern for new tests>` to run any new tests you've written.
+- Use `make test-dev` after running new tests for a quick over all test run. This runs `go test` and `staticcheck`. Fix any static checking errors. Use this only when changes are made to any code under the `proxy/` directory
+- Use `make test-all` before completing work. This includes long running concurrency tests.
 
-- Identify any inconsistencies.
-- Expand plans out to be detailed specification of requirements and changes to be made.
-- Plans should have at least these sections:
-  - Title - very short, describes changes
-  - Overview: A more detailed summary of goal and outcomes desired
-  - Design Requirements: Detailed descriptions of what needs to be done
-  - Testing Plan: Tests to be implemented
-  - Checklist: A detailed list of changes to be made
+### Commit message example format:
 
-Look for "plan expansion" as explicit instructions to improve a plan.
+```
+proxy: add new feature
 
-### Implementation of plans
+Add new feature that implements functionality X and Y.
 
-When the user says "paint it", respond with "commencing automated assembly". Then implement the changes as described by the plan. Update the checklist as you complete items.
+- key change 1
+- key change 2
+- key change 3
 
-## General Rules
+fixes #123
+```
 
-- when summarizing changes only include details that require further action (action items)
-- when there are no action items, just say "Done."
+## Code Reviews
+
+- use three levels High, Medium, Low severity
+- label each discovered issue with a label like H1, M2, L3 respectively
+- High severity are must fix issues:
+
+  - security issues
+
+- Medium are recommended improvements

+# Replace ring.Ring with Efficient Circular Byte Buffer
+
+## Overview
+
+Replace the inefficient `container/ring.Ring` implementation in `logMonitor.go` with a simple circular byte buffer that uses a single contiguous `[]byte` slice. This eliminates per-write allocations, improves cache locality, and correctly implements a 10KB buffer.
+
+## Current Issues
+
+1. `ring.New(10 * 1024)` creates 10,240 ring **elements**, not 10KB of storage
+2. Every `Write()` call allocates a new `[]byte` slice inside the lock
+3. `GetHistory()` iterates all 10,240 elements and appends repeatedly (geometric reallocs)
+4. Linked list structure has poor cache locality and pointer overhead
+
+## Design Requirements
+
+### New CircularBuffer Type
+
+Create a simple circular byte buffer with:
+- Single pre-allocated `[]byte` of fixed capacity (10KB)
+- `head` and `size` integers to track write position and data length
+- No per-write allocations
+
+### API Requirements
+
+The new buffer must support:
+1. **Write(p []byte)** - Append bytes, overwriting oldest data when full
+2. **GetHistory() []byte** - Return all buffered data in correct order (oldest to newest)
+
+### Implementation Details
+
+```go
+type circularBuffer struct {
+    data []byte  // pre-allocated capacity
+    head int     // next write position
+    size int     // current number of bytes stored (0 to cap)
+}
+```
+
+**Write logic:**
+- If `len(p) >= capacity`: just keep the last `capacity` bytes
+- Otherwise: write bytes at `head`, wrapping around if needed
+- Update `head` and `size` accordingly
+- Data is copied into the internal buffer (not stored by reference)
+
+**GetHistory logic:**
+- Calculate start position: `(head - size + cap) % cap`
+- If not wrapped: single slice copy
+- If wrapped: two copies (end of buffer + beginning)
+- Returns a **new slice** (copy), not a view into internal buffer
+
+### Immutability Guarantees (must preserve)
+
+Per existing tests:
+1. Modifying input `[]byte` after `Write()` must not affect stored data
+2. `GetHistory()` returns independent copy - modifications don't affect buffer
+
+## Files to Modify
+
+- `proxy/logMonitor.go` - Replace `buffer *ring.Ring` with new circular buffer
+
+## Testing Plan
+
+Existing tests in `logMonitor_test.go` should continue to pass:
+- `TestLogMonitor` - Basic write/read and subscriber notification
+- `TestWrite_ImmutableBuffer` - Verify writes don't affect returned history
+- `TestWrite_LogTimeFormat` - Timestamp formatting
+
+Add new tests:
+- Test buffer wrap-around behavior
+- Test large writes that exceed buffer capacity
+- Test exact capacity boundary conditions
+
+## Checklist
+
+- [ ] Create `circularBuffer` struct in `logMonitor.go`
+- [ ] Implement `Write()` method for circular buffer
+- [ ] Implement `GetHistory()` method for circular buffer
+- [ ] Update `LogMonitor` struct to use new buffer
+- [ ] Update `NewLogMonitorWriter()` to initialize new buffer
+- [ ] Update `LogMonitor.Write()` to use new buffer
+- [ ] Update `LogMonitor.GetHistory()` to use new buffer
+- [ ] Remove `"container/ring"` import
+- [ ] Run `make test-dev` to verify existing tests pass
+- [ ] Add wrap-around test case
+- [ ] Run `make test-all` for final validation

+## Container Security
+
+For convenience, the default container images use the **root** user within the container. This permits simplified access to host resources including volume mounts and hardware devices under `/dev/dri` (_for Vulkan support_). But this can widen the attack surface to privilege escalation exploits.
+
+Alternative images, tagged as `non-root`, are also available. For example, `llama-swap:cpu-non-root` uses the unprivileged **app** user by default. Depending on deployment requirements, additional configuration may be necessary to ensure that the container retains access to required hosts resources. This might entail customizing host filesystem permissions/ownership appropriately or injecting host group membership into the container.
+
+Docker offers a [system-wide option enabling user namespace remapping](https://docs.docker.com/engine/security/userns-remap/) to accommodate situations were a **root** container user is required but also mentions that _"The best way to prevent privilege-escalation attacks from within a container is to configure your container's applications to run as unprivileged users."_ Podman offers similar capability, per-container, to [set UID/GID mapping in a new user namespace](https://docs.podman.io/en/latest/markdown/podman-run.1.html#set-uid-gid-mapping-in-a-new-user-namespace).
+
+The Large Language Model (_LLM/AI_) ecosystem is rapidly evolving and [serious security vulnerabilities have surfaced in the past](https://huggingface.co/docs/hub/security-pickle). These alternative _non-root_ images could reduce the impact of future unknown problems. However, proper planning and configuration is recommended to utilize them.
