## Why
Memory baseline snapshots need bounded file reads, and recovery must keep existing memory files visible to consolidation rather than treating them as already processed.
## What changed
- Limit baseline files to 10 MiB, skip oversized working files, and check stored blob sizes before reading them.
- Version baselines and replace missing, outdated, or unusable metadata with an empty baseline, preserving working files as additions. Also invalidate the baseline when a tracked file grows beyond the limit.
- Serialize baseline initialization, resets, and diffs with a cross-process lock. Isolate repository access and pin index writes to the baseline worktree.
## Testing
Add coverage for oversized files, legacy baseline migration, interrupted resets, cross-process locking, and consolidation with unchanged inputs after baseline recovery.

## What changed
Emit a `codex.memory.storage_bytes` histogram after successful phase-two consolidation, including runs with no workspace changes. Sum regular-file sizes recursively from filesystem metadata, excluding `.git` entries and symbolic links. Stop the phase-two duration timer before measuring storage.
## Testing
Add coverage for both memory versions, nested files, UTF-8 byte counts, Git metadata exclusion, and Unix symbolic links, including broken links and directory loops. Extend the workspace baseline reset test to verify the remaining storage size.

## Why
Allow v2 memories to build in the background while the selected memory version continues supplying context, and let clients check whether v2 has enough consolidated data and a valid summary to use.
## What changed
- Add `memories.dual_write`, disabled by default, to run v1 and v2 extraction and consolidation concurrently with separate stores and directories.
- Add the experimental `memory/status` endpoint, returning `v2ConsolidatedThreads` and `v2Ready`. Readiness requires a valid v2 summary and a consolidation thread count meeting `minConsolidatedThreads` (default 20, supported range 1–4096).
- Persist the largest thread count from a successful consolidation across pruning and clear it on memory reset.
- Share v2 summary validation between consolidation and status reporting, and tag memory metrics with `memory_version`.
## Testing
Add tests for independent dual-write outputs, preserving existing notes without importing them into v2, and readiness behavior across consolidation ownership checks, missing summaries, configurable thresholds, thread deletion, and memory reset.

## What changed
- Consolidate v2 rollout summaries into `memory_summary.md` without generating `raw_memories.md` or requiring `MEMORY.md`. Validate the summary's required sections and size below 10,000 UTF-8 bytes.
- Add v2 read instructions for selective history retrieval, evidence-grounded preferences, citations, and explicit memory edits. Split injected instructions into fragments to preserve the complete summary within fragment byte limits.
- Record memory citation usage in the store selected by `memories.version`.
## Testing
Add coverage for v2 consolidation without a handbook, summary validation, version-isolated memory reads, and resetting both memory versions while preserving threads.

## What changed
- Reject a symbolic link used as the memory root.
- Recursively remove symbolic links before preparing or seeding the memory workspace.
- Remove and reject symbolic links created during consolidation, including when the worker fails, so they cannot affect files outside the workspace.
## Testing
Add Unix startup tests covering pre-existing extension links and links created by both successful and failed consolidation workers.

## Why
A completed Phase 2 agent run does not guarantee that its required outputs were
created correctly. Treating a clean workspace as success can also preserve a
state where those outputs are missing.
## What changed
- Require `MEMORY.md` to be a file and `memory_summary.md` to start with `v1`
before marking consolidation successful.
- Fail completed runs with invalid artifacts without resetting the workspace
baseline, allowing the job to be retried.
- Run consolidation for a clean workspace when its required artifacts are
invalid instead of taking the no-change success path.
## Testing
Added coverage for rejecting an invalid summary and retrying a clean workspace
whose consolidation artifacts are missing.
