feat(kdo): implement H2-R2 event-derived model history - #49
Merged
Conversation
📝 WalkthroughWalkthroughThe runtime now derives bounded model-visible history from session events. It validates canonical history records, serializes session execution and event emission, supports anchored recovery and tool history, and adds unit, concurrency, integration, and evidence-ledger coverage. ChangesModel-visible history runtime
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to The PR changes later model-visible history to be rebuilt from committed session events. Two failure paths still affect merge readiness: an authority-bearing tool can be retried without an explicit attempted or unknown outcome in history, and sink failures can leave partial or duplicate sequence records that break reconstruction. Normal checks pass, but these bounded correctness and security risks need explicit owner acceptance or fixes before merge. Sequence Diagram(s)sequenceDiagram

Finding
The aggregate-bounds fix is correct from static inspection. The loop constructs the assistant and all tool-result records, validates their combined message-count and content bounds, and only then emits the first I found no other actionable issue in the requested scope. The protected authority paths remain unchanged. The evidence ledger remains absent. I used the existing H2-R1 repository guidance that 🧠 Learnings usedYou are interacting with an AI system. |

Node.js fs promises appendFile partial write rejects after data persisted atomicity documentation
💡 Result:
Node.js provides no guarantees regarding the atomicity of fs.promises.appendFile operations [1][2]. Because appendFile (and writeFile) does not implement atomic file locking or transactional integrity at the library level, a process interruption—such as a crash or system failure—occurring mid-write can result in a partially written or corrupted file [3][4]. Key considerations regarding atomicity and partial writes: 1. Lack of Built-in Atomicity: The Node.js documentation does not claim that fs.promises.appendFile is atomic [1][5]. It is implemented as a wrapper that performs file I/O operations (effectively similar to a write call) [6][7][8]. If the data being appended is large or the system fails during the write, there is a risk that only a portion of the data is persisted to disk [3][4]. 2. Concurrent Write Risks: When multiple independent operations call fs.promises.appendFile on the same file without proper serialization (e.g., awaiting each promise or using a dedicated stream), their writes can interleave or overwrite each other [6][4]. Node.js does not manage internal file locking to prevent these race conditions [4]. 3. Recommended Patterns for Data Integrity: - For critical data or configurations: Use the write-to-temporary-file-then-rename pattern [3]. Write the new content to a temporary file in the same directory (to ensure it is on the same filesystem), then use fs.promises.rename to atomically replace the target file [3]. This ensures that readers only ever see the old complete file or the new complete file, never a partial state [3]. - For logs or continuous data: Use fs.createWriteStream. A persistent stream keeps the file descriptor open, reducing the overhead of repeated open/close operations associated with individual appendFile calls, and provides better handling for sequential data flow [1][3]. If you are performing multiple append operations, ensure you await each promise sequentially if the order and integrity of the individual chunks are required, as concurrent execution of these promises can lead to unpredictable file contents [4].

Make EventSink.append atomic or idempotent across failures. If append persists an event and then rejects, RuntimeSession.emit retries the same sequence with a new eventId. The sink can then contain duplicate sequence numbers, which breaks later reconstruction.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Eviction past an in-flight run cursor raises an unclassified RangeError.
loop.ts captures runStartSequence once and then calls eventsSnapshot(runStartSequence) for the rest of the run. If a single run emits more than 4096 events, journalEvictedThroughSequence moves past that cursor. Every later snapshot call then throws RangeError. That error is not an AgentLoopStop, so it propagates out of BoundedAgentLoop.run instead of returning a stop result with a reason.
The behavior is fail-closed, which matches the PR intent. Consider making the exhausted-window case a classified stop reason, so callers can distinguish window exhaustion from cursor misuse.

Derive the content-overflow fixture from the limits instead of magic numbers.
The test relies on three unrelated constants agreeing: reservedHeadroom of 2000 bytes, two 1500-character tool inputs, and the default maxToolResultChars. Each tool message is about 1514 bytes only if maxToolResultChars does not truncate it. If the default maxToolResultChars drops below about 1500, the two tool messages total at most 2000 bytes, the strict > comparison in assertHistoryBatchAppendable no longer trips, and this test fails or stops testing the content branch.
Compute the tool payload size from the limit, or assert the precondition explicitly.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Assert nested record immutability.
The test checks that input is frozen, but it does not check input.nested. This test passes if nested record values remain mutable because it mutates only the independent projected copy. Assert that frozenInput.nested is frozen before mutating the projection.
Proposed test addition
const frozenInput = record.message.toolCalls?.[0]?.input as Record<string, unknown>
assert.equal(Object.isFrozen(frozenInput), true)
+ assert.equal(Object.isFrozen(frozenInput.nested), true)
assert.equal(Object.prototype.hasOwnProperty.call(frozenInput, "__proto__"), true)📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
