ChangesInsight source ID cap
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The change limits provenance stored on newly created Insights, but existing Insights can still retain more than 20 source IDs, and the retained IDs may not reliably be the freshest because source ordering is unspecified. This can leave Insight attribution incomplete or inconsistent, so the PR needs explicit owner acceptance or fixes before merge. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Trim provenance on the reinforcement path.
The new cap applies only when the code creates an insight. If kv.get returns an existing insight with more than 20 source IDs, the reinforcement path writes those arrays back unchanged. Existing records can therefore continue to violate the bound.
Cap the arrays before kv.set, or add a migration for existing insights. Add a regression test for an oversized persisted insight.

iii engine state::list API ordering StateKV list records chronological order newest last
💡 Result:
The iii engine state::list API function returns a flat JSON array of all stored values within the specified scope [1][2][3]. Official documentation and technical sources do not guarantee a specific chronological order for the records returned by state::list [1][2][4]. The API typically returns data based on the underlying storage adapter's retrieval order, which is generally not guaranteed to be chronological [2][5]. Because the API does not provide built-in sorting or chronological ordering, applications requiring specific ordering (such as newest last or oldest first) must perform sorting client-side after receiving the data [6]. For example, implementations often use standard array sorting methods to organize records based on a timestamp field (e.g., startedAt or createdAt) included within the stored data objects [6].

Sort source records before slicing. StateKV.list() does not guarantee chronological order, and the subsequent filter() and map() calls preserve that unspecified order. Therefore, .slice(-INSIGHT_MAX_SOURCE_IDS) can retain arbitrary provenance records instead of the newest ones. Sort each source collection by its timestamp before taking the final 20 IDs.

Fixes #1168.
