- #130243: \[Bug\]: \`_runtime_cache\` in \`agent/moa_loop.py\` is never evicted, so every resolved (profile, provider, model) runtime — including its resolved api_key — is retained for the life of the process
- PR #130250: fix(agent): evict stale MoA runtime cache entries
- PR #131451: fix(cache): bound the credential-keyed process caches (rebase of #130664)

A bug was identified where the \`_runtime_cache\` in \`agent/moa_loop.py\` is never evicted, retaining looked-up API keys and runtime entries indefinitely. The associated fixes add expiration and eviction logic to bound the cache size.

- Internal-tracker verdict over this cluster's issue members: `unresolved`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.
- Pairwise link density `0.50`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.
