Conflict resolution: scripts/type-equiv.manifest.json takes master's new paired-derivative format (one primary entry per pair) and re-adds this stack's CodeDispatchLog entry in that format. zh README pairs brought along for the dispatch-log arm (spill-policy behavior/limitations bullets, tools limitation bullet now pointing at the shipped bounding).
spill/ - spill storage capability family
English | 中文
The tool-output spill capability seam: an abstract storage interface, a local filesystem implementation, and the tool-result policy that uses it. All product packages.
| Package | Role | ctx key |
|---|---|---|
spill/ |
Abstract spill storage seam (saveText — persist oversized tool text and return a locator + retrieval hint) |
ctx.spillStore |
spill-local/ |
Local-filesystem backend: private, session-scoped files with traversal-safe names | (registers on ctx.spillStore) |
spill-policy/ |
tools/post-execute policy: replaces oversized plain-text results with a preview + spill locator |
(no service surface) |
The interface lives at spill/spill/. The split mirrors bash/fs: the seam owns storage only, spill-local owns the filesystem mechanics, and spill-policy owns WHEN to spill and the model-facing notice. Preview mechanics stay in util/retention — the policy composes the two without either owning the other's job.
See the tool output spill Agent Note for the design rationale, including why final-result spill is separate from tool-owned early spill (bash streams, subagent rollouts) and why creation belongs to the runtime spill seam rather than the model-facing write tool.
