-# Session Summary: Upload Pipeline & Filesystem Consolidation
-
-Date: 2026-03-01

-
-## Summary
-
-This session consolidated the file system architecture and resolved issues in the upload pipeline from browser to agent.
-
----
-
-## Filesystem Architecture
-
-Game server filesystem operations are handled exclusively by the agent. The API proxies all requests — it never touches the filesystem directly.
-
-Capabilities documented:
-
-- Read (list, stat, read, download)
-- Write (server.properties, config/*.toml, config/*.json, config/*.properties)
-- Delete (constrained to mods-removed/, mods-uploaded/, logs/)
-- Upload (mods/*.jar, world/datapacks/*.zip)
-- Revert (shadow backup restore)
-
-Shadow backups created on first write. 7-day retention, 6h cleanup cycle.
-
----
-
-## Provenance Tracking
-
-`.zlh_metadata.json` written after every upload:
-
-```json
-{
-  "mods/sodium.jar": {
-    "source": "user",
-    "uploaded_at": "2026-03-01T22:37:01Z"
-  }
-}
-```
-
-`stat` responses include `source: "user" | null`. No curated inference implemented.
-

-
-## Upload Transport Fix (API Layer)
-
-Uploads initially failed with `502` errors when proxied from the API to the agent.
-
-Root cause:
-The Node API upload proxy was forwarding `Content-Length` incorrectly while streaming the request body.
-
-Resolution:
-The upload route now uses a raw Node `http.request` stream:
-
-- `req.pipe(proxyReq)`
-- `proxyRes.pipe(res)`
-- `Content-Type` preserved
-- `Content-Length` not forwarded
-- Upload timeout extended to 5 minutes
-
-This allows large multipart uploads to stream directly from the client → API → agent without buffering.
