-# 2026-02-23 — Modrinth Install + Full Mod Lifecycle
-
-**Type:** Foundational Architecture + Implementation
-**Status:** Full mod lifecycle complete, file browser next
-
----
-
-## Completed
-
-### API
-
-Implemented full mod lifecycle routes:
-
-```
-GET    /api/game/mods/search?q=&vmid=
-GET    /api/game/servers/:id/mods
-POST   /api/game/servers/:id/mods/install
-PATCH  /api/game/servers/:id/mods/:modId
-DELETE /api/game/servers/:id/mods/:modId
-```
-
-All routes:
-- `requireAuth`
-- Enforce container ownership
-- Enforce `ctype === "game"`
-- Forward to agent with timeout + `502`/`504` mapping
-
-### Resolver
-
-- Loader normalization fixed (`neoforge` / `fabric` / `forge` / `quilt`)
-- `.jar`-only enforcement
-- Host allowlist: `cdn.modrinth.com`
-- Publish-date safe sorting
-- SHA512 preferred (fallback to SHA1)
-
-### Agent
-
-Mod install flow:
-
-- Accepts direct Modrinth artifact URL
-- Validates:
-  - HTTPS only
-  - Allowed host (`cdn.modrinth.com`, `artifacts.zerolaghub.com`)
-  - Max size 200MB
-  - SHA256 hash
-- Writes to `<serverRoot>/mods`
-- Enables via filename convention
-- Soft delete moves to `<serverRoot>/mods-removed`
-- Enable/disable via rename: `.jar` ↔ `.jar.disabled`
-
-### Frontend
-
-- Mod search drawer implemented
-- Installed mods panel implemented
-- Installed flag merged into search results (heuristic matching)
-- Install button functional
-- Enable / disable functional
-- Delete functional
-- Toast notifications added
-
----
-
-## Current System Behavior
-
-Filesystem is source of truth.
-
-No database persistence for:
-- Mod install history
-- Modrinth project ID mapping
-
-Installed matching is heuristic based on:
-- Slug
-- Filename
-- Name
-
-Soft delete retains file permanently in `/mods-removed`. No retention policy implemented (intentional).
-
----
-
-## Known Architectural Tradeoffs
-
-- No deterministic Modrinth project ID persistence yet
-- Installed detection is best-effort heuristic
-- No install queue
-- No auto-update logic
-
----
-
-## Security Controls In Place
-
-**Agent level:**
-- HTTPS-only downloads
-- Host allowlist enforcement
-- Redirect limit (max 3)
-- 200MB hard cap
-- SHA256 verification
-- Filename sanitization (`[a-zA-Z0-9._+-]` — `+` added for Modrinth filenames)
-- Duplicate prevention
-- Ownership enforcement (`minecraft:minecraft`)
-- Temp file cleanup on failure
-- Controlled mod directory write path
-- Cache invalidation after every mutation
-
-**API level:**
-- Auth + ownership enforcement
-- VMID validation
-- Timeout protection with `AbortController`
-- Resolver filtering (loader + version + stability)
-- Correct payload contract to agent
-
----
-
-## Payload Contract (API → Agent)
-
-```json
-{
-  "source": "modrinth",
-  "download_url": "...",
-  "filename": "...",
-  "sha512": "..."
-}
-```
-
-Engine metadata format (corrected this session):
-
-```
-engineType    = "neoforge"   (not "minecraft")
-engineVersion = "1.21.4"     (not "neoforge-1.21.4")
-```
-
----
-
-## Remaining Issues
-
-### Response Corruption (Needs Verification)
-
-One early `curl` output appeared corrupted. Reproduce before wiring portal:
-
-```bash
-curl -sS -D headers.txt -o body.txt ...
-```
-
-### API Error Mapping Refinement
-
-- `"mod already exists"` should return `409` (currently `502`)
-
----
-
-## Next Steps
-
-1. Reproduce and resolve response corruption issue
-2. Tighten API error mapping (`409` for duplicate)
-3. Wire install endpoint to portal UI
-4. Begin file browser (see `OPEN_THREADS.md`)
