+## Current sprint — gitea-mcp v0.2 patch (2026-05-14)
 
 ### Context
-This sprint implements new MCP tools needed for `hyperguild new-project` —
-the automated project creation flow triggered from claude.ai. See brain knowledge
-nodes `adr-new-project-gitea-first-github-mirror` and `roadmap-github-ingestion-pipeline`
-for full background.
+The main v0.2 batch (repo_create, repo_update, repo_mirror_push, repo_delete,
+repo_tree, repo_topics_update, file_read dir-fix, issue_get, release_create,
+create_project_from_template) was implemented and pushed directly to main.
 
-### Issues to implement (priority order)
+This sprint fixes three remaining gaps found during code review on 2026-05-14.
+These are blockers for `hyperguild new-project`.
 
-**Batch 1 — blockers (do first, one PR: `feat/repo-crud`)**
+### Issues to fix (all three in one PR: `fix/v02-patch`)
 
-| Issue | Tool | Gitea API |
-|-------|------|-----------|
-| #13 | `repo_create` | POST /api/v1/user/repos or /api/v1/orgs/{org}/repos |
-| #16 | `repo_mirror_push` (add/list/delete) | POST/GET/DELETE /api/v1/repos/{owner}/{repo}/push_mirrors |
-| #12 | `repo_update` | PATCH /api/v1/repos/{owner}/{repo} |
+#### #12 — repo_update: add `archived` and `template` fields
+**File:** `internal/gitea/repos.go` → `UpdateRepoArgs` struct
+**File:** `internal/tools/repo_update.go` → input schema + args struct
 
-**Batch 2 — quality of life (second PR: `feat/repo-ux`)**
+Add to `UpdateRepoArgs`:
+```go
+Archived *bool
+Template *bool
+```
 
-| Issue | Tool | Gitea API |
-|-------|------|-----------|
-| #15 | `file_read` dir-path fix | existing endpoint, detect array vs object response |
-| #14 | `repo_tree` | GET /api/v1/repos/{owner}/{repo}/git/trees/{sha}?recursive=true |
-| #18 | `repo_topics_update` | PUT /api/v1/repos/{owner}/{repo}/topics |
+Add to tool input schema:
+```json
+"archived": {
+  "type": "boolean",
+  "description": "Mark repo as archived (read-only). Requires confirm=<repo name>."
+},
+"template": {
+  "type": "boolean",
+  "description": "Toggle template repo flag."
+}
+```
 
-**Batch 3 — can wait**
+Add confirm-guard for `archived=true` (same pattern as `private=false`):
+```go
+if args.Archived != nil && *args.Archived {
+    if args.Confirm != args.Name {
+        return nil, fmt.Errorf("setting archived=true is irreversible: set confirm=%q to proceed", args.Name)
+    }
+}
+```
 
-| Issue | Tool | Note |
-|-------|------|------|
-| #11 | `repo_delete` | HIGH risk — needs `confirm` param == repo name |
-| #17 | `release_create` | POST /api/v1/repos/{owner}/{repo}/releases |
+New test cases to add in `repo_update_test.go`:
+- `TestRepoUpdateTool_Archive` — happy path with confirm
+- `TestRepoUpdateTool_ArchiveRequiresConfirm` — missing confirm returns error
+- `TestRepoUpdateTool_SetTemplate` — no confirm needed
 
-### How to add a tool (pattern)
+#### #24 — create_project_from_template: make template selectable
+**File:** `internal/tools/create_project_from_template.go`
 
-Every tool = 4 files following `internal/tools/repo_get.go` exactly:
+Add optional `template_name` param to input schema:
+```json
+"template_name": {
+  "type": "string",
+  "enum": ["template-go-web", "template-go-agent"],
+  "description": "Template repo to generate from. Defaults to template-go-web.",
+  "default": "template-go-web"
+}
+```
 
-1. `internal/gitea/<domain>.go` — API client method (use PostJSON/PatchJSON/DeleteJSON)
-2. `internal/tools/repo_<name>.go` — tool handler with Descriptor() + Call()
-3. `internal/tools/repo_<name>_test.go` — table-driven tests with httptest.NewServer
-4. Registration in main — find where `NewRepoGet` is registered, add new tool same place
+The tool should use `args.TemplateName` if set, fall back to the hardcoded default.
+Remove the hardcoded template name from `cmd/gitea-mcp/main.go` constructor call —
+the tool resolves it internally.
 
-Key rules:
-- Always call `t.a.Check(args.Owner)` before any API call (allowlist guard)
-- Use `textOK(result)` for success output
-- For `repo_mirror_push`: NEVER log or return `remote_password` in any output
-- For `repo_update` with `private: false` and `repo_delete`: require `confirm` param == repo name
+New test case: `TestCreateProjectFromTemplate_AgentTemplate`
 
-### Token permissions needed
+#### #25 — pr_files_diff: fix same diff returned for all files
+**File:** `internal/tools/pr_files_diff.go`
 
-New tools require these additional Gitea token scopes:
-- `write:repository` — repo_create, repo_update, repo_mirror_push, repo_topics_update, release_create
-- `delete_repo` — repo_delete
+There is a loop bug where all file entries in the response contain the same diff
+(the first file's diff is reused for every subsequent file). Find the loop and
+ensure each iteration reads and assigns the correct diff for its own file.
 
-Check current token: `curl -H "Authorization: token $GITEA_TOKEN" https://gitea.d-ma.be/api/v1/user`
-If scopes are missing, update token in Gitea settings before running tests.
+Reproduce: call `pr_files_diff` on any PR with 3+ files, verify each file has
+a distinct diff.
 
 ### Definition of done
 
-- `task check` passes (all tools, all batches)
-- Each new tool manually callable via `claude mcp call`
-- PR #1 (batch 1) merged before starting batch 2
-- Issue #19 (mirror flow e2e test) verified manually after batch 1 is deployed
+- [ ] `task check` passes

+- [ ] `pr_files_diff` returns distinct diff per file
+- [ ] All new test cases pass
+- [ ] PR `fix/v02-patch` merged to main via PR (not direct push)

+Next: `hyperguild new-project` v1 implementation.
+See brain node `adr-new-project-gitea-first-github-mirror` for the full flow spec.
+Also: verify end-to-end mirror flow (issue #19) once `repo_mirror_push` is confirmed working.

-- `delete_repo` — repo_delete
+There is a loop bug where all file entries in the response contain the same diff
+(the first file's diff is reused for every subsequent file). Find the loop and
