+## Current sprint — gitea-mcp v0.2 patch (2026-05-14)
+
+### Context
+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.
+
+This sprint fixes three remaining gaps found during code review on 2026-05-14.
+These are blockers for `hyperguild new-project`.
+
+### Issues to fix (all three in one PR: `fix/v02-patch`)
+
+#### #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
+
+Add to `UpdateRepoArgs`:
+```go
+Archived *bool
+Template *bool
+```
+
+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."
+}
+```
+
+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)
+    }
+}
+```
+
+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
+
+#### #24 — create_project_from_template: make template selectable
+**File:** `internal/tools/create_project_from_template.go`
+
+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"
+}
+```
+
+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.
+
+New test case: `TestCreateProjectFromTemplate_AgentTemplate`
+
+#### #25 — pr_files_diff: fix same diff returned for all files
+**File:** `internal/tools/pr_files_diff.go`
+
+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.
+
+Reproduce: call `pr_files_diff` on any PR with 3+ files, verify each file has
+a distinct diff.
+
+### Definition of done
+
+- [ ] `task check` passes
+- [ ] `repo_update` accepts `archived` and `template` params
+- [ ] `archived=true` requires `confirm=<repo name>`
+- [ ] `create_project_from_template` accepts `template_name` param, defaults to `template-go-web`
+- [ ] `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)
+
+### After this sprint
+
+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.

+This sprint fixes three remaining gaps found during code review on 2026-05-14.
+These are blockers for `hyperguild new-project`.
+
+### Issues to fix (all three in one PR: `fix/v02-patch`)
+
+#### #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
+
+Add to `UpdateRepoArgs`:
+```go
+Archived *bool
+Template *bool
+```
+
+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."
+}
+```
+
+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)
+    }
+}
+```
+
+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
+
+#### #24 — create_project_from_template: make template selectable
+**File:** `internal/tools/create_project_from_template.go`
+
+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"
+}
+```
+
+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.
+
+New test case: `TestCreateProjectFromTemplate_AgentTemplate`
+
+#### #25 — pr_files_diff: fix same diff returned for all files
+**File:** `internal/tools/pr_files_diff.go`
+
+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.
+
+Reproduce: call `pr_files_diff` on any PR with 3+ files, verify each file has
+a distinct diff.
+
+### Definition of done
+
+- [ ] `task check` passes
+- [ ] `repo_update` accepts `archived` and `template` params
+- [ ] `archived=true` requires `confirm=<repo name>`
+- [ ] `create_project_from_template` accepts `template_name` param, defaults to `template-go-web`
+- [ ] `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)
+
+### After this sprint
+
+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.

+create_project_from_template) was implemented and pushed directly to main.
