 - Discovered Gitea creates empty mirror repos on failed async clones (silent failure)
 - Discovered `service: "git"` fails for private repos; `service: "github"` with valid token works
 - Mirror interval set to 1 hour, manual sync available via API
-- Updated HANDOVER.md, lessons-learned.md, and articles with new mirroring approach
+- Rewrote MIRRORING-GUIDE.md with pull mirror approach and all gotchas
+- Updated HANDOVER.md and lessons-learned.md

+### Session 4: 1Password Token Update and Task Tracking
+- Attempted to update `github.personal.token` via `op item edit` -- blocked by service account read-only permissions
+- Confirmed `op_zesticai_non_prod.sh` sources a SERVICE_ACCOUNT with no write access to TerraphimPlatform vault
+- Created GitHub issue to track the fix: https://github.com/AlexMikhalev/cto-executive-system/issues/8

+### All Commits (pushed to GitHub, auto-synced to Gitea)
+- `57eabbb` refactor: Replace GitHub Actions mirroring with Gitea native pull mirror
+- `0e69456` docs: Update handover with articles, publishing, and new lessons learned
+- `62e2275` docs: Add articles comparing beads/br/agent-mail with Gitea replacement

 ### Next Steps
-1. Update `github.personal.token` in 1Password (currently expired)
-2. Consider adding gitea-mcp or forgejo-mcp as MCP server for Claude Code (see SKILL.md MCP Integration section)
-3. Create first real milestone and tasks in `terraphim/agent-tasks` for a project
-4. Consider Phase 4 (disciplined-verification) if more rigorous validation is needed
+1. Update `github.personal.token` in 1Password manually (service account is read-only) -- tracked in https://github.com/AlexMikhalev/cto-executive-system/issues/8
+2. Grant write access to `op_zesticai_non_prod` service account on TerraphimPlatform vault
+3. Consider adding gitea-mcp or forgejo-mcp as MCP server for Claude Code (see SKILL.md MCP Integration section)
+4. Create first real milestone and tasks in `terraphim/agent-tasks` for a project

 1. **Simplest mirroring wins** -- Gitea pull mirror is one API call to set up, zero maintenance, and replaces two GitHub Actions workflows plus a monitoring check.
 
 2. **Use `gh auth token` as GitHub token source** -- more reliable than maintaining a separate PAT in 1Password. The `gh` CLI handles token refresh automatically.

+## Session: 2026-02-18 -- 1Password Service Account Limitations
+
+### Technical Discoveries
+
+1. **1Password service accounts are read-only by default**
+   - `op_zesticai_non_prod.sh` sources a SERVICE_ACCOUNT (type visible via `op whoami`)
+   - Service accounts can `op read` but `op item edit` fails with "Couldn't update the item"
+   - No specific error about permissions -- just a generic failure message
+   - Write access must be granted explicitly in 1Password admin settings per vault
+
+### Pitfalls to Avoid
+
+1. **Do not assume `op item edit` works with service accounts** -- test write access before building automation that depends on it. The error message gives no indication that it's a permissions issue.
+
+### Best Practices Discovered
+
+1. **Track infrastructure tasks in a central repo** -- Created issue in `AlexMikhalev/cto-executive-system` to track the token update. This prevents losing track of manual steps that couldn't be automated.
