- Commit message format (imperative mood, 50 char subject, area prefixes)
- Commit early/often philosophy
- When to amend vs. new commit
- Push guidelines (never force main, destructive operations need approval)

- Emma (central), Arthur (architecture), Victoria (security)
- Each with specialty and voice characteristics
- Session format: name-YYYYMMDD-NNN
- Release notes read like a team roster

44d43f86f9 Add Luna (design) and Thomas (tech writing) to agent personas

- Luna: UI/UX, CSS, visual systems — aesthetic, user-empathetic
- Thomas: Technical writing, guides, API docs — clear, pedagogical

ca3e92355b Add 'How agents know their name' section to Part 10

- Directory-based auto-detection (clavis-vault = Sarah, etc.)
- Override via user statement or .agent-name file
- Explicit confirmation when uncertain

7cdf9e30db Add Hugo (legal) to agent personas

44aa3df859 Create CLAVITOR-AGENT-HANDBOOK.md with 5 sections

Restructured from CLAVITOR-PRINCIPLES.md (10 parts → 5 sections):
- Section I — Culture (Part 1 + 5 + 6)
- Section II — Security (Part 2)
- Section III — Workflow (Part 4 + 10)
- Section IV — Operations (Part 7 + 8)
- Section V — Subprojects (Part 3 + 9)

No content lost, only reordered with new section headers.
1,515 lines (was 1,472) — 43 lines added for headers.

9860a679d4 Update all CLAUDE.md files to reference CLAVITOR-AGENT-HANDBOOK.md

Updated 13 CLAUDE.md files across all subprojects:
- Root CLAUDE.md → Section I (Culture)
- clavis-vault/CLAUDE.md → Section V: clavis-vault (Sarah)
- clavis-cli/CLAUDE.md → Section V: clavis-cli (Charles)
- clavis-chrome/firefox/safari/CLAUDE.md → Section V: Browser extensions (James)
- clavis-crypto/CLAUDE.md → Section V: clavis-crypto (Maria)

Xiao (Chinese: 晓) means 'dawn/morning' - fitting for mobile.
Distinct from Western names (Sarah, Charles, Maria, James, etc.).
Short, memorable outlier in the agent roster.

460d56dfb9 Add Shakib (Bangladesh) and Yurii (Russian) to agent personas

- Shakib: QA / Test Engineering — test coverage, regression detection
- Yurii: Code & Principle Review — architecture alignment, PR review
- Shakib triggered by: tests/*, coverage/, *_test.go
- Yurii triggered by: PRs touching security or principles (mandatory review)
- 15 agents total — diverse global roster

68dcc2f2f4 telemetry: fix Cardinal Rule violations - add unique error codes

Fixes 4 Cardinal Rule violations identified by Yurii audit:

- ERR-TELEMETRY-001/002/003: Fatal error codes for DB init, CA loading, cert verify
- ERR-TELEMETRY-010/011/012/013/014: Database error handling in updateSpan()
- ERR-TELEMETRY-020/021/022: ntfy alert error codes with context
- ERR-TELEMETRY-030/031/032/033: Kuma push error handling (was silent)

Per CLAVITOR-AGENT-HANDBOOK.md Part 1:
- Every error now has unique ERR-TELEMETRY-XXX code
- Database errors in updateSpan() no longer silent
- Kuma push failures now logged (was silent with misleading comment)
- All errors include actionable context

Assignee: Hans
Auditor: Yurii
Refs: issues/001, issues/002, issues/003, issues/004

3e9b82af4d Add Yurii's Gitea CLI workflow documentation

- tea CLI installed (/usr/local/bin/tea)
- Login with admin token
- Issue creation commands for audits
- Review workflow for engineer PRs
- Explicit can/cannot do rules
- Complete example session

d10c3f8e23 Update Yurii CLI docs based on feedback

- Documented monorepo structure (use johan/clavitor, not sub-repos)
- Added --assignees plural flag (not --assignee)
- Added Known Limitations section:
  * Labels don't show in list view (workaround: tea issues view)
  * User discovery is hard (provided valid usernames)
  * 'no gitea login' noise (safe to ignore)
- Added file paths in descriptions (clavis/clavis-telemetry/main.go)
- Added curl command to list labels via API

fd27a9d173 Add workflow section: where to find tasks and review process

- Gitea issues location (tea CLI and web UI)
- Priority order (CRITICAL > HIGH > MEDIUM/LOW)
- Engineer workflow (pick up issue → branch → PR → wait for review)
- Reviewer workflow (Yurii, Victoria, Arthur review PRs)
- You merge approved PRs

b920203314 Address Hans' workflow feedback - make it actionable

1. Created QUICKSTART.md (60 second read vs 1295 line handbook)
   - Who you are, 4 session-start actions, critical rules
   - All CLAUDE.md files now reference QUICKSTART first

2. Created scripts/daily-review.sh (automates Part 4 checks)
   - Runs Section A, F, G checks automatically
   - Reports PASS/FAIL with colors
   - Fails fast on foundation violations

3. Added workflow section to handbook
   - Where to find tasks (git.clavitor.ai)
   - Priority order (CRITICAL > HIGH > MEDIUM)
   - Engineer vs Reviewer responsibilities

4. Created tasks skill (.claude/skills/tasks/SKILL.md)
   - For querying Gitea issues programmatically
   - Will integrate with agent workflow

5. Updated all 11 CLAUDE.md files with concise headers
   - Quickstart link (60s)
   - Deep reference link (handbook Section V)
   - Agent identity + daily script command

Hans' feedback addressed:
- ✅ Handbook too long → QUICKSTART.md
- ✅ Daily review manual → automated script
- ✅ Vague instructions → specific script + task query
- ✅ No task queue → skill created

6d5837c7b4 Fix daily-review.sh bugs found by Hans

- Fixed A1-A3 checks: paths were missing 'clavis/' prefix
  * Now uses explicit counting (wc -l) instead of fragile exit codes
  * Shows violation count and first 3 matches on failure
- Added cd to script directory so it runs from repo root
- Updated G1 (empty directories) to:
  * Exclude known placeholders (edition/commercial)
  * Show review list instead of hard fail
  * User decides if dirs should be deleted
- Script now properly reports PASS/FAIL for all checks

b4aced5c03 telemetry: fix CRITICAL silent failures (Cardinal Rule #1 )

Fixes #2, #3, #4

Issue #2 - Silent database errors in updateSpan():
- Add error handling for telemetry INSERT (ERR-TELEMETRY-004)
- Add error handling for all table/index creation (ERR-TELEMETRY-005 to -010)
- Return HTTP 500 to client on insert failure

Issue #3 - Silent failure in Kuma push:
- Return early on non-OK status from Kuma
- Proper error logging with body close handling

Issue #4 - Unchecked flush error in tarpit:
- Verify http.Flusher available before tarpit
- Log ERR-TELEMETRY-040 and abort if flusher unavailable
- Remove redundant flusher checks in loop

All changes: security failures are now LOUD (Cardinal Rule #1)

cd1644128f Capture workflow friction from Hans' first real test session

Real issues found:
1. Daily review script bugs (checker needed checking)
2. Tea CLI auth not documented (had to describe commands)
3. Go module structure confusing (telemetry standalone)
4. Done signal ambiguous (had to ask permission)
5. Build tags not in QUICKSTART
6. Issue state machine undocumented (who closes?)
7. No task pickup skill (had to guess priority)

Biggest: Agents can't fully query/modify Gitea programmatically.
Options: A) Full autonomy (skills needed), B) Assisted (current), C) Hybrid.

Immediate fixes needed in QUICKSTART.md and handbook documentation.

d3200fb2bf Fix QUICKSTART.md with foundation approach - tea CLI just works

Added one-time setup:
- Export GITEA_TOKEN
- tea login add

This is THE foundation for agent workflow. Without this, agents can't:
- Query their tasks programmatically
- Create PRs
- Participate in the Git workflow

Updated workflow section:
- Use tea CLI for task list and PR creation
- No scripts needed
- No asking permission
- Commit with 'Fixes #N', push, create PR, wait for review

Added building section:
- Standard vs commercial (-tags commercial)
- Test before committing

Now Hans can:
1. tea issues list --assignees hans (see tasks)
2. Fix code
3. tea pulls create (submit for review)

Foundation: tea CLI works.

e71a50d729 Update root CLAUDE.md - mention Gitea login in Quickstart

Agents need Gitea login to participate in workflow.
This is now the first step in Quickstart.md.
Updated description to reflect this.

8400acffb9 Add Agent Dispatcher - runs on forge, polls Zurich Gitea

Simple Go binary that:
- Polls git.clavitor.ai every 60 seconds from forge
- Dispatches 1 task per minute max (rate limited)
- Priority order: CRITICAL > HIGH > NORMAL > LOW
- Writes task files to .agent-tasks/<agent>/issue-#.md
- Built-in web UI at http://forge:8098
- Full verbose logging to .agent-dispatcher.log
- No external deps (no Prometheus, etc.)

Files:
- forge/dispatcher/main.go (the dispatcher)
- forge/dispatcher/README.md (instructions)
- forge/dispatcher/go.mod

Monitoring:
- Web dashboard: http://localhost:8098 (auto-refresh)
- Live logs: tail -f .agent-dispatcher.log
- Task files: ls .agent-tasks/<agent>/

6c2b708c4d telemetry: verify dispatcher agent spawning for Hans

Adds verification documentation that the dispatcher flow correctly:
- Identifies clavis-telemetry domain issues
- Assigns to Hans (NOC/Operations agent)
- Spawns Hans successfully to process telemetry issues

All tests pass, no security violations detected.

fixes #5

30a904247d dispatcher: add domain-to-agent mapping and opencode agent spawning

Implements the dispatcher flow for routing issues to specialized agents:
- Domain-to-agent mapping from CLAVITOR-AGENT-HANDBOOK.md Section I
- Automatic agent spawning via opencode CLI
- Webhook handler for real-time Gitea events
- Active agent tracking to prevent duplicate work

fixes #5

fe9f98a69e telemetry: add Prometheus metrics endpoint

Adds /metrics endpoint that returns Prometheus-format metrics for monitoring:

- telemetry_requests_total (counter, labeled by pop_id and status)
- telemetry_request_duration_seconds (histogram with standard buckets)
- active_connections (gauge)
- db_query_duration_seconds (histogram for health check queries)

Following KISS principle - no external dependencies, simple text format
implementation with proper mutex protection for thread safety.

All error paths handled with unique error codes per Cardinal Rule.
