-# Tag Migration to Standard NIP-01 "t" Tags
-
-**Date:** November 4, 2025  
-**Status:** ✅ Complete
-
-## Overview
-
-Migrated audit system tags from custom single-letter tags (`g`, `r`, `c`) to standard NIP-01 "t" tags (hashtags) to avoid conflicts and follow Nostr conventions.
-
-## Motivation
-
-The previous tag scheme used:
-- `g` tag for `grasp-audit` marker
-- `r` tag for `audit-run-id`
-- `c` tag for `audit-cleanup` timestamp
-
-However, this could conflict with other uses of these single-letter tags. The "t" tag is the standard NIP-01 tag type for categorization/topics, making it the appropriate choice for audit event tagging.
-
-## Changes Made
-
-### Tag Structure
-
-**Before:**
-```rust
-vec![
-    Tag::custom(TagKind::SingleLetter(g_tag), vec!["grasp-audit"]),
-    Tag::custom(TagKind::SingleLetter(r_tag), vec![run_id]),
-    Tag::custom(TagKind::SingleLetter(c_tag), vec![cleanup_timestamp]),
-]
-```
-
-**After:**
-```rust
-vec![
-    Tag::custom(TagKind::SingleLetter(t_tag), vec!["grasp-audit-test-event"]),
-    Tag::custom(TagKind::SingleLetter(t_tag), vec![format!("audit-{}", run_id)]),
-    Tag::custom(TagKind::SingleLetter(t_tag), vec![format!("audit-cleanup-after-{}", timestamp)]),
-]
-```
-
-### Tag Values
-
-| Purpose | Old Tag | Old Value | New Tag | New Value |
-|---------|---------|-----------|---------|-----------|
-| Marker | `g` | `grasp-audit` | `t` | `grasp-audit-test-event` |
-| Run ID | `r` | `ci-{uuid}` | `t` | `audit-ci-{uuid}` |
-| Cleanup | `c` | `{timestamp}` | `t` | `audit-cleanup-after-{timestamp}` |
-
-### Example Event Tags
-
-```json
-[
-  ["t", "grasp-audit-test-event"],
-  ["t", "audit-ci-a1b2c3d4-e5f6-7890-abcd-ef1234567890"],
-  ["t", "audit-cleanup-after-1730707200"]
-]
-```
-
-## Files Modified
-
-### `src/audit.rs`
-- Updated `audit_tags()` to use "t" tags
-- Updated tests to check for "t" tag kind
-- All values now prefixed for clarity
-
-### `src/client.rs`
-- Updated `query()` to filter by "t" tags
-- Changed from `.custom_tag(g_tag, ...)` to `.custom_tag(t_tag, ...)`
-
-## Benefits
-
-1. **Standards Compliance**: Uses standard NIP-01 hashtag mechanism
-2. **No Conflicts**: "t" tag is designed for categorization
-3. **Better Namespacing**: Values prefixed with `audit-` to avoid collisions
-4. **Queryable**: Standard tag filtering works as expected
-5. **Self-Documenting**: Tag values clearly indicate their purpose
-
-## Testing
-
-All tests pass with the new tag scheme:
-
-```bash
-# Unit tests
-✓ 12/12 tests passing
-
-# Integration tests  
-✓ 1/1 test passing (NIP-01 smoke tests)
-
-# CLI verification
-✓ All 6 smoke tests pass
-```
-
-## Backwards Compatibility
-
-⚠️ **Breaking Change**: Events created with old tags will not be found by new queries.
-
-This is acceptable because:
-- System is in alpha/development
-- Old events are test data only
-- Cleanup happens automatically via timestamps
-- No production deployments exist yet
-
-## Migration Path
-
-For future tag changes:
-1. Consider versioning in tag values (e.g., `grasp-audit-v2-test-event`)
-2. Support querying both old and new tags during transition
-3. Document breaking changes clearly
-4. Provide migration tools if needed

-## References
-
-- **NIP-01**: https://github.com/nostr-protocol/nips/blob/master/01.md
-- **Tag Standardization**: "t" tags for topics/categories
-- **Previous Implementation**: Commit `8190a3a` (custom g/r/c tags)
-- **Current Implementation**: Uses standard "t" tags
-
-## Verification
-
-To verify the new tag structure:
-
-```bash
-# Run tests
-nix develop -c cargo test --lib
-nix develop -c cargo test -- --ignored
-
-# Run CLI
-nix develop -c cargo run -- audit \
-  --relay ws://localhost:7000 \
-  --mode ci \
-  --spec nip01-smoke
-
-# Check event structure (example)
-# Events will have tags like:
-# ["t", "grasp-audit-test-event"]
-# ["t", "audit-ci-{uuid}"]  
-# ["t", "audit-cleanup-after-{timestamp}"]
-```
-
-## Next Steps
-
-- [ ] Update documentation to reflect new tag scheme
-- [ ] Consider adding tag validation helpers
-- [ ] Document tag format in API/spec documentation
-- [ ] Add examples showing tag usage
