Updated NIP-09 section to document full implementation including:
- 'e' tags for deleting regular events by event ID
- 'a' tags for deleting addressable events by address format (kind:pubkey:d-identifier)
This reflects the implementation added in commits 3ba3318 and 538fe42 which brought the relay into full NIP-09 compliance.
Fixed bug where deleting a parameterized replaceable event (e.g., kind 31922)
using an 'a' tag would incorrectly delete ALL events of that kind instead of
just the specific event with the matching d-tag.
**Root Cause:**
NostrFilter's 'd' field uses a Pydantic Field alias "#d". When creating a filter
with `NostrFilter(d=[value])`, Pydantic ignores it because the parameter name
doesn't match the alias.
**Fix:**
Changed filter creation to use the alias:
```python
NostrFilter(authors=[...], kinds=[...], **{"#d": [d_tag]})
```
**Testing:**
- Created two tasks with different d-tags
- Deleted only one task
- Verified only the specified task was marked as deleted in the database
- Confirmed the other task remained unaffected
This ensures proper NIP-09 deletion behavior for NIP-33 parameterized
replaceable events using 'a' tag format (kind:pubkey:d-identifier).

Extended NIP-09 deletion event handling to support both regular events
and parameterized replaceable events (NIP-33).
**Previous behavior:**
- Only handled 'e' tags (regular event IDs)
- Did not support 'a' tags for addressable/replaceable events
**New behavior:**
- Handles both 'e' tags (event IDs) and 'a' tags (event addresses)
- Parses 'a' tag format: kind:pubkey:d-identifier
- Validates deletion author matches event address pubkey (NIP-09 requirement)
- Creates appropriate filters for each deletion type
**Implementation:**
- Added parsing for 'a' tag event addresses
- Extract kind, pubkey, and d-tag from address format
- Build NostrFilter with authors, kinds, and d-tag parameters
- Collect all event IDs to delete from both 'e' and 'a' tags
- Mark matching events as deleted in single operation
This enables proper deletion of parameterized replaceable events like
calendar events (kind 31922-31924), long-form content (kind 30023),
and other addressable event kinds.

* Implement NIP-16 parameterized replaceable events
Add support for parameterized replaceable events (kinds 30000-39999) to
properly
handle Nostr marketplace product and stall updates according to NIP-16
specification.
Changes:
- Add is_parameterized_replaceable_event property to NostrEvent
- Implement automatic deletion of previous versions when new
parameterized replaceable event is received
- Add 'd' tag filtering support to NostrFilter for parameterized
replacement logic
- Update SQL query generation to handle 'd' tag joins
Fixes issue where product updates would create duplicate entries instead
of
replacing previous versions, ensuring only the latest version remains
visible.
* Refactor event handling for addressable events
Renamed the property is_parameterized_replaceable_event to is_addressable_event in NostrEvent to align with NIP-01 specifications (previously NIP-16). Updated the client_connection.py to utilize the new property for extracting 'd' tag values for addressable replacement, ensuring proper event handling in the relay system.
* Refactor tag filtering logic in NostrFilter
Updated the tag filtering mechanism to ensure that the filter only fails if the specified tags ('e' and 'p') are not found. This change improves clarity and maintains functionality by allowing for more precise control over event filtering.
* update readme
* Fix addressable event deletion and SQL schema issues
- Fix Pydantic field alias usage for d tag filtering (use #d instead of
d)
- Remove nostrrelay schema prefixes from SQL table references
- Implement subquery approach for DELETE operations with JOINs
- Resolve SQLite DELETE syntax incompatibility with JOIN statements
- Ensure NIP-33 compliance: only delete events with matching d tag
values
This fix addresses an issue where REQ messages with multiple filters
were being rejected by the relay. Notably: The nostrmarket extension's
"Refresh from Nostr" functionality sends a single REQ message containing
4 different filter subscriptions:
- Direct Messages (kinds: [4])
- Stalls (kinds: [30017])
- Products (kinds: [30018])
- Profile (kinds: [0])
Changes:
- Changed validation from `len(data) != 3` to `len(data) < 3` to allow
multiple filters
- Added loop to process all filters in a single REQ message (data[2:])
- Accumulate responses from all filters before returning
This ensures compatibility with clients that batch multiple subscription
filters in a single REQ message, which is a valid pattern according to
NIP-01.
to errors while loading relay configuration from the DB and that also
caused the loaded meta information to be invalid. Mandatory fields for
NostrRelay were not selected by the query, and a dictionary
representation of the meta object should not be returned as it causes
some members such as require_auth_filter and event_requires_auth to not
be accessible, leading to breaking exceptions.
