#1000 was stale-fixed: BrainService::recall() validates filter input
via the shared validator at line 489, which already bounds org,
project, type, agent_id. forget() bounds id at line 499.
These tests pin the safety claim explicitly:
- project=129 chars rejected
- agent_id=65 chars rejected
- project="core" accepted (sanity)
- project=128 chars accepted (boundary)
Note: BrainList.php (separate MCP list path) still lacks explicit
max lengths for project + agent_id — file outside this lane's allow-
list. File a follow-up if that surface needs the same bounds.

Bound input field sizes against memory/DB/Qdrant bloat (DoS-by-self):
- content: 65536 bytes via mb_strlen
- tags: max 100 entries; each tag max 128 chars
- agent_id, type: 64 chars each
- project, org: 128 chars each
- supersedes_id: ULID-shape only
validateRememberInput() throws InvalidArgumentException at every entry
point (remember, recall, forget) before any DB or upstream call. Field-
specific error messages so callers know which field violated.
Pest covers good-path, content-too-long, tags-array-too-large, tag-
length, exact-boundary cases.
