32-32: Consider if global name uniqueness is appropriate for automated agents.The unique constraint on
nameensures no duplicate automated agent names. While this prevents confusion, consider whether agent names should be globally unique or scoped to a specific context (e.g., per platform or space).If global uniqueness is intended, this is correct. If scoped uniqueness is preferred, consider a composite unique constraint.
53-53: Consider if global name uniqueness is appropriate for persons.Similar to automated agents, this enforces global uniqueness of person names. This might be too restrictive if multiple people can have the same name in the system.
Please clarify the business requirements: Should person names be globally unique, or is this too restrictive for real-world usage where multiple people may share names?
packages/database/supabase/schemas/content.sql (1)
48-48: Consider implications of global URL uniqueness.The unique constraint on
urlenforces that each URL can only exist once across all documents. This prevents duplicate document imports but consider:
- Performance: This index will be checked on every document insert/update
- Business logic: Is it valid to have the same URL in different spaces or contexts?
Please verify that global URL uniqueness aligns with business requirements. If documents can legitimately have the same URL in different contexts, consider a composite constraint instead.
packages/database/supabase/schemas/space.sql (1)
29-29: Space.url uniqueness without NOT NULL constraint
Theurlcolumn in"Space"is nullable, so the unique index will allow multipleNULLentries. If URLs must be unique when present, consider adding aNOT NULLconstraint onurlor turning this into a partial index (e.g.,WHERE url IS NOT NULL).packages/database/supabase/migrations/20250526150535_uniqueness.sql (2)
3-3: Add unique index on Platform.url
Consider usingCREATE UNIQUE INDEX IF NOT EXISTS ... CONCURRENTLYto avoid locking the table on large datasets.
5-5: Add unique index on Space.url
Similarly, think aboutIF NOT EXISTSandCONCURRENTLYfor production safety.packages/database/supabase/schemas/account.sql (1)
50-50: Update comment forSpaceAccess.account_id
The comment still refers to “person”; consider updating to reflect “account” (e.g., “The identity of the account in this space”).packages/database/schema.yaml (1)
193-195: Add unique_keys for Space.url
Consider markingurlas required in the model or defining this as a partial key (only whenurlis present), to match database constraints.

packages/database/schema.puml (2)
12-12: LGTM: New field addition aligns with unique key requirements.The addition of
account_local_idfield to the Account class properly reflects the schema changes for enforcing uniqueness constraints mentioned in the AI summary.
108-108: LGTM: Relationship label update reflects attribute rename.The change from
"person"to"agent"correctly reflects the attribute rename frompersontoagentin the Account class, maintaining consistency with the underlying schema changes.packages/database/supabase/schemas/concept.sql (2)
67-67: LGTM: Unique constraint enforces concept name uniqueness per space.The unique index on
(space_id, name)appropriately ensures that concept names are unique within each space while allowing the same name across different spaces. This is a well-designed constraint for maintaining data integrity.
26-26:❓ Verification inconclusive
Verify existing data compatibility before enforcing NOT NULL constraint.
Making
space_idNOT NULL enforces that every concept must be associated with a space, which improves data integrity. However, this change could cause migration failures if existing concepts have NULL space_id values.Please run this script to check for existing NULL space_id values:
🏁 Script executed:
#!/bin/bash # Description: Check for concepts with NULL space_id that would violate the NOT NULL constraint # Expected: No results, or migration script should handle these cases echo "Checking for concepts with NULL space_id..." # This would typically be run against the actual database, but we can check if migration handles this fd -e sql -x grep -l "space_id.*NULL" {} \; | head -5Length of output: 323
Action Required: Verify and Clean NULL space_id Values Before Applying NOT NULL Constraint
Before enforcing
space_id bigint NOT NULLinpackages/database/supabase/schemas/concept.sql, ensure no existing records will violate the constraint:
- Run a query in each target database environment:
SELECT COUNT(*) AS null_space_ids FROM concept WHERE space_id IS NULL;- If any rows are returned:
- Decide on and assign an appropriate
space_id(backfill) or remove those records.- Incorporate a pre-migration UPDATE step in your migration scripts (e.g. in
packages/database/supabase/migrations/20250526150535_uniqueness.sqlor a new migration) to handle nulls.- Once data is clean, apply the NOT NULL change and deploy the uniqueness index as planned.
This will prevent migration failures and ensure data integrity.
packages/database/supabase/schemas/agent.sql (1)
54-54: LGTM: ORCID uniqueness is appropriate.ORCID identifiers are globally unique by design, so enforcing uniqueness at the database level is correct and prevents data integrity issues.
packages/database/supabase/schemas/content.sql (2)
45-46: LGTM: Appropriate uniqueness constraint for documents per space.The unique constraint on
(space_id, source_local_id)withNULLS DISTINCT WHERE space_id IS NOT NULLcorrectly ensures that documents with the same source_local_id cannot exist in the same space, while allowing documents without a space_id assignment.
122-124:❓ Verification inconclusive
Verify the semantic change in Content uniqueness constraint.
The index was renamed from
"Content_space_and_id"tocontent_space_and_local_id_idxand the condition changed fromWHERE source_local_id IS NOT NULLtoNULLS DISTINCT WHERE space_id IS NOT NULL. This changes the uniqueness semantics:
- Before: Unique (space_id, source_local_id) where source_local_id is not NULL
- After: Unique (space_id, source_local_id) where space_id is not NULL, treating NULLs as distinct
Please verify this semantic change is intentional. The new constraint allows multiple content with the same source_local_id if space_id is NULL, which may not be desired behavior.
Double-check Content uniqueness filter change
It looks like the UNIQUE INDEX on public."Content" was renamed and its filter was flipped:
- Old index (named
"Content_space_and_id") only covered rows wheresource_local_id IS NOT NULL.- New index (
content_space_and_local_id_idx) covers rows wherespace_id IS NOT NULL, and usesNULLS DISTINCTto treat NULLs as distinct values.This means any row with
space_id = NULL(regardless ofsource_local_id) is no longer included in the index, so duplicates in that situation won’t be prevented. Please confirm that this revised uniqueness constraint—filtering onspace_idinstead ofsource_local_id—is intentional and aligns with your data-model requirements.
