🧹 Nitpick comments (7)
docs/schema.md (6)
22-28: Clarify stream identity and constraints.You have both
idandstream_id. Clarify:
- Is
stream_ida human-readable identifier? Is it globally unique or unique perdata_provider_id?- Define UNIQUE constraints accordingly (e.g., UNIQUE(data_provider_id, stream_id)).
- Document valid values for
stream_type(enum) and whether it’s constrained.
41-54: Define taxonomy integrity rules (uniqueness, cycles, effective dating).To keep hierarchies sound:
- Enforce no cycles (e.g., via application logic or triggers).
- Add UNIQUE constraints to prevent duplicates, e.g., UNIQUE(stream_ref, child_stream_ref, start_time) or with group_sequence if required.
- Clarify whether
start_timepairs with anend_timeor relies ondisabled_atfor bitemporal semantics.
55-69: Metadata model: ensure determinism and efficient lookup.With a wide KV table:
- Consider UNIQUE(stream_ref, metadata_key, created_at) if multiple values over time are allowed, or UNIQUE(stream_ref, metadata_key) if only one active at a time.
- Add indexes: (stream_ref, metadata_key, disabled_at), and possibly partial index where disabled_at IS NULL for fast “active” lookups.
- If multiple type columns are mutually exclusive, document the rule (only one of value_i/value_f/value_b/value_s/value_ref set).
10-18: Provider address: document uniqueness and canonical form.If
addressis a blockchain address, state:
- Canonical representation (checksum/encoding, case sensitivity).
- Uniqueness (UNIQUE(address)).
- Whether multiple addresses can map to a single provider entity.
3-5: Add operational details: time zone and referential targets.
- Specify the canonical time zone (UTC recommended) for all timestamp fields.
- For FKs, name the exact targets (e.g.,
stream_ref→ streams.id). This avoids ambiguity withstream_id.
35-40: Revisit composite PK design forprimitive_eventsIncluding
created_atin the primary key can make upserts and deduplication more complex. Typical time-series tables use:
- Primary key: (
stream_ref,event_time)- Secondary indexes:
- (
stream_ref,event_timeDESC) for latest‐per‐stream queries- (
stream_ref,created_at) if you need insertion‐order lookupsPlease confirm whether you actually expect multiple records with the same (
stream_ref,event_time). If not, removecreated_atfrom the PK (docs/schema.md lines 35–40) and add it as a separate index instead.README.md (1)
15-17: Add a one-line description for consistency with other sections.Other sections include a short intro sentence before the link. Mirror that for uniformity.

Fix image path: leading slash will break rendering on GitHub.
In Markdown on GitHub, /docs/images/schema.png resolves from the site root, not the repo. Use a relative path from this file instead.
Apply this diff:
-
+Run this script to verify the image actually exists and the link renders relative to docs/schema.md:

Fix image path and alt text in docs/schema.md
The image exists at docs/images/schema.png, so from docs/schema.md it should be referenced relatively, not from the site root. Also update the alt text for clarity.

In docs/schema.md around line 6, the image reference uses an absolute root path
and unclear alt text ("Schema"); change the markdown image to use a relative
path to the image file (e.g. ./images/schema.png) and update the alt text to a
clearer description such as "Database schema diagram" so the file renders
correctly from the docs directory and has meaningful alt text.

🛠️ Refactor suggestion
Specify column types, nullability, defaults, and constraints.
The “Type” column is empty for multiple fields. This limits the doc’s usefulness when implementing clients or reviewing migrations.
Recommendations:
- Add concrete DB types (e.g., uuid/text/bigint/timestamp), nullability (NOT NULL/NULL), and default values.
- Call out unique constraints (e.g., address UNIQUE), and indexes commonly used by queries.
If helpful, I can generate a DDL template aligned with your Kwil/SQL dialect.

In docs/schema.md around lines 13 to 18, several fields are missing concrete
column metadata; update the Type column to include precise DB types (e.g.,
uuid/text/timestamp/bigint), explicit nullability (NOT NULL or NULL), and any
default expressions (e.g., auto-generated UUIDs or current_timestamp) for each
field; mark primary key (id) and call out constraints such as address UNIQUE and
any indexes (e.g., frequent query columns like address or created_at) so the
table row shows type, nullability/default, and constraints/index
recommendations.
