Database schema

Sadie is Postgres-only. The full, authoritative schema is packages/db/src/schema.ts: roughly 1.6k lines of Drizzle table definitions with typed JSONB columns via .$type<T>(). This page groups the tables by domain and calls out notable shapes; for column-level detail, read the file.

Identity

Table	Notes
users	Better-Auth-compatible (id, email, emailVerified, name, image) plus Sadie fields (displayName, avatarColor, role). One row per deployment. This is a single-user product.
sessions	Cookie sessions. Indexed on token.
accounts	Better-Auth account rows; reserved for future SSO.
verifications	Better-Auth verification tokens. Unused today.

Chat

Table	Notes
conversations	sadieEmotion column carries one of seven emotions; set per-message and persisted on the conversation.
messages	status is `streaming
chat_context_attachments	Removable context chips: kind is `discourse

Studio

Table	Notes
studio_workspaces	A user can have many workspaces. colorToken picks the Clay accent.
documents	Tiptap + Yjs. ydocState is base64-encoded binary Yjs update. wikiEntryId set when the draft is filed into Memory.
comments	Text-anchored via anchorFrom/anchorTo integer offsets.
studio_collaborator_grants	Local-only collaborator grants; no email send yet.

Sources

Table	Notes
sources	Library of everything Sadie reads. kind covers notes, docs, past posts, articles, RSS, newsletters, Notion, Obsidian, Readwise, uploads. weighting is optional: `personal_library
source_weightings	Audit trail when weighting changes.

Feeds

Table	Notes
feeds	Per-user tracked handle (x_account, rss, newsletter).
feed_items	Per-user items. Retained for backward compat with code that queries by feed id.
global_feed_items	Deduplicated across users, keyed by (source, externalId). One X API call per handle, fanned out to all subscribers.
user_feed_item_links	Join table from user feeds to global_feed_items.
feed_theme_counts	Rolling theme aggregates for feed-to-wiki promotion.

Wiki + Memory

Table	Notes
wiki_entries	kind is `person
wiki_patch_events	Provenance trail. Before/after hashes, trigger kind, source ID. Idempotent by (wikiEntryId, afterHash).
wiki_link_candidates	Candidate cross-links awaiting review before becoming durable graph edges.
knowledge_nodes	Graph nodes. kind is `wiki
knowledge_edges	relation is `mentions

Soul

Table	Notes
soul_state	Typed items: `audience
voice_portrait	8-dimension voice model with exemplars, systemPrompt, rewriteAdjustments per dimension.
soul_narrative	Six prose sections: work_context, personal_context, top_of_mind, three tiers of brief_history_*.
preference_candidates	Observed preferences before promotion to Soul. Three kind-families: legacy generic, substance, voice.
rewrite_events	Captured when the user edits Sadie’s output. dimensionDeltas array feeds voice adjustments.

Briefs

Table	Notes
briefs	Editorial syntheses. anchorWikiIds and sourceFeedItemIds track provenance. status is `draft

Discourse / Today

Table	Notes
discourse_opportunities	Today cards. Carry whyNow, whyYou, whoTalking (DiscourseVoice[]), angles (DiscourseAngle[] with confidence, engagementScore, topCritique), rank, accent. status is `active

Policy

Table	Notes
policies	Deterministic guardrails. kind is `regex
policy_violations	Audit trail per match.

Agent evolution

Table	Notes
agent_versions	Immutable config snapshots. config JSONB holds prompts, weights, policies, catalog. parentVersionId forms the lineage. status is `committed
compile_runs	Audit log for every background job. kind covers onboarding, incremental, lint, discourse_refresh, soul_promotion, soul_decay, agent_evolution.
compile_cursors	Per-user watermarks for incremental processing.
lint_findings	Wiki health-check surface. kind enumerates orphan, stale, weak provenance, contradiction, missing page, low linkage, soul contradiction, soul decayed.

Settings

Table	Notes
sadie_settings	JSONB payload with persona defaults, cadences, AI provider preference, encrypted userApiKeys, engagement weights, XP weights, currentAgentVersionId.
onboarding_state	step tracks progress through the 8-step flow. data JSONB accumulates calibration, rewrite drills, scenario checks, and learned writing weights.

Activity

Table	Notes
activity	Everything the user does in the app, keyed by (kind, subjectKind, subjectId). Feeds the agent evolution XP calculation and the Memory activity timeline.

Typed JSONB

Many columns use .$type<T>() to brand their JSONB with a TypeScript type. Compile-time only; Postgres still stores real JSONB and can index into it. Notable types:

• SadieSettingsPayload. Everything in sadie_settings.payload.
• AgentConfig. Prompts + weights + policies + catalog per version.
• VoiceDimension[] / VoiceExemplar[]. Voice portrait contents.
• NarrativeSection[]. Soul narrative.
• OnboardingData. Calibration + distillation state.
• DiscourseAngle[] / DiscourseVoice[]. Today card shapes.

See packages/db/src/schema.ts for every branded type. Drizzle returns these as typed values; the database stores them as plain JSONB.
