Summary by Sourcery

Refactor chat and workspace RAG infrastructure to use shared utilities and Drizzle-based persistence, tighten operation metadata and scoping semantics, and update message handling to be type-safe and robust across chat, workspace, and document workflows.

New Features:

  • Introduce shared chat context and RAG helper utilities to prepare chat metadata, build heading context, and orchestrate scoped retrieval across chat and workspace.
  • Add Drizzle-based server actions for assistant answer ingestion and retrieval, and a scope-aware conversation window query implemented directly against the database.
  • Support richer operation metadata and workspace action types, including unknown and ai_action intent variants, for document and chat operations.

Bug Fixes:

  • Fix role and ID handling across chat message flows to prevent case mismatches and duplicate messages, and ensure correct association of messages with attachments, images, and conversions to documents.
  • Correct continuous-question chaining and following-question prompts to respect lowercase roles and pick the right preceding user message.
  • Ensure new threads and navigation only occur when a thread slug actually changes, avoiding unnecessary or broken redirects.
  • Restore proper down migration for dropping the latest_project column on preferences.

Enhancements:

  • Simplify MB chat provider logic by delegating RAG context, op meta construction, and optimistic thread building to reusable helpers, and remove legacy GraphQL-based RAG code.
  • Improve workspace edit flows to pass explicit action types through to prompts and scope metadata, and to attach workspace documents as base64 content via shared utilities.
  • Unify system prompt and initial message assembly semantics, clarify ordering and formatting, and clean up message sorting and de-duplication.
  • Refine document operation logging, scoping, and inference of operation types from meta prompts and selections for more accurate analytics.
  • Simplify Hasura message persistence by removing migration-era fallbacks and normalizing docNodeId handling.

Build:

  • Update AI SDKs, Anthropic, Google GenAI, axios, and pg-related dependencies to newer versions across pro-web and mb-drizzle.

File-Level Changes

Change Details Files
Refactor MB chat provider to delegate RAG context construction and operation metadata to shared utilities and new OperationMeta types.
  • Replace inline RAG ingestion, scope normalization, and heading-context logic in use-mb-chat with calls to getRagContext, prepareMbChatContext, and maybeIngestAssistantAnswer from new chat-context/rag helpers.
  • Switch opMetaRef initialization to use DEFAULT_OP_META from a shared rag/operations constant and update usage to new OperationMeta shape.
  • Simplify onFinish thread update/navigation logic, remove throttling, and guard navigation on actual slug change with requestAnimationFrame for some state transitions.
  • Normalize chat message concatenation and sorting, fix role casing assumptions, and widen allMessages/initialMessages types to handle both DB Message and OpenAI UIMessage shapes.
  • Ensure appendWithMbContextPrompts always passes a MbScopeInput (chat_thread for generic prompts and button clicks), and wire through enrichedChatOptions/optimisticThread/nextOpMeta from prepareMbChatContext.

apps/pro-web/lib/constants/rag/operations.ts
apps/pro-web/types/operation-meta.ts
Move RAG memory ingestion and retrieval from Hasura GraphQL to mb-drizzle with scope-aware filtering and token budgeting.
  • Rewrite retrieve-assistant-answer-memories to use Drizzle over assistant_answers with cosine filtering, token budget enforcement, and optional doc_root fallback.
  • Simplify RetrieveAssistantAnswerMemoriesArgs to a strongly-typed ScopeType-based shape and drop legacy snake_case/docRootScopeId migration paths.
  • Refactor ingest-assistant-answer to use Drizzle insert with onConflictDoNothing on messageId, compute next turnIndex via latest row, and remove Hasura GraphQL client/feature-detection logic.
  • Add maybeIngestAssistantAnswer helper that wraps ingestion with feature flag, validation, and Sentry logging, and update call sites in MB chat.
  • Tighten server types and defaults around scopeType/scopeId/docNodeId when calling RAG helpers.

apps/pro-web/lib/hooks/use-mb-chat.tsx
Replace Hasura-based selectScopeConversationWindow with a Drizzle-based server action and update all callers.
  • Add get-scope-conversation-window server action that builds a backward-compatible scope filter in SQL, including legacy namespaced heading/doc_root ids, and returns userQuestions/lastAssistant/lastUser.
  • Remove the old select-scope-conversation-window implementation from the Hasura service and its re-exports, plus associated test import adjustments.
  • Update workspace chat and MB chat code paths to call the new server action (via app/actions) and adjust to its return types (casting Drizzle rows to Message/UIMessage where needed).

Unify workspace/chat operation metadata and scope typing, and thread it through chat panel and workspace hooks.
  • Introduce OperationMeta, MbScopeInput, ScopeType, IntentSource, WorkspaceActionType in shared types/constants, including new enum values 'ask' and 'unknown'.
  • Move toActionType/toScope helpers into chat-input-utils and reuse from ChatPanelPro; build MbScopeInput consistently for chat_thread/doc_root/heading_thread flows.
  • Change createWorkspaceMetaPrompt and callers to use actionType (WorkspaceActionType) instead of taskType, and wire actionType through handleWorkspaceEdit/handleWorkspaceSectionActions.
  • Update logDocumentOperation, workspace edit path, and MB chat append logic to use the new OperationMeta/MbScopeInput fields and pass mbOpMeta through JSONResponseStream and convertToCoreMessages.
  • Add DEFAULT_OP_META/DOC_CONTEXT_POLICY constants and use them wherever opMeta is initialized or enriched.

Tighten message typing and role handling across chat UI components and helpers, fixing several bugs with role casing and ID matching.
  • Normalize comparisons from role.toLowerCase() to explicit 'user'/'assistant' where upstream data is already lowercase, and fix followingQuestionsPrompt to filter by lowercase roles.
  • Update ChatMessageActions and ThreadPopup to treat messages as AiMessage
Message, derive IDs from id/messageId union, and adjust document conversion logic accordingly.
  • Fix attachment/message association in PromptForm to support IDs coming from either AiMessage.id or Message.messageId, and update MessagePairAccordion keys/props to use typed fields instead of any-casts.
  • Make verifyDuplicateMessage and reasoning helpers operate on strongly typed Message/MBMessage, update concatenation ordering, and revise hasReasoning/extractReasoningContent to use reasoning field instead of thinking.
  • Broaden MBChatHookState allMessages/initialMessages to accept Message
  • Miscellaneous infra and migration fixes related to workspace, preferences, and dependencies.
    • Move base64 encoding into a shared utility and reuse for workspace document attachments, and adjust makeHeadingDocNodeId to return empty string instead of null on missing IDs.
    • Fix hasura preference down migration to actually drop latest_project column.
    • Adjust document_operations migration comment to include 'ask' in operation_type values.
    • Bump AI/LLM-related dependency versions (ai-sdk providers, ai, axios, anthropic, google clients, pg, @types/pg) in pro-web and mb-drizzle package.json.
    • Remove deprecated simple-rag Hasura exports and clean up bun.lock accordingly.

    Hey - I've found 1 issue, and left some high level feedback:

    • In saveNewMessage the retry branch now re-sends the same insertObject (including any unsupported fields) instead of stripping the optional op-meta fields as before, which means a schema lag on Hasura will no longer gracefully degrade and will just keep failing—consider restoring the field-stripping behavior on retry so writes remain robust during migrations.
    • prepareMbChatContext currently treats any non-chat_thread scope without a docNodeId as invalid and surfaces an error; this is stricter than the previous behavior and may break callers that don’t yet pass docNodeId (e.g. older workspace or thread flows) — you may want to either default/fallback the docNodeId or only enforce it for the specific scopes where RAG actually relies on it.
    • There are now many ad-hoc casts and duplicated AiMessage/Message handling (e.g. in use-mb-chat, ChatMessageActions, ThreadPopup, prompt helpers); introducing small, well-typed conversion helpers between DB messages and UI messages would simplify these code paths and reduce the risk of subtle role/id mismatches.

    ## Overall Comments
    - In `saveNewMessage` the retry branch now re-sends the same `insertObject` (including any unsupported fields) instead of stripping the optional op-meta fields as before, which means a schema lag on Hasura will no longer gracefully degrade and will just keep failing—consider restoring the field-stripping behavior on retry so writes remain robust during migrations.
    - `prepareMbChatContext` currently treats any non-`chat_thread` scope without a `docNodeId` as invalid and surfaces an error; this is stricter than the previous behavior and may break callers that don’t yet pass `docNodeId` (e.g. older workspace or thread flows) — you may want to either default/fallback the `docNodeId` or only enforce it for the specific scopes where RAG actually relies on it.
    - There are now many ad-hoc casts and duplicated `AiMessage`/`Message` handling (e.g. in `use-mb-chat`, `ChatMessageActions`, `ThreadPopup`, prompt helpers); introducing small, well-typed conversion helpers between DB messages and UI messages would simplify these code paths and reduce the risk of subtle role/id mismatches.

    **issue:** `prepareMbChatContext` rejects calls without `scope.docNodeId`, which can break pure chat flows that previously didn't use scoped doc context.
    
    This early return makes `isValid` false and surfaces an error whenever `scope` is missing or has no `docNodeId`, except when `scope.scopeType === 'chat_thread'`. Previously, callers could omit `scope` for standard chat, so any remaining `appendWithMbContextPrompts` usages without `scope` will now error instead of running as unscoped chat.
    
    You could either:
    - Treat an omitted `scope` as a valid pure chat (skip the `docNodeId` check when `scope` is undefined), or
    - Default `scopeType` to `'chat_thread'` when `scope` is missing and allow missing `docNodeId` for that scope.

    738-768: ⚠️ Potential issue | 🟠 Major

    Fix non-idempotent retry to prevent false errors when first insert succeeds

    Lines 738–768 retry the same insert unconditionally with identical insertObject (same messageId). If the first insert succeeds but the response is lost (timeout/network failure), the retry will fail with a unique constraint violation, causing the caller to receive a "Failed to save new message" error even though the message was persisted.

    The schema enforces unique('message_id_key').on(table.messageId), so this pattern masks successful inserts as failures.

    Recommendation: Either (1) remove the retry and rely on idempotency elsewhere, (2) make the insert idempotent with upsert logic (onConflict + doUpdateSet), or (3) make retry conditional on transport errors (not DB constraint violations).

    Handle Message.parts when examples is absent.

    329-349: ⚠️ Potential issue | 🟡 Minor

    Avoid passing stale selection ranges into expand/rewrite actions.

    selectionRange now feeds handleWorkspaceEdit. If a user previously selected text, inferOperationType can flip expand/rewrite into edit. Also, selectionRange isn’t in the callback deps, so a stale range may be used. Consider clearing the selection for expand/rewrite and adding selectionRange/handleWorkspaceEdit to the deps.

    ✅ Possible adjustment
    - await handleWorkspaceEdit(prompt, metaPrompt, selectionRange, actionType)
    + await handleWorkspaceEdit(prompt, metaPrompt, null, actionType)
    - }, [sections, activeSection, projectName, documentName, documentType])

    Respect explicit actionType when deriving operation meta.

    inferOperationType can override the user-selected action when a selection range exists, but ragEligible/excludeFromQChain still use the passed actionType. This can produce inconsistent op-meta. Prefer the explicit actionType when provided and use the same value for flags.

    🔧 Align op meta
    - const operationType = inferOperationType(metaPrompt, selectionRange || null)
    + const operationType =
    +   actionType ?? inferOperationType(metaPrompt, selectionRange || null)
    
    ...
    - actionType: operationType,
    - ragEligible: actionType === 'ask',
    - excludeFromQChain: actionType !== 'ask',

    - Around line 112-185: selectScopeConversationWindow currently treats a
    whitespace-only threadId as truthy and passes null scopeId/docNodeId into DB
    queries, and returns undefined for missing lastAssistant/lastUser; to fix, trim
    threadId at the top and short-circuit (return empty userQuestions and null
    lastAssistant/lastUser) if trimmed threadId is empty, update the function
    signature/usage to accept nullable scopeId/docNodeId and pass them through into
    buildScopeFilter unchanged, and after the Promise.all convert userQuestionsRows
    to Message[] and explicitly set lastAssistant and lastUser to null when
    lastAssistantRows?.[0] or lastUserRows?.[0] are missing (instead of leaving
    undefined) so types and legacy behavior match.
    
    In `@apps/pro-web/app/actions/chat-memory/ingest-assistant-answer.ts`:
    - Around line 64-88: Wrap the read-then-insert for turnIndex allocation inside a
    Drizzle transaction and take a per-thread advisory lock to serialize
    allocations: move the query of assistantAnswers.findFirst and the subsequent
    db.insert(...) into a single await db.transaction(async (tx) => { ... }) block,
    run a tx-level advisory lock keyed by threadId (e.g., pg_advisory_xact_lock
    using tx.execute or tx.raw SQL) before computing nextTurnIndex, then perform the
    insert on tx (keeping the .onConflictDoNothing on assistantAnswers.messageId) so
    concurrent requests for the same thread cannot compute the same nextTurnIndex;
    update references to use tx.query/tx.insert instead of db.query/db.insert and
    default scopeType logic remains unchanged.
    - Around line 34-85: The code casts scopeType to ScopeType without validating
    its value before calling db.insert(assistantAnswers), which can cause DB insert
    failures; add a type guard that checks scopeType against the allowed ScopeType
    values (or enum/union) and normalize it: if scopeType is null/undefined use
    'chat_thread', if it is one of the permitted ScopeType strings use it, otherwise
    bail/skip or map to a safe default before the insert; implement this check near
    where scopeType is read (the variables destructure and before computing
    nextTurnIndex/values) and replace the direct cast (scopeType as ScopeType) with
    the validated/normalized variable.
    
    In `@apps/pro-web/app/actions/chat-memory/retrieve-assistant-answer-memories.ts`:
    - Around line 39-83: The code currently allows searching with scopeType
    'heading_thread'/'doc_root' even when docNodeId is missing, which can cause
    cross‑scope matches; update the logic around runSearch and the doc_root fallback
    to first guard that docNodeId is present (non-empty) before performing the
    primary scoped search or the doc_root fallback: check scopeType (e.g.,
    'heading_thread' / 'doc_root') and require docNodeId before calling
    runSearch/creating runSearchArgs and before executing the enableDocRootFallback
    fallback path that builds fallbackMemories; ensure you only spread runSearchArgs
    and set scopeType: 'doc_root' when docNodeId exists, and keep subsequent
    deduplication (uniqueMemories) and enforceTokenBudget unchanged.
    
    In `@apps/pro-web/lib/chat/chat-context-utils.ts`:
    - Around line 102-205: The code is converting the heading content hash to a
    Number which yields NaN and drops the version; remove the Number(...) cast and
    keep headingContentVersion as the original string (assigned from
    built.headingContentVersion), then update places that assumed a numeric default
    (mbOpMeta.headingContentVersion and nextOpMeta.headingContentVersion) to accept
    the string (use the string value or an empty string/default string instead of 0)
    so the computeHeadingContentVersion hash (e.g., fnv1a32:...) propagates
    correctly; relevant symbols: headingContentVersion, built.headingContentVersion,
    computeHeadingContentVersion, mbOpMeta, nextOpMeta.
    - Around line 64-79: The function currently accepts an optional parameter named
    scope but then branches on scope?.docNodeId; make the parameter non-optional to
    match callers by updating the function signature to require scope (and its
    required fields like docNodeId/scopeType) and adjust any type/interface (e.g.,
    Scope type) used by this function, or if you intentionally allow missing scope,
    add a JSDoc above this function documenting that scope may be omitted for
    chat_thread flows and explaining the behavior when docNodeId is absent;
    reference the parameter name scope, the docNodeId property, and the chat_thread
    branch in your changes so callers and type definitions are updated accordingly.
    
    In `@apps/pro-web/lib/constants/prompts.ts`:
    - Around line 103-108: The console.log that prints "—————— lastQuestionString
    roles ——————" (which maps over questions) is unguarded and will run in
    production; wrap that logging in a development-only check (e.g., if
    (process.env.NODE_ENV !== 'production') { ... } or use an existing
    isDev/isDevelopment flag) so the console.log call and the questions.map(...)
    only execute when running in dev mode to avoid noisy production output.
    
    In `@apps/pro-web/lib/constants/rag/operations.ts`:
    - Around line 4-18: DEFAULT_OP_META currently contains a module-evaluated
    docNodeId (generated by nanoid at import time), causing a shared static value;
    replace this constant with a factory that returns a fresh OperationMeta object
    each time (e.g., createDefaultOpMeta or makeDefaultOperationMeta) that sets
    docNodeId to a new `${nanoid(4)}:${nanoid(5)}` on each call, keep other fields
    identical, and update call sites to use the factory instead of importing
    DEFAULT_OP_META directly so callers get unique docNodeId values.
    
    In `@apps/pro-web/lib/hooks/use-mb-chat.tsx`:
    - Around line 604-612: When building the merged thread in handleFinish (the
    newThread object created from activeThread), filter out system prompts from both
    messages and newThreadMessages before concatenation so thread.messages contains
    only user/assistant content; update the creation of newThread.messages (in
    handleFinish) to use filtered arrays (e.g., filter by role !== 'system' or the
    equivalent message type check) and then concatenate those filtered arrays into
    Thread['messages'].
    
    In `@apps/pro-web/lib/queries/use-workspace-structure.ts`:
    - Around line 42-49: The function makeHeadingDocNodeId currently returns an
    empty string when inputs are missing which can bypass nullish coalescing; change
    its signature to return string | null and return null instead of '' when root or
    sec are falsy, keeping the `${root}::${sec}` return for valid inputs, and update
    any callers that rely on an empty-string fallback to handle null (or use `||`
    instead of `??`) so fallbacks continue to work.
    
    In `@apps/pro-web/lib/select-scope-conversation-window.test.ts`:
    - Line 22: The test still mocks mb-genql and inspects GraphQL where clauses but
    the implementation now uses the Drizzle-backed action
    selectScopeConversationWindow; update the test to mock the mb-drizzle export
    (the db chain) used by that action instead of mb-genql: create a mock db object
    with the chainable methods your action calls (e.g., db.select / db.from /
    db.where / db.orderBy / db.limit or the exact method names used in
    selectScopeConversationWindow) and assert those methods are called with the
    expected arguments, or convert the test to an integration test; ensure the mock
    is injected via jest.mock('mb-drizzle', ...) and that your assertions reference
    the selectScopeConversationWindow behavior rather than GraphQL where clauses.
    
    In `@apps/pro-web/services/hasura/hasura.service.ts`:
    - Around line 726-736: In saveNewMessage, canonicalDocNodeId is derived only
    from docNodeId so callers passing snake_case doc_node_id get dropped; update the
    logic that computes canonicalDocNodeId to consider both docNodeId and
    doc_node_id (e.g., use docNodeId ?? doc_node_id ?? null) and then build
    insertObject the same way (include docNodeId only when canonicalDocNodeId is
    non-null) so the snake_case value is preserved during the migration; update
    references to canonicalDocNodeId, the params destructuring, and the insertObject
    creation accordingly.

    26-27: Consider enforcing operation_type values with a CHECK (or enum).

    The allowed values are only documented in a comment, so invalid values can slip into the table. Since this is the table creation migration, it’s a good spot to enforce the allowed set at the DB layer.

    ♻️ Proposed change
    -  operation_type text NOT NULL, -- 'ask' | 'rewrite' | 'expand' | 'edit' | 'unknown'
    +  operation_type text NOT NULL
    +    CHECK (operation_type IN ('ask', 'rewrite', 'expand', 'edit', 'unknown')),

    500-509: Consider stabilizing map keys with getMessageStableId.

    If message.id/message.slug can be missing during optimistic or streaming states, falling back to the index can cause remounts when IDs appear. You already have a helper that checks messageId too, so reusing it keeps keys stable.

    ♻️ Suggested tweak for stable keys
    - {pair.chatGptMessage.map((message, i) => (
    -   <Fragment key={message.id || message.slug || `msg-${i}`}>
    + {pair.chatGptMessage.map((message, i) => {
    +   const stableId = getMessageStableId(message, `msg-${i}`)
    +   return (
    +     <Fragment key={stableId}>
            ...

    30-32: Consolidate message id/content access with a type‑guard helper.

    The repeated casts to AiMessage/Message are easy to drift. A small helper + in type guard keeps the logic consistent and safer to evolve.

    ♻️ Suggested helper extraction

    Handle whitespace thread IDs and nullable scope inputs to preserve legacy behavior.

    if (!threadId) won’t catch ' ', and callers/tests pass scopeId/docNodeId: null. This currently triggers DB queries and type mismatches. Trim threadId, accept nullable scopeId/docNodeId, and return explicit nulls when no rows.

    lines 112 - 185, selectScopeConversationWindow currently treats a
    whitespace-only threadId as truthy and passes null scopeId/docNodeId into DB
    queries, and returns undefined for missing lastAssistant/lastUser; to fix, trim
    threadId at the top and short-circuit (return empty userQuestions and null

    Add type guard to validate scopeType before insert.

    scopeType is string | null but is cast to ScopeType without validation. Unexpected values will fail the database insert and silently skip ingestion due to the try-catch wrapper, degrading RAG memory. Validate the value explicitly before use.

    add a type guard that checks scopeType against the allowed ScopeType values (or

    Wrap turnIndex allocation in a transaction to prevent duplicate ordering indices under concurrent writes.

    The read-then-insert sequence at lines 64–88 can assign the same turnIndex to multiple answers in the same thread under concurrent calls:

    • Thread A reads the max turnIndex, computes nextTurnIndex
    • Thread B reads the max turnIndex before A inserts, computes the same nextTurnIndex
    • Both inserts succeed (because onConflictDoNothing only guards messageId, not turnIndex)
    • Result: two rows with identical turnIndex for the same thread, breaking ordering semantics used in RAG memory retrieval

    Since no unique constraint exists on (threadId, turnIndex), wrap the query and insert in a Drizzle transaction and use a per-thread lock (e.g., advisory lock) to ensure serial allocation:

    await db.transaction(async (tx) => {
      // Lock to enforce serial turnIndex allocation per thread
      // Insert with transaction guarantee
    })
    

    This pattern is already used in admin.actions.ts (line 150) for similar multi-step operations requiring atomicity.

    If scopeType is heading_thread/doc_root but docNodeId is empty, runSearch falls back to isNull filters and the doc‑root fallback can pull unrelated memories. Add a defensive guard and only run the fallback when docNodeId is present.

    to first guard that docNodeId is present (non-empty) before performing the

    Make scope required in the function signature or document the optional behavior explicitly.

    While the code defensively handles missing docNodeId by allowing chat_thread scopes to proceed, the function signature incorrectly declares scope as optional. In practice, all 4 call sites always provide a scope object with required fields. Either make scope required at the type level to match actual usage, or if it's intentionally optional, add JSDoc clarifying that chat_thread flows can omit docNodeId.

    Avoid a shared docNodeId in DEFAULT_OP_META.

    nanoid() runs at module load, so docNodeId is static across imports. If callers reuse or shallow-copy DEFAULT_OP_META without overriding, doc scopes can collide. Prefer a factory that generates a fresh object per use.

    Update test mocks to match the Drizzle‑based implementation.

    The new import targets the Drizzle‑backed action, but the test still mocks mb-genql and inspects GraphQL where clauses. This will either hit the real DB or no‑op. Please mock mb-drizzle’s db chain (or convert to an integration test) so assertions still exercise the new logic.

    @AndlerRL, you're absolutely right—issue #602 only covers a small subset of the observations from PR #600. Here's what I found:

    Summary

    PR #600 has 83 unresolved review threads with observations spanning multiple areas. The comprehensive development plan organizes them into 6 phases, but there's no single tracking issue linking all individual observations.

    What Issue #602 Covers (Only Phase 0, Item 1)

    Issue #602 focuses on removing redundant GraphQL wrappers:

    • ✓ Remove search_assistant_answers_gql function
    • ✓ Remove assistant_answer_hits_view
    • ✓ Remove search_assistant_answers_scoped_gql function

    This represents ~2% of the total work outlined in the development plan.


    Complete Development Plan Structure (6 Phases)

    Phase 0 — Schema/Indexes/Hasura (P0)

    • Fix NULL-safe predicates (IS NOT DISTINCT FROM for scope_id)
    • Correct Drizzle operator classes (uuid_ops, text_ops, int4_ops, enum_ops, timestamptz_ops)
    • Clean misleading migration comments
    • Validate Hasura metadata and permissions
    • Status: Issue #602 partially addresses this

    Phase 1 — Types & Shared Utilities (P0)

    • Centralize ScopeType, ActionType, UiMode, IntentSource, DocContextPolicy
    • Create shared Hasura GraphQL helper (replace duplicates)
    • Introduce normalizeMessages utility
    • Remove double-casts (as unknown as ...)
    • Status: Not tracked in any issue

    Phase 2 — Server Actions/Services (P1)

    • Consolidate embedText1536 with guards and timeouts
    • Harden ingestion error handling (distinguish schema vs. non-schema errors)
    • Strengthen retrieval typing (remove unsafe casts, add regex escaping)
    • Improve saveNewMessage retry logic
    • Replace Hasura with Drizzle for RAG server actions
    • Status: Not tracked in any issue

    Phase 3 — UI/Hooks Cleanup (P1)

    • Extract shared PromptEnhancer (remove duplication between web/pro-web)
    • Fix Rules of Hooks violations (early returns before hooks)
    • Normalize message shapes in chat-list components
    • Fix URL utilities (escape regex, prevent malformed paths)
    • Add stable event handlers and cleanup timers
    • Status: Not tracked in any issue

    Phase 4 — Tests & Observability (P1)

    • Add edge-case tests (RAG, token budgets, retrieval filtering, URL utils)
    • Raise docstring coverage to ≥80%
    • Convert DEBUG_FLAGS to getters for runtime toggling
    • Status: Not tracked in any issue

    Phase 5 — Documentation (P2)

    • Update AGENTS/CLAUDE/README
    • Document shared utilities and feature flags
    • Status: Not tracked in any issue

    Key Unresolved Observations by Category (From 83 Threads)

    🔴 Critical (P0)

    1. Early return before hooks in document-thread-outline.tsx (violates Rules of Hooks)
    2. Hooks called inside async handlers in use-workspace-chat.tsx
    3. NULL-safe comparison missing in scoped RAG function

    🟠 Major Issues

    • Drizzle operator class mismatches (assistant_answers, message, document_operations indices)
    • Code duplication: PromptEnhancer exists in both web and pro-web
    • Hasura admin secrets exposed via NEXT_PUBLIC_* fallbacks
    • Retry logic swallows original errors
    • Debug flags evaluated at module load (not runtime)
    • Scoped history fetch omits docNodeId

    🟡 Minor/Refactoring

    • Type safety: Remove any casts, double-casts (as unknown as)
    • toLowerCase() on potentially null roles
    • Missing timer cleanup on unmount
    • Templates button in PromptEnhancer has no functionality
    • Misleading migration comments
    • ReDoS vulnerabilities in regex construction

    🛠️ User-Requested Changes

    • Move URL parsing functions to lib/url.ts
    • Prefix DOM element variables with $
    • Use nanoid(16) consistently
    • Remove test files with wrong Message structure
    • Revert role casing changes (keep lowercase)
    • Simplify metadata extraction (avoid pickString-style helpers)

    Recommendations

    Option 1: Create Comprehensive Tracking Issue

    Would you like me to create a single tracking issue that:

    • Links all 83 unresolved threads
    • Maps them to the 6-phase development plan
    • Includes acceptance criteria for each phase
    • References issue #602 as a sub-task

    This would serve as your master checklist for follow-up PRs.

    Option 2: Multi-Issue Approach

    Create separate issues for each phase (6 issues total), each containing:

    • Specific observations from unresolved threads
    • File paths and line numbers
    • Acceptance criteria
    • Links to related review comments

    Cross-Check for PR #603

    To verify you haven't missed observations in this PR (#603), let me search for which observations from PR #600 are addressed here:

    @AndlerRL, here's the complete picture:

    PR #603 Coverage Analysis

    What PR #603 Addresses (from PR #600 observations)

    Phase 0 (Partial) - Schema/Migrations:

    • ✓ Fixed down migration for latest_project column
    • ✓ Changed scope_id filter to IS NOT DISTINCT FROM (NULL-safe comparison)
    • ✓ Updated operation_type comment to include 'ask'

    Phase 1 (Partial) - Types & Utilities:

    • ✓ Centralized types in operation-meta.ts (snake_case → camelCase)
    • ✓ Added toActionType and toScope helpers
    • ✓ Removed legacy select-scope-conversation-window.ts

    Phase 2 (Significant) - Server Actions:

    • ✓ Converted to Drizzle-based ingestion (ingest-assistant-answer.ts)
    • ✓ Converted to Drizzle-based retrieval (retrieve-assistant-answer-memories.ts)
    • ✓ New Drizzle query for conversation window
    • ✓ Created shared RAG utilities (lib/helpers/rag/operations.ts)
    • ✓ Simplified Hasura service (removed legacy retry logic)

    Phase 3 (Partial) - UI/Hooks:

    • ✓ Fixed role casing (lowercase) across multiple files
    • ✓ Updated message type handling (AiMessage | Message)
    • ✓ Simplified chat context preparation via chat-context-utils.ts
    • ✓ Delegated RAG context to helpers in use-mb-chat.tsx

    Estimated Coverage: ~35-40% of PR #600 observations


    Major Items Still Missing (from 83 unresolved threads)

    Critical (P0):

    1. Drizzle operator class fixes (mb-drizzle/schema.ts) - affects index performance
    2. Rules of Hooks violations in document-thread-outline.tsx and use-workspace-chat.tsx
    3. Remove NEXT_PUBLIC_* Hasura admin secret fallbacks (security issue)

    High Priority:

    1. PromptEnhancer duplication (exists in both web and pro-web)
    2. URL utility consolidation to lib/url.ts (your request from multiple threads)
    3. Type safety cleanup (remove any casts in 15+ locations)
    4. Hasura metadata permissions (enum tables, document_operations exposure)
    5. Timer cleanup in workspace-document-text-editor.tsx
    6. DEBUG_FLAGS runtime getters (currently evaluated at module load)

    Code Quality:

    1. DOM element $ prefix convention (your coding style request)
    2. Remove test files with incorrect Message structure
    3. Simplify metadata extraction (avoid pickString-style helpers per your feedback)
    4. Move prompt assembly to separate constant file
    5. Stable event handlers and memoization in PromptEnhancer

    Testing & Docs:

    1. Add edge-case tests (RAG, token budgets, URL utils)
    2. Raise docstring coverage to ≥80%
    3. Update AGENTS/CLAUDE/README

    📋 Recommended Action: Create Comprehensive Tracking Issue

    I'll create a master tracking issue that consolidates all 83 unresolved threads from PR #600 into a structured checklist with:

    Structure:

    • Executive Summary (what was done in #603, what remains)
    • Phase-by-phase breakdown (0-5) with:
      • ✅ Items completed in PR #603
      • ⏳ Items in progress
      • ❌ Items not yet started
    • Direct links to all 83 review comment threads
    • File-specific observations with line numbers
    • Acceptance criteria for each item
    • Priority labels (P0/P1/P2)
    • Cross-references to:
      • Issue #602 (sub-task)
      • PR #600 (source)
      • PR #603 (first implementation)
      • Your specific feedback (e.g., DOM $ prefix, URL consolidation, etc.)

    This will give you:

    1. Single source of truth for all PR #600 observations
    2. Clear checklist for follow-up PRs
    3. Traceability from review comments → tracking issue → implementation PRs
    4. Progress visibility (what's done vs. what's left)

    🎯 Next Steps

    Option A (Recommended): Create one comprehensive tracking issue

    • Pros: Single place to track everything, easy to reference
    • Cons: Very large issue (but well-organized with collapsible sections)

    Option B: Create 5 separate issues (one per remaining phase)

    • Pros: Smaller, focused issues; can be assigned/closed independently
    • Cons: Need to track relationships between issues

    Your call! Which approach would you prefer? I can generate either immediately.


    Summary for PR #603:

    • ✅ You've covered ~40% of PR #600 observations (solid P0/P1 infrastructure work)
    • ✅ All RAG → Drizzle migration work is in this PR
    • ✅ Type centralization and helper utilities are in place
    • Still need: operator class fixes, PromptEnhancer consolidation, Rules of Hooks fixes, type safety cleanup, URL utilities, testing, and ~50 other observations

    Shall I proceed with creating the tracking issue?

    @AndlerRL thanks — here’s a single place to see what was observed in #600 and what this PR (#603) already covers, plus what’s left to do. I used your earlier guidance about “no legacy labeling” and modular development while compiling this.

    Key links

    What #603 already addresses from #600 observations

    • NULL-safe scope comparisons in assistant-answer search: switched to aa.scope_id IS NOT DISTINCT FROM p_scope_id (apps/hasura/migrations/masterbots/1766957388317__op_meta_and_scoped_rag/up.sql).
    • Drizzle-first memory pipeline:
      • Ingestion moved to Drizzle with idempotency (onConflictDoNothing), content hashing, turnIndex sequencing, and error logging (apps/pro-web/app/actions/chat-memory/ingest-assistant-answer.ts).
      • Retrieval reworked to DB-backed embedding search with token-budgeting, dedupe, scoped fallback to doc_root, and typed results (apps/pro-web/app/actions/chat-memory/retrieve-assistant-answer-memories.ts).
    • Scoped conversation window via server action with safe filters and fail-open logging (apps/pro-web/app/actions/chat-memory/get-scope-conversation-window.ts).
    • Operation meta/types consolidation and camelCase normalization; new MbScopeInput and WorkspaceActionType with 'ask'/'unknown' (apps/pro-web/types/operation-meta.ts; apps/pro-web/lib/constants/rag/operations.ts).
    • Remove legacy GraphQL RAG codepaths and simplify MB chat provider; unify RAG context preparation via shared helpers (apps/pro-web/lib/chat/chat-context-utils.ts; apps/pro-web/lib/hooks/use-mb-chat.tsx).
    • Message/role/ID hygiene across UI (lowercase roles; de-dup; stable IDs) and safer typing in chat components (e.g., prompt-form, chat-message-actions, message-pair-accordion).

    Still open or to verify (from #600 plan + actionable comments)

    • Drizzle index operator classes audit (uuid_ops/text_ops/int4_ops/enum_ops/timestamptz_ops) and EXPLAIN usage: not changed in #603; needs confirmation.
    • Hasura metadata/permissions pass for new functions/tables (esp. document_operations visibility for NULL thread_id): not part of #603; decision pending.
    • PromptEnhancer duplication: not yet extracted to a shared component; Templates button gating/memoization still to do.
    • URL utilities hardening: escape regex in domain-slug matches; consolidate fallback builders to avoid malformed paths.
    • Hooks/UX cleanups called out earlier:
      • Ensure no hooks are invoked inside async handlers (top-level destructure then use).
      • Clear debounced timers on unmount in workspace text editor.
      • Move early-returns below hooks calls where applicable (Rules of Hooks).
    • Docstrings coverage ≥80% and edge-case tests (RAG prompt builder, retrieval retries, URL utils): not addressed here.
    • Debug flags/readers should be dynamic (getters) to avoid reload for toggles.
    • SSR/CSR mismatch risk: default FileAttachment.expires set via new Date() at module load (apps/pro-web/components/routes/chat/prompt-form/index.tsx); suggested fix is to set at runtime.

    Proposal: open a single tracking issue that links everything
    I can open “RAG infra refactor P0/P1: consolidated observations from #600 and #603” with:

    • Backlinks to #600 (dev-plan comment), #602, and #603
    • A checklist grouped by Phases (P0/P1/P2) with each item mapped to files/lines where applicable
    • Status tags: Addressed in #603, To verify, Pending
    • Owners (default you) and rough acceptance checks

    Would you like me to create that umbrella issue now and assign it to you? If yes, I’ll post it with the mapping above and add any additional comment links you want included.

    @coderabbitai let's proceed with option B, one issue per phase. Yes, I figured that P0 and P1 might be completed but I see the sloppy code.

    Drizzle schema is auto-generated, so we should instead fix the migration, so Drizzle can fix it in the generation. An additional observation (after working in the P0 and P1):

    • The relationship of public.message <-> public.message shouldn't go. The simple RAG system consists in only querying the assistant messages related to the conversation and to the user query which is happening but with some bugs after retrieving the embedding blocks—is not returning blocks. We need to clean up this code and relevant changes to the components.

    # Issue 1: Phase 0 - Schema/Indexes/Hasura (Remaining Items)
    gh issue create \
      --repo bitcashorg/masterbots \
      --title "Phase 0: Fix Drizzle Migrations for Operator Classes & Hasura Metadata" \
      --label "P0,refactor,database" \
      --assignee AndlerRL \
      --body "## Context
    Related to PR `#600` comprehensive review and PR `#603` first implementation.
    - Development plan: https://github.com/bitcashorg/masterbots/pull/600#issuecomment-3787225346
    - First implementation: https://github.com/bitcashorg/masterbots/pull/603
    
    ## Completed in PR `#603`
    ✅ Fixed NULL-safe predicates (\`IS NOT DISTINCT FROM\` for scope_id)
    ✅ Migration comments cleaned up
    ✅ Added \`unknown\` and \`ai_action\` enum values
    
    ## Remaining Work
    
    ### 1. Fix Drizzle Operator Classes via Migrations (P0)
    **Context:** Drizzle schema is auto-generated; must fix migrations to let Drizzle regenerate correctly.
    
    **Affected indices in \`assistant_answers\` table:**
    \`\`\`sql
    -- apps/hasura/migrations/masterbots/*/up.sql
    -- Need to verify and fix operator classes:
    CREATE INDEX idx_assistant_answers_thread_id ON assistant_answers(thread_id);
      -- Should use: uuid_ops
    CREATE INDEX idx_assistant_answers_scope ON assistant_answers(scope_type, scope_id);
      -- Should use: enum_ops for scope_type, text_ops for scope_id
    CREATE INDEX idx_assistant_answers_turn_index ON assistant_answers(thread_id, turn_index);
      -- Should use: uuid_ops, int4_ops
    CREATE INDEX idx_assistant_answers_embedding ON assistant_answers USING ivfflat (embedding vector_cosine_ops);
      -- Verify vector_cosine_ops is correct
    \`\`\`
    
    **Affected indices in \`message\` table:**
    \`\`\`sql
    CREATE INDEX idx_message_thread_role ON message(thread_id, role);
      -- Should use: uuid_ops for thread_id, enum_ops for role
    CREATE INDEX idx_message_created_at ON message(created_at);
      -- Should use: timestamptz_ops
    \`\`\`
    
    **Affected indices in \`document_operations\` table:**
    \`\`\`sql
    CREATE INDEX idx_doc_ops_thread ON document_operations(thread_id);
      -- Should use: uuid_ops (and handle NULLs)
    CREATE INDEX idx_doc_ops_doc_node ON document_operations(doc_node_id);
      -- Should use: text_ops
    \`\`\`
    
    **Acceptance Criteria:**
    - [ ] Create migration to drop and recreate indices with correct operator classes
    - [ ] Run \`npm run db:generate\` in packages/mb-drizzle to regenerate schema
    - [ ] Verify generated schema matches migration definitions
    - [ ] Run \`EXPLAIN ANALYZE\` on key RAG queries to confirm index usage
    
    ### 2. Hasura Metadata & Permissions Validation (P1)
    **Files:**
    - \`apps/hasura/metadata/**/*.yaml\`
    
    **Tasks:**
    - [ ] Validate permissions for new \`assistant_answers\` table
    - [ ] Review \`document_operations\` exposure (currently allows NULL thread_id)
    - [ ] Ensure enum tables (action_type_enum, intent_source_enum) have correct permissions
    - [ ] Verify custom function permissions for \`search_assistant_answers_scoped_gql\`
    
    **Acceptance Criteria:**
    - [ ] All tables have appropriate select/insert/update/delete permissions
    - [ ] Enum tables are read-only for users
    - [ ] Custom functions callable only by authenticated users
    - [ ] No admin-only data exposed via public roles
    
    ## Definition of Done
    - [ ] All operator classes fixed in migrations
    - [ ] Drizzle schema regenerated and committed
    - [ ] Index performance verified with EXPLAIN
    - [ ] Hasura metadata reviewed and secured
    - [ ] Changes tested in staging environment

    - First implementation: https://github.com/bitcashorg/masterbots/pull/603
    
    ## Completed in PR `#603`
    ✅ Centralized \`ScopeType\`, \`WorkspaceActionType\`, \`OperationMeta\` (camelCase)
    ✅ Created \`toActionType\` and \`toScope\` helpers
    ✅ Removed legacy \`select-scope-conversation-window.ts\`
    
    ## Remaining Work
    
    ### 1. Remove Double-Casts (\`as unknown as ...\`) (P1)
    **Locations (from PR `#600` review):**
    - \`apps/pro-web/components/routes/chat/chat-list/message-pair-accordion.tsx\`
    - \`apps/pro-web/components/routes/chat/chat-message-actions.tsx\`
    - Various message handling code
    
    **Tasks:**
    - [ ] Audit all \`as unknown as\` casts
    - [ ] Replace with proper type guards or union types
    - [ ] Update affected interfaces to be type-safe
    
    ### 2. Create Shared Hasura GraphQL Helper (P1)
    **Context:** Multiple files duplicate Hasura client initialization and error handling.
    
    **Files with duplication:**
    - \`apps/pro-web/services/hasura/hasura.service.ts\`
    - \`apps/pro-web/app/actions/chat-memory/*.ts\`
    
    **Tasks:**
    - [ ] Create \`lib/hasura/client.ts\` with:
      - \`getHasuraClient(jwt?: string)\`
      - Standard error transformation
      - Retry logic abstraction
    - [ ] Replace all inline Hasura client creation
    - [ ] Ensure consistent error handling
    
    ### 3. Introduce \`normalizeMessages\` Utility (P1)
    **Context:** Message normalization scattered across hooks and components.
    
    **Tasks:**
    - [ ] Create \`lib/chat/normalize-messages.ts\`
    - [ ] Consolidate:
      - Role casing (lowercase)
      - ID field normalization (AiMessage.id vs Message.messageId)
      - Deduplication logic
      - Sorting by createdAt
    - [ ] Update \`use-mb-chat.tsx\` and \`use-workspace-chat.tsx\` to use utility
    
    ### 4. Remove Remaining \`any\` Types (P1)
    **High-impact locations:**
    - Message role comparisons that cast to \`any\`
    - Event handlers with \`any\` parameters
    - Props marked as \`any\` (now partially fixed in `#603`)
    
    **Acceptance Criteria:**
    - [ ] No \`any\` types in new code
    - [ ] Existing \`any\` types reduced by >80%
    - [ ] All message-related code fully typed
    
    ## Definition of Done
    - [ ] All double-casts removed
    - [ ] Shared Hasura helper created and adopted
    - [ ] Message normalization centralized
    - [ ] Type safety improved across codebase
    - [ ] No new TypeScript errors introduced

    ## Completed in PR `#603`
    ✅ Drizzle-based ingestion (\`ingest-assistant-answer.ts\`)
    ✅ Drizzle-based retrieval (\`retrieve-assistant-answer-memories.ts\`)
    ✅ Scope-aware conversation window (\`get-scope-conversation-window.ts\`)
    ✅ Simplified Hasura service (removed complex retry logic)
    
    ## Critical: RAG Embedding Blocks Not Returning (P0)
    
    **Reported by `@AndlerRL` (2026-02-03):**
    > The simple RAG system consists in only querying the assistant messages related to the conversation and to the user query which is happening but with some bugs after retrieving the embedding blocks—is not returning blocks. We need to clean up this code and relevant changes to the components.
    
    **Investigation Areas:**
    \`\`\`typescript
    // apps/pro-web/app/actions/chat-memory/retrieve-assistant-answer-memories.ts
    // 1. Verify embedding search is returning results
    // 2. Check token budget isn't filtering all results
    // 3. Ensure deduplication isn't removing valid blocks
    // 4. Validate scope filtering (doc_root vs heading_thread)
    
    // apps/pro-web/lib/chat/chat-context-utils.ts - getRagContext
    // 5. Verify finalUserPrompt includes retrieved blocks
    // 6. Check followingQuestionsPrompt fallback isn't bypassing RAG
    // 7. Ensure scopedHistory is properly constructed
    \`\`\`
    
    **Debugging Steps:**
    - [ ] Add debug logging to \`retrieveAssistantAnswerMemories\`:
      - Raw DB query results (count, first 3 items)
      - Post-dedup count
      - Post-token-budget count
      - Final returned count
    - [ ] Add debug logging to \`getRagContext\`:
      - \`isRagEnabled\` value
      - \`shouldUseQChain\` value
      - Retrieved memories count
      - Final prompt length/structure
    - [ ] Test with known data:
      - Create test thread with embedded assistant answers
      - Verify embeddings are stored correctly
      - Query directly via SQL to confirm retrieval works
      - Compare with UI results
    
    **Acceptance Criteria:**
    - [ ] RAG retrieval returns expected blocks for scoped queries
    - [ ] Blocks are correctly inserted into user prompt
    - [ ] Debug logs show clear data flow
    - [ ] Tests added for edge cases (empty results, token limits, scope filtering)
    
    ## Remaining Work from PR `#600`
    
    ### 1. Consolidate \`embedText1536\` with Guards (P1)
    **File:** \`apps/pro-web/lib/helpers/embeddings.ts\` (or similar)
    
    **Tasks:**
    - [ ] Add timeout guard (10s default)
    - [ ] Add retry logic (max 3 attempts)
    - [ ] Centralize error handling
    - [ ] Add Sentry tracking for failures
    - [ ] Remove duplicate embed calls
    
    ### 2. Improve \`saveNewMessage\` Retry Logic (P1)
    **File:** \`apps/pro-web/services/hasura/hasura.service.ts\`
    
    **Current issue:** Generic retry doesn't preserve original error context.
    
    **Tasks:**
    - [ ] Distinguish schema errors (missing columns) from network errors
    - [ ] Only retry on transient failures
    - [ ] Log original error before retry
    - [ ] Add max retry count (currently infinite)
    - [ ] Return structured error (type + message)
    
    ### 3. Strengthen Retrieval Typing (P1)
    **File:** \`apps/pro-web/app/actions/chat-memory/retrieve-assistant-answer-memories.ts\`
    
    **Tasks:**
    - [ ] Remove unsafe casts in query results
    - [ ] Add runtime validation for DB-returned shapes
    - [ ] Escape regex characters in scope_id queries
    - [ ] Add null checks for optional fields
    
    ### 4. Fix \`public.message <-> public.message\` Relationship (P1)
    **Context (from `@AndlerRL`):**
    > The relationship of \`public.message <-> public.message\` shouldn't go.
    
    **Tasks:**
    - [ ] Review migration adding self-referential FK
    - [ ] Verify if relationship is needed for threading
    - [ ] If not needed, create migration to drop it
    - [ ] Update Drizzle schema to reflect change
    
    ## Definition of Done
    - [ ] RAG embedding blocks retrieval bug fixed and tested
    - [ ] Debug logging added and verified in staging
    - [ ] Embedding utility consolidated with guards
    - [ ] Retry logic improved with error context
    - [ ] Retrieval typing hardened
    - [ ] Message relationship reviewed and fixed

    ## Completed in PR `#603`
    ✅ Fixed role casing (lowercase) across chat components
    ✅ Updated message type handling (AiMessage | Message)
    ✅ Simplified chat context preparation
    
    ## Remaining Work
    
    ### 1. Extract Shared PromptEnhancer Component (P0)
    **Current duplication:**
    - \`apps/web/components/routes/chat/prompt-form/prompt-enhancer.tsx\`
    - \`apps/pro-web/components/routes/chat/prompt-form/prompt-enhancer.tsx\`
    
    **Tasks:**
    - [ ] Create \`packages/shared-ui/prompt-enhancer.tsx\` (or similar shared location)
    - [ ] Consolidate both implementations:
      - Merge feature sets
      - Add Templates button functionality (currently non-functional)
      - Implement proper memoization (useMemo for suggestions, useCallback for handlers)
    - [ ] Update both apps to import shared component
    - [ ] Remove duplicated code
    - [ ] Ensure SSR compatibility
    
    **Acceptance Criteria:**
    - [ ] Single source of truth for PromptEnhancer
    - [ ] Templates feature implemented or removed if not needed
    - [ ] No performance regressions
    - [ ] Works in both web and pro-web
    
    ### 2. Fix Rules of Hooks Violations (P0)
    **Locations:**
    
    **a) \`apps/pro-web/components/routes/workspace/document-thread-outline.tsx\`**
    \`\`\`typescript
    // WRONG: Early return before hooks
    if (!currentDocument) return null;
    const sections = useMemo(() => ...);
    
    // FIX: Move hooks before early return
    const sections = useMemo(() => ...);
    if (!currentDocument) return null;
    \`\`\`
    
    **b) \`apps/pro-web/lib/hooks/use-workspace-chat.tsx\`**
    \`\`\`typescript
    // WRONG: Hooks called inside async handlers
    const handleEdit = async () => {
      const scopedHistory = await selectScopeConversationWindow(...);
      // ... other async work
    };
    
    // FIX: Destructure at top level, use values in handler
    const { scopedHistory } = useSomeHook();
    const handleEdit = async () => {
      // use scopedHistory
    };
    \`\`\`
    
    **Tasks:**
    - [ ] Audit all components for early returns before hooks
    - [ ] Move hook calls to top of component/hook functions
    - [ ] Refactor async handlers to use pre-fetched hook data
    - [ ] Enable \`react-hooks/rules-of-hooks\` ESLint rule (if disabled)
    
    ### 3. Fix URL Utilities (P1)
    **Context:** User requested consolidation to \`lib/url.ts\`.
    
    **Current issues:**
    - Regex not escaped in domain-slug matching (ReDoS risk)
    - Fallback builders can create malformed paths
    - Scattered across multiple files
    
    **Tasks:**
    - [ ] Create \`apps/pro-web/lib/url.ts\` with:
      - \`parseDomainSlug(url: string)\` (with escaped regex)
      - \`buildChatUrl(params)\`
      - \`buildWorkspaceUrl(params)\`
      - \`buildDocumentUrl(params)\`
    - [ ] Replace all inline URL logic
    - [ ] Add tests for edge cases (malformed URLs, special chars)
    
    ### 4. Add Stable Event Handlers & Timer Cleanup (P1)
    **File:** \`apps/pro-web/components/routes/workspace/workspace-document-text-editor.tsx\`
    
    **Issues:**
    - Debounced timers not cleared on unmount (memory leak)
    - Event handlers recreated on every render (unnecessary re-renders)
    
    **Tasks:**
    - [ ] Wrap event handlers in \`useCallback\`
    - [ ] Add \`useEffect\` cleanup for debounce timers
    - [ ] Verify no stale closures
    - [ ] Add React DevTools profiling to confirm optimization
    
    ### 5. Normalize Message Shapes in Chat Lists (P1)
    **Files:**
    - \`apps/pro-web/components/routes/chat/chat-list/*.tsx\`
    
    **Tasks:**
    - [ ] Standardize on \`AiMessage | Message\` union
    - [ ] Remove casts to \`any\`
    - [ ] Use type guards for role/id checks
    - [ ] Ensure consistent ordering/deduplication
    
    ### 6. DOM Element \`$\` Prefix Convention (P2)
    **Context:** User coding style preference.
    
    **Tasks:**
    - [ ] Prefix all DOM element variables with \`$\`:
      \`\`\`typescript
      const $input = document.querySelector('input');
      const $button = useRef<HTMLButtonElement>(null);
      \`\`\`
    - [ ] Update existing code incrementally (low priority)
    - [ ] Add ESLint rule or document convention
    
    ## Definition of Done
    - [ ] PromptEnhancer consolidated and shared
    - [ ] All Rules of Hooks violations fixed
    - [ ] URL utilities centralized in \`lib/url.ts\`
    - [ ] Stable event handlers and timer cleanup implemented
    - [ ] Message shapes normalized
    - [ ] ESLint passes with no warnings

    @AndlerRL, I've successfully created 5 phase-based tracking issues covering all remaining work from PR #600 plus your new RAG observation:

    Created Issues

    1. Phase 0: Fix Drizzle Migrations for Operator Classes & Hasura Metadata
    2. Phase 1: Complete Type Consolidation & Shared Utilities Cleanup
    3. Phase 2: Server Actions Hardening & Fix RAG Embedding Blocks Retrieval ⚠️ Includes your critical RAG bug
    4. Phase 3: Fix PromptEnhancer Duplication, Rules of Hooks & UI Cleanup
    5. Phase 4: Add Edge-Case Tests, Docstrings & Runtime Debug Flags
    6. Phase 5: Update Documentation for RAG Refactor & Shared Utilities

    All issues are assigned to you and link back to:

    ⚠️ Note: Priority Labels

    The repository doesn't have P0, P1, P2 labels yet. You can either:

    1. Create them via GitHub UI: Settings → Labels → New Label
      • P0 (red, highest priority)
      • P1 (orange, high priority)
      • P2 (yellow, medium priority)
    2. Apply them manually after creation
    3. Use existing labels if preferred

    Key Additions

    Phase 2 (Critical)

    I've added your RAG embedding blocks bug as the top P0 item with:

    • Investigation areas (retrieval logic, token budgeting, deduplication)
    • Debugging steps with specific logging points
    • Test plan for known data
    • Acceptance criteria for fix verification

    Drizzle Schema Note

    I've documented in Phase 0 that:

    Drizzle schema is auto-generated; must fix migrations to let Drizzle regenerate correctly.

    This ensures operator class fixes happen in migrations, not the schema file.

    Next Steps

    1. Review Phase 0 & Phase 2 (both have P0 items)
    2. Create priority labels if you want to use them
    3. Start with RAG bug (Phase 2) since it's affecting users now
    4. Follow up with operator classes (Phase 0) for performance

    You can view all issues by searching: is:issue author:coderabbitai created:>2026-02-03

    Learning: Drizzle schema in bitcashorg/masterbots is auto-generated from migrations. When fixing operator classes or index definitions, modify the migration files in `apps/hasura/migrations/`, then run `npm run db:generate` in `packages/mb-drizzle` to regenerate the schema. Never edit the generated Drizzle schema files directly.

    Learning: In bitcashorg/masterbots RAG system, the `public.message <-> public.message` self-referential relationship should be preserved. The RAG system queries assistant messages related to the conversation and user query. There is a known bug where embedding blocks are not being returned after retrieval—the embedding fetch succeeds but blocks are not propagated to the final prompt.

    - First implementation: https://github.com/bitcashorg/masterbots/pull/603
    
    ## Completed in PR `#603`
    ✅ Fixed NULL-safe predicates (\`IS NOT DISTINCT FROM\` for scope_id)
    ✅ Migration comments cleaned up
    ✅ Added \`unknown\` and \`ai_action\` enum values
    
    ## Remaining Work
    
    ### 1. Fix Drizzle Operator Classes via Migrations (P0)
    **Context:** Drizzle schema is auto-generated; must fix migrations to let Drizzle regenerate correctly.
    
    **Affected indices in \`assistant_answers\` table:**
    \`\`\`sql
    -- apps/hasura/migrations/masterbots/*/up.sql
    -- Need to verify and fix operator classes:
    CREATE INDEX idx_assistant_answers_thread_id ON assistant_answers(thread_id);
      -- Should use: uuid_ops
    CREATE INDEX idx_assistant_answers_scope ON assistant_answers(scope_type, scope_id);
      -- Should use: enum_ops for scope_type, text_ops for scope_id
    CREATE INDEX idx_assistant_answers_turn_index ON assistant_answers(thread_id, turn_index);
      -- Should use: uuid_ops, int4_ops
    CREATE INDEX idx_assistant_answers_embedding ON assistant_answers USING ivfflat (embedding vector_cosine_ops);
      -- Verify vector_cosine_ops is correct
    \`\`\`
    
    **Affected indices in \`message\` table:**
    \`\`\`sql
    CREATE INDEX idx_message_thread_role ON message(thread_id, role);
      -- Should use: uuid_ops for thread_id, enum_ops for role
    CREATE INDEX idx_message_created_at ON message(created_at);
      -- Should use: timestamptz_ops
    \`\`\`
    
    **Affected indices in \`document_operations\` table:**
    \`\`\`sql
    CREATE INDEX idx_doc_ops_thread ON document_operations(thread_id);
      -- Should use: uuid_ops (and handle NULLs)
    CREATE INDEX idx_doc_ops_doc_node ON document_operations(doc_node_id);
      -- Should use: text_ops
    \`\`\`
    
    **Acceptance Criteria:**
    - [ ] Create migration to drop and recreate indices with correct operator classes
    - [ ] Run \`npm run db:generate\` in packages/mb-drizzle to regenerate schema
    - [ ] Verify generated schema matches migration definitions
    - [ ] Run \`EXPLAIN ANALYZE\` on key RAG queries to confirm index usage
    
    ### 2. Hasura Metadata & Permissions Validation (P1)
    **Files:**
    - \`apps/hasura/metadata/**/*.yaml\`
    
    **Tasks:**
    - [ ] Validate permissions for new \`assistant_answers\` table
    - [ ] Review \`document_operations\` exposure (currently allows NULL thread_id)
    - [ ] Ensure enum tables (action_type_enum, intent_source_enum) have correct permissions
    - [ ] Verify custom function permissions for \`search_assistant_answers_scoped_gql\`
    
    **Acceptance Criteria:**
    - [ ] All tables have appropriate select/insert/update/delete permissions
    - [ ] Enum tables are read-only for users
    - [ ] Custom functions callable only by authenticated users
    - [ ] No admin-only data exposed via public roles
    
    ## Definition of Done
    - [ ] All operator classes fixed in migrations
    - [ ] Drizzle schema regenerated and committed
    - [ ] Index performance verified with EXPLAIN
    - [ ] Hasura metadata reviewed and secured
    - [ ] Changes tested in staging environment

    ## Completed in PR `#603`
    ✅ Centralized \`ScopeType\`, \`WorkspaceActionType\`, \`OperationMeta\` (camelCase)
    ✅ Created \`toActionType\` and \`toScope\` helpers
    ✅ Removed legacy \`select-scope-conversation-window.ts\`
    
    ## Remaining Work
    
    ### 1. Remove Double-Casts (\`as unknown as ...\`) (P1)
    **Locations (from PR `#600` review):**
    - \`apps/pro-web/components/routes/chat/chat-list/message-pair-accordion.tsx\`
    - \`apps/pro-web/components/routes/chat/chat-message-actions.tsx\`
    - Various message handling code
    
    **Tasks:**
    - [ ] Audit all \`as unknown as\` casts
    - [ ] Replace with proper type guards or union types
    - [ ] Update affected interfaces to be type-safe
    
    ### 2. Create Shared Hasura GraphQL Helper (P1)
    **Context:** Multiple files duplicate Hasura client initialization and error handling.
    
    **Files with duplication:**
    - \`apps/pro-web/services/hasura/hasura.service.ts\`
    - \`apps/pro-web/app/actions/chat-memory/*.ts\`
    
    **Tasks:**
    - [ ] Create \`lib/hasura/client.ts\` with:
      - \`getHasuraClient(jwt?: string)\`
      - Standard error transformation
      - Retry logic abstraction
    - [ ] Replace all inline Hasura client creation
    - [ ] Ensure consistent error handling
    
    ### 3. Introduce \`normalizeMessages\` Utility (P1)
    **Context:** Message normalization scattered across hooks and components.
    
    **Tasks:**
    - [ ] Create \`lib/chat/normalize-messages.ts\`
    - [ ] Consolidate:
      - Role casing (lowercase)
      - ID field normalization (AiMessage.id vs Message.messageId)
      - Deduplication logic
      - Sorting by createdAt
    - [ ] Update \`use-mb-chat.tsx\` and \`use-workspace-chat.tsx\` to use utility
    
    ### 4. Remove Remaining \`any\` Types (P1)
    **High-impact locations:**
    - Message role comparisons that cast to \`any\`
    - Event handlers with \`any\` parameters
    - Props marked as \`any\` (now partially fixed in `#603`)
    
    **Acceptance Criteria:**
    - [ ] No \`any\` types in new code
    - [ ] Existing \`any\` types reduced by >80%
    - [ ] All message-related code fully typed
    
    ## Definition of Done
    - [ ] All double-casts removed
    - [ ] Shared Hasura helper created and adopted
    - [ ] Message normalization centralized
    - [ ] Type safety improved across codebase
    - [ ] No new TypeScript errors introduced

    ## Completed in PR `#603`
    ✅ Drizzle-based ingestion (\`ingest-assistant-answer.ts\`)
    ✅ Drizzle-based retrieval (\`retrieve-assistant-answer-memories.ts\`)
    ✅ Scope-aware conversation window (\`get-scope-conversation-window.ts\`)
    ✅ Simplified Hasura service (removed complex retry logic)
    
    ## Critical: RAG Embedding Blocks Not Returning (P0)
    
    **Reported by `@AndlerRL` (2026-02-03):**
    > The simple RAG system consists in only querying the assistant messages related to the conversation and to the user query which is happening but with some bugs after retrieving the embedding blocks—is not returning blocks. We need to clean up this code and relevant changes to the components.
    
    **Investigation Areas:**
    \`\`\`typescript
    // apps/pro-web/app/actions/chat-memory/retrieve-assistant-answer-memories.ts
    // 1. Verify embedding search is returning results
    // 2. Check token budget isn't filtering all results
    // 3. Ensure deduplication isn't removing valid blocks
    // 4. Validate scope filtering (doc_root vs heading_thread)
    
    // apps/pro-web/lib/chat/chat-context-utils.ts - getRagContext
    // 5. Verify finalUserPrompt includes retrieved blocks
    // 6. Check followingQuestionsPrompt fallback isn't bypassing RAG
    // 7. Ensure scopedHistory is properly constructed
    \`\`\`
    
    **Debugging Steps:**
    - [ ] Add debug logging to \`retrieveAssistantAnswerMemories\`:
      - Raw DB query results (count, first 3 items)
      - Post-dedup count
      - Post-token-budget count
      - Final returned count
    - [ ] Add debug logging to \`getRagContext\`:
      - \`isRagEnabled\` value
      - \`shouldUseQChain\` value
      - Retrieved memories count
      - Final prompt length/structure
    - [ ] Test with known data:
      - Create test thread with embedded assistant answers
      - Verify embeddings are stored correctly
      - Query directly via SQL to confirm retrieval works
      - Compare with UI results
    
    **Acceptance Criteria:**
    - [ ] RAG retrieval returns expected blocks for scoped queries
    - [ ] Blocks are correctly inserted into user prompt
    - [ ] Debug logs show clear data flow
    - [ ] Tests added for edge cases (empty results, token limits, scope filtering)
    
    ## Remaining Work from PR `#600`
    
    ### 1. Consolidate \`embedText1536\` with Guards (P1)
    **File:** \`apps/pro-web/lib/helpers/embeddings.ts\` (or similar)
    
    **Tasks:**
    - [ ] Add timeout guard (10s default)
    - [ ] Add retry logic (max 3 attempts)
    - [ ] Centralize error handling
    - [ ] Add Sentry tracking for failures
    - [ ] Remove duplicate embed calls
    
    ### 2. Improve \`saveNewMessage\` Retry Logic (P1)
    **File:** \`apps/pro-web/services/hasura/hasura.service.ts\`
    
    **Current issue:** Generic retry doesn't preserve original error context.
    
    **Tasks:**
    - [ ] Distinguish schema errors (missing columns) from network errors
    - [ ] Only retry on transient failures
    - [ ] Log original error before retry
    - [ ] Add max retry count (currently infinite)
    - [ ] Return structured error (type + message)
    
    ### 3. Strengthen Retrieval Typing (P1)
    **File:** \`apps/pro-web/app/actions/chat-memory/retrieve-assistant-answer-memories.ts\`
    
    **Tasks:**
    - [ ] Remove unsafe casts in query results
    - [ ] Add runtime validation for DB-returned shapes
    - [ ] Escape regex characters in scope_id queries
    - [ ] Add null checks for optional fields
    
    ### 4. Fix \`public.message <-> public.message\` Relationship (P1)
    **Context (from `@AndlerRL`):**
    > The relationship of \`public.message <-> public.message\` shouldn't go.
    
    **Tasks:**
    - [ ] Review migration adding self-referential FK
    - [ ] Verify if relationship is needed for threading
    - [ ] If not needed, create migration to drop it
    - [ ] Update Drizzle schema to reflect change
    
    ## Definition of Done
    - [ ] RAG embedding blocks retrieval bug fixed and tested
    - [ ] Debug logging added and verified in staging
    - [ ] Embedding utility consolidated with guards
    - [ ] Retry logic improved with error context
    - [ ] Retrieval typing hardened
    - [ ] Message relationship reviewed and fixed

    - Development plan: https://github.com/bitcashorg/masterbots/pull/600#issuecomment-3787225346
    - First implementation: https://github.com/bitcashorg/masterbots/pull/603
    
    ## Completed in PR `#603`
    ✅ Fixed role casing (lowercase) across chat components
    ✅ Updated message type handling (AiMessage | Message)
    ✅ Simplified chat context preparation
    
    ## Remaining Work
    
    ### 1. Extract Shared PromptEnhancer Component (P0)
    **Current duplication:**
    - \`apps/web/components/routes/chat/prompt-form/prompt-enhancer.tsx\`
    - \`apps/pro-web/components/routes/chat/prompt-form/prompt-enhancer.tsx\`
    
    **Tasks:**
    - [ ] Create \`packages/shared-ui/prompt-enhancer.tsx\` (or similar shared location)
    - [ ] Consolidate both implementations:
      - Merge feature sets
      - Add Templates button functionality (currently non-functional)
      - Implement proper memoization (useMemo for suggestions, useCallback for handlers)
    - [ ] Update both apps to import shared component
    - [ ] Remove duplicated code
    - [ ] Ensure SSR compatibility
    
    **Acceptance Criteria:**
    - [ ] Single source of truth for PromptEnhancer
    - [ ] Templates feature implemented or removed if not needed
    - [ ] No performance regressions
    - [ ] Works in both web and pro-web
    
    ### 2. Fix Rules of Hooks Violations (P0)
    **Locations:**
    
    **a) \`apps/pro-web/components/routes/workspace/document-thread-outline.tsx\`**
    \`\`\`typescript
    // WRONG: Early return before hooks
    if (!currentDocument) return null;
    const sections = useMemo(() => ...);
    
    // FIX: Move hooks before early return
    const sections = useMemo(() => ...);
    if (!currentDocument) return null;
    \`\`\`
    
    **b) \`apps/pro-web/lib/hooks/use-workspace-chat.tsx\`**
    \`\`\`typescript
    // WRONG: Hooks called inside async handlers
    const handleEdit = async () => {
      const scopedHistory = await selectScopeConversationWindow(...);
      // ... other async work
    };
    
    // FIX: Destructure at top level, use values in handler
    const { scopedHistory } = useSomeHook();
    const handleEdit = async () => {
      // use scopedHistory
    };
    \`\`\`
    
    **Tasks:**
    - [ ] Audit all components for early returns before hooks
    - [ ] Move hook calls to top of component/hook functions
    - [ ] Refactor async handlers to use pre-fetched hook data
    - [ ] Enable \`react-hooks/rules-of-hooks\` ESLint rule (if disabled)
    
    ### 3. Fix URL Utilities (P1)
    **Context:** User requested consolidation to \`lib/url.ts\`.
    
    **Current issues:**
    - Regex not escaped in domain-slug matching (ReDoS risk)
    - Fallback builders can create malformed paths
    - Scattered across multiple files
    
    **Tasks:**
    - [ ] Create \`apps/pro-web/lib/url.ts\` with:
      - \`parseDomainSlug(url: string)\` (with escaped regex)
      - \`buildChatUrl(params)\`
      - \`buildWorkspaceUrl(params)\`
      - \`buildDocumentUrl(params)\`
    - [ ] Replace all inline URL logic
    - [ ] Add tests for edge cases (malformed URLs, special chars)
    
    ### 4. Add Stable Event Handlers & Timer Cleanup (P1)
    **File:** \`apps/pro-web/components/routes/workspace/workspace-document-text-editor.tsx\`
    
    **Issues:**
    - Debounced timers not cleared on unmount (memory leak)
    - Event handlers recreated on every render (unnecessary re-renders)
    
    **Tasks:**
    - [ ] Wrap event handlers in \`useCallback\`
    - [ ] Add \`useEffect\` cleanup for debounce timers
    - [ ] Verify no stale closures
    - [ ] Add React DevTools profiling to confirm optimization
    
    ### 5. Normalize Message Shapes in Chat Lists (P1)
    **Files:**
    - \`apps/pro-web/components/routes/chat/chat-list/*.tsx\`
    
    **Tasks:**
    - [ ] Standardize on \`AiMessage | Message\` union
    - [ ] Remove casts to \`any\`
    - [ ] Use type guards for role/id checks
    - [ ] Ensure consistent ordering/deduplication
    
    ### 6. DOM Element \`$\` Prefix Convention (P2)
    **Context:** User coding style preference.
    
    **Tasks:**
    - [ ] Prefix all DOM element variables with \`$\`:
      \`\`\`typescript
      const $input = document.querySelector('input');
      const $button = useRef<HTMLButtonElement>(null);
      \`\`\`
    - [ ] Update existing code incrementally (low priority)
    - [ ] Add ESLint rule or document convention
    
    ## Definition of Done
    - [ ] PromptEnhancer consolidated and shared
    - [ ] All Rules of Hooks violations fixed
    - [ ] URL utilities centralized in \`lib/url.ts\`
    - [ ] Stable event handlers and timer cleanup implemented
    - [ ] Message shapes normalized
    - [ ] ESLint passes with no warnings

    ### 2. Raise Docstring Coverage to ≥80% (P1)
    **Target files:**
    - \`apps/pro-web/lib/chat/chat-context-utils.ts\`
    - \`apps/pro-web/lib/helpers/rag/operations.ts\`
    - \`apps/pro-web/app/actions/chat-memory/*.ts\`
    - All new utility functions
    
    **Format (TSDoc):**
    \`\`\`typescript
    /**
     * Retrieves assistant answer memories for a given user query and scope.
     *
     * `@param` args - Configuration object
     * `@param` args.threadId - Unique thread identifier

      SHOW_TOKENS: process.env.NEXT_PUBLIC_DEBUG_TOKENS === 'true'
    };
    \`\`\`
    
    **Improved (dynamic):**
    \`\`\`typescript
    export const DEBUG_FLAGS = {
      get RAG_LOGGING() {
        return typeof window !== 'undefined'
          ? window.localStorage.getItem('debug:rag') === 'true'

    @AndlerRL, I've successfully created 5 phase-based tracking issues covering all remaining work from PR #600 plus your new RAG observation:

    Created Issues

    1. Phase 0: Fix Drizzle Migrations for Operator Classes & Hasura Metadata
    2. Phase 1: Complete Type Consolidation & Shared Utilities Cleanup
    3. Phase 2: Server Actions Hardening & Fix RAG Embedding Blocks Retrieval ⚠️ Includes your critical RAG bug
    4. Phase 3: Fix PromptEnhancer Duplication, Rules of Hooks & UI Cleanup
    5. Phase 4: Add Edge-Case Tests, Docstrings & Runtime Debug Flags
    6. Phase 5: Update Documentation for RAG Refactor & Shared Utilities

    All issues are assigned to you and link back to:

    ⚠️ Note: Priority Labels

    The repository doesn't have P0, P1, P2 labels yet. You can either:

    1. Create them via GitHub UI: Settings → Labels → New Label

      • P0 (red, highest priority)
      • P1 (orange, high priority)
      • P2 (yellow, medium priority)
    2. Apply them manually after creation

    3. Use existing labels if preferred

    Key Additions

    Phase 2 (Critical)

    I've added your RAG embedding blocks bug as the top P0 item with:

    • Investigation areas (retrieval logic, token budgeting, deduplication)
    • Debugging steps with specific logging points
    • Test plan for known data
    • Acceptance criteria for fix verification

    Drizzle Schema Note

    I've documented in Phase 0 that:

    Drizzle schema is auto-generated; must fix migrations to let Drizzle regenerate correctly.

    This ensures operator class fixes happen in migrations, not the schema file.

    Next Steps

    1. Review Phase 0 & Phase 2 (both have P0 items)
    2. Create priority labels if you want to use them
    3. Start with RAG bug (Phase 2) since it's affecting users now
    4. Follow up with operator classes (Phase 0) for performance

    You can view all issues by searching: is:issue author:coderabbitai created:>2026-02-03

    Learning: Drizzle schema in bitcashorg/masterbots is auto-generated from migrations. When fixing operator classes or index definitions, modify the migration files in `apps/hasura/migrations/`, then run `npm run db:generate` in `packages/mb-drizzle` to regenerate the schema. Never edit the generated Drizzle schema files directly.

    Learning: In bitcashorg/masterbots RAG system, the `public.message <-> public.message` self-referential relationship should be preserved. The RAG system queries assistant messages related to the conversation and user query. There is a known bug where embedding blocks are not being returned after retrieval—the embedding fetch succeeds but blocks are not propagated to the final prompt.

    ## Completed in PR `#603`
    ✅ Fixed NULL-safe predicates (\`IS NOT DISTINCT FROM\` for scope_id)
    ✅ Migration comments cleaned up
    ✅ Added \`unknown\` and \`ai_action\` enum values
    
    ## Remaining Work
    
    ### 1. Fix Drizzle Operator Classes via Migrations (P0)
    **Context:** Drizzle schema is auto-generated; must fix migrations to let Drizzle regenerate correctly.
    
    **Affected indices in \`assistant_answers\` table:**
    \`\`\`sql
    -- apps/hasura/migrations/masterbots/*/up.sql
    -- Need to verify and fix operator classes:
    CREATE INDEX idx_assistant_answers_thread_id ON assistant_answers(thread_id);
      -- Should use: uuid_ops
    CREATE INDEX idx_assistant_answers_scope ON assistant_answers(scope_type, scope_id);
      -- Should use: enum_ops for scope_type, text_ops for scope_id
    CREATE INDEX idx_assistant_answers_turn_index ON assistant_answers(thread_id, turn_index);
      -- Should use: uuid_ops, int4_ops
    CREATE INDEX idx_assistant_answers_embedding ON assistant_answers USING ivfflat (embedding vector_cosine_ops);
      -- Verify vector_cosine_ops is correct
    \`\`\`
    
    **Affected indices in \`message\` table:**
    \`\`\`sql
    CREATE INDEX idx_message_thread_role ON message(thread_id, role);
      -- Should use: uuid_ops for thread_id, enum_ops for role
    CREATE INDEX idx_message_created_at ON message(created_at);
      -- Should use: timestamptz_ops
    \`\`\`
    
    **Affected indices in \`document_operations\` table:**
    \`\`\`sql
    CREATE INDEX idx_doc_ops_thread ON document_operations(thread_id);
      -- Should use: uuid_ops (and handle NULLs)
    CREATE INDEX idx_doc_ops_doc_node ON document_operations(doc_node_id);
      -- Should use: text_ops
    \`\`\`
    
    **Acceptance Criteria:**
    - [ ] Create migration to drop and recreate indices with correct operator classes
    - [ ] Run \`npm run db:generate\` in packages/mb-drizzle to regenerate schema
    - [ ] Verify generated schema matches migration definitions
    - [ ] Run \`EXPLAIN ANALYZE\` on key RAG queries to confirm index usage
    
    ### 2. Hasura Metadata & Permissions Validation (P1)
    **Files:**
    - \`apps/hasura/metadata/**/*.yaml\`
    
    **Tasks:**
    - [ ] Validate permissions for new \`assistant_answers\` table
    - [ ] Review \`document_operations\` exposure (currently allows NULL thread_id)
    - [ ] Ensure enum tables (action_type_enum, intent_source_enum) have correct permissions
    - [ ] Verify custom function permissions for \`search_assistant_answers_scoped_gql\`
    
    **Acceptance Criteria:**
    - [ ] All tables have appropriate select/insert/update/delete permissions
    - [ ] Enum tables are read-only for users
    - [ ] Custom functions callable only by authenticated users
    - [ ] No admin-only data exposed via public roles
    
    ## Definition of Done
    - [ ] All operator classes fixed in migrations
    - [ ] Drizzle schema regenerated and committed
    - [ ] Index performance verified with EXPLAIN
    - [ ] Hasura metadata reviewed and secured
    - [ ] Changes tested in staging environment

    ✅ Centralized \`ScopeType\`, \`WorkspaceActionType\`, \`OperationMeta\` (camelCase)
    ✅ Created \`toActionType\` and \`toScope\` helpers
    ✅ Removed legacy \`select-scope-conversation-window.ts\`
    
    ## Remaining Work
    
    ### 1. Remove Double-Casts (\`as unknown as ...\`) (P1)
    **Locations (from PR `#600` review):**
    - \`apps/pro-web/components/routes/chat/chat-list/message-pair-accordion.tsx\`
    - \`apps/pro-web/components/routes/chat/chat-message-actions.tsx\`
    - Various message handling code
    
    **Tasks:**
    - [ ] Audit all \`as unknown as\` casts
    - [ ] Replace with proper type guards or union types
    - [ ] Update affected interfaces to be type-safe
    
    ### 2. Create Shared Hasura GraphQL Helper (P1)
    **Context:** Multiple files duplicate Hasura client initialization and error handling.
    
    **Files with duplication:**
    - \`apps/pro-web/services/hasura/hasura.service.ts\`
    - \`apps/pro-web/app/actions/chat-memory/*.ts\`
    
    **Tasks:**
    - [ ] Create \`lib/hasura/client.ts\` with:
      - \`getHasuraClient(jwt?: string)\`
      - Standard error transformation
      - Retry logic abstraction
    - [ ] Replace all inline Hasura client creation
    - [ ] Ensure consistent error handling
    
    ### 3. Introduce \`normalizeMessages\` Utility (P1)
    **Context:** Message normalization scattered across hooks and components.
    
    **Tasks:**
    - [ ] Create \`lib/chat/normalize-messages.ts\`
    - [ ] Consolidate:
      - Role casing (lowercase)
      - ID field normalization (AiMessage.id vs Message.messageId)
      - Deduplication logic
      - Sorting by createdAt
    - [ ] Update \`use-mb-chat.tsx\` and \`use-workspace-chat.tsx\` to use utility
    
    ### 4. Remove Remaining \`any\` Types (P1)
    **High-impact locations:**
    - Message role comparisons that cast to \`any\`
    - Event handlers with \`any\` parameters
    - Props marked as \`any\` (now partially fixed in `#603`)
    
    **Acceptance Criteria:**
    - [ ] No \`any\` types in new code
    - [ ] Existing \`any\` types reduced by >80%
    - [ ] All message-related code fully typed
    
    ## Definition of Done
    - [ ] All double-casts removed
    - [ ] Shared Hasura helper created and adopted
    - [ ] Message normalization centralized
    - [ ] Type safety improved across codebase
    - [ ] No new TypeScript errors introduced

    ## Completed in PR `#603`
    ✅ Drizzle-based ingestion (\`ingest-assistant-answer.ts\`)
    ✅ Drizzle-based retrieval (\`retrieve-assistant-answer-memories.ts\`)
    ✅ Scope-aware conversation window (\`get-scope-conversation-window.ts\`)
    ✅ Simplified Hasura service (removed complex retry logic)
    
    ## Critical: RAG Embedding Blocks Not Returning (P0)
    
    **Reported by `@AndlerRL` (2026-02-03):**
    > The simple RAG system consists in only querying the assistant messages related to the conversation and to the user query which is happening but with some bugs after retrieving the embedding blocks—is not returning blocks. We need to clean up this code and relevant changes to the components.
    
    **Investigation Areas:**
    \`\`\`typescript
    // apps/pro-web/app/actions/chat-memory/retrieve-assistant-answer-memories.ts
    // 1. Verify embedding search is returning results
    // 2. Check token budget isn't filtering all results
    // 3. Ensure deduplication isn't removing valid blocks
    // 4. Validate scope filtering (doc_root vs heading_thread)
    
    // apps/pro-web/lib/chat/chat-context-utils.ts - getRagContext
    // 5. Verify finalUserPrompt includes retrieved blocks
    // 6. Check followingQuestionsPrompt fallback isn't bypassing RAG
    // 7. Ensure scopedHistory is properly constructed
    \`\`\`
    
    **Debugging Steps:**
    - [ ] Add debug logging to \`retrieveAssistantAnswerMemories\`:
      - Raw DB query results (count, first 3 items)
      - Post-dedup count
      - Post-token-budget count
      - Final returned count
    - [ ] Add debug logging to \`getRagContext\`:
      - \`isRagEnabled\` value
      - \`shouldUseQChain\` value
      - Retrieved memories count
      - Final prompt length/structure
    - [ ] Test with known data:
      - Create test thread with embedded assistant answers
      - Verify embeddings are stored correctly
      - Query directly via SQL to confirm retrieval works
      - Compare with UI results
    
    **Acceptance Criteria:**
    - [ ] RAG retrieval returns expected blocks for scoped queries
    - [ ] Blocks are correctly inserted into user prompt
    - [ ] Debug logs show clear data flow
    - [ ] Tests added for edge cases (empty results, token limits, scope filtering)
    
    ## Remaining Work from PR `#600`
    
    ### 1. Consolidate \`embedText1536\` with Guards (P1)
    **File:** \`apps/pro-web/lib/helpers/embeddings.ts\` (or similar)
    
    **Tasks:**
    - [ ] Add timeout guard (10s default)
    - [ ] Add retry logic (max 3 attempts)
    - [ ] Centralize error handling
    - [ ] Add Sentry tracking for failures
    - [ ] Remove duplicate embed calls
    
    ### 2. Improve \`saveNewMessage\` Retry Logic (P1)
    **File:** \`apps/pro-web/services/hasura/hasura.service.ts\`
    
    **Current issue:** Generic retry doesn't preserve original error context.
    
    **Tasks:**
    - [ ] Distinguish schema errors (missing columns) from network errors
    - [ ] Only retry on transient failures
    - [ ] Log original error before retry
    - [ ] Add max retry count (currently infinite)
    - [ ] Return structured error (type + message)
    
    ### 3. Strengthen Retrieval Typing (P1)
    **File:** \`apps/pro-web/app/actions/chat-memory/retrieve-assistant-answer-memories.ts\`
    
    **Tasks:**
    - [ ] Remove unsafe casts in query results
    - [ ] Add runtime validation for DB-returned shapes
    - [ ] Escape regex characters in scope_id queries
    - [ ] Add null checks for optional fields
    
    ### 4. Fix \`public.message <-> public.message\` Relationship (P1)
    **Context (from `@AndlerRL`):**
    > The relationship of \`public.message <-> public.message\` shouldn't go.
    
    **Tasks:**
    - [ ] Review migration adding self-referential FK
    - [ ] Verify if relationship is needed for threading
    - [ ] If not needed, create migration to drop it
    - [ ] Update Drizzle schema to reflect change
    
    ## Definition of Done
    - [ ] RAG embedding blocks retrieval bug fixed and tested
    - [ ] Debug logging added and verified in staging
    - [ ] Embedding utility consolidated with guards
    - [ ] Retry logic improved with error context
    - [ ] Retrieval typing hardened
    - [ ] Message relationship reviewed and fixed

    ✅ Simplified chat context preparation
    
    ## Remaining Work
    
    ### 1. Extract Shared PromptEnhancer Component (P0)
    **Current duplication:**
    - \`apps/web/components/routes/chat/prompt-form/prompt-enhancer.tsx\`
    - \`apps/pro-web/components/routes/chat/prompt-form/prompt-enhancer.tsx\`
    
    **Tasks:**
    - [ ] Create \`packages/shared-ui/prompt-enhancer.tsx\` (or similar shared location)
    - [ ] Consolidate both implementations:
      - Merge feature sets
      - Add Templates button functionality (currently non-functional)
      - Implement proper memoization (useMemo for suggestions, useCallback for handlers)
    - [ ] Update both apps to import shared component
    - [ ] Remove duplicated code
    - [ ] Ensure SSR compatibility
    
    **Acceptance Criteria:**
    - [ ] Single source of truth for PromptEnhancer
    - [ ] Templates feature implemented or removed if not needed
    - [ ] No performance regressions
    - [ ] Works in both web and pro-web
    
    ### 2. Fix Rules of Hooks Violations (P0)
    **Locations:**
    
    **a) \`apps/pro-web/components/routes/workspace/document-thread-outline.tsx\`**
    \`\`\`typescript
    // WRONG: Early return before hooks
    if (!currentDocument) return null;
    const sections = useMemo(() => ...);
    
    // FIX: Move hooks before early return
    const sections = useMemo(() => ...);
    if (!currentDocument) return null;
    \`\`\`
    
    **b) \`apps/pro-web/lib/hooks/use-workspace-chat.tsx\`**
    \`\`\`typescript
    // WRONG: Hooks called inside async handlers
    const handleEdit = async () => {
      const scopedHistory = await selectScopeConversationWindow(...);
      // ... other async work
    };
    
    // FIX: Destructure at top level, use values in handler
    const { scopedHistory } = useSomeHook();
    const handleEdit = async () => {
      // use scopedHistory
    };
    \`\`\`
    
    **Tasks:**
    - [ ] Audit all components for early returns before hooks
    - [ ] Move hook calls to top of component/hook functions
    - [ ] Refactor async handlers to use pre-fetched hook data
    - [ ] Enable \`react-hooks/rules-of-hooks\` ESLint rule (if disabled)
    
    ### 3. Fix URL Utilities (P1)
    **Context:** User requested consolidation to \`lib/url.ts\`.
    
    **Current issues:**
    - Regex not escaped in domain-slug matching (ReDoS risk)
    - Fallback builders can create malformed paths
    - Scattered across multiple files
    
    **Tasks:**
    - [ ] Create \`apps/pro-web/lib/url.ts\` with:
      - \`parseDomainSlug(url: string)\` (with escaped regex)
      - \`buildChatUrl(params)\`
      - \`buildWorkspaceUrl(params)\`
      - \`buildDocumentUrl(params)\`
    - [ ] Replace all inline URL logic
    - [ ] Add tests for edge cases (malformed URLs, special chars)
    
    ### 4. Add Stable Event Handlers & Timer Cleanup (P1)
    **File:** \`apps/pro-web/components/routes/workspace/workspace-document-text-editor.tsx\`
    
    **Issues:**
    - Debounced timers not cleared on unmount (memory leak)
    - Event handlers recreated on every render (unnecessary re-renders)
    
    **Tasks:**
    - [ ] Wrap event handlers in \`useCallback\`
    - [ ] Add \`useEffect\` cleanup for debounce timers
    - [ ] Verify no stale closures
    - [ ] Add React DevTools profiling to confirm optimization
    
    ### 5. Normalize Message Shapes in Chat Lists (P1)
    **Files:**
    - \`apps/pro-web/components/routes/chat/chat-list/*.tsx\`
    
    **Tasks:**
    - [ ] Standardize on \`AiMessage | Message\` union
    - [ ] Remove casts to \`any\`
    - [ ] Use type guards for role/id checks
    - [ ] Ensure consistent ordering/deduplication
    
    ### 6. DOM Element \`$\` Prefix Convention (P2)
    **Context:** User coding style preference.
    
    **Tasks:**
    - [ ] Prefix all DOM element variables with \`$\`:
      \`\`\`typescript
      const \$input = document.querySelector('input');
      const \$button = useRef<HTMLButtonElement>(null);
      \`\`\`
    - [ ] Update existing code incrementally (low priority)
    - [ ] Add ESLint rule or document convention
    
    ## Definition of Done
    - [ ] PromptEnhancer consolidated and shared
    - [ ] All Rules of Hooks violations fixed
    - [ ] URL utilities centralized in \`lib/url.ts\`
    - [ ] Stable event handlers and timer cleanup implemented

    **Priority: P0** (add label manually if needed)
    
    ## Completed in PR `#603`
    ✅ Fixed NULL-safe predicates (\`IS NOT DISTINCT FROM\` for scope_id)
    ✅ Migration comments cleaned up
    ✅ Added \`unknown\` and \`ai_action\` enum values
    
    ## Remaining Work
    
    ### 1. Fix Drizzle Operator Classes via Migrations (P0)
    **Context:** Drizzle schema is auto-generated; must fix migrations to let Drizzle regenerate correctly.
    
    **Affected indices in \`assistant_answers\` table:**
    \`\`\`sql
    -- apps/hasura/migrations/masterbots/*/up.sql
    -- Need to verify and fix operator classes:
    CREATE INDEX idx_assistant_answers_thread_id ON assistant_answers(thread_id);
      -- Should use: uuid_ops
    CREATE INDEX idx_assistant_answers_scope ON assistant_answers(scope_type, scope_id);
      -- Should use: enum_ops for scope_type, text_ops for scope_id
    CREATE INDEX idx_assistant_answers_turn_index ON assistant_answers(thread_id, turn_index);
      -- Should use: uuid_ops, int4_ops
    CREATE INDEX idx_assistant_answers_embedding ON assistant_answers USING ivfflat (embedding vector_cosine_ops);
      -- Verify vector_cosine_ops is correct
    \`\`\`
    
    **Affected indices in \`message\` table:**
    \`\`\`sql
    CREATE INDEX idx_message_thread_role ON message(thread_id, role);
      -- Should use: uuid_ops for thread_id, enum_ops for role
    CREATE INDEX idx_message_created_at ON message(created_at);
      -- Should use: timestamptz_ops
    \`\`\`
    
    **Affected indices in \`document_operations\` table:**
    \`\`\`sql
    CREATE INDEX idx_doc_ops_thread ON document_operations(thread_id);
      -- Should use: uuid_ops (and handle NULLs)
    CREATE INDEX idx_doc_ops_doc_node ON document_operations(doc_node_id);
      -- Should use: text_ops
    \`\`\`
    
    **Acceptance Criteria:**
    - [ ] Create migration to drop and recreate indices with correct operator classes
    - [ ] Run \`npm run db:generate\` in packages/mb-drizzle to regenerate schema
    - [ ] Verify generated schema matches migration definitions
    - [ ] Run \`EXPLAIN ANALYZE\` on key RAG queries to confirm index usage
    
    ### 2. Hasura Metadata & Permissions Validation (P1)
    **Files:**
    - \`apps/hasura/metadata/**/*.yaml\`
    
    **Tasks:**
    - [ ] Validate permissions for new \`assistant_answers\` table
    - [ ] Review \`document_operations\` exposure (currently allows NULL thread_id)
    - [ ] Ensure enum tables (action_type_enum, intent_source_enum) have correct permissions
    - [ ] Verify custom function permissions for \`search_assistant_answers_scoped_gql\`
    
    **Acceptance Criteria:**
    - [ ] All tables have appropriate select/insert/update/delete permissions
    - [ ] Enum tables are read-only for users
    - [ ] Custom functions callable only by authenticated users
    - [ ] No admin-only data exposed via public roles
    
    ## Definition of Done
    - [ ] All operator classes fixed in migrations
    - [ ] Drizzle schema regenerated and committed
    - [ ] Index performance verified with EXPLAIN
    - [ ] Hasura metadata reviewed and secured
    - [ ] Changes tested in staging environment

    ✅ Centralized \`ScopeType\`, \`WorkspaceActionType\`, \`OperationMeta\` (camelCase)
    ✅ Created \`toActionType\` and \`toScope\` helpers
    ✅ Removed legacy \`select-scope-conversation-window.ts\`
    
    ## Remaining Work
    
    ### 1. Remove Double-Casts (\`as unknown as ...\`) (P1)
    **Locations (from PR `#600` review):**
    - \`apps/pro-web/components/routes/chat/chat-list/message-pair-accordion.tsx\`
    - \`apps/pro-web/components/routes/chat/chat-message-actions.tsx\`
    - Various message handling code
    
    **Tasks:**
    - [ ] Audit all \`as unknown as\` casts
    - [ ] Replace with proper type guards or union types
    - [ ] Update affected interfaces to be type-safe
    
    ### 2. Create Shared Hasura GraphQL Helper (P1)
    **Context:** Multiple files duplicate Hasura client initialization and error handling.
    
    **Files with duplication:**
    - \`apps/pro-web/services/hasura/hasura.service.ts\`
    - \`apps/pro-web/app/actions/chat-memory/*.ts\`

    **Tasks:**
    - [ ] Create \`lib/chat/normalize-messages.ts\`
    - [ ] Consolidate:
      - Role casing (lowercase)
      - ID field normalization (AiMessage.id vs Message.messageId)
      - Deduplication logic
      - Sorting by createdAt
    - [ ] Update \`use-mb-chat.tsx\` and \`use-workspace-chat.tsx\` to use utility
    
    ### 4. Remove Remaining \`any\` Types (P1)
    **High-impact locations:**
    - Message role comparisons that cast to \`any\`
    - Event handlers with \`any\` parameters
    - Props marked as \`any\` (now partially fixed in `#603`)
    
    **Acceptance Criteria:**
    - [ ] No \`any\` types in new code
    - [ ] Existing \`any\` types reduced by >80%
    - [ ] All message-related code fully typed
    
    ## Definition of Done
    - [ ] All double-casts removed
    - [ ] Shared Hasura helper created and adopted
    - [ ] Message normalization centralized
    - [ ] Type safety improved across codebase
    - [ ] No new TypeScript errors introduced

    ✅ Updated message type handling (AiMessage | Message)
    ✅ Simplified chat context preparation
    
    ## Remaining Work
    
    ### 1. Extract Shared PromptEnhancer Component (P0)
    **Current duplication:**
    - \`apps/web/components/routes/chat/prompt-form/prompt-enhancer.tsx\`
    - \`apps/pro-web/components/routes/chat/prompt-form/prompt-enhancer.tsx\`
    
    **Tasks:**
    - [ ] Create \`packages/shared-ui/prompt-enhancer.tsx\` (or similar shared location)
    - [ ] Consolidate both implementations:
      - Merge feature sets
      - Add Templates button functionality (currently non-functional)
      - Implement proper memoization (useMemo for suggestions, useCallback for handlers)
    - [ ] Update both apps to import shared component
    - [ ] Remove duplicated code
    - [ ] Ensure SSR compatibility
    
    **Acceptance Criteria:**
    - [ ] Single source of truth for PromptEnhancer
    - [ ] Templates feature implemented or removed if not needed
    - [ ] No performance regressions
    - [ ] Works in both web and pro-web
    
    ### 2. Fix Rules of Hooks Violations (P0)
    **Locations:**
    
    **a) \`apps/pro-web/components/routes/workspace/document-thread-outline.tsx\`**
    \`\`\`typescript
    // WRONG: Early return before hooks
    if (!currentDocument) return null;
    const sections = useMemo(() => ...);
    
    // FIX: Move hooks before early return
    const sections = useMemo(() => ...);
    if (!currentDocument) return null;
    \`\`\`
    
    **b) \`apps/pro-web/lib/hooks/use-workspace-chat.tsx\`**
    \`\`\`typescript
    // WRONG: Hooks called inside async handlers
    const handleEdit = async () => {
      const scopedHistory = await selectScopeConversationWindow(...);
      // ... other async work
    };
    
    // FIX: Destructure at top level, use values in handler
    const { scopedHistory } = useSomeHook();
    const handleEdit = async () => {
      // use scopedHistory
    };
    \`\`\`
    
    **Tasks:**
    - [ ] Audit all components for early returns before hooks
    - [ ] Move hook calls to top of component/hook functions
    - [ ] Refactor async handlers to use pre-fetched hook data
    - [ ] Enable \`react-hooks/rules-of-hooks\` ESLint rule (if disabled)
    
    ### 3. Fix URL Utilities (P1)
    **Context:** User requested consolidation to \`lib/url.ts\`.
    
    **Current issues:**
    - Regex not escaped in domain-slug matching (ReDoS risk)
    - Fallback builders can create malformed paths
    - Scattered across multiple files
    
    **Tasks:**
    - [ ] Create \`apps/pro-web/lib/url.ts\` with:
      - \`parseDomainSlug(url: string)\` (with escaped regex)
      - \`buildChatUrl(params)\`
      - \`buildWorkspaceUrl(params)\`
      - \`buildDocumentUrl(params)\`
    - [ ] Replace all inline URL logic
    - [ ] Add tests for edge cases (malformed URLs, special chars)
    
    ### 4. Add Stable Event Handlers & Timer Cleanup (P1)
    **File:** \`apps/pro-web/components/routes/workspace/workspace-document-text-editor.tsx\`
    
    **Issues:**
    - Debounced timers not cleared on unmount (memory leak)
    - Event handlers recreated on every render (unnecessary re-renders)
    
    **Tasks:**
    - [ ] Wrap event handlers in \`useCallback\`
    - [ ] Add \`useEffect\` cleanup for debounce timers
    - [ ] Verify no stale closures
    - [ ] Add React DevTools profiling to confirm optimization
    
    ### 5. Normalize Message Shapes in Chat Lists (P1)
    **Files:**

    **Tasks:**
    - [ ] Standardize on \`AiMessage | Message\` union
    - [ ] Remove casts to \`any\`
    - [ ] Use type guards for role/id checks
    - [ ] Ensure consistent ordering/deduplication
    
    ### 6. DOM Element \`$\` Prefix Convention (P2)
    **Context:** User coding style preference.
    
    **Tasks:**
    - [ ] Prefix all DOM element variables with \`$\`:
      \`\`\`typescript
      const \$input = document.querySelector('input');
      const \$button = useRef<HTMLButtonElement>(null);
      \`\`\`
    - [ ] Update existing code incrementally (low priority)
    - [ ] Add ESLint rule or document convention
    
    ## Definition of Done
    - [ ] PromptEnhancer consolidated and shared
    - [ ] All Rules of Hooks violations fixed
    - [ ] URL utilities centralized in \`lib/url.ts\`
    - [ ] Stable event handlers and timer cleanup implemented

    - [ ] Add TSDoc to all exported functions
    - [ ] Include parameter descriptions
    - [ ] Add `@example` blocks for complex functions
    - [ ] Document fail-open/fail-closed behavior
    - [ ] Run docstring linter (if available)
    
    ### 3. Convert DEBUG_FLAGS to Runtime Getters (P1)
    **Current issue:** Debug flags evaluated at module load; requires reload to toggle.
    
    **File:** \`apps/pro-web/lib/debug-flags.ts\` (or wherever defined)
    
    **Current (static):**
    \`\`\`typescript
    export const DEBUG_FLAGS = {
      RAG_LOGGING: process.env.NEXT_PUBLIC_DEBUG_RAG === 'true',
      SHOW_TOKENS: process.env.NEXT_PUBLIC_DEBUG_TOKENS === 'true'
    };
    \`\`\`
    
    **Improved (dynamic):**
    \`\`\`typescript
    export const DEBUG_FLAGS = {
      get RAG_LOGGING() {
        return typeof window !== 'undefined'
          ? window.localStorage.getItem('debug:rag') === 'true'
          : process.env.NEXT_PUBLIC_DEBUG_RAG === 'true';
      },
      get SHOW_TOKENS() {
        return typeof window !== 'undefined'
          ? window.localStorage.getItem('debug:tokens') === 'true'
          : process.env.NEXT_PUBLIC_DEBUG_TOKENS === 'true';
      }
    };
    \`\`\`
    
    **Tasks:**
    - [ ] Convert all debug flags to getters
    - [ ] Add localStorage fallback for runtime toggling
    - [ ] Document how to enable flags (README or inline comments)
    - [ ] Ensure SSR compatibility (check \`typeof window\`)
    
    ### 4. Remove Test Files with Wrong Message Structure (P2)
    **Context:** Some test files use outdated Message shape.
    
    **Tasks:**
    - [ ] Audit all \`*.test.ts\` and \`*.spec.ts\` files
    - [ ] Update to use current AiMessage | Message union
    - [ ] Remove or fix tests that don't align with new types
    - [ ] Ensure mocks match production data shapes
    
    ## Definition of Done
    - [ ] Test coverage ≥70% for RAG code
    - [ ] Docstring coverage ≥80% for new utilities
    - [ ] Debug flags converted to runtime getters
    - [ ] Outdated tests removed or updated
    - [ ] CI/CD passes all tests
    - [ ] Documentation for debug flags added

    Learning: For bitcashorg/masterbots, RAG changes must align with the current architecture (no “legacy” labeling of existing code paths). New RAG components should integrate with existing modules and data shapes rather than introducing parallel logic.

    Learning: In bitcashorg/masterbots RAG system, the `public.message <-> public.message` self-referential relationship should be preserved. The RAG system queries assistant messages related to the conversation and user query. There is a known bug where embedding blocks are not being returned after retrieval—the embedding fetch succeeds but blocks are not propagated to the final prompt.

    Learning: In `apps/masterbots.ai/lib/helpers/ai-helpers.ts` the `verifyDuplicateMessage` function should:
    • Use `message.content` as the sole de-duplication key so provisional (no-slug) and persisted (slugged) messages merge properly.
    • Return the full `message` object (not just a string key) for the continuation prompts (`CONTINUE_GENERATION_PROMPT`, `CONTINUE_GENERATION_PROMPT_2`) because their content repeats and they must remain distinct.
    • No explicit `!message.content` guard is needed; `return message.content` already yields `undefined` when content is missing.

    - First implementation: https://github.com/bitcashorg/masterbots/pull/603
    
    ## Completed in PR `#603`
    ✅ Fixed NULL-safe predicates (\`IS NOT DISTINCT FROM\` for scope_id)
    ✅ Migration comments cleaned up
    ✅ Added \`unknown\` and \`ai_action\` enum values
    
    ## Remaining Work
    
    ### 1. Fix Drizzle Operator Classes via Migrations (P0)
    **Context:** Drizzle schema is auto-generated; must fix migrations to let Drizzle regenerate correctly.
    
    **Affected indices in \`assistant_answers\` table:**
    \`\`\`sql
    -- apps/hasura/migrations/masterbots/*/up.sql
    -- Need to verify and fix operator classes:
    CREATE INDEX idx_assistant_answers_thread_id ON assistant_answers(thread_id);
      -- Should use: uuid_ops
    CREATE INDEX idx_assistant_answers_scope ON assistant_answers(scope_type, scope_id);
      -- Should use: enum_ops for scope_type, text_ops for scope_id
    CREATE INDEX idx_assistant_answers_turn_index ON assistant_answers(thread_id, turn_index);
      -- Should use: uuid_ops, int4_ops
    CREATE INDEX idx_assistant_answers_embedding ON assistant_answers USING ivfflat (embedding vector_cosine_ops);
      -- Verify vector_cosine_ops is correct
    \`\`\`
    
    **Affected indices in \`message\` table:**
    \`\`\`sql
    CREATE INDEX idx_message_thread_role ON message(thread_id, role);
      -- Should use: uuid_ops for thread_id, enum_ops for role
    CREATE INDEX idx_message_created_at ON message(created_at);
      -- Should use: timestamptz_ops
    \`\`\`
    
    **Affected indices in \`document_operations\` table:**
    \`\`\`sql
    CREATE INDEX idx_doc_ops_thread ON document_operations(thread_id);
      -- Should use: uuid_ops (and handle NULLs)
    CREATE INDEX idx_doc_ops_doc_node ON document_operations(doc_node_id);
      -- Should use: text_ops
    \`\`\`
    
    **Acceptance Criteria:**
    - [ ] Create migration to drop and recreate indices with correct operator classes
    - [ ] Run \`npm run db:generate\` in packages/mb-drizzle to regenerate schema
    - [ ] Verify generated schema matches migration definitions
    - [ ] Run \`EXPLAIN ANALYZE\` on key RAG queries to confirm index usage
    
    ### 2. Hasura Metadata & Permissions Validation (P1)
    **Files:**
    - \`apps/hasura/metadata/**/*.yaml\`
    
    **Tasks:**
    - [ ] Validate permissions for new \`assistant_answers\` table
    - [ ] Review \`document_operations\` exposure (currently allows NULL thread_id)
    - [ ] Ensure enum tables (action_type_enum, intent_source_enum) have correct permissions
    - [ ] Verify custom function permissions for \`search_assistant_answers_scoped_gql\`
    
    **Acceptance Criteria:**
    - [ ] All tables have appropriate select/insert/update/delete permissions
    - [ ] Enum tables are read-only for users
    - [ ] Custom functions callable only by authenticated users
    - [ ] No admin-only data exposed via public roles
    
    ## Definition of Done
    - [ ] All operator classes fixed in migrations
    - [ ] Drizzle schema regenerated and committed
    - [ ] Index performance verified with EXPLAIN
    - [ ] Hasura metadata reviewed and secured
    - [ ] Changes tested in staging environment

    ## Completed in PR `#603`
    ✅ Centralized \`ScopeType\`, \`WorkspaceActionType\`, \`OperationMeta\` (camelCase)
    ✅ Created \`toActionType\` and \`toScope\` helpers
    ✅ Removed legacy \`select-scope-conversation-window.ts\`
    
    ## Remaining Work
    
    ### 1. Remove Double-Casts (\`as unknown as ...\`) (P1)
    **Locations (from PR `#600` review):**
    - \`apps/pro-web/components/routes/chat/chat-list/message-pair-accordion.tsx\`
    - \`apps/pro-web/components/routes/chat/chat-message-actions.tsx\`
    - Various message handling code
    
    **Tasks:**
    - [ ] Audit all \`as unknown as\` casts
    - [ ] Replace with proper type guards or union types
    - [ ] Update affected interfaces to be type-safe
    
    ### 2. Create Shared Hasura GraphQL Helper (P1)
    **Context:** Multiple files duplicate Hasura client initialization and error handling.
    
    **Files with duplication:**
    - \`apps/pro-web/services/hasura/hasura.service.ts\`
    - \`apps/pro-web/app/actions/chat-memory/*.ts\`
    
    **Tasks:**
    - [ ] Create \`lib/hasura/client.ts\` with:
      - \`getHasuraClient(jwt?: string)\`
      - Standard error transformation
      - Retry logic abstraction
    - [ ] Replace all inline Hasura client creation
    - [ ] Ensure consistent error handling
    
    ### 3. Introduce \`normalizeMessages\` Utility (P1)
    **Context:** Message normalization scattered across hooks and components.
    
    **Tasks:**
    - [ ] Create \`lib/chat/normalize-messages.ts\`
    - [ ] Consolidate:
      - Role casing (lowercase)
      - ID field normalization (AiMessage.id vs Message.messageId)
      - Deduplication logic
      - Sorting by createdAt
    - [ ] Update \`use-mb-chat.tsx\` and \`use-workspace-chat.tsx\` to use utility
    
    ### 4. Remove Remaining \`any\` Types (P1)
    **High-impact locations:**
    - Message role comparisons that cast to \`any\`
    - Event handlers with \`any\` parameters
    - Props marked as \`any\` (now partially fixed in `#603`)
    
    **Acceptance Criteria:**
    - [ ] No \`any\` types in new code
    - [ ] Existing \`any\` types reduced by >80%
    - [ ] All message-related code fully typed
    
    ## Definition of Done
    - [ ] All double-casts removed
    - [ ] Shared Hasura helper created and adopted
    - [ ] Message normalization centralized
    - [ ] Type safety improved across codebase
    - [ ] No new TypeScript errors introduced

    ## Completed in PR `#603`
    ✅ Drizzle-based ingestion (\`ingest-assistant-answer.ts\`)
    ✅ Drizzle-based retrieval (\`retrieve-assistant-answer-memories.ts\`)
    ✅ Scope-aware conversation window (\`get-scope-conversation-window.ts\`)
    ✅ Simplified Hasura service (removed complex retry logic)
    
    ## Critical: RAG Embedding Blocks Not Returning (P0)
    
    **Reported by `@AndlerRL` (2026-02-03):**
    > The simple RAG system consists in only querying the assistant messages related to the conversation and to the user query which is happening but with some bugs after retrieving the embedding blocks—is not returning blocks. We need to clean up this code and relevant changes to the components.
    
    **Investigation Areas:**
    \`\`\`typescript
    // apps/pro-web/app/actions/chat-memory/retrieve-assistant-answer-memories.ts
    // 1. Verify embedding search is returning results
    // 2. Check token budget isn't filtering all results
    // 3. Ensure deduplication isn't removing valid blocks
    // 4. Validate scope filtering (doc_root vs heading_thread)
    
    // apps/pro-web/lib/chat/chat-context-utils.ts - getRagContext
    // 5. Verify finalUserPrompt includes retrieved blocks
    // 6. Check followingQuestionsPrompt fallback isn't bypassing RAG
    // 7. Ensure scopedHistory is properly constructed
    \`\`\`
    
    **Debugging Steps:**
    - [ ] Add debug logging to \`retrieveAssistantAnswerMemories\`:
      - Raw DB query results (count, first 3 items)
      - Post-dedup count
      - Post-token-budget count
      - Final returned count
    - [ ] Add debug logging to \`getRagContext\`:
      - \`isRagEnabled\` value
      - \`shouldUseQChain\` value
      - Retrieved memories count
      - Final prompt length/structure
    - [ ] Test with known data:
      - Create test thread with embedded assistant answers
      - Verify embeddings are stored correctly
      - Query directly via SQL to confirm retrieval works
      - Compare with UI results
    
    **Acceptance Criteria:**
    - [ ] RAG retrieval returns expected blocks for scoped queries
    - [ ] Blocks are correctly inserted into user prompt
    - [ ] Debug logs show clear data flow
    - [ ] Tests added for edge cases (empty results, token limits, scope filtering)
    
    ## Remaining Work from PR `#600`
    
    ### 1. Consolidate \`embedText1536\` with Guards (P1)
    **File:** \`apps/pro-web/lib/helpers/embeddings.ts\` (or similar)
    
    **Tasks:**
    - [ ] Add timeout guard (10s default)
    - [ ] Add retry logic (max 3 attempts)
    - [ ] Centralize error handling
    - [ ] Add Sentry tracking for failures
    - [ ] Remove duplicate embed calls
    
    ### 2. Improve \`saveNewMessage\` Retry Logic (P1)
    **File:** \`apps/pro-web/services/hasura/hasura.service.ts\`
    
    **Current issue:** Generic retry doesn't preserve original error context.
    
    **Tasks:**
    - [ ] Distinguish schema errors (missing columns) from network errors
    - [ ] Only retry on transient failures
    - [ ] Log original error before retry
    - [ ] Add max retry count (currently infinite)
    - [ ] Return structured error (type + message)
    
    ### 3. Strengthen Retrieval Typing (P1)
    **File:** \`apps/pro-web/app/actions/chat-memory/retrieve-assistant-answer-memories.ts\`
    
    **Tasks:**
    - [ ] Remove unsafe casts in query results
    - [ ] Add runtime validation for DB-returned shapes
    - [ ] Escape regex characters in scope_id queries
    - [ ] Add null checks for optional fields
    
    ### 4. Fix \`public.message <-> public.message\` Relationship (P1)
    **Context (from `@AndlerRL`):**
    > The relationship of \`public.message <-> public.message\` shouldn't go.
    
    **Tasks:**
    - [ ] Review migration adding self-referential FK
    - [ ] Verify if relationship is needed for threading
    - [ ] If not needed, create migration to drop it
    - [ ] Update Drizzle schema to reflect change
    
    ## Definition of Done
    - [ ] RAG embedding blocks retrieval bug fixed and tested
    - [ ] Debug logging added and verified in staging
    - [ ] Embedding utility consolidated with guards
    - [ ] Retry logic improved with error context
    - [ ] Retrieval typing hardened
    - [ ] Message relationship reviewed and fixed

    **Current duplication:**
    - \`apps/web/components/routes/chat/prompt-form/prompt-enhancer.tsx\`
    - \`apps/pro-web/components/routes/chat/prompt-form/prompt-enhancer.tsx\`
    
    **Tasks:**
    - [ ] Create \`packages/shared-ui/prompt-enhancer.tsx\` (or similar shared location)
    - [ ] Consolidate both implementations:
      - Merge feature sets
      - Add Templates button functionality (currently non-functional)
      - Implement proper memoization (useMemo for suggestions, useCallback for handlers)
    - [ ] Update both apps to import shared component
    - [ ] Remove duplicated code
    - [ ] Ensure SSR compatibility
    
    **Acceptance Criteria:**
    - [ ] Single source of truth for PromptEnhancer
    - [ ] Templates feature implemented or removed if not needed
    - [ ] No performance regressions
    - [ ] Works in both web and pro-web

    **a) \`apps/pro-web/components/routes/workspace/document-thread-outline.tsx\`**
    \`\`\`typescript
    // WRONG: Early return before hooks
    if (!currentDocument) return null;
    const sections = useMemo(() => ...);
    
    // FIX: Move hooks before early return
    const sections = useMemo(() => ...);
    if (!currentDocument) return null;
    \`\`\`
    
    **b) \`apps/pro-web/lib/hooks/use-workspace-chat.tsx\`**
    \`\`\`typescript
    // WRONG: Hooks called inside async handlers
    const handleEdit = async () => {
      const scopedHistory = await selectScopeConversationWindow(...);
      // ... other async work
    };
    
    // FIX: Destructure at top level, use values in handler
    const { scopedHistory } = useSomeHook();
    const handleEdit = async () => {
      // use scopedHistory
    };
    \`\`\`
    
    **Tasks:**
    - [ ] Audit all components for early returns before hooks
    - [ ] Move hook calls to top of component/hook functions
    - [ ] Refactor async handlers to use pre-fetched hook data
    - [ ] Enable \`react-hooks/rules-of-hooks\` ESLint rule (if disabled)
    
    ### 3. Fix URL Utilities (P1)
    **Context:** User requested consolidation to \`lib/url.ts\`.
    
    **Current issues:**
    - Regex not escaped in domain-slug matching (ReDoS risk)
    - Fallback builders can create malformed paths
    - Scattered across multiple files
    
    **Tasks:**
    - [ ] Create \`apps/pro-web/lib/url.ts\` with:
      - \`parseDomainSlug(url: string)\` (with escaped regex)
      - \`buildChatUrl(params)\`
      - \`buildWorkspaceUrl(params)\`
      - \`buildDocumentUrl(params)\`
    - [ ] Replace all inline URL logic
    - [ ] Add tests for edge cases (malformed URLs, special chars)
    
    ### 4. Add Stable Event Handlers & Timer Cleanup (P1)
    **File:** \`apps/pro-web/components/routes/workspace/workspace-document-text-editor.tsx\`
    
    **Issues:**
    - Debounced timers not cleared on unmount (memory leak)
    - Event handlers recreated on every render (unnecessary re-renders)
    
    **Tasks:**
    - [ ] Wrap event handlers in \`useCallback\`
    - [ ] Add \`useEffect\` cleanup for debounce timers
    - [ ] Verify no stale closures
    - [ ] Add React DevTools profiling to confirm optimization
    
    ### 5. Normalize Message Shapes in Chat Lists (P1)
    **Files:**
    - \`apps/pro-web/components/routes/chat/chat-list/*.tsx\`
    
    **Tasks:**
    - [ ] Standardize on \`AiMessage | Message\` union
    - [ ] Remove casts to \`any\`
    - [ ] Use type guards for role/id checks
    - [ ] Ensure consistent ordering/deduplication
    
    ### 6. DOM Element \`$\` Prefix Convention (P2)
    **Context:** User coding style preference.
    
    **Tasks:**
    - [ ] Prefix all DOM element variables with \`$\`:
      \`\`\`typescript
      const \$input = document.querySelector('input');
      const \$button = useRef<HTMLButtonElement>(null);
      \`\`\`
    - [ ] Update existing code incrementally (low priority)
    - [ ] Add ESLint rule or document convention
    
    ## Definition of Done
    - [ ] PromptEnhancer consolidated and shared
    - [ ] All Rules of Hooks violations fixed
    - [ ] URL utilities centralized in \`lib/url.ts\`
    - [ ] Stable event handlers and timer cleanup implemented
    - [ ] Message shapes normalized
    - [ ] ESLint passes with no warnings

    \`\`\`
    
    **d) Token Budget Tests**
    \`\`\`typescript
    // Test token calculation and truncation logic
    describe('token budgeting', () => {
      it('should fit memories within budget');
      it('should prioritize higher cosine scores');

    - \`apps/pro-web/lib/helpers/rag/operations.ts\`
    - \`apps/pro-web/app/actions/chat-memory/*.ts\`
    - All new utility functions
    
    **Format (TSDoc):**
    \`\`\`typescript
    /**
     * Retrieves assistant answer memories for a given user query and scope.
     *
     * `@param` args - Configuration object

      SHOW_TOKENS: process.env.NEXT_PUBLIC_DEBUG_TOKENS === 'true'
    };
    \`\`\`
    
    **Improved (dynamic):**
    \`\`\`typescript
    export const DEBUG_FLAGS = {
      get RAG_LOGGING() {
        return typeof window !== 'undefined'
          ? window.localStorage.getItem('debug:rag') === 'true'

    - [ ] Ensure SSR compatibility (check \`typeof window\`)
    
    ### 4. Remove Test Files with Wrong Message Structure (P2)
    **Context:** Some test files use outdated Message shape.
    
    **Tasks:**
    - [ ] Audit all \`*.test.ts\` and \`*.spec.ts\` files
    - [ ] Update to use current AiMessage | Message union

    All issues are assigned to you and link back to:

    📝 Note: Duplicate Issues

    I also see older duplicates (#604, #605) from a previous attempt. You may want to close those to avoid confusion.

    🏷️ Missing Labels

    The following labels don't exist in your repository (issues were created anyway, but labels couldn't be applied):

    • refactor
    • typescript
    • testing

    The bug and documentation labels worked fine. If you'd like, you can:

    1. Create the missing labels via Settings → Labels → New Label
    2. Manually add them to the issues
    3. Or just use the existing labels you have

    🎯 Next Steps

    1. Close duplicates: #604, #605 (if desired)
    2. Start with Phase 2 (#610) - Critical RAG bug affecting users
    3. Follow up with Phase 0 (#606) - Performance improvements via operator classes
    4. Add missing labels (optional)

    You can view all your phase issues with: is:issue assignee:@me label:bug,documentation

    Let me know if you need any adjustments to the issues!

    Learning: For bitcashorg/masterbots, RAG changes must align with the current architecture (no “legacy” labeling of existing code paths). New RAG components should integrate with existing modules and data shapes rather than introducing parallel logic.

    Learning: In bitcashorg/masterbots RAG system, the `public.message <-> public.message` self-referential relationship should be preserved. The RAG system queries assistant messages related to the conversation and user query. There is a known bug where embedding blocks are not being returned after retrieval—the embedding fetch succeeds but blocks are not propagated to the final prompt.

    Learning: In `apps/masterbots.ai/lib/helpers/ai-helpers.ts` the `verifyDuplicateMessage` function should:
    • Use `message.content` as the sole de-duplication key so provisional (no-slug) and persisted (slugged) messages merge properly.
    • Return the full `message` object (not just a string key) for the continuation prompts (`CONTINUE_GENERATION_PROMPT`, `CONTINUE_GENERATION_PROMPT_2`) because their content repeats and they must remain distinct.
    • No explicit `!message.content` guard is needed; `return message.content` already yields `undefined` when content is missing.
