Section 2 — entry points

Two ways the user reaches AE

/network?active-view=anything-engine

The canonical product surface. Top-nav sparkle icon → URL switches → network-canvas.tsx renders <AnythingEngineCanvasOpenUI/> from openui/anything-engine-canvas-openui.tsx. This is what Mark dogfoods.

CANONICAL

/chat (standalone route)

Auth-gated full-page route. src/routes/_authed/chat.tsx renders <ChatShell/> from components/chat-shell.tsx. The full sandbox-port shape with side-bar, history list, persistent layout. Mark gated from this until history-replay backports stabilize.

DEEP-LINK

Section 2b — new this push (L73)

Crash-safety: 4 ErrorBoundaries in production

Pre-L73, the only React ErrorBoundary in the app was around the AE <Renderer/> (shipped May 9). A render throw anywhere else would blank-canvas the whole app. The L73 push (commit 1babb15c) added 3 new boundaries — the count is now 4.

AuthedContent boundary (whole-app shell)

Wraps the entire authed surface. A render throw in any feature canvas (network / copilot / settings / anything) shows a recoverable error UI instead of a blank page. Biggest single crash-blast-radius reduction.

SHIPPED L73

Network route boundary (per-canvas)

Wraps the network top-nav active-view canvas slot. A throw in OutcomesCanvas / DiscoverCanvas / TeamsCanvas / etc. no longer takes down the surrounding chrome. User can still tab to a working canvas.

SHIPPED L73

CrayonChat boundary (copilot dialog)

Wraps the CrayonChat composer + thread inside the copilot dialog. A render throw in a custom template (one of 18) no longer kills the dialog — user can dismiss and reopen.

SHIPPED L73

AE Renderer boundary (May 9 origin)

First boundary in the app. Wraps the OpenUI 0.5 <Renderer/> in anything-engine-canvas-openui.tsx. Catches render throws from primitive registry mounts so a malformed openui_lang from the server doesn’t blank the canvas. Commit 3d290fc.

PRE-EXISTING

Net effect. 1 boundary → 4 boundaries in a single PR. Plus noImplicitOverride strict flag now enforced in tsconfig.json — one more class of refactor regression caught at typecheck time. See perf-wins.html wave 21-23 section for the full L73 commit breakdown.

Section 3 — the 9 BFFs

server/ — TanStack Start server functions

Every Xano endpoint the AE talks to has a thin TypeScript wrapper. The wrappers handle multipart encoding, env var resolution, response typing, and (post-this-session) authenticated user_id passthrough.

classify-fn.ts — ep 8400 (Haiku 4.5)

Front-door classifier. Routes a user query to one of 15 outcome classes (find_investors, find_talent, etc.) or "ask_back" if confidence < 0.7. Stateless, no Zep memory. Source-of-truth prompt: prompts/anything_engine/classify.md.

STATELESS

dispatch-fn.ts — ep 8399 (legacy)

Legacy dispatch from the pre-OpenUI-0.5 era. Used by chat-shell.tsx. Returns DispatchEvent[]. Now passes authenticated user_id (was hardcoded "15"). Wraps Xano group 1270.

USER_ID WIRED

openui05-dispatch-fn.ts — ep 8506 (OpenUI 0.5)

Canonical dispatch for the OpenUI 0.5 canvas. Returns top-level openui_lang string ready to feed into <Renderer/>. Wraps Xano group 1276. Server-side handles same-firm dedup + banned-phrase lint + SIGNAL TAXONOMY tag enforcement. Switches Opus 4.1 for find_investors, Haiku 4.5 for everything else.

USER_ID WIRED

interview-fn.ts — ep 8411 (Haiku 4.5)

Per-class interview gate for find_investors / find_customers / research_person. Returns {ready, summary, next_question, missing_fields, options[]}. find_talent has its own endpoint. Now passes user_id for Zep memory continuity per turn.

USER_ID WIRED

find-talent-interview-fn.ts — ep 8484 (Haiku 4.5)

find_talent dedicated interview endpoint. MCQ-driven 8-dim adaptive interview per Mark's May 6 verbatim prompt. Returns {stage, payload, raw, class}.

USER_ID WIRED

start-outcome-fn.ts — ep 8417

Eager suggestion_request row creation. Mark's Apr 30 directive: file uploads need a suggestion_request_id BEFORE any file is attached. Frontend calls on chat-mount or first tile-click.

USER_ID WIRED

upload-files-fn.ts — ep 8420 (multipart)

Multipart file upload. Reconstructs FormData from base64-encoded blobs. Triggers fn 12917 (extract-pitch-profile) + fn 12918 (build-pitch-profile) + embed step. Was the SECOND hardcoded "15" leak bug. Now wired correctly.

USER_ID WIRED (P0 BUG)

pitch-profile-fn.ts — ep 8420 GET

Read-only ready-gate poll over fundraising_pitch_profiles (table 710). Returns {ready, narrative_count, missing_fields, profile}. Frontend polls every ~5s after deck upload until ready=true. Stateless — no user_id needed (keyed on suggestion_request_id which is already user-scoped).

N/A (READ-ONLY)

build-summary-fn.ts — ep 8505

Re-runs the summary synthesizer when the user edits a confirmation field. Stateless — synthesis only, no DB write. Used by the post-confirmation readback edit-loop.

N/A (SYNTH ONLY)

Section 4 — 10 hooks

hooks/ — React state primitives

use-conversation-starters.tsx

487 LOC. Builds 4 dynamic starter slots (calendar / active-work / network-intel / time-of-day) from live data. Mark tell #4: starters are NEVER static strings. Capped at 3 per session for clean 3-col grid alignment.

DYNAMIC

use-dispatch-gate.ts (+ test)

Predicate hook for whether dispatch button can fire. Combines ready-gate poll state, narrative count, polling state, and error. 4 test cases.

GATE

use-pitch-profile-poll.ts (+ test)

Wraps pitchProfileFn in TanStack Query with ~5s refetch interval. Returns {profile, ready, narrativeCount, missingFields, isPolling, error}. 4 test cases.

POLL

use-preload-context.ts

Pre-loads user + company baseline context on Outcomes tab open. Lifts data into the canvas before the user types anything. Speeds first-turn perceived latency.

PRELOAD

use-selected-anything-engine-conversation.ts

URL-param-backed selection state for the conversation history list. Handles JSON-parse quirk where TanStack Router serializes numbers as quoted strings.

URL STATE

use-anything-engine-conversation-search.ts

URL-param-backed search query state for filtering the left-rail conversation list.

URL STATE

use-voice.ts (TTS)

Two-provider TTS: Gradium (primary) + ElevenLabs (fallback). 8 curated voices (4M/4F). Streaming + blob playback. Env: VITE_GRADIUM_API_KEY, VITE_ELEVENLABS_API_KEY.

VOICE

use-voice-input.ts (STT)

Web Speech API primary, MediaRecorder + Gradium ASR fallback. Press-to-talk UX (not silence detection).

VOICE

Section 5 — AE lib + openui

Pure functions + OpenUI primitives

The AE lib/ directory grew from 4 modules pre-L20 to 23 modules post-L65 as helpers were extracted out of chat-shell.tsx, components.tsx, and anything-engine-right-rail.tsx. Almost all carry colocated .test.ts coverage. Highlights below; the full inventory is in the tree above.

lib/anything-engine-hotkeys.tsx

React provider + context for AE keyboard shortcuts. Wraps the canvas + chat-shell.

CTX

lib/build-thread-lang.ts (+ test)

Builds a top-level OpenUI Lang string from the per-turn event log. Used by the canvas to feed <Renderer/>. 15 unit tests including malformed-lang edge case (closed L65).

EXTRACTED

lib/coerce-conversation-title.ts (+ 13 tests)

Defensive helper that detects MCQ-fragment titles (money ranges, percentages, single-clause text) and prefixes "New outcome · " so the left rail history stays scannable.

EXTRACTED

lib/leak-filter.ts + sanitize-ask-back-reasoning.ts (+ tests)

Guardrails. Banned-phrase + internal-routing-reasoning suppression so server-side reasoning never reaches the canvas surface. Mark spec May 7 fix.

EXTRACTED

lib/contact-card-utils.ts + adapt-contact-card.ts + firm-name-utils.ts (+ tests)

Result-card helpers. Dedupe firm-name labels, build dispatch-card props, adapt legacy Crayon contact_card payload to OpenUI ContactCard shape. 31 + 23 + tests for firm-name-utils.

EXTRACTED

lib/dispatch-card-helpers.ts + class-labels.ts + scanning-phrases.ts (+ tests)

Per-class labels + scanning-state phrases (varied verbs by outcome class) + dispatch-card formatters. 36 + 33 + 12 tests respectively.

EXTRACTED

lib/format-helpers.ts + relative-time.ts + tooltip-position.ts (+ tests)

Pure formatters: USD ($1.2M / $850K), bytes (12 KB / 5 MB), relative time (2h / 3d), tooltip-arrow positioning math. Right-rail + chat-shell + composer all consume.

EXTRACTED

lib/strength-meter-utils.ts + source-label.ts + starter-helpers.ts (+ tests)

Match-strength bond color/label, signal-source taxonomy label, conversation-starter slot builders. 43 + 38 + 26 tests.

EXTRACTED

lib/mock-outcomes.ts

Mock data fallback when the outcomes API is unavailable. Used by chat-shell, right-rail, outcome-sidebar, anything-engine-right-rail. Marked TODO: replace with real outcomes API once backend lands.

MOCK

openui/anything-engine-canvas-openui.tsx

~2,080 lines. The OpenUI 0.5 network-tab canvas. Renders welcome state (hero + 3 starters + 15 tile expansion), interview turns, dispatch confirmation, and result cards. Uses @openuidev/react-lang Renderer with the components.tsx primitive registry.

CANVAS

openui/components.tsx

~2,080 lines. OpenUI primitive registry. Defines every component the Renderer can mount: ContactCard, ScanningCard, InterviewTurn, DispatchConfirmation, ButtonGroup, ErrorState, etc. Schema-validated via Zod.

PRIMITIVES

openui/crayon-to-openlang.ts (+ 9 tests)

Adapter layer for legacy DispatchResult.events[] (Crayon shape) → OpenUI Lang string. Used by chat-shell to feed legacy event streams into the new Renderer.

ADAPTER

Section 5b — new this wave

Shared lib + per-feature utils after L65

L20-L73 extracted ~75 helper modules across the codebase, with byte-identical copies promoted to src/lib/ and feature-internal helpers landing in per-feature utils/ + lib/. Each extraction carries colocated unit tests. Total: 1241 tests across 72 files.

Why it matters. Pre-sweep, identical helpers were copy-pasted across 2-7 sites with subtle drift. Post-L65, every cross-feature primitive lives in exactly one canonical location with full test coverage. The next person to touch chat-shell, copilot, or the right-rail can grep for the helper they need rather than rewriting it.

src/lib/ — cross-feature shared (10 modules, all with colocated tests except utils.ts & audio.ts)

src/lib/utils.ts

Canonical cn() Tailwind class merger (clsx + twMerge). Used everywhere — single source of truth for class composition.

FOUNDATION

src/lib/audio.ts

Premium chime — warm filtered ADSR-enveloped tones for start/stop. Replaces inline AudioContext code in mic-button + voice-bar.

FOUNDATION

src/lib/djb2.ts (+ test)

DJB2 string hash. Was duplicated inline in 2 locations. Promoted to canonical.

DEDUPED

src/lib/name-initials.ts (+ test)

Canonical nameInitials, emailNameInitials, firstTwoInitials. Avatar-fallback logic was copy-pasted across 4+ surfaces; now one helper.

DEDUPED

src/lib/person-subtitle.ts (+ test)

Builds the "Title @ Company" or "Email" subtitle line under a person row. Unified 5 inline copies across copilot, network, search, person-sheet, person-picker.

DEDUPED

src/lib/sse-stream.ts (+ test)

Server-Sent Events parser. Was leverage-loops-owned; promoted to src/lib. Used by leverage-loops, meeting-prep, outcomes for streaming Xano responses. Replaces 47+ inline lines per call site.

PROMOTED

src/lib/sanitize-html.ts (+ test)

DOMPurify wrapper with server-fallback + XSS guard for xlink:href + formaction. 55 unit tests covering edge cases.

FOUNDATION

src/lib/tts-text-prep.ts (+ test)

Strips markdown + de-acronyms + sentence-splits text before sending to TTS. 43 tests. Was duplicated between AE voice + copilot voice; now one canonical implementation.

DEDUPED

src/lib/date-formatters.ts (+ test)

4 named exports (formatDate, formatDateShort, formatDateTime, formatDay) consolidating 6 inline copies across calendar, history, meeting-prep, conversation-list, etc.

DEDUPED

src/lib/date-range-formatters.ts (+ test)

formatDateRangeSimple + formatDateRangeSmart. Unified 2 of 3 sites; 17 tests. (3rd site is feature-specific, intentionally separate.)

DEDUPED

src/lib/timezone.ts (+ test)

toTZDate timezone helper for calendar / meeting-prep. 10 tests covering DST + offset edges.

FOUNDATION

Per-feature utils + lib (19 directories, 14 carry tests)

Cross-feature dedupes — 14 promotions documented

Each row below names a primitive that existed as N inline copies before this wave and is now in exactly one canonical location.

1. djb2 hash → src/lib/djb2.ts

2 inline copies replaced. Used by deterministic-color avatars and stable hash IDs.

2 → 1

2. nameInitials / emailNameInitials → src/lib/name-initials.ts

2 inline copies replaced for firstTwoInitials + new canonical for both name- and email-derived initials.

2 → 1

3. getAuthToken → src/integrations/xano (canonical)

7 inline copies across BFFs and direct fetchers consolidated. Auth-token leaks were a recurring P0 source — now one helper to inspect.

7 → 1

4. personSubtitle → src/lib/person-subtitle.ts

5 inline copies unified. "Title @ Company" or "Email" line under a person row.

5 → 1

5. sse-stream → src/lib/sse-stream.ts (was leverage-loops-owned)

Promoted out of feature-local. Now consumed by leverage-loops, meeting-prep, outcomes. Replaces 47 inline lines per call site (3 sites).

3 → 1

6. formatDate → src/lib/date-formatters.ts

6 inline copies replaced by 4 named exports.

6 → 1

7. formatDateRangeSimple + formatDateRangeSmart → src/lib/date-range-formatters.ts

2 of 3 sites unified. 3rd site is intentionally feature-specific.

3 → 1

8. TTS text-prep → src/lib/tts-text-prep.ts

Duplicated between AE voice + copilot voice; now one canonical implementation. 43 tests.

2 → 1

9. formatUsdShort + formatBytes → AE lib/format-helpers.ts (canonical)

AE right-rail was carrying its own copy; now imports from lib/. Other surfaces (chat-shell, dispatch-card) already use canonical.

2 → 1

10. buildAttendees → meeting-prep/utils/attendees.ts

3 inline copies (2 in meeting-prep canvases + 1 in copilot) unified. Builds the comma-separated attendee list for prep cards.

3 → 1

11. buildNetworkSummary → copilot/utils/network-summary.ts

Was duplicated across 2 canvas surfaces; now one helper.

2 → 1

12. filterIconsBySearch → collections/utils/filter-icons-by-search.ts

Originally a useMemo inside teams; now reused by collections + teams. First cross-feature reuse out of a feature-owned helper.

2 → 1

13. formatCategoryName + stripBrackets → email-inbox/utils

Final byte-identical cross-file duplicate in email-inbox. 2 inline copies unified.

2 → 1

14. 5 byte-identical gridNodes adapters → discover/utils/grid-node-adapters.ts

Largest single dedupe of the wave. 5 byte-identical adapter functions across discover surfaces consolidated into one module. Closed L65.

5 → 1

What this gets you. 1241 unit tests across 72 test files (was 0 pre-L20). Every helper that ships in PR #343 has executable proof of behavior. The architecture-map of pure-function helpers is now searchable: grep src/lib first, then per-feature utils/ or lib/, then the component itself.

End-to-end find_investors flow

1. User clicks find_investors tile
   → anything-engine-canvas-openui.tsx
   → composer pre-fills with starter prompt

2. User types and hits Send
   → runTurn() in canvas-openui.tsx

   → setLatestClass("find_investors")

3. Interview phase begins

   → User clicks chip → MCQ value submits → next interviewFn call
   → Loop until ready=true

4. Result count picker (Mark spec May 8)
   → Result count picker turn renders
   → User picks 20 / 100 / "as many as you can"

5. Format picker (Mark spec May 8)
   → Format picker turn renders
   → User picks suggestion / collection / csv / pdf
   → coerceConversationTitle helper sets sane left-rail title

6. Dispatch fires

   → Xano: prefilter → headroom → graph_rag → final-trim
   → Returns openui_lang string with N ContactCard mounts

7. Cards render
