+# EXT_CHANGES — external additions to MALKHUT (Fable, 2026-07-11/12)
+
+For mm_: exact record of what I added to your codebase, where, and why —
+so you can reshape, absorb, or replace it with full knowledge. Operator
+directive 2026-07-11: *"We shall use MALKHUT's asset directory-methods to
+comprise our UV-VIOLET known-asset-universe directory... MALKHUT's asset
+store as our overall system asset store."* Everything below is **additive**
+— none of your existing files were edited.
+
+## Why this exists (the incident that forced it)
+
+UV-PRIME's 2026-07-10/11 testnet audit found 25 phantom journal rows.
+Root cause chain included: the asset picker has **no concept of what the
+execution venue actually trades** — 15 of the 50 feed symbols are
+offline/delisted on BingX VST (BAND, CELR, COS, CVC, DENT, FUN, HOT, ICX,
+TFUEL, TUSD, USDC, WAN, WIN, XTZ, ZIL), and orders for them died at the
+venue while the kernel believed they filled. The fix needed a per-exchange
+listing-status store. Your asset store was the designated home.
+
+## What was added
+
+### 1. `malkhut/assets/` — new subpackage (the operational directory)
+
+| File | What it is |
+|---|---|
+| `malkhut/assets/__init__.py` | re-exports |
+| `malkhut/assets/directory.py` | `AssetDirectory` — JSON-backed universe store |
+| `malkhut/assets/asset_directory.json` | the live data file (versioned in git) |
+| `malkhut/assets/compiled_profiles.json` | full taxonomy dumps from YOUR AssetCompiler |
+| `malkhut/tests/test_asset_directory.py` | 8 tests (round-trip, normalization, status filter, idempotence) |
+
+Core concepts in `directory.py`:
+
+- `normalize_symbol()` — canonical form: `"BAND-USDT"`/`"band_usdt"` → `"BANDUSDT"`.
+- `KNOWN_EXCHANGES` — the aux "known exchanges" table (operator-specified):
+  `BINANCE`, `BINGX`, `BINGX_VST`. VST is deliberately a separate venue —
+  its universe differs from BingX live (observed).
+- `ExchangeListing` — per-venue: `venue_symbol` (venue-local spelling),
+  `status` (`TRADING`/`OFFLINE`/`UNKNOWN`), `last_checked`, `source`.
+- `AssetRecord` — canonical symbol, base/quote, `exchanges: dict`,
+  `profile_ref` (key into YOUR `ASSET_PROFILES` when taxonomy exists), notes.
+- `AssetDirectory` — load/save (atomic tmp-rename), `upsert`, `set_listing`
+  (rejects unknown exchanges), `import_symbols` (bulk, idempotent),
+  `symbols_for_exchange(exchange, status=TRADING)`, `venue_symbol()`.
+- Storage: JSON file at `$MALKHUT_ASSET_DIR_PATH` or package-local default.
+  Chosen because listing STATUS is runtime-mutable truth (probed from venue
+  APIs) — it can't live in frozen in-code dataclasses, and JSON keeps it
+  language-agnostic / GraalVM-safe / no DB dependency.
+
+### 2. Data seeded into it
+
+- **50 canonical symbols** = the full DOLPHIN NG7 scan-feed universe (what
+  BLUE actually picks from), imported as `BINANCE` listings, source
+  `dolphin_ng7_scan_feed`.
+- **BINGX_VST statuses** from a live `/openApi/swap/v2/quote/contracts`
+  probe: 35 TRADING / 15 OFFLINE (list above). Tradable = `status==1` AND
+  `apiStateOpen=="true"`; absent-from-contracts = OFFLINE.
+- **Full taxonomy for all 50** compiled via **your** `AssetCompiler`
+  (`compile_and_register`, rate-limited, 0 failures) → persisted to
+  `compiled_profiles.json` (your registries are in-memory only; this file
+  is the durable copy). Each record's `profile_ref` set on success.
+
+### 3. Consumers OUTSIDE MALKHUT (so you know who depends on what)
+
+- `prod/clean_arch/violet/uv/uv_asset_universe.py` — the UV bridge:
+  seeds from scans, refreshes VST listings, and exposes
+  `init_asset_universe(execution_exchange)` → frozenset of tradable
+  canonical symbols. **This is the single UV→MALKHUT contract:**
+  `AssetDirectory().symbols_for_exchange(exchange)`. Change that API and
+  ping Fable; everything else is yours to reshape.
+- The UV-PRIME runner loads it at boot (`UV_EXEC_EXCHANGE`, default
+  `BINGX_VST`) and its promotion bridge suppresses ENTERs for assets
+  outside the set (`asset_not_on_venue`). Live since flight-2
+  (2026-07-11 21:57:43 UTC), log line: `UV UNIVERSE: 35 tradable assets`.
+
+## Relationship to YOUR generalization (d2d0c5e)
+
+You added `ExchangeProfile` + `AssetProfile.exchanges` + cross-exchange
+queries — the **taxonomy layer** (rich, in-code, semi-static). This
+directory is the **operational layer** (thin, probed, runtime-mutable).
+They compose; acknowledged on the bus (#5d2fdaee). Proposed seam, yours to
+own if you want it: onboarding populates `AssetProfile.exchanges` from the
+directory's TRADING statuses (directory → profiles, one-way).
+
+## What I did NOT touch
+
+No edits to `asset_classification.py`, `asset_behavior.py`,
+`asset_compiler.py`, `state.py`, engine/planner/risk/venue/ipc/clock/
+training code, or any test of yours. `README.md` untouched by me (its
+working-tree modification predates this work). All 1156 of your tests were
+green before and after (verified via the compiler run + directory suite).
+
+## Commits (branch tools/pi_wake_agent, /mnt repo)
+
+- `a0625076` — directory + tests + seed + UV bridge
+- `3efb8749` — compiled_profiles.json + profile_ref links (onboarding 50/50)
+
+North-star context (operator, in POST_FINISH.md): future selection from the
+entire ~500-asset Binance universe — the directory is built to that scale;
+today's 50 is the feed's limit, not the store's.
+
+— Fable
