 ## 3 Remaining Compliance Failures
 
-| # | Test | Error | Root Cause |
-|---|---|---|---|
-| 1 | `not_eq` | `undeclared 'eq_SLASH_tests'` | Cross-namespace: `eq/tests` fn from `clojure.core-test.eq` not loaded |
-| 2 | `add_watch` | `undeclared 'testvar_a'` | `(def testvar-a 0)` inside deftest body — Nim requires var decl before use in closures |
-| 3 | `remove_watch` | `undeclared 'watchable'` | Same — `(def watchable 0)` inside deftest body, referenced in closures |
+### 1. `not_eq` — Cross-namespace dependency
+- **Error**: `undeclared identifier: 'eq_SLASH_tests'`
+- **Cause**: Test calls `(eq/tests (complement not=))` where `eq/tests` is a function defined in `clojure.core-test.eq` namespace (separate file). Our compiler processes each test file independently — it doesn't load required namespaces.
+- **Fix needed**: Multi-file compilation — `ns :require` should inline/compile required files and make their functions available.
 
-All 3 require deeper architectural changes:
-- Multi-file compilation or inline required namespaces
-- Top-level def hoisting across closure boundaries
+### 2. `add_watch` — Closure scoping with fn params
+- **Error**: `undeclared identifier: 'ref1'`
+- **Cause**: The test defines functions like `(fn [key ref old new] ...)` where `ref` gets mangled to `ref1`. These fn params are used inside deeply nested closures (try/catch inside fn inside testing block). The IIFE wrapping by `emitBlock` creates scope boundaries that prevent fn params from being visible in inner closures.
+- **Fix needed**: IIFE-wrapped closures must capture enclosing scope variables. Either stop wrapping non-last forms in IIFEs, or use Nim closures that properly capture outer variables.
+
+### 3. `remove_watch` — Same closure scoping issue
+- **Error**: `undeclared identifier: 'ref1'`
+- **Cause**: Same as `add_watch` — fn params not visible across IIFE boundaries.
+- **Fix needed**: Same as `add_watch`.
+
+## Roadmap to 100%
+
+### Phase A: Closure Scoping Fix (fixes add_watch + remove_watch)
+- **Approach**: Instead of wrapping non-last forms in `discard ((proc(): CljVal = ...)())`, emit them as direct statements. The IIFE wrapping was added to handle multi-line expressions as non-last forms, but it breaks variable scoping.
+- **Alternative**: Use Nim's `{.inline.}` procs or `block:` labels instead of IIFEs for scope isolation.
+- **Impact**: +2 tests (232/233)
+
+### Phase B: Multi-file Compilation (fixes not_eq)
+- **Approach**: When `ns :require` encounters a namespace, find and compile the corresponding `.cljc`/`.clj` file, inline its top-level defs into the current compilation unit.
+- **Key files**: `src/cljnim.nim` (file resolution), `src/emitter.nim` (ns handler)
+- **Impact**: +1 test (233/233)
+
+### Phase C: Symbol Emit Fix (fixes 2 unit tests)
+- **Approach**: When emitting a bare symbol that's not a local var and not a runtime function, check if it was defined as a `def`/`defn` in the current compilation unit. If so, emit the mangled name directly instead of `cljSymbol(...)`.
+- **Impact**: +2 unit tests (80/80)
+
+## Session Log
+
+### 2026-05-11 (late session) — Bulk fixes
+- Reader: prefer `:default` over `:clj` in conditionals
+- Emitter: `cond`, `definterface`, `new` special forms
+- Emitter: `ns` alias registration, `when` discard, `try/catch` scope + type mapping
+- Emitter: `emitBlock` var hoisting out of IIFEs
+- Emitter: removed all DEBUG stderr output
+- Runtime: `random-uuid`, `System/getProperty`, `vreset!`, `restart-agent`, `require`/`eval`/`resolve` stubs
+- Runtime: `Boolean`/`Object`/`Integer` constructors
+- Runtime: seq overloads for `cljAssoc`, `cljDissoc`, `cljGet`, `cljExInfo`, `cljTransduce`
+- Result: 220/233 → 230/233 compliance, 77/80 → 78/80 unit tests
