98fd315f14 Step 10c: unified reactive model — peek + provide! special forms + tracking primitives
CEK evaluator integration:
- peek — non-tracking read from provide frame (like context but never subscribes)
- provide! — mutate value in provide frame (cf_extra made mutable)
- Both dispatch as special forms alongside provide/context

Scope-stack primitives (for adapter/island use):
- provide-reactive! / provide-pop-reactive! / provide-set! — signal-backed scope
- peek (primitive) — non-tracking scope read
- context (override) — tracking-aware scope read
- bind — tracked computation with auto-resubscription
- tracking-start! / tracking-stop! / tracking-active? — tracking context

12/13 user-authored peek/provide! tests pass.
bind integration with CEK context pending (scope vs kont gap).

b3e9ebee1d Step 10c: Vector type + unified reactive model test spec (34 tests)
- Vector of value array added to sx_types.ml (prior commit)
- Vector primitives in sx_primitives.ml (make-vector, vector-ref,
  vector-set!, vector-length, vector->list, list->vector)
- R7RS vector tests
- test-unified-reactive.sx: 34 tests specifying the unified reactive
  model (provide/context/peek/bind replacing signal/deref split).
  All 34 currently fail — implementation next.
- WASM binary rebuilt

5df21fca36 Step 10b: capability-based sandboxing
Capability primitives promoted from mcp_tree.ml to sx_primitives.ml:
- with-capabilities — push cap set, eval body, restore on exit/error
- current-capabilities — returns active capability list (nil = unrestricted)
- has-capability? — check if capability granted (true when unrestricted)
- require-capability! — raise if capability missing
- capability-restricted? — check if any restrictions active

Infrastructure: _cek_call_ref in sx_types.ml (forward ref pattern)
allows primitives to invoke the CEK evaluator without dependency cycles.

10 new tests: unrestricted defaults, scoping, nesting, restore-on-exit.
2693 total tests, 0 regressions.

6fe3476e18 Step 9: mutable data structures — R7RS vectors
New Vector type (value array) with 11 primitives:
- make-vector, vector — constructors
- vector-ref, vector-set! — element access/mutation
- vector-length, vector?, vector-fill! — inspection
- vector->list, list->vector — conversion
- vector-copy — independent copy
- Element-wise equality in safe_eq

10 new tests (2668/2668 pass). Follows Record pattern (value array).

b0a4be0f22 Step 8: numeric tower — exact/inexact predicates + truncate/remainder/modulo
7 new R7RS primitives on the float-based tower (Number of float unchanged):
- exact? / inexact? — integer detection via Float.is_integer
- exact->inexact / inexact->exact — identity / round-to-integer
- truncate — toward zero (floor for positive, ceil for negative)
- remainder — sign follows dividend (= Float.rem)
- modulo — sign follows divisor

8 new tests (2658/2658 pass). No type system, VM, compiler, or parser changes.

4baed1853c OCaml runtime: R7RS parameters, VM closure introspection, import suspension
- R7RS parameter primitives (make-parameter, parameter?, parameterize support)
- VM closure get_val introspection (vm-code, vm-upvalues, vm-name, vm-globals)
- Lazy list caching on vm_code for transpiled VM performance
- VM import suspension: check_io_suspension + resume_module for browser lazy loading
- 23 new R7RS tests (parameter-basic, parameterize-basic, syntax-rules-basic)
- Playwright bytecode-loading spec + WASM rebuild

d4244b47bf R7RS compat library + 45-test suite (27 passing, 17 need lib load fix)
lib/r7rs.sx: guard/with-exception-handler macros, error objects
(make-error-object, error-object?, error-message, error-object-irritants),
R7RS aliases (car/cdr/cadr/null?/pair?/procedure?/boolean=?/symbol->string/
number->string/string->number), string->symbol.

spec/tests/test-r7rs.sx: 9 suites covering call/cc (7), raise (4),
guard (5), with-exception-handler (1), error-objects (4), multi-map (6),
cond=> (4), do-iteration (4), r7rs-aliases (10). 27/44 pass — the 17
failures need r7rs.sx auto-load in the test runner (currently commented
out pending transpiled evaluator hang investigation).
