Ring 2 (bootstrapper): JavaScript translation via js.sx,
Z3/SMT-LIB translation via reader_z3.py. Each define card
now shows SX, Python, JavaScript, and Z3 collapsible panels.
Ring 3 (bridge): Cross-reference index maps function names
to spec files. Each define shows which other spec functions
it references.
Ring 4 (runtime): Test file parsing extracts defsuite/deftest
structure. Fuzzy name matching links tests to functions.
Stats bar shows test count.

1. Extra closing paren in ex-tabs handler
2. tab-content dict values contained (div ...) HTML tags which crash
during register_components since HTML primitives aren't in env

Two issues: `)` inside string content wasn't a syntactic paren,
and one extra syntactic `)` at end of handler. Removed both.

The <slug> route param doesn't match slashes, so
/language/specs/explore/<slug> needs its own defpage
instead of being handled inside specs-page.

The helper was trying to look up all-spec-items from get_component_env(),
but that only contains defcomp/defmacro — not regular defines. Now the
SX routing layer calls find-spec and passes filename/title/desc directly.
Also adds boundary declaration for spec-explorer-data.

- _spec_explorer_data() helper: parses spec files into sections, defines,
effects, params, source blocks, and Python translations via PyEmitter
- specs-explorer.sx: 10 defcomp components for explorer UI — cards with
effect badges, typed param lists, collapsible SX/Python translation panels
- Route at /language/specs/explore/<slug> via docs.sx
- "Explore" link on existing spec detail pages

Add 14 new IO primitives to boundary.sx: web interop (request-form,
request-json, request-header, request-content-type, request-args-all,
request-form-all, request-headers-all, request-file-name), response
manipulation (set-response-header, set-response-status), ephemeral
state (state-get, state-set!), and timing (now, sleep).
All 19 reference handlers now have :returns type annotations using
types.sx vocabulary. Response meta (headers/status) flows through
context vars, applied by register_route_handlers after execution.
Only SSE endpoint remains in Python (async generator paradigm).

New plan page at /etc/plans/spec-explorer describing the "fifth ring"
architecture: SX exploring itself through per-function cards showing
source, Python/JS/Z3 translations, platform deps, tests, proofs, and
usage examples.

Specs nav reorganized from flat list into 6 sections with children:
Core (5), Adapters (4), Browser (4), Reactive (1), Host Interface (3),
Extensions (4). Added missing spec items: adapter-async, signals,
boundary, forms, page-helpers, types. Architecture page updated to
match. New essay on ars, techne, and the self-making artifact chain.

All 11 define-io-primitive entries now declare :effects [io].
Signal primitives annotated: signal/deref/computed = [] (pure),
reset!/swap!/effect/batch = [mutation].

Phase 6 — deftype: named type aliases, unions, records, and parameterized
types. Type definitions stored as plain dicts in *type-registry*. Includes
resolve-type for named type resolution, substitute-type-vars for
parameterized instantiation, subtype-resolved? for structural record
subtyping, and infer-type extension for record field type inference via get.
Phase 7 — defeffect: static effect annotations. Effects stored in
*effect-registry* and *effect-annotations*. Supports :effects keyword on
defcomp and define. Gradual: unannotated = all effects, empty list = pure.
check-body-walk validates effect containment at call sites.
Standard types defined: (maybe a), type-def, diagnostic, prim-param-sig.
Standard effects declared: io, mutation, render.
84/84 type system tests pass. Both Python and JS bootstrappers succeed.

New platform_js primitives for direct DOM property/method access and
cross-origin iframe communication. Service worker static cache bumped
to v2 to flush stale assets. Removed experimental video embed from
header island, routes, and home page.

Extend the type annotation system from defcomp-only to fn/lambda params:
- Infrastructure: sf-lambda, py/js-collect-params-loop, and bootstrap_py.py
now recognize (name :as type) in param lists, extracting just the name
- bootstrap_py.py: add _extract_param_name() helper, fix _emit_for_each_stmt
- 521 type annotations across 22 .sx spec files (eval, types, adapters,
transpilers, engine, orchestration, deps, signals, router, prove, etc.)
- Zero behavioral change: annotations are metadata for static analysis only
- All bootstrappers (Python, JS, G1) pass, 81/81 spec tests pass

- ~video-player defisland persists across SPA navigations (morph-safe)
- Clicking "reactive" cycles colour (signal) + fetches random YouTube video (sx-get)
- sx-trigger="fetch-video" + dom-first-child check: video keeps playing on repeat clicks
- Close button (x) clears video via /api/clear-video hypermedia endpoint
- Autoplay+mute removes YouTube's red play button overlay
- Header restructured: logo in anchor, tagline outside (no accidental navigation)
- Flex centering on video container

New hierarchy: Geography (Reactive Islands, Hypermedia Lakes, Marshes,
Isomorphism), Language (Docs, Specs, Bootstrappers, Testing),
Applications (CSSX, Protocols), Etc (Essays, Philosophy, Plans).
All routes updated to match: /reactive/* → /geography/reactive/*,
/docs/* → /language/docs/*, /essays/* → /etc/essays/*, etc.
Updates nav-data.sx, all defpage routes, API endpoints, internal links
across 43 files. Enhanced find-nav-match for nested group resolution.
Also includes: page-helpers-demo sf-total fix (reduce instead of set!),
rebootstrapped sx-browser.js and sx_ref.py, defensive slice/rest guards.

Annotate all primitives in primitives.sx with (:as type) param types
where meaningful (67/80 — 13 polymorphic ops stay untyped). Add
parse_primitive_param_types() to boundary_parser.py for extraction.
Implement check-primitive-call in types.sx with full positional + rest
param validation, thread prim-param-types through check-body-walk,
check-component, and check-all. 10 new tests (438 total, all pass).

parse-comp-params now recognizes (name :as type) — a 3-element list
with :as keyword separator. Type annotations are stored on the
Component via component-param-types and used by types.sx for call-site
checking. Unannotated params default to any. 428/428 tests pass (50
types tests including 6 annotation tests).

Implements subtype checking, type inference, type narrowing, and
component call-site checking. All type logic is in types.sx (spec),
bootstrapped to every host. Adds test-types.sx with full coverage.

The cond special form misclassified Clojure-style as scheme-style when
the first test was a 2-element list like (nil? x) — treating it as a
scheme clause ((test body)) instead of a function call. Define
cond-scheme? using every? to check ALL clauses, fix eval.sx sf-cond and
render.sx eval-cond, rewrite engine.sx parse-time/filter-params as
nested if to avoid the ambiguity, add regression tests across eval/
render/aser specs. 378/378 tests pass.

Two bugs fixed:
1. process-bindings used merge(env) which returns {} for Env objects
(Env is not a dict subclass). Changed to env-extend in render.sx
and adapter-async.sx. This caused "Undefined symbol: theme" etc.
2. async-aser-eval-call passed evaled-args list to async-invoke(&rest),
double-wrapping it. Changed to inline apply + coroutine check.
Also: bootstrap define-async into sx_ref.py (Phase 6), replace ~1000 LOC
hand-written async_eval_ref.py with 24-line thin re-export shim.
Test runner now uses Env (not flat dict) for render envs to catch scope bugs.
8 new regression tests (4 scope chain, 2 native callable arity, 2 render).

The sync aser-call in adapter-sx.sx didn't flatten list results from
map/filter in positional children — serialize(list) wrapped in parens
creating ((div ...) ...) which re-parses as an invalid call. Rewrote
aser-call from reduce to for-each (bootstrapper can't nest for-each
inside reduce lambdas) and added list flattening in both aser-call
and aser-fragment.
Also adds test-aser.sx (41 tests), render-sx platform function,
expanded test-render.sx (+7 map/filter children tests), and specs
async-eval-slot-inner in adapter-async.sx.

- Add page-helpers-demo page with defisland ~demo-client-runner (pure SX,
zero JS files) showing spec functions running on both server and client
- Fix _aser_component children serialization: flatten list results from map
instead of serialize(list) which wraps in parens creating ((div ...) ...)
that re-parses as invalid function call. Fixed in adapter-async.sx spec
and async_eval_ref.py
- Switch _eval_slot to use async_eval_ref.py when SX_USE_REF=1 (was
hardcoded to async_eval.py)
- Add Island type support to async_eval_ref.py: import, SSR rendering,
aser dispatch, thread-first, defisland in _ASER_FORMS
- Add server affinity check: components with :affinity :server expand
even when _expand_components is False
- Add diagnostic _aser_stack context to EvalError messages
- New spec files: adapter-async.sx, page-helpers.sx, platform_js.py
- Bootstrappers: page-helpers module support, performance.now() timing
- 0-arity lambda event handler fix in adapter-dom.sx

EvalError moved to types.py. All 27 files updated to import eval_expr,
trampoline, call_lambda, etc. directly from shared.sx.ref.sx_ref instead
of through the evaluator.py indirection layer. 320/320 spec tests pass.

- evaluator.py: replace 1200 lines of hand-written eval with thin shim
that re-exports from bootstrapped sx_ref.py
- bootstrap_py.py: emit all fn-bodied defines as `def` (not `lambda`),
flatten tail-position if/cond/case/when to if/elif with returns,
fix &rest handling in _emit_define_as_def
- platform_py.py: EvalError imports from evaluator.py so catches work
- __init__.py: remove SX_USE_REF conditional, always use bootstrapped
- tests/run.py: reset render_active after render tests for isolation
- Removes setrecursionlimit(5000) hack — no longer needed with flat code

- Fix qq-expand in eval.sx: use concat+list instead of append to prevent
nested lists from being flattened during quasiquote expansion
- Update append primitive to match spec ("if x is list, concatenate")
- Rebuild sx_ref.py with quasiquote fix
- Make relations.py self-contained: parse defrelation AST directly
without depending on the evaluator (25/25 tests pass)
- Replace hand-written JSEmitter with js.sx self-hosting bootstrapper
- Guard server-only tests in test-eval.sx with runtime check
