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

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.

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

evaluator.py _sf_lambda used only expr[2] (first body expression) instead
of collecting all body expressions and wrapping in (begin ...) when multiple.
This caused multi-body lambdas to silently discard all but the first expression.
Rebuilt sx_ref.py with --spec-modules deps,router,engine,signals so the
router functions are available from the bootstrapped code. The test runner
already had _load_router_from_bootstrap() but it was falling back to the
hand-written evaluator (which has set! scoping issues) because the router
functions weren't in sx_ref.py. Now 134/134 eval+router tests pass.

Browser always evaluates in render context — _renderMode must be true

- JS platform: add renderActiveP/setRenderActiveB + RENAMES for

eval-list only dispatches to the render adapter when render-active? is true.
render-to-html and aser set render-active! on entry. Pure evaluate() calls
no longer stringify component results through the render adapter.
Fixes component children parity: (defcomp ~wrap (&key &rest children) children)
now returns [1,2,3] in eval mode, renders to "123" only in render mode.
Parity: 112/116 pass (remaining 4 are hand-written evaluator.py bugs).

client-side SX navigation via orchestration.sx error response handling
- Add trailing slash redirect (GET only, excludes /api/, /static/, /internal/)
- Remove blue sky-500 header bar from SX docs layout (conditional on header-rows)
- Fix 405 on API endpoints from trailing slash redirect hitting POST/PUT/DELETE
- Fix client-side 404: orchestration.sx now swaps error response content

Client-rendered islands were re-hydrated by boot.sx because
renderDomIsland didn't mark them as processed. Hydration read
empty data-sx-state, overwriting kwargs (e.g. path) with NIL.
Fix: mark-processed! in adapter-dom.sx so boot skips them.
New plan: marshes — where reactivity and hypermedia interpenetrate.
Three patterns: server writes to signals, reactive marsh zones with
transforms, and signal-bound hypermedia interpretation.

The ~sx-header island now shows the current page path (faded, after
the copyright) inside the copyright lake. Navigate between pages:
the path text updates via server-driven lake morph while the reactive

Also fixes Island &key param serialization in component-source helper.

Lake tag (lake :id "name" children...) creates server-morphable slots
within islands. During morph, the engine enters hydrated islands and
updates data-sx-lake elements by ID while preserving surrounding
reactive DOM (signals, effects, event listeners).
Specced in .sx, bootstrapped to JS and Python:
- adapter-dom.sx: render-dom-lake, reactive-attr marks data-sx-reactive-attrs
- adapter-html.sx: render-html-lake SSR output
- adapter-sx.sx: lake serialized in wire format
- engine.sx: morph-island-children (lake-by-ID matching),
sync-attrs skips reactive attributes
- ~sx-header uses lakes for logo and copyright
- Hegelian essay updated with lake code example
Also includes: lambda nil-padding for missing args, page env ordering fix

Islands survive hypermedia swaps: morph-node skips hydrated

dispose-islands-in skips hydrated islands to prevent premature cleanup.
- @client directive: .sx files marked ;; @client send define forms to browser
- CSSX client-side: cssxgroup renamed (no hyphen) to avoid isRenderExpr

- Island wrappers: div→span to avoid block-in-inline HTML parse breakage
- ~sx-header is now a defisland with inline reactive colour cycling
- bootstrap_js.py defaults output to shared/static/scripts/sx-browser.js
- Deleted stale sx-ref.js (sx-browser.js is the canonical browser build)
- Hegelian Synthesis essay: dialectic of hypertext and reactivity

- data-init boot mode for pure SX initialization scripts
- Jiggle animation on links while fetching
- Nav: 3-column grid for centered alignment, is-leaf sizing,
fix map-indexed param order (index, item), guard mod-by-zero
- Async route eval failure now falls back to server fetch
