Implement the calendar/clock half of #9 as plain-i32 integer epochs — no
new type, no floating point (the issue's "integer epochs to avoid drift") —
so every operation is deterministic and bit-identical on every platform:
Duration — a span in whole seconds; seconds/minutes/hours/days build one,
as_seconds/as_minutes/as_hours/as_days read it back. Because a
duration is just an int, `+` and `>` work with no extra machinery
(Duration.minutes(5) + Duration.seconds(30), away > Duration.hours(3)).
Date — a civil day as days-since-1970 (UTC): new/year/month/day/weekday/
is_leap/days_in_month/to_epoch/add_days/diff_days.
DateTime — an instant as seconds-since-1970 (UTC, matching Time.now):
from/date/add/year/month/day/weekday/hour/minute/second.
Time.since(past) = now - past, for offline-progress / "time away" checks.
New selfhost/emit_datetime.ludic (is_/emit_ for the three namespaces, wired
into emit_ns_call + the frag list). The two civil<->epoch conversions are
Howard Hinnant's public-domain proleptic-Gregorian algorithms, emitted once
per program as the @fn_days_from_civil / @fn_civil_from_days prelude and gated
by g_uses_datert; days_in_month is next-month-day-0 (no lookup table). Time
gains `since`. Docs (Duration/Date/DateTime sections, 28 method pages +
time-since), inventory, and LSP hover kept in sync; a registered test checks
component math against hand-computed values. Reseeded; C-free fixpoint holds;
all suites green (26 self-host / 45 regression / 29 tools); check.py,
check-impl.py and validate.py OK.
format/parse, a game-controlled simulated clock, and timezones are tracked
follow-ups; v1 is UTC-only and, on the i32 epoch, valid through 2038.

Expand the abbreviated pointer types to full words on the language surface:
ptr -> pointer (a raw address / FFI handle)
ptrs -> pointers (a buffer of pointers)
The Ludic type name is distinct from LLVM's own `ptr` spelling: llty() maps
`pointer`/`pointers` to LLVM `ptr`, and the emitted IR keeps `ptr`, so only
the Ludic-level surface changes. Rewrites type annotations across all
sources, the 8 hardcoded pointer type-tags, the `pointers`-buffer indexing
in emit_addr, the grammars/LSP/JetBrains tokens, and the docs
(type-ptr -> type-pointer, type-ptrs -> type-pointers). int/bool keep their
conventional short spelling (like Math).
Reseeded; C-free fixpoint holds; all suites green (45/24/29); site + check.py OK.

Expand the function-declaration keyword to the full word across the whole
language and toolchain:
fn name(...) -> T { ... } -> function name(...) -> T { ... }
Done as a self-hosting migration: teach the parser both spellings, reseed,
rewrite every .ludic definition to `function`, then drop `fn`. The compiler
now rejects `fn`. Touches the parser, all selfhost/tools/runtime/example/test
sources, the grammars (TextMate shared+vscode, ludic_syntax.h, JetBrains
LudicTokens.kt), the LSP and formatter, the Python doc/vocab tools
(check-impl, check-docs, validate, palette, test-lsp), and the docs
(fences, prose, kw-fn -> kw-function).
Reseeded; C-free bootstrap fixpoint holds. All suites green (45 regression,
24 self-host, 29 tool); the docs site generates and check.py passes.

Implement the bulk of the namespaced-stdlib proposal (workshopsoft/ludic#2):
156 namespace methods across Math, Text, List, Ease, Collide, World, Net,
Sys, Save, Mem, extended Screen, Color functions, extended Random, and Time.
All deterministic fixed-point; self-hosting (C-free bootstrap fixpoint holds).
Compiler (selfhost/):
- Math.*: sqrt/sin/cos/tan/atan2/asin/acos (fixed-point runtime prelude —
bit-by-bit isqrt, 256-entry interpolated sine table, Ross atan2), plus
hypot/dist/dist2/deg_to_rad/rad_to_deg/posmod/wrap/ping_pong/snapped/
move_toward/smoothstep/lerp/remap/sign/floor/ceil/round.
- Text.* (complete): upper/lower/trim/repeat/pad, split/join/replace,
and the libc-backed queries.
- List.* (complete): insert/remove_at/remove/sort plus the earlier ops.
- Ease.* (in/out/in_out/back/bounce) and Collide.* (rects/point_rect/
circles/rect_circle).
- Phase 3: World/Net/Sys/Save namespaced over the bare builtins (byte-
identical IR) and Mem.* (bytes/words/copy/fill/peek/poke).
- Screen.* extended (line/circle/fill_circle/triangle/fill_triangle via new
runtime primitives; sprite/sprite_scaled aliases), Color.* functions,
Random.* (value/int/sign), Time.* (frame/delta/elapsed/now — new
game-loop frame counter).
- Fix a lexer bug: fixed-point literals with >4 fractional digits overflowed.
Docs & tooling:
- 129 new per-symbol doc pages; gen.py made data-driven (namespaces
discovered from the docs, no hardcoded list); new check-impl.py enforces
that every implemented namespace method / keyword / type / phase has a
doc page, wired into `x test-tools`. Document the previously-undocumented
keywords (break/continue/where/entry/new/public + and/or/not tokens).
- LSP: namespaced signature help (ns_method_sig) covering every namespace.
Tests: 12 new self-host/regression tests + a golden render for the drawing
primitives. All suites green (selfhost 21, regression 45, tools 29).
