Merge tutorial/ch07-clock: Chapter 7 ("The Clock")
A logical Clock actor (callers advance via :tick) plus a
BikeShare.Rider extended with pickup_at and an :elapsed handler.
The chapter argues for logical clocks over now() for both
testability and WASM compatibility (now() in the WASM build is
stubbed to 0). Solution passes 7/7 in CLI and WASM.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

feat(tutorial): chapter 7 -- The Clock
Adds 07-clock.md and the ch07_clock exercise. A simple Clock
actor with one Int field that callers advance via :tick. The
BikeShare.Rider from Chapter 6 grows pickup_at and a guarded
:elapsed handler that reports how long the rider has had the bike.
The chapter explains why the clock is logical (callers send :tick)
rather than wall-clock: WASM's now() returns 0, and even a working
wall clock would make tests flake. Pattern is the same one used
by Erlang/OTP and most distributed systems for testable time.
Three TODOs:
- Clock's :tick (the canonical "increment counter, reply new value"
shape from earlier chapters)
- Rider's guarded :pickup, now threaded with a Clock arg, capturing
the pickup time into pickup_at via a multi-field become whose
right-hand side is a `clock <- :now` send
- Rider's guarded :elapsed, computing (clock <- :now) - pickup_at
Solution passes 7/7 in CLI and WASM. Stub Exercise hints are
prose-only; no commented-out answer code under any TODO.

feat(tutorial): chapter 6 -- The Rider
Adds 06-rider.md and the ch06_rider exercise. Introduces a
BikeShare.Rider actor that holds one user's session: name and a
Bike slot that's nil when idle.
New language ground:
- nil as a meaningful state value
- == nil and != nil guards on multi-clause handlers
- the pre-flight check pattern (send to downstream, dispatch on
the reply, only commit your own state if downstream confirmed)
Three TODO handlers; the multi-clause :pickup and :return get
their fallback clauses pre-wired so the reader's work is the
guarded "do the thing" clauses. The rider also lives at
BikeShare.Rider so each instance is its own supervision boundary
under the same prefix as Vault and Inventory from chapter 5.
Solution passes 7/7 in CLI and WASM.

docs(tutorial): rewrite ch3-5 step sections with parallel examples
The "Step N: fill in X" sections used to lead with the exact answer
in a code block, then walk through it line by line. That made the
exercises a copy-paste rather than a synthesis, and the "Putting it
together" recap blocks doubled the answer count.
New shape: each step shows the language pieces in small parallel
patterns (a Counter that takes a typed arg, a Stack that pops the
head, an integer-list reduce, a divide-by-zero bubbler) and asks
the reader to compose the actual handler from those parts. The
exercise file's solution stays the canonical assembled answer.
Also folded the standalone "Sending messages from inside a handler"
section in ch3 and "Sending into a closure" section in ch4 into the
steps that needed the concept, since they were duplicating ground

Merge tutorial/ch05-supervision: Chapter 5 ("The supervision tree")
Introduces bubble / orelse / bubbles(CascadeBubble) and the dotted-name
supervision tree. Exercise wires a BikeShare parent to a Vault and an
Inventory; the vault bubbles on overdraw, the parent translates the
bubble into a tagged tuple, and an :emergency handler cascades a reset
across every BikeShare.* sibling at once. Solution passes 5/5 in CLI
and WASM.

feat(tutorial): chapter 5 -- The supervision tree
Adds 05-supervision.md and the ch05_supervision exercise.
Introduces three new pieces of language ground:
- bubble :reason raises a failure that propagates as a value
- target <- :msg orelse X catches a bubble at the call site
- bubbles(CascadeBubble) handler annotation: when this handler bubbles,
restart every dotted-name sibling under the
same supervisor prefix
The exercise builds three cooperating actors: a BikeShare.Vault that
holds cents, a BikeShare.Inventory that holds a bike count, and a
BikeShare parent that wires them together. Three TODOs:
- :withdraw bubbles :overdraw on insufficient funds
- :charge translates the bubble into {:error, :declined} via orelse
- :corruption is annotated bubbles(CascadeBubble) so a panic resets
every BikeShare.* sibling
Solution passes 5/5 in the CLI and in the tutorial WASM evaluator.
The chapter walks through bubble vs. tagged tuple as a design choice
(state preserved vs. erased), the dotted-name supervision boundary,
and the bulkhead pattern of unrelated supervisor prefixes never
cascading into each other.

fix(ws): use the correct RFC 6455 magic GUID for Sec-WebSocket-Accept
The handshake constant in builtins.zig had the magic GUID's hex
digits scrambled:
258EAFA5-E914-47DA-95CA-5AB9DC80CB65 (wrong)
258EAFA5-E914-47DA-95CA-C5AB0DC85B11 (RFC 6455 §1.3)
curl doesn't validate Sec-WebSocket-Accept against the locally
computed expected value, so handshakes from curl saw the 101 and
the WS frames started flowing -- the chat *looked* like it worked.
Real browsers do validate, and rejected every connection with
"Incorrect 'Sec-WebSocket-Accept' header value", which is why
Enter on the chat input never actually delivered: the WS was never
open, the form fell through to its HTTP POST fallback, and the
page reloaded.
Fixes the GUID, fixes the test that was calibrated to match the
bug (it now expects the RFC 6455 example value
"s3pPLMBiTxaQ9kYGzzhZRbK+xOo=" for key "dGhlIHNhbXBsZSBub25jZQ=="),
and adds a deploy snippet to infra/README.md for rebuilding and
shipping the chat interpreter.
Verified end to end on the live box: handshake response now
matches the RFC value, and a headless-Chrome session through
https://blimp.bobbby.online/chat/ logs in, types a message, hits
Enter, and sees the message broadcast back via WebSocket without a
page reload.

Merge chat/fix-ws-handshake: WebSocket handshake now follows RFC 6455
The ws_accept_key builtin was using a corrupted magic GUID, which
curl's loose handshake check let slide but every real browser
correctly rejected. Fixes the constant, fixes the test that was
calibrated to the bug, and documents the rebuild/redeploy steps

chat: serve at blimp.bobbby.online/chat/ via Caddy reverse proxy
Three changes to chat.blimp so it works behind a path-stripping
proxy:
- Form actions become relative ('/login' -> 'login', '/send' ->
'send') so they resolve against whatever URL the page is at.
- Redirects use './' so the browser stays under the /chat/ prefix
instead of jumping to root.
- The WebSocket URL is now built from window.location, including
protocol (wss when the page is HTTPS) and the current pathname
prefix.
Also adds infra/Caddyfile + infra/README.md, which are the live
contents of /opt/blog/Caddyfile on the Hetzner box. The
blimp.bobbby.online block now redirects bare /chat -> /chat/ and
reverse-proxies /chat/* to 172.18.0.1:8080 (the blog_default
docker-bridge gateway, where the blimp-chat systemd service is
listening on the host's 0.0.0.0:8080).
Verified end-to-end: GET /chat/ serves the login HTML, POST
/chat/login redirects with a session cookie, GET /chat/ws does
the WebSocket upgrade and immediately receives the broadcast
frame.

Merge chat/path-aware: chat lives at blimp.bobbby.online/chat/
chat.blimp uses relative URLs (form actions, WebSocket, 302
redirects) so it works behind a path-stripping reverse proxy.
Caddy on the Hetzner box now proxies /chat/* on blimp.bobbby.online
to 172.18.0.1:8080, where the blimp-chat systemd service is
listening. Adds infra/Caddyfile + infra/README.md so the proxy
config is tracked alongside the source.

feat(tutorial): chapter 4 -- Zoom out
Adds 04-zoom-out.md and the ch04_zoom_out exercise. Introduces
anonymous functions (`fn(x: T) do ... end`) and the three list
builtins that take them as arguments: map, filter, reduce. The
chapter's exercise builds a `BikeShare` actor that holds a list of
`Station` references and fans questions (total bike count, names of
busy stations) out to all of them via map / filter / reduce.
Three TODO handlers (`:open`, `:total_bikes`, `:busy_stations`).
Solution passes 7/7 in CLI and in WASM.
The original ch4 roadmap said "supervision tree, dotted names, zoom
out". This chapter takes the "zoom out" half of that and ch5 will
take supervision + dotted names. Updated 00-why-actors.md's roadmap
to reflect the split, and updated the ch5 placeholder title in the
SPA chapter list.
Implementation note: at this zoom level Stations track bikes by an
integer counter rather than by holding [Bike] actor references. A
runtime hang shows up when actor refs are passed as typed message
args into actors that later get iterated by a parent's
closure-send; we work around it here, will revisit alongside ch5.

Merge tutorial/ch04-zoom-out: Chapter 4 ("Zoom out")
Anonymous functions, map/filter/reduce, and a `BikeShare` parent
actor that fans questions out to a list of `Station` children.
Seven tests; solution passes in CLI and WASM.
Splits the original ch4/ch5 roadmap: ch4 takes "zoom out", ch5
takes the supervision tree + dotted names + crash isolation
material, including a runtime hang to fix where actor refs passed
as typed args interact badly with closure iteration.

Sweeps the tutorial chapters so identifiers (Bike, DockingStation,
String, status, id) render monospaced wherever they appear in prose,

Adds 03-actors-talking.md and the ch03_actors exercise (stub +
solution). Introduces a DockingStation actor that holds a list of
Bike references and orchestrates rentals: list-typed state, the
cons / head / tail / length pattern, typed message arguments
((b: Bike)), and sending messages to other actors from inside a
handler. Exercise has 8 tests; the solution passes all 8 in the CLI.
Wires ch03 into the SPA's chapter list so the tutorial picks up the
new markdown, stub, and solution files automatically.

feat(tutorial): replace textarea editor with Monaco
Drops Monaco (v0.46.0 from jsdelivr) into docs/tutorial/index.html in
place of the layered textarea + <pre> highlight overlay. Registers a
`blimp` Monarch grammar mirroring blimp-highlight.js (same keywords,
constants, builtins, atoms, #{} interpolation, PascalCase types) and a
`blimp-dark` theme matching the existing token colors so highlighting
stays visually consistent with the static code blocks rendered in the
middle pane.
Cmd/Ctrl+Enter is now a Monaco command bound to Run Tests. The cheat
tab and rendered markdown blocks keep using blimp-highlight.js (small,
sync, no behavioral change). Boot does Promise.all([blimp.init,
initMonaco]) before loading the first chapter.

feat(tutorial): SPA with embedded REPL, test runner, and Blimp highlighter
Adds docs/tutorial/index.html, a single-page tutorial viewer. Three-pane
layout: chapter rail on the left, rendered markdown in the middle,
interactive REPL pane on the right. URL fragment (#ch00, #ch01, etc)
drives chapter navigation, fetches the chapter's markdown, loads the
matching exercise stub into the editor, and runs the reader's code
against the WASM-compiled Blimp runtime via the new `runTests()`
binding. Failures show up inline with structural detail captured from
the assertion builtin. "Cheat" tab fetches the solution .blimp file
from disk and highlights it; "Copy to editor" paves over the stub.
Also adds blimp-highlight.js, a zero-dependency syntax highlighter for
Blimp. Keyword list is derived from chunks/lang/tree-sitter-blimp/
grammar.js plus Zig-parser extras (test, property, given, if, else) so
it stays in sync with the real grammar. Handles string interpolation
(#{...}), atoms, numbers, operators, keywords, builtins, and type-like
capitalized identifiers. Used for code blocks in rendered chapter
markdown, the live editor textarea (layered <pre> overlay with scroll
sync), and the cheat-view solution display.
exercises/ lives at the repo root so CLI users can run `blimp test
exercises/...`. For the web tutorial, docs/tutorial/exercises is a
symlink to ../../exercises so the SPA fetches work from a single path
both locally and in production; deploy.sh follows the symlink via
rsync -L.

feat(tutorial): bike share tutorial chapters 0-2 and first exercises
Builds a TDD-driven Blimp tutorial that teaches the actor model by
constructing a bike share simulation one actor at a time. Twelve
chapters planned total; this commit lands the first three:
- Chapter 0: why actors, the dispatcher-with-clipboard mental model,
functional core / imperative shell as the organizing philosophy,
and the piecemeal progression the rest of the chapters follow.
- Chapter 1: your first actor. A Bike with id and status, four
handlers filled in one at a time. Walks through actor templates,
state defaults, the `::` assignment operator, atoms as interned
symbols, spawn-with-overrides, the `<-` send operator, and why
`become` exists (Hewitt's original actor primitive, not mutation).
- Chapter 2: state, become, and the free lock. Multi-clause handlers
with guards, tagged `{:ok, ...}` and `{:error, ...}` tuples, a third
`:broken` state that drops in without any type edits, and the
punchline of the chapter: why an actor's mailbox plus "handlers
run to completion" gives you mutual exclusion without any locks.
Each chapter has a matching exercise file in exercises/chNN_topic/
with a stub the reader fills in, failing tests that progressively
go green, and a reference solution in solutions/.
Voice: one-sentence-per-line markdown, no em-dashes, piecemeal
concept-then-exercise flow, design decisions traced back to the
deciduous graph and docs/lang_design/ where they were made.

feat(chat): poll-based server loop, read WS frames end-to-end
Replace the blocking accept_loop with a poll-based loop that watches
[server_fd | all_ws_fds]. When a WS fd is ready, read one frame and
route {"type":"msg","from":..,"text":..} to the room, then broadcast.
HTTP POST /send path preserved as a fallback for WS-less clients.
Also fixes extract_quoted's off-by-one: Blimp evaluates args such that
char_at(s, idx) in a call alongside idx+1 sees the post-incremented
idx. Compute char_at into a local first. Same pattern may need the
same treatment wherever it appears (json_escape_loop, slice_idx);
not swept in this commit.
TODO: step 3 of the bidirectional-WS plan still has 'from' coming
from the client frame instead of a server-side session lookup.
