Add a runnable `examples/dedicated_registrar.py` + a "A dedicated
registrar" subsection in `guide/discovery.rst` demoing the
registrar decoupled from any app tree's root: boot a bare
`tractor.run_daemon([], registry_addrs=[...])` as its own process
(a root actor that does nothing but hold the registry), point the
app tree at the same `registry_addrs`, and discover a service
*through* that external registrar.
This is the buildable-today form of the #472
"Registrar-as-subsystem (not the root actor)" bullet. Two
constraints are called out inline as follow-ups:
`enable_transports` is single-proto per runtime (no multi-backend
registrar yet), and a registrar can only be a root (no `actor_cls`
hook on `start_actor()` to spawn one as a subactor).

The "Toward capability-based msging" section only pointed at the
`#196`/`#36` epics. Fold in the concrete recent state,
- `#365` as the most recent step: driving the whole `pld_spec` off
plain type-annotations (e.g. annotating a context's
`open_stream()` with `msgspec.Struct` subtypes) rather than
explicit `pld_spec=` kwargs.
- clarify that the decorator-level `@tractor.context(pld_spec=...)`
is already the higher-level path (vs the lower-level
`tractor.msg._ops.limit_plds()` escape hatch), pointing at
`tests/msg/test_pldrx_limiting.py` + `test_ext_types_msgspec.py`
which exercise both.
- `#376` (from @guilledk, `auto_codecs` branch) as the drafted
public factory API for the `enc_hook`/`dec_hook` pair (today only
reachable via `tractor.msg._ops`).
Addresses the caps-based-msging bullet in #472.

The `context_handshake` sequence diagram only showed the graceful
`Return` ending - underselling the whole SC pitch (errors + cancels
propagate *both* ways across the wire). Add a "... or, instead of a
graceful Return" group with the non-graceful endings,
- parent-initiated: `ctx.cancel()` (or a parent-side error) ->
child relays `Error: ContextCancelled`,
- child-initiated: child ships `Error: <raised>` (or
`ContextCancelled`).
Labelled `Error: ...` since `ContextCancelled` is an exception that
rides inside an `Error` wire msg, not its own msg type - keeping
the diagram's wire-level labels honest. Re-render the committed
`_diagrams/context_handshake.svg` fallback (CI has no `d2` bin) to
match.
Also cache-bust d2 images in `d2diagrams.py`: sphinx tags css/js
with `?v=<hash>` but not images, so an edited diagram kept serving
the browser's stale copy at the stable `_images/<stem>.svg` url
(cost us a manual hard-refresh). Hash each rendered svg + rewrite
only the d2 `<img src>` to `...svg?v=<hash8>` via the
`html-page-context` hook - content-addressed, so unchanged diagrams
keep their query.

Continuing the README slim-down: stop inlining content that now
lives (and renders better) on the GitHub Pages site, and just
point readers there.
- "Where do i start" drops the SC reading-list links in favor of
a single nudge to the docs quickstart.
- "Example codez" drops the full `we_are_processes.py` listing -
keep the one-minute pitch prose + the docs/examples links.
- "What's on the TODO" collapses the inline bullet list down to a
link to the docs roadmap ("what the future holds").
Also,
- prune the now-dead RST link targets (`blog post`, `trio docs`,
`SC`, `libdill-docs`, `async sandwich`, `messages`, ..).
- swap the `|docs|` badge from readthedocs over to the GitHub
Pages `docs.yml` action badge + `goodboy.github.io` target.

The reworked `we_are_processes.py` (now `Context`-API based) prints
different stdout, so the hardcoded expected-output block went
stale: swap the old `Yo, i'm 'worker_N'...` / "self-destruct in 1
sec" lines for the real run - "self-destruct in 2s.." then the
per-worker `Started ep-task in subactor,` / `N::'worker_N'@<pid>`
blocks.
Also retell the prose to match: subs spawn concurrently from bg
`trio` tasks, each runs a `@tractor.context` `endpoint()` that
`ctx.started()`-hands its name + pid back through
`Portal.open_context()`, then parks in `trio.sleep_forever()`
before the root crashes + the tree is reaped.

The README inlined six example scripts; per our own "point at
`examples/`, don't duplicate" philosophy that's a lot of rot
surface. Drop all but the showcase and rework it onto the modern
`Context` API to mirror the docs landing + `we_are_processes.py`:
spawn a subactor per core, `open_context()` each, crash the root,
reap the tree.
Replace the rest with a short "want more?" pointer to the docs site
+ the `examples/` dir (where the debugger, streaming, cancellation,
`asyncio`, msging + cluster demos all live, CI-run).
Also tidy a few nits while here,
- fix the title typo "structurred" -> "structured",
- close the unterminated quote in the `UV_PROJECT_ENVIRONMENT`
install snippet,
- add the blank line a nested `trionics` bullet list needs so the
PyPI long-desc (this file) renders as valid RST.

`run_in_actor()` is slated to become a hilevel wrapper
(`runtime/_supervise.py` "TODO: DEPRECATE THIS"), so the showcase
`we_are_processes.py` shouldn't lead with it. Move it to the modern
API: each `worker_<i>` subactor runs a `@tractor.context`
`endpoint()` that `started()`-hands its name + pid back over
`Portal.open_context()` and parks; the root sleeps then raises on
purpose so the runtime reaps the whole tree (zero zombies).
The subs spawn concurrently from bg `trio.Task`s so each child's
cold `import tractor` (~0.4s, see #470) overlaps instead of
stacking; a comment flags the coming `main_thread_forkserver`
backend (#463) which'll make serial spawns cheap enough to just
loop.
Match the landing prose to the snippet — name the `Context` +
`started()` handshake it now leads with.
Also, document `--watch examples` on the `sphinx-autobuild` cmds so
edits to `literalinclude`-d example scripts (which live outside
`docs/`) live-reload too.

The gh-pages deploy workflow already exists (build on PR + main,
deploy on main push via `actions/deploy-pages`); wire up the sphinx
side,
- `sphinx.ext.githubpages`: emits a `.nojekyll` so Pages serves the
`_static/` + `_images/` dirs (Jekyll otherwise drops `_`-prefixed
paths, breaking every asset),
- `html_baseurl`: the canonical site root
(`https://goodboy.github.io/tractor/`) for the `<link
rel="canonical">` + `og:url` tags.
The one remaining (one-time, manual) step is the repo setting:
Settings -> Pages -> Source = "GitHub Actions".

Rework the landing top into a left-anchored hero row and match the
navbar branding to it.
- `index.rst` + new `tractor_hero.html`: an inline-svg hero
(`[logo] distributed structured concurrency`) with a full-width
sub-tagline, plus a single screen-reader-only `<h1>` ("tractor")
so the section headings become proper `<h2>` (was 4x `<h1>`), and
the intro prose reflowed into 3 bullets,
- `conf.py`: a `logo.text` ("tractor") beside the navbar wireframe,
polars-style,
- `custom.css`: the hero-row layout (logo + tagline + sub-line,
single row on desktop / stack on mobile), the navbar brand styled
like the centered nav tabs with `display:inline-block` to kill
the parent link's propagated hover-underline, and smaller landing
section headings w/ their `tl;dr` margin-note pulled level.
The hero linework stays `fill: currentColor` so the whole thing
flips with the light/dark toggle.

Carry the landing hero's transparent-faces wireframe look to the
two other logo contexts. An `<img>`-embedded svg can't read the
page CSS (no `currentColor`), so the colours are baked per target,
- navbar: 2 variants (`tractor_logo_nav_light.svg` near-black
lines, `…_nav_dark.svg` near-white) wired via the pydata
`logo.image_light`/`image_dark` opts so it swaps with the theme
toggle, matching the hero,
- README: `tractor_logo_wire.svg` — one neutral-grey, with INLINE
fills (no `<style>`) so it reads on both GitHub light + dark and
survives GitHub's svg sanitiser.
Faces are `fill: none` throughout; the filled `tractor_logo_side`
stays the recolour source + favicon.
(this patch was generated in some part by [`claude-code`][claude-code-gh])
[claude-code-gh]: https://github.com/anthropics/claude-code
Swap the landing-page hero from a static `<img>` (white-faced —
which glared as a light box on the dark theme) to an INLINE svg
whose linework uses `fill: currentColor` and whose faces are
transparent. The wireframe now inherits the theme text colour
(`svg.hero-logo { color: var(--pst-color-text-base); }`) and the
page background shows through, so it flips correctly with the
light/dark toggle.
- `tractor_logo_hero.html`: the inline svg partial (`.st0` ->
`currentColor`, `.st1` -> `none`), `.. raw:: html :file:`-d into
`index.rst`,
- the shared `tractor_logo_side.svg` is untouched here (navbar +
favicon still ride it).

Add a "Share on your LAN" blurb to both docs how-to homes
(`notes_to_self/howtodocs.md` + the dev-tips "Building these docs"
section): bind the server to all ifaces — via `sphinx-autobuild
--host 0.0.0.0` (live-reload) or `python -m http.server --bind
0.0.0.0` (static) — so a peer on your subnet can hit
`http://<lan-ip>:8000` (`hostname -I` prints the ip).
Verified a LAN-ip `curl` returns 200 + the socket binds `0.0.0.0`;
includes a trusted-LAN-only caveat since it's an unauthenticated
server on every interface.

Three robustness fixes surfaced by the PR #460 self-review,
- a render that's *attempted and fails* (a `d2` bin is present but
errors on the source) now raises a docutils error instead of
silently serving the stale committed SVG — so `sphinx-build -W`
fails on a broken `.d2` edit. The no-binary case stays a quiet
committed-SVG fallback.
- render into a sibling temp-file then `os.replace()` so a
failed/torn render can never clobber a good committed SVG.
- guard against 2 distinct `.d2` sources colliding on a single
`_diagrams/<stem>.svg` within a build.
`render_svg()` now returns a `RenderResult` tristate that `run()`
maps to error / raw-source-literal / image.

Address the actionable findings from the `/code-review` pass
(#1-6); the d2-ext + docstring nits (#7-10) are left for a
follow-up.
Deats,
- `uds_transport_actor_tree.py`: `portal.chan.raddr.sockpath` is
the *shared listener* socket (named for the root registrar), NOT
the child's path — relabel it + lead with the per-child peer pid,
and stop claiming it's the child addr in the docstring,
- `docs.yml`: scope the `pages` `concurrency` group to the `deploy`
job w/ `cancel-in-progress: false` so a PR build can't cancel an
in-flight production deploy,
- `architecture.rst`: `'subint'` is not a selectable `start_method`
on this branch (`SpawnMethodKey` lacks it) — reframe as
in-development/roadmap,
- `context.rst`: `StreamOverrun` isn't re-exported from `tractor`;
point at `tractor._exceptions`,
- `debugging/`: sweep the 3 literalinclude'd examples off the
deprecated `.result()` -> `.wait_for_result()`,
- `quickstart.rst`: proc-title is `name@pid` (per `Aid.reprol`),
not `@uuid`.
NOTE, the `debugging/` examples are pexpect-tested; re-run
`tests/devx/test_debugger.py` for them.

Replace the ancient `docs/index.rst` (still teaching
`tractor.run()`, `@stream` + arbiters..) with a full ~32 page tree
teaching ONLY the current api (`.wait_for_result()`, registrar
naming, `@context` + `open_context()` as the core model),
- landing: hero example, feature cards + canon links,
- `start/`: install + a 4-example quickstart on-ramp,
- `explain/`: an "SC across processes" essay distilling the essence
per #157's orig ask + a runtime architecture tour,
- `guide/`: 12 task-focused pages incl the flagship multi-process
debugging walkthrough, `Context` + `MsgStream` deep-dives,
cancellation semantics (self-vs-cross cancel rules), discovery,
infected `asyncio`, typed msging + the #126 testing-tips page,
- `api/`: 10 curated autodoc pages (all targets import-verified vs
the reorg'd subpkg tree),
- `project/`: changelog include, ported dev-tips (drops old
`docs/dev_tips.rst`) + roadmap.
Every code block is a `literalinclude` from `examples/`
- zero duplication, all CI-run - w/ `d2` figs floated
into the RHS margin per the 3-col design. Build is green; the 24
remaining warnings all source from lib docstring rst-isms or legacy
`NEWS.rst` content.
Substantially resolves#157 (refine round pending); chips at #175 +

Full `docs/conf.py` rewrite targeting `pydata-sphinx-theme` 0.18
(3-col layout: nav-index left, content middle, page-toc right)
skinned to a minimal b&w look via `_static/css/custom.css`, keeping
the `algol_nu` pygments style.
Also add 2 local sphinx exts under `docs/_ext/`,
- `d2diagrams.py`: a `.. d2::` directive rendering `d2lang` sources
at build time when a `d2` bin is found (`D2_BIN` env supports
argful values eg. `'nix run nixpkgs#d2 --'`), falling back to any
git-committed SVG, else emitting the raw source as a literal
block; no pypi ext was usable (all stubs or returncode-swallowing
per the #157 research),
- `marginalia.py`: a theme-agnostic `.. margin::` directive
(`sphinx-book-theme` style `Sidebar` subclass) for prose-anchored
RHS asides; the custom css floats these (and `:margin:` d2 figs)
into the right gutter on wide screens.
