Wrap `test_tractor_cancels_aio`'s `main()` in a
`trio.fail_after(9 * cpu_perf_headroom())` so a wedged remote
runtime can't hang the test forever. This is the blessed
anti-hang guard here bc `pytest-timeout`'s global cap is
intentionally off (it breaks `trio` under the fork backends,
per the `pyproject` NOTE).
The cap is generous + CPU-headroom-scaled bc it's an anti-hang
guard, not a perf assertion. Motivated by the
`._ria_nursery`-removal regression where a wedged ria-reaper
once hung this exact test indefinitely.

Step B2 of the `._ria_nursery` removal (issue #477; see
`ai/conc-anal/ria_nursery_removal_plan.md`). With the 2ndary
nursery gone (step B), the two nested error handlers in
`_open_and_supervise_one_cancels_all_nursery` collapse to one,
- the outer `except (Exception, BaseExceptionGroup,
trio.Cancelled)` existed to catch errors bubbling from the
old `._ria_nursery.__aexit__` reaper-group; that nursery no
longer exists.
- trace shows the outer handler's `raise` was already DEAD: the
inner handler records `errors[uid]` as its first action, so
`errors` is always non-empty by the time anything could reach
the outer handler, and the `finally`'s raise-from-`errors`
always superseded the outer `raise`.
- so fold both into a single `except BaseException as
_scope_err` guarding the lone daemon nursery; the `finally`
(unchanged) still raises the collected `errors` as a single
exc or `BaseExceptionGroup`.
- drop the now-unused `outer_err`/`inner_err` locals.
Behaviour-preserving (net ~30 lines lighter); the big diff is
the one-level de-indent of the handler body. The two remaining
`maybe_wait_for_debugger()` guards collapse to the single
pre-teardown wait.

Step B of the `._ria_nursery` removal (issue #477; see
`ai/conc-anal/ria_nursery_removal_plan.md`). With step A having
rerouted `.run_in_actor()` children onto the daemon nursery,
the 2ndary "run-in-actor" nursery spawns nothing and its stored
ref is never read — pure dead weight,
- collapse the inner `async with trio.open_nursery() as
ria_nursery` layer in
`_open_and_supervise_one_cancels_all_nursery`; `da_nursery` is
now the single nursery for ALL subactors.
- `ActorNursery.__init__` loses the `ria_nursery` param + the
`self._ria_nursery` attr; `start_actor()` loses its `nursery=`
escape-hatch (spawns via `self._da_nursery` directly).
- `._cancel_after_result_on_exit` stays — still the ria-child
discriminator for `_reap_ria_portals()`.
Behavior-preserving: a zero-task `trio.open_nursery()` only adds
a checkpoint. The two error handlers are KEPT (now nested under
the single nursery); merging them changes error/cancel
propagation and is deferred to its own PR (TODO left at the
outer `except`).

Step A of the `._ria_nursery` removal (issue #477 follow-up, see
`ai/conc-anal/ria_nursery_removal_plan.md`): `.run_in_actor()`
children now spawn via the default daemon nursery and their
result-reaping moves up into the `ActorNursery` machinery,
- new `_supervise._reap_ria_portals()`: one
`_spawn.cancel_on_completion()` task per ria child, run AFTER
`._join_procs` is set — replacing the per-child reaper task the
backends formerly spawned (keyed off
`._cancel_after_result_on_exit` membership) which required
routing such children into `._ria_nursery`.
- happy path: reap awaited right after `._join_procs.set()`,
preserving "collect ria results before daemon join" sequencing.
- error path: snapshot ria `(portal, subactor)` pairs (backend
`finally`s pop `._children` as procs reap), `await an.cancel()`,
THEN a 0.5s-bounded reap over the snapshot; anything collectable
is already queued in the local ctx and a parked reaper
self-cleans (`trio.Cancelled` results are never stashed). NB: a
concurrent reap+cancel variant deadlocked `test_multierror` and
a 3s bound blew `test_cancel_while_childs_child_in_sync_sleep`'s
deadline — deats in the plan doc's probe history.
- `spawn/_trio.py` + `spawn/_mp.py`: drop the membership branch,
per-child reaper nursery + now-unused `cancel_on_completion`
imports; the join phase is a bare `soft_kill()`.
`._ria_nursery` is now vestigial (zero spawn users): step B
deletes it + `start_actor()`'s `nursery=` escape hatch and merges
the supervisor's two error handlers.

- the concurrent "worker-pool-ish" prime-check pattern: a local

First cut at the `to_thread`/`to_process`-style "run it over there"
wrapper layer from issue #477: a single-remote-task invocation API
decoupled from the `ActorNursery` spawn machinery, composed purely
from the lower level daemon-actor + portal primitives,
- `to_actor.run(fn, **fn_kwargs)` spawns a subactor via
`ActorNursery.start_actor()`, schedules `fn` as its lone task
with `Portal.run()` and ALWAYS reaps it via a `finally`-scoped
`Portal.cancel_actor()` (whose bounded cancel-req wait is
internally shielded so the reap also runs under caller-scope
cancellation).
- remote errors raise directly in the caller's task as boxed
`RemoteActorError`s, moving error collection/propagation up into
whatever local `trio` scope encloses the call.
- "placement" opts: `portal=` reuses a running actor (no
spawn/reap), `an=` spawns from a caller-managed actor-nursery,
neither opens a private call-scoped `open_nursery()` (implicitly
booting the runtime, tunable via pass-through `runtime_kwargs`).
- fail-fast validation BEFORE any spawn: non-streaming async fn
only (same constraint as `Portal.run()`), `portal=`/`an=` mutual
exclusion and no `runtime_kwargs` alongside a placement opt.
Also,
- x-ref the successor API from `.run_in_actor()`'s deprecation TODO
+ docstring; emitting a formal `DeprecationWarning` waits on
migrating in-repo usage.
- log prompt-io provenance per NLNet policy incl. the driver prompt

Copilot's 2nd-pass review (PR #468) caught a regression I landed in
the uds fix: `UDSAddress.get_random()` put the per-call token AFTER
`@{pid}` (`no_runtime_*@{pid}.{token}.sock`), which breaks the
`tractor._testing._reap` matcher
`^(?P<name>.+)@(?P<pid>\d+)\.sock$` — so no-runtime orphan socks
stopped matching and never got reaped/attributed. Move the token
INTO the name (`{prefix}.{token}@{pid}.sock`) so the canonical
`@{pid}.sock` suffix stays intact for both that regex and the
`spawn._reap` reconstruction; also bump the token to 8 hex chars.
Also two robustness nits from the same review,
- `tests.conftest._measure_sustained_headroom()`: guard `frac <= 0`
before `1./frac` — a 0/parked-core freq read would
`ZeroDivisionError`, get swallowed by the broad `except` into a
1.0 (no-throttle), defeating the probe on the exact broken box it
should flag; read 0 as max throttle.
- `scripts/cpu-perf-check`: mark the burn procs `daemon=True` and
wrap sampling in `try/finally` so a Ctrl-C / error reaps them
instead of leaving stray CPU hogs.

Finish TODO #2 from PR #468: the last raw `cpu_scaling_factor()`
call-sites still used the static-only check (blind to the
sustained-load power-cap). Point them at the `cpu_perf_headroom()`
SUPERSET — it calls `cpu_scaling_factor()` internally + the
session-cached throttle probe, so it's always >= the old factor
(never LESS headroom, so CI stays green).
Migrated,
- `test_spawning`: the `fail_after(1 * ...)` smoke deadline
(#465-added).
- `test_inter_peer_cancellation`: `this_fast` budget.
- `test_docs_examples`: example-run `timeout`.
- `test_resource_cache`: fan-out `timeout`.
`test_cancellation` already used `cpu_perf_headroom()`; only its

W/o a live runtime `get_random()` named UDS socks purely by
`(prefix, pid)`, so two calls in one proc returned the SAME
`no_runtime_*@{pid}.sock` — the 2nd `.bind()` then tripped
`EADDRINUSE`. Append a per-call `uuid4().hex[:6]` token so
each call yields a distinct sockpath.
This fixes the 3 `tests.discovery.test_tpt_bind_addrs` uds
failures (one registrar + disjoint-bind, two non-registrar
binds) where `reg_addr` and a "random" bind addr aliased —
the uds CI job's only red, surfaced when this branch rebased
onto the newer base that carries those tests.
Scoped to the no-runtime branch ON PURPOSE: the runtime
`{name}@{pid}` convention stays deterministic so
`spawn._reap.unlink_uds_bind_addrs()` can still reconstruct
+ unlink a SIGKILL'd subactor's sock (#454).
Deats,
- `_uds.py`: add `uuid4` import + token in the no-runtime
branch
- `_testing.addr`: tighten `get_rando_addr()` docstring re the
intra-proc per-call token (not just pid-keyed namespacing)

Both `_burn()` impls (the `cpu-perf-check` script + the
`_measure_sustained_headroom()` probe in `tests.conftest`) grew `x`
~x**2 per iter, so the loop quickly went bigint alloc/mul-bound — a
noisy CPU load + needless memory across N procs. Mask each step to
64-bit for a steady, fixed-width ALU burn (still pegs every core,
which is all the freq probe needs).
Also, `_read_mhz()` opened the sysfs freq files without a ctx-mgr;
`with open(...)` so the FD closes deterministically (matches the
script's own `_read()`).

`cpu_perf_headroom()` is a strict SUPERSET of `cpu_scaling_factor()`
— it folds in static cpu-freq scaling + the slow-CI bump AND the
sustained-load power-cap throttle probe. Point the timing-deadline
call sites at it so they're robust to sustained throttling too (the
gremlin behind mass `trio` deadline-miss flakes),
- `test_legacy_one_way_streaming`: `time_quad_ex` cancel-deadline +
`test_a_quadruple_example`'s `this_fast` smoke bound.
- `test_cancellation`: `test_cancel_via_SIGINT_other_task` +
`test_fast_graceful_cancel_*` deadlines.
`cpu_perf_headroom >= cpu_scaling_factor` always, so never less
headroom (CI stays green); `cpu_scaling_factor()` remains the
internal static component.

Standalone CLI companion to `cpu_perf_headroom()` (20cb99ec): idle
freq snapshots LIE — every static knob (`governor`, EPP,
`platform_profile`, `scaling_max_freq`) can read "performance"
while a firmware/EC power cap (AMD PPT/STAPM + friends) clamps the
package to ~30% the moment a sustained multi-core load lands,
masquerading as a `trio`-backend deadline-miss "regression" on
byte-identical code.
Deats,
- burns every core for `CPU_PERF_SECS` (default 4s) and samples the
ACHIEVED `scaling_cur_freq` steady-state (post boost-ramp) vs the
package max ceiling,
- exits 0 when the sustained fraction clears
`CPU_PERF_HEALTHY_FRAC` (default 0.45), 1 when throttled — so it
gates a suite run: `scripts/cpu-perf-check && pytest tests/ ...`,
- prints the static knobs first (to show they all read fine) then
the remediation list on failure (`platform_profile` bounce, USB-C
PD replug, `ryzenadj`, reboot) w/ the key reminder: do NOT bump
test budgets — the box is slow, not the code.

Mass `trio` deadline-miss failures on byte-identical code turned
out to be a firmware/EC power-cap (AMD PPT/STAPM) clamping the
all-core sustained clock while every static knob (`governor`,
`scaling_max_freq`, EPP, platform-profile) still read "performance"
— invisible to the existing `cpu_scaling_factor()` check. See
`scripts/cpu-perf-check` + the
`ai/conc-anal/trio_033_cancel_cascade_slowdown_depth3_issue.md`
notes.
Deats,
- add `_measure_sustained_headroom()` to `tests/conftest.py`: a
one-shot ~0.9s all-core burn (explicit `fork`-ctx `mp` procs)
sampling achieved-vs-max freq AFTER the boost window; under a 0.6
gate it returns the full inverse fraction (capped 4x), else 1.0;
best-effort 1.0 on non-linux or any error,
- add `cpu_perf_headroom()`: `max()` of the static scaling factor
and the (session-cached) sustained probe,
- inflate deadline budgets by it in `test_dynamic_pub_sub`, both
`test_clustering` cases, the
`test_multi_nested_subactors_error_through_nurseries` pexpect
waits + `test_nested_multierrors`,
- `xfail(strict=False)` `test_nested_multierrors` depth=3 under
throttle: the deep tree trips tractor's INTERNAL reap deadlines
(`soft_kill`/`hard_kill` `terminate_after=1.6`) minting a
`Cancelled` inside the runtime — not fixable by test-budget
inflation; auto-clears once the box un-throttles.

`uds_transport_actor_tree.py` (new in 759d46dd) reliably fails on
macOS CI with a bare `returncode 1`. The example forces
`enable_transports=['uds']`, and UDS-on-macOS is otherwise
un-exercised by the matrix (there's no `tpt_proto=uds` macOS job),
so it's the first thing to surface a macOS UDS-path issue.
It passes cleanly on Linux, and the peer-cred paths are already
platform-guarded + graceful (`get_peer_info`/SO_PEERCRED on linux
vs `get_peer_pid`/LOCAL_PEERPID elsewhere) - so the crash is deeper
in the macOS UDS stack. The test swallows the subproc stderr (only
re-raises when the last line has "Error"), so the exact failure
can't be pinned from CI logs; needs a macOS box to root-cause.
Skip it on `_friggin_macos and ci_env` (same shape as the existing
`full_fledged_streaming_service` skip) so #460 lands green; the
macOS UDS root-cause is a follow-up.

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.

The reworked `we_are_processes.py` (now `Context`-API based) prints

stale: swap the old `Yo, i'm 'worker_N'...` / "self-destruct in 1

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()`

The README inlined six example scripts; per our own "point at

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`

`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

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.

Capture the (easy-to-forget) logo recolour + theme-preview flow,
- new `notes_to_self/svgtool.py`: a headless-firefox svg helper
(`colors`/`recolor`/`preview`/`page`); its `page --theme
dark|light` injects a `localStorage` pin so a pydata `auto`-mode
build renders its dark variant in a screenshot — the only way to
verify theme-adaptive bits headlessly,
- `howtodocs.md`: a "Tweaking the logo" table (which file +
`color:` knob per context) and an `svgtool` section that breaks
down the `--theme` trick for the sphinx-rusty.

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.

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.

Collect the sphinx build + live-preview one-liners (incl. the nix
`.#docs` opt-in shell and the `d2` diagram specifics) so
contributors don't have to reverse-engineer them,
- new `notes_to_self/howtodocs.md` terse cheat-sheet (force-added
past the `notes_to_self/` ignore, same as `howtorelease.md`),
- a rendered "Building these docs" section in the dev-tips guide
(`docs/project/dev-tips.rst`),
- a README pointer to the note.

The `docs` group (sphinx 9 + `pydata-sphinx-theme` stack) was added
to `pyproject.toml` but its lockfile half never landed — the
committed `uv.lock` still matched `main` and `uv lock --check`
flagged it out-of-sync. Relock to add the (additions-only) docs
deps so `uv sync --locked` and any CI lock-check pass.

The new `api/` reference pages surfaced 22 docutils warnings from
informal reST in public docstrings; fix the markup so the docs
build is warning-free (24 -> 0), clearing the path to a future
`-W`/`nitpicky` flip in CI.
Deats (docstring content only; no code/signature changes),
- give bullet lists a blank line + base-column indent (`Context`,
`Context.cancel_called`/`.cancelled_caught`/ `.outcome`,
`ActorNursery.cancel_called`, `query_actor`,
`open_crash_handler`),
- demote the under-short `Behaviour:` underline in `Context.cancel`
to a `**bold**` label,
- close an unbalanced backtick in the `wait_for_actor` summary and
use the `` `role`\ s `` escaped-plural idiom where a role was
pluralized (`gather_contexts`, `mk_pdb`, `MsgCodec`, msg `Error`,
`open_context_from_portal`),
- make the `|_` method-tree in `ContextCancelled.canceller` a
literal block (the bare `|` was read as a substitution ref),
- same blank-line fix for the `#318` entry in `NEWS.rst`.

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.

Factor the shared dev-shell toolchain into `basePkgs` + `baseHook`
so extra-tooling shells can extend it, then add a `docs` shell =
base + `pkgs.d2` (the diagram renderer our `.. d2::` sphinx
directive shells out to). Keeps `d2` OUT of the `default` shell so
casual dev envs stay lean.
Enter with `nix develop .#docs`, then build via `uv run --group
docs make -C docs html`.

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.

`docs.yml`: sphinx build on PRs + main pushes (via `uv sync
--no-dev --group docs`), deploying to gh-pages only from main
pushes using the official
`actions/{upload-pages-artifact,deploy-pages}` pair - the
`msgspec`-style flow wished for in #123. No `d2` bin in CI (yet) so
the committed SVGs serve as-is.

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 +
#126.

grayscale theme, `elk` layout) w/ their pre-rendered fallback SVGs
committed under `docs/_diagrams/` (served as-is when no `d2` bin is
found, eg. in CI),
- `actor_tree`: the hero supervision-tree,
- `context_handshake`: seq diagram of the
`Start`/`StartAck`/`Started`/`Yield`/`Stop`/`Return` ctx dialog,
- `streaming_pipeline`: 4-actor fan-in topology,
- `runtime_stack`: the per-actor layer cake,
- `debug_lock`: root-tty-lock REPL serialization,
- `error_propagation`: one-cancels-all boxed-err flow,
- `infected_aio`: guest-mode loop nesting.

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.

Theme choice per the #157 research: `numpy`, `ray` + `polars` all

New runnable (and so CI-auto-tested) scripts backing the new docs
guides, each following the `test_docs_examples.py` runner
conventions,
- `typed_payloads.py`: `@tractor.context(pld_spec=)` typed
`started()`/stream roundtrip + a deliberate `MsgTypeError` catch
demoing send-side validation,
- `nested_actor_tree.py`: 3-level tree w/ fan-out rpc through a
mid-tier supervisor actor,
- `service_daemon_discovery.py`: registered daemon located via
`find_actor()`/`wait_for_actor()` sans any spawn-portal ref,
- `uds_transport_actor_tree.py`: `enable_transports=['uds']` tree
printing the filesystem sockaddr + kernel peer-pid creds,
- `streaming_broadcast_fanout.py`: one ipc stream fanned out to N
local tasks via `MsgStream.subscribe()`.
All gaps were mined from in-code TODOs + the docs recon pass; see
#175 for the orig tutorial wishlist.

Rename `parallelism/_concurrent_futures_primes.py` ->
`concurrent_futures_primes.py` so the example-runner
(`test_docs_examples.py`) stops skipping it (leading `_` =
excluded) and CI finally exercises the `concurrent.futures`
baseline we compare against in the new parallelism guide.
Deats,
- keep the original executor code verbatim in a sync
`check_primes()` fn for clean docs excerpting,
- add module docstring + zero-arg `async def main()` +
`trio.run(main)` guard per the runner conventions.

Swap the deprecated `portal.result()` calls for the modern
`.wait_for_result()` spelling in,
- `a_trynamic_first_scene.py` (x2)
- `actor_spawning_and_causality.py`
- `parallelism/single_func.py`
These 3 are literalinclude'd by the new docs tree so the rendered
code must teach the current api; the `debugging/` set still calls
`.result()` (pexpect pattern-matched tests, left for a follow-up
sweep).

The `.uid`->`.aid` migration (prior commits) re-assembled the
legacy uid pair by hand as `(x.aid.name, x.aid.uuid)`.
`Aid.uid` (`msg/types.py`) is the non-deprecated canonical
property returning exactly that pair, so swap to `x.aid.uid`
everywhere — byte-identical, just DRY + consistent.
Covers the 5 review-flagged source sites (`msg._ops`,
`devx.debug._sync`, `experimental._pubsub`, `_exceptions`)
plus the ~22 unflagged identical sites (`_streaming` f-string
logs + 6 test modules); also tightens the `_exceptions`
`our_uid` annotation to `tuple[str, str]`.

Ports below 1024 are privileged on linux
(`net.ipv4.ip_unprivileged_port_start = 1024`), so a non-root
`.bind()` on one raises `PermissionError`. The old `1000 +` floor
could roll into the 1000-1023 range and trip flaky `[Errno 13]
Permission denied` registry-listener binds; bump the base to 1024
so every generated port is non-privileged.
