* docs: fix ascii-guard border alignment errors
Three docs pages had ASCII diagram boxes with off-by-one column
alignment issues that failed docs-site-checks CI:
- architecture.md: outer box is 71 cols but inner-box content lines
and border corners were offset by 1 col, making content-line right
border at col 70/72 while top/bottom border was at col 71. Inner
boxes also had border corners at cols 19/36/53 but content pipes
at cols 20/37/54. Rewrote the diagram with consistent 71-col width
throughout, aligned inner boxes at cols 4-19, 22-37, 40-55 with
2-space gaps and 15-space trailing padding.
- gateway-internals.md: same class of issue — outer box at 51 cols,
inner content lines varied 52-54 cols. Rewrote with consistent
51-col width, inner boxes at cols 4-15, 18-29, 32-43. Also
restructured the bottom-half message flow so it's bare text
(not half-open box cells) matching the intent of the original.
- agent-loop.md line 112-114: box 2 (API thread) content lines had
one extra space pushing the right border to col 46 while the top
and bottom borders of that box sat at col 45. Trimmed one trailing
space from each of the three content lines.
All 123 docs files now pass `npm run lint:diagrams`:

Pre-existing failures on main — unrelated to any open PR.
* test(setup): accept description kwarg in prompt_choice mock lambdas
setup.py's `_curses_prompt_choice` gained an optional `description`
parameter (used for rendering context hints alongside the prompt).
`prompt_choice` forwards it via keyword arg. The two existing tests
mocked `_curses_prompt_choice` with lambdas that didn't accept the
new kwarg, so the forwarded call raised TypeError.
Fix: add `description=None` to both mock lambda signatures so they
absorb the new kwarg without changing behavior.
* test(matrix): update stale audio-caching assertion
test_regular_audio_has_http_url asserted that non-voice audio
messages keep their HTTP URL and are NOT downloaded/cached. That
was true when the caching code only triggered on
`is_voice_message`. Since bec02f37 (encrypted-media caching
refactor), matrix.py caches all media locally — photos, audio,
video, documents — so downstream tools can read them as real
files via media_urls. This applies to regular audio too.
Renamed the test to `test_regular_audio_is_cached_locally`,
flipped the assertions accordingly, and documented the
intentional behavior change in the docstring. Other tests in
the file (voice-specific caching, message-type detection,
reply-to threading) continue to pass.
* test(413): allow multi-pass preflight compression
run_agent.py's preflight compression runs up to 3 passes in a loop
for very large sessions (each pass summarizes the middle N turns,
then re-checks tokens). The loop breaks when a pass returns a
message list no shorter than its input (can't compress further).
test_preflight_compresses_oversized_history used a static mock
return value that returned the same 2 messages regardless of input,
so the loop ran pass 1 (41 -> 2) and pass 2 (2 -> 2 -> break),
making call_count == 2. The assert_called_once() assertion was
strictly wrong under the multi-pass design.
The invariant the test actually cares about is: preflight ran, and
its first invocation received the full oversized history. Replaced
the count assertion with those two invariants.
* docs: drop '...' from gateway diagram, merge side-by-side boxes
ascii-guard 2.3.0 flagged two remaining issues after the initial fix
pass:
1. gateway-internals.md L33: the '...' suffix after inner box 3's
right border got parsed as 'extra characters after inner-box right
border'. Dropped the '...' — the surrounding prose already conveys
'and more platforms' without needing the visual hint.
2. agent-loop.md: ascii-guard can't cleanly parse two side-by-side
boxes of different heights (main thread 7 rows, API thread 5 rows).
Even equalizing heights didn't help — the linter treats the left
box's right border as the end of the diagram. Merged into a single
54-char-wide outer box with both threads labeled as regions inside,
keeping the ▶ arrow to preserve the main→API flow direction.
- add ACP user and developer docs covering setup, lifecycle, callbacks,
permissions, tool rendering, and runtime behavior
- add developer guides for agent loop, provider runtime resolution,
prompt assembly, context caching/compression, gateway internals,
session storage, tools runtime, trajectories, and cron internals
- refresh architecture, quickstart, installation, CLI reference, and
environments docs to link the new implementation pages and ACP support
