Subject: [PATCH 01/15] fix: restore fmt and refresh size/swallowed-error
 budgets on 7c6975496

Master tip 7c6975496 fails its own Format and Quality Guardrails
checks: 15 files carry rustfmt drift (app-core server/timing,
jcode-core stdin_detect, ratatui-core span/fast, tui status_tests,
cloud_runtime) and the swallowed-error plus test-size ratchets fell
behind current source. Same recipe as the maintainer's own 025d8793e
fix, applied against the current tip.

Subject: [PATCH 02/15] fix: pass mutable winsize pointer to openpty in pty
 tests

libc 0.2.191 declares openpty with *mut winsize; the pty test helper
passed a null const-pointer and a shared reference, so the jcode-tui
test build fails to compile on the current master tip.

Subject: [PATCH 03/15] tests: fix host-dependent asserts after upstream drift

- rendering.rs: upstream added token counts to file_activity rows, update
  the render assert to the new expected text
- frame_flicker.rs: copy badge label is platform-dependent (opt glyph on
  macos), assert via copy_badge_alt_label() instead of a literal
- idle_hibernation.rs: 'private mem' notice only renders when the host
  exposes process memory snapshots (linux/windows); keep that assert
  conditional on measurement availability so the frozen-frame test
  passes on macos too

Subject: [PATCH 04/15] tests: fix app-core/base/cli reds on 7c6975496

- prompt_tests: DEFAULT_SWARM_PROMPT grew to 1041 bytes with b82768c61's
  coordination guidance, raise the stale 600-char budget to 1200
- platform_tests: use getsid(2) on a live detached child instead of
  parsing 'ps -o sid=' which does not exist on BSD ps (macOS)
- session_tests: scope the pmset streaming-assertion checks to this
  process, an ambient jcode daemon legitimately holds assertions
- tool/tests: exempt macos_computer_use and the new todo/session_search
  params from the token caps, matching the existing exemption pattern
- browser.rs: restore intent_schema_property() in the browser schema,
  a5a17469f's trim left a bare {type: string} and broke the display-only
  intent guard
- compile_remote: skip the non-utf8 filename test when the filesystem
  itself refuses invalid-UTF-8 names (APFS)
- client_lifecycle_tests: message 78 carries user-shaped content, so
  e6d9cb47c runs it as a real turn and the invalid skill terminal-errors
  instead of the old Done replay suppression
- browser_session_tests: measure responsiveness from the confirmed
  stall, daemon spawn cost on a loaded host must not count
- provider_init_tests: clear ambient JCODE_OPENROUTER_*/profile env and
  third-party compatible provider keys so auto-detect stays isolated
- commands_tests: a bare IP is loopback-like since #2018, pin the new
  requires_api_key contract
- onboarding_flow: guard JCODE_INITIAL_PROVIDER_EXPLICIT the same way
  the strongest-model unit test does, an agent session exports it and
  it leaks into the first-run preference assert

Subject: [PATCH 05/15] fix(tui): expire half-held OSC reports on inactivity,
 not total time

A fragmented OSC 11 reply (ESC ] 11;rgb: ...) can take longer than the
250ms stray-input timeout to spell out its whole introducer over ssh or
a slow pty. Expiry measured from the first held byte, so the half-built
report was replayed as ordinary keys (bare Esc, ']', digits) before it
could finish; the pty test caught it because the synthesized theme
Resize never became the first event.

Track when the last report byte was held and measure the window from
that. A stalled fragment still replays on the same short clock, so a
genuine lone Escape outside a query is not delayed. The recognized
REPORT_TIMEOUT path is unchanged.

Subject: [PATCH 06/15] fix: satisfy clippy and budget gates on the 7c6975496
 tip

Upstream tip is red across its own quality guardrails under the current
stable toolchain. The workspace lints vendored ratatui-core/-widgets, so
its new clippy findings block everything:

- ratatui-core buffer.rs: drop the redundant & in the Debug impl; the
  current clippy flags it as useless_borrows_in_formatting
- ratatui-core span.rs: clippy now exempts deprecated methods from
  wrong_self_convention, so the three #[expect]s are unfulfilled and
  fail under -D warnings; drop them. The ASCII fast path slices per
  byte, which string_slice flags, but is_printable_ascii guarantees
  each byte is a standalone char; allow it at the binding with the
  invariant stated
- ratatui-widgets paragraph.rs: b7ca4ec91's direct row blit removed the
  last UnicodeWidthStr use, drop the dead import
- ratatui-widgets sparkline.rs: use checked_div for the zero-max guard
  with the original evaluation order preserved
- ratatui-widgets reflow.rs: truncate(0) is now manual_clear, use clear
- jcode-voice: allow type_complexity on the focused-session cache
  static, same pattern as the four existing allows in the workspace

Budgets: the tip also drifted past its own ratchets. Refresh
warning_budget.txt (0 -> 32) and the test-size baselines for the five
test files the earlier fixes grew; both are mechanical --update runs,
the deltas are upstream's own code plus the test guards this branch
adds.

Subject: [PATCH 07/15] fix: clear the remaining clippy gate findings on the
 7c6975496 tip

The tip's clippy gate fails on three fronts under the current stable
toolchain; this clears them all so the workspace passes cargo clippy
--all-targets --all-features -- -D warnings with zero findings and the
cargo-check warning count drops to zero.

- transcript_search: 25 needless borrows on the search-shard arguments,
  mechanical clippy --fix
- tui_state: redundant closure replaced by the function path
- app-core: drop the child_pid binding c5c6ad890 orphaned, take the
  format_error_chain path directly, and unwrap schedule_queued_retry's
  vestigial loop whose body always returns
- companion: allow too_many_arguments on terminal_command_from_parts,
  same as the three existing allows elsewhere
- binary_watch: allow needless_return on ensure_started, the early
  return is the once-only guard and clippy misreads the cfg block below
  as the function tail
- communicate: mark the three coordination predicates dead-code-exempt
  outside tests; 92ca1819a inlined their production use and the unit
  tests keep them pinned
- cloud_git: the probe loop helpers are cfg(not(test)) so nothing
  reaches them in the test build, exempt dead_code there only
- session picker preview path: the live layout rework orphaned several
  helpers while the preview tests kept calling them (draw/draw_widgets/
  draw_preview_input and the per-source preview loaders); exempt
  dead_code outside tests for those, plain allow for the ones the rework
  orphaned outright, and restore the markdown/raw-excerpt re-exports as
  cfg(test) imports the tests actually use
- canvas/filter: move the impl blocks above their test modules so no
  items sit after a cfg(test) module, keeping the cfg attrs intact
- ui_prepare: the too_many_arguments expect sat above the wrong fn
  (a doc comment separated it from shrink_wrapped_lines); reattach it
  to wrap_lines_with_map
- tests: apply the cloned_ref_to_slice_refs and clone_on_copy
  suggestions, drop the fully-specified AccountPool's needless struct
  update
- budgets: re-pin warning_budget to 0 (all 32 warnings were these
  findings) and refresh the size ratchets the new attribute lines grew

Subject: [PATCH 08/15] fix: gate unix-only code paths behind cfg(unix) for the
 windows targets

CI compiles the workspace for x86_64/aarch64-pc-windows-msvc; four unix
patterns leaked past the cfg surface on the tip and failed those jobs:

- jcode-voice dictation: the niri IPC socket fast path uses
  std::os::unix::net::UnixStream without a cfg, so the windows targets
  failed E0433. Gate the helper and its call like the neighboring
  send_transcript_blocking already does.
- cli cloud_managed_tests: the linux-only shell fixture module uses
  Path, but the import lived at file scope where the mac clippy sweep
  (which does not compile the module) read it as unused. Restore the
  import gated to the module's own cfg.
- jcode-base auth transfer: cloud_store/identity_hints/cloud_expiry are
  only reached from cfg(unix) blocks; dead on windows, so gate them.
- jcode-base cloud_environment: Write is only used by the unix staging
  paths; import it cfg(unix) so the windows build has no unused import.
- jcode-base mcp oauth: secret_options mutates only on unix; move the
  binding inside the unix branch so windows sees no needless mut.

Subject: [PATCH 09/15] refactor: move unix cloud transfer helpers into a
 cfg(unix) module

The cfg gates on the four cloud-store helpers let the windows targets
compile, but transfer.rs is a code-size-budget tracked file that may not
grow, and the attrs pushed it over the ratchet. Move the helpers into a
unix-only child module so the gates live once on the module instead of
per fn, and the oversized file shrinks (2185 -> 2112 LOC). Callers are
unchanged; helpers keep their signatures and are pub(super) re-imported.

Subject: [PATCH 10/15] make session picker preview transcript test hermetic
 against the changelog updates box

the test asserted no picker metadata (including box borders) in the
preview transcript, but the startup header renders an Updates box
from unseen changelog entries, which on a fresh CI runner is always
non-empty (no last_seen_changelog state file). take the render-state
lock and force the unseen entries override to empty, matching the
pattern already used by the other render tests

Subject: [PATCH 11/15] keep the picker transcript test inside the test-size
 budget

the hermeticity fix added 6 lines to an already-oversized tracked
test file, tripping the test-size ratchet. extract nothing, just reuse
the production line_plain_text helper instead of an inline span-join
closure and tighten the comment; net line count back to the baseline

Subject: [PATCH 14/15] chore(budgets): align ratchet baselines with green base

The branch carried pre-uplift baseline values for the size and safety
budgets. Restore the refreshed baselines from fix/master-green-2100
(933444f3f) so only this branch's own growth needs accounting.

Subject: [PATCH 15/15] chore(budgets): refresh ratchet baselines for this
 branch

Absorb the branch's own intentional growth into the size and safety
budget baselines, following the same pattern as the base's refresh
commit. Floors now match the branch's current tree, so the ratchet
still blocks any further growth.
