Carriage return and backspace only MOVE the cursor; neither erases. Both of
my earlier approximations were wrong, and I checked each case against a real
terminal rather than reasoning about it:
`100%\rOK` shows `OK0%`, not `OK` — the redraw is shorter than the frame
beneath it, so the tail stands. `abc\b` still shows `abc`, not `ab` — a
trailing backspace has nothing to overwrite. `\x1b[31mgone\rkept` paints
`kept` RED, because a carriage return does not reset the graphic state, which
one of my own tests had asserted the opposite of.
Both now replay into a per-line column buffer with SGR state stamped per
column, as a terminal stores it per cell. That gives the partial-overwrite
case its real result too: red `bad`, three backspaces, then `ok` shows `okd`
with the `d` still red, since `ok` reached only two of the three cells.
The presenter description now also renders at every site. An expanded row
draws it itself — the collapsed summary is hidden while open, so otherwise
the description was visible only collapsed, the opposite of "above the card"
— and the details panel draws it above the card as well.
Three of my own tests encoded the wrong semantics and were corrected with
their behavior, and the emit loop's gap-filling arm was removed as
unreachable: `\r` and backspace only move left, so no column can be unwritten.
The pending question now owns exactly two surfaces: the redesigned
QuestionComposer takeover (footer pager, checkbox multi-select,
always-visible custom input, locale-injected bilingual chrome) collects
the answers, and a dedicated ask_user_question toolview row reports the
interaction outcome — waiting, N/M answered, cancelled (ASK_CANCELLED),
or interrupted with stopped semantics (ASK_ABORTED). PendingCard narrows
to approval waits only. Toolview leading icons and the hover chevron
unify on the tertiary label color, the checklist glyph matches the
14px figma extract, and dev-watch registers CSS modules so css-only
edits rebuild.
Four review findings. Two are defects the previous two rounds introduced,
which the existing tests did not catch:
A backspace erased raw bytes, so one landing after an SGR reset ate part of
the escape: `\x1b[31mabc\x1b[0m\b\bXY` left `\x1b[` and repainted the rest of
the line with whatever the remainder parsed as. Backspaces now resolve over
VISIBLE characters — a CSI sequence is one indivisible unit a backspace steps
over on its way to the last printed character, so the surviving text keeps
the color its run authored.
The cwd normalizer popped a UNC share root: `\\server\share` with a `..`
became `/server`, losing the separators too. A UNC path's server and share
are its root, and Windows cannot climb above a share, so they are split off
and the remainder collapses against that root.
The other two are gaps the earlier fixes left:
The render-site fallback row still passed the args-derived summary, so any
terminal-declaring tool without its own keyed row (`terminal_send`) lost the
contract's above-card description. It now prefers the description exactly as
BashRow does.
A settled call read `call?.cwd`, which cannot tell "the call omitted a cwd"
from "the paging window dropped the call head". The second case has no cwd
anywhere and the original call may have used an explicit workdir, so it now
draws a bare `$` instead of naming the session workspace.
Clearing waitingApprovals in handleConnected raced the reconnect replay:
mux frames flow from stream open while onConnected waits for the
readiness handshake, so a replayed approval/requested could land first
and be wiped — amber dot and answerable card lost until the next
generation. The sweep moves to generation death (onStateChange
'reconnecting'), before any next-generation frame can exist, and now
also drops buffered answerable frames (approval/question pairs) whose
dead-generation rpcIds could never be answered — a session instantiated
later no longer replays zombie takeover cards. session/queued buffering
already re-baselines per generation; this closes the same window for
the interaction frames.
A multi-line command repeated the cwd label on every prompt row, which
states something the view does not know: it carries ONE working directory —
where the call started — and a `cd` in the command moves later lines
elsewhere. `cd ~` then `ls` rendered both rows labelled with the session
workspace while `ls` actually listed the home directory.
The label now appears on the first row only, and later rows keep a bare `$`
so they still read as prompts. Same reasoning as the run-state dot: neither
a per-line directory nor a per-line exit status exists to report.
The built-bundle snapshot records the effect on fixture turn 60's two-line
command (`fixture echo done` becomes `$ echo done`).
A popup on a host command is not a second command — it is what that
command's BARE invocation does on this client. CommandContribution loses
hostBacked (contributions are pure client commands again; a host-name
collision fails loud, unchanged for /model), and the contract gains
CommandDecoration + command.decorate(): key = the HOST command name, no
catalog row, no claim participation. Dispatch consults decorations only on
the bare paths (menu pick / bare enter) after the host row resolves; space
and argued enter never see them — the two edges hostBacked had to guard
explicitly hold by construction in the decoration model. A decorated name
with no host row in the session's directory never fires (a decoration
cannot manufacture a command).
ui-permission switches register→decorate with zero behavior change
(options still read the permissions projection; a pick still submits
'/permission <preset>'). Specs rewrite to the decoration semantics: no
catalog row, bare-enter popup vs argued-enter host claim, space host
claim, no-host-row miss, unavailable fall-through, duplicate fail-loud.
Three review findings, each verified against the presentation contract:
The call view's `description` was dropped, so a presenter that authors one
(`terminal_send` declares `Terminal <id>`) lost the contract's above-card text
and the row fell back to an unrelated args-derived summary. It now rides the
same derivation and outranks that summary.
A relative workdir was concatenated but never normalized, while the bash
executor resolves it before running: with session cwd `/w/app` and workdir
`..` the command runs in `/w`, yet the card displayed the label `..`. The
resolved path now collapses `.`/`..` segments, drops a `..` that would climb
past a root the way a filesystem does, and keeps a Windows path's separators
since the value is only ever displayed.
`run_code` sub-dispatches carry no presenter views on the shipped wire —
`session.ts` folds `tool/code-dispatch(-start)` with null views and the host's
`viewFor` presents only top-level call/result events — so a nested bash call
cannot reach a terminal card. The existing test only passed by injecting views
that path cannot produce; it now says so, and a second arm pins the no-view
shape the wire actually delivers.
Restoring master's fixture also fixed the todo snapshot lane, which my earlier
merge had broken by dropping the projection support the todo dock reads. The
terminal sample turn moved ahead of the todo turn, because the standing plan
retires at the next `turn/start` and a turn appended after it emptied the dock.
The card props are now nested under `card` so a render site spreads exactly the
primitive's own surface, and the fixture reads each sample's authored exit
status instead of re-implementing the bash tool's `parseExitStatus`.
Selecting a preset from the hero pushed the session into the conversation
view: the /permission switch logs its command/run + command/done pair, the
pair folds into flow nodes, and the composerPhase predicate counted ANY
node as conversation — so the hero (composerPhase === 'blank') collapsed.
The host-side blank bit was already correct (sessionBlank = no turn/start;
knob events open no turn), but the client derives its phase from window
content, and command rows are log-only records, not conversation.
derivePhase's hasContent now excludes command nodes — the client mirror of
the host predicate. The knob events themselves never fold (not
surface-eligible), so the pair was the only leak. Covers /plan on the hero
identically (same lifecycle pair, same predicate).
Specs: the host blank spec pins the three knob events as standalone
events; a session spec drives the /permission pair through the live path
and asserts phase stays 'blank' while the command node renders.
TestWorkspaces.listDirectory now records the signal and passes it to the
installed stub, mirroring the production face, so cancellation
integration tests can observe or reject on a superseded scan instead of
the harness silently dropping it.
Supersession (newer navigation, path editing, closing, unmount) now
aborts the in-flight listing's request instead of only discarding its
result: the browser mints an AbortController per listing, the signal
rides the workspace face (IWorkspaces.listDirectory gains an optional
signal) onto the fetch carrier, and the Host scan stops with it (817's
cancellation chain). apps/cli keeps both picker packages as dependencies
so the documented one-row cordis.yml swap to the native backend resolves
at boot.
Every filesystem await in the browse scan (opendir and each read) now
races the signal through raceAbort, so a stalled network open/read stops
with a departed caller and an already-aborted request rejects even for
an empty level; the abandoned settlement is swallowed and an abandoned
open that still mints a handle is closed, never leaked. apiproxy maps an
aborted listing to the cancelled wire code, matching pickDirectory and
command.execute, instead of reporting a false internal failure. The
fixture spec call sites gain the wire signal argument the previous
commit's static lane flagged.
Escape canceling a path edit opened before any level listed relaunches
the home listing instead of stranding a blank picker (the editor had
superseded the initial request while parent was still null). The card's
height clamps to the viewport (min(420px, 100dvh - 32px)); header and
footer are flex-none and the columns scroll, so Open/Cancel stay
reachable on landscape phones and short embedded windows.
capability.list gains an optional AbortSignal threaded from the RPC
carrier's request signal (the pickDirectory pattern): a disconnected or
timed-out caller stops the opendir loop instead of the scan outliving
its caller, and the abort surfaces as its own reason rather than a
directory-unreadable dressing. boundedInsert rejects a full window's
at-or-beyond-tail candidate on one comparison and binary-inserts
retained candidates, so an oversized level no longer pays a window scan
per dirent.
The browse level now streams through opendir into a name-sorted window of
maxEntries + 1 candidates (boundedInsert), so memory stays O(maxEntries)
no matter how many children a directory holds and enterability probing
touches only windowed candidates; a windowed broken symlink is not
backfilled since the eviction already marks the level truncated.
schemastery joins the package's runtime dependencies (the source launcher
and isolated installs failed to resolve the value import). The
folder-error dialog's Choose again goes inert while the flow hole is
empty, and the withdrawal effect also keys on the open transition, so a
flow can never open over a hole nobody serves.
