The session.new default keybindings included 'mod+n' and 'shift+n',
which fired when users typed uppercase N (Shift+N) or accidentally
pressed Ctrl+N while using an IME to type Chinese — silently creating
new sessions mid-conversation.
Remove both combos so New Session is only reachable via the sidebar
button. Ctrl+Shift+N (session.newWindow) is unaffected.
- use-keybinds: bail out of the global keydown dispatcher while an IME
composition is active. Windows Chinese IMEs use Ctrl+, as their
punctuation toggle, which also matched nav.settings and navigated away
mid-word — destroying the unsent composer draft (#41079).
- use-composer-draft.test: regression-pin the unmount-stash/remount-restore
contract so route navigation (Settings) can never again drop an unsent
draft with the React tree.
- use-composer-actions.test: the bounded-preview pipeline keys attachments
to the durable path and resolves thumbnails asynchronously; the dropped-
screenshot test now asserts the durable-path contract instead of the
retired full-res previewUrl field.
Addresses review feedback on #68744: downscaling inside
attachmentPreviewDataUrl made previewUrl the 2048px PNG, but current main
(d8cb73b4ab) feeds that field to ImageLightbox and useImageDownload, so
large attachments would open and download at reduced resolution.
- attachmentPreviewDataUrl returns the full-resolution data URL again
- ComposerAttachment gains thumbnailUrl?: string (store/composer.ts)
- attachImagePath stores previewUrl (full-res) + thumbnailUrl (downscaled)
- Attachment pill renders thumbnailUrl ?? previewUrl; lightbox/download
keep the full-res previewUrl
- optimisticAttachmentRef prefers thumbnailUrl for the in-flight bubble
display ref (same main-thread decode freeze at send time)
- Attachment-level regression test in use-composer-actions.test.ts:
full-res previewUrl preserved while thumbnailUrl is a separate
downscaled value (4000x3000 -> 2048x1536)
- Add submitting state + IME composition guard to prevent double-submit
- submitEdit() sets latch, then clears after 200ms timeout
- handleKeyDown() guards on composing so IME Enter doesn't submit
- Shift+Enter inserts newline without submitting
- Test validates Enter calls onEdit, latch clears for second session
Fixes#70771

The inline edit composer caps height at max-h-48 but had no overflow
rule, so long prompts were clipped with no way to reach the tail.
Add overflow-y-auto to match the main composer editor.
The mapper test pinned the sessions column count (54, then 55, then 56
within one week as git_metadata_generation and the hidden flag landed).
Every ordinary column addition broke it. Derive max_fields from
PRAGMA table_info at runtime with a >= floor so the test keeps asserting
the rebuild contract without change-detecting the schema width.
The salvaged branch predates the electron test project's node:test -> vitest
migration (test:desktop:platforms is now `vitest run --project electron`).
Import `test` from vitest so the suites are collected; assertions stay on
node:assert/strict per the existing electron test convention.
Addresses both review findings on the remote-gateway download PR:
1. Unbounded buffering (finding #1). fetchBuffer / fetchBufferViaOauthSession
accumulated the entire response (then copied it again via Buffer.concat)
before saveGatewayFile even opened the save dialog, so a large gateway file
could exhaust the native process. Both auth paths now stream: once response
headers arrive the connect timeout is cleared, the filename is derived, the
save dialog is shown, and the body is piped to the chosen destination with
backpressure. A read/write error tears down the stream and unlinks the
partial file. The byte-moving, data-URL decoding, and filename/path helpers
are extracted into gateway-file-download.ts so they're unit-testable without
Electron.
2. No fallback for older gateways (finding #2). saveGatewayFile required the new
/api/fs/download route. Desktop and the remote gateway update independently,
so a gateway predating this PR 404s. Added a 404-only compatibility fallback
to the existing capped /api/fs/read-data-url route (bounded, so it only
serves smaller files — enough to keep older backends working).
Tests: gateway-file-download.test.ts covers streaming, backpressure,
error-cleanup (unlink on write/response error), data-URL decoding, filename
derivation (incl. traversal reduction), and 404 detection;
gateway-file-download-transport.test.ts asserts both transports stream (no
whole-body Buffer.concat) and that the 404 fallback is wired. Both registered
in the desktop platform test list. Server-side /api/fs/download tests
(streaming + sensitive-file reject) already pass.

- The readonly-loader completer test now stubs
get_portable_mcp_server_names_nowait — real plugin discovery runs
load_config() during one-time process init, which is not the
per-keystroke read the test guards against.
- Cap _resolve_toolset_memo at 256 entries: generation-keyed entries
from stale generations are never hit again, so clear on overflow to
keep long sessions bounded.
_file_mutation_verifier_enabled and _turn_completion_explainer_enabled
re-read config.yaml on every call via load_config() (~1ms deepcopy per
call). finalize_turn runs these gates at the end of every turn, so each
turn paid two redundant config deepcopies. The sibling
_credits_notices_enabled already caches on self; mirror that pattern.
The env-var override stays authoritative and uncached, so runtime flips
still work. Config flips now apply on the next session, matching the
documented sibling semantics.

resolve_toolset() recursively walks toolset includes and, with
include_registry=True, merges registry-registered tools on every call —
each external call re-runs the includes walk and takes a fresh registry
snapshot under the registry lock. It is called dozens of times per
_get_platform_tools() (every /tools completion keystroke, per picker
render) and at 19 call sites across the CLI/gateway.
Memoise the external-entry result keyed on (name, include_registry,
registry id, registry generation). tools.registry exposes a monotonic
_generation counter bumped on every register/deregister/alias/MCP
refresh (its docstring explicitly invites generation-keyed memoisation),
so a cache entry is valid until the registry changes. External callers
never pass visited, so the memo engages exactly at the public entry
and the internal cycle-detection recursion is untouched.
Measured: _get_platform_tools drops 165us -> 59us per call (3x) with the
xAI credential fix simulated; /tools completion ~2ms -> ~77us/keystroke
combined. Regression tests: repeat resolution is a memo hit (get_toolset
called once), a generation bump forces a fresh resolve, and the memoised
result is identical to a fresh resolution.

get_default_hermes_root() resolves HERMES_HOME against the platform
native home (~80us of path resolution) on EVERY call and is called at
31+ sites — every _load_global_auth_store() (per provider row in the
/model picker), kanban, backup, gateway, update. Its result depends
only on (HERMES_HOME, native home), so memoise it keyed on those two
inputs, compared for free on each call (freshness-correct even if a
test or plugin mutates HERMES_HOME mid-process).
_load_global_auth_store() re-read + re-parsed the global auth.json on
every call; read_credential_pool() -> load_pool() runs it once per
provider row in the /model picker even when the profile has entries and
the global fallback never fires. Memoise keyed on the global auth
file's path+mtime (same pattern as _nous_auth_status_cache); the store
only changes when a global-scope auth write touches the file.
Measured (profile mode, 30-provider global store): get_default_hermes_root
81us -> 10us; _load_global_auth_store 128us -> 66us; load_pool 165us ->
137us per call — ~2ms saved per /model picker render (20 provider rows).
Regression tests: hermes_constants memo pin (no path resolution on
repeat calls, HERMES_HOME change forces a fresh resolution); global-store
memo pins (store read once across repeats, mtime bump re-reads once,
absent store stays cheap).

The /tools and /personality completers run on every keystroke while the
user types those commands (complete_while_typing), and both re-read +
re-parse the full config on each keypress:
- _tools_completions called load_config() — the defensive deepcopy
(~340us/call on cache hit) even though it only reads toolset enable
state + MCP server names. Switched to load_config_readonly() (the
perf(agent) #74322 pattern; this per-keystroke site was missed).
- _personality_completions called load_cli_config() — a full YAML parse
+ deep merge of the built-in defaults (~110us) — on every keystroke.
Memoised keyed on the config file path+mtime (same pattern as load_env
/ _nous_auth_status_cache), so the parse runs once per config state.
Measured: /tools 357us -> 18us per keystroke; /personality parse drops
from 1-per-keystroke to 1-per-config-change (500 keystrokes -> 1 parse).
Regression tests: _tools_completions uses the readonly loader (deepcopy
loader never called); personality memo parses once across repeated
completions and re-parses once after a config mtime change.

The main.py decomposition re-exported the sessions/update/dashboard command
surface with eager from-imports, so every hermes invocation (including
hermes --version) paid for update_cmd's dependency chain (jwt, click,
cryptography). Resolve the re-exports through the existing PEP 562 module
__getattr__ (same pattern as _PROVIDER_MODELS) so each module loads on
first actual use. Internal call sites go through a _self() helper because
bare-name lookups do not trigger __getattr__; _self() imports sys locally
since update tests patch hermes_cli.main.sys. The
_warn_stale_dashboard_processes back-compat alias moves into the lazy
surface, and the sessions argparse dispatch defers sessions_cmd to call
time. Monkeypatching hermes_cli.main.<name> keeps working: a patch sets a
real module attribute, which shadows __getattr__.
Measured (Windows 11, Python 3.11, median of 7 warm runs):
import hermes_cli.main 253ms -> 196ms (-22%).

Read the durable display transcript when creating a branch instead of copying the compacted model projection. Hydrate the Desktop branch boundary from persisted history, avoid stale whole-chat counts, and seed the new tile from the backend snapshot. Add regression coverage for compacted histories, visible-message counts, selected prefixes, and hydration races.
