Two-part fix for the dashboard fd exhaustion reported in #81547:
1. Raise RLIMIT_NOFILE soft limit on startup (before uvicorn binds).
macOS defaults to 256 for LaunchAgent processes — too tight for the
dashboard which opens 3 fds (db+wal+shm) per SessionDB per request
across all profiles. After days of polling the soft limit exhausts
and every os.listdir/open raises OSError [Errno 24]. The helper raises
to the hard limit (or minimum 4096), matching the reporter's ulimit
workaround. No-op on Windows (no resource module).
2. Replace bare Path.iterdir() with context-managed os.scandir() in four
dashboard hot paths: _fallback_profile_dicts, file manager list,
checkpoint listing, and plugin discovery. iterdir() returns a
generator that holds an open directory fd until fully consumed; if
an exception interrupts iteration the fd leaks. os.scandir() is an
explicit context manager that guarantees close on exit, following
the same idiom already used in /api/fs/list.
Tests: 6 passed, 3 skipped (resource-module tests skip on Windows).
Follow-ups on the salvaged Browser Use CLI integration (PR #66476):
- browser_exec runs model-written Python on the host. Strip it at
tool-definition time for sessions whose resolved toolsets exclude
'terminal' so terminal-less surfaces (locked-down messaging configs)
don't silently regain host code execution through the browser toolset.
Session-level gate in model_tools, not a check_fn (check_fn results are
TTL-cached process-wide across sessions).
- Replace the live 'browser-use skill' schema fetch with a pinned helpers
digest: no third-party version-drifting text in the prompt, byte-stable
schema across machines. A/B benchmarked (108 runs, opus-4.8 + kimi-k3,
6 multi-step web tasks x 3 arms x 3 reps): pinned digest matches the
full skill dump 36/36 vs 36/36 at ~equal tokens; both cut total task
tokens ~60% vs the legacy browser_* toolset.
- Docs note for the terminal gate; contributor mapping for salvage.
Two hardening guards extracted from #82766 by @StanleyStetson:
- bool is an int subclass, so a JSON `true` in truncate_before_user_ordinal
coerced via int() to ordinal 1 and aimed a CONFIRMED rewind at the second
user turn — the same silent-loss class as #82756. Reject with 4004.
- confirm_truncate with no truncation target is leaked client rewind state
on an ordinary submit; fail fast with 4004 instead of silently ignoring
the flag, so the corrupted client state is surfaced.
Part of the composite fix for #82756.
`truncate_before_user_ordinal` is an index into the list of *real* user
turns. The gateway builds that list with `role == "user" and not
display_kind`, and `test_prompt_submit_truncate_ordinal_skips_display_kind_rows`
already pins why: "Without the filter, a trailing marker shifts the ordinal
so the wrong message is targeted for truncation."
`_apply_personality_to_session` broke that invariant at the producer. Its
pivot marker rides as `role=user` — deliberately, so strict
OpenAI-compatible providers accept it mid-conversation (the same reason
`_append_model_switch_marker` does) — but unlike the model-switch marker it
carried no `display_kind`. The gateway therefore counted it as a real user
turn while no client ever renders it as one.
After a personality change the two sides address different lists: every
later rewind/edit/regenerate resolves one slot too early, and
`replace_messages()` hard-DELETEs the extra span. That is the reported
signature — an in-range, valid ordinal, `confirm_truncate: true`, and a cut
that moved backwards with no user rewind action.
Tag the pivot like the model-switch marker, and teach the desktop to
project the kind as a timeline row so a persisted marker is never rendered
— or counted — as a user turn on the client side either. Both ends must
exclude it; excluding it on only one end just inverts the drift.
The regression test drives the real injection point rather than a
hand-written marker dict. Without the fix it fails with "the pivot shifted
the ordinal: the cut landed at 3 instead of 5", losing a turn the user
never asked to drop.

_model_sort_key treated YYYYMMDD snapshot stamps (e.g.
claude-opus-4-20250514) as version components, so 20250514 > 8
and resolve_alias("opus", "anthropic") returned the wrong model.
Fix: split components ≥ 19_000_101 (smallest plausible date stamp)
out of the version tuple, keeping them as a trailing tiebreaker so
bare IDs sort before their dated snapshots and newer snapshots
before older ones. Shorter numeric components (mistral-large-2411,
gpt-4-0613) keep their current behavior. No models.dev dependency
in the sort path.
Complements the cherry-picked contributor fixes and closes out the
remaining sites of the 'missing explicit encoding' bug class, which is
now permanently gated by ruff PLW1514 (enabled repo-wide in
pyproject.toml and enforced by the blocking `ruff check .` step in
.github/workflows/lint.yml):
- tools/memory_tool.py: read MEMORY.md/USER.md via utf-8-sig so a
Notepad BOM never glues U+FEFF onto the first entry (issue #10878,
PR #10888 by @easyvibecoding — strict-decode contract of
_read_raw_checked preserved rather than errors="replace", so
undecodable files still refuse read-modify-write instead of being
lossily rewritten). Regression tests included.
- tools/skills_tool.py: SKILL.md and skill file reads pinned to
utf-8-sig + errors="replace" — deterministic across platforms instead
of the locale fallback proposed in PR #51701 (superseded: falling back
to cp1252/GBK makes the same skill render differently per host); .env
reader aligned with the canonical utf-8-sig dialect in hermes_cli/config.py.
- agent/shell_hooks.py, hermes_cli/main.py, gateway/slash_commands.py:
explicit utf-8 on the remaining fdopen/open text-mode sites flagged by
the AlexFucuson9 sweep series (#56033#56940#65565#66782#66791).

Own the surrogate-crash class at three chokepoints instead of leaf sites:
- finalize_turn scrubs final_response once where model text leaves the
conversation loop — covers oneshot stdout (#80366), NIM/any-provider
responses (#19819), and every delivery consumer of the turn result.
- _sanitize_gateway_final_response scrubs at the gateway chat-surface
boundary — Telegram utf16_len (#55309) and Signal formatting (#55143)
can no longer see a lone surrogate; raw-text surfaces keep passthrough.
- run_conversation walks the fully-built api_kwargs with
_sanitize_structure_surrogates so tool descriptions (session_search,
#50959) and every other request-body leaf are JSON-encodable before
any provider sees them.
Regression tests pin all three chokepoints plus helper semantics.
Cherry-picked alongside #79240 (TheophilusChinomona) and #80374
(rainbowgore) whose commits precede this one with authorship preserved.
The salvaged fix covered run_workflow.py and hardware_check.py. The same
locale-default read of user-authored workflow JSON exists in five sibling
scripts (auto_fix_deps, check_deps, extract_schema, health_check,
run_batch) — same bug class, same utf-8-sig fix. Invariant test extended
to pin all nine read sites.
The pdf half of the original PR is superseded: those scripts were
replaced wholesale by the clean-room rewrite (#81890), which ships
UTF-8-explicit I/O enforced by its own invariant test.
Follow-up on the cherry-picked contribution from @michaelsam94 (#51794):
replace display-string/exact-value snapshot assertions with invariant
checks per the no-change-detector-tests policy. Live-tested
fal-ai/nano-banana-2 and fal-ai/nano-banana-2/edit through the real
payload builders: both pass.
- Add contributors/emails/Axmr1@users.noreply.github.com for CI
attribution check (bare noreply format needs explicit mapping)
- Update opencode-zen plugin docstring: Go routing now includes
GPT → codex_responses and Qwen → anthropic_messages (was stale,
only listed MiniMax and GLM/Kimi)
Replace the 'describe everything in thorough detail' auto image-preprocess
prompt with a concise 2-4 sentence summary prompt so image-bearing gateway
messages stop generating ~2000-char descriptions (35s+ on local models).
Prompt-only variant of #10852: the max_tokens=500 cap and the
preserve_max_tokens aux-client plumbing from the original PR are
intentionally dropped to stay compatible with the max-tokens-knob policy
direction (#75253 removes hardcoded vision caps).
Fixes#10809
- Fix _usage_audit_path() to use _get_hermes_home() instead of hardcoded
Path.home() / '.hermes' (profile-safe resolution, sweeper finding)
- Rewrite skip_background_review tests to exercise finalize_turn() directly
instead of duplicating the guard expression (sweeper finding)
- Fix response_silent audit field to use _is_cron_silence_response()
instead of the buggy SILENT_MARKER substring check it was meant to
replace (simplify-code review finding)
- Remove dead 'model' in locals() guard — model is always in scope
before the try block (simplify-code review finding)
- Extract _stub_agent_for_finalize() helper to eliminate ~40 lines of
copy-pasted agent stubbing in tests (simplify-code review finding)
- Clean up 'Phase 0.5' instrumentation comments
Bare-noreply author email (no NNN+ prefix) on the PR #80376 salvage is not

* fix(discord): reject empty outbound messages
* test(discord): cover empty final reply backfill state
Missed-message backfill decides what to replay from discord_messages, so
a dropped final reply must be recorded as failed by the new guard the
same way the exception path records one — otherwise the reply is both
never sent and never retried.

* fix(agent): adopt .env credential/base-url edits at the turn boundary
A Settings save (desktop PUT /api/env, hermes setup) updates .env and
the saving process's os.environ, but a live session worker keeps the
base_url/api_key captured at agent init until restart — an open chat
silently kept calling the old endpoint (e.g. a local-server key sent to
api.openai.com, failing with an opaque 401).
Add AIAgent._try_refresh_env_client_credentials(), called at the start
of each conversation turn: re-resolve the provider's env-sourced
credentials (load_env() is mtime-memoized, so an unchanged file costs
one stat()) and rebuild the client via the existing
_replace_primary_openai_client machinery when the user edited them.
The refresh reacts only to env edits — resolved values changed since
the last look — never to mere divergence from the agent's current
values: credential-pool rotation and failover legitimately move the
session off the env credential, and stomping those back would flap.
Config model.base_url / pool custom endpoints keep precedence: edits
are only adopted while the session still runs on the registry default
or the previously-seen env value.
Lift _get_env_prefer_dotenv out of _seed_from_env to module level
(get_env_prefer_dotenv) so both the pool seeder and the per-turn
refresh share the same .env-over-os.environ resolution, including the
op:// indirection handling.
Fixes#67821

* fix(agent): address sweeper review on env credential refresh
- Cover named custom providers (#67935): provider="custom" has no
PROVIDER_REGISTRY entry, so resolve the config block's key_env through
the same lookup the runtime resolver uses.
- Make the edit baseline transactional: a failed client rebuild rolls the
agent back and leaves _env_creds_seen un-advanced so the unchanged edit
is retried next turn.
- Recompute route-derived TLS material and default headers on a base-url
change, via a _reapply_route_client_config helper shared with
credential-pool rotation so the two paths cannot drift.
- Rebase onto main: get_env_prefer_dotenv keeps the scoped _get_secret
semantics from the profile-isolation fix (no raw os.environ reads).
