f512d6f020 feat(plugins): pre_tool_call approve action escalates to human gate
Extend the pre_tool_call plugin hook return contract with a new directive:

    {"action": "approve", "message": "why this needs human confirmation"}

Previously a pre_tool_call hook could only veto a tool call (action: block)
or allow it silently. It could not escalate to the existing human-approval
flow. This unlocks user-defined runtime approval rules on ANY tool (HTTP
writes, file writes to sensitive paths, email sends), enforced at runtime —
resolving #51221 as a pure plugin, with no core approval.py rule schema.

Mechanism:
- get_pre_tool_call_directive() returns (action, message) for block|approve;
  get_pre_tool_call_block_message() kept as a block-only back-compat shim.
- resolve_pre_tool_block() is the single dispatch-site chokepoint: fetches
  the directive and, for approve, invokes the human gate; fail-closed to a
  block on denial, timeout, or gate exception. ALL FOUR tool-dispatch sites
  now call it: tool_executor (concurrent + sequential), agent_runtime_helpers,
  and model_tools.handle_function_call.
- request_tool_approval() escalates via the SAME machinery as Tier-2
  dangerous commands: session/permanent allowlist, prompt_dangerous_approval
  (CLI) / submit_pending (gateway), [o]nce/[s]ession/[a]lways/[d]eny,
  timeout fail-closed, approvals.cron_mode for cron contexts.

Architecture: extracted the shared decision core into _run_approval_gate(),
called by BOTH check_dangerous_command() and request_tool_approval() so the
fail-closed / cron / gateway / yolo / persist policy lives in ONE place and
cannot drift. Fixed a latent divergence — the plugin path now honors --yolo.

Approval grain: [a]lways is keyed on tool_name + a hash of the reason (an
explicit plugin rule_key overrides), so distinct reasons on the same tool
persist independently instead of one 'always' blanketing the whole tool.

Non-interactive: cron honors approvals.cron_mode (parity with commands); any
other non-interactive non-gateway context fails CLOSED for the plugin path
(the command path keeps its historical fail-open default, unchanged).

No new config schema, no new env vars, no new hook events.

fix(cli): reliable interrupts, bounded exit, and exit feedback (#57000)
Three CLI reliability fixes:

1. Interrupt reliability: chat() only re-queued the user's interrupt
   message when the turn result carried interrupted=True. When the agent
   thread raced past its last interrupt check (or finished) before the
   interrupt landed, the message was silently dropped — and the stale
   _interrupt_requested flag left on the agent instantly aborted the
   NEXT turn. Un-acknowledged interrupt messages are now re-queued as
   the next turn and the stale flag is cleared (only when the agent
   thread actually exited). The clarify-race path also parks the message
   in _pending_input instead of dropping it.

2. Slow exit (5+ min): stdlib ThreadPoolExecutor workers are non-daemon
   and joined unconditionally by concurrent.futures' atexit hook — even
   after shutdown(wait=False). One wedged tool worker (abandoned after
   interrupt/timeout) held the process open forever. Promoted
   async_delegation's daemon executor to a shared tools/daemon_pool
   module and adopted it in tool_executor (concurrent tool batches),
   memory_manager (background sync), delegate_tool (child timeout wrapper
   + batch fan-out), and skills_hub (source fan-out). Added a 30s exit
   watchdog (HERMES_EXIT_WATCHDOG_S) armed at _run_cleanup start as a
   backstop for wedged cleanup steps.

3. Exit jank: after prompt_toolkit tears down the input/status bars the
   terminal sat silent for the whole cleanup window, looking hung. Print
   'Shutting down… (finalizing session)' immediately at exit start.

E2E: live PTY interrupt of a foreground 'sleep 120' terminal tool now
aborts in ~1s and the typed message runs as the next turn; wedged-worker
+ wedged-cleanup subprocess exits in 5.8s (watchdog) instead of hanging.

The persist user-message override was applied in place to the live messages
list. On the early crash-resilience persist (which runs BEFORE api_messages is
built), that stripped observed group-chat context off the live user message and
silently dropped it when observe_unmentioned_group_messages was enabled.

Fix at the single chokepoint: _flush_messages_to_session_db resolves the
override (idx/content/timestamp) locally and applies it ONLY to the row written
to the DB — the live dict is never mutated, so EVERY persist caller (early
persist, mid tool-loop flush, /resume, /branch) is protected uniformly. This
supersedes the earlier shallow-copy approach, which broke the intrinsic
_DB_PERSISTED_MARKER idempotency (copies never propagated the marker back to
the live dicts → duplicate rows) and closes the sibling class tracked in #56303.

Trailing empty-response scaffolding is still dropped from the live list in
_persist_session (unchanged behavior).

Salvaged from #48817; chokepoint reworked to coexist with the marker-based
dedup (#50372).

22a137ed40 fix(agent): prefer late-completing real result over timeout message (review)
Review follow-up on the concurrent-tool deadline salvage. timed_out_indices is
snapshotted from not_done at the deadline; a worker can still finish and write
results[i] in the window before the post-execution result loop reads it. The
loop unconditionally replaced results[i] with a fabricated 'timed out' message
for any snapshotted index, discarding a genuinely-successful (just-late) result.

Gate the timeout message on 'and r is None' so a real result always wins. Add a
regression test that forces the snapshot-vs-result-loop race deterministically
(mutation-checked: reverting the guard fails it). Also document the intentional
detached-worker leak at the executor abandon site.

c1784e9093 fix(agent): bound concurrent tool execution with a wall-clock deadline
A tool with no internal interrupt check (read_file, web_search, or a wedged
terminal backend) that never returns keeps the concurrent-tool poll loop alive
forever: the loop only breaks when all futures finish or an interrupt is
requested, and the 30s heartbeat resets the gateway idle monitor so idle-kill
never fires. The ThreadPoolExecutor was also used as a context manager, so its
__exit__ joined the hung worker with wait=True.

Add a wall-clock batch deadline (HERMES_CONCURRENT_TOOL_TIMEOUT_S, default 420s
— above the 360s web_extract timeout; 0/negative disables). When it fires:
cancel pending futures, signal an interrupt to the worker threads, abandon the
executor (shutdown wait=False, cancel_futures=True) so hung threads aren't
joined, and return a per-tool 'timed out' result for the unfinished calls while
still surfacing the finished ones. Also fixes the latent futures.index(f)
lookup (ambiguous with duplicate futures) by tracking a future->index map.

Salvaged from #54562.

053424c486 fix(agent): preserve final_response on failure returns
AIAgent.run_conversation() promises a dict with final_response, but 16
terminal-failure branches returned dicts that either omitted the key or
set it to None. Callers that index result['final_response'] directly
(run_agent.py chat() + the __main__ printer) turn a real provider/context
failure into an opaque KeyError instead of surfacing the actionable error.

Every offending branch already carried usable 'error' text, so this
mirrors that text into final_response for all 16 sites (8 that omitted the
key, 8 that returned None). Adds an AST regression test that fails if any
run_conversation() dict return omits final_response or sets it to a literal
None, and tightens the invalid-response test to assert final_response == error.

bc6cd46925 fix(agent): restrict todo hydration to paired assistant todo calls
The gateway/API server rebuilds the in-memory TodoStore by replaying
caller-supplied conversation_history. _hydrate_todo_store previously
accepted any role:tool message containing a "todos" array, so a forged
bare tool result could seed arbitrary todo state and re-inflate context
every turn (GHSA-5g4g-6jrg-mw3g).

Restrict hydration to tool results paired with an earlier assistant
todo tool call (matching tool_call_id, function name == todo, no
user/system boundary between). Reuse the existing _get_tool_call_id/
name_static helpers so dict- and object-shaped tool calls both work.
Add a generous MAX_TODO_RESULT_CHARS payload guard to drop absurd
forged results before parsing; item/content caps already exist on main.

fix(agent): repair empty-name tool_calls in sanitizer to prevent Responses 400 (salvage #12807/#52893) (#55922)
* fix(agent): drop tool_calls with empty function.name to prevent orphan 400

Salvage of #12807 by @melonboy312 — rebased onto current main (sanitizer
moved to agent_runtime_helpers), scoped to the sanitizer fix, with a
regression test that fails without it.

* fix(agent): repair (not drop) empty-name tool_calls to preserve anti-priming + prevent 400

Dropping empty-name tool_calls in the pre-call sanitizer collided with #47967,
which intentionally keeps an empty-name call paired with a synthesized
'tool name was empty' anti-priming result so weak models self-correct without
a full catalog dump. Dropping the call orphaned that result and stripped the
signal (breaking tests/agent/test_empty_tool_name_loop_dampening.py).

The actual HTTP 400 cause is an ORPHANED function_call_output (adapter drops
the empty-name function_call but keeps its output). Rename the blank name to a
non-empty sentinel instead: the call and its result stay paired, the adapter
no longer drops the function_call, no orphan, no 400 — and the anti-priming
result content the model needs is preserved.

fb07215844 fix(copilot): recognize enterprise subdomains in host checks
The earlier enterprise base URL change (proxy-ep parsing) gave us URLs
like `api.enterprise.githubcopilot.com`, but ~15 host-matching call
sites still hard-coded `api.githubcopilot.com`. Enterprise users would
therefore drop the `Copilot-Integration-Id: vscode-chat` header at
client-build time, and upstream rejected requests with:

    The requested model is not available for integrator "zed"
    (or "copilot-language-server") — verify the correct
    Copilot-Integration-Id header is being sent.

The header was correct in copilot_default_headers(); it just never
made it into default_headers for non-default hostnames because every
detector compared against the exact string "api.githubcopilot.com".

This commit broadens all those checks to "githubcopilot.com" via
base_url_host_matches (which already does proper subdomain matching),
so api.enterprise.githubcopilot.com, api.business.githubcopilot.com,
etc. all share the same headers, vision routing, max_completion_tokens
selection, and reasoning-effort detection as the default endpoint.

Also adds ".githubcopilot.com" to _URL_TO_PROVIDER so context-window
resolution via models.dev works for enterprise base URLs, and tightens
_is_github_copilot_url to use suffix matching instead of strict equality.

Tests:
- New: enterprise Copilot endpoint preserves Copilot-Integration-Id
- New: enterprise endpoint returns max_completion_tokens (not max_tokens)
- Existing 333 base_url / copilot / aux-client / credential-pool tests pass

ea1372d2af fix(security): wire session-id sanitizer into artifact paths + API boundary
Defense-in-depth on top of _safe_session_filename_component (#5958):

Sink (makes the bad write impossible regardless of entry point):
- run_agent._save_session_log: sanitize session_id before building the
  session_{sid}.json snapshot path.
- agent_runtime_helpers.dump_api_request_debug: sanitize before building
  the request_dump_{sid}_{ts}.json path.

Boundary (clean 400 instead of a silently-hashed filename):
- api_server rejects path-traversal-shaped X-Hermes-Session-Id on the
  session-continuation path and the explicit /api/sessions create path,
  reusing gateway.session._is_path_unsafe (mirrors the native gateway's
  entry-boundary guard). Also enforces the session-header length cap on
  the continuation path.

Tests: traversal session_id stays contained at the write site; sanitizer
always yields a traversal-free segment; the API header rejects
../, absolute, and Windows-traversal IDs with 400.

1ab35ba25d fix(anthropic): stop SDK auto-retry double-firing and raise Retry-After cap to 600s
The Anthropic SDK clients were built without max_retries, so the SDK
default (max_retries=2) retried 429/5xx with its own backoff that ignores
Retry-After — double-retrying inside hermes's outer loop and burning
request slots against a bucket that won't refill for minutes. Set
max_retries=0 on all Anthropic/AnthropicBedrock client constructions so
the outer conversation loop (which already honors Retry-After) owns retry.

Also raise the Retry-After cap in the conversation loop from 120s to 600s.
Anthropic Tier 1 input-token buckets reset in ~171s, so the 120s cap made
hermes retry before the reset window and re-trip the limit.

32732a8f83 fix(agent): cap same-entry credential refreshes so fallback can activate (#26080)
A persistent upstream 401 on a single-entry OAuth pool (common for Claude
Max subscribers) made the credential-pool recovery spin forever:
try_refresh_current() re-mints a fresh token and reports success on every
401, so recover_with_credential_pool returned True and the retry loop
continue'd without ever incrementing retry_count or reaching the
auth-failover block. The configured fallback_model never activated and the
agent appeared to hang.

Cap consecutive successful same-entry refreshes (keyed by provider +
pool-entry id) at 2; once exceeded, treat the credential as unrecoverable
and return not-recovered so the loop falls through to
_try_activate_fallback. The 429/billing paths already rotate-or-fall-through
correctly (mark_exhausted_and_rotate returns None on a single entry), so
only the auth-refresh branch needed the cap.

f062cf076b fix(agent): also treat provider=ollama as an Ollama GLM backend
Follow-up to the #13971 fix: a genuine native Ollama provider reached
through a reverse proxy carries no ollama/:11434 URL signature, so the
restricted detection would miss it. Add provider=="ollama" as an
explicit True case (idea from #14789, @Tranquil-Flow) and cover both it
and the #13971 LiteLLM-proxy-to-zai false-positive with E2E tests.

00a8252b7d fix(agent): scope Ollama/GLM stop-to-length heuristic to Ollama only
The _is_ollama_glm_backend() function was too broad: any local endpoint
running a GLM model was treated as Ollama, triggering the stop->length
misreport heuristic introduced in 8011aa3. This caused false truncation
detection on sglang, vLLM, LM Studio, and other non-Ollama servers that
correctly report finish_reason.

When a GLM model on sglang/vLLM returned finish_reason='stop', the agent
mistakenly reclassified it as 'length' if the response didn't end with
a whitelisted punctuation character (ASCII or CJK). This particularly
affected Chinese-language responses and Markdown-formatted text.

Root cause: the is_local_endpoint() fallback assumed any local GLM
endpoint = Ollama. But many non-Ollama servers also run on localhost.

Fix: remove the is_local_endpoint() catch-all. Only detect Ollama via
its distinctive signatures (port 11434, 'ollama' in URL). All other
local servers are assumed to report finish_reason correctly.

This is the correct tradeoff because:
- False negatives (Ollama at custom port, heuristic not triggered) only
  mean the user sees a truncated response — same as having no heuristic
- False positives (non-Ollama server, heuristic wrongly triggered) inject
  spurious continuation messages into the conversation — strictly worse

Adds two tests:
- sglang GLM response is NOT reclassified as truncated
- Ollama GLM on port 11434 still triggers the heuristic as before

8233598e64 fix(interrupt): keep partial streamed reply when stopped mid-response
Stopping a turn while the model is streaming (stop/esc to redirect) raised
InterruptedError, set final_response to the throwaway "waiting for model
response" sentinel, and persisted messages WITHOUT the assistant text that
was already streamed to the screen. The next turn then had no record of the
half-finished reply, so the model appeared to "forget" what it just said.

Recover the on-screen text from _current_streamed_assistant_text in the
InterruptedError branch and append it as the assistant turn (and surface it
as final_response). The metadata sentinel is kept only when nothing was
streamed yet, preserving the ACP/client suppression behavior.

Completes the partial-stream recovery from 397eae5d9 (which wired the same
_current_streamed_assistant_text salvage into the connection-failure twin
but missed the user-interrupt path). The lossy handler dates to c98ee9852.

b1b20270c4 refactor(memory): move write-mirror gating behind MemoryManager interface
The success/staged gating and op-expansion for mirroring built-in memory
writes to external providers lived in a standalone agent/memory_write_bridge.py
helper called inline from two core call sites (tool_executor.py,
agent_runtime_helpers.py). That left the mirror decision-making in the agent
loop, outside the memory-provider interface.

Fold it into a new MemoryManager.notify_memory_tool_write() entry point: the
loop now hands over the raw tool result + args and a metadata callback, and the
manager decides whether/what to mirror. Both core call sites collapse to a
single call; the orphan module is removed. No MemoryProvider ABC change.

Tests rewritten as behavior tests against the manager method.

fix(agent): strip stale reasoning_content when falling back to a strict provider (#50480)
* fix(agent): strip stale reasoning_content when falling back to a strict provider

A reasoning primary (DeepSeek/Kimi/MiMo thinking mode) pins reasoning_content
on every assistant tool-call turn (a single space " " pad). api_messages is
built once under the primary; on a mid-session fallback to a strict
OpenAI-compatible provider (Mistral, Cerebras, Groq, SambaNova), those stale
pads were replayed verbatim and rejected with HTTP 400/422:

    body.messages.2.assistant.reasoning_content: Extra inputs are not
    permitted  (input: ' ')

reapply_reasoning_echo_for_provider() only ever ADDED pads, so it never
reconciled history built under a reasoning primary against a strict fallback.
copy_reasoning_content_for_api() also leaked empty-string and 'reasoning'-only
shapes to non-pad providers.

Fix both sites: when the active provider does not enforce echo-back, strip
reasoning_content (empty, space-pad, or non-empty) entirely. Re-padding when
switching TO a reasoning provider is preserved. Covers the Cerebras 400 from
#45655 and the DeepSeek->Mistral 422 fallback report.

Refs #45655.

* test: update reasoning-replay tests for strict-provider stripping

test_explicit_reasoning_content_beats_normalized_reasoning_on_replay was
implicitly running on the OpenRouter fixture (non-pad); pin it to a reasoning
provider so the precedence it checks is observable. Add a positive
strict-provider test asserting reasoning_content is stripped on replay.

bb46bf8ce4 fix(agent): surface model refusals instead of retrying them as errors
A Claude refusal (HTTP 200, stop_reason="refusal", empty content) was
laundered into a generic retry loop and surfaced as a misleading
"rate limited / invalid response" or "no content after retries" error,
burning paid attempts reproducing a deterministic refusal.

This hit two distinct paths:

- Direct Anthropic (anthropic_messages): validate_response rejected the
  empty-content refusal *before* normalize_response mapped refusal ->
  content_filter, so it fell into the invalid-response retry loop.
- Nous Portal / OpenAI-compatible (chat_completions): the portal surfaces
  a Claude refusal via message.refusal with empty content, which sailed
  past validation and died in the empty-response retry loop.

Fix (one unified content_filter dispatch for all backends):
- AnthropicTransport.validate_response: accept empty content when
  stop_reason == "refusal" so it flows to normalize_response.
- ChatCompletionsTransport.normalize_response: promote message.refusal to
  content + a content_filter finish reason.
- conversation_loop: handle finish_reason == "content_filter" - fire the
  api_request_error hook (content_policy_blocked), try a configured
  fallback once, else return a clear terminal refusal message. Never retry
  a deterministic refusal.

Supersedes #43084, which fixed only the direct-Anthropic path and could
not reach the chat_completions/portal path.

Tests: transport-level (validate_response refusal, message.refusal
promotion) + end-to-end loop (refusal surfaced, exactly one API call).

19c07c4037 fix(params): send max_completion_tokens for newer OpenAI families on custom endpoints
Third-party OpenAI-compatible endpoints (self-hosted gateways, OpenRouter,
Azure proxies) fronting gpt-4o / gpt-4.1 / gpt-5+ / o1-o4 models silently
received max_tokens and 400'd with unsupported_parameter, because the three
kwarg-selection sites only checked base_url_hostname(...) == "api.openai.com"
and fell through to max_tokens on every other host. The constraint is
enforced server-side by the model family, not by the URL, so name-based
detection is required as a fallback.

Changes:
- utils.py: new shared helper model_forces_max_completion_tokens(model) that
  prefix-matches gpt-4o, gpt-4.1, gpt-5, o1, o3, o4 families on normalized
  (lowercased, vendor-prefix-stripped) names.
- run_agent.py: _max_tokens_param ORs the helper into the URL check.
- agent/auxiliary_client.py:
  - auxiliary_max_tokens_param gains an optional keyword-only model arg.
  - _build_call_kwargs inline branch applies the same check for both
    provider == "custom" and non-custom paths.

Tests:
- tests/test_model_forces_max_completion_tokens.py: 31 new cases covering
  positive families, negatives (classic gpt-4, claude, llama, mistral, qwen,
  deepseek), vendor prefixes, case-insensitivity, whitespace, None/empty,
  and substring-not-prefix guards.
- tests/run_agent/test_run_agent.py::TestMaxTokensParam: 5 new model-based
  cases (custom + gpt-5.4, openrouter + gpt-4o-mini, custom + o1-preview,
  classic gpt-4-turbo keeps max_tokens, llama3 keeps max_tokens).
- tests/agent/test_auxiliary_client.py::TestAuxiliaryMaxTokensParam: new
  class, 7 tests covering the URL x model matrix.

test(run_agent): fix racy ordering in test_concurrent_handles_tool_error (#42356)
The test keyed the 'which call raises' decision on a shared invocation
counter (first call → raise, second → success), then asserted the error
landed in messages[0] (c1) and success in messages[1] (c2). But
_execute_tool_calls_concurrent runs the two web_search calls on a thread
pool with no ordering guarantee — c2's handler can be invoked first, take
the 'first call raises' branch, and the error ends up in messages[1].
Results are ordered by tool_call_id, so messages[0] (c1) was then 'success'
and the assertion failed.

It passed in isolation but reliably failed under CI's full parallel slice
(8 xdist workers) where the scheduler actually interleaves the two handlers.

Fix: tie the raise to a specific tool call via its arguments (q=boom raises,
q=ok succeeds) instead of invocation order, and assert tool_call_id ↔ content
pairing explicitly. Deterministic regardless of thread scheduling — verified
10/10 in isolation and the full TestConcurrentToolExecution class (32) green.

fix(stream): don't report dropped mid-tool-call streams as output truncation (#42314)
* fix(stream): don't report dropped mid-tool-call streams as output truncation

A streaming tool call whose SSE ends with no finish_reason (the upstream
delivers the tool name + opening '{' then closes the connection cleanly,
no terminator, no [DONE]) was stamped finish_reason='length' by the mock
builder. That routed it through the output-cap truncation path: 3 useless
max_tokens-boosted retries, then the misleading 'Response truncated due to
output length limit' error — even though the model never reported hitting
any cap.

Reproduced live on nvidia/nemotron-3-ultra:free via the Nous dedicated
endpoint, which stalls/drops during large tool-arg generation (50s-4m41s).

Now: when tool args are incomplete AND the provider sent no finish_reason,
tag the response as a partial-stream stub so the loop reports an honest
mid-tool-call drop and asks the model to chunk its output (existing
continuation machinery), instead of escalating output budget and lying.
A provider-reported finish_reason='length' still takes the real-truncation
path unchanged.

* test(stream): update truncated-tool-args test for drop-vs-cap split

test_truncated_tool_call_args_upgrade_finish_reason_to_length pinned the
old behaviour where ANY incomplete tool args → finish_reason='length' with
tool_calls preserved. That single-chunk-no-finish_reason scenario is exactly
the mid-tool-call stream drop now reclassified as a partial-stream stub.

Split into two tests matching the new contract:
- no finish_reason + incomplete args → PARTIAL_STREAM_STUB_ID, tool_calls=None,
  _dropped_tool_names set (the drop path)
- explicit finish_reason='length' + incomplete args → tool_calls preserved,
  'length' upgrade unchanged (the genuine output-cap path)

54870847cb refactor(agent): extract run_conversation prologue into agent/turn_context.py
Phase 1 of the god-file decomposition plan. run_conversation's ~470-line
once-per-turn setup block (stdio guarding, retry-counter resets, user-message
sanitization, todo/nudge hydration, system-prompt restore-or-build,
crash-resilience persistence, preflight compression, the pre_llm_call hook, and
external-memory prefetch) is moved verbatim into build_turn_context(), which
returns a TurnContext dataclass the loop unpacks.

Behavior-neutral move-and-name refactor: the builder mutates `agent` exactly as
the inline code did; only the locals the loop reads back are returned.

- run_conversation: 4602 -> 4217 LOC (-385)
- agent/conversation_loop.py: 4965 -> ~4580 LOC
- new agent/turn_context.py: focused, dependency-injected, unit-tested in isolation

Tests: tests/run_agent/ 1570 passed / 0 failed under per-file process isolation.
Relocation follow-ups: 413_compression mocks now patch both module references;
nudge/on_turn_start source-inspection guards point at the extracted module.

test(kimi): align stale parity/profile tests with thinking-xor-effort contract (#41095)
* test(kimi): align stale parity/profile tests with thinking-xor-effort contract

ce4e74b3 (fix(kimi): send thinking xor reasoning_effort, never both)
changed the Kimi profile to emit at most one of extra_body.thinking or a
top-level reasoning_effort, and added tests/plugins/model_providers/test_kimi_profile.py
to pin it — but left two older test files still asserting the removed
'send both' behavior, turning main red for every PR branched after it.

Update the stale assertions to the xor contract:
- explicit recognized effort (low|medium|high) -> reasoning_effort only,
  no thinking
- enabled w/o effort, or no reasoning_config -> thinking:enabled only,
  no reasoning_effort
- disabled -> thinking:disabled only

No production change.

* test(kimi): cover remaining xor stale assertions (profile_wiring, run_agent)

Two more test files asserted the pre-ce4e74b3 'thinking + reasoning_effort
together' behavior — landed in a different CI shard so they surfaced only
after the first batch went green:
- tests/providers/test_profile_wiring.py::TestKimiProfileParity (2)
- tests/run_agent/test_run_agent.py::TestBuildApiKwargs (3: kimi-coding,
  moonshot, moonshot-cn)

Same realignment to the xor contract: default/enabled-without-effort emits
thinking:enabled and no reasoning_effort; explicit effort emits
reasoning_effort only. Verified by running the full provider +
TestBuildApiKwargs Kimi surface (202 passed) plus a codebase-wide grep for
any remaining paired thinking+effort assertion (none).

40cea4d58d fix(agent): import SimpleNamespace for hook payload sanitization
_hook_jsonable() referenced SimpleNamespace without importing it, so
sanitizing any hook payload that contained one raised
NameError: name 'SimpleNamespace' is not defined.

Bedrock, Codex-responses, and the auxiliary client build their
response / message / tool_call objects as SimpleNamespace and hand the
raw objects to the post_api_request hook. The hook call sites swallow
exceptions (except Exception: pass), so the crash silently dropped the
observability hook for those providers.

Add the missing `from types import SimpleNamespace` and a regression
test covering the SimpleNamespace sanitization path.

fix(gemini): default native maxOutputTokens + strip OpenAI extra_body on Gemini endpoints (#39730)
* fix: respect disabled auto-compaction on context overflow

Port from anomalyco/opencode#30749.

When compression.enabled is false, NO automatic compaction trigger may
fire. The proactive token-threshold paths (preflight + post-response
should_compress gate) already honoured the setting, but the three
provider-overflow recovery paths in the agent loop — long-context-tier
429, 413 payload-too-large, and context-overflow — called
_compress_context() unconditionally, silently compressing and rotating
the session against the user's explicit choice.

Add a single guard at the top of the overflow-recovery dispatch: when
compression is disabled and the error is one of those three overflow
classes, surface a terminal error (compaction_disabled: True) telling the
user to /compress manually, /new, switch to a larger-context model, or
reduce attachments. Manual /compress (force=True) is unaffected — it never
enters this loop.

Tests: new TestOverflowWithCompactionDisabled (413 + 400 overflow don't
compress when disabled; control case still compresses when enabled).
Existing overflow-recovery tests updated to enable compaction explicitly
(they verify the recovery fires); fixture defaults flipped to True to
match production (compression.enabled defaults to True).

* fix(gemini): default native maxOutputTokens + strip OpenAI extra_body on Gemini endpoints

Two distinct failures hit users on the gemini provider with only Google
AI Studio keys set.

1. Truncation loop: build_gemini_request() only set maxOutputTokens when
   max_tokens was non-None. Hermes passes None to mean "unlimited", but
   Gemini's native generateContent does NOT treat an absent maxOutputTokens
   as full budget — it applies a low internal default and stops early with
   finishReason=MAX_TOKENS, truncating tool calls. The agent then retries
   3x and refuses the incomplete call. Now default to the published 65,535
   ceiling (shared by all current Gemini text models) when max_tokens=None.

2. HTTP 400 on Gemini endpoint: the chat_completions transport assembles
   profile extra_body (Nous portal 'tags', reasoning, provider prefs) and
   sends it via the OpenAI client to whatever base_url is resolved. When a
   profile that emits extra_body (e.g. Nous) is active but the endpoint is a
   native Gemini base_url — typical when only Google creds exist and a
   fallback/aux call lands on Gemini — Google rejects the unknown 'tags'
   field with a non-retryable 400. Strip all non-thinking_config extra_body
   keys when the resolved endpoint is native Gemini.

Verified E2E against real transport code: tags stripped on native Gemini,
preserved on Nous and the /openai compat endpoint; maxOutputTokens=65535
on None, explicit values respected.

827f251426 perf(observability): gate tool-hook emit on has_hook; slim per-tool footprint
The salvaged observer contract gated the API-request hot path on has_hook()
but left the per-tool emit ungated: every tool call ran result-field
derivation + payload dict build + invoke_hook dispatch even with zero
plugins registered.

- _emit_post_tool_call_hook now short-circuits on has_hook("post_tool_call")
  and derives status/error fields lazily (after the gate, only when a
  listener will consume them). status defaults to None -> derived; explicit
  blocked/cancelled callers still pass status through.
- transform_tool_result emit (pre-existing hook) likewise gated on
  has_hook(); skips _tool_result_observer_fields when no listener.
- Removed the now-redundant _tool_result_observer_fields pre-computation at
  the three ok-path call sites (model_tools, agent_runtime_helpers,
  tool_executor) — the helper derives them, so the no-listener path costs
  one dict lookup and the call sites shrink.
- Tests: stub has_hook=True where payload correctness is asserted; add a
  no-listener regression proving post_tool_call/transform_tool_result emit
  is skipped when nothing is registered.

0d9b7132ff feat(observability): observer-grade telemetry hooks + NeMo-Relay plugin
Adds backend-neutral observer hooks for plugins: session, turn, API
request, tool, approval, and subagent lifecycle events with stable
correlation IDs (session_id, task_id, turn_id, api_request_id,
tool_call_id, parent/child subagent ids). Extends VALID_HOOKS with
api_request_error and subagent_start.

Hot path is zero-cost when no plugin subscribes: has_hook()/presence
checks gate all payload construction, request payloads are returned
by reference when no middleware rewrites, and the sanitized response
payload no longer embeds raw response objects.

Bundles the optional NeMo-Relay observability plugin
(plugins/observability/nemo_relay) as an in-repo consumer of the new
hooks, peer to the existing langfuse plugin. Fails open when the
optional nemo-relay package is not installed.

fix(agent): stop reporting broken streams as output-length truncation (#36705)
A stream that drops mid-response after tokens are delivered (peer-closed
connection, stale-stream reconnect) is converted into a synthetic
finish_reason="length" stub. The conversation loop treated that network
stall as a max-output-tokens truncation: when the dropped content was a
tool call it retried exactly once, then hard-failed with "Response
truncated due to output length limit" — even on large-output models that
never hit any cap (e.g. Opus).

- Tool-call truncation now retries up to 3 times (was 1) with a
  progressive max_tokens boost, and is stub-aware: a PARTIAL_STREAM_STUB_ID
  stall prints "Stream interrupted mid tool-call — retrying (n/3)" instead
  of the false "model hit max output tokens", and the give-up message
  distinguishes a network drop from a real truncation.
- Length-continuation retries preserve the original request's output cap
  as a floor, so a high provider/model default isn't silently downshifted
  to 8K/12K on retry.
- Added _requested_output_cap_from_api_kwargs() helper.

Tests: stub-stall mid-tool-call recovery within 3 retries; continuation
preserves a large provider-default output cap.

Fixes #26425. Salvages the substance of #26427 (cap floor) and #9525
(retry bump), adapted to the post-refactor conversation_loop.py which
handles all three api_modes uniformly.
