92dcdbff66 fix: clarify interrupt re-queue label, document busy_input_mode behaviour
The '📨 Queued:' label was misleading — it looked like the message was
silently deferred when it was actually being sent immediately after the
interrupt. Changed to ' Sending after interrupt:' with multi-message
count when the user typed several messages during agent execution.

Added comment documenting that this code path only applies when
busy_input_mode == 'interrupt' (the default).

Based on PR #4821 by iRonin.

3f2180037c fix: also filter session_meta in /session switch restore path
The original PR missed the third CLI restore path — the /session switch
command that loads history via get_messages_as_conversation() without
stripping session_meta entries.

6bf5946bbe fix: filter transcript-only roles from chat-completions payload (#4715)
Add a provider-agnostic role allowlist guard to _sanitize_api_messages()
that drops messages with roles not accepted by the chat-completions API
(e.g. session_meta). This prevents CLI resume/session restore from
leaking transcript-only metadata into the outgoing messages payload.

Two layers of defense:

1. API-boundary guard: _sanitize_api_messages() now filters messages by
   role allowlist (system/user/assistant/tool/function/developer) before
   the existing orphaned tool-call repair logic. This protects all
   current and future call paths.

2. CLI restore defense-in-depth: Both session restore paths in cli.py
   now strip session_meta entries before loading history into
   conversation_history, matching the existing gateway behavior.

Closes #4715

de5aacddd2 fix: normalise \r\n and \r line endings in pasted text
Windows (CRLF) and old Mac (CR) line endings are normalised to LF
before the 5-line collapse threshold is checked in handle_paste.

Without this, markdown copied from Windows sources contains \r\n but
the line counter (pasted_text.count('\n')) still works — however
buf.insert_text() leaves bare \r characters in the buffer which some
terminals render by moving the cursor to the start of the line,
making multi-line pastes appear as a single overwritten line.

cc54818d26 fix(mcp): stability fix pack — reload timeout, shutdown cleanup, event loop handler, OAuth non-blocking (#4757)
Four fixes for MCP server stability issues reported by community member
(terminal lockup, zombie processes, escape sequence pollution, startup hang):

1. MCP reload timeout guard (cli.py): _check_config_mcp_changes now runs
   _reload_mcp in a separate daemon thread with a 30s hard timeout. Previously,
   a hung MCP server could block the process_loop thread indefinitely, freezing
   the entire TUI (user can type but nothing happens, only Ctrl+D/Ctrl+\ work).

2. MCP stdio subprocess PID tracking (mcp_tool.py): Tracks child PIDs spawned
   by stdio_client via before/after snapshots of /proc children. On shutdown,
   _stop_mcp_loop force-kills any tracked PIDs that survived the SDK's graceful
   SIGTERM→SIGKILL cleanup. Prevents zombie MCP server processes from
   accumulating across sessions.

3. MCP event loop exception handler (mcp_tool.py): Installs
   _mcp_loop_exception_handler on the MCP background event loop — same pattern
   as the existing _suppress_closed_loop_errors on prompt_toolkit's loop.
   Suppresses benign 'Event loop is closed' RuntimeError from httpx transport
   __del__ during MCP shutdown. Salvaged from PR #2538 (acsezen).

4. MCP OAuth non-blocking (mcp_oauth.py): Replaces blocking input() call in
   _wait_for_callback with OAuthNonInteractiveError raise. Adds _is_interactive()
   TTY detection. In non-interactive environments, build_oauth_auth() still
   returns a provider (cached tokens + refresh work), but the callback handler
   raises immediately instead of blocking the MCP event loop for 120s. Re-raises
   OAuth setup failures in _run_http so failed servers are reported cleanly
   without blocking others. Salvaged from PRs #4521 (voidborne-d) and #4465
   (heathley).

Closes #2537, closes #4462

4d99305345 fix(cli): surface recent sessions inside /history and /resume
When /history is used in an empty chat or /resume with no argument,
show an inline table of recent resumable sessions with title, preview,
relative timestamp, and session ID instead of a dead-end message.

Table formatting matches the existing hermes sessions list style
(column headers + thin separators, no box drawing).

924bc67eee feat(memory): pluggable memory provider interface with profile isolation, review fixes, and honcho CLI restoration (#4623)
* feat(memory): add pluggable memory provider interface with profile isolation

Introduces a pluggable MemoryProvider ABC so external memory backends can
integrate with Hermes without modifying core files. Each backend becomes a
plugin implementing a standard interface, orchestrated by MemoryManager.

Key architecture:
- agent/memory_provider.py — ABC with core + optional lifecycle hooks
- agent/memory_manager.py — single integration point in the agent loop
- agent/builtin_memory_provider.py — wraps existing MEMORY.md/USER.md

Profile isolation fixes applied to all 6 shipped plugins:
- Cognitive Memory: use get_hermes_home() instead of raw env var
- Hindsight Memory: check $HERMES_HOME/hindsight/config.json first,
  fall back to legacy ~/.hindsight/ for backward compat
- Hermes Memory Store: replace hardcoded ~/.hermes paths with
  get_hermes_home() for config loading and DB path defaults
- Mem0 Memory: use get_hermes_home() instead of raw env var
- RetainDB Memory: auto-derive profile-scoped project name from
  hermes_home path (hermes-<profile>), explicit env var overrides
- OpenViking Memory: read-only, no local state, isolation via .env

MemoryManager.initialize_all() now injects hermes_home into kwargs so
every provider can resolve profile-scoped storage without importing
get_hermes_home() themselves.

Plugin system: adds register_memory_provider() to PluginContext and
get_plugin_memory_providers() accessor.

Based on PR #3825. 46 tests (37 unit + 5 E2E + 4 plugin registration).

* refactor(memory): drop cognitive plugin, rewrite OpenViking as full provider

Remove cognitive-memory plugin (#727) — core mechanics are broken:
decay runs 24x too fast (hourly not daily), prefetch uses row ID as
timestamp, search limited by importance not similarity.

Rewrite openviking-memory plugin from a read-only search wrapper into
a full bidirectional memory provider using the complete OpenViking
session lifecycle API:

- sync_turn: records user/assistant messages to OpenViking session
  (threaded, non-blocking)
- on_session_end: commits session to trigger automatic memory extraction
  into 6 categories (profile, preferences, entities, events, cases,
  patterns)
- prefetch: background semantic search via find() endpoint
- on_memory_write: mirrors built-in memory writes to the session
- is_available: checks env var only, no network calls (ABC compliance)

Tools expanded from 3 to 5:
- viking_search: semantic search with mode/scope/limit
- viking_read: tiered content (abstract ~100tok / overview ~2k / full)
- viking_browse: filesystem-style navigation (list/tree/stat)
- viking_remember: explicit memory storage via session
- viking_add_resource: ingest URLs/docs into knowledge base

Uses direct HTTP via httpx (no openviking SDK dependency needed).
Response truncation on viking_read to prevent context flooding.

* fix(memory): harden Mem0 plugin — thread safety, non-blocking sync, circuit breaker

- Remove redundant mem0_context tool (identical to mem0_search with
  rerank=true, top_k=5 — wastes a tool slot and confuses the model)
- Thread sync_turn so it's non-blocking — Mem0's server-side LLM
  extraction can take 5-10s, was stalling the agent after every turn
- Add threading.Lock around _get_client() for thread-safe lazy init
  (prefetch and sync threads could race on first client creation)
- Add circuit breaker: after 5 consecutive API failures, pause calls
  for 120s instead of hammering a down server every turn. Auto-resets
  after cooldown. Logs a warning when tripped.
- Track success/failure in prefetch, sync_turn, and all tool calls
- Wait for previous sync to finish before starting a new one (prevents
  unbounded thread accumulation on rapid turns)
- Clean up shutdown to join both prefetch and sync threads

* fix(memory): enforce single external memory provider limit

MemoryManager now rejects a second non-builtin provider with a warning.
Built-in memory (MEMORY.md/USER.md) is always accepted. Only ONE
external plugin provider is allowed at a time. This prevents tool
schema bloat (some providers add 3-5 tools each) and conflicting
memory backends.

The warning message directs users to configure memory.provider in
config.yaml to select which provider to activate.

Updated all 47 tests to use builtin + one external pattern instead
of multiple externals. Added test_second_external_rejected to verify
the enforcement.

* feat(memory): add ByteRover memory provider plugin

Implements the ByteRover integration (from PR #3499 by hieuntg81) as a
MemoryProvider plugin instead of direct run_agent.py modifications.

ByteRover provides persistent memory via the brv CLI — a hierarchical
knowledge tree with tiered retrieval (fuzzy text then LLM-driven search).
Local-first with optional cloud sync.

Plugin capabilities:
- prefetch: background brv query for relevant context
- sync_turn: curate conversation turns (threaded, non-blocking)
- on_memory_write: mirror built-in memory writes to brv
- on_pre_compress: extract insights before context compression

Tools (3):
- brv_query: search the knowledge tree
- brv_curate: store facts/decisions/patterns
- brv_status: check CLI version and context tree state

Profile isolation: working directory at $HERMES_HOME/byterover/ (scoped
per profile). Binary resolution cached with thread-safe double-checked
locking. All write operations threaded to avoid blocking the agent
(curate can take 120s with LLM processing).

* fix(memory): thread remaining sync_turns, fix holographic, add config key

Plugin fixes:
- Hindsight: thread sync_turn (was blocking up to 30s via _run_in_thread)
- RetainDB: thread sync_turn (was blocking on HTTP POST)
- Both: shutdown now joins sync threads alongside prefetch threads

Holographic retrieval fixes:
- reason(): removed dead intersection_key computation (bundled but never
  used in scoring). Now reuses pre-computed entity_residuals directly,
  moved role_content encoding outside the inner loop.
- contradict(): added _MAX_CONTRADICT_FACTS=500 scaling guard. Above
  500 facts, only checks the most recently updated ones to avoid O(n^2)
  explosion (~125K comparisons at 500 is acceptable).

Config:
- Added memory.provider key to DEFAULT_CONFIG ("" = builtin only).
  No version bump needed (deep_merge handles new keys automatically).

* feat(memory): extract Honcho as a MemoryProvider plugin

Creates plugins/honcho-memory/ as a thin adapter over the existing
honcho_integration/ package. All 4 Honcho tools (profile, search,
context, conclude) move from the normal tool registry to the
MemoryProvider interface.

The plugin delegates all work to HonchoSessionManager — no Honcho
logic is reimplemented. It uses the existing config chain:
$HERMES_HOME/honcho.json -> ~/.honcho/config.json -> env vars.

Lifecycle hooks:
- initialize: creates HonchoSessionManager via existing client factory
- prefetch: background dialectic query
- sync_turn: records messages + flushes to API (threaded)
- on_memory_write: mirrors user profile writes as conclusions
- on_session_end: flushes all pending messages

This is a prerequisite for the MemoryManager wiring in run_agent.py.
Once wired, Honcho goes through the same provider interface as all
other memory plugins, and the scattered Honcho code in run_agent.py
can be consolidated into the single MemoryManager integration point.

* feat(memory): wire MemoryManager into run_agent.py

Adds 8 integration points for the external memory provider plugin,
all purely additive (zero existing code modified):

1. Init (~L1130): Create MemoryManager, find matching plugin provider
   from memory.provider config, initialize with session context
2. Tool injection (~L1160): Append provider tool schemas to self.tools
   and self.valid_tool_names after memory_manager init
3. System prompt (~L2705): Add external provider's system_prompt_block
   alongside existing MEMORY.md/USER.md blocks
4. Tool routing (~L5362): Route provider tool calls through
   memory_manager.handle_tool_call() before the catchall handler
5. Memory write bridge (~L5353): Notify external provider via
   on_memory_write() when the built-in memory tool writes
6. Pre-compress (~L5233): Call on_pre_compress() before context
   compression discards messages
7. Prefetch (~L6421): Inject provider prefetch results into the
   current-turn user message (same pattern as Honcho turn context)
8. Turn sync + session end (~L8161, ~L8172): sync_all() after each
   completed turn, queue_prefetch_all() for next turn, on_session_end()
   + shutdown_all() at conversation end

All hooks are wrapped in try/except — a failing provider never breaks
the agent. The existing memory system, Honcho integration, and all
other code paths are completely untouched.

Full suite: 7222 passed, 4 pre-existing failures.

* refactor(memory): remove legacy Honcho integration from core

Extracts all Honcho-specific code from run_agent.py, model_tools.py,
toolsets.py, and gateway/run.py. Honcho is now exclusively available
as a memory provider plugin (plugins/honcho-memory/).

Removed from run_agent.py (-457 lines):
- Honcho init block (session manager creation, activation, config)
- 8 Honcho methods: _honcho_should_activate, _strip_honcho_tools,
  _activate_honcho, _register_honcho_exit_hook, _queue_honcho_prefetch,
  _honcho_prefetch, _honcho_save_user_observation, _honcho_sync
- _inject_honcho_turn_context module-level function
- Honcho system prompt block (tool descriptions, CLI commands)
- Honcho context injection in api_messages building
- Honcho params from __init__ (honcho_session_key, honcho_manager,
  honcho_config)
- HONCHO_TOOL_NAMES constant
- All honcho-specific tool dispatch forwarding

Removed from other files:
- model_tools.py: honcho_tools import, honcho params from handle_function_call
- toolsets.py: honcho toolset definition, honcho tools from core tools list
- gateway/run.py: honcho params from AIAgent constructor calls

Removed tests (-339 lines):
- 9 Honcho-specific test methods from test_run_agent.py
- TestHonchoAtexitFlush class from test_exit_cleanup_interrupt.py

Restored two regex constants (_SURROGATE_RE, _BUDGET_WARNING_RE) that
were accidentally removed during the honcho function extraction.

The honcho_integration/ package is kept intact — the plugin delegates
to it. tools/honcho_tools.py registry entries are now dead code (import
commented out in model_tools.py) but the file is preserved for reference.

Full suite: 7207 passed, 4 pre-existing failures. Zero regressions.

* refactor(memory): restructure plugins, add CLI, clean gateway, migration notice

Plugin restructure:
- Move all memory plugins from plugins/<name>-memory/ to plugins/memory/<name>/
  (byterover, hindsight, holographic, honcho, mem0, openviking, retaindb)
- New plugins/memory/__init__.py discovery module that scans the directory
  directly, loading providers by name without the general plugin system
- run_agent.py uses load_memory_provider() instead of get_plugin_memory_providers()

CLI wiring:
- hermes memory setup — interactive curses picker + config wizard
- hermes memory status — show active provider, config, availability
- hermes memory off — disable external provider (built-in only)
- hermes honcho — now shows migration notice pointing to hermes memory setup

Gateway cleanup:
- Remove _get_or_create_gateway_honcho (already removed in prev commit)
- Remove _shutdown_gateway_honcho and _shutdown_all_gateway_honcho methods
- Remove all calls to shutdown methods (4 call sites)
- Remove _honcho_managers/_honcho_configs dict references

Dead code removal:
- Delete tools/honcho_tools.py (279 lines, import was already commented out)
- Delete tests/gateway/test_honcho_lifecycle.py (131 lines, tested removed methods)
- Remove if False placeholder from run_agent.py

Migration:
- Honcho migration notice on startup: detects existing honcho.json or
  ~/.honcho/config.json, prints guidance to run hermes memory setup.
  Only fires when memory.provider is not set and not in quiet mode.

Full suite: 7203 passed, 4 pre-existing failures. Zero regressions.

* feat(memory): standardize plugin config + add per-plugin documentation

Config architecture:
- Add save_config(values, hermes_home) to MemoryProvider ABC
- Honcho: writes to $HERMES_HOME/honcho.json (SDK native)
- Mem0: writes to $HERMES_HOME/mem0.json
- Hindsight: writes to $HERMES_HOME/hindsight/config.json
- Holographic: writes to config.yaml under plugins.hermes-memory-store
- OpenViking/RetainDB/ByteRover: env-var only (default no-op)

Setup wizard (hermes memory setup):
- Now calls provider.save_config() for non-secret config
- Secrets still go to .env via env vars
- Only memory.provider activation key goes to config.yaml

Documentation:
- README.md for each of the 7 providers in plugins/memory/<name>/
- Requirements, setup (wizard + manual), config reference, tools table
- Consistent format across all providers

The contract for new memory plugins:
- get_config_schema() declares all fields (REQUIRED)
- save_config() writes native config (REQUIRED if not env-var-only)
- Secrets use env_var field in schema, written to .env by wizard
- README.md in the plugin directory

* docs: add memory providers user guide + developer guide

New pages:
- user-guide/features/memory-providers.md — comprehensive guide covering
  all 7 shipped providers (Honcho, OpenViking, Mem0, Hindsight,
  Holographic, RetainDB, ByteRover). Each with setup, config, tools,
  cost, and unique features. Includes comparison table and profile
  isolation notes.
- developer-guide/memory-provider-plugin.md — how to build a new memory
  provider plugin. Covers ABC, required methods, config schema,
  save_config, threading contract, profile isolation, testing.

Updated pages:
- user-guide/features/memory.md — replaced Honcho section with link to
  new Memory Providers page
- user-guide/features/honcho.md — replaced with migration redirect to
  the new Memory Providers page
- sidebars.ts — added both new pages to navigation

* fix(memory): auto-migrate Honcho users to memory provider plugin

When honcho.json or ~/.honcho/config.json exists but memory.provider
is not set, automatically set memory.provider: honcho in config.yaml
and activate the plugin. The plugin reads the same config files, so
all data and credentials are preserved. Zero user action needed.

Persists the migration to config.yaml so it only fires once. Prints
a one-line confirmation in non-quiet mode.

* fix(memory): only auto-migrate Honcho when enabled + credentialed

Check HonchoClientConfig.enabled AND (api_key OR base_url) before
auto-migrating — not just file existence. Prevents false activation
for users who disabled Honcho, stopped using it (config lingers),
or have ~/.honcho/ from a different tool.

* feat(memory): auto-install pip dependencies during hermes memory setup

Reads pip_dependencies from plugin.yaml, checks which are missing,
installs them via pip before config walkthrough. Also shows install
guidance for external_dependencies (e.g. brv CLI for ByteRover).

Updated all 7 plugin.yaml files with pip_dependencies:
- honcho: honcho-ai
- mem0: mem0ai
- openviking: httpx
- hindsight: hindsight-client
- holographic: (none)
- retaindb: requests
- byterover: (external_dependencies for brv CLI)

* fix: remove remaining Honcho crash risks from cli.py and gateway

cli.py: removed Honcho session re-mapping block (would crash importing
deleted tools/honcho_tools.py), Honcho flush on compress, Honcho
session display on startup, Honcho shutdown on exit, honcho_session_key
AIAgent param.

gateway/run.py: removed honcho_session_key params from helper methods,
sync_honcho param, _honcho.shutdown() block.

tests: fixed test_cron_session_with_honcho_key_skipped (was passing
removed honcho_key param to _flush_memories_for_session).

* fix: include plugins/ in pyproject.toml package list

Without this, plugins/memory/ wouldn't be included in non-editable
installs. Hermes always runs from the repo checkout so this is belt-
and-suspenders, but prevents breakage if the install method changes.

* fix(memory): correct pip-to-import name mapping for dep checks

The heuristic dep.replace('-', '_') fails for packages where the pip
name differs from the import name: honcho-ai→honcho, mem0ai→mem0,
hindsight-client→hindsight_client. Added explicit mapping table so
hermes memory setup doesn't try to reinstall already-installed packages.

* chore: remove dead code from old plugin memory registration path

- hermes_cli/plugins.py: removed register_memory_provider(),
  _memory_providers list, get_plugin_memory_providers() — memory
  providers now use plugins/memory/ discovery, not the general plugin system
- hermes_cli/main.py: stripped 74 lines of dead honcho argparse
  subparsers (setup, status, sessions, map, peer, mode, tokens,
  identity, migrate) — kept only the migration redirect
- agent/memory_provider.py: updated docstring to reflect new
  registration path
- tests: replaced TestPluginMemoryProviderRegistration with
  TestPluginMemoryDiscovery that tests the actual plugins/memory/
  discovery system. Added 3 new tests (discover, load, nonexistent).

* chore: delete dead honcho_integration/cli.py and its tests

cli.py (794 lines) was the old 'hermes honcho' command handler — nobody
calls it since cmd_honcho was replaced with a migration redirect.

Deleted tests that imported from removed code:
- tests/honcho_integration/test_cli.py (tested _resolve_api_key)
- tests/honcho_integration/test_config_isolation.py (tested CLI config paths)
- tests/tools/test_honcho_tools.py (tested the deleted tools/honcho_tools.py)

Remaining honcho_integration/ files (actively used by the plugin):
- client.py (445 lines) — config loading, SDK client creation
- session.py (991 lines) — session management, queries, flush

* refactor: move honcho_integration/ into the honcho plugin

Moves client.py (445 lines) and session.py (991 lines) from the
top-level honcho_integration/ package into plugins/memory/honcho/.
No Honcho code remains in the main codebase.

- plugins/memory/honcho/client.py — config loading, SDK client creation
- plugins/memory/honcho/session.py — session management, queries, flush
- Updated all imports: run_agent.py (auto-migration), hermes_cli/doctor.py,
  plugin __init__.py, session.py cross-import, all tests
- Removed honcho_integration/ package and pyproject.toml entry
- Renamed tests/honcho_integration/ → tests/honcho_plugin/

* docs: update architecture + gateway-internals for memory provider system

- architecture.md: replaced honcho_integration/ with plugins/memory/
- gateway-internals.md: replaced Honcho-specific session routing and
  flush lifecycle docs with generic memory provider interface docs

* fix: update stale mock path for resolve_active_host after honcho plugin migration

* fix(memory): address review feedback — P0 lifecycle, ABC contract, honcho CLI restore

Review feedback from Honcho devs (erosika):

P0 — Provider lifecycle:
- Remove on_session_end() + shutdown_all() from run_conversation() tail
  (was killing providers after every turn in multi-turn sessions)
- Add shutdown_memory_provider() method on AIAgent for callers
- Wire shutdown into CLI atexit, reset_conversation, gateway stop/expiry

Bug fixes:
- Remove sync_honcho=False kwarg from /btw callsites (TypeError crash)
- Fix doctor.py references to dead 'hermes honcho setup' command
- Cache prefetch_all() before tool loop (was re-calling every iteration)

ABC contract hardening (all backwards-compatible):
- Add session_id kwarg to prefetch/sync_turn/queue_prefetch
- Make on_pre_compress() return str (provider insights in compression)
- Add **kwargs to on_turn_start() for runtime context
- Add on_delegation() hook for parent-side subagent observation
- Document agent_context/agent_identity/agent_workspace kwargs on
  initialize() (prevents cron corruption, enables profile scoping)
- Fix docstring: single external provider, not multiple

Honcho CLI restoration:
- Add plugins/memory/honcho/cli.py (from main's honcho_integration/cli.py
  with imports adapted to plugin path)
- Restore full hermes honcho command with all subcommands (status, peer,
  mode, tokens, identity, enable/disable, sync, peers, --target-profile)
- Restore auto-clone on profile creation + sync on hermes update
- hermes honcho setup now redirects to hermes memory setup

* fix(memory): wire on_delegation, skip_memory for cron/flush, fix ByteRover return type

- Wire on_delegation() in delegate_tool.py — parent's memory provider
  is notified with task+result after each subagent completes
- Add skip_memory=True to cron scheduler (prevents cron system prompts
  from corrupting user representations — closes #4052)
- Add skip_memory=True to gateway flush agent (throwaway agent shouldn't
  activate memory provider)
- Fix ByteRover on_pre_compress() return type: None -> str

* fix(honcho): port profile isolation fixes from PR #4632

Ports 5 bug fixes found during profile testing (erosika's PR #4632):

1. 3-tier config resolution — resolve_config_path() now checks
   $HERMES_HOME/honcho.json → ~/.hermes/honcho.json → ~/.honcho/config.json
   (non-default profiles couldn't find shared host blocks)

2. Thread host=_host_key() through from_global_config() in cmd_setup,
   cmd_status, cmd_identity (--target-profile was being ignored)

3. Use bare profile name as aiPeer (not host key with dots) — Honcho's
   peer ID pattern is ^[a-zA-Z0-9_-]+$, dots are invalid

4. Wrap add_peers() in try/except — was fatal on new AI peers, killed
   all message uploads for the session

5. Gate Honcho clone behind --clone/--clone-all on profile create
   (bare create should be blank-slate)

Also: sanitize assistant_peer_id via _sanitize_id()

* fix(tests): add module cleanup fixture to test_cli_provider_resolution

test_cli_provider_resolution._import_cli() wipes tools.*, cli, and
run_agent from sys.modules to force fresh imports, but had no cleanup.
This poisoned all subsequent tests on the same xdist worker — mocks
targeting tools.file_tools, tools.send_message_tool, etc. patched the
NEW module object while already-imported functions still referenced
the OLD one. Caused ~25 cascade failures: send_message KeyError,
process_registry FileNotFoundError, file_read_guards timeouts,
read_loop_detection file-not-found, mcp_oauth None port, and
provider_parity/codex_execution stale tool lists.

Fix: autouse fixture saves all affected modules before each test and
restores them after, matching the pattern in
test_managed_browserbase_and_modal.py.

28a073edc6 fix: repair OpenCode model routing and selection (#4508)
OpenCode Zen and Go are mixed-API-surface providers — different models
behind them use different API surfaces (GPT on Zen uses codex_responses,
Claude on Zen uses anthropic_messages, MiniMax on Go uses
anthropic_messages, GLM/Kimi on Go use chat_completions).

Changes:
- Add normalize_opencode_model_id() and opencode_model_api_mode() to
  models.py for model ID normalization and API surface routing
- Add _provider_supports_explicit_api_mode() to runtime_provider.py
  to prevent stale api_mode from leaking across provider switches
- Wire opencode routing into all three api_mode resolution paths:
  pool entry, api_key provider, and explicit runtime
- Add api_mode field to ModelSwitchResult for propagation through the
  switch pipeline
- Consolidate _PROVIDER_MODELS from main.py into models.py (single
  source of truth, eliminates duplicate dict)
- Add opencode normalization to setup wizard and model picker flows
- Add opencode block to _normalize_model_for_provider in CLI
- Add opencode-zen/go fallback model lists to setup.py

Tests: 160 targeted tests pass (26 new tests covering normalization,
api_mode routing per provider/model, persistence, and setup wizard
normalization).

c4e626b1fa refactor: extract _detect_file_drop() + add 28 tests
Extract the inline file-drop detection logic into a standalone
_detect_file_drop() function at module level for testability. The main
loop now calls this function instead of inlining the logic.

Tests cover:
- Slash commands still route correctly (/help, /quit, /xyz)
- Image paths auto-detected (.png, .jpg, .gif, etc.)
- Non-image files detected (.py, .txt, Makefile, etc.)
- Backslash-escaped spaces from macOS drag-and-drop
- Trailing user text preserved as remainder
- Edge cases: directories, symlinks, no-extension files
- Non-string input, empty strings, nonexistent paths

1841886898 fix(cli): detect dragged file paths instead of treating them as slash commands
When a user drags a file into the terminal, macOS pastes the absolute
path (e.g. /Users/roland/Desktop/Screenshot.png) which starts with '/'
and was incorrectly routed to process_command(), producing an 'Unknown
command' error.

This change adds file-path detection before the slash-command check:
- Parses the first token, handling backslash-escaped spaces from macOS
- Checks if the path exists as a real file via Path.exists()
- Image files (.png, .jpg, etc.) are auto-attached to the message
- Non-image files are reformatted as [User attached file: ...] context
- Falls through to normal slash-command handling if not a real file path

de9bba8d7c fix: remove hardcoded OpenRouter/opus defaults
No model, base_url, or provider is assumed when the user hasn't
configured one.  Previously the defaults dict in cli.py, AIAgent
constructor args, and several fallback paths all hardcoded
anthropic/claude-opus-4.6 + openrouter.ai/api/v1 — silently routing
unconfigured users to OpenRouter, which 404s for anyone using a
different provider.

Now empty defaults force the setup wizard to run, and existing users
who already completed setup are unaffected (their config.yaml has
the model they chose).

Files changed:
- cli.py: defaults dict, _DEFAULT_CONFIG_MODEL
- run_agent.py: AIAgent.__init__ defaults, main() defaults
- hermes_cli/config.py: DEFAULT_CONFIG
- hermes_cli/runtime_provider.py: is_fallback sentinel
- acp_adapter/session.py: default_model
- tests: updated to reflect empty defaults

c59ab8b0da fix: profile model.model promoted to model.default when default not set
When a profile config sets model.model but not model.default, the
hardcoded default (claude-opus-4.6) survived the config merge and
took precedence in HermesCLI.__init__ because it checks model.default
first. Profile model configs were silently ignored.

Now model.model is promoted to model.default during the merge when the
user didn't explicitly set model.default. Fixes #4486.

16d9f58445 fix(gateway): persist memory flush state to prevent redundant re-flushes on restart (#4481)
* fix: force-close TCP sockets on client cleanup, detect and recover dead connections

When a provider drops connections mid-stream (e.g. OpenRouter outage),
httpx's graceful close leaves sockets in CLOSE-WAIT indefinitely. These
zombie connections accumulate and can prevent recovery without restarting.

Changes:
- _force_close_tcp_sockets: walks the httpx connection pool and issues
  socket.shutdown(SHUT_RDWR) + close() to force TCP RST on every socket
  when a client is closed, preventing CLOSE-WAIT accumulation
- _cleanup_dead_connections: probes the primary client's pool for dead
  sockets (recv MSG_PEEK), rebuilds the client if any are found
- Pre-turn health check at the start of each run_conversation call that
  auto-recovers with a user-facing status message
- Primary client rebuild after stale stream detection to purge pool
- User-facing messages on streaming connection failures:
  "Connection to provider dropped — Reconnecting (attempt 2/3)"
  "Connection failed after 3 attempts — try again in a moment"

Made-with: Cursor

* fix: pool entry missing base_url for openrouter, clean error messages

- _resolve_runtime_from_pool_entry: add OPENROUTER_BASE_URL fallback
  when pool entry has no runtime_base_url (pool entries from auth.json
  credential_pool often omit base_url)
- Replace Rich console.print for auth errors with plain print() to
  prevent ANSI escape code mangling through prompt_toolkit's stdout patch
- Force-close TCP sockets on client cleanup to prevent CLOSE-WAIT
  accumulation after provider outages
- Pre-turn dead connection detection with auto-recovery and user message
- Primary client rebuild after stale stream detection
- User-facing status messages on streaming connection failures/retries

* fix(gateway): persist memory flush state to prevent redundant re-flushes on restart

The _session_expiry_watcher tracked flushed sessions in an in-memory set
(_pre_flushed_sessions) that was lost on gateway restart. Expired sessions
remained in sessions.json and were re-discovered every restart, causing
redundant AIAgent runs that burned API credits and blocked the event loop.

Fix: Add a memory_flushed boolean field to SessionEntry, persisted in
sessions.json. The watcher sets it after a successful flush. On restart,
the flag survives and the watcher skips already-flushed sessions.

- Add memory_flushed field to SessionEntry with to_dict/from_dict support
- Old sessions.json entries without the field default to False (backward compat)
- Remove the ephemeral _pre_flushed_sessions set from SessionStore
- Update tests: save/load roundtrip, legacy entry compat, auto-reset behavior

935137f0d9 feat: add inline diff previews for write actions
Show inline diffs in the CLI transcript when write_file, patch, or
skill_manage modifies files. Captures a filesystem snapshot before the
tool runs, computes a unified diff after, and renders it with ANSI
coloring in the activity feed.

Adds tool_start_callback and tool_complete_callback hooks to AIAgent
for pre/post tool execution notifications.

Also fixes _extract_parallel_scope_path to normalize relative paths
to absolute, preventing the parallel overlap detection from missing
conflicts when the same file is referenced with different path styles.

Gated by display.inline_diffs config option (default: true).

996250d178 fix(cli): pin entire TUI to bottom of terminal on startup (#4412)
Replace the per-response padding from PR #4359 (which created a void
between short responses and the prompt) with a one-time initial scroll
at session start.  Prints terminal_height newlines before the banner so
the cursor starts at the bottom row — banner, responses, and prompt all
appear pinned to the bottom with empty space above, not below.

patch_stdout naturally keeps the prompt at the bottom from there, so
no per-response padding is needed.

a7f7e87070 fix: preserve credential_pool through smart routing and defer eager fallback on 429 (#4361)
Three bugs prevented credential pool rotation from working when multiple
Codex OAuth tokens were configured:

1. credential_pool was dropped during smart model turn routing.
   resolve_turn_route() constructed runtime dicts without it, so the
   AIAgent was created without pool access. Fixed in smart_model_routing.py
   (no-route and fallback paths), cli.py, and gateway/run.py.

2. Eager fallback fired before pool rotation on 429. The rate-limit
   handler at line ~7180 switched to a fallback provider immediately,
   before _recover_with_credential_pool got a chance to rotate to the
   next credential. Now deferred when the pool still has credentials.

3. (Non-issue) Retry budget was reported as too small, but successful
   pool rotations already skip retry_count increment — no change needed.

Reported by community member Schinsly who identified all three root
causes and verified the fix locally with multiple Codex accounts.

1b62ad9de7 fix: root-level provider in config.yaml no longer overrides model.provider
load_cli_config() had a priority inversion: a stale root-level
'provider' key in config.yaml would OVERRIDE the canonical
'model.provider' set by 'hermes model'. The gateway reads
model.provider directly from YAML and worked correctly, but
'hermes chat -q' and the interactive CLI went through the merge
logic and picked up the stale root-level key.

Fix: root-level provider/base_url are now only used as a fallback
when model.provider/model.base_url is not set (never as an override).

Also added _normalize_root_model_keys() to config.py load_config()
and save_config() — migrates root-level provider/base_url into the
model section and removes the root-level keys permanently.

Reported by (≧▽≦) in Discord: opencode-go provider persisted as a
root-level key and overrode the correct model.provider=openrouter,
causing 401 errors.

config.yaml is left empty. Replace with atomic_yaml_write() (temp file +
fsync + os.replace), matching the gateway config write path.

57625329a2 docs+feat: comprehensive local LLM provider guides and context length warning (#4294)
* docs: update llama.cpp section with --jinja flag and tool calling guide

The llama.cpp docs were missing the --jinja flag which is required for
tool calling to work. Without it, models output tool calls as raw JSON
text instead of structured API responses, making Hermes unable to
execute them.

Changes:
- Add --jinja and -fa flags to the server startup example
- Replace deprecated env vars (OPENAI_BASE_URL, LLM_MODEL) with
  hermes model interactive setup
- Add caution block explaining the --jinja requirement and symptoms
- List models with native tool calling support
- Add /props endpoint verification tip

* docs+feat: comprehensive local LLM provider guides and context length warning

Docs (providers.md):
- Rewrote Ollama section with context length warning (defaults to 4k on
  <24GB VRAM), three methods to increase it, and verification steps
- Rewrote vLLM section with --max-model-len, tool calling flags
  (--enable-auto-tool-choice, --tool-call-parser), and context guidance
- Rewrote SGLang section with --context-length, --tool-call-parser,
  and warning about 128-token default max output
- Added LM Studio section (port 1234, context length defaults to 2048,
  tool calling since 0.3.6)
- Added llama.cpp context length flag (-c) and GPU offload (-ngl)
- Added Troubleshooting Local Models section covering:
  - Tool calls appearing as text (with per-server fix table)
  - Silent context truncation and diagnosis commands
  - Low detected context at startup
  - Truncated responses
- Replaced all deprecated env vars (OPENAI_BASE_URL, LLM_MODEL) with
  hermes model interactive setup and config.yaml examples
- Added deprecation warning for legacy env vars in General Setup

Code (cli.py):
- Added context length warning in show_banner() when detected context
  is <= 8192 tokens, with server-specific fix hints:
  - Ollama (port 11434): suggests OLLAMA_CONTEXT_LENGTH env var
  - LM Studio (port 1234): suggests model settings adjustment
  - Other servers: suggests config.yaml override

Tests:
- 9 new tests covering warning thresholds, server-specific hints,
  and no-warning cases

8d59881a62 feat(auth): same-provider credential pools with rotation, custom endpoint support, and interactive CLI (#2647)
* feat(auth): add same-provider credential pools and rotation UX

Add same-provider credential pooling so Hermes can rotate across
multiple credentials for a single provider, recover from exhausted
credentials without jumping providers immediately, and configure
that behavior directly in hermes setup.

- agent/credential_pool.py: persisted per-provider credential pools
- hermes auth add/list/remove/reset CLI commands
- 429/402/401 recovery with pool rotation in run_agent.py
- Setup wizard integration for pool strategy configuration
- Auto-seeding from env vars and existing OAuth state

Salvaged from PR #2647

* fix(tests): prevent pool auto-seeding from host env in credential pool tests

Tests for non-pool Anthropic paths and auth remove were failing when
host env vars (ANTHROPIC_API_KEY) or file-backed OAuth credentials
were present. The pool auto-seeding picked these up, causing unexpected
pool entries in tests.

- Mock _select_pool_entry in auxiliary_client OAuth flag tests
- Clear Anthropic env vars and mock _seed_from_singletons in auth remove test

* feat(auth): add thread safety, least_used strategy, and request counting

- Add threading.Lock to CredentialPool for gateway thread safety
  (concurrent requests from multiple gateway sessions could race on
  pool state mutations without this)
- Add 'least_used' rotation strategy that selects the credential
  with the lowest request_count, distributing load more evenly
- Add request_count field to PooledCredential for usage tracking
- Add mark_used() method to increment per-credential request counts
- Wrap select(), mark_exhausted_and_rotate(), and try_refresh_current()
  with lock acquisition
- Add tests: least_used selection, mark_used counting, concurrent
  thread safety (4 threads × 20 selects with no corruption)

* feat(auth): add interactive mode for bare 'hermes auth' command

When 'hermes auth' is called without a subcommand, it now launches an
interactive wizard that:

1. Shows full credential pool status across all providers
2. Offers a menu: add, remove, reset cooldowns, set strategy
3. For OAuth-capable providers (anthropic, nous, openai-codex), the
   add flow explicitly asks 'API key or OAuth login?' — making it
   clear that both auth types are supported for the same provider
4. Strategy picker shows all 4 options (fill_first, round_robin,
   least_used, random) with the current selection marked
5. Remove flow shows entries with indices for easy selection

The subcommand paths (hermes auth add/list/remove/reset) still work
exactly as before for scripted/non-interactive use.

* fix(tests): update runtime_provider tests for config.yaml source of truth (#4165)

Tests were using OPENAI_BASE_URL env var which is no longer consulted
after #4165. Updated to use model config (provider, base_url, api_key)
which is the new single source of truth for custom endpoint URLs.

* feat(auth): support custom endpoint credential pools keyed by provider name

Custom OpenAI-compatible endpoints all share provider='custom', making
the provider-keyed pool useless. Now pools for custom endpoints are
keyed by 'custom:<normalized_name>' where the name comes from the
custom_providers config list (auto-generated from URL hostname).

- Pool key format: 'custom:together.ai', 'custom:local-(localhost:8080)'
- load_pool('custom:name') seeds from custom_providers api_key AND
  model.api_key when base_url matches
- hermes auth add/list now shows custom endpoints alongside registry
  providers
- _resolve_openrouter_runtime and _resolve_named_custom_runtime check
  pool before falling back to single config key
- 6 new tests covering custom pool keying, seeding, and listing

* docs: add Excalidraw diagram of full credential pool flow

Comprehensive architecture diagram showing:
- Credential sources (env vars, auth.json OAuth, config.yaml, CLI)
- Pool storage and auto-seeding
- Runtime resolution paths (registry, custom, OpenRouter)
- Error recovery (429 retry-then-rotate, 402 immediate, 401 refresh)
- CLI management commands and strategy configuration

Open at: https://excalidraw.com/#json=2Ycqhqpi6f12E_3ITyiwh,c7u9jSt5BwrmiVzHGbm87g

* fix(tests): update setup wizard pool tests for unified select_provider_and_model flow

The setup wizard now delegates to select_provider_and_model() instead
of using its own prompt_choice-based provider picker. Tests needed:
- Mock select_provider_and_model as no-op (provider pre-written to config)
- Call _stub_tts BEFORE custom prompt_choice mock (it overwrites it)
- Pre-write model.provider to config so the pool step is reached

* docs: add comprehensive credential pool documentation

- New page: website/docs/user-guide/features/credential-pools.md
  Full guide covering quick start, CLI commands, rotation strategies,
  error recovery, custom endpoint pools, auto-discovery, thread safety,
  architecture, and storage format.
- Updated fallback-providers.md to reference credential pools as the
  first layer of resilience (same-provider rotation before cross-provider)
- Added hermes auth to CLI commands reference with usage examples
- Added credential_pool_strategies to configuration guide

* chore: remove excalidraw diagram from repo (external link only)

* refactor: simplify credential pool code — extract helpers, collapse extras, dedup patterns

- _load_config_safe(): replace 4 identical try/except/import blocks
- _iter_custom_providers(): shared generator for custom provider iteration
- PooledCredential.extra dict: collapse 11 round-trip-only fields
  (token_type, scope, client_id, portal_base_url, obtained_at,
  expires_in, agent_key_id, agent_key_expires_in, agent_key_reused,
  agent_key_obtained_at, tls) into a single extra dict with
  __getattr__ for backward-compatible access
- _available_entries(): shared exhaustion-check between select and peek
- Dedup anthropic OAuth seeding (hermes_pkce + claude_code identical)
- SimpleNamespace replaces class _Args boilerplate in auth_commands
- _try_resolve_from_custom_pool(): shared pool-check in runtime_provider

Net -17 lines. All 383 targeted tests pass.

f890a94c12 refactor: make config.yaml the single source of truth for endpoint URLs (#4165)
OPENAI_BASE_URL was written to .env AND config.yaml, creating a dual-source
confusion. Users (especially Docker) would see the URL in .env and assume
that's where all config lives, then wonder why LLM_MODEL in .env didn't work.

Changes:
- Remove all 27 save_env_value("OPENAI_BASE_URL", ...) calls across main.py,
  setup.py, and tools_config.py
- Remove OPENAI_BASE_URL env var reading from runtime_provider.py, cli.py,
  models.py, and gateway/run.py
- Remove LLM_MODEL/HERMES_MODEL env var reading from gateway/run.py and
  auxiliary_client.py — config.yaml model.default is authoritative
- Vision base URL now saved to config.yaml auxiliary.vision.base_url
  (both setup wizard and tools_config paths)
- Tests updated to set config values instead of env vars

Convention enforced: .env is for SECRETS only (API keys). All other
configuration (model names, base URLs, provider selection) lives
exclusively in config.yaml.

1bd206ea5d feat: add /btw command for ephemeral side questions (#4161)
Adds /btw <question> — ask a quick follow-up using the current
session context without interrupting the main conversation.

- Snapshots conversation history, answers with a no-tools agent
- Response is not persisted to session history or DB
- Runs in a background thread (CLI) / async task (gateway)
- Per-session guard prevents concurrent /btw in gateway

Implementation:
- model_tools.py: enabled_toolsets=[] now correctly means "no tools"
  (was falsy, fell through to default "all tools")
- run_agent.py: persist_session=False gates _persist_session()
- cli.py: _handle_btw_command (background thread, Rich panel output)
- gateway/run.py: _handle_btw_command + _run_btw_task (async task)
- hermes_cli/commands.py: CommandDef for "btw"

Inspired by PR #3504 by areu01or00, reimplemented cleanly on current
main with the enabled_toolsets=[] fix and without the __btw_no_tools__
hack.

86ac23c8da fix(auth): stop silently falling back to OpenRouter when no provider is configured (#3862)
Previously, when no API keys or provider credentials were found, Hermes
silently defaulted to OpenRouter + Claude Opus. This caused confusion
when users configured local servers (LM Studio, Ollama, etc.) with a
typo or unrecognized provider name — the system would silently route to
OpenRouter instead of telling them something was wrong.

Changes:
- resolve_provider() now raises AuthError when no credentials are found
  instead of returning 'openrouter' as a silent fallback
- Added local server aliases: lmstudio, ollama, vllm, llamacpp → custom
- Removed hardcoded 'anthropic/claude-opus-4.6' fallback from gateway
  and cron scheduler (they read from config.yaml instead)
- Updated cli-config.yaml.example with complete provider documentation
  including all supported providers, aliases, and local server setup

e314833c9d feat(display): configurable tool preview length -- show full paths by default (#3841)
Tool call previews (paths, commands, queries) were hardcoded to truncate
at 35-40 chars across CLI spinners, completion lines, and gateway progress
messages. Users could not see full file paths in tool output.

New config option: display.tool_preview_length (default 0 = no limit).
Set a positive number to truncate at that length.

Changes:
- display.py: module-level _tool_preview_max_len with getter/setter;
  build_tool_preview() and get_cute_tool_message() _trunc/_path respect it
- cli.py: reads config at startup, spinner widget respects config
- gateway/run.py: reads config per-message, progress callback respects config
- run_agent.py: removed redundant 30-char quiet-mode spinner truncation
- config.py: added display.tool_preview_length to DEFAULT_CONFIG

252fbea005 feat(providers): add ordered fallback provider chain (salvage #1761) (#3813)
Extends the single fallback_model mechanism into an ordered chain.
When the primary model fails, Hermes tries each fallback provider in
sequence until one succeeds or the chain is exhausted.

Config format (new):
  fallback_providers:
    - provider: openrouter
      model: anthropic/claude-sonnet-4
    - provider: openai
      model: gpt-4o

Legacy single-dict fallback_model format still works unchanged.

Key fix vs original PR: the call sites in the retry loop now use
_fallback_index < len(_fallback_chain) instead of the old one-shot
_fallback_activated guard, so the chain actually advances through
all configured providers.

Changes:
- run_agent.py: _fallback_chain list + _fallback_index replaces
  one-shot _fallback_model; _try_activate_fallback() advances
  through chain; failed provider resolution skips to next entry;
  call sites updated to allow chain advancement
- cli.py: reads fallback_providers with legacy fallback_model compat
- gateway/run.py: same
- hermes_cli/config.py: fallback_providers: [] in DEFAULT_CONFIG
- tests: 12 new chain tests + 6 existing test fixtures updated

f6db1b27ba feat: add profiles — run multiple isolated Hermes instances (#3681)
Each profile is a fully independent HERMES_HOME with its own config,
API keys, memory, sessions, skills, gateway, cron, and state.db.

Core module: hermes_cli/profiles.py (~900 lines)
  - Profile CRUD: create, delete, list, show, rename
  - Three clone levels: blank, --clone (config), --clone-all (everything)
  - Export/import: tar.gz archive for backup and migration
  - Wrapper alias scripts (~/.local/bin/<name>)
  - Collision detection for alias names
  - Sticky default via ~/.hermes/active_profile
  - Skill seeding via subprocess (handles module-level caching)
  - Auto-stop gateway on delete with disable-before-stop for services
  - Tab completion generation for bash and zsh

CLI integration (hermes_cli/main.py):
  - _apply_profile_override(): pre-import -p/--profile flag + sticky default
  - Full 'hermes profile' subcommand: list, use, create, delete, show,
    alias, rename, export, import
  - 'hermes completion bash/zsh' command
  - Multi-profile skill sync in hermes update

Display (cli.py, banner.py, gateway/run.py):
  - CLI prompt: 'coder ❯' when using a non-default profile
  - Banner shows profile name
  - Gateway startup log includes profile name

Gateway safety:
  - Token locks: Discord, Slack, WhatsApp, Signal (extends Telegram pattern)
  - Port conflict detection: API server, webhook adapter

Diagnostics (hermes_cli/doctor.py):
  - Profile health section: lists profiles, checks config, .env, aliases
  - Orphan alias detection: warns when wrapper points to deleted profile

Tests (tests/hermes_cli/test_profiles.py):
  - 71 automated tests covering: validation, CRUD, clone levels, rename,
    export/import, active profile, isolation, alias collision, completion
  - Full suite: 6760 passed, 0 new failures

Documentation:
  - website/docs/user-guide/profiles.md: full user guide (12 sections)
  - website/docs/reference/profile-commands.md: command reference (12 commands)
  - website/docs/reference/faq.md: 6 profile FAQ entries
  - website/sidebars.ts: navigation updated

9f01244137 fix: replace user-facing hardcoded ~/.hermes paths with display_hermes_home()
Prep for profiles: user-facing messages now use display_hermes_home() so
diagnostic output shows the correct path for each profile.

New helper: display_hermes_home() in hermes_constants.py
12 files swept, ~30 user-facing string replacements.
Includes dynamic TTS schema description.

0bd7e95dfc fix(honcho): allow self-hosted local instances without API key (#3644)
Self-hosted Honcho on localhost doesn't require authentication, but
both the activation gates and the SDK client required an API key.

Combined fix from three contributor PRs:
- Relax all 8 activation gates to accept (api_key OR base_url) as
  valid credentials (#3482 by @cameronbergh)
- Use 'local' placeholder for the SDK client when base_url points to
  localhost/127.0.0.1/::1 (#3570 by @ygd58)

Files changed: run_agent.py (2 gates), cli.py (1 gate),
gateway/run.py (1 gate), honcho_integration/cli.py (2 gates),
hermes_cli/doctor.py (2 gates), honcho_integration/client.py (SDK).

bea49e02a3 fix: route /bg spinner through TUI widget to prevent status bar collision (#3643)
Background agent's KawaiiSpinner wrote \r-based animation and stop()
messages through StdoutProxy, colliding with prompt_toolkit's status bar.

Two fixes:
- display.py: use isinstance(out, StdoutProxy) instead of fragile
  hasattr+name check for detecting prompt_toolkit's stdout wrapper
- cli.py: silence bg agent's raw spinner (_print_fn=no-op) and route
  thinking updates through the TUI widget only when no foreground
  agent is active; clear spinner text in finally block with same guard

Closes #2718

857a5d7b47 fix: sanitize surrogate characters from clipboard paste to prevent UnicodeEncodeError (#3624)
Pasting text from rich-text editors (Google Docs, Word, etc.) can inject
lone surrogate characters (U+D800..U+DFFF) that are invalid UTF-8.
The OpenAI SDK serializes messages with ensure_ascii=False, then encodes
to UTF-8 for the HTTP body — surrogates crash this with:
  UnicodeEncodeError: 'utf-8' codec can't encode character '\udce2'

Three-layer fix:
1. Primary: sanitize user_message at the top of run_conversation()
2. CLI: sanitize in chat() before appending to conversation_history
3. Safety net: catch UnicodeEncodeError in the API error handler,
   sanitize the entire messages list in-place, and retry once.
   Also exclude UnicodeEncodeError from is_local_validation_error
   so it doesn't get classified as non-retryable.

Includes 14 new tests covering the sanitization helpers and the
integration with run_conversation().

b029742092 fix(cli): strengthen paste collapse fallback for terminals without bracketed paste (#3625)
The _on_text_changed fallback only detected pastes when all characters
arrived in a single event (chars_added > 1).  Some terminals (notably
VSCode integrated terminal in certain configs) may deliver paste data
differently, causing the fallback to miss.

Add a second heuristic: if the newline count jumps by 4+ in a single
text-change event, treat it as a paste.  Alt+Enter only adds 1 newline
per event, so this never false-positives on manual multi-line input.

Also fixes: the fallback path was missing _paste_just_collapsed flag
set before replacing buffer text, which could cause a re-trigger loop.

e4480ff426 fix(config): accept 'model' key as alias for 'default' in model config (#3603)
Users intuitively write model: { model: my-model } instead of
model: { default: my-model } and it silently falls back to the
hardcoded default. Now both spellings work across all three config
consumers: runtime_provider, CLI, and gateway.

Salvage of PR #3533 (binhnt92). Follow-up to #3480 — applies min(100, ...) to 5 remaining unclamped percentage display sites in context_compressor, cli /stats, gateway /stats, and memory tool. Defensive clamps now that the root cause (estimation heuristic) was already removed in #3480.

be39292633 fix(cli): guard .strip() against None values from YAML config (#3552)
dict.get(key, default) only returns default when key is ABSENT.
When YAML has 'key:' with no value, it parses as None — .get()
returns None, then .strip() crashes with AttributeError.

Use (x or '') pattern to handle both missing and null cases.

e4e04c2005 fix: make tirith block verdicts approvable instead of hard-blocking (#3428)
Previously, tirith exit code 1 (block) immediately rejected the command
with no approval prompt — users saw 'BLOCKED: Command blocked by
security scan' and the agent moved on.  This prevented gateway/CLI users
from approving pipe-to-shell installs like 'curl ... | sh' even when
they understood the risk.

Changes:
- Tirith 'block' and 'warn' now both go through the approval flow.
  Users see the full tirith findings (severity, title, description,
  safer alternatives) and can choose to approve or deny.
- New _format_tirith_description() builds rich descriptions from tirith
  findings JSON so the approval prompt is informative.
- CLI startup now warns when tirith is enabled but not available, so
  users know command scanning is degraded to pattern matching only.

The default approval choice is still deny, so the security posture is
unchanged for unattended/timeout scenarios.

Reported via Discord by pistrie — 'curl -fsSL https://mandex.dev/install.sh | sh'
was hard-blocked with no way to approve.

8ecd7aed2c fix: prevent reasoning box from rendering 3x during tool-calling loops (#3405)
Two independent bugs caused the reasoning box to appear three times when
the model produced reasoning + tool_calls:

Bug A: _build_assistant_message() re-fired reasoning_callback with the full
reasoning text even when streaming had already displayed it. The original
guard only checked structured reasoning_content deltas, but reasoning also
arrives via content tag extraction (<REASONING_SCRATCHPAD>/<think> tags
in delta.content), which went through _fire_stream_delta not
_fire_reasoning_delta. Fix: skip the callback entirely when streaming is
active — both paths display reasoning during the stream. Any reasoning not
shown during streaming is caught by the CLI post-response fallback.

Bug B: The post-response reasoning display checked _reasoning_stream_started,
but that flag was reset by _reset_stream_state() during intermediate turn
boundaries (when stream_delta_callback(None) fires between tool calls).
Introduced _reasoning_shown_this_turn flag that persists across the tool
loop and is only reset at the start of each user turn.

Live-tested in PTY: reasoning now shows exactly once per API call, no
duplicates across tool-calling loops.

e0dbbdb2c9 fix: eliminate 'Event loop is closed' / 'Press ENTER to continue' during idle (#3398)
The OpenAI SDK's AsyncHttpxClientWrapper.__del__ schedules aclose() via
asyncio.get_running_loop().create_task().  When an AsyncOpenAI client is
garbage-collected while prompt_toolkit's event loop is running (the common
CLI idle state), the aclose() task runs on prompt_toolkit's loop but the
underlying TCP transport is bound to a different (dead) worker loop.
The transport's self._loop.call_soon() then raises RuntimeError('Event
loop is closed'), which prompt_toolkit surfaces as the disruptive
'Unhandled exception in event loop ... Press ENTER to continue...' error.

Three-layer fix:

1. neuter_async_httpx_del(): Monkey-patches __del__ to a no-op at CLI
   startup before any AsyncOpenAI clients are created.  Safe because
   cached clients are explicitly cleaned via _force_close_async_httpx,
   and uncached clients' TCP connections are cleaned by the OS on exit.

2. Custom asyncio exception handler: Installed on prompt_toolkit's event
   loop to silently suppress 'Event loop is closed' RuntimeError.
   Defense-in-depth for SDK upgrades that might change the class name.

3. cleanup_stale_async_clients(): Called after each agent turn (when the
   agent thread joins) to proactively evict cache entries whose event
   loop is closed, preventing stale clients from accumulating.

1519c4d477 fix(session): add /resume CLI handler, session log truncation guard, reopen_session API (#3315)
Three improvements salvaged from PR #3225 by Mibayy:

1. Add /resume slash command handler in CLI process_command(). The
   command was registered in the commands registry but had no handler,
   so typing /resume produced 'Unknown command'. The handler resolves
   by title or session ID, ends the current session cleanly, loads
   conversation history from SQLite, re-opens the target session, and
   syncs the AIAgent instance. Follows the same pattern as new_session().

2. Add truncation guard in _save_session_log(). When resuming a session
   whose messages weren't fully written to SQLite, the agent starts with
   partial history and the first save would overwrite the full JSON log
   on disk. The guard reads the existing file and skips the write if it
   already has more messages than the current batch.

3. Add reopen_session() method to SessionDB. Proper API for clearing
   ended_at/end_reason instead of reaching into _conn directly.

Note: Bug 1 from the original PR (INSERT OR IGNORE + _session_db = None)
is already fixed on main — skipped as redundant.

Closes #3123.
