-## tools/registry.py (dependency root, 810 lines)
-
-### invalid-parameter-default (FIXED)
-three params in `ToolEntry.register()` were annotated as bare `Callable` / `list`
-but defaulted to `None`. this is the #1 pattern ty flags across the whole codebase
-(~423 occurrences). the fix is always the same: add `| None` to the annotation.
-
-```python
-# BEFORE
-check_fn: Callable = None,
-requires_env: list = None,
-dynamic_schema_overrides: Callable = None,
-
-# AFTER
-check_fn: Callable | None = None,
-requires_env: list | None = None,
-dynamic_schema_overrides: Callable | None = None,
-```
-
-this is the single highest-leverage fix across the codebase. each one of these
-cascades: when ty sees `None` as a possible value, every downstream `d["key"]`,
-`d.get(...)`, `d.pop()` on that variable becomes an `unresolved-attribute` or
-`not-subscriptable` or `invalid-argument-type` error. fixing the parameter
-default upstream makes all those downstream errors vanish.
-
-### antipattern: ToolEntry.__init__ has zero annotations
-
-```python
-def __init__(self, name, toolset, schema, handler, check_fn,
-             requires_env, is_async, description, emoji,
-             max_result_size_chars=None, dynamic_schema_overrides=None):
-```
-
-this is a core data class (every tool in the system passes through it) but has
-no type annotations on any parameter. `__slots__` is used so the shape is
-well-defined — adding annotations would be straightforward and high-value.
-ty can't infer much here because everything comes through as `Unknown`.
-
-not fixed yet — would benefit from a proper pass:
-```python
-def __init__(
-    self,
-    name: str,
-    toolset: str,
-    schema: dict,
-    handler: Callable,
-    check_fn: Callable | None,
-    requires_env: list[str],
-    is_async: bool,
-    description: str,
-    emoji: str,
-    max_result_size_chars: int | float | None = None,
-    dynamic_schema_overrides: Callable | None = None,
-):
-```
-
-### antipattern: tool_error / tool_result helpers lack annotations
-
-```python
-def tool_error(message, **extra) -> str:  # message: str, **extra: Any
-def tool_result(data=None, **kwargs) -> str:  # data: dict | None, **kwargs: Any
-```
-
-these are the canonical serialization helpers used by hundreds of tool handlers.
-low-effort to annotate, high-value since they're the return path for everything.
-
-### clean pattern: _check_fn_cached TTL + grace window
-
-this is well-done code. the TTL cache with transient-failure suppression is
-a correct implementation of a flaky-external-check absorption pattern. the
-docstrings explain WHY (issue #21658 / #5304 — flaky docker probes stripping
-tools mid-session). nothing to change here, just noting it as a positive
-example of defensive caching done right.
-
-### clean pattern: _snapshot_state() for thread safety
-
-using `_lock` + snapshot copies for reads is the right pattern for a registry
-that can be mutated by MCP dynamic refresh while other threads read. the
-generation counter for cache invalidation is also clean.
-
-### observation: `from typing import` vs PEP 604 `X | None`
-
-the file imports `Optional`, `Callable`, `Dict`, `List`, `Set` from `typing`
-but also uses `int | float | None` (PEP 604) in the same signatures. the
-codebase targets python >=3.11 so PEP 604 is always available. there's a
-mix of `Optional[X]` and `X | None` styles across files — not a bug, but
-worth standardizing on `X | None` (PEP 604) as we type-sweep since it's
-shorter and the modern idiom.
-
----
-
-## agent/agent_init.py + run_agent.py (AIAgent constructor, 60+ params)
-
-### invalid-parameter-default (FIXED — 31 + 54 params)
-same pattern as registry.py but at massive scale. the AIAgent.__init__ in
-`agent_init.py` and the class `AIAgent.__init__` in `run_agent.py` each take
-~60 params, nearly all defaulting to None but annotated as bare `str`, `list`,
-`dict`, `int`, etc.
-
-### antipattern: lowercase `callable` used as a type annotation
-
-**this is a real runtime bug, not just a type error.** 14 callback params in
-both `agent_init.py` and `run_agent.py` were annotated as `callable` (the
-builtin *function*) instead of `Callable` (from `typing`).
-
-```python
-# BEFORE — runtime crash if you try `X | None`
-tool_progress_callback: callable = None,  # callable is the builtin function
-
-# AFTER
-tool_progress_callback: Callable | None = None,  # Callable is the type
-```
-
-when the automated sweep script added `| None` to these, it produced
-`callable | None` which crashes at *import time* with:
-```
-TypeError: unsupported operand type(s) for |: 'builtin_function_or_method' and 'NoneType'
-```
-
-this was lurking silently as long as nobody tried to make the annotation
-nullable — the `callable` builtin is truthy so `callable = None` didn't
-crash, it just stored a nonsensical annotation. the fix is `Callable` (capital C).
-
-also spotted in `agent/transports/chat_completions.py` in docstring-like
-comments (lines 290, 314-315) — not executable code but worth standardizing.
-
-### antipattern: string forward-ref with `| None` doesn't work
-
-```python
-# WRONG — crashes at class-def time
-iteration_budget: "IterationBudget" | None = None,
-# TypeError: unsupported operand type(s) for |: 'str' and 'NoneType'
-
-# RIGHT — wrap the whole thing in Optional
-iteration_budget: Optional["IterationBudget"] = None,
-```
-
-when a type is a forward reference (string-quoted because it's not yet defined),
-you CANNOT use PEP 604 `| None` on it directly — the `|` operator tries to
-OR a `str` with `NoneType` and crashes. must use `Optional["ForwardRef"]`.
-
-this affected both `agent_init.py` and `run_agent.py`.

----
-
-## summary of the invalid-parameter-default sweep
-
-total params fixed: ~250 across ~25 core files
-the pattern is always identical: `param: Type = None` → `param: Type | None = None`
-
-two runtime-breaking gotchas found during the sweep:
-1. lowercase `callable` (builtin function) → must be `Callable` (typing)
-2. string forward-refs can't use `| None` → must use `Optional["Ref"]`

-## run_agent.py — unresolved-attribute analysis (190 errors)
-
-### category 1: "Self@<method>" — init_agent() cross-module init (186/190)
-
-these are ALL the same root cause: `AIAgent.__init__` in `run_agent.py` is a
-thin forwarder that calls `init_agent(self, ...)` from `agent/agent_init.py`.
-that function sets `self.model`, `self.provider`, `self.session_id`, etc. on
-the instance — but ty can't see across the module boundary that these
-attributes are being set. so every method that accesses `self.model`,
-`self.provider`, etc. gets flagged.
-
-**these are NOT bugs.** the attributes are correctly set at runtime by
-`init_agent()`. this is a ty limitation — it can't track attribute assignments
-made in a function defined in a different module that receives `self` as a
-regular parameter (not as a method on the class).
-
-example:
-```python
-# run_agent.py
-class AIAgent:
-    def __init__(self, model: str = "", ...):
-        from agent.agent_init import init_agent
-        init_agent(self, model=model, ...)  # sets self.model, self.provider, etc.
-
-    def _resolved_api_call_timeout(self):
-        return self.provider  # ty: "Self@_resolved_api_call_timeout has no attribute provider"
-```
-
-**fix approach:** this is the single biggest cluster of ty errors in the
-codebase (186 in run_agent.py alone, plus similar in other files). the cleanest
-fix would be to declare the attributes as class-level annotations in the
-`AIAgent` class body so ty knows they exist:
-
-```python
-class AIAgent:
-    # Instance attributes — set by init_agent() in agent/agent_init.py
-    model: str
-    provider: str | None
-    session_id: str | None
-    # ... etc
-```
-
-this is a one-time declaration that would clear ~186 errors instantly. it's
-also good documentation — currently there's no single place that lists all
-instance attributes; they're scattered across the 60-param init_agent() body.
-
-### category 2: object.function — duck-typed tool_calls access (2 errors)
-
-line 1968: `tc.function.name` and `tc.function.arguments` on objects typed as
-`object`. this is because `msg.tool_calls` is checked via `hasattr` +
-`isinstance(list)` but the list elements are `object` to ty.
-
-```python
-if hasattr(msg, "tool_calls") and isinstance(msg.tool_calls, list) and msg.tool_calls:
-    tool_calls_data = [
-        {"name": tc.function.name, "arguments": tc.function.arguments}
-        for tc in msg.tool_calls
-    ]
-```
-
-**not a bug** — this is duck-typed access to OpenAI SDK objects. the `hasattr`
-guard makes it safe at runtime. ty just can't infer the element type of a
-list accessed via `hasattr`. could be fixed with a `type: ignore` or by
-narrowing `msg` to a proper type.
-
-### category 3: ~AlwaysFalsy.on_session_end — duck-typed context_compressor (2 errors)
-
-lines 3416, 3441: `self.context_compressor.on_session_end(...)` after a
-`hasattr(self, "context_compressor") and self.context_compressor` guard.
-
-```python
-if hasattr(self, "context_compressor") and self.context_compressor:
-    self.context_compressor.on_session_end(self.session_id or "", messages or [])
-```
-
-ty narrows `self.context_compressor` to `~AlwaysFalsy` (the truthy branch of
-the `and`) but doesn't know it has `on_session_end`. **not a bug** — the
-`hasattr` guard makes this safe. again a type-system limitation with
-duck-typed access.
-
-### verdict for run_agent.py: 0 real bugs, 190 type-system limitations
-
-all 190 are ty being unable to track either cross-module attribute init
-(186) or duck-typed hasattr-guarded access (4). no logic bugs found.
-
-### remaining 6 unresolved-attribute (post class-level annotation fix)
-
-1. **line 2162** (`object.function` ×2): duck-typed access to OpenAI SDK
-   `ChatCompletionMessageToolCall` objects. `hasattr` guard makes it safe.
-   ty can't infer the list element type through `hasattr`. not a bug.
-
-2. **lines 3586-3587** (`iteration_budget.used` / `.max_total`): `iteration_budget`
-   is `Optional[IterationBudget]` but `init_agent` always sets it to a non-None
-   value (`iteration_budget or IterationBudget(max_iterations)`). the annotation
-   says `| None` but the code guarantees non-None at runtime. not a bug — but
-   the annotation could be tightened to just `IterationBudget` (without Optional).
-
-3. **lines 4677 + 4799** (`_anthropic_client.close()`): `_anthropic_client` is
-   `Any | None` — could be None if the anthropic path was never taken. but both
-   call sites are wrapped in `try/except Exception: pass`, so even if it IS None,
-   the AttributeError is caught. safe.

-## plugins/platforms/discord/adapter.py — unresolved-attribute analysis (269 errors)
-
-### root cause: ty resolving the wrong Python environment
-
-the `.venv` directory (created by `uv run` earlier) contained Python 3.13 with
-NO dependencies installed. ty auto-discovers `.venv` and uses it for module
-resolution — so it couldn't find `discord.py`, `aiohttp`, etc., producing 254
-`Module 'discord' has no member X` errors.
-
-the actual dependencies are installed in the nix develop environment
-(Python 3.12, all deps in site-packages). removing the empty `.venv` made ty
-fall back to the system/nix python, resolving all 254 import errors instantly.
-
-**fix:** `rm -rf .venv` (it was a stray artifact, not a real venv).
-also set `python-version = "3.12"` in `[tool.ty.environment]` to match the
-nix env, with a comment explaining why.
-
-**impact:** 4,422 → 3,385 diagnostics (−1,037) from this single fix.
-
-### remaining 122 discord errors (post-fix)
-
-after ty could resolve discord.py:
-- 17 `not defined on None` — `self._client` (Optional[commands.Bot]) accessed
-  before ty can prove it's non-None. all are in event handlers called after
-  the bot is ready. not bugs, but could benefit from `assert self._client is not None`
-  guards for type narrowing.
-- ~100 remaining are real type-checking errors from ty now being able to
-  see discord.py's actual types (mismatched args, wrong attribute access, etc.)
-  these need individual triage.

-"""Exit watchdog: arm on shutdown *intent* (signal), never at chat startup.

-Regression coverage for the #65998 class: a ``hermes --tui`` process whose
-main thread wedges before ``app.run()`` returns never executes the ``finally``
-that calls ``_run_cleanup`` — the only place the exit watchdog used to be
-armed — so a "dead" CLI lingered indefinitely (observed ~47 min at 4% CPU).
-
-The fix arms the backstop from the SIGTERM/SIGHUP handlers via
-``_arm_exit_watchdog_on_shutdown_signal()``. Arming at *startup* (the
-rejected #65998 approach) is specifically forbidden: the watchdog thread
-calls ``os._exit(0)`` unconditionally after its sleep, so a startup-armed
-timer hard-kills every session that outlives the timeout.

-The fix: ``_execute_write`` detects the malformed-image class, performs a
-one-shot in-place FTS rebuild (FTS5 ``'rebuild'`` command — index rewritten
-from canonical rows, no messages touched), and retries the failed write.
