From 1727b74161c34d5304ca51fa72854404ca8f5ed3 Mon Sep 17 00:00:00 2001 From: Illia Polosukhin Date: Fri, 10 Apr 2026 00:32:21 +0900 Subject: [PATCH 01/34] fix(workspace): collapse reindex delete+insert into one transaction to close TOCTOU race MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two concurrent reindexers for the same document could both DELETE the existing chunks, then both try to INSERT chunk_index 0, hitting the UNIQUE (document_id, chunk_index) constraint and failing with "database is locked" or constraint violation. The delete and inserts were separate libsql transactions with async points between them. Add `WorkspaceStore::replace_chunks(document_id, &[ChunkWrite])` that runs DELETE + N INSERTs inside a single BEGIN IMMEDIATE transaction (not the default DEFERRED — DEFERRED bypasses busy_timeout on the first write contention). The libsql impl, postgres impl, and the in-memory storage variant all go through the new method, and `Workspace::reindex_document` builds the `ChunkWrite` Vec (with embeddings) up front so nothing async happens between the delete and the insert loop. Regression test in `workspace::versioning_tests` spawns 4 concurrent writers against the same document on a multi-thread runtime and asserts last-writer-wins without UNIQUE collisions.

Two failure modes: 1. Display: users saw "google_oauth_token" in the auth-required prompt instead of the friendly extension name "google-drive-tool". 2. Routing: `submit_auth_token` expects an *extension* name and walks the extension's capabilities file to find the actual secret. Passing `google_oauth_token` directly fails closed with "Extension not installed: google_oauth_token", trapping the user in a re-auth loop on every paste. `bridge/router.rs` now resolves the actual extension via `tools.provider_extension_for_tool(action_name)` for both the gate display path and the `submit_auth_token` call. Built-in tools, HTTP, and skill credentials still fall back to the credential name (the existing behaviour for those callers). `extensions/manager.rs` fixes three more auth-readiness traps surfaced by the v2 Drive trace: - All capabilities lookups (`auth_wasm_tool`, channel activate, setup schema, configure, explicit secret query, upgrader) now go through `load_tool_capabilities` / `load_channel_capabilities` so a tool installed under the legacy hyphen filename (`google-drive-tool.capabilities.json`) is still resolved when looked up by canonical underscore name. The pre-v0.23 layout silently reported `no_auth_required` and bypassed the gate entirely. - `activate_wasm_tool` now uses `existing_extension_file_path` for both the `.wasm` and `.capabilities.json` lookups so the legacy hyphen filename is resolved here as well. Without this, the upstream `determine_installed_kind` happily reported the extension as installed via its own alias check, but `activate_wasm_tool` then failed with `NotInstalled` — the readiness probe fell back to "treat as ready" and the agent ended up calling a tool that couldn't activate, hit a 401/403, and looped trying to recover. - `configure()` post-activation OAuth cleanup now skips deletion when the caller is *also* providing a fresh credential in the same `secrets` map. The previous behaviour wrote the user's pasted token then immediately deleted it (along with `_scopes` / `_refresh_token` siblings), causing the resume to hit the wrapper with `token_exists=false` and re-fire the gate forever. Explicit Reconfigure (empty secrets map) still wipes the records to kick off a fresh OAuth dance. `config/mod.rs` test config now seeds a deterministic 32-byte master key so replay-mode tests that touch credentials get a working secrets store out of the box without each test having to build its own. Three regression tests in `extensions::manager::tests`: - `test_activate_wasm_tool_finds_legacy_hyphen_alias` - `test_auth_wasm_tool_finds_legacy_hyphen_alias` - `test_configure_preserves_oauth_token_when_caller_provides_it` - `test_configure_clears_oauth_token_for_reconfigure_flow` Co-Authored-By: Claude Opus 4.6 (1M context) --- src/bridge/router.rs | 153 +++++++++-- src/config/mod.rs | 15 +- src/extensions/manager.rs | 543 +++++++++++++++++++++++++++++++++----- 3 files changed, 613 insertions(+), 98 deletions(-) diff --git a/src/bridge/router.rs b/src/bridge/router.rs index 1a38aefee6f..fb603494fe3 100644 --- a/src/bridge/router.rs +++ b/src/bridge/router.rs @@ -51,7 +51,41 @@ fn gate_display_parameters(pending: &PendingGate) -> serde_json::Value { .unwrap_or_else(|| pending.parameters.clone()) } -async fn send_pending_gate_status(agent: &Agent, message: &IncomingMessage, pending: &PendingGate) { +/// Resolve the user-facing name to use when surfacing an authentication +/// gate to a channel.

The runtime converges on snake_case identifiers per `ToolRegistry::resolve_name`, and LLMs (Codex / GPT-5 in particular) silently normalize tool names to valid Python identifiers by converting dashes to underscores. The old code built the registry key as `format!("{server}_{tool}")` and preserved any dashes from the original tool name, so the registry got `notion_notion-search` while the LLM emitted `notion_notion_search` — direct lookup missed and the legacy alias fallback (which only goes underscores → dashes) couldn't reconstruct the mixed-separator form either, leaving every Notion MCP tool unreachable. Add `mcp_tool_id(server, tool)` in `tools/mcp/client.rs` that does `format!(...).replace('-', "_")`, re-export it from `tools/mcp/mod.rs`, and use it in: - `McpClient::create_tools` — the prefixed_name on every wrapped MCP tool now agrees with what the LLM will emit - `ExtensionManager::activate_mcp` — `tool_names` is now sourced from `tool_impls.iter().map(|t| t.name())` instead of being independently rebuilt from the raw McpTool list, eliminating drift between registered names and reported names - `ExtensionManager::latent_actions_for_mcp_server` — latent provider actions surfaced before activation use the same canonical form The original (possibly hyphenated) `t.name` is still preserved on the wrapper's inner `McpTool` and used verbatim when forwarding the `tools/call` request to the MCP server, so MCP protocol compatibility is unchanged — the canonicalization is internal-only. 5 regression tests in `tools::mcp::client::tests`: - `test_mcp_tool_id_canonicalizes_dashed_tool_name` - `test_mcp_tool_id_canonicalizes_dashed_server_name` - `test_mcp_tool_id_passthrough_for_already_canonical_names` - `test_create_tools_canonicalizes_dashed_mcp_tool_names` (drives `create_tools` end-to-end via MockTransport) - `test_create_tools_round_trips_through_registry_resolve_name` (caller-level test per `.claude/rules/testing.md` — registers the wrapped tools in a real `ToolRegistry` and asserts that `resolve_name("notion_notion_search")` returns the registered tool via the direct HashMap path, not via the legacy alias fallback) Co-Authored-By: Claude Opus 4.6 (1M context) --- src/extensions/manager.rs | 12 ++- src/tools/mcp/client.rs | 209 +++++++++++++++++++++++++++++++++++++- src/tools/mcp/mod.rs | 1 + 3 files changed, 216 insertions(+), 6 deletions(-) diff --git a/src/extensions/manager.rs b/src/extensions/manager.rs index 15f513aad8b..65649432f8b 100644 --- a/src/extensions/manager.rs +++ b/src/extensions/manager.rs @@ -5184,10 +5184,12 @@ impl ExtensionManager { .await .map_err(|e| ExtensionError::ActivationFailed(e.to_string()))?; - let tool_names: Vec = mcp_tools - .iter() - .map(|t| format!("{}_{}", name, t.name)) - .collect(); + // Source the reported names from the wrapper itself, not from the + // raw McpTool list.

The GitHub Copilot MCP's `github` tool uses top-level `oneOf` for action dispatch, so the agent was 400-ing the moment it tried to enumerate tools. `normalize_schema_strict` (already shared between the OpenAI Codex provider and `RigAdapter::convert_tools`) now short-circuits when it sees a forbidden top-level construct, replacing `parameters` with a permissive object envelope (`{type: "object", properties: {}, additionalProperties: true, required: []}`) and appending the original schema to the tool description as advisory text (truncated on a char boundary at 1500 bytes). The MCP server still validates the actual shape on its end, so the tool keeps working — we just lose API-level schema enforcement and the LLM has to read variant structure from the description. The function signature changes to take `&mut String` for the description (to append the hint). Both call sites (`openai_codex_provider::convert_tool_definition` and `rig_adapter::convert_tools`) pass an owned clone through. This is slightly lossy for Anthropic users on tools with top-level unions (Claude could have handled the union natively), but keeping a single normalizer for all rig-based providers is simpler than threading per-provider flags through the adapter, and the description hint preserves the variant info Claude needs. 2. **Python ↔ Rust `action_calls` field-name mismatch.** The Python orchestrator (`default.py`) appends assistant messages with `action_calls=calls` where each call is shaped `{name, call_id, params}` (the friendly Python names produced by `orchestrator.rs:handle_llm_complete`). The reverse parser `json_to_thread_messages` tried to deserialize via `serde_json::from_value::>`, which expects the canonical Rust field names `{action_name, id, parameters}`. The deserialize fails, but `.ok()` swallows the error and the assistant message comes back with `action_calls = None`. Every subsequent tool result then looks orphaned to `sanitize_tool_messages` and gets rewritten as a user message, losing the model's ability to reason about prior tool calls. Introduce a private `PythonActionCall` interchange struct as the single source of truth for the field naming convention, with bidirectional `From` conversions. Both call sites (Rust → Python serialization + Python → Rust deserialization) now go through `action_calls_to_python_json` / `python_json_to_action_calls`, so any future field addition only needs to touch one struct definition. `ActionCall` itself is unchanged — adding `#[serde(rename = ...)]` would have invalidated every persisted Step record and ThreadEvent. 11 regression tests: - `rig_adapter::tests::test_normalize_schema_strict_*` (6 tests) covering pass-through, top-level oneOf flatten, anyOf/allOf/enum/not flatten, non-object replacement, nested-oneOf preservation, and char-boundary truncation - `rig_adapter::tests::test_convert_tools_handles_top_level_oneof_dispatcher` (caller-level test driving `convert_tools` end to end) - `openai_codex_provider::tests::test_convert_tool_definition_handles_top_level_oneof_dispatcher` (caller-level test driving the codex provider path) - `executor::orchestrator::tests::python_action_call_round_trips_through_serde` - `executor::orchestrator::tests::action_calls_to_python_json_uses_python_field_names` - `executor::orchestrator::tests::python_json_to_action_calls_parses_python_field_names` - `executor::orchestrator::tests::python_json_to_action_calls_rejects_canonical_field_names` (guards against silent shape drift) - `executor::orchestrator::tests::json_to_thread_messages_preserves_action_calls_from_python_orchestrator` (caller-level test feeding the literal JSON shape `default.py` produces, asserting the assistant message's `action_calls` survive the round-trip with matching call_ids) Co-Authored-By: Claude Opus 4.6 (1M context) --- .../src/executor/orchestrator.rs | 243 +++++++++++- src/llm/CLAUDE.md | 2 +- src/llm/openai_codex_provider.rs | 76 +++- src/llm/rig_adapter.rs | 345 +++++++++++++++++- 4 files changed, 634 insertions(+), 32 deletions(-) diff --git a/crates/ironclaw_engine/src/executor/orchestrator.rs b/crates/ironclaw_engine/src/executor/orchestrator.rs index 1ba91bf1920..9b50536eb0d 100644 --- a/crates/ironclaw_engine/src/executor/orchestrator.rs +++ b/crates/ironclaw_engine/src/executor/orchestrator.rs @@ -42,7 +42,7 @@ use crate::types::event::{EventKind, ThreadEvent, summarize_params}; use crate::types::message::ThreadMessage; use crate::types::project::ProjectId; use crate::types::shared_owner_id; -use crate::types::step::{StepId, TokenUsage}; +use crate::types::step::{ActionCall, StepId, TokenUsage}; use crate::types::thread::{ActiveSkillProvenance, Thread, ThreadState}; use ironclaw_common::ValidTimezone; @@ -652,16 +652,9 @@ async fn handle_llm_complete( serde_json::json!({"type": "code", "code": code, "usage": usage}) } LlmResponse::ActionCalls { calls, content } => { - let calls_json: Vec = calls - .iter() - .map(|c| { - serde_json::json!({ - "name": c.action_name, - "call_id": c.id, - "params": c.parameters, - }) - }) - .collect(); + // Single source of truth for the Python interchange + // shape — must round-trip via `python_json_to_action_calls`. + let calls_json = action_calls_to_python_json(&calls); serde_json::json!({ "type": "actions", "content": content, @@ -2099,6 +2092,73 @@ fn build_orchestrator_inputs( (names, values) } +/// JSON shape used to interchange `ActionCall`s with the Python orchestrator. +/// +/// This is the *single* place that defines the field naming convention used +/// across the Python boundary.

Two phases: Phase A: delete the developer's real `google_oauth_token` (and the refresh token) from the test rig's libsql DB while keeping the `_scopes` companion record so `auth_wasm_tool`'s scope expansion check doesn't fire on the re-store. Send a Drive search prompt and assert the agent emits `StatusUpdate::AuthRequired` within one iteration. The expected path: 1. agent calls `google-drive-tool { action: "list_files" }` 2. wrapper's `resolve_host_credentials` reports `missing_required = ["google_oauth_token"]` 3. wrapper fails closed with the "requires credentials that are not configured" message 4. effect adapter's post-flight branch fires `auth::postflight::detect_post_call_auth_failure` 5. matcher hits the `requires credentials + not configured` pair (commit cd8b68de) 6. detector calls `ensure_extension_ready(.., ExplicitAuth)` → `EnsureReadyOutcome::NeedsAuth` 7. `EngineError::GatePaused { resume_kind: Authentication }` bubbles to the orchestrator 8. router stores it in `pending_gates` and emits `StatusUpdate::AuthRequired` Phase B: re-insert the captured token via `secrets_store()`, send the synthetic value as a follow-up message. The v2 router treats the next user message after an auth gate as `GateResolution::CredentialProvided`, which calls `submit_auth_token` (idempotent overwrite of what we just inserted) then `execute_pending_gate_action` → `execute_resolved_pending_action`, and the original Drive call replays. The test asserts the resume ran (additional tool activity + a follow-up response). Live-tier only (`#[ignore]`); skipped outside `IRONCLAW_LIVE_TEST=1`. The test deliberately does NOT commit a recorded trace fixture: any trace would inevitably capture the bearer token, real Drive file metadata, and HTTP headers — all PII that's hard to scrub safely. Hermetic regression coverage for the underlying alias-aware capabilities bug lives in `test_auth_wasm_tool_finds_legacy_hyphen_alias`. Supporting harness changes: - `LiveTestHarnessBuilder::with_no_trace_recording()` — opt-out flag for tests that touch real credentials. Live mode still runs against the real LLM but no fixture is committed; replay mode builds a stub harness so the test can detect the mode and skip gracefully without panicking on a missing fixture. - `LiveTestHarness::finish_turns(&[(user_input, responses)])` — multi-turn variant of `finish` for tests that span an auth-gate round-trip (prompt → AuthRequired → token → resume). The session log renders all turns in order so a reader can follow the full conversation, not just the first prompt. Status events are still rendered once at the top because the rig doesn't tag them with a turn boundary. - Session log formatter now renders `StatusUpdate::AuthRequired` and `StatusUpdate::AuthCompleted` so the gate is visible in the log. - `TestRig::secrets_store()` and `TestRig::owner_id()` accessors so live tests can manipulate credentials directly under the same scope the agent loop uses.

That's correct for top-level `oneOf` and `anyOf`, but actively misleading for the other forbidden constructs: - `allOf` — the LLM should pass fields from ALL variants combined, not pick one - `enum` — the LLM should pass one of the listed literal values, not "fields" - `not` — the LLM should pass any object that does NOT match the constraint Extract `FORBIDDEN_TOP_LEVEL` to a module-level constant (now shared between `needs_top_level_flatten` and a new `detect_forbidden_top_level` helper) and add `schema_flatten_hint_intro(detected)` which branches on the actual keyword that triggered the flatten and returns a precise intro string. Falls back to a "free-form object" message when the schema wasn't an object at all (no recognized forbidden keyword, just the wrong top-level type). New regression test `test_normalize_schema_strict_hint_is_keyword_aware` asserts that each of the 5 keywords produces a hint containing the expected discriminating phrase.

Two concurrent reindexers running under separate snapshots can both DELETE (each sees its own pre-delete state, neither sees the other's), then race to INSERT chunk_index 0 and hit the `UNIQUE (document_id, chunk_index)` constraint. Add `SELECT 1 FROM memory_documents WHERE id = $1 FOR UPDATE` at the top of the transaction. The `FOR UPDATE` row lock is per-document, ties to the existing parent row (FK already in place from `memory_chunks.document_id`), and is released automatically on commit/rollback. Concurrent reindexers for the same doc now serialize on the parent row and last-writer-wins cleanly. Picked `FOR UPDATE` over `pg_advisory_xact_lock` because it's the row-locking primitive PG operators expect when reading the code, and it doesn't introduce a hash function dependency for the lock key.

That works but it's lossy — the LLM can't do schema-based reasoning about which fields exist, and the description hint is truncated to 1500 bytes so deeply-nested schemas are unreadable. Add `merge_top_level_variant_properties` which walks the union variants, collects every property they declare, and returns a single map. The flatten envelope now uses that map instead of empty `{}`, so the LLM sees structured field hints. `additionalProperties: true` and `required: []` are preserved, so strict-mode validation stays disabled and the LLM is free to mix fields across variants — the upstream MCP server enforces the actual constraints on its end. First-write wins on conflicting types: if two variants declare the same field with different schemas, the first variant's schema is kept. The full original schema still goes into the description hint, so the ambiguous case is recoverable from there. Two new regression tests: - `test_normalize_schema_strict_merges_variant_properties` exercises a GitHub-Copilot-shaped tool with two variants that share a discriminator and asserts every field from every variant survives. - `test_normalize_schema_strict_merge_first_write_wins_on_conflict` pins the documented conflict-resolution behaviour.

The inline sites couldn't use the helper because they'd already destructured `credential_name` from the `ResumeKind` match and needed the result for `submit_auth_token`, not just display. Extract the core into `async fn resolve_extension_for_action(tools, action_name, credential_fallback) -> String`. Make `resolve_auth_gate_display_name` a thin wrapper that handles the non-Authentication ResumeKind variants. Both inline sites now call the helper directly with the destructured `credential_name`. The two inline-site comment blocks that explained the rationale are collapsed into shorter "see helper for full rationale" pointers since the doc on `resolve_extension_for_action` carries the full explanation now. Three sites collapse to one implementation. The auth display + routing logic now has a single source of truth.

The second `ToolRegistry::register` call silently shadows the first with no signal at all — operators debugging an unreachable tool would have zero breadcrumb to discover the collision. Add collision detection in `McpClient::create_tools` itself, where we still have both the original tool name and the normalized id. Build a `HashMap` while iterating, and emit a `tracing::warn!` when two distinct originals collide on the same id. The warn carries the normalized id, both colliding original names, and the server name, so an operator can immediately see which upstream tools to rename. Behaviour is unchanged — the second tool still wins on register, matching what the LLM would emit anyway since it normalizes both names to the same string. The collision detection is scoped to a single MCP server's tool list because cross-server collisions have different registry-key prefixes (`server_a_foo` vs `server_b_foo`) and can't actually shadow each other. This is the right level — `ToolRegistry::register` itself doesn't have access to the pre-normalization name and couldn't emit this signal even if we wanted it there. New regression test `test_create_tools_handles_post_normalization_collision` drives a MockTransport that lists `search-all` and `search_all`, asserts both wrappers are produced with the same `Tool::name()`, registers them in a real `ToolRegistry`, and asserts last-write-wins on shadow.

The Python orchestrator (`default.py`) accesses `c.get("name")` / `c.get("call_id")` / `c.get("params")` on each entry, so a `null` would crash with a Python `AttributeError` and lose the entire LLM step — and the fallback contradicts this PR's own stated goal of not silently swallowing errors. Replace with `filter_map` so a failed entry is dropped from the output rather than corrupting it. The warn log on the failure path is preserved (and now also includes `action_name` for easier correlation). Python's tool-result loop iterates `range(len(results))` against the same shortened call list so a missing entry is benign. Note: the failure path is essentially unreachable for the `PythonActionCall` shape (`String + String + Value` all infallible-to-serialize) but the contract should still be safe — the helper will be touched again when the Python interchange shape evolves and we don't want a future maintainer to discover this trap the hard way.

Tool params can carry user PII (search queries, file names, email content, conversation text), and the warn fires precisely when the Python ↔ Rust shape drifts — exactly the moment operators will be grepping logs and shipping output to log aggregators (Datadog, CloudWatch, Sentry). Add `summarize_action_calls_for_log` which builds a structural-only summary: array length and the keys of the first entry. The keys themselves are static field names (`name`, `call_id`, `params`), not user data. The shape summary is enough to debug a drift (operator can see whether the shape is roughly right and which fields are missing) without exposing any of the actual parameter contents. Edge cases handled: - empty array → "empty array" - non-array value (Python passed wrong shape) → "non-array value of type " via a small `json_value_type_name` helper - entries that aren't objects → "" rather than attempting to walk them Two regression tests: - `summarize_action_calls_for_log_does_not_leak_user_pii` builds an intentionally PII-laden value with salary spreadsheet queries, credentials, and "private message about layoffs" content, asserts none of the user-content strings appear in the summary, AND that even the upstream tool name doesn't leak (operator-level intent signal). - `summarize_action_calls_for_log_handles_edge_cases` pins the empty/string/object/null fallback paths.

Our PR already fixed the core issue (mcp_tool_id canonicalization + stricter non-identifier-char normalization), but #2227 adds valuable defense-in-depth and compatibility layers that we didn't cover: - `tools/mcp/factory.rs` — normalize `server.name` at the factory boundary (before any branch including the OAuth early-return). This ensures the secret name, session key, and tool prefix all use the same underscore-only form. Our PR normalized only at the tool-id level which left the server_name itself hyphenated in the session manager and token secret store. - `tools/mcp/client.rs` — normalize `new_with_name` so callers that pass a hyphenated server name get consistent behavior even when bypassing the factory. - `tools/mcp/config.rs` + `tools/mcp/auth.rs` — legacy token secret name fallback for pre-normalization tokens. When checking if an MCP server is authenticated, if the canonical (underscore) secret name doesn't exist, try the legacy (hyphenated) form. This prevents forcing re-auth on existing users who stored tokens under the old hyphenated server name before upgrade. - `tools/registry.rs` — bidirectional `resolve_key` helper that tries exact → hyphen→underscore → underscore→hyphen aliases in `get`, `has`, `unregister`, `resolve_name`, `get_resolved`, `provider_extension_for_tool`, and `tool_definitions_for_actions`. Defense-in-depth: even if a tool somehow ends up registered with a mixed-separator name (edge case, stale DB, manual insertion), the registry will still find it. 4 new regression tests cover both alias directions, get_resolved, and unregister via alias. - `tools/wasm/loader.rs` + `channels/wasm/loader.rs` — `load_from_dir` and `discover_*` functions normalize hyphenated filenames (file stem → replace('-', "_")). Dev tool install name changed from `{name}-tool` to `{name}_tool`. Conflict resolution: manager.rs (kept our version with comment), client.rs create_tools (kept our `mcp_tool_id` which is strictly better — handles ALL non-identifier chars, not just dashes), client.rs tests (kept our comprehensive MockTransport-based test suite, dropped #2227's simpler duplicate). All other hunks from #2227 applied cleanly.

A hyphenated server name like `my-server` produced a prefix `my-server_` that matched zero tools (they're all `my_server_*`), returning empty tool lists and failing to unregister on extension removal. Fix: use `crate::tools::mcp::mcp_tool_id(name, "")` as the prefix. This produces `my_server_` from `my-server`, matching the registered keys exactly. All 3 sites now use the same normalization as tool registration.

Changed the signature to accept `wasmtime::Error` directly. This is also more correct — accepting the native error type preserves type information that a lossy `.into()` conversion would strip, making the structured `Trap` downcast more reliable. 2. **String-matching fallback (Copilot, wrapper.rs:1107):** The doc claimed "falls back to string matching" but the implementation only did the structured downcast. Added a string-matching fallback that checks the full Display chain for "all fuel consumed", "out of fuel", "OutOfFuel", and "unreachable" when the downcast fails. This covers the case where component-model glue or host wrappers bury the Trap inside layers that `downcast_ref` can't see through. New regression test `trap_classification_fuel_via_string_fallback` exercises this path using a plain `wasmtime::Error::msg` wrapper. 3. **Stale doc comment (Copilot, test_rig.rs:1282):** Updated `secrets_store()` doc to reflect that most test rigs now have a working secrets store because `Config::for_testing()` generates a random master key per call. `None` only occurs with a config override that explicitly disables secrets.

The old match would false-positive on HTTP errors like "endpoint was unreachable" or "server unreachable: connection refused", replacing the real diagnostic chain with a generic message. 2. `rig_adapter.rs:326` — added `count_json_nodes` pre-check (cheap recursive walk, no alloc) before calling `serde_json::to_string`. A malicious MCP server with a many-MB schema would have triggered a proportional allocation even though we only keep 1500 bytes. Schemas over 5000 nodes skip serialization entirely and get a "(schema too large to inline)" placeholder instead. 3. `auth.rs:1202` — documented that the legacy token fallback intentionally uses bare `get_decrypted` (no refresh). The path is transitional: users re-auth once and get migrated to the canonical naming scheme. Wiring refresh through the legacy path adds complexity for a self-healing compat layer. 4. `rig_adapter.rs:171` — Anthropic lossiness was already documented in the `normalize_schema_strict` doc comment (lines 164-170). Reply-only; per-provider flag is a follow-up.

The root cause pattern: we're playing whack-a-mole with OpenAI's undocumented strict-mode rules, adding fixes one at a time when a new tool exposes a schema shape the normalizer doesn't handle. Each time, the fix is a runtime 400 in production that takes a PR cycle to fix. The structural fix: run validate_strict_schema as a debug-level post-check after normalization. If the normalizer missed something, the diagnostic appears in local logs immediately (before the schema even reaches the LLM provider), giving developers a local breadcrumb instead of a runtime 400 from OpenAI. The schema still goes through (the tool remains usable), and the LLM provider surfaces the 400 if OpenAI actually rejects it — but now the cause is instantly visible in `RUST_LOG=ironclaw::llm=debug` output. This also means that any future normalizer rule we add gets automatic regression coverage: if the normalizer introduces a bug that violates a rule the validator knows about, the debug log fires on every tool call in dev mode.

The flatten path in `normalize_schema_strict` short-circuited with `return schema`, skipping BOTH the recursive normalizer AND the post-normalization validator. The merged properties copied from union variants were raw — a `Vec` field like google_docs_tool's `requests` kept its bare `{"type": "array"}` without `items`, and OpenAI rejected it with "array schema items is not an object" on every tool-using call. Fix: the flatten path now normalizes each merged property individually via `normalize_schema_recursive(prop_schema)` before returning the envelope. The top-level envelope stays permissive (`additionalProperties: true`, `required: []`) so the LLM can mix fields across variants, but each property's internal schema gets the full treatment (array items, nested objects, etc.). The post-normalization validator also runs on both paths now (no early return before it). Regression test: `test_normalize_schema_strict_flatten_normalizes_merged_array_items` mimics the google_docs_tool shape (tagged enum with `oneOf`, one variant containing an items-less array) and asserts the merged `requests` property has `items` as an object after normalization. 2. `python_json_to_action_calls` warn log fired on every text-only assistant message with "invalid type: null, expected a sequence" because Python's `action_calls: null` (legitimate "no tool calls" signal) was passed to the parser. Added a `.filter(|v| !v.is_null())` before the parser call in `json_to_thread_messages` so null is treated the same as "key absent" — no parse attempt, no false alarm. The warn only fires for genuinely malformed data now.

The approach also missed the case a reviewer flagged: few-node schemas with multi-MB string values would pass the node check but still allocate proportionally during `serde_json::to_string`. Replace both the node counter and the `to_string` + truncate pattern with `serialize_json_capped(value, max_bytes)`: a `serde_json::to_writer` call through a `CappedWriter` that silently discards bytes past the budget. This bounds the actual heap allocation to `max_bytes` regardless of schema shape — many-node deep recursion AND multi-MB string values are both capped. The writer returns `Ok(data.len())` after the cap so serde_json thinks all bytes were consumed and continues (minimal remaining work since the output is being discarded). The output is guaranteed valid UTF-8 because serde_json only emits ASCII structural characters and JSON-escaped unicode. The `count_json_nodes` function and `MAX_SCHEMA_NODES` constant are removed — the capped serializer subsumes them entirely.

The mismatch surfaced as "missing field \`name\`" on every thread resume after a gate pause (approval, auth), orphaning all subsequent tool results. This is the SECOND code path (after `handle_llm_complete`) that feeds action_calls into the Python working transcript. Both must use the same shape — `action_calls_to_python_json` is the single source of truth. Triggered by: user approves `tool_upgrade` → thread resumes → bootstrap rebuilds context from `internal_messages` (which stores canonical `ActionCall`s from the DB) → Python reads `{action_name, id, parameters}` → echoes them back on next LLM call → `python_json_to_action_calls` fails → assistant message loses tool_call linkage → all tool results orphaned.

The existing round-trip test only covered the `__llm_complete__` path (within a single Python orchestrator run), not the bootstrap path (thread resume after gate pause). Anyone adding a THIRD serialization path in the future would have no test guardrail. Two new tests: 1. `bootstrap_context_action_calls_round_trip_through_python_interchange`: Builds a `ThreadMessage` with `action_calls` in canonical format (the shape stored in the DB), serializes through the EXACT pattern `build_orchestrator_inputs` uses, parses back through `json_to_thread_messages`, and asserts the calls survive. This is the test that would have caught the gate-resume bug on the first attempt. 2. `canonical_action_call_field_names_do_not_round_trip`: Negative test that verifies canonical names (`{action_name, id, parameters}`) are REJECTED by the parser. Documents the current contract: if this test ever passes, the `PythonActionCall` interchange type can be removed because the formats unified. Serves as a tripwire for anyone who adds `#[serde(rename)]` to `ActionCall` or changes the parser to accept both formats. Together these two tests cover every known serialization boundary into the Python transcript and make the failure mode instantly visible in `cargo test` rather than as a runtime warn log after a gate pause.

With 12 flattened tools loaded, this produced 12 debug log lines PER LLM CALL, drowning real signals. The flatten path's output is intentionally non-strict — running a strict-mode validator on it is semantically wrong. Move the validator behind the non-flatten branch and add an early `return schema` for the flatten path (after normalizing individual properties). The validator still catches issues on normal strict-mode schemas (the non-flatten path), which is where it has value.

New tests: 1. **test_realistic_wasm_schema_survives_normalize_flatten_pipeline** (rig_adapter.rs) — End-to-end test using the google_docs_tool's actual schema shape: tagged enum with 4 variants, one containing `requests: Vec` (bare array, no items), one with a nested object (text_style). Drives through normalize_schema_strict AND convert_tools. Asserts oneOf flattened, all variant properties merged, array items is object, nested objects get strict-mode. This single test would have caught BOTH production bugs (flatten path short-circuit + array items unreachable on flatten path). 2. **test_normalize_schema_strict_fixes_deeply_nested_array_items** (rig_adapter.rs) — 3-level nesting: object → array → object → array → object → array. Verifies the recursive normalizer walks the full depth and fixes every array items at every level. 3. **json_to_thread_messages_handles_null_action_calls_gracefully** + **handles_absent_action_calls** + **handles_empty_action_calls_array** (orchestrator.rs) — Three edge cases for the Python ↔ Rust message round-trip: null (was a false alarm), absent (baseline), and empty array (valid, produces Some(vec![])). The null case would have caught the "invalid type: null, expected a sequence" false alarm before it hit production. 4. **latent_provider_actions_normalize_hyphenated_server_names** (manager.rs) — Registers an MCP server with hyphenated name (`my-mcp-server`) and two tools (one with dashes, one without). Asserts latent action_names use all-underscore form (`my_mcp_server_search_all`) and the old hyphenated form doesn't survive. Exercises the mcp_tool_id normalization at the ExtensionManager layer. 5. **test_serialize_json_capped_boundary_conditions** + **test_serialize_json_capped_large_string_values** (rig_adapter.rs) — Size-capped serializer edge cases: under cap (full output), exactly at cap, over cap (truncated), zero cap (empty), and the multi-MB-string-in-few-nodes case the old node counter missed.

charset=UTF-8 Content-Transfer-Encoding: 8bit 1. **serialize_json_capped UTF-8 safety** (Copilot, rig_adapter.rs:399): serde_json v1 emits raw UTF-8 for non-ASCII chars (e.g. CJK in property descriptions), so byte-capped truncation can cut mid-codepoint. `String::from_utf8` now falls back to `e.valid_up_to()` to trim to the last complete codepoint instead of dropping the entire hint on a UTF-8 error. 2. **FOR UPDATE row count check** (Copilot x2, repository.rs:377): `SELECT 1 ... FOR UPDATE` returns 0 rows if the document doesn't exist, silently acquiring no lock. Now checks the row count and returns a clear `ChunkingFailed` error when it's 0. 3. **MCP config lookup alias-aware** (serrrfirat, factory.rs:40): `get_mcp_server` now tries exact name → hyphen alias (underscores→hyphens) → underscore alias (hyphens→underscores). After factory normalizes `server.name` to underscores, `provider_extension_for_tool` returns `my_server`, but the persisted config is keyed as `my-server`. Without alias lookup, `activate_mcp("my_server")` failed with `ServerNotFound`. 4. **Legacy token request-time fallback** (serrrfirat, auth.rs:1208): `get_access_token` now falls back to the legacy (pre-normalization) secret name when the canonical name returns no token. Without this, `is_authenticated` reported true (it has its own fallback) but the actual MCP request sent no Authorization header — the server appeared ready but tool execution 401'd until re-auth. 5. **Stale reindex guard** (serrrfirat, workspace/mod.rs:2181): `reindex_document_with_metadata` now captures the content hash at read time and re-checks it after computing embeddings. If another writer updated the document content during the embedding window, the reindexer skips chunk replacement — the other writer's reindex call will produce correct chunks for the new content. This closes the content-vs-chunks skew where writer B wins the document UPDATE but writer A wins the later replace_chunks transaction. 6. **Log summary PII concern** (Copilot, orchestrator.rs:2020): false positive — the keys logged are JSON Schema property names from the PythonActionCall interchange dict, not user tool parameters.

The path comparison in `restore_latest` mismatched, returning "No file history found" even though the snapshot existed. Fix: canonicalize paths consistently at both the storage boundary (`snapshot()`) and the lookup boundary (`latest_snapshot_for()`, `snapshots_for()`, `restore_latest()`). A shared `canonical()` helper handles the non-existent-file case (write_file's "new file" path) by canonicalizing the parent directory and joining the filename — the parent always exists even when the file itself doesn't yet. This was a pre-existing staging failure from PR #2025 that affected all macOS developers.

Also replaces `.expect()` in `rig_adapter.rs` with `from_utf8_unchecked` (sound per `valid_up_to` invariant) to fix the no-panics CI check.
