…ion re-tune, injection budget, config-knob wiring

Quick-win slice from the July 2026 memory audit
(docs/research/memory-audit-2026-07.md):

- Curation LLM tier (measured DEAD in production — 0 successful decisions
  ever): MaxOutputTokens 512→1500 and per-call reasoning suppression
  (chat_template_kwargs.enable_thinking=false + ollama think=false); new
  'Memory Curation LLM' doctor check scans daemon logs and warns on a dead
  or >20%-failing tier.
- Balanced curation prompt (measured Pareto win, May 2026 decider eval):
  'same underlying FACT?' framing, dated observations append-only, kills the
  date/price/status UPDATE-overwrite guidance; content previews 200→700 chars.
- Recall precision re-tune: AnchorMatchWeight 8→2, SoftScopeWeight 3.5→0
  (measured junk-injection vectors), DurableFact RecallRank 120→480, floor
  10→14 — durable facts now need two independent lexical matches (or one +
  facet); zero-injection turns are intended behavior (65% of real queries
  had nothing relevant to inject).
- Injection char budget: SessionTuning.MaxRecallInjectedChars (default 2000),
  whole items dropped in rank order, first-ranked always admitted;
  memory_retrieval_final logs injectedChars + droppedByBudget. Schema synced.
- Wired the dead MemoryConfig knobs: RecallTimeoutMs and AutoRecallMaxItems
  now actually feed SessionRecallManager (were hardcoded 300ms/3).
- Retroactive netclaw-dev#1225 data repair in SQLiteMemoryStore.InitializeAsync:
  legacy compaction-boundary rows at recall_mode=searchable (still in the
  automatic pool — measured top polluter) move to manual, idempotently.
- Truth-ups: MemoryIndexContextLayer no longer claims durable_fact-only
  recall; netclaw-memory skill 1.7.0 documents selective recall and that
  zero-injection turns are normal.
- Tests: scenario P09 re-pinned as the paraphrase-gap case (expected empty
  under lexical recall; flips back with hybrid recall), evidence-class
  plumbing test pins policy vs plumbing explicitly, new tests for the char
  budget and the compaction repair. 4,971 tests green; slopwatch clean.

… instead of raw wire fields

The curation-actor reasoning suppression shipped earlier in this PR set raw
provider-dialect fields (chat_template_kwargs.enable_thinking, think) directly
on ChatOptions.AdditionalProperties — a provider-agnostic seam. That was only
correct for the pass-through OpenAiCompatibleChatClient, which forwards
AdditionalProperties verbatim as top-level request JSON for vLLM/llama.cpp/
SGLang. For every other provider the raw keys were wrong in one of two ways:

- Verified by decompiling Microsoft.Extensions.AI.OpenAI 10.6.0
  (OpenAIChatClient.ToOpenAIOptions, OpenAIResponsesChatClient) and
  Anthropic.SDK 12.35.1 (AnthropicChatClient.GetMessageCreateParams): neither
  adapter ever iterates ChatOptions.AdditionalProperties onto the request
  body — both only special-case a "strict" flag for JSON-schema response
  formats. So on OpenAI/Copilot/OpenRouter/VeniceAI/Anthropic the keys were
  silently inert (dropped, not 400s) — dead weight masquerading as a fix.
- Any future adapter that DOES forward extras (or a RawRepresentationFactory
  path) would push unknown top-level params at strict APIs, which reject them
  with 400.

This change replaces the raw fields with a provider-mapped intent key:

- NetclawChatOptionKeys.SuppressReasoning ("netclaw:suppress-reasoning") in
  Netclaw.Configuration — call sites express intent, never wire dialect.
- ILlmProviderPlugin.SuppressionDialect (default None — a genuine domain
  default: strip-unknown is the only correct behavior for a plugin that has
  not declared a serving-stack dialect). Overrides:
  OpenAiCompatibleProviderPlugin → ChatTemplateKwargs,
  OllamaProviderPlugin → OllamaThink. OpenAI, Anthropic, Copilot, OpenRouter,
  VeniceAI inherit None (strip only).
- ReasoningSuppressionChatClient (Netclaw.Daemon, beside
  VendorOptionsChatClient) wraps EVERY client ProviderPluginFactory.Create
  returns: it always removes the intent key, and when true maps it to the
  declared dialect. Mutates options in place per the established
  VendorOptionsChatClient pattern (call sites build fresh ChatOptions per
  call, so no retry hazard).
- MemoryCurationActor.TryLlmEvaluationAsync now sets only the intent key.

The strip guarantee applies to all roles/providers, so any future call site
can use the intent key without knowing which serving stack answers.

Tests: ReasoningSuppressionChatClientTests (dialect mapping, unconditional
strip, false-value strip-without-map, pass-through untouched, null options,
streaming parity), plugin dialect declarations, and a factory regression
guard that every created client carries the wrapper. Daemon.Tests 825/825,
Actors.Tests 2531/2531 green; slopwatch 0 issues; headers verified.
