 ### Changes
 
-- Performance/models-config: add a `targetProvider` short-circuit to `ensureOpenClawModelsJson` so callers that already know which provider/model they will use (e.g. the pi-embedded runner) can skip the full implicit-provider-discovery pipeline when the on-disk `models.json` provider entry structurally matches config. Compares provider-level apiKey (env-ref aware), baseUrl, api, headers, and auth; rejects per-model transport overrides on disk; uses depth-bounded structural equality so adversarial nested input fails closed; consumes the round-4 fail-closed `ContentHashOutcome` contract from #73260 so an oversize / symlinked / unreadable `models.json` (CWE-345) forces a full plan instead of riding a stale cache entry; caches successful short-circuits in a provider-scoped readyCache entry that never blesses non-targeted callers; normalizes the configured provider through the same provider-policy hook that `planOpenClawModelsJson` uses before comparing against disk so providers with policy-injected defaults (e.g. ollama's default `baseUrl`) do not always miss the fast path; in implicit-only mode (`models: []` or omitted) requires the caller-passed `targetModel` id to be present on disk before blessing the short-circuit and folds it into the scoped readyCache key, so a stale catalog cannot satisfy the short-circuit and then trip `Unknown model` in `resolveModelAsync`.

 - Plugins/install: add `npm-pack:<path.tgz>` installs so local npm pack artifacts run through the same managed npm-root install, lockfile verification, dependency scan, and install-record path as registry npm plugins.
 - Plugin skills/Windows: publish plugin-provided skill directories as junctions on Windows so standard users without Developer Mode can register plugin skills without symlink EPERM failures. Fixes #77958. (#77971) Thanks @hclsys and @jarro.
 - MS Teams: surface blocked Bot Framework egress by logging JWKS fetch network failures and adding a Bot Connector send hint for transport-level reply failures. Fixes #77674. (#78081) Thanks @Beandon13.

+/**
+ * Real-runtime behavior proof for #73261 round-10
+ * (perf/models-config-target-provider-short-circuit, Codex P2:
+ * "Cache only the validated models.json snapshot").
+ *
+ * This script does NOT use vitest mocks of the seam under test.  It
+ * drives the real `ensureOpenClawModelsJson` against:
+ *   - a real on-disk models.json in a temp dir
+ *   - the real `safeReadFileOutcome` (lstat + bounded streaming hash)
+ *   - the real `readExistingProviderMatchesConfig` short-circuit path
+ *   - the real scoped readyCache populate / drift-detect cycle
+ *
+ * It pins the round-10 contract from three angles:
+ *
+ *   1. cache-stores-validated-outcome (perf + correctness)
+ *      Cold cache + stable disk: the disk-based short-circuit fires
+ *      AND the scoped cache is populated with the SAME validated
+ *      outcome that the structural check inspected (no second
+ *      post-validation `readModelsJsonContentOutcome` read).  We pin
+ *      this by counting `fs.promises.lstat` calls against models.json
+ *      during the short-circuit path.  Pre-fix the count was 2 per
+ *      successful short-circuit (one from `safeReadFileOutcome` inside
+ *      `readExistingProviderMatchesConfig`, one from the post-validation
+ *      `readModelsJsonContentOutcome`).  Post-fix it must be 1.
+ *
+ *   2. toctou-swap-cannot-bless-unvalidated-content (security)
+ *      Pre-fix, an attacker swapping models.json bytes between the two
+ *      reads could land hash(swappedBytes) in the scoped cache, and a
+ *      subsequent targeted call would compare current disk against
+ *      hash(swappedBytes) and accept it as "the validated snapshot,"
+ *      blessing attacker-controlled provider transport.  Post-fix the
+ *      cached hash IS the hash of the validated bytes, so any swap
+ *      drift-detects on the next call.  We pin by: cold short-circuit
+ *      populates scoped cache; mutate disk to a config-disagreeing
+ *      shape (different baseUrl); next targeted call must NOT take
+ *      the warm cache path (it must re-validate, fail the structural
+ *      check against the swapped baseUrl, and fall through to a full
+ *      plan).
+ *
+ *   3. no-cache-on-uncacheable-validated-outcome (defense in depth)
+ *      When the file is unhashable (oversize), the structural check
+ *      returns `{ matches: false }` before we reach the cache populate
+ *      path.  This is behaviorally equivalent to the round-9
+ *      "if validated outcome is uncacheable, do not cache" guard but
+ *      with the redundant second read removed.  We pin by oversizing
+ *      models.json and confirming the next targeted call runs a full
+ *      plan (no cache hit, no short-circuit).
+ *
+ * The proof is self-checking: any regression throws and exits
+ * non-zero.  Captured output must show "All runtime assertions
+ * passed." on success.
+ *
+ * Run with:
+ *   pnpm tsx scripts/proof-73261-validated-outcome-cache.ts
