The quick-start demo shows a hint with `--recall`. .NET only: the Python and Go ports and the contract are unchanged. +### The recipe: what the working call produced (story 28.4) + +- **A vouched result excerpt on the working attempt.** `ExperienceCaptureOptions.RecipeResultExcerpt` (off by default) + lets the host vouch, per call that returned, for a short excerpt of its result. Capture sanitizes it with the + `ToolResult` policy, cuts it after sanitization to `CaptureLimits.MaxRecipeExcerptLength` (200) characters, never + between a surrogate pair, and stores it as `ToolCallRecord.RecipeExcerpt` (an init-only property, in the payload only + when set). A failed call never gets one; a callback that throws records nothing and is reported once per run at the + new stage `ExperienceCaptureFailureStage.RecipeExcerpt`, by type only. Injection shows it only on the `Worked:` + attempt, for a tool `ExperienceInjectionOptions.RecipeExcerpts` names, as `tool(...) [returned: "…"]`, quoted and + bounded like an argument string; the recall hint's `worked:` line renders the same way. With none of it set, every + record, payload, block and fixture is byte for byte what it was. +- **One place to consent.** `AgentExperienceOptions.Recipe(toolName, arguments, resultExcerpt)` sets the capture + argument allowlist, `ApproachArguments`, the excerpt callback and `RecipeExcerpts` for a tool together. The + quick-start sample's `--recipe` switch shows one. +- **Signed: claims version 4, fail closed.** `SignClaimsVersion = 4` signs `HMAC-SHA256.aexp-prov.v4` + (`ExperienceProvenanceSignature.HmacSha256ClaimsV4`), version 3 plus each call's excerpt. The default stays 3, which + signs every record as before and leaves excerpts unsigned, so with signing on an excerpt is shown only under a version + 4 signature that verifies (`ExperienceRetrievalService.AreRecipeExcerptsConfirmed`); records trusted unsigned or listed + as reviewed never show one. To show recipe excerpts with signing on, set `SignClaimsVersion = 4` once every verifying + node runs this release (an earlier build refuses a version 4 signature). `HistoricalReferenceWriteSettings` shows + excerpts only with `AreRecipeExcerptsConfirmed` or the explicit `ShowRecipeExcerptsWithoutSigning`. A lone surrogate + in an excerpt becomes U+FFFD at capture, so the record can always be signed and stored; an excerpt that is empty once + cleaned keeps the call's `[returned]` marker. +- **Grants.** `ExperienceGrantRequest.RecipeExcerpts` / `ExperienceGrant.RecipeExcerpts` name the tools whose excerpts + an owner consents to show a recipient (only under a level that shows the approach), surfaced on reads as + `ExperienceRecordGetResult.GrantRecipeExcerpts`, `RankedExperience.GrantRecipeExcerpts` and + `ExperienceInjectionDecisionContext.GrantRecipeExcerpts`.

Every record that validates against the 1.0 schema validates + against it. +- **Read and kept.** A port reads the member when present, keeps it on its tool call, and writes it back exactly as + read (absent when absent), so a record a port reads and writes again is unchanged. A port is not asked to capture + one: no finalize fixture carries one, and how a host vouches for an excerpt is each framework's own. +- **Signing stays .NET-only, and so does confirmation.** The .NET library signs claims version 4 + (`HMAC-SHA256.aexp-prov.v4`, which covers the excerpt) only under `SignClaimsVersion = 4`, and with signing configured + it shows an excerpt only when a version 4 signature verifies. As for every signature, a port writes none and never + changes one it reads. +- **Port limitation: a port does not confirm an excerpt.** A port cannot verify signatures, so a port that turns + `recipeExcerpts` on renders whatever excerpt the stored record carries, signed or not. A party that can write the + store can therefore put text on a port's `Worked:` line that a signing .NET reader would suppress.
