The library is a neutral machine. (CI: scan.) - -### 3.6 Nothing generative ships self-reviewed — the debate gate - -Every generated artifact (a tool surface, an eval case, a spec) is validated by **adversarial -debate, never self-review** — because measured, generators grade their own homework badly: -raw generations carry heavy noise, and *self*-refinement is **worse than no verification at all** -([BARRED](https://arxiv.org/abs/2604.25203)).

Reverses round 1's change #4, on a different and stronger authority: #4 correctly refused a promotion based on a *doc mention*; this one is based on the *tutorial contract*.

Round 4 reopened that. + +### Round 4 — two independent reviews of the outline + +The round-3 outline placed all 83 symbols, but three chapters could not actually be *written* from +the surface they claimed: the types the reader must author were not exported. Round 4 fixes the +contract in both directions. + +| # | change | evidence | +|---|---|---| +| 7 | **10 core symbols public → internal**: `createLedger` `beginTurn` `resolveGuards` `evaluatePreTool` `enforcePostTool` `redriveMessage` `finalizeReply` `ReplyViolation` `renderScopedSpecTrunk` `renderTurnPrompt` | reason: **no tutorial home**. Outline §6.4 ("bring your own loop") was dropped as unteachable — closing that loop needs `recordToolResult`, `resultOk`, `isTerminal`, `terminalProtocol`, `TurnLedger`, all internal. Without `recordToolResult` the ledger's `observed` stays empty and every history-keyed guard (`confirmFirst`, `noDuplicateCall`, `requiresBefore`, `destructiveThrottle`) silently never fires — a chapter that ships a governance hole. The seam stays whole behind `@looprun-ai/core/internal` for the bench shim and the agentspec fork scripts, which is what they already are: integrators, not the tutorial's audience | +| 8 | `core.Dim` delete → **public** | `custom({ kind, dim, check, prose })` (`guards.ts:24`) requires `dim: Dim`. Chapter 04 teaches `custom` as the escape hatch, so the vocabulary block is `Guard` `GuardCtx` `ObservedCall` `Dim` | +| 9 | `core.Hook`, `core.ToolTarget` delete → **public** | `AgentSpecBase#addGuard(hook: Hook, target: ToolTarget, guard: Guard, opts?)` (`spec.ts:494`) is the mechanism that binds any factory to a spec — and it throws on an illegal dim×hook pairing. Chapter 03 teaches it. **`Layer` deliberately NOT promoted**: it appears only as `opts.layer`, and layers (`'minimal' | 'base' | 'full' | 'agent'`, `spec.ts:36`) are the framework's own auto-install tiers, which the tutorial does not teach the reader to set | +| 10 | `core.AgentScope`, `core.TerminalPolicy` delete → **public** | the design assigns "scope, tools, terminal" to chapter 03; `AgentScope` is an authored `{ lane, others }` object and `TerminalPolicy` an authored `(world) => boolean`. **The other `AgentSpecConfig` field types stay non-public** (`SpatialEdge`, `StateDirective`, `ChainSpec`, `SamplingSettings`, `MutatorBinding`) because chapter 03 does not teach `flow` / `directives` / `chains` / `sampling`. The rule is stated in the outline: *a config field the tutorial teaches has its authored type public; a field it does not teach keeps its type off the barrel* | +| 11 | `core.TurnInput`, `core.RunResult`, `core.TurnRecord` internal → **public**; `mastra.RuntimeDeps` delete → **public** | `runSpecConversation(spec: AgentSpec, turns: TurnInput[], deps: RuntimeDeps): Promise` (`run-conversation.ts:73`) is chapter 05's headline call and every name in it was unexported. `TurnRecord` rides along as `RunResult.turnRecords`' element — the shape 05 asserts on | +| 12 | `mastra.StateView` delete → **public** | `worldFromTools(opts: { stateView?: StateView })` (`world-adapters.ts:24`) — the reader authors the state view. Also corrects the outline's description of that function: it synthesizes a **native-tools-mode** world whose `exec` **throws**; it supplies state only | +| 13 | `eval.Subject`, `SubjectCase`, `CaseTurn`, `CaseInvariants`, `ReqCall`, `RubricItem` delete → **public** | chapter 05 teaches the **subject directory contract** (`norms/index` → SPECS + CONTRACT, `gen/world`, `evals/cases`, `gen/tools.json`, `ask/targets.json`). The reader authors `evals/cases` as `SubjectCase[]`; `Subject` is `loadSubject`'s return and the parameter of `agentForCase` and `lintSubject` | + +**Also decided in round 4** (recorded in the outline, no verdict change here): `GUARD_CATALOG` + +`GuardCatalogEntry` ship on `@looprun-ai/core/internal`, not the public barrel — Task 10's generator +imports from `/internal`. This amends the plan's Task 4 wording ("exported publicly") to match the +contract principle: the catalog is build input for the chapter, not API the chapter teaches. + +Totals: 77 / 35 / 153 (initial) → 77 / 37 / 151 (round 1) → 79 / 35 / 151 (round 2) → +83 / 31 / 151 (round 3) → **89 / 38 / 138** (round 4). + +### Round 5 — what Task 3 found while applying round 4 + +Converging `core/src/index.ts` on the contract surfaced two things this scan, being a name-level +enumeration, could not: a **compilation** obligation and a **catchability** one. Neither is a usage +finding, so **the §1 chart stays at its round-4 values (89 / 38 / 138)** — both are recorded here as +separate, listed categories. + +| # | category | what | why it is not a verdict change | +|---|---|---|---| +| 14 | **type-closure riders** (11 in `core`) | `SpecWarning` `AgentControls` `ChainSpec` `StateDirective` `GuardBinding` `MutatorBinding` `Layer` `SpatialEdge` `ReplyMutator` `SamplingSettings` `TokenUsage` are exported from `@looprun-ai/core` as **type-only** riders; `PreToolVerdict` `GovernanceVeto` `PostToolEnforcement` `PostToolViolation` `ChainPassCtx` `ChainPassResult` `TurnPrompt` `TurnPromptInput` likewise from `/internal` | A consumer building with `declaration: true` cannot NAME these, so it fails with `TS4023`/`TS2742` on any signature that reaches them (`validateSpec` → `SpecWarning`, `AgentSpec.controls` → `AgentControls`, subclassing `AgentSpecBase` → `GuardBinding`+`Layer`). They are **not taught, not public API, and not counted in the 89** — a compilation obligation, derived mechanically from the signatures and shrinking as Tasks 5–6 shrink them. Full statement in the outline's §7; held by `core/test/proofs/declaration-emit.test.ts` (sufficiency) and `surface-lock.test.ts` (no growth). Note `GuardBinding` and `TokenUsage` are BOTH a `.` rider and a first-class `/internal` export — their internal verdict is unchanged | +| 15 | **catchable-by-class** (1) | `core.GuardExecutionError` (verdict `delete`) is exported from `/internal` by controller ruling | It is a class the runtime **throws across the package boundary** at guard authors (`spec.ts#attributeGuard`; "never swallowed, never converted into a deny"). Reachable from no entry point, `catch (e) { e instanceof GuardExecutionError }` is unwritable outside this package — a barrel-only scan sees an unused export, not a thrown type.

Same category as #14: `export type` only, **not taught, not counted in the 89**, derived from each package's own signatures. Note the eval nine include the exact types §2's annotation-rule note and the outline's §5 list call "not promoted" — that stays true: they are a compilation obligation, not surface anybody chose. Full lists and the forcing signatures in the outline's §7 | +| 17 | **`TurnEvent.meta` nameability** (decision) | `server.LoopRunResultMeta` — this package's pinned MIRROR of a type internal to `@looprun-ai/mastra` — is exported as a rider rather than inlined as a structural type in `TurnEvent.meta`, so the mirror keeps exactly one name and `packages/server/test/meta-mirror.test.ts` keeps pinning the type `TurnEvent` really uses. Rationale in the outline's §7; server's taught count stays 4 | + +**One implementation erased** (not a verdict change, recorded for the audit trail): +`models.localModelClient` — verdict `delete`, and unlike most `delete` rows it had **zero** +references anywhere: not in `packages/*/src`, not in any test, not in `examples/`, `scripts/`, +`skills/` or `governance/`, and not in `looprun-bench`, `agentspec` or `yntelli` (grep, 2026-07-29). +It was declared in `packages/models/src/index.ts` itself, so leaving it module-local would have left +dead code inside the barrel file. §2's "stop exporting, never erase" protects implementations with +live callers; this one had none. + +### Round 7 — a PLACEMENT move found while writing chapter 03 (Task 9) + +**No verdict changed and no count moved: §1 stays 89 / 38 / 138.** This round records a +chapter-placement correction only, so that the outline's §4 table and this inventory keep agreeing. + +| # | category | what | +|---|---|---| +| 18 | **placement move** (`mastra`, 2) | `worldFromTools` and `StateView` move from chapter **03** to chapter **06**. Both stay public and taught; only the chapter changes. Writing 03 showed the native-tools path is a *deployment* topic, not an anatomy one: it presupposes a second execution model (tools that execute themselves, incl. MCP), a host that owns state, and the deny-by-default surface intersection in `agent-construction.ts:80-97` — none of which a reader meeting `AgentWorld` for the first time can evaluate. It sits beside 06's other "take the same spec somewhere else" sections. **Per-chapter counts: 03 13 → 11, 06 11 → 13.** Per-package (mastra 7) and the total (89) are unchanged. Chapter 03 keeps a three-line forward reference so the reader learns the path exists.

That is also what +keeps it in sync with `agentspec/skill/references/guard-catalog.md`, which `lint-guard-catalog.mjs` +enforces in CI against the built `guards.d.ts`. **All 30 public guard factories therefore belong +here** — including the ones `AgentSpecBase` auto-installs, which no consumer imports by name but which +the lint requires to exist. + +**30, not 31 — `canonArgs` is a helper, not a factory** (Task 4 finding, adjudicated). It returns a +`string` fingerprint, not a `Guard`, and every existing gate already says so: the parity extractor +asserts `canonArgs` is not a factory, `GUARDS.md` calls it "the `canonArgs` helper", and the agentspec +reference gives it no catalog row. So `GUARD_CATALOG` carries **30 entries** — 29 guard kinds + the +`jargonScrub` mutator — and the chapter teaches `canonArgs` **in prose** (see the Task 10 amendment +below for where it landed), as the fingerprint `noDuplicateCall` is built on.

A downstream library that +builds with `declaration: true` — as `@looprun-ai/mastra` does — must be able to **name** every type +its emitted `.d.ts` mentions, and a taught signature drags untaught types behind it: `validateSpec` +returns `SpecWarning[]`, `AgentSpec.controls` is an `AgentControls` reaching `ChainSpec` / +`StateDirective` / `SamplingSettings`, `AgentSpec.guards` is `GuardBinding` / `MutatorBinding` +reaching `Layer`, `jargonScrub` returns a `ReplyMutator`. With those off the barrel the consumer +gets `TS4023`/`TS2742` ("cannot be named without a reference to …") — a break no `pnpm -r build` in +this repo can see, because each package emits declarations only for its own sources. + +**The rider:** each barrel additionally exports, as `export type` and nothing more, the transitive +type closure of its own value signatures. These are **not taught**, get no chapter, and are **not +counted in the 89** — they are a compilation obligation, listed separately so nobody mistakes them +for surface anybody chose. The closure is derived mechanically, never hand-picked, and it shrinks +automatically as Tasks 5–6 shrink what the signatures touch. Two tests hold the line: +`packages/core/test/proofs/declaration-emit.test.ts` proves the list is **sufficient** (it compiles a +real consumer against the published `exports` map), and `surface-lock.test.ts` proves it has not +quietly **grown**. + +For `core` the rider is 11 types: `SpecWarning` `AgentControls` `ChainSpec` `StateDirective` +`GuardBinding` `MutatorBinding` `Layer` `SpatialEdge` `ReplyMutator` `SamplingSettings` `TokenUsage`. +Tasks 4–7 derive their own package's rider the same way; a symbol appearing there is not a promotion +and must not be read as one. + +**The per-package rider lists** (`mastra` needs none — it re-exports core's whole barrel, and its +own three taught types are already public).

Compose it with `argRequired` when the field is also mandatory; alone it only polices the values that are actually sent. + +```ts +argFormat('bookingId', '^BK-\\d{6}$') +``` + +#### 8. `precondition` + +The call is allowed only while a predicate over the host world holds. + +**When to reach for it.** A gate whose discriminator lives in WORLD state, not in this call — the predicate never sees the acting call's arguments. If the discriminator is in the args, use `custom` instead. + +```ts +precondition((world) => world.accountActive === true, 'This account is closed — you cannot act on it.', 'act on an account only while it is open') +``` + +#### 9. `consentRequired` + +A set of writes may run only while the world says this person's consent is on record. + +**When to reach for it.** Storing, sharing or transmitting personal data. It is `precondition` specialised to a TOOL SET, which is what makes the consent posture auditable in a spec header; pair it with a conversation-scoped `maxCalls` for repeat contact. + +```ts +consentRequired({ tools: ['storeProfile'], consentOk: (world) => world.consentOnRecord === true, reason: 'No consent on record — ask for it before storing anything.' }) +``` + +#### 10. `confirmFirst` + +A destructive tool needs the user's go-ahead from an EARLIER turn — via a confirm flag probe or a prior ask. Passing a mechanism NAME to the string overload throws at construction. + +**When to reach for it.** The user must have agreed before this call runs, and the evidence has to be cross-turn — this is the consent gate itself. Its neighbours answer different questions: `destructiveThrottle` caps the blast radius of a turn that IS approved, `consentRequired` reads a standing world flag rather than the conversation, and `pendingConfirmMustAsk` gates the REPLY rather than the call. Mechanism: `'arg'` when the tool carries a confirm flag, `'prior-ask'` when it has none and an earlier question is the only possible evidence; the string overload sets the FLAG NAME, so `confirmFirst('prior-ask')` throws rather than silently building a guard that can never fire. + +```ts +confirmFirst('confirmed') +``` + +#### 11. `noActAfterAskSameTurn` + +Denies the listed tools on a turn in which the model already asked the user a question. + +**When to reach for it.** The mirror image of `confirmFirst`'s cross-turn requirement: it closes the multi-tool step that asks and executes back to back, which reads as "asked" but never gave the user a chance to answer. + +```ts +noActAfterAskSameTurn(['cancelBooking']) +``` + +#### 12. `destructiveThrottle` + +At most one destructive action that TOOK EFFECT per turn (a confirmation probe does not count). + +**When to reach for it.** Auto-installed alongside `confirmFirst`. It is the blast-radius cap, not a consent gate: it stops chained destructive calls in one turn even when each one is individually confirmed. + +```ts +destructiveThrottle(['cancelBooking', 'refundOrder']) +``` + +#### 13. `noInstructionFromData` + +Denies the listed destructive tools while an imperative sits in the conversation's tool results and no earlier turn exposed the action to the user. + +**When to reach for it.** Tool results can carry attacker-controlled text (notes, messages, tickets). The proxy is deliberately conservative — it converts a poisoned same-turn request into the legal ask-then-act two-turn flow. + +```ts +noInstructionFromData({ tools: ['cancelBooking'], instructionRe: /please cancel|delete all/i }) +``` + +### `postTool` — the call has run + +The only hook that sees `ctx.result`. It cannot veto anything — the effect already happened — so its job is to stop the RESULT from being reported as something it was not: a violation here joins the reply redrive set. + +| factory | file | what it enforces | +|---|---|---| +| [`resultInvariant`](#14-resultinvariant) | `world.ts` | A post-execution check on the tool RESULT: when the predicate fails, the violation joins the reply redrive set. | + +#### 14. `resultInvariant` + +A post-execution check on the tool RESULT: when the predicate fails, the violation joins the reply redrive set. + +**When to reach for it.** The call already ran and cannot be undone, but its result must not be reported as if it satisfied the request — an empty report, a partial write. It never vetoes the call; it corrects the reply. + +```ts +resultInvariant((result) => Array.isArray(result) && result.length > 0, 'The search returned nothing — say so instead of summarising it.', 'report an empty result as empty') +``` + +### `onReply` — the reply exists, and has not been sent + +The reply text is in `ctx.reply` and no tool can run any more.

It gates the REPLY; `confirmFirst` gates the call. + +```ts +pendingConfirmMustAsk({ askRe: /shall I|do you want me to/i }) +``` + +#### 16. `noFabricatedSuccess` + +The reply may not claim a tool's effect, cite an invented artifact label, or use a banned phrase when the tool did not succeed this turn. + +**When to reach for it.** A tool whose output the model likes to announce before it exists. Arm only the seams you need — claim language, label existence, or an unconditional ban — and ship `banProse` with every `banRe`. + +```ts +noFabricatedSuccess('generateReport', { reason: 'No report was generated this turn — do not say one was.', claimRe: /report is ready/i }) +``` + +#### 17. `destructiveClaimRequiresSuccess` + +A declarative claim that a destructive action happened is denied unless one actually took effect this turn. + +**When to reach for it.** The destructive counterpart of `noFabricatedSuccess`, attempt-keyed and sentence-scoped: with no attempt this turn a destructive verb is read-back status and is left alone, and questions or offers never count as claims. + +```ts +destructiveClaimRequiresSuccess(['cancelBooking'], { claimRe: /cancelled/i, askRe: /shall I cancel/i, offerRe: /would you like/i }) +``` + +#### 18. `noFalseFailureClaim` + +When every domain call this turn succeeded and one of them mutated the world, the reply may not claim inability. + +**When to reach for it.** The work actually went through and the model still apologises for failing — the mirror image of the fabricated-success kinds, which catch the opposite lie. It only adjudicates a turn that MUTATED the world, so an honest "I could not find it" on a read-only turn is never touched. Auto-installed when the lexicon supplies the pattern; keep that pattern to attempted-work-failure phrasing ("failed to", "went wrong"), since a broad inability regex would veto honest policy refusals. + +```ts +noFalseFailureClaim({ claimRe: /failed to|something went wrong/i }) +``` + +#### 19. `noOutOfSurfaceActionClaim` + +A declarative claim of an action whose tool is not on this agent's surface is denied. + +**When to reach for it.** The agent is expected to hand off (billing, legal, dispatch) and the model promises the handoff as done. It deliberately stops at the surface boundary, so it never double-fires with the owned-action honesty kinds. + +```ts +noOutOfSurfaceActionClaim({ actionClaims: [{ claimRe: /refund (?:has been )?issued/i, tool: 'issueRefund' }], surface: ['findBooking'] }) +``` + +#### 20. `noUngroundedRegulatedFigure` + +A figure or conclusion of a regulated class may appear only when a tool returned it this turn. + +**When to reach for it.** Legal, medical or financial surfaces. Keep `allowFromToolResults` true when a tool is authoritative for the class; set it false to ban the class outright where nothing in the world can license it. + +```ts +noUngroundedRegulatedFigure({ regulatedRe: /\b\d+\s?mg\b/i, allowFromToolResults: true }) +``` + +#### 21. `noCompetitorClaim` + +Within one sentence, a named third party plus comparative phrasing or a comparative figure is denied. + +**When to reach for it.** Any user-facing sales or support surface. The figure branch is sound by construction: no tool returns a competitor's numbers, so any such number is invented. + +```ts +noCompetitorClaim({ competitorRe: /\bAcme\b/i, comparativeRe: /\b(?:better|cheaper|faster) than\b/i }) +``` + +#### 22. `replyMustMention` + +The reply must contain at least one of the given keywords (case-insensitive). + +**When to reach for it.** A mandatory element of coverage that is the same on every turn — a referral phrase, a required disclaimer. For "name the records you just acted on", use `replyConfirmsLabels` instead. + +```ts +replyMustMention(['support@example.com'], 'Give the support address so the person can follow up.') +``` + +#### 23. `replyMaxOccurrences` + +At most n DISTINCT calls-to-action from the list may appear in one reply. + +**When to reach for it.** Anti-nag: the model stacks several different asks onto one message. It counts distinct entries, not repetitions, so one CTA restated inside a single ask still passes. + +```ts +replyMaxOccurrences(['book now', 'call us', 'subscribe'], 1, 'One ask per reply — drop the extra calls-to-action.') +``` + +#### 24. `replySingleQuestion` + +The reply must carry exactly one question mark. + +**When to reach for it.** Recovery and clarification turns, where a pile of questions at once is what stalls the conversation. Bind it to the layer that handles those turns, not to every reply. + +```ts +replySingleQuestion('Ask exactly one question so the person can answer it.') +``` + +#### 25. `replyConfirmsLabels` + +The reply must be non-empty and name every one of the given labels. + +**When to reach for it.** The model just acted on identified records and the user needs to see WHICH ones. Unlike `replyMustMention` (any one keyword), every label is required. + +```ts +replyConfirmsLabels(['BK-100234'], 'Name the booking you acted on so the person can check it.') +``` + +#### 26. `emptyReply` + +The final reply must not be blank. + +**When to reach for it.** Always on (auto-installed). It is the floor under every other reply kind: a turn that ends with nothing said is a failure no other guard would catch. + +```ts +emptyReply() +``` + +#### 27. `degenerationGuard` + +Catches leaked reasoning or tool markup, chat-template tokens and run-away line repetition in the reply. + +**When to reach for it.** The reply is broken as an ARTIFACT rather than wrong as a claim — think blocks, tool-call markup or the same line five times over. No honesty kind fires on that, because nothing was asserted; this one catches the weak-model failure class every domain shares. Always on (auto-installed); pass `selfNarrationRe` to add the language-specific third-person self-narration branch. + +```ts +degenerationGuard({ selfNarrationRe: /the assistant (?:then )?(?:called|checked)/i }) +``` + +#### 28. `minimalDisclosure` + +Caps how many records' personal FIELDS one reply may carry, and requires each named field to have been returned by a tool this turn. + +**When to reach for it.** Any surface that reads personal records.

Through looprun you are covered either way — both the runner and `LoopRunAgent` normalize flat call settings into `modelSettings` before they call Mastra — but the preset is the form that survives being passed anywhere. `maxOutputTokens` is the runaway brake: one uncapped local call decoded ~8.7k tokens over 302 s before the client gave up | +| `geminiThinkingOff()` | core | `{ providerOptions: { google: { thinkingConfig: { thinkingBudget: 0, includeThoughts: false } } } }`.
