From d011849bfb7d5bea887fbc7d9df4b43996931ba7 Mon Sep 17 00:00:00 2001 From: Marcos Pereira Date: Wed, 29 Jul 2026 17:22:33 +0100 Subject: [PATCH 01/36] docs: symbol usage inventory for simplification Enumerates all 265 symbols exported from the index.ts of core, mastra, models, eval, server and vercel, and classifies each as public / internal / delete based on an import-aware scan of every consumer (examples, skills, scripts, governance, looprun-bench, agentspec, yntelli) plus the two shipped CLI bins and the agentspec guard catalog. Result: 77 public, 35 internal, 153 with no consumer outside the defining package. Re-verifies the 16 pre-seeded zero-usage claims (all confirmed) and records six spot-checks.

Added a pass-C closure check resolving every consumer binding against the owner of the name: validateSpec is the only such case in the corpus. - eval.agentForCase and eval.stripGovernance delete -> public, reached by agentspec's synth-fork.mjs through a computed importFromCwd(). - core.renderTurnPrompt internal -> public, same mechanism in synth-fork.mjs and extract-fork.mjs. Found in re-verification. - models.localModel and its three companion types public -> internal: the earlier promotion rested on README evidence, and verdicts are usage-based. The docs/exports conflict is recorded for Task 12. Corrections without verdict impact: fixed the false claim that foldRow, isSingleClause and DEFAULT_POLARITY_LEXICON are unreferenced (all three are used inside coherence.ts; only findUnassessableLines is genuinely dead); defined what the same-package column measures and warned that a dash never authorizes erasing an implementation; widened the doc sweep to READMEs, GUARDS.md, governance/ and CHANGELOGs, attaching Task 12 notes instead of promoting on doc mentions; disclosed the 20 non-barrel src exports and the 28 ./testing symbols as out of scope; flagged the stale vendored guard-catalog snapshots and the three consumer files that import symbols which do not exist. Totals: 77 public / 37 internal / 151 delete (was 77 / 35 / 153).

The +`doc hits` column counts `*.md` mentions across `docs/` (excluding this plan's own files), `skills/`, +`examples/`, `governance/`, the root README, every `packages/*/README.md`, `packages/core/GUARDS.md`, +every `packages/*/CHANGELOG.md`, and `agentspec/skill` + `agentspec/docs`. + +CHANGELOG hits were surveyed and **excluded from the notes** — a symbol named in a historical release +entry is not documented API. Notes cite only README / `GUARDS.md` / `governance/`. + +Applying this policy consistently cost one earlier call: the first revision promoted `localModel` and +its three companion types to public on README evidence. Its **real** code usage is +`packages/mastra/canary/guard-canary.canary.ts` — a sibling package — so it is now **internal**, with a +loud note that `README.md:66`, `docs/illustrated-guide.md:485` and `docs/guides/local-models.md:71` +present it as the headline API. **That conflict is real and Task 12 must resolve it**: either the docs +overstate what is exported, or `models` needs a genuine public entry point. +`localModelStatus` and `geminiFlashLiteThinkOff` keep `public` on real code evidence +(`scripts/proofs/run-canary.mjs` and `examples/` respectively). ### Companion types -Where a `*Config` / `*Options` type exists only as the parameter of a public value, it inherits that -value's verdict and carries a note (`AgentSpecConfig`, `LoopRunAgentConfig`, `LoopRunOptions`, -`ModelServer`, `ModelServerConfig`).

From bdf63386b7ba5e87ab4702ca13e121e643d495fc Mon Sep 17 00:00:00 2001 From: Marcos Pereira Date: Wed, 29 Jul 2026 17:47:16 +0100 Subject: [PATCH 04/36] docs(inventory): apply the published-bin rule evenly to models MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit packages/looprun/bin/looprun.mjs is a published bin (package.json "bin" + "files": ["dist","bin"]) and reaches resolveAlias (lines 42, 66, 88, 102) and LlamaCppRuntime (lines 68, 94, 103) by dynamic import — the same mechanism that promoted 11 eval symbols via looprun-eval.mjs and localModelStatus via run-canary.mjs. Round 1 promoted the eval side and left the models side internal, which was inconsistent. Both flip internal -> public. §3 now states the rule explicitly rather than leaving it implicit in the per-file table, so it cannot be applied unevenly again: a symbol a published bin calls is user-facing regardless of which package owns the bin. models: 2/6/16 -> 4/4/16. Totals: 77/37/151 -> 79/35/151. Updated the §1 chart and bar chart, the §7.3 heading, findings 1 and 4 in §6, and the §9 revision log.

Fixes, each verified against the named source line: - drop "bring your own loop" (06.4): closing that loop needs recordToolResult, resultOk and isTerminal, all internal, so a taught version would leave the ledger empty and every history-keyed guard silently never firing. Its ten symbols demote to @looprun-ai/core/internal, reason "no tutorial home" - promote the types the reader must author but could not name: Dim, Hook, ToolTarget, AgentScope, TerminalPolicy (core spec/guards), TurnInput, RunResult, TurnRecord, RuntimeDeps (runSpecConversation), StateView, and the eval subject-directory types (Subject, SubjectCase, CaseTurn, CaseInvariants, ReqCall, RubricItem) - state that the scheduler artifacts are authored in docs/tutorial/snippets/ by tasks 8-9; examples/calendar is a seed with no code - correct worldFromTools (native-tools mode, exec throws); 03 teaches hand-writing AgentWorld as the certified path - rescope 06 to server + local models; decoding trio moves to 05 - add per-chapter import specifiers; vercel excluded as a non-functional stub - GUARD_CATALOG ships on /internal, not the public barrel (plan amendment) Two rules now decide types (annotation rule, taught-field rule) so the promotion set is bounded and reproducible.

Everything with an `internal` verdict in the symbol inventory (§7.1, 37 symbols) moves to the new `@looprun-ai/core/internal` subpath: the guard-catalog tables, spec binding resolution, the trunk renderer, model settings, and the whole governed-turn seam (ledger + terminal protocol + prompt renderer + turn machine). That subpath carries no compatibility promise. `delete`-verdict symbols only leave the barrel — no implementation is erased; the inventory's §2 rule holds (every one of them still has an internal or test caller). In-repo consumers (mastra, eval) and the core/mastra tests now import internals from the subpath or from the owning module file; no test was weakened or dropped. Verified: `pnpm -r build` (7/7) · `pnpm test` (773 tests, 0 failures) · `pnpm typecheck` (8/8, incl. examples/hermes-sim).

TYPE-CLOSURE RIDER. Cutting the barrel to the taught 51 made public signatures uncompilable downstream: a consumer building with `declaration: true` hits TS4023/TS2742 the moment it writes `export const w = validateSpec(spec)` or subclasses AgentSpecBase, because SpecWarning / AgentControls / ChainSpec / StateDirective / GuardBinding / MutatorBinding / Layer / SpatialEdge / ReplyMutator / SamplingSettings / TokenUsage are named by no entry point. Both barrels now export the transitive type closure of their own signatures as type-only riders (11 on `.`, 8 on `/internal`), derived with the TS compiler API rather than hand-picked. Riders are not taught and are not counted in the 89 — recorded as outline §7 and inventory §9 round 5. New proof `test/proofs/declaration-emit.test.ts` compiles two real consumer modules from a temp dir whose node_modules/@looprun-ai/core symlinks to this package, so resolution goes through the real `exports` map — which also makes it the first test covering the `./internal` condition. It carries a self-test that TS4023/TS2742 are in fact reported. 2. The src/index.ts header claimed everything cut was "still available from /internal". False: ~58 former exports (renderTrunkBlocks, chainOrder, resolveBindings, TERMINAL_TOOLS, the coherence set, …) are on neither barrel. Reworded to name all three destinations, module-local included, and to say Tasks 5/6 own their fate. 3. GuardExecutionError is thrown across the package boundary at guard authors but was reachable from no entry point, so `e instanceof GuardExecutionError` was unwritable downstream. Exported from /internal; whether chapter 04 teaches it (promoting it public) is deferred to Task 10 as outline §6 decision 8. 4. SURFACE LOCK. Tasks 4-7 all edit this barrel and nothing failed if it drifted. `test/proofs/surface-lock.test.ts` asserts the exact export-name sets of both entry points against three hardcoded arrays (51 taught by chapter, 11 riders, 46 internal), via the TS compiler API over src so types count and no build is needed. A deliberate surface change must edit the arrays. Verified: pnpm -r build 7/7 · pnpm typecheck 8/8 · pnpm test 781 passed, 0 failed (was 773; +8 from the two new proofs).

charset=UTF-8 Content-Transfer-Encoding: 8bit The 1427-line guards.ts becomes packages/core/src/guards/, one file per tutorial category — flow, args, world, confirmation, honesty, reply, custom — plus shared.ts (module-local helpers), catalog.ts (the vocabulary as data) and index.ts (the single import site). Every factory body moves verbatim: the only edits inside the moved code are the `export` prefix on the shared helpers. catalog.ts adds GUARD_CATALOG: one GuardCatalogEntry per exported factory (summary / whenToUse / example), the data Task 10's chapter-04 generator reads. It ships from @looprun-ai/core/internal, not the public barrel (outline §6, decision 4) — documentation infrastructure, not authoring vocabulary. The three kind-classification registries (DENY_ONLY_PROSE_KINDS, CONFIRM_CLASS_KINDS, ARMED_SEAMS) move there with it and keep their /internal export. guard-catalog-parity now scans the directory and gains a second lane: every exported factory has exactly one catalog entry and vice versa, every example calls its own factory, every entry sits in the file that exports it. The surface lock's INTERNAL array grows by the two new seam symbols; TAUGHT and RIDERS are untouched.

Task 10's chapter groups by phase, as the agentspec reference does. - guard-catalog-parity gains two lanes: the hook must be one of the four, and the tricky rows are spot-asserted (noInstructionFromData=preTool, jargonScrub=onReplyMutate, resultInvariant=postTool, pendingConfirmMustAsk=onReply). - Gate hardening: both source-scanning tests drop the `f !== 'shared.ts'` filename skip. They already discriminate by return type, and the skip would let a Guard-returning factory dropped into shared.ts escape the ratchet. - whenToUse rewritten for confirmFirst, noFalseFailureClaim and degenerationGuard — the discriminating situation first, configuration second. confirmFirst's example is now the shipping string overload confirmFirst('confirmed'), and its summary records the construction-time throw on confirmFirst('prior-ask'). - Outline amended: chapter 04 is 30 catalog rows + canonArgs taught in prose (it returns a string, not a Guard — §3 and §6 decision 2); §6 decision 4 records the hook field. The §4 row and every symbol count are unchanged. - Stale path comments: test/proofs/catalog.ts, ratchet.test.ts; ledger.ts now imports canonArgs via ./guards/index.js like spec.ts.

charset=UTF-8 Content-Transfer-Encoding: 8bit Review follow-up on 55b8ac5. Its message says "15 census cases" and the first cut of the record said 14; both double-counted. MEASURED (vitest, and grep -c on the file at 4b59968): trunk-provenance.test.ts goes 36 cases -> 24, i.e. 12 deleted outright query (a) 4 · query (b) 2 · query (c) 2 · B4 2 of 3 · I7 2 of 3 2 rewritten the mutator adds no bytes · the polarity markers are English-only 1 assertion dropped findSubjectlessLines, inside a surviving case The by-describe axis (4/2/2/2/2) and the by-symbol axis (findMultiOwnerSubjects 3, mutatorLines 2, …) count the same 12 cases; they differ only because the mutator-as-owner case calls both symbols. Report and record now print both. (55b8ac5's own message could not be amended — history rewriting is blocked in this environment — so this commit is the correction of record.) Also in the Task-5 record: - Disclose that GUARD_KIND_SUBJECT lost its `jargonScrub: 'term-substitution'` entry, with the inertness argument: the table is read only by deriveSubject <- trunk.ts#line() <- rendering a guard's prose(); a ReplyMutator has no prose(), so no TrunkLine can carry that kind. - Fix the malformed table (header/separator inverted). - Fix the arbiter claim: foldTrunk(renderTrunkBlocks(…)) === renderScopedSpecTrunk(…) is INTRA-COMMIT self-consistency; the repo pins no cross-commit trunk snapshot. Cross-commit identity is cited as REVIEW evidence — sha256 f695126…, 6999 bytes, identical at 4b59968 and 55b8ac5 over a three-trunk fixture incl. installed jargonScrub — not as an in-repo pin. Governance gap: `check-record-required --base main` was passing VACUOUSLY, the Task-5 record silently covering the 24 governed paths of Tasks 3 and 4 while its body says no guard was touched (true of Task 5, false for the branch). Two retroactive records fill it, both generated by `pnpm proofs:record` with fresh tallies and both disclosing that they attest branch state, not an at-the-time run: - 2026-07-29-core-internal-subpath.md — Task 3 (5b5e30f, e6860ec) - 2026-07-29-guards-split-catalog.md — Task 4 (08fecd0, 4b59968) MATRIX regenerated (6 records). core/src/index.ts drops the planning-internal "Task 5" reference for timeless prose.

The one residual was half-open visibility. Seven symbols in runtime/*.ts carried `export` while no barrel, no sibling package and no test imported them — TERMINAL_TOOLS, TERMINAL_PROTOCOL, TERMINAL_PROTOCOL_REPLY_ONLY (terminal.ts), uploadDisplayLabels, isReplyOnly (prompt.ts), applyMutators, checkReply (turn.ts). Each has an in-file caller, so only the keyword goes; the implementations are byte-identical. RuntimeTurnInput (types.ts) is erased: a `= TurnInput` alias with zero references anywhere.

No implementation with a live caller was erased; the one exception, `models.localModelClient`, had zero references in this repo and in looprun-bench / agentspec / yntelli, and lived inside the barrel file. The published bins keep their contract: `looprun-eval` reaches 11 eval symbols and `bin/looprun.mjs` reaches 3 models symbols through a dynamic PACKAGE import, so those are public by that fact — each lock asserts them separately (eval's reads the bin's actual `api.` accesses rather than a maintained list). `TurnEvent.meta` decision (left open by the Task 7 review): the server's `LoopRunResultMeta` mirror is exported as a rider rather than inlined structurally, so the mirror keeps exactly one name and `meta-mirror.test.ts` keeps pinning the type `TurnEvent` really uses. Recorded in the outline §7 and inventory §9 round 6. Three new surface locks (copying mastra's compiler-API mechanism) hold all of it; each was sabotage-verified to fail on drift. Rider sufficiency was checked by compiling a synthetic consumer with `declaration: true` against the built packages.

Ships the running example's shared modules (outline §2): the scheduler spec (AgentSpecBase subclass, scope, terminal, contract, a custom no-double-book gate, destructiveTools ⇒ auto confirmFirst on cancelEvent), its hand-written AgentWorld, its ToolDef surface, plus the seeded 02-hello-world snippet. Gates: `pnpm -r --if-present typecheck` picks up the package, and a two-test vitest smoke run keeps the world honest at runtime, not only at type level.

Reworded to say the eval runner throws at run start and LoopRunAgent does not check it today. No code changed. - 03: system-prompt order redrawn from trunk.ts:293-337 — voice, scope, core rules, flow, tool rules, governance, persona+behavior, languageClause LAST. The old diagram put scope below core rules and languageClause in the head. - 03: mcp.getTools() -> listTools(), plus the namespacing (serverName_toolName) and deny-by-default surface intersection (agent-construction.ts:80-97). Applied in the parked chapter-06 text, since the section moved. - 01 + 03: the veto is the tagged governance envelope (turn.ts:33-73), not a bare { success:false, error }. 01 now teaches the world-refusal vs guard-correction distinction, which is the point of the discriminator. - 02: hello world was not runnable as printed — added the copy-the-scheduler step, type=module and npx tsx notes, and scoped "twenty lines" to the agent file. - 02: model equivalence downgraded to same family (the harness pins the thinking-off variant); "wording constrained by machine checks" replaced — the language layer is never gated, it is measured. - 03: auto-install box scoped (lexicon.falseFailureClaimRe adds a sixth guard; confirmMechanism selects arg vs prior-ask), and `mode` documented as a required, near-vestigial field. Contract amendment (controller ruling): worldFromTools + StateView move from chapter 03 to chapter 06 — 03 13->11, 06 11->13, total still 89, no verdict changed. Recorded in 00-outline.md §7 and symbol-inventory §9 round 7; mcp-tools.md now absorbed by 06. Chapter 03 keeps a 3-line forward reference, and the section text is parked (with the listTools/namespacing/refresh-is- fire-and-forget fixes applied) for Task 11. Also: 03 §7's index-signature essay condensed to a callout, class diagram corrected, addGuard's elided `layer` field marked, scope's all-or-nothing rendering stated, and the chapter's "every block is quoted" umbrella replaced with the honest excerpt-vs-signature split.

The hand-written half teaches the four vocabulary types (Guard, GuardCtx, ObservedCall, Dim), canonArgs as a helper in prose, cross-references addGuard to chapter 03, and closes with writing a custom guard. GuardExecutionError stays on /internal (outline §6 decision 8): §6 MENTIONS it as the diagnostic a throwing check produces, but does not teach its API — the intended reaction is to fix the guard, not catch the error. Drift gate: `node scripts/gen-guards-chapter.mjs --check` exits 1 on drift, and runs both at the end of the root `pnpm test` chain and as its own CI step.

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.

It absorbs docs/guides/eval-config.md and docs/guides/measured-loop.md (both die in Task 12). Chapter 06 (advanced) teaches its 13: the OpenAI-compatible server (4), the local-model seven, and worldFromTools/StateView moved here by the outline §7 amendment. It absorbs docs/guides/local-models.md, packages/server/README.md and docs/guides/mcp-tools.md. @looprun-ai/vercel gets one honest line: a reserved stub whose factory throws. New snippets: 05-running-and-eval.ts, 06-advanced.ts, and a real eval subject (scheduler-subject/) over the shared scheduler — norms/gen/evals/ask plus the judge prompt. Its smoke test runs a scripted governed conversation (the clash gate really vetoes) and asserts the five preflight lints are clean. The scheduler modules' relative imports now carry the .ts extension: the subject is imported by node through loadSubject, where a .js specifier does not resolve to a .ts file. worldFromTools/StateView moved out of the 03 snippet with their chapter; the mastra surface lock's comment labels follow. Terminal transcripts are labelled: help, lint (clean and failing) and the three seal commands are real runs on this repo; run/fold/cert need a live model and are marked as illustrative shapes. --- docs/tutorial/05-running-and-eval.md | 660 ++++++++++++++++++ docs/tutorial/06-advanced.md | 494 +++++++++++++ docs/tutorial/snippets/03-agent-anatomy.ts | 33 +- docs/tutorial/snippets/05-running-and-eval.ts | 133 ++++ docs/tutorial/snippets/06-advanced.ts | 129 ++++ docs/tutorial/snippets/package.json | 10 +- .../scheduler-subject/ask/targets.json | 9 + .../snippets/scheduler-subject/evals/cases.ts | 76 ++ .../scheduler-subject/evals/judge-prompt.md | 24 + .../snippets/scheduler-subject/gen/tools.json | 29 + .../snippets/scheduler-subject/gen/world.ts | 22 + .../snippets/scheduler-subject/norms/index.ts | 22 + docs/tutorial/snippets/scheduler/contract.ts | 6 +- .../tutorial/snippets/scheduler/hello-spec.ts | 2 +- docs/tutorial/snippets/scheduler/spec.ts | 4 +- docs/tutorial/snippets/scheduler/tools.ts | 2 +- docs/tutorial/snippets/scheduler/world.ts | 2 +- .../snippets/test/05-running-and-eval.test.ts | 94 +++ docs/tutorial/snippets/tsconfig.json | 3 +- packages/mastra/test/surface-lock.test.ts | 8 +- pnpm-lock.yaml | 18 + 21 files changed, 1737 insertions(+), 43 deletions(-) create mode 100644 docs/tutorial/05-running-and-eval.md create mode 100644 docs/tutorial/06-advanced.md create mode 100644 docs/tutorial/snippets/05-running-and-eval.ts create mode 100644 docs/tutorial/snippets/06-advanced.ts create mode 100644 docs/tutorial/snippets/scheduler-subject/ask/targets.json create mode 100644 docs/tutorial/snippets/scheduler-subject/evals/cases.ts create mode 100644 docs/tutorial/snippets/scheduler-subject/evals/judge-prompt.md create mode 100644 docs/tutorial/snippets/scheduler-subject/gen/tools.json create mode 100644 docs/tutorial/snippets/scheduler-subject/gen/world.ts create mode 100644 docs/tutorial/snippets/scheduler-subject/norms/index.ts create mode 100644 docs/tutorial/snippets/test/05-running-and-eval.test.ts diff --git a/docs/tutorial/05-running-and-eval.md b/docs/tutorial/05-running-and-eval.md new file mode 100644 index 0000000..442b54d --- /dev/null +++ b/docs/tutorial/05-running-and-eval.md @@ -0,0 +1,660 @@ +# 05 · Running and eval + +**What you get from this chapter:** how to run a spec over a scripted conversation, and how to turn +"it seemed fine" into a number you can re-run.
