fix(eval): reject authored direct input

[christso]

Summary

Implements Bead av-kfik.27 hard-deprecation for authored direct input in normal Promptfoo-aligned eval YAML.

• Rejects authored top-level input and inline tests[].input at schema/validator/parser/runtime load boundaries with actionable guidance to use top-level prompts plus default_test.vars / tests[].vars.
• Keeps raw-case/internal compatibility narrow: external raw-case imports through tests: file://... may still carry internal input; normal authored eval YAML cannot.
• Updates focused tests, public eval docs, Promptfoo parity docs, eval-writer skill data, generated schema, and migration guidance to make prompts + vars the canonical authoring model.
• Converts nearby legacy parser/input_files tests away from public authored direct input; input_files + input now rejects, while canonical prompt content file blocks with vars render successfully.

Promptfoo Source Evidence

Promptfoo local clone: /home/entity/projects/promptfoo/promptfoo
Evidence commit: 6bfc5a0c7f16f9c4717ac731d276b578e63d0769 (6bfc5a0 chore(deps): update modelaudit schema generator to v0.2.47 (#9635))

Claims verified from source:

• src/types/index.ts:851-858: Promptfoo test cases represent unique prompt inputs after substituting vars; vars is the test-row data surface.
• src/types/index.ts:1033-1049: suites own providers, prompts, tests, and defaultTest; prompt entries are top-level suite data.
• src/evaluator.ts:2165-2173: Promptfoo merges defaultTest.vars, scenario/data vars, and test vars.
• src/evaluator.ts:2318-2322: Promptfoo propagates default test prompts/providers onto test cases.

Verification

Passed locally:

• bun test packages/core/test/evaluation/prompt-input-authoring.test.ts packages/core/test/evaluation/input-files-shorthand.test.ts packages/core/test/evaluation/yaml-parser-metadata.test.ts packages/core/test/evaluation/validation/eval-file-schema.test.ts packages/core/test/evaluation/validation/eval-validator.test.ts packages/core/test/evaluation/validation/eval-schema-sync.test.ts
• bun run lint
• bun run typecheck
• bun --filter @agentv/core build
• git diff --check

bun run validate:examples was run and currently fails because the repo still has broad existing authored tests[].input examples: 108 eval YAML files checked, 6 valid, 102 invalid. This is recorded on av-kfik.16 for the examples-authoring worker and on av-kfik.15 with exact codemod conversion requirements. This PR intentionally does not duplicate that broad examples/codemod sweep.

Live Dogfood

Passed with local OpenAI-compatible endpoint:

AGENTV_DOGFOOD_OPENAI_BASE_URL=http://127.0.0.1:10531/v1 \
AGENTV_DOGFOOD_OPENAI_API_KEY=local-proxy \
AGENTV_DOGFOOD_OPENAI_MODEL=gpt-5.4-mini \
AGENTV_NO_UPDATE_CHECK=1 \
bun apps/cli/src/cli.ts eval run prompt-vars.eval.yaml \
  --targets .agentv/targets.yaml \
  --output .agentv/results/prompt-vars-hard-deprecation \
  --grader-target local-grader \
  --threshold 0 \
  --no-cache

Result: PASS (1/1, mean 100%) using canonical .agentv/results/prompt-vars-hard-deprecation output.

Private evidence: EntityProcess/agentv-private branch evidence/av-kfik-27-input-hard-deprecation, commit 475b3d6.

Coordinator correction: the worker briefly pushed an agentv-private branch to the public EntityProcess/agentv remote while publishing evidence. That public branch was deleted with git push origin :agentv-private; do not use commit 19612e7c as evidence.

Compatibility Decision

Normal public authored eval YAML now rejects direct input everywhere this PR touches. External raw-case files loaded through tests: file://... remain the only tested internal compatibility path for input; they are deliberately kept out of canonical public docs and covered by prompt-input-authoring.test.ts.

Beads

• av-kfik.27: implementation PR, left open for coordinator review/merge.
• av-kfik.15: updated with exact remaining codemod conversion requirements for top-level input, inline tests input, message arrays, and input_files + input.
• av-kfik.16: updated with the exact validate:examples blocker and examples migration handoff.

Current CI Status

As of coordinator review on 2026-07-04, this draft PR is not mergeable: GitHub Actions Test fails because full @agentv/core fixtures still contain legacy authored input surfaces (127 failures), and Validate Evals fails because repo examples still broadly use tests[].input. The follow-up migration work is recorded on av-kfik.15 and av-kfik.16. Keep this PR draft until those branches are sequenced and CI is green.

Evidence correction verified: public EntityProcess/agentv no longer has an origin/agentv-private branch (git ls-remote --heads origin agentv-private returns empty), and the temporary local agentv-private worktree/branch at commit 19612e7 was removed. Correct evidence is in the separate EntityProcess/agentv-private repo on orphan branch evidence/av-kfik-27-input-hard-deprecation at commit 475b3d6d5f68496bf7c3377daafa22fb0136b96d; rev-list shows no parent and the branch contains source/prompt-vars.eval.yaml, source/targets.yaml, and run-bundle/.

Codemod migration for Beads av-kfik.15.1 / av-kfik.15 is now pushed directly to this PR branch at commit 1e5d130.

Validation evidence:

• Local: bun run lint passed
• Local: bun run typecheck passed
• Local: bun run validate:examples passed 108/108
• Local: bun run test passed (agentv 746 pass, dashboard 153 pass in captured tail)
• README scan passed: no Promptfoo mentions and no public YAML/defineEval/evaluate tests[].input examples outside vars.input/task parameter usage
• Remote CI on fix(eval): reject authored direct input #1646 is green: Build, Typecheck, Lint, Test, Check Links, Validate Marketplace, Validate Evals, and Cloudflare Pages all passed on run https://github.com/EntityProcess/agentv/actions/runs/28707200216

The earlier successor PR #1650 has been merged into this hard-deprecation branch; this PR is now the green-ready branch for av-kfik.27.

Coordinator verification update after merging #1652:

• fix(eval): reject mixed criteria assertions #1652 merged into this branch and closed av-kfik.42.
• CI on promptfoo-input-hard-deprecation is green at b60671ffdbe50ba5cf4823d229041f1684f4de62.
• Local build in the integrated worktree passed (bun run build; existing dashboard chunk-size warning only).
• Live dogfood passed with a real provider and real LLM grader using gpt-5.4-mini via the available Azure OpenAI secret.

Dogfood command shape:

bun apps/cli/src/cli.ts eval run examples/features/default-graders/evals/suite.yaml \
  --test-id greeting \
  --target azure \
  --grader-target azure \
  --workers 1 \
  --output .agentv/results/av-kfik-27-input-hard-deprecation-azure-openai-20260704T140222Z \
  --threshold 0.5 \
  --no-results-push

Result: PASS, 1/1, mean score 100%.

Credential note: standard local OPENAI_API_KEY was dummy, so the successful live run used Bitwarden secret azure-openai-chris-shared, which notes gpt-5.4 and gpt-5.4-mini; the process set AZURE_DEPLOYMENT_NAME=gpt-5.4-mini.

Correction: local OpenAI-compatible endpoint dogfood was rerun and is now the primary evidence.

Evidence commit: 4f476f0

The previous Azure OpenAI run remains in the evidence branch as secondary fallback evidence; the local OpenAI-compatible run is the correct primary dogfood for this PR.
