v0.5.0 Release Notes

Version

v0.5.0

Dist Tag

latest

This is the stable release-prep record for the gate-first 0.5.0 line.
Publishing to latest requires QA release GO, npm registry gitHead/shasum
verification, and only then the v0.5.0 tag.

Pre-publish registry state at prep time:

  • persona-harness@latest: 0.4.0;
  • persona-harness@next: 0.5.0-rc.2;
  • persona-harness@alpha: 0.3.9-alpha.8;
  • persona-harness@0.5.0: not published;
  • local/remote v0.5.0 tag: not present.

Summary

0.5.0 makes Persona Harness gate-first by default.

The product center is the local CLI completion gate:

  • workflow/check/finish/archive gates;
  • PH-generated evidence and explicit verification records;
  • deterministic conformance blockers;
  • TDD evidence rail and read-only TDD status helper;
  • read-only evidence reports, including A/B and P-minus decision support.

OpenCode runtime guidance remains available as explicit opt-in preview behavior,
not the default product path.

Default Runtime Behavior

Default backend bootstrap is gate-first:

npx ph bootstrap backend

The default setup keeps model-facing runtime guidance off:

  • features.runtimeInjection=false;
  • enforce.systemConstitution=false;
  • enforce.executeVerification=false.

To opt into model-facing runtime guidance:

npx ph bootstrap backend --runtime-injection-preview

Strict mode remains an intentional heavier opt-in:

npx ph bootstrap backend --strict

Strict mode opts into runtime guidance, system constitution, and direct
verification. It is still not generated-app product-quality certification or a
closure guarantee.

Evidence And P-minus Interpretation

0.5.0 includes the accepted P-minus aggregate-vs-paired interpretation
cleanup.

ph evidence pminus-report --json reports paired consistency metadata for key
metrics, including candidate-lower/candidate-higher/tied counts and sign-test
p-values. Aggregate-lower provider-token evidence with weak paired consistency
is reported as descriptive local evidence only and lowers the decision hint to
keep-gathering.

For the accepted clean-exit calibrated fixture, aggregate provider-token mean
was lower for PH ON, but paired evidence was inconsistent: ON was lower in
3/10 pairs with sign-test p=0.34375. That is not token-saving or
product-efficacy evidence.

Optional Developer Integrations

Optional integrations remain explicit:

  • ph bootstrap backend --codegraph-preview registers the external CodeGraph
    wrapper integration when requested. It is not PH-owned CodeGraph, not a
    codegraph replacement, and not default behavior.
  • ph bootstrap backend --lsp-preview registers the LSP MCP wrapper preview.
    Missing dependencies keep a protocol-alive unavailable facade. No real Java
    LSP effectiveness or default LSP claim is made.
  • ph bootstrap backend --runtime-injection-preview enables optional
    model-facing PH guidance.

Accepted Evidence Summary

The stable direction is based on accepted local and registry evidence from the
0.5.0-rc.2 cycle:

  • registry 0.5.0-rc.2 package/runtime smoke verified gate-first default
    bootstrap and explicit runtime-injection preview behavior;
  • timeout-bounded 10-pair PH OFF/ON A/B produced negative/partial scoped
    evidence;
  • clean-exit calibrated 10-pair fixture passed evidence integrity, but paired
    statistics were inconsistent and did not support token-saving or product
    efficacy claims.

These results justify the default-off runtime guidance policy and the
gate-first release message. They do not prove a universal effect.

Claim Audit

Do not claim:

  • token saving or provider-token saving;
  • product efficacy or navigation benefit;
  • app/product quality guarantee;
  • full TDD framework, scaffolding, coverage, mutation testing, or test
    sufficiency;
  • CodeGraph or LSP default behavior or effectiveness;
  • broad AST/linter product or general architecture correctness;
  • broad reliability, closure guarantee, or generated-app certification;
  • Codex support or code-nav replacement;
  • automatic downgrade/removal beyond read-only P-minus decision support.

Allowed wording:

  • gate-first default;
  • runtime guidance default-off and opt-in preview;
  • P-minus reports aggregate-vs-paired consistency and lowers weak aggregate-only
    evidence to keep-gathering;
  • finish/evidence gates block explicitly defined unverified completion paths.
