Rule text: converged candidates by multi-angle convergence, models only through a converged harness - #1049

Scope

• What this PR changes, in one or two sentences: on all six always-loaded rule surfaces, the "Decide by evidence" bullet gains two foundation sentences: "Use only converged candidates" (trial after the layer's screen, its requirements checked at a pin; a default only when the layer's multi-angle convergence agrees; no single angle makes a candidate a default) and "Use models only through a converged harness with its full layers". Its not-evidence clause now reads "alone are not evidence", as does the long form in docs/harness-defaults.md:9. Recorded in docs/decisions/2026-10-12-converged-candidates-only.md. No tool, hook, check or runtime behavior changes.
• Base commit: 703d588c5660d698a87b622efe0e3bd8c22f7e29 (rebased from 7151664c9, a registry-only rebase: only manifests/evidence.json was resolved, by re-registering each commit's files from the merged bytes).
• Lane: lane:foundation
• Owned paths touched: AGENTS.md, examples/claude-native/CLAUDE.md, adoption/templates/codex.AGENTS.template.md, adoption/scaffold/AGENTS.md, adoption/new-wsl/claude-user-instructions.md and adoption/new-wsl/codex-user-instructions.md (both generated), docs/harness-defaults.md, tests/test_install_claude_profile.py, tests/test_codex_worker_lane.py, manifests/evidence.json, the new decision record.
• Commits (rebased ids): e18efdcc (first sentence), d945f4ce (harness sentence), e4d8f694 (trial/default split), 37577653 (multi-angle wording and "alone"), 14ea7e1b (record only: how the rule applies to every layer, the freeze, revisits and the north star), 67f9e826 (review round 1 for both reads: private digests removed, licence never a disqualifier, the protocol's reopen rule quoted as written, the harness-defaults clause, the screen defined and "no single angle makes a candidate a default"). Each later commit is a fast-forward; the earlier wordings never reached main and are listed in the record.

tests.test_codex_worker_lane and tests.test_scaffold_repo are added to the brief's four modules because this change re-pins TOP_RULE_SHA256 and moves the scaffold block with the Codex template. The two modules in the second run read docs/harness-defaults.md.

Decision record

docs/decisions/2026-10-12-converged-candidates-only.md: the rule, its basis, what it changes, how it applies to every layer and the freeze, alternatives, the comparison that would overturn it. Supersession: no decision record is superseded; the not-evidence clause is amended in place.
