FE-1431: Build the plugin authoring surface (cycle two) by lunelson · Pull Request #9348 · hashintel/hash

lunelson · 2026-08-26T17:16:44Z

🌟 What is the purpose of this PR?

Cycle two of the plugin authoring loop: both plugins and the repertoire are rewritten against the cycle-one review findings, the two key shapes that review demanded are changed (pattern slots and the precision list), and the key catalogue is declared frozen under ADR-0007 decision 9 because the cycle changed no key.

Draft: opened so the stack is visible end to end. The description is completed when the branch is tied off.

🔍 What does this change?

Pattern slots scoped to failing slots with wildcard validation; alternative precision demands; repertoire teaching conditioned on plugin precision; the cycle-two content pass, review resolution, freeze, and its evidence readout; the Brunch evaluation runner kept in pruned app jobs.

PR Summary

Low Risk
Changes are documentation, evaluation evidence indexing, and CI prune path copies; no runtime auth or data-path code in this diff.

Overview
Cycle-two closure for FE-1431: baseline evaluation docs now separate cycle-one live arms under transcripts/cycle-1/, point current condition 4–5 artifacts at the 2026-08-26 runs, and add a catalogue freeze verdict in readout.md (no new harness keys; residual defects routed to harness work).

The rendered teaching snapshot condition-4-system.md is rewritten to match the revised SDCPN plugin and repertoire: demand rows gain alternatives (e.g. spread or spelled out), patterns and guidance expand (lenses, techniques, licenses, motifs, close/stopping outcomes), and prose shifts from “precision” to value grade language. CONTEXT.md aligns Pattern and Repertoire definitions with slot-scoped pattern triggers and precision-conditioned repertoire applicability.

CI: prune.py copies sibling plugin-sdcpn and plugin-gherkin plugin.yaml files when the requested scope is @hashintel/brunch-agent-repertoire, with a unit test—so repertoire tests that load plugins by relative URL work in pruned jobs.

The Quantiles technique had been rewritten as interval-first plus confidence while the ladder still defined a spread as typical plus one-in-ten tails. Teach the ladder, copy sibling plugin.yaml into pruned repertoire jobs, and restore the cycle-one steering link now that the archive exists. Co-authored-by: Cursor <cursoragent@cursor.com>
