2.0.0-rc.6: Lauren's 99743e9, marginal sections cut from four skills

[chhoumann]

t3-pstack moves to Lauren Tan's pstack at cursor/plugins 99743e9 for all three components. Only pstack changed upstream, in one commit, and its version stays 0.15.25:

• pstack #634: four skills lose marginal sections, and the change only deletes text. interrogate's references/lead-judgment.md drops its preamble and Verdict Calibration. principle-type-system-discipline keeps three of its eight rules, and its description drops "refuse to lie to the compiler". principle-migrate-callers-then-delete-legacy-apis drops its intro, three of its four rules, and its closing line. swarm drops its intro line, Phase A step 3, and one Phase C sentence. Its README change falls under a path tools/upstream.json excludes.

This is Lauren's text plus mechanical version lines, with two substitutions removed because upstream deleted their targets. No other rule or fork changed. The port's diff to the four skill files is upstream's line for line, apart from the T3 form of the two deleted swarm lines those rules wrote.

Removed substitutions

Both rules had no files scope, and both rewrote a swarm line that #634 deletes, so at 99743e9 neither matches anything in any component:

• "Fan out N parallel cloud workers." to "Fan out N parallel workers." (swarm's intro line).
• "not the cloud concurrency limit." to "not the number that run at once." (swarm's Phase A step 3).

Commits

1. Sync. With the two rules removed, sync.mjs derives the old side (e5136d8) without them too, so swarm's merge base no longer matched the port and the three-way merge conflicted on an undeclared path. pstack therefore ran through bun tools/sync.mjs pstack 99743e9 --bootstrap, which derived 120 files, kept the 13 declared forks, and changed only the four files upstream touched. cursor-team-kit and thermos synced normally with no file changes. All three pins now read 99743e9.
2. Release. VERSION and the manifests move to 2.0.0-rc.6. CHANGES gets the entry with its behavior-delta table. NOTICE, NOTICE-skills, and the README point at 99743e9.

On T3

swarm keeps every T3 dispatch anchor. Phase A step 4 still reads the swarm workers line in the model sheet, falls back to the default in its Models section, omits target for auto or inherit-parent, and falls back within a family through orchestrator_capabilities. Upstream kept that step numbered 4 after deleting step 3, so Phase B's "delegate_task calls with mode: "async" and the step 4 target" still names it. The per-worker worktree rule and the Models stamp are untouched. With step 3 gone, nothing defines N beyond the description, which is upstream's choice and carries no T3 text.

interrogate's T3 dispatch lives in SKILL.md, which #634 leaves alone: Step 3's delegate_task per interrogate reviewers entry with role: "review", the reviewer table, the family fallback, and the Models stamp. No rule touched the deleted lead-judgment.md text. Step 5 still casts the lead as a pragmatic engineer, not a neutral aggregator, and points at lead-judgment.md, which now opens at its filtering principles. The two-family panel lives in models.json's panel tier, enforced by generate.mjs and t3-sheet.mjs, and thermos reads the first two families of the interrogate reviewers line. None of that moved.

poteto-mode's index entry for Type System Discipline never quoted "refuse to lie to the compiler". It matches upstream's entry at 99743e9, which #634 did not touch, so it stays. No port-only file quotes any deleted text.

Checks

• bun tools/sync.mjs <component> 99743e9 --dry-run for pstack, cursor-team-kit, and thermos: exit 0, no undeclared fork, no denylist hit, no unmatched substitution. At the pin, pstack reads 120 unchanged files and the same 13 declared forks with 469 changed lines as before.
• bun tools/generate.mjs --check: 17 generated files current, and the hooks freeze check passes. Neither hooks file differs from origin/main.
• GIT_CONFIG_GLOBAL=/dev/null bun test tests/ --timeout 30000: 537 pass, 46 skip, 0 fail.
• Scripts: bun run typecheck, bun test orch watch-pr check-plan.test.ts (119 pass), and the Prettier check all pass.
• t3-sheet.mjs against this machine's sheet and catalog: every role line parses and dispatches.

Note

Low Risk
Upstream skill text deletions and version/sync metadata only; T3 dispatch rules in swarm and interrogate SKILL.md are untouched.

Overview
Release 2.0.0-rc.6 syncs t3-pstack to Lauren Tan's upstream pstack at cursor/plugins 99743e9 (pstack #634): four skills are trimmed by deleting redundant sections only—no new behavior in those files.

interrogate lead-judgment.md loses its opening framing and Verdict Calibration. principle-type-system-discipline keeps three rules (brand primitives, parse at boundaries, derive from schemas) and drops five others plus "refuse to lie to the compiler" from the description. principle-migrate-callers-then-delete-legacy-apis keeps the test-update rule and applicability bullets; intro, three rules, and the dual-path closing are removed. swarm drops its intro, Phase A step 3 (setting N), and one Phase C aggregation line; T3 delegate_task / worktree wording is unchanged.

Port tooling: tools/upstream.json pins all three components to 99743e9. Two entries in tools/substitutions.json are removed because upstream deleted the "cloud workers" lines they rewrote. CHANGES.md, NOTICE*, and README record the bump and new pin; version manifests move to 2.0.0-rc.6.
