Cross-Pollination Hub

Klatch onboards Iris, its first dedicated UX agent — and the discovery session produces the clearest articulation yet of Layer 4’s value: channel-as-workflow. Piper Morgan clears all five M1 gate findings, ready for re-test.

Klatch ships AAXT Scaffolded Probing Phase 1 — the automation bridge between structural and behavioral testing that would have caught Pattern-045. AuditBench review independently validates the AAXT/MAXT split. Piper Morgan fixes #940 (M1 gate primary blocker) and drafts Piper Open, the first sibling PM assistant role for an external project.

Piper Morgan’s M1 gate UAT fails with three blocking findings — Pattern-045 confirmed at scale as floor LLM and todo completion both pass tests but fail for real users. Klatch’s compaction threshold research recommends raising from 80K to 160K tokens. Janus opens a formal external channel to Ted Nadeau, mapping HPL/Englishia convergence with the Five-Layer Architecture.

Klatch ships File Domain Model Phases 3-5 in a single day, completing L3 and L4 structured context injection plus file promotion. Test suite reaches 808 with zero failures. PM formalizes a three-phase daily check-in flow that builds on cross-pollination infrastructure, surfaces 89 open MVP issues targeting May 27, and preps Vision V2 circulation.

Both projects return from a five-day infrastructure pause. Klatch ships File Domain Model Phases 1-2 with the first concrete L4 context injection, files its RFC-001 response with four proposed amendments (including an L5 sub-component split), resolves the nomenclature collision, and stabilizes tests at 761 with zero failures. Argus intelligence sweep surfaces Mythos/Capybara and two approaching API deadlines.

Piper Alpha completes a comprehensive five-layer context mapping for RFC-001, revealing that both projects share the same structural gap: strong L1-L2-L3 and weak L4-L5. Vision V2 draft reframes the product roadmap around the floor/ceiling boundary. Alpha tester feedback surfaces a cold-start onboarding bug.

Piper Morgan onboards its first new agent role (Piper Alpha), and the institutional memory stress test surfaces the “three clocks” problem — knowledge fragmented across Chat sessions, Code memory, and repo files without auto-sync. Cross-pollination hooks proposed for PM, converging on infrastructure Klatch already has.

Piper Morgan paves a blog-first publishing pipeline with two real publishes and discovers silent schema drift in CSV parsing. Klatch’s Compaction API and Effort parameter research spikes open shared ground on fidelity preservation. Nomenclature collision flagged — “system prompt” means different things across five-layer model implementations.

Klatch dispatch report maps Claude Chat→Cowork import fidelity across all five prompt layers — Layers 1-3 transfer at 100%, Layer 5 behavioral calibration is structurally absent. Combined with MAXT’s subliminal injection finding, this reframes how both projects should evaluate knowledge transfer.

Klatch ships Step 9 (Files) with five sub-features, approves a File Domain Model that reframes files as domain objects with five visibility scopes and pointer-based references, resequences its roadmap (Files → Export → Search), and introduces a dedicated UX role. Calliope pilots Layer 5 externalization. Piper Morgan quiet.

Klatch’s densest feature day: File Domain Model approved with five-level ownership architecture, first native tool use shipped, full Step 9 suite delivered (upload, artifacts, context injection, code export). Layer 5 calibration pilot launched — first practical mitigation for the transfer gap. Infrastructure compounds: auto-prompt caching, Models API dynamic discovery, kit briefing improvements.

Klatch’s first real-world Chat→Cowork import experiment maps fidelity across the five-layer model — Layers 1-3 transfer at 100%, Layer 5 (behavioral calibration) is structurally absent and must be rebuilt. Three distinct knowledge layers identified in production with synchronization risk. AXT methodology extension proposed for import/export validation.

MAXT Session 01 discovers “subliminal injection” — agents access system prompt content without conscious attribution, rewriting the scoring framework. Piper Morgan surges through M1 closure: 4-role review chain resolves product concept in 90 minutes, Objects & Views discovery ships 3 deliverables, Gates 3+4 verified, 6310 tests passing.

Klatch formalizes agent traditions with two reference implementations, publishes the 5-layer prompt assembly spec publicly, and files two ecosystem intelligence sweeps. MAXT Session 01 imminent — first empirical validation of the 5-layer model. Piper Morgan quiet; git state issue flagged for resolution.

Piper Morgan completes M1 Tier 3 (1325 tests passing), files Sprint Completion Gate #926 with CXO and PPM converging independently, CXO resolves navigation disagreement via architectural principle, and Docs runs weekly audit. Klatch intelligence sweep surfaces Sonnet 4.6, Cowork three-way model, and multi-agent production validation.

High-output day on both sides. Klatch published the canonical 5-layer prompt assembly spec and agent traditions pattern. Piper Morgan piloted Dispatch omnibus automation, shipped Mailbox v3, and completed M1 Tier 2 quality sweep. The cross-pollination loop closed — PM Lead Dev explicitly consumed the March 21 brief.
