Orphan Bridge Protocol — a dream cycle that must mutate the graph

The new GBrain Deep Dream cron (job a10859e31884, 3 AM nightly) is built on a single principle: every phase ends in a brain_put_page call, not a markdown file. This page is the architecture.

Why this exists

The prior GBrain Dream Cycle (job 63c0e210882f) had been producing detailed six-phase reports every night for weeks without moving the orphan rate off 97.9%. Diagnosis: the prompt used description verbs ("scan", "report", "summarise") and zero action verbs that touch the graph. See 2026 05 23 The Report Not Write Loop A088c6 for the failure mode. The new protocol fixes the verb shape.

The six phases

Each phase has a must-write gate. If the gate isn't met, the phase fails and is retried.

Phase 1 — Conversation Harvest

Scans today's transcripts for new entities, beliefs, decisions. Output: brain_put_page calls to create stub pages for novel concepts (or update existing pages if the slug already exists).

Phase 2 — Stub Creation

For each new entity harvested in Phase 1, create a real page with at least one cross-link. Stub pages without links are themselves orphans — creating them makes the problem worse, not better.

Phase 3 — Orphan Bridge Protocol (the core phase)

The 50-100 most valuable orphans get explicit bridging links to existing hub pages. This is where the metric moves. Targets by category:

• People pages → link to relevant project pages and vice versa
• Project pages → link to methodology pages, theory pages
• Concept pages → link to first-order applications and back-references
• Hub pages (people/nathan-maxwell, concepts/gbrain, etc.) → absorb orphans

by topic cluster

Each orphan must get at least one incoming link to count. Output: brain_put_page calls against the target page (the hub), not the orphan itself, because that's where the link surface lives.

Phase 4 — Memory Consolidation

For related topic clusters (e.g., all swim-coaching pages, all GBrain operational pages), produce a synthesis page that links them together. This is the gbrain equivalent of a /concepts index page in a traditional wiki.

Phase 5 — Contradiction Detection

Walk beliefs and check for direct conflicts. If belief-A says "X is true" and belief-B says "X is false," produce a reflections/ page that names the contradiction and links both. The dream cycle is the right surface because it has read access to everything; humans don't.

Phase 6 — State File + Summary

Write a summary to dream-cycle-summaries/<date>.md only after Phases 1-5 have produced measurable writes. The summary is the receipt, not the deliverable. Update dream-cycle-memory.json with orphan count delta, links-created count, pending work for next run.

The design rules, with rungs

• Action verbs in the prompt, not description verbs. "Phase 3 must call

brain_put_page ≥ 50 times" beats "Phase 3 should create meaningful bridges." The number is the contract. Compare to the ponytail ladder's rung recognition in 2026 07 07 Ponytail Ladder Emerges 1c6aaa.

• Memory across runs. dream-cycle-memory.json carries state forward.

Each night knows what it did last night and what it should target tonight. This is the difference between a stateless report and a memory system.

• State mutation > state description. Inspired by the same architectural

finding as 2026 05 22 Gbrain Skills And Timeline Shape 44b0c7: silent zeros and silent non-mutations both look like progress until you audit the actual graph.

• Skillpack-aligned. The companion gbrain-enhancement skill (analogous

to 2026 07 07 Voice Transcribe Skillpack 1c6aaa in shape) is the operational documentation: Garry Tan's 8-layer memory architecture as the conceptual scaffold, Orphan Bridge Protocol as the action surface.

What was deliberately skipped

• Bidirectional GBrain ↔ Obsidian sync. Not in this protocol. The

vault-sanitiser already wires Obsidian Wikilinks into GBrain at 2 AM. Reverse direction would require writing back to Obsidian from a dream cycle, which crosses a trust boundary (the vault is the human's source of truth). Flagged as future work; see 2026 05 22 Gbrain Skills And Timeline Shape 44b0c7 for the ingest-side architecture that would need to be paired.

• Contradiction resolution (Phase 5 deep mode). Detection only this round.

Resolution requires user input (which belief wins?). Surface as a reflection page in the morning, not auto-merge.

• Auto-merge of near-duplicate pages. Tempting but dangerous. Two pages

that look similar may have been intentionally separated (e.g., one is a daily reflection, one is a concept). Leave to explicit user action.

First-day validation

Day-1 of this protocol produced 20 real links across:

• people/nathan-maxwell ↔ projects/hydrolyze, people/aidam,

people/adam-maxwell, concepts/gbrain-agent-memory

• concepts/nathan-taste-profile ↔ swim coaching methodology, podcast
• concepts/hydrolyze ↔ training-load spec
• concepts/deliberate-practice-cognitive-load ↔ concepts/gbrain-agent-memory

(embodied — same philosophy)

• Swim training pages ↔ concepts/deliberate-practice-cognitive-load

Plus three new hub pages: people/nathan-maxwell, concepts/gbrain-agent-memory, concepts/gbrain-deep-dream. Hub pages are link sinks by design — they absorb orphans by topic cluster over time.
