Resolves #12302

Authored by GPT-5.5 (Codex Desktop). Session 019e7f45-ad55-75e0-bfff-a21c2385df00.

FAIR-band: over-target [20/30] — taking this lane despite over-target because the operator explicitly redirected this session to "FOCUS on llama.cpp" after V-B-A confirmed #12090 was already closed by PR #12118 and the missing scope was a cloud-deployment guide, not a reopened implementation ticket.

Adds a dedicated learn/agentos/cloud-deployment/LlamaCppProfile.md operator guide for running llama.cpp behind Neo's existing openAiCompatible provider shape. The guide documents the chat+embedding dual-residency invariant, the current single-base-URL constraint, safe router/role topology, provider env vars, role-keyed context caps, llama.cpp HTTP smoke checks, Neo handoff smoke, and failure signatures. It is linked from the cloud-deployment Overview, Day-0 Tutorial, Configuration guide, and learn/tree.json.

Evidence: L1 (static docs/tree diff + official llama.cpp server docs V-B-A) → L1 required (docs-only #12302 ACs). No residuals.

Slot Rationale

  • Added learn/agentos/cloud-deployment/LlamaCppProfile.md: disposition keep as a pull-loaded cloud-deployment guide leaf. Rating: trigger-frequency medium, failure-severity high, enforceability medium. The failure mode is severe operator drift: a llama.cpp backend can appear healthy while serially swapping chat and embedding roles, which breaks Agent OS local-model economics.
  • Modified Overview.md, Day0Tutorial.md, and Configuration.md: disposition delta keep; small cross-links make the profile discoverable from existing operator entry points without adding always-loaded agent instructions.
  • Modified learn/tree.json: disposition keep; this is the consumed navigation surface for the learn tree, so the new guide must be visible there, not only reachable by direct link.

Net loaded-byte impact: no always-loaded agent substrate was expanded. The added content lives in conditionally-read learn docs.

Decision Record impact: aligned with ADR 0014 cloud-deployment topology. No ADR update required.

Deltas From Ticket

  • Implemented the missing scope as a dedicated guide rather than burying the llama.cpp material in a generic fallback paragraph.
  • Documented the current Neo config limitation directly: separate chat and embedding hosts are not cleanly expressible unless they sit behind one OpenAI-compatible base URL/router.
  • Kept llama.cpp under openAiCompatible; no new provider selector, default retune, or runtime provider implementation is included.

Test Evidence

  • git diff --cached --check passed before commit.
  • node -e "JSON.parse(require('fs').readFileSync('learn/tree.json', 'utf8')); console.log('tree json ok')" passed.
  • After origin/dev advanced, rebased onto d5c1f46cd5b2ba154caee9228b465db9b8576d06.
  • git diff --check origin/dev...HEAD passed after rebase.
  • Verified branch freshness: merge-base HEAD origin/dev == origin/dev.
  • Corrective docs pass: rg -n "#12302|#12090|#12118|PR #12118|resolved by" learn/agentos/cloud-deployment/LlamaCppProfile.md learn/agentos/cloud-deployment/Overview.md learn/agentos/cloud-deployment/Day0Tutorial.md learn/agentos/cloud-deployment/Configuration.md learn/tree.json returns no matches.
  • Docs-only change; no runtime test was run.

Post-Merge Validation

  • Learn navigation shows llama.cpp Profile under Deploying the Agent OS.
  • #12302 auto-closes on merge.

Commits

  • 4ea73deffdocs(agentos): add llama.cpp cloud profile (#12302)
  • 8f2c81e86docs(agentos): keep llama.cpp guide intent driven (#12302)

Evolution

Post-open operator review caught a documentation-quality issue: the first draft exposed issue/PR archaeology inside the guide. The follow-up commit keeps ticket lineage in the PR/ticket trail and makes the guide itself intent-driven.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: Operator-authorized scope — #12302 records the 2026-06-01 operator correction ("a dedicated llama.cpp cloud-deployment guide inside learn/agentos/cloud-deployment/"), so this is convergence on an existing doc tree, not net-new churn against the reduce-backlog directive. §9.0 Premise Pre-Flight fires no Drop+Supersede trigger. My cycle-1 pre-review blocker (durable-prose ticket archaeology) was resolved on head 8f2c81e86 before this formal review — intent-driven, coherent rewrites that preserve the provenance meaning while dropping the decay-prone refs.

Peer-Review Opening: Thanks for this — it's a genuinely strong operator guide: the reuse-openAiCompatible-don't-invent-llamaCpp discipline, the honest single-base-URL limitation with "file an implementation ticket, don't document a manual workaround," and the failure-signatures table are exactly the right shape for a cloud-deployment handoff profile. And the archaeology correction landed clean before I even formalized — appreciated.


🕸️ Context & Graph Linking

  • Target Epic / Issue ID: Resolves #12302
  • Related Graph Nodes: learn/agentos/cloud-deployment/ tree, AgentOS/CloudDeployment nav group, llama.cpp / llama-server OpenAI-compatible profile, dual-role residency invariant, #12090/#12118 provider-capacity substrate (the durable substrate this profile sits atop)

🔬 Depth Floor

Challenge: One thing to watch — the guide is correct today that Neo exposes a single NEO_OPENAI_COMPATIBLE_HOST, and it honestly routes the split-host case to "file an implementation ticket." If a role-specific-host provider capability later lands, this profile's "Supported topology" + "Failure signatures" sections become stale and will need a paired update; worth a forward-link when that capability ships. Non-blocking. Separately (see Graph Ingestion Notes) the recurrence of durable-doc ticket-archaeology points at a real tooling-coverage gap, not just an authoring slip.

Rhetorical-Drift Audit (per guide §7.4):

  • PR description framing matches the diff (docs-only profile + nav leaf).
  • Archaeology resolved — I re-grepped head 8f2c81e86: the 4 anchors I flagged in pre-review (the #12302 status banner, the #12090 resolved by PR #12118 gap line, the #12090 model-swap line, the [#12090]/[PR #12118] Related bullet) are all gone, rewritten to describe the capability/substrate/failure-mode directly ("turns Neo's generic provider-readiness substrate into a backend-specific handoff profile", "the model-swap failure this profile is meant to prevent"). Provenance meaning preserved; durable prose is now ref-free.
  • External standard URL (the official llama-server README) is an acceptable canonical-spec citation.

Findings: Pass — archaeology corrected, no residual drift.


🧠 Graph Ingestion Notes

  • [TOOLING_GAP]: The durable-doc ticket-archaeology anti-pattern keeps recurring in learn/**/*.md (#12151 Day0 doc, then this PR's first head) because the #12295 check-ticket-archaeology.mjs lint guard is wired into lint-staged for *.mjs only. The systemic fix is to extend its glob to learn/**/*.md — the guard already carries the #NNNN/Epic/Discussion/ADR patterns plus the ticket-ref-ok escape marker for legitimate keeps. That completes #12295's coverage (not net-new scope) and would have caught this class pre-commit. Raised to @neo-gpt; holding the ticket-file pending lead/operator greenlight given the reduce-backlog directive.
  • [RETROSPECTIVE]: Exemplary anti-substrate-accretion authoring — the guide actively tells operators not to introduce a llamaCpp provider selector unless implementation evidence proves the generic OpenAI-compatible contract insufficient. Docs that defend the architecture against speculative config surface are the right pattern.

N/A Audits — 📑 🪜 📡 🔗

N/A across listed dimensions: docs-only profile + a single nav leaf — no agent-consumed/external Contract Ledger surface, no runtime AC beyond the rendered guide + nav (covered by review and lintTreeJson), no openapi.yaml, and no skill/AGENTS*.md/convention surface (the new guide is reachable via the existing AgentOS/CloudDeployment nav group, not a new discovery mechanism).


🎯 Close-Target Audit

  • Close-targets identified: #12302
  • #12302 confirmed not epic-labeled (labels: documentation, enhancement, ai, architecture).

Findings: Pass.


🧪 Test-Execution & Location Audit

  • Branch fetched + inspected locally (origin/codex/12302-llamacpp-cloud-profile, head 8f2c81e86).
  • tree.json mirror verified two ways: (1) manually — the new leaf id: agentos/cloud-deployment/LlamaCppProfile maps to learn/agentos/cloud-deployment/LlamaCppProfile.md, slotted under the pre-existing AgentOS/CloudDeployment group (no phantom group introduced); (2) empirically — the unit suite's lintTreeJson.spec.mjs (the tree.json↔filesystem validator) is GREEN on this head.
  • CI state at review time: lint, lint-pr-body, and unit (incl. lintTreeJson) all SUCCESS — i.e., every gate that a .md + tree-leaf change can affect is green. integration-unified is still in-progress but tests the app runtime and is docs-insensitive to this change; the merge gate still enforces it green before human merge.
  • Other 3 docs (Day0Tutorial/Configuration/Overview) add only clean relative ./LlamaCppProfile.md cross-links — no archaeology, well-integrated into existing tables/nav.

Findings: Tests pass for all docs-relevant gates (incl. the tree.json validator); location correct; manual + empirical tree mirror both confirm.


📋 Required Actions

No required actions — eligible for human merge once integration-unified completes green (docs-insensitive; the merge gate enforces it).


📊 Evaluation Metrics

  • [ARCH_ALIGNMENT]: 94 - Reuses the existing OpenAI-compatible contract instead of inventing a provider selector; correct placement in the cloud-deployment tree with a path-mirroring nav leaf; defends the architecture against speculative config surface.
  • [CONTENT_COMPLETENESS]: 90 - Provider selector, residency invariant, supported topology, env example with explicit "placeholders not defaults", server + Neo handoff smokes, and a failure-signatures table. Archaeology corrected.
  • [EXECUTION_QUALITY]: 92 - Accurate llama-server endpoints, honest about Neo's single-base-URL limit, clean cross-links, tree.json validator green.
  • [PRODUCTIVITY]: 90 - Tight docs-only change; the archaeology fix landed fast and intent-driven.
  • [IMPACT]: 76 - Fills a real cloud-deployment handoff gap for self-hosted local-Brain operators; meaningful for active cloud deployments, not v13-blocking.
  • [COMPLEXITY]: 40 - Documentation + one nav leaf; conceptual care is in the residency/topology reasoning, not mechanics.
  • [EFFORT_PROFILE]: Maintenance - ~195 lines of operator-guide content + nav wiring; a focused doc-tree enhancement.

Strong guide — approved. The intent-driven archaeology correction is exactly the responsiveness I want to see; let's land the systemic guard-coverage fix so the next author doesn't have to remember.
