rdmsm4x-changelog-20260827-1603-litellm-mem0-ollama-boundary

Recorded independently reproduced Mem0/Ollama authority and dependency identities in LiteLLM documentation so future routing work preserves the separate memory plane and cannot treat proposed aliases as configured.

Scope

• Host: rdmsm4x
• Canonical project: /Users/richh/dev/localAI/litellm
• Isolated worktree: /Users/richh/dev/_worktrees/codex-litellm-qa-agent-20260827
• Branch: codex/litellm-qa-agent-20260827
• Commit: eb15041c7dcd73803e68e0366a8e9da27285da72
• Source coordination task: 01a0409d-475e-7ee1-bfa9-4a0f536ff9fe
• Privacy: metadata only; no credentials, prompts, responses, Mem0 records, model blobs, or retired-worktree contents accessed

What changed

• Recorded accepted Mem0 authority as Compose project mem0-local from the clean Mem0 task worktree at commit 7079ac107ff2f3c9a3cf187c2bec9f5656cf24e1.
• Recorded the competing Compose project mem0local as retired and preserve-only, with zero containers and zero project networks.
• Recorded exact loopback boundaries: LiteLLM 127.0.0.1:4000, Mem0 API 127.0.0.1:8767, Ollama 127.0.0.1:11434, and no Qdrant host port.
• Recorded exact Ollama model identities for the Mem0 reasoner and 2,560-dimensional embedder.
• Added LITELLM-014 to keep local-memory-reasoner and local-memory-embedding-2560 blocked and unconfigured until explicit approval plus separate chat/embeddings capability, resource, restart, failure, and rollback canaries.
• Preserved the rule that clients call Mem0 separately and LiteLLM never proxies Mem0, copies its credential, ingests memory automatically, or acts as a prompt/query cache.

Commands and verification evidence

• Resolved the host with scutil --get ComputerName: rdmsm4x.
• Synced fleet check-ins and inspected released LiteLLM ownership before writing.
• Reproduced Git authority with git rev-parse, branch, and porcelain status checks:
  • canonical LiteLLM main remained clean at 74caa92e3bacae28b33d61cd16140204099ad70a;
  • isolated LiteLLM branch began clean at aceaf5389ef82255c7749bb3fa28555feb6f6af3;
  • accepted Mem0 worktree was clean at 7079ac107ff2f3c9a3cf187c2bec9f5656cf24e1;
  • retired Mem0 worktree remained at d56c3d5440221f4597e22aee7826305e896d4444, with no tracked delta and 20 untracked file entries under fully expanded status.
• Queried Docker name/status/port metadata only; mem0-api, mem0-qdrant, and litellm-loopback-canary were healthy. The retired Compose project had zero containers and zero networks; its preserved named volume remained present.
• Queried non-secret loopback health/model metadata only:
  • LiteLLM health HTTP 200 and model list exactly agent-local;
  • Mem0 health ok, mem0_shared_v1, 2,560 dimensions, the recorded reasoner/embedder, and explicit-literal capture;
  • Ollama 0.33.1, exact dependency digests present, neither dependency resident.
• zsh tests/validate-static.zsh: 60 checks, zero failures.
• zsh tests/validate-qa-static.zsh: 10 checks, zero failures.
• python3 -m unittest tests.test_qa_agent: 6 tests, OK.
• Documentation integrity/path guard and git diff --check: passed; only the three intended Markdown files changed before commit.
• gitleaks detect --source . --no-git --redact --no-banner: no leaks found.
• The runtime-mutating rollback suite was deliberately not run because it requires stopping the accepted live canary and this coordination pass authorized no runtime mutation.

Backups and rollback

• No pre-existing file was overwritten outside the isolated Git worktree; Git commit eb15041c7dcd73803e68e0366a8e9da27285da72 is the recoverable change boundary.
• To undo only this documentation alignment, revert that commit on branch codex/litellm-qa-agent-20260827 after confirming no later dependent commit.
• Do not delete the retired Mem0 worktree or its preserved named volume as part of rollback.

Outstanding owner actions

• Decide whether the two proposed model identities should ever be LiteLLM aliases or remain direct Mem0/Ollama dependencies.
• Any implementation still requires explicit approval and the LITELLM-014 canary gates.
• The isolated LiteLLM branch remains unmerged; no push or canonical-main integration occurred.
• Apple Notes mirror remains pending because the shared publisher's documented deletion/count hazard has not been cleared; this Markdown file is the durable archive.
