This PR is an isolated Contribution Manager pilot mirror. Its reviews, checks and merge state are separate from upstream. An empty [skip ci] commit suppresses automatic bulk CI; the code tree matches the imported upstream revision.

Opencode sessions never got an intelligent title — every new thread fell back to truncating the prompt. Two stacked causes, two commits:

1. Opencode: title runs from the session harness (harness)

• supports_titles excluded OpenCode, so the engine failed over to another harness (often unauthed) and gave up.
• OpencodeHarness::run_title added: request sanitized (no resume/worktree/attachments/MCP/model options, no auto-approve), title_only threaded through Session/BusCtx so permission.asked replies reject instead of once. Questions still resolve empty and never block.
• Live proof vs real opencode server: check why the login redirect loops on staging → Staging Login Redirect Loop, Completed, zero tool calls.
• Test: title_runs_reject_tool_permissions (v1+v2 fixture).

2. Engine: title follow-the-session with the session's own model (engine)

• The titler received the harness but never the model, so it guessed cheapest-catalog — catalogs list models the account can't call, and the guess burned all retries.
• request.model is threaded through maybe_generate/generate/run_title_model; with nothing pinned and the title on the session's own harness, its model is reused. Cross-harness titles keep the catalog guess; pinned settings win as before.
• Test: session_model_is_reused_for_same_harness_titles.

How to verify: new opencode thread with Thread naming on follow-the-session → 3–5 word title within ~15s; grep -i auto-titl data/logs/zeron-headed.log.

Suites: engine titles 5 passed; harness lib incl. all 61 opencode tests, claude (16), codex (27) green — one pre-existing timing flake (stalled_prompt_post_has_a_bounded_timeout) fails on pristine main too. rustfmt --check clean; no new clippy warnings. Supersedes zeronsh#611 and zeronsh#613 (closed).
