Give durable user context its producer-owned source kind instead of a generic plugin wrapper. The V3-to-V4 conversion preserves the frozen rename and collision rules, all own JSON metadata, event coordinates, and historical request-only kinds. Native catalog and JSONL admission retain source validation so unknown attribution can survive without its producer while malformed owned sources are refused.
Use an explicit user-only RequestUserInput for auxiliary LLM prompts that do not own durable message identity. Auto Review and compaction remove their request-only source registrations while retaining prompt content and freezing; provider serializers and projections keep the same wire data, assistant replay isolation, image ordering, and tool correlation. Session writes, Agent delivery, and recorded title requests continue to require identified durable messages.
Bind the saved compatibility policy only to user sources and qualify tmux location attribution without weakening fixed system, model, or tool semantics. Rebuild the current inventory and unpublished V4 acknowledgement on the actual tool-role parent, preserving its rationale and all accepted historical records. The catalog format version records tooling metadata; Session remains V4. Developer-role policy and activation belong to their own feature.
The latest-master Messages adapter, serialization, request-input typing, EpochHeader reservation, and attribution checks pass 103 tests across five files. The retained V3 Messages input-history snapshot passes through the source profile; Host/Client typechecks and all 41 documentation gates pass. The generated comparison records four changed roots and 447 unchanged type fingerprints. Latest-master ARIA changes are retained, with producer source labels applied independently; new Messages fixtures retain their producer names as declared source kinds and use the fixed system-message helper; recorded Session generations are unchanged by this regrouping.

Render reconstructable system prompts at each request-series boundary, preserve series declarations through pre-step wrappers, and keep the presentation and replay snapshots aligned across clients.
- user-approval: name the absent agent loop when the turnBoundary
projection is not registered (instead of the misleading 'outside an
open turn') and declare dsh-agent-loop as a peer dependency; add a
regression test for the missing-unit composition (v4p).
- session-title / time-context / agent-instructions: converge the
self-registered-key-absent handling to a loud throw with the same
v8-ignored comment style (v5 suggestion).
- llm-retry: validate config before registering the projection unit;
document the branded-retry-id zod cast; start stateVersion at 1.
- agent-loop: register turnBoundary only after every config validation,
so a rejected constructor leaves no unit behind; the defensive-cap
test no longer needs fiber cleanup.
- agent-instructions: keep newest-first per-scope change history so the
latest visible change survives a surface replacement shadowing the
newest one (restores the previous scan-visible semantics); add a
regression test for the delete-after-shadow sequence.
- tool-skill: keep catalog-message history so a shadowed newest catalog
message still falls back to the latest visible digest.
- session-query-sqlite: drop the unused required sessionProjections
injection.
- plan-mode: restore the command/done error-drop regression test and the
cold-replay command/done fold; drop the inaccurate state-reference
comment.
- tool-todo: remove a stray blank line; document the turnBoundary
reader contract on the projection type.
