Module providers 

M.6 (2026-06-01) onwards: in-tree multibuffer providers.

Each provider is one user-facing surface (project-search, lsp-references, project-diff, etc.) built on top of the multibuffer machinery. Provider code lives in this crate per the 2026-06-01 architecture decision (multibuffer-views.md §3.7), behind individual cargo features:

• search — providers::search, the worked SearchProvider example. Walks the filesystem via ignore::Walk, matches literal queries (regex landing in a follow-up), streams batches via typed ProjectSearch* events.

Each provider declares: a service trait + handle, typed events for its scan / fetch lifecycle, a minor mode contributing provider-specific keymap + lifecycle subscriptions, a public trigger function, and a boot helper that wires the service into ServiceRegistry + registers the mode against ModeRegistry.

Modules

clock_report

OA.16: clocked time, rolled up an outline — the report scan-view-clockreport-mode renders over any scan view whose source reports clock spans. OA.16 — the clock report: clocked time, rolled up an outline.

narrow

N.1.1 (2026-06-10): narrow mode — a focused, editable one-excerpt multibuffer view of a region. Unlike search, narrow is a first-class built-in (no cargo feature gate): no async scan, no service, no per-view state beyond the excerpt. N.1.1 (2026-06-10): narrow mode — a focused, editable one-excerpt multibuffer view of a region of a source buffer.

plugin_view

CM.4 (2026-07-22): the *problems* view — the current error list grouped as editable source excerpts by file. Like narrow, a first-class built-in (no cargo feature gate): the entry list is static, so no async scan / service / per-view state. MV.1b — the generic provider behind every plugin-owned multibuffer view.

problems

CM.4 (2026-07-22): the *problems* multibuffer view — the grouped, editable “problems” surface for the error list.

scan_view

OM.A1 (2026-08-25): the *agenda* view — every dated row that plugin scanned-excerpt-source producers find under the project root, globally ordered and date-grouped, as editable source excerpts. Feature-gated like search because it pulls the ignore walker. OM.A1 (2026-08-25): the agenda provider — a date-grouped multibuffer of rows contributed by plugin scanned-excerpt-source producers.

search

M.6 (2026-06-01): SearchProvider — the worked MultibufferProvider example.
