A ContextReporter wired into subagent sessions lets the read tool advertise the
files it reads (≥10 lines) on its job board entry, so a completed specialist
shows what it already looked at. Root sessions report nothing (no parent board).

The `task` tool delegates to a SubagentSpawner (owned by the composition root):
resolves the agent, enforces the depth limit, applies permission intersection,
filters tools per-agent, and runs the child session foreground or background.
Foreground returns the child's final text; background registers on the job board
and detaches under the parent run token. The run loop injects the board into
primary-agent requests and reconciles terminal jobs each step.
Integration tests cover foreground run + alias reuse continuing the same child
session, depth-limit and unknown-agent rejection, and board prompt injection.

Direct port of ~/repos/opencode/packages/opencode/src/tool/edit.ts: the
9-stage replacer chain (Simple, LineTrimmed, BlockAnchor, WhitespaceNormalized,
IndentationFlexible, EscapeNormalized, TrimmedBoundary, ContextAware,
MultiOccurrence), Levenshtein-based block-anchor similarity, and the
disproportionate-match guard that hard-stops rather than falling through to
the next candidate. Also ports edit.test.ts's scenarios: new-file creation,
BOM preservation, CRLF handling, replaceAll, directory/not-found/identical
errors, loose block-anchor rejection, and concurrent edits to the same file
serializing through a per-path tokio::Mutex without losing either change.
99 tests passing across the workspace, clippy clean. This lands the last
of the six M1 built-in tools (read/write/edit/bash/glob/grep).
Five of the six M1 built-ins (edit's replacer chain is a separate port).
bash uses process_group(0) + SIGKILL-the-group on timeout/cancel; glob/grep
are gitignore-aware via ignore::WalkBuilder and don't ask permission
(read-only); read/write/bash ask through ctx.ask with opencode's coarser
"always" pattern (first word + wildcard for bash, path for edit/read).
Wired tool output through the central 30k-char truncate() in the processor
so every tool gets spill-to-disk behavior for free. 70 tests passing,
clippy clean.
Seven-crate workspace per docs/01-architecture.md. harness-core gets the
domain types (Session/Message/Part/ToolState), a broadcast EventBus, the
last-match-wins wildcard permission evaluator, and a SQLite storage actor
(dedicated thread + mpsc, JSON-blob rows) with roundtrip tests. All other
crates are compiling stubs. CI runs fmt/clippy -D warnings/test.
