Moving the task registry to the host plane put every preset's `tool-tasks`
listener on ONE `LocalTaskService`. `settle()` computes a single snapshot and
walks every registered listener with no scope filter, and it marks `reported`
only when a waiter is present — so a task settling without a waiter reached
each mount's listener with `reported` false and every one of them injected the
same completion into the same owner. Three shipped presets carry `tool-tasks`,
and a preset file edit adds a second generation of the same mount, so an agent
read N copies of one notice as model-visible durable context.
A mount now claims an owner only when the owner's scope chain reaches the
mount's own scope. An unscoped mount is the host-plane instance that serves
every agent, which keeps the TUI composition and every existing test intact.
Registry-side ownership was the alternative: mark `reported` once the first
listener claims it. It is wrong because `onTaskDone` is not a notice-only
seam — the `dsh-tasks` invariant companion registers a validating listener —
so first-claim-wins would silence observers that are not delivering anything.
The regression test mounts two scoped `tool-tasks` over one registry and
settles an unowned-wait task, which is the only path that reaches the notice
listeners at all: the shipped-composition e2e uses `wait: true`, and a waiter
marks `reported` before settlement, so that test structurally cannot cover it.
Also corrects the standing-mounts Agent Note, which still listed `tasks-local`
among the stateful PRESET plugins.

The model reads a PNG/JPEG/WebP/GIF file, the bytes commit through the
durable attachment lifecycle, and the tool result carries the real
ImageBlock so the image enters context from the next request onward.
FileSystem gains a bounded readBytes primitive (local + E2B providers);
registration is conditional on the attachment store, and a strict
execution gate refuses routes that do not declare image input, so a
text route's durable history stays free of image blocks. llm-replay
models may declare inputModalities, letting keyless ACP snapshots pin
both the sha256-referenced success and the verbatim refusal.
Supersedes the withdrawn route-scoped design of PR #598; the decision
record is .agents/notes/implemented/feature/2026-08-10-minimal-read-image-tool.md.
The skills capability moves back to the host plane as one singleton, layered
with the ScopedLayers infrastructure the tools registry established: a
registration files into its calling context's layer (repository plugins and
host rows land global, a preset's skill-local lands in that preset's layer),
and a read merges the global layer with the viewing scope's chain, the
nearest layer winning duplicate names outright while rank keeps deciding
duplicates within one layer.
The web-app bundle re-enables the base skill registry row (skill-local and
tool-skill stay preset-owned), the standard preset drops its isolate skills
realm for bare rows over the host registry, tool-skill passes the calling
agent as the view scope, and the gateway's skills domain reads the host
registry in the presenter scope — a cold session now resolves its recorded
preset's standing key instead of failing.
The merge-forward took the parent's module-graph verbatim; the merged
tree adds the sandbox-windows-acl package and dsh-session edges.
verify-module-graph is a ci-static gate, not in local doc-sync.
Move the triplet to implemented/architecture/, rewrite Proposal into a
present-tense Decision, fold Acceptance criteria and Risks into
Consequences (recording what pins the result), retitle the migration
section to what the move actually touched, and repoint the seven
inbound FIXME/README links.
The new package and its dependency edges changed the generated graph;
`verify-module-graph` runs in the CI static gate rather than doc-sync,
so the stale file only surfaced after the push.
- restore the parent's AGENTS.md body around this branch's e2b row (the
replay had resurrected the pre-profile-CLI layout, deleting the api/,
bundle/, settings/, and credentials/ groups); the fs/lsp row
condensations stay for the word budget
- aggregate the composite rollback failure, not the original error, when
private state cleanup also fails — a surviving remote group is no
longer hidden by a later cleanup error (triple-failure regression)
- own the state directory before the makeDir RPC, matching the terminal
transaction, so a cancellation racing a committed creation still
enters cleanup
- drop the hidden pollMs parameter defaults; the schemastery default is
the one home, and tests pass the cadence explicitly
- restore spawn/spawnTerminal graceMs validation to the seam's
documented bound (the earlier removal cited subprocess-local as not
validating; it does), with rejection regressions
Master turned THIRD_PARTY_NOTICES.md into generator output (the branch's
hand-added e2b row carried a stale dotenv entry), and the cascade's
ours-side resolution flattened the module graph to the parent's content;
both regenerate from the current tree.
Restores master's vitest config and packages-README pairing record (the
replay had carried old-lineage copies; this branch claims neither), and
regenerates the doc graphs, catalogs, and architecture pairing the
replay's ours-side resolutions had flattened to master's content.
