setScopeParent could re-link any key from anywhere, leaving the
blank-session-only recompose rule entirely to caller discipline. The
relation now binds once — a second bind throws — and re-linking exists
only on the ScopeParentBinding returned to the original binder, the
private-capability shape the package conventions prescribe for a
single-caller operation. The preset roster keeps each composed agent's
binding in a WeakMap keyed by the agent, making it the sole authority
that can move an agent between standing compositions; the blank-session
contract itself stays with the gateway, which alone can see what a
session logged.
Steering bubbles render as plain user bubbles; a mid-turn steer is
recognizable by its position in the flow. The runtime SteeringMessageNode
projection and pending-steering lifecycle are unchanged.
Partially supersedes the 2026-08-04 context-source and steer marks note;
the new simplification note owns the removal rationale.
The durable sandbox/acl-session event carried a workspace binding that
always equals the session cwd and a random temp path that only needed
to be stable per session. Both are now derived: the temp subdirectory
is sha256(session id + workspace), created exclusively and removed on
provider dispose, so fork/resume semantics fall out of the derivation
and the record, its fold/provision/tamper validation, the immediate
flush kick, and the session-store dependency all disappear.
The persistence catalog recognizes SessionEventMap augmentations of
'@deepseek-ai/dsh-session/types' alone, so the selected event's old
root-specifier declaration compiled but silently vanished from the
generated catalog. The hermetic scaffold e2e still addressed the skill
registry as a preset-realm service; under the layered host registry the
composed agent's view is a scope read, and the ambient-root isolation it
proves is unchanged.
The persistence catalog recognizes augmentations of
'@deepseek-ai/dsh-session/types' alone, so the old root-specifier
declaration compiled but silently vanished from the generated catalog; the
Agent Note also drops its internal repository link for the public-links
gate, and the persistence catalog pair re-records with the restored
agent-preset section.
The shipped headless profile is base + headless (the direct-core front
door), and its installation-owned migration rewrites the old three-bundle
tuple down to that template, so a one-shot run composes no preset roster.
The runner's optional preset composition was compensating in the wrong
direction: it re-added roster reads the shipped profile never satisfies,
and its golden pinned a header field only a roster-bearing deployment
produces. The runner, the headless bundle manifest, and the dsh-run golden
return to the direct shape; skills in a direct run flow through the base
host rows' global layer, which is what the repository-plugin e2e proves.
The battery self-exclusion widens from references/ to the whole skill
directory (SKILL.md quotes the same leaked shapes), and the invocation
rules name the owning note's evidence self-hits; natural-language
battery lines gain -i so sentence-initial capitals hit; the actually/
wait false-positive family states that no committed line probes it.
The one test now says resolvability clears only this skill's bar —
current-state surfaces still reject resolvable change stories; the
never-deletion-alone rule is scoped to passages that carry factual
clauses. The first few-shot Fixed example links the real web
input-machine note path. The citations note's Verification exemption
(+zh, pair re-recorded) names the skill's files and the note's own
quoted evidence, making the claim mechanically honest.
The suite composes over the ambient DSH home, so a fixed session id
collides with the log a previous run persisted once the tool-execution
path checks persisted identity.
The skills subsystem page and dsh-skill README describe the host+per-scope
layers, SkillViewOptions joins the type-equiv corpus and the cordis-catalog
type pages, generated catalogs pick up the shifted source refs, and the
architecture Agent Note records the decision, the nearest-layer-wins
precedence choice, and the rejected alternatives.
SKILL.md carries the resolvability test, the 8-class taxonomy, the
sanctioned-keeps list, and the owner-first fix workflow; references/
carry 24 few-shot calibration blocks (both citation-boundary directions
plus the four overcorrection traps caught in the purge's review rounds)
and the EN+zh recall batteries with their false-positive families.
dsh-doc-standards' inline leakage probes collapse into a link to the
new skill; dsh-prose-standard gains the sibling pointer; the
committed-artifact-citations note (+zh, pair re-recorded) records the
skill as the operational workflow and exempts its calibration examples
from the battery expectation.
The shipped-Web e2e enables the bundled badge skill as a stand-in for a
repository plugin's deployment-level provider and asserts the layering both
ways: a standard-preset agent's view merges the global layer with its
preset's local discovery and its loader tool resolves the global skill,
while the host view stays global-only and a core-web agent can read the
layer but composes no loader tool.
This reverts commit f12c131ee9fdbc01b9294c8dc2c73cd36ab717cf.
The layered host skill registry closes the gap the bypass recorded: a
repository plugin's skill root registers into the global layer and reaches
every preset-composed session's catalog, so the fixture declares its skill
root again and the e2e proves the full skill, MCP, and TypeScript
contribution set. The accidental .claude/launch.json from that commit goes
with it.
