capability.list gains an optional AbortSignal threaded from the RPC
carrier's request signal (the pickDirectory pattern): a disconnected or
timed-out caller stops the opendir loop instead of the scan outliving
its caller, and the abort surfaces as its own reason rather than a
directory-unreadable dressing. boundedInsert rejects a full window's
at-or-beyond-tail candidate on one comparison and binary-inserts
retained candidates, so an oversized level no longer pays a window scan
per dirent.
One list call now materializes at most maxEntries child rows (config,
default 1000 - GitHub's web-UI directory-listing bound). Candidates sort
before probing so a cut level keeps the name-sorted head and symlink
probing stops with the bound, and DirectoryListing carries a required
truncated flag on the seam and the wire so clients can state
incompleteness instead of silently missing tail entries.
Union resolutions throughout — the fixture serves both the goal and plan
projection units (catalog gains /goal beside /plan; the retired
goal-fixture sample command yields to the real goal mirror), the mux
baseline spec expects all four unit frames, and the tsconfig paths /
Model Experience allowlist carry both domains' outlets.
The TUI keyless smoke exposed the wrong idle signal: /plan submitted while
the driver is between turns still saw status running (checkpointing), so
the selection queued and the immediate copy never appeared. The commit
gate is now the log's own open-turn fold — plan/mode commits at once
whenever no turn is open, and queues only inside one. Specs drive the
distinction through explicit turn/start / turn/end events instead of a
fake status; the keyless smoke pins the new idle copy on both /plan and
/plan off; regenerated cordis/service catalogs ride along.
Inherited sandbox and approval events were part of the constructor seed. Session.firstLiveSeq classifies every constructor event as replayed history, so telemetry adoption skipped these child-only creation facts even though no parent or prior process had exported them.
Capture the parent overrides at the same synchronous delegation boundary, but append the events during the child factory setup while the session is still unpublished. They remain ordered after fork history, persist with the first child batch, and retain last-event-wins behavior while landing on the live side of the telemetry boundary. This uses the existing setup and session append contracts instead of adding another seed category or telemetry special case.
Add regression coverage for exporting an unpublished suffix without re-exporting constructor history, assert the spawn and fork firstLiveSeq boundaries, and restore the public seed documentation to replay/fork history only.
- Regenerate the cordis/config catalogs, doc graphs, and module graph for
the four newly mounted plugins and the goal projection key.
- ui-goal README pair (Model Experience indirect + Known Limitations) with
its i18n record; sentence-allowlist entry for the indirect form.
- knip workspace entry for ui-goal (tsx test pattern).
- type-equiv manifest follows the seven host-coupled goal symbols to
domain.ts.
- The web-slash-command-dispatch note documents the dropped prompt
interception and leaves with it; the goal-bar note's code paths follow the
component into ui-goal (pairing re-recorded).
The persisted row (sessionId, key, stateVersion, observedSeq, state)
becomes (sessionId, key, ver, seq, val) — the cache medium repeats these
three names for every unit of every session, so the long forms dominated
the JSON payload. ProjectionCheckpointRow and the checkpointRow zod spec
rename together; the domain spec bumps to v3 (cache semantics: the old
medium is discarded, not migrated). The unit-facing declaration keeps
stateVersion — only the persisted/checkpoint row shape changes.
gen-cordis-catalog/api, config and persistence catalogs, and doc graphs
regenerated over the new sessionProjectionCache service and the registry's
checkpoint faces. Classifications: ProjectionCheckpoint joins the type-link
exemptions (owned by the projection package source), Partial joins the
foundation names, the cache service gets its capability-seam role row, and
the package takes the one-sentence Model Experience contract (host-side
read-model accelerator, no model surface).
Regenerate the cordis/config/persistence catalogs and the module graph for
the ui-plan package and the plan projection unit; add the ui-plan Chinese
README and the Model Experience indirect sentence (allowlisted: the control
dispatches /plan lines, dsh-plan-mode owns the model surface); carry the
QuestionComposer Markdown/scroll improvements into the Chinese ui-question
README; re-record the three touched translation pairs.
The parent implementation introduced sandboxMode and approvalPolicy as generic SessionHeader fields, then propagated those fields through both persistence backends, session-query indexes, collision checks, policy-specific seed-boundary folds, catalogs, and a broad test matrix. That storage plane is unnecessary: Session already accepts a validated constructor seed, and persistence captures that seed when the session is announced before committing its first batch.
Capture each parent override synchronously at delegation, append source-tagged sandbox/mode and approval/policy records after the optional fork prefix, and create the child with that combined seed. Keeping header.seedLength at the original fork-prefix length preserves lineage while ordinary last-event-wins folds make the inherited records outrank stale parent history and remain subordinate to later child switches. Unswitched parents still stamp nothing, so children continue to follow deployment defaults.
Remove the generic header fields and every persistence/query/schema branch built around them. Collapse the inheritance suite from ten leaking scenarios to four owned-context cases covering real filesystem confinement, stale fork precedence, delegation-time capture, and the no-override path. The assembled headless snapshot now asserts the persisted inheritance event directly.
This keeps the security behavior while restoring policy ownership to the existing event log and deleting the speculative durability machinery that the original tests did not exercise.
Retarget the feature branch to the current master tip without rewriting its existing review history. Keeping this as a dedicated merge checkpoint makes the later simplification diff attributable to the stacked child rather than mixing base movement with design changes.
Resolve the identified-message API drift in the feature tests by constructing complete user messages, reading the nested tool-result message shape, and adapting the prompt-submit listener signature. Preserve both sides of the user-approval conflict: master’s createUserMessage wrapper and the feature’s inherited-policy attribution.
Regenerate the Cordis and persistence catalogs, re-record the session README pair, and refresh the affected ACP/headless fixtures so derived artifacts describe the merged source rather than either parent in isolation.
Validated with the focused policy/session/persistence/query suites (430 tests), focused ACP/headless snapshots (3 tests), build, doc-sync (25 gates), lint, hygiene, and git diff checks.
ds-review-bot round 4. On Windows, isAbsolute admits rooted drive-less
forms (\foo, /foo) that resolve() then rebases onto the process's current
drive; both browse primitives now gate on a fullyQualified check (drive
letter or UNC on win32, POSIX-absolute elsewhere) with a platform test
seam, per-platform unit cases, and the contract wording updated on the
seam, the backend README pair, and the error messages.
The picker-kind effect also kept a resolved 'dialog' across close, so a
backend swapped while the menu was closed could paint the stale entry for
one frame on reopen; the close arm now clears the state, pinned by a
reopen-under-pending-read race test.
ds-review-bot round 3. The seam package broke the service-package export
contract (named export only), so the config catalog filed it under Other
libraries and default imports failed; it now default-exports DirectoryPicker
like every abstract seam, and the regenerated catalog lists it as one.
The picker-kind effect also let a settlement from a superseded flow open
leak into the current one (close/reopen mid-describe, or a reconnect that
swaps the backend): the read now resets the affordance on every open and a
cleanup-toggled flag discards obsolete settlements, both directions pinned
by jsdom races.
ds-review-bot round 1: the seam documented a merge-extensible union but
shipped a closed alias, and the gateway schema rejected any kind beyond
dialog/browse — a third backend could neither implement the seam nor be
advertised. The union now derives from an augmentable DirectoryPickerCapabilities
map, host.describe.directoryPicker preserves unknown wire kinds, and the
browse fixture applies listDirectory's root special case so creating under
'/' no longer mints a '//name' identity.
The web GUI's folder picking was hardwired to one interaction: a native
OS chooser compiled into the gateway, unusable for remote deployments
and swappable only by editing apiproxy source.
Directory picking becomes a three-package capability seam in
packages/host: ctx.directoryPicker returns a discriminated capability —
dialog (the extracted native chooser; host-display only) or browse
(new: one-level listing + child creation over Node stdlib, hidden flags
host-stamped, symlinks followed, ancestry crumbs; remote-capable). The
gateway injects the seam, advertises the kind via
host.describe.directoryPicker, serves host.listDirectory /
host.createDirectory under browse, and answers
directory-picker-unavailable across kinds. cordis.yml is the swap
point; apps/cli keeps dialog mounted, so behavior is unchanged until
the in-app browser PR flips the default. The connection fixture serves
a deterministic browse tree; WorkspacesService gains the browse calls
the browser UI will drive. Decision record:
