The no-unknown-casts ratchet landed on master after this branch, so the new stub tables in the ACL failure paths can no longer assert through unknown. Route them through a typed partial stub, type the bigint handles as NativePtr, and prune the three retired baseline entries.
Re-record the session-snapshot README bilingual pairing sidecar, and admit
the source-reference regression fixture with the v4 producer-owned `user`
message source kind.
The attachment-policy fixtures introduced three assertions to unknown and
changed two previously recorded assertions. The new repository gate rejects
those escape hatches even though the earlier branch CI passed.
Give the user, tool-result, and inbox fixtures their required V4 message
metadata and declared identifier types. Declare the fixture's plugin content
tag through ContentBlockMap, and check the flat tool-result fixture directly
as its concrete SessionEvent type. Keep intentional malformed inbox entries
and opaque extension fields in the existing negative cases.
Remove all five unknown bridges without adding allowances. Delete the two
baseline entries retired by the rewritten existing fixtures; the other
three assertions were never part of the accepted baseline. Attachment
runtime code and the tests' access-denial and complete-log assertions remain
unchanged.
Validation: the Host TypeScript aggregate and all 52 archive tests pass.
verify-no-unknown-casts reports no new or stale entries, with 1575 existing
assertions remaining; the baseline adds zero allowances and retires two.
The merged concurrent migration test used an as-unknown widening assertion after JSON.parse. Master now rejects newly introduced unknown casts, so that test blocks the repository gate and unrelated PR validation. Give the map callback an explicit unknown return type instead. Keep the gate baseline unchanged; parsing and assertions have the same runtime behavior.
An unexpected visitor rejection represents a batch-level programming or reporting failure, rather than a normal per-Session refusal. The scheduler already drains its active workers before surfacing it and does not start deferred retries. State that behavior explicitly so callers do not assume the retry pass runs after a fatal batch failure.
The parent-child integration case can succeed without observing a race, while scheduler-only tests do not exercise the actual error classification or CLI output. Inject one genuine source-change error at the persistence open boundary in an isolated child process, then delegate to the real backend. Assert DEFERRED, completion of the other input, one RETRY, preserved source bytes and the resulting parent catalog. This adds no production test hook or timing-based race.
The command promises any positive safe integer, but its additional decimal-spelling regex rejected valid expert overrides such as 1e2 and +1. Let Number parse the supplied value and retain the positive safe-integer check. This preserves the CPU-based default cap while allowing equivalent numeric spellings and larger explicit values.
The source-entry regression creates a Windows junction to the real checkout. Its local unlink normally removes it, but fallback teardown must remain safe if that unlink fails. Use the repository fixture cleanup helper to unlink reparse points before recursive deletion and retain its bounded Windows handle-release retries. This changes only test resource cleanup.
A text error list does not show how failures are distributed across historical source versions or let developers aggregate repeated rejection reasons. Emit and save the same JSON report with per-version outcomes, stable failure groups and per-input diagnostics, plus runtime, checkout and report locations. Keep source versions from physical discovery rather than migrated handle headers.
Classify only known diagnostic fields such as unexpected members, unknown events, child prerequisites and sequence gaps. Preserve original messages and use an explicit fallback for other failures; the report makes no inference about historical producer bugs and cannot influence admission or retry decisions. Regression checks cover printed/file/log equality, private report files, grouped distinct sequence coordinates and source-file preservation.
Sequential corpus migration waits for each Session to finish I/O and publication verification before starting the next. Use a bounded queue with one shared persistence Context, defaulting to available CPU count capped at 16. Expert --jobs overrides accept any positive safe integer. Stable input indices and separate completion counts keep interleaved progress useful for large corpora without opening every log simultaneously.
A concurrently upgraded child can invalidate its parent evidence. Preserve the backend revision checks and defer only the explicit source-change error for one serial retry after initial work drains. Corruption, unsupported formats and writer locks remain failures; historical files and existing V4 data remain unchanged. Deterministic scheduler tests cover 10,000 inputs, bounded overlap and retry ordering, while real raw/zstd corpora verify parent catalogs and serial-equivalent output. Performance timing was stopped at user request because the host has competing workloads.
Give developers one pnpm command to exercise the release migration against their own Session roots. Inventory physical generations so malformed entries remain visible, then reuse JSONL write-open locking, validation, and exclusive successor publication with the full root available for child-catalog evidence. Open existing V4 files read-only and preserve every historical generation.
Report each selected source and outcome, continue after individual failures, repeat all errors at the end, and retain a private temporary report with checkout/runtime details and full causes. A failed run exits nonzero. Explicitly close handles because source-launch await-using lowering inside a loop can retain a previous iteration error. Real-entry regressions cover raw/zstd tool-result conversion, repeated runs, unchanged originals, failure continuation, and unsupported layouts. Document the command in the migration cookbook.
Integrate the master tip observed for the final V4 landing preparation on
top of the already merged migration stack. Preserve the V4 writer, flat
message migration, extension policy, catalog validation and historical
recordings while bringing in upstream profile resolution and desktop/UI
changes.
Resolve four generated translation-pairing records from the combined
English/Chinese text. Keep this master checkpoint separate from any
integration fixes and retain all reviewed parent history. Follow-up
validation covers the affected launch/UI paths and migration replay.
Convert an unknown legacy plugin wrapper such as
{kind: 'plugin', plugin: 'acme'} into {kind: 'plugin:acme'}, retaining the
complete plugin name after one prefix. Keep the existing explicit
first-party producer renames and preserve all non-identity metadata.
A direct source already records its producer in kind. Reclassifying
unknown direct kinds into plugin:source:<name> needlessly changes that
attribution and forces plugin consumers to adopt new identifiers even
though V4 accepts their existing representation. Return every valid
direct source unchanged, including already-prefixed names. Remove the
obsolete direct-kind table and two-category identity helper rather than
adding collision classification or another mapping layer.
Update the source conversion examples, codec/restore regressions, and
native fixture producers together. Refresh only the owning Python
advanced scenario's unshipped V4 outputs; preserve historical V0-V3
recordings and their generation selection. Event names, content tags,
and ToolSchema migration remain separate concerns.

The Consumer-owned strictness bullet names the Loader subtree that agent presets own instead of the runtime resolution; the service field, its file comment, the dispose JSDoc, and the route JSDoc use interception; the native-after-interception route documents both anchors it can carry; stale module-fallback comments name the runtime resolution; importFromResolution matches its parameter.
