The previous commit added the bulk read/write library surface in every
client; this commit makes that surface reachable from each client's CLI
and exercises it through scripts/run-client-e2e-tests.ps1.
Five new subcommands in every client CLI (.NET / Go / Rust / Python /
Java): read-bulk, write-bulk, write2-bulk, write-secured-bulk, and
write-secured2-bulk. Each follows the existing subscribe-bulk shape:
- read-bulk takes --server-handle, --items <csv tag list>, and
--timeout-ms (0 = worker default). JSON output carries the
BulkReadResult fields, including was_cached so the e2e matrix can
verify the cached-path semantics.
- The four bulk-write families take --server-handle, --item-handles
<csv>, --type, --values <csv>. write2-bulk and write-secured2-bulk
add a single --timestamp applied to every entry; the secured
variants take --current-user-id and --verifier-user-id. All four
output BulkWriteResult JSON.
A new -SkipReadWriteBulk switch on the matrix script (default OFF)
controls two new e2e phases:
- After the existing subscribe-bulk phase leaves tags advised, the
script runs read-bulk against the same tag list and asserts most
results return was_cached = true. This is the only e2e coverage of
the cache-then-snapshot fork — the unit + gateway tests verify the
semantics with a fake worker, but only the live cross-language
matrix proves the cache populates from real OnDataChange events and
survives the round-trip through every client''s JSON parser.
- When -VerifyWrite is set, the write phase now also runs a single-
entry write-bulk against the same writable item handle (using a
distinct sentinel value) and asserts a per-entry success. Confirms
the BulkWriteResult wire format end-to-end without complicating
the OnWriteComplete echo assertion the single-item phase already
verifies.
Dry-run validation passes for all five clients: each emits the correct
read-bulk and write-bulk CLI invocations with the right flags.

Client.Go-002: the Events/EventsAfter compatibility path silently dropped
events when the 16-slot results channel filled — it cancelled the stream and
closed the channel with no error delivered. sendEventResult now evicts an
old buffered event and delivers a terminal EventResult carrying the new
exported ErrEventBufferOverflow before close, so the overflow is observable.
Client.Go-003: parseInt32List panicked on a malformed -item-handles token,
crashing the CLI with a stack trace. It now returns an error that
runUnsubscribeBulk propagates, exiting 2 with a clean message.
