0.1.9 - 2026-07-04

Fixed

• Vector-store metadata filters now bind JSON path segments as query
  parameters, preventing metadata filter keys from being interpolated into raw
  Postgres SQL while preserving nested metadata lookup support.
• Local sandbox file operations now resolve symlinks before containment checks,
  blocking reads, writes, listings, globs, and recursive grep matches that
  would escape the sandbox root through symlinked paths.
• Shell policy string allow rules now require a command boundary and reject
  unquoted shell chaining or command substitution, so an allowed prefix cannot
  authorize allowed_cmd; malicious_cmd.
• Local sandbox command execution now streams stdout/stderr into a bounded
  buffer controlled by max_output_bytes and marks oversized output as
  truncated instead of accumulating unbounded command output in memory.
• Recursive text splitting now rejoins chunks with the separator that actually
  split each level, preserving source whitespace and valid add_start_index
  metadata for word-level splits.
• OpenAI chat message conversion now deduplicates assistant tool calls by
  request id when the same call is present in both tool_calls and content
  blocks, avoiding duplicate ids in provider requests.
• Manual graph state updates now compute next tasks through the normal
  scheduler, so conditional and guarded edges route correctly after
  update_state/4.
• Subagent stream handles now route child values, updates, and errors only to
  the most specific active subagent handle, preventing nested child events from
  leaking onto ancestor handles.
• Anthropic usage parsing now reports ephemeral 5m/1h prompt-cache writes under
  canonical cache-creation usage, so cost and telemetry accounting no longer
  treat those cache writes as zero.
• Memory full-text queries now search canonical value and metadata text instead
  of Elixir inspect/1 output, avoiding matches on wrapper field names and
  struct implementation details.
• Stream mux heartbeats now respect finite stream timeouts, so a hung producer
  cannot keep a live stream open forever by emitting heartbeat events.
• PII middleware now redacts assistant tool-call arguments and buffers streamed
  text across chunk boundaries, preventing split PII from bypassing streaming
  redaction.
• Fixed low-severity edge cases in provider and tool adapters: OpenAI nil
  tool-call arguments now encode as {}, OpenAI usage totals are inferred when
  omitted, Z.ai streams keep id-less delta chunks, Moonshot rejects unsupported
  audio/file blocks, file search preserves snippet case and counts filename
  matches, tool defaults apply before validation, stream lifecycle routing
  tolerates payload-only message ids, and ETS cache pruning is serialized.
• Partial JSON parsing now repairs truncated JSON in a single capped structural
  pass, avoiding superlinear prefix scans on streamed tool-call arguments.
• Stream/message transforms, Google SSE merging, text-splitter start-index
  tracking, and Z.ai response conversion avoid repeated list appends or
  full-document rescans on streaming hot paths.
• WeaveScope trace export now disables Req's internal retry loop and logs
  failed uploads with BeamWeaver exporter context, so timeout diagnostics point
  at the trace export path instead of only Req.Steps.
