JSON Lines (JSONL) collector for the sampling profiler.
Emits a normalized newline-delimited JSON record stream suitable for
programmatic consumption by external tools, scripts, and agents. Each line
is one JSON object; consumers can parse the file incrementally line by
line, but the producer writes the whole file at the end of the run (it is
not a live/streaming producer).
Record schema
=============
Every record is a JSON object with at least ``"type"``, ``"v"`` (record
schema version), and ``"run_id"`` (UUID4 hex tagging the run; allows
demultiplexing concatenated streams). Records appear in this fixed order:
1. ``meta`` (exactly one, first line)::
{"type":"meta","v":0,"run_id":"<hex>",
"sample_interval_usec":<int>,"mode":"wall|cpu|gil|all|exception"}
``mode`` is omitted when not provided.
2. ``string_table`` (zero or more)::
{"type":"string_table","v":0,"run_id":"<hex>",
"strings":[{"str_id":<int>,"value":"<str>"}, ...]}
Strings (filenames, function names) are interned to keep repeated values
compact. IDs are zero-based. Each chunk holds up to ``_CHUNK_SIZE``
entries, and each entry carries its explicit ``str_id`` so consumers do
not need to infer offsets across chunks.
3. ``frame_table`` (zero or more)::
{"type":"frame_table","v":0,"run_id":"<hex>",
"frames":[{"frame_id":<int>,"path_str_id":<int>,"func_str_id":<int>,
"line":<int>,"end_line":<int>,"col":<int>,
"end_col":<int>}, ...]}
``end_line``/``col``/``end_col`` are *omitted* when source location data
is unavailable (a missing key means "not available", not zero or null).
``line`` is ``0`` for synthetic frames (for example, internal marker
frames whose source location is None). Frame IDs are zero-based.
4. ``agg`` (zero or more)::
{"type":"agg","v":0,"run_id":"<hex>","kind":"frame","scope":"final",
"samples_total":<int>,
"entries":[{"frame_id":<int>,"self":<int>,"cumulative":<int>}, ...]}
``self`` counts samples where the frame was the leaf (currently
executing); ``cumulative`` counts samples where the frame appeared
anywhere in the stack (deduped per sample so recursion does not
double-count). ``samples_total`` is the run-wide total, repeated on
each chunk so a streaming consumer always knows the denominator.
5. ``end`` (exactly one, last line)::
{"type":"end","v":0,"run_id":"<hex>","samples_total":<int>}
Presence of ``end`` is the consumer's signal that the file is complete.
Forward compatibility
=====================
Consumers MUST ignore unknown record ``"type"`` values and unknown object
fields. New fields will be added by adding optional keys; an incompatible
schema change will bump the per-record ``"v"``.
