There was a problem hiding this comment.
For a legacy Claude subagent whose attributionAgent is absent or appears late in a large transcript, discovery invokes _claude_subagent_attribution, which iterates the entire file before JSONLTailer.read_new_lines(..., max_read_bytes=1_048_576) is ever reached. This bypasses the new 1 MiB backfill read cap (and can repeatedly require a multi-GB discovery read), allowing a single historical transcript to stall or exhaust the backfill's I/O/memory budget; make attribution detection bounded or defer it to the capped tailing path.
Useful? React with 👍 / 👎.

- Around line 5-6: Update backfill_run_lock to resolve the registry path before
deriving its lock key, ensuring symlink and alias paths share one lock. Remove
direct fcntl usage and reuse the project’s shared cross-platform POSIX/Windows
run-lock helper instead.
In `@src/brainlayer/watcher.py`:
- Around line 656-666: Prevent the watcher’s read loop from reading again when
an unterminated buffer has exhausted its cap: update the read logic around the
buffer handling in src/brainlayer/watcher.py lines 656-666 to skip the file read
when remaining_budget is zero or negative, while preserving reads when budget
remains. In tests/test_jsonl_watcher.py lines 542-551, use a single newline-free
record larger than the cap and assert repeated polling does not increase the
buffer.
In `@tests/test_jsonl_watcher.py`:
- Around line 542-551: Update test_read_new_lines_bounds_offset_zero_read_bytes
to use an unterminated JSONL record larger than 256 bytes instead of repeated
newline-terminated records. Call JSONLTailer.read_new_lines repeatedly with
max_lines=1 and max_read_bytes=256, asserting after each call that
tailer._buffer never exceeds 256 bytes.

Use a canonical, cross-platform run lock in src/brainlayer/backfill.py:53-68. backfill_run_lock still imports fcntl directly, so this path is broken on Windows. It also keys the lock off the raw registry path, so symlink/alias paths can take separate locks and run concurrently. Resolve the registry path before deriving the lock and reuse the shared POSIX/Windows lock helper.

Enforce the read cap for oversized unterminated records. A full buffer currently triggers another full-budget read on each poll.

Exercise an oversized unterminated record.
Short complete lines drain the buffer and cannot catch the cap regression. Write more than 256 bytes without a newline, call read_new_lines repeatedly, and assert the buffer never exceeds 256 bytes.

For a time-windowed run, accepting an explicit --registry lets callers select the live offsets.json (the option help still says that is its default). WindowedFlush confirms offsets for every scanned out-of-window record, so if a live watcher has not yet read a file, its next tailer/restart begins at the backfill's EOF watermark and permanently skips those records without indexing them. This remains possible on the non-legacy window path despite the legacy discovery fix; reject the live registry for windowed backfills or namespace the supplied path before constructing the watcher.

Summary
Stack
Stacked on #596 because the production replay depends on its corrected reverse-ingest denylist. Review and merge #596 first; do not merge this PR independently.
Verification
Operations
Production receipt and before/after chunk counts are tracked in the lane collaboration document. The raw transcript JSONLs are retained.
No merge requested; ready for owner review.
Note
Medium Risk
Touches ingest paths, offset persistence, and denylist semantics for production backfills; behavior is heavily tested but mis-filtered windows or watermark logic could skip or duplicate data.
Overview
Adds bounded, idempotent transcript replay to
