{"content":"Development journal for commit fb12d5e4 (fix: derive payload dir expectations from recorded call args in the private-chat hygiene test).\n\nMakes the send_private_chat fs-hygiene test concurrency-immune. The independent 5-way merge regression flagged that the test scanned global os.tmpdir() for payload dirs — under the repo's parallel `node --test` runs, concurrent payload users (e.g. the upload_file tests) could make it flake. The expected dir names are now derived from the test's own recorded CLI call args (dirname of each --request-file path), deterministic regardless of neighbors. Product code unchanged.\n\nThis closes the last open finding across the six capability-parity PRs (#49–#54): five-way merge simulation green (45/45 new tests after union-resolving 4 trivial index.ts hunks), zero neighbor delta vs plain main, zero dead tool references, and the one flake candidate now pinned to its own runs.\n\nVerification:\ncd dsh-plugin && pnpm run build && node --test tests/private-chat-tools.test.mjs\n→ exit 0, 9 pass, 0 fail\n\nFiles:\ndsh-plugin/tests/private-chat-tools.test.mjs","contentType":"text/plain;utf-8","attachments":[],"quotePin":""}
