WARNING: replay_size=0 makes subscriber queues unusable
asyncio.Queue(maxsize=0) causes put_nowait to always raise QueueFull. The old code used an unbounded asyncio.Queue() which worked regardless of replay_size. Consider max(1, self._replay_size) or a conditional to preserve unbounded behavior when replay_size <= 0.

🚀 Performance & Scalability | 🟠 Major | 🏗️ Heavy lift
Evict replay state when a project is deleted.
delete_project() only marks the project as deleted. It does not remove ProjectEventBroker._replay[project_id]. publish() creates one deque per project, and unsubscribe() removes only _queues. A per-deque maxlen does not bound the number of project keys. Remove deleted projects from _replay, and use a TTL or global key cap for projects that are not deleted.

Reject or normalize a zero replay size.
If a caller constructs ProjectEventBroker(replay_size=0), asyncio.Queue(maxsize=0) is unbounded. An inactive subscriber can then retain every published event. Validate replay_size >= 1, even though the application currently uses the default value of 32.

Lead review of the fix-forward — the
The helper is explicit about it — Worth noting why nobody saw this on #2964: shard 1 failed on the NameError and fail-fast cancelled shards 3 and 4, so the ownership tests never reported. The working half masked the broken half. Existence-hiding 404 is a defensible posture — I'm not saying it's wrong. I'm saying it's a security-contract decision for the whole project API, and it doesn't belong inside a fix-forward of a nits PR, applied to six endpoints, contradicting the existing tests, with no note in the body. Please make If you think existence-hiding is the right call, say so in a comment here and I'll card it as its own change: it needs to sweep every project route, update Everything else in this fix-forward looks right — I'll re-review the broker lock and |

[REVIEW — taOS-dev lead] NOT MERGING. CI is red on a real regression, and it is a class, not the three tests that caught it. Reviewed head What is right
Blocking 1 — six write routes silently changed 403 → 404 (undeclared, not in the card, not in the commit message)

Correction to my review above — Blocking 1 was mis-framed. Do NOT revert the six handlers. I called the 403 → 404 swap "undeclared, not in the card". I then read
So routing all six through What actually blocks the merge is unchanged in substance: CI is red.
The card changed the contract; the contract tests have to move with it in the same PR. To re-push:
