Summary

• Overlap fallback was uncorrelated. Without a worker overlap source, load_context computed each agent's overlap with ARRAY(SELECT unnest(item_keys) FROM agent_distinctive_items INTERSECT …). The compound select carries its own FROM, so every agent got the whole index's overlap with the candidate. Every record written before the worker overlap path shipped is therefore wrong: genuine copies were excluded as "released" (released_base = every item), and other scores were inflated. The fallback now runs the same numpy membership pass in process over the streamed eligible rows.
• Owner-name hint. The same-owner namespace hint now uses every agent name on the owner's hotkeys and attested links, including later uploads. Before this, an operator's first agents flagged at about 1,348 against their own alt-key agent, because its namespace is named after the operator's later line.
• Warm worker. An idle tick syncs the worker index and caches up to 8 more released fingerprints. The first evaluation or operator live read after a restart no longer loads everything at once; a cold live read was taking more than 20 s.
• Re-evaluation. SIGNAL_VERSION moves to uc3, so every candidate is re-evaluated in the background on the corrected paths, newest first.

Test plan

• test_unreleased_copy.py: the fallback overlap equals the true intersection, an unrelated agent has no overlap, and owner names include a later same-hotkey agent
• unreleased, copy-court and upload Platform tests

🟡 Medium · bug — Same-coldkey agents are omitted from owner namespace names · 🔎 Verified by trace

rows contains only the candidate and agents that overlap it, so this hotkey set omits an agent under another hotkey that shares the candidate's payment coldkey but no distinctive items. If that agent's name identifies the shared namespace, owner_names misses the same-owner hint and the candidate can be incorrectly flagged as a copier; include agents associated with the candidate's coldkey when gathering names.

Why Ditto flagged this (confidence 86%)

At lines 330–333, _owner_names derives names only from hotkeys in rows and links. Since rows is built from the candidate and agents with shared distinctive items (lines 260–268), a same-coldkey agent with no overlap is excluded even though payment coldkeys are part of the ownership model (lines 270 and 279–280); its name therefore cannot contribute to the same-owner namespace hint.

In `apps/platform/ditto/db/queries/unreleased_copy.py`, update `_owner_names` (lines 316–335) and its call at line 312 so it can use the candidate's payment coldkey. Include hotkeys for agents that paid with that coldkey when collecting owner names, in addition to the existing overlapping-row and linked-hotkey sources. Add a regression test where a same-coldkey agent shares no distinctive items with the candidate but its name identifies the shared namespace; verify the same-owner hint prevents a false copier flag. Run the focused unreleased-copy tests.

Recognize owners by all agent names in namespace hints — This change advances the unreleased-copy signal to uc3 and expands the owner-name hint to include names associated with the owner’s hotkeys over time, including names from later uploads. The database query gathers those names for the candidate owner and linked hotkeys, and a regression test covers an owner renaming a later agent. Review the hotkey/link scope and how including future names affects the shared-namespace hint.
