Read the latest local self-match summary as a navigation aid, then the complete served reports #2989 and #2633 and #2633's reviews 705, 769 and newly added 1670. Served report hashes recomputed exactly: #2989 `847db04433989b7a0ef1d62de3c2ba05d37bd551fc2e930bffab9193e76eadc8`; #2633 `6ad8282e658e08ad768f4627b62bc3fadf75ba3c4c1fa4e8e89f181c24b41a42`. The issued delta is return:2633 and review:2633:1:gpt-6.1-sol. Return #2633 is now accepted by trusted decision, overall final rung measured, with review IDs 705, 769, 1670; the prior #2989 statement that it was pending is historical. Review 1670 endorses proven only for the classical random-map theorem and finite-domain identities, excluding the source-limited Sasaki-Aoki discussion and any actual-MD5 hardness claim. No theorem or enumeration was rerun here.\n\nThe covering answer is unchanged. For N=16^32, p=16^-k and classical individual fresh queries without oracle-correlated advice, with preprocessing charged, the existing bound is success <= 1-(1-p)^min(q,N). The necessary conditional fresh-answer uniformity has not been established for fixed actual MD5. The existing #2657 coherent-access O(4^k) distinction is retained from #2989's comparison; #2657 and its unchanged reviews 715/777 were not fetched again. Thus this is no model-independent 16^k lower bound, no wall-time bound, and no closure of actual full-64-step MD5 on 32 literal lowercase hexadecimal ASCII bytes. The finite-domain no-solution issue and different meanings of average remain as stated in #2633. No candidate, fixed-point existence claim, speedup, new method, scientific acceptance or document integration is supplied by this return.\n\nRead the current work-state endpoint and supplied in-flight coordination. The work-state response contains only 50 recent decisions and does not include this older exact scope; adding limit=200 still returned 50, so this lookup does not independently certify present suppression. The observed prior return carries an effective covered decision, and this response is bound to the issued current input/scope hashes for the controller/server's freshness check. Lane lookup limitations are retained: /chat returned the channel directory, /chat/self-match returned 404, and /chat/messages with path or channel selectors returned the project channel (path empty), not self-match. No uninspected lane claims are represented as checked, and no chat is relied upon as scientific evidence or closure authority. There are no nominated message IDs in this assignment. This source-only delta check launched no expensive experiment or competing scientific work.\n\nReopen for a concrete model-proof defect, an actual-MD5 construction/theorem changing applicability, a new explicit resource-model obligation, or an assigned independent replication. No replication was performed or newly assigned. Scientific CPU 0 seconds, cpu_hours=0, zero MD5 evaluations, zero compute calls; administrative source parsing and hashing are unmeasured overhead. No coverage package was regenerated, and no route ID or structured research object is invented.
