00:00:00.000 --> 00:00:08.833
This overview explains how D through D7 connect task routing,
proved rules, caches, revision handling, and normalization.

2
00:00:08.833 --> 00:00:16.667
An operation saving can disappear after proof, matching,
preparation, execution, and delivery costs are charged.

3
00:00:16.967 --> 00:00:24.133
For input one zero zero, A and B gives zero and C is zero, so the output is zero.

4
00:00:24.133 --> 00:00:29.433
This point query has supplied all three inputs and returns one bit.

5
00:00:29.433 --> 00:00:33.900
Fixing only C to zero leaves a function of A and B.

6
00:00:33.900 --> 00:00:37.567
The answer is a residual rule, not a scalar bit.

7
00:00:37.567 --> 00:00:44.667
It remains necessary to supply A and B or evaluate the remaining assignments.

8
00:00:44.667 --> 00:00:50.633
At one zero the residual returns zero; at one one it returns one.

9
00:00:50.633 --> 00:00:55.433
The two different outputs demonstrate why the residual cannot be replaced by the single

10
00:00:55.433 --> 00:00:59.694
point result from the earlier request.

11
00:00:59.694 --> 00:00:59.700
point result from the earlier request.

12
00:00:59.700 --> 00:01:03.733
D through D7 move from task routing to proved rules,

13
00:01:03.733 --> 00:01:11.433
versioned caches, profitability gates, natural
incidence, real revisions and bounded normalization.

14
00:01:11.433 --> 00:01:15.733
The requested output determines which work can help.

15
00:01:15.733 --> 00:01:19.467
A point query asks for one decision.

16
00:01:19.467 --> 00:01:23.933
A restriction asks for the function under fixed inputs.

17
00:01:23.933 --> 00:01:28.133
A repeated-vector session can reuse preparation.

18
00:01:28.133 --> 00:01:33.267
A fresh full-vector request still pays construction and delivery.

19
00:01:33.267 --> 00:01:40.067
For a conceptual rule, factor role AND region, OR role
AND resource into role AND the OR of region and resource;

20
00:01:40.067 --> 00:01:45.967
verify all inputs, then charge discovery, matching, proof and replay.

21
00:01:45.967 --> 00:01:49.033
The retained D-series results are mixed:

22
00:01:49.033 --> 00:01:56.300
restrictions and repeated work could benefit while
complete-vector tasks and some proof paths lost.

23
00:01:56.300 --> 00:02:02.033
More exact machinery did not reliably create profitable whole requests.

24
00:02:02.033 --> 00:02:10.021
The conceptual policy identity illustrates proof; it
is not evidence of an actual deployed policy gain.

25
00:02:10.321 --> 00:02:14.458
Return to F equals A and B, or C.

26
00:02:14.458 --> 00:02:18.386
Fix only C to one and leave A and B free.

27
00:02:18.386 --> 00:02:22.453
This is a partial binding, not a complete three-input assignment.

28
00:02:22.453 --> 00:02:30.291
The remaining inputs zero zero, zero one, one zero and one one will all return one.

29
00:02:31.041 --> 00:02:37.104
Fixing C to one makes the outer or true for every remaining A and B assignment.

30
00:02:37.104 --> 00:02:40.649
The residual function is therefore the constant one.

31
00:02:40.649 --> 00:02:48.075
This restriction is different from fixing C to zero, which left the nonconstant function A and B.

32
00:02:48.375 --> 00:02:55.669
Fixing C to one collapses this residual to constant one for all four assignments of A and B.

33
00:02:55.669 --> 00:03:03.010
A restriction returns a remaining function; a complete assignment supplies A, B and C and returns one bit.

34
00:03:03.010 --> 00:03:08.595
Keep the parent rule and the fixed binding attached to the residual.

35
00:03:08.894 --> 00:03:13.727
For each assignment with C one, the final or returns one.

36
00:03:13.727 --> 00:03:17.861
When C is zero, the result is A and B.

37
00:03:17.861 --> 00:03:24.261
Interleaving those cases in zero-first binary order gives the displayed eight outputs.

38
00:03:24.261 --> 00:03:28.094
Every requested output is present.

39
00:03:28.094 --> 00:03:33.327
A resident object can avoid repeated preparation, but the caller may still require the

40
00:03:33.327 --> 00:03:36.127
vector to be delivered on every read.

41
00:03:36.127 --> 00:03:43.127
Account for the work actually owed rather than assuming residency eliminates all cost.

42
00:03:43.127 --> 00:03:49.361
A revised source can invalidate a prepared artifact or proof attached to the old rule.

43
00:03:49.361 --> 00:03:55.527
Matching, verifying, updating, and executing the replacement all cost work.

44
00:03:55.527 --> 00:04:02.194
Whether that overhead is repaid depends on the request and reuse lifetime.

45
00:04:02.194 --> 00:04:02.199
Evaluate the complete required request.

46
00:04:02.199 --> 00:04:06.127
Evaluate the complete required request.

47
00:04:06.127 --> 00:04:14.994
Keep task-specific gains and losses separate rather than
treating more exact machinery as a universal speedup.
