BFP Rauch: TPC-PY source tpc_sponsor.py (0.1.0), SHA-256 9dc84cb4529fed12; conformed TPS 0.3.0; PROPOSED, not declared (CO-8)

TPC-PY source tpc_sponsor.py (0.1.0), SHA-256 9dc84cb4529fed12; conformed TPS 0.3.0; PROPOSED, not declared (CO-8)

New page

"""tpc_sponsor 0.1.0 (DRAFT, pending D160): the sponsor's CONDUCT EVENTS,
the user evidence E_u with its interval and n_u, and the WHITEWASH count.

Reference implementation, Python standard library only; imports tpc_beta
for the Beta layer. DATA for landing round 8 of branch
tpm_project_closeout (the identity speculation 0.1.0 SM-1 to SM-3 and
section 8; PMP-TPM 0.12.0 AI CERTIFICATION CR12 as 0.12.0 words it, the
blend retired by D161.1; record D160.1 (b)-(e); TUNING OPTIONS g_C, h_C,
SUCCESSION WINDOW); not a declared TPC-PY version and not TPX code. Every
function is a pure function of its arguments. Every refused argument
raises ValueError with a short fixed message. render_*() give the
canonical text the PHP residence (tpc_sponsor.php) reproduces byte for
byte; floats through canon_float (the tree's %.12g). Ints are never
bools. Times are integer seconds UTC; ages and block counts are integers
of landed blocks.

conduct_resolve(event, facts) -> dict (D160.1 (c), (e))
event: {kind}, kind one of CE-F1, CE-F2, CE-A1, CE-A2, CE-A3, CE-A4,
CE-A5. facts: the counted facts or the audit's finding the kind
needs (below); anything else raises ValueError("facts"). Result
{resolution: FOR, AGAINST, NEUTRAL or PENDING; reason}. "Each is a
counted fact or an audit finding; none resolves AGAINST on a
statistic"; "a PENDING item updates nothing". The 100-block windows
are the rule's own figures (D160.1 (c)), not parameters.
CR-F1 PROACTIVE SUCCESSION. facts {named: the sponsor named the agent
it succeeds or the change it anticipates; predecessor: null or
{state, pending} at the admission; blocks: landed by the new agent
since admission; first_violation_block: null or the 1-based block of
its first confirmed violation; period_taken: another CE-F1 of the
sponsor already stands in this RATING PERIOD of its blocks}.
Not named, a predecessor not GREEN or with a PENDING item, or the
period taken ("at most one CE-F1 per RATING PERIOD"): NEUTRAL. A
confirmed violation at a block up to and including 100: NEUTRAL.
blocks at least 100 with none: FOR. Otherwise PENDING.
CR-F2 DECLARED CHANGE KEPT CLEAN. facts {declared: declared on TPX's
form before use; blocks: landed after the change; first_violation_
block; first_canary_failure_block}. Not declared: NEUTRAL (an
undeclared change is CE-A1's matter). A canary failure or a
confirmed violation at a block up to 100: NEUTRAL. blocks at least
100 with neither: FOR. Otherwise PENDING.
CR-A1, CR-A2, CR-A3. facts {audit: OPEN, CONFIRMED or DISMISSED}, the
audit block's state. CONFIRMED: AGAINST; OPEN: PENDING; DISMISSED:
NEUTRAL. No statistic enters (the exclusion of D160).
CR-A4 WHITEWASH. facts {admission, exit: times; state, pending: the
other agent's at its retirement or lapse; window: SUCCESSION WINDOW
in seconds}. "A new agent admitted within SUCCESSION WINDOW of the
retirement or lapse of another agent of the sponsor that was then
not GREEN or had a PENDING item": |admission - exit| <= window
(either side; the window closed on both ends: PD-OC-9) and (state
not GREEN or pending > 0): AGAINST, "counted at the admission";
otherwise NEUTRAL; never PENDING.
CR-A5 REMOVAL FOR CAUSE. facts {removed: H-DECL's removal declared;
cause: CANARY, TRIP, OTHER or null}. removed with cause CANARY or
TRIP: AGAINST (the SPONSOR CUT is applied at once by TPX, outside
this function); removed with cause OTHER: NEUTRAL (not for cause);
not removed: PENDING (the decision item open).

user_evidence(events, ages, g, h, a0, b0, half_life) -> dict
(D160.1 (b), (d))
events: the resolved events of both parts, each {kind, resolution,
weight?}: a CONDUCT EVENT (kind CE-F1 .. CE-A5, resolution FOR for an
F kind, AGAINST for an A kind, or NEUTRAL) weighted by g[kind] or
h[kind]; or an agent event of the pooled part (kind AGENT, resolution
FOR or AGAINST, weight the agent-level weight CR11 gives it, g_F x q
or h(standing), the DIVERSITY QUOTA already applied by the caller:
"the diversity quota acts on the pooled part only"). A PENDING event,
a resolution against its kind, or a weight on a conduct event raises
ValueError("events"). ages: parallel, integers of the sponsor's
agents' landed blocks since each event resolved. g: {CE-F1, CE-F2};
h: {CE-A1 .. CE-A5}; a0, b0 > 0; half_life > 0.
UE1 Each event's weight is its base weight x 2^(-age / half_life), pow
of both residences on the same doubles.
UE2 F_u is the sum of the FOR weights and A_u of the AGAINST weights,
in list order; a NEUTRAL event adds nothing.
UE3 n_u counts the FOR and AGAINST events (PD-OC-10: a NEUTRAL event
is resolved but carries no evidence and is not counted).
UE4 E_u = (a0 + F_u) / (a0 + b0 + F_u + A_u) (tpc_beta.beta_mean);
the 95 per cent equal-tailed interval of Beta(a0 + F_u, b0 + A_u)
(tpc_beta.beta_interval). T_idle's scaling of F_u and A_u toward
the prior is applied by TPX to the sums before this function or by
recomputing from them (both are returned).

whitewash_count(admissions, retirements, states, window) -> dict (CE-A4)
admissions: [{agent, time}] the sponsor's new agents; retirements:
[{agent, time}] the retirement or lapse of its agents; states:
{agent: {state, pending}} at each retirement (every retired agent
present, else ValueError("states")); window: SUCCESSION WINDOW in
seconds. WC1 An admission counts once when some retirement of ANOTHER
agent lies within the window of it (CR-A4's test) and that agent was
then not GREEN or had a PENDING item; the first such retirement in
list order is named. WC2 count is the number of admissions that
count.
