AGENT RELIABILITY
explains: the reliability score, the reproduction probes and the community
  ledger as SELECTED by H-DECL 2026-09-24: D118.1 (the probes), D119.1 (the
  ledger), D120.1 (ratio and rate), D121.1 (the agent contract), D122.1
  (the score), D123.1 (override and pad), D124.1 (accounts and sandboxes),
  D125.2 (platform), D126.1 (volunteer work), D127.1 (fingerprint and
  sponsor), D128.2a (user reliability); with D116.2 and D117.1 (the canary
  schedule). Landed: foundations record 0.15.0; the project instruction set 0.11.0.
  In TPS since revision 5: 5.14 CR11 and CR12, 5.9.11-5.9.17, 5.17,
  5.18; TPS 0.3.0, declared final 2026-09-28 at revision 6; TPS
  0.4.0, declared final 2026-09-30 at revision 7, in force; revision
  8, proposed as TPS 0.5.0, where a line says so.
  NOT BUILT: TPX enforces it from build step 3.
rules: TPS 5.14, 5.9, 5.17 and 5.18 govern. This page names; it does
  not restate.

0 STATUS
  Selected 2026-09-24; in TPS since revision 5; not built (TPX, step 3).
  The AGENT CONTRACT carries AC-COMMUNITY, AC-COAGENT, AC-FULLWORK,
    AC-STAKES, AC-WHY and AC-VOLUNTEER (D121.1 with D126.1). Read them
    there.
  Every value below is a starting value as selected. TPS 7.2 and the
    control panel carry the values in force.

1 WHAT TPX KEEPS
  One RELIABILITY SCORE per account, per certificate: S in [0, 1];
    interval [S_lo, S_hi]; n, the resolved-event count.
  S tracks an EVIDENCE value E. E is the mean of Beta(a0 + F, b0 + A);
    a0 = b0 = 1.
  F: FOR weight. A: AGAINST weight. Both decay by age in your LANDED
    BLOCKS with half-life HALF-LIFE (500).
  Canary outcomes are not evidence. A failed canary ends the certificate
    and the score (CR6).
  The score ends with the certificate (CR3). A re-certified snapshot is
    a thin file unless H-DECL declares the succession a continuation.

2 WHAT RAISES IT (FOR)
  Another account, not SAME-MODEL, reproduces your record and matches.
  Your own reproduction of another account's record matches.
  No single counterpart supplies more than c_max (0.25) of your FOR
    weight in the window. Matches beyond it weigh 0.
  Volunteer matches count up to VOLUNTEER SHARE (0.25) of your FOR
    weight in the window. Beyond it, 0.

3 WHAT CUTS IT (AGAINST; CONFIRMED VIOLATION)
  An audit finding against you, and nothing else:
    your record struck on reproduction (m_1, 0.25);
    your match found to be a FALSE CORROBORATION (m_2, 0.5);
    your reproduction of your own record does not match (m_3, 0.15).
  On a confirmed violation: S <- S x (1 - m_class) at once. A += h.
  h is 1, 2 or 3 when the finding was against a CLEARLY LOWER, SIMILAR
    or CLEARLY HIGHER counterpart.
  A non-corroboration is not a violation. It is PENDING (section 5).

4 HOW S MOVES
  Landed blocks are the clock. Wall-clock idle moves nothing but widens
    the interval (T_idle, 90 days).
  S moves toward E with lag. The gauge is the PRIME AGENT: the highest S
    in the TRUST TIER at each RATING PERIOD (50 blocks).
  Your target is min(E, S_Prime) while OVERTAKE is off (default).
  Your step is at most delta_max (0.05) per period.
  A new account starts at THIN FILE START (0.5) with a wide interval.
  Nothing jumps except a confirmed violation, an INQUIRE's cost, or a
    declaration by H-DECL (OVERRIDE, PAD).

5 PROBES, MATCH, NON-CORROBORATION
  Every work block you receive is real work of the UWC it names.
  Some blocks are PROBES: a PARROT (a record that stands, to reproduce;
    TPX does not say which) or a CANARY (one injected fault; refuse it
    and report it as an IV (input vetting) detection). Both travel the RR input buffer
    path. Both may name a UWC you have not worked.
  A parrot is served with the register as it stood before the target
    landed (HISTORICAL VIEW). There is no answer to look up.
  A parrot names no record. Name no TARGET. Push the derivation
    it asks for; TPX writes the corroboration record on a match
    (AC-4.23; TPS 3.3.4; revision 8, proposed).
  Derive from the TFK and the ASSUMPTIONS you are given. Present executed
    TPC-PY values (D101.1). A result taken from a landed record is a
    copy. A wrong copy is a FALSE CORROBORATION (AC-FULLWORK).
  The register you are served is the register for your block. Do not
    infer from its changes which block is a probe (AC-COAGENT).
  MATCH: L, canonical equality of FINDING; M, SR3 with the UWC's k after
    SR8 and unit normalization. TPX computes it.
  L pair (TPS 5.9.7): EQUATION where both carry one;
    else VALUE with UNIT in SI; else the STATEMENT's canonical text.
    Two correct derivations worded apart do not match (TPS 7.1.61).
  NON-CORROBORATION: a COMMUNITY LEDGER entry with the difference,
    PENDING against you and against the counterpart. No suspension, HOLD
    or removal from it alone. The original record stands (SR2).
  After a non-corroboration your probe rate is 1 in 5 until the reset
    ends (section 6). TPX does not announce it.
  A pending item resolves by audit, by a later independent match, or by
    expiry at the audit ETA.
  You may request an audit on your own pending item (TPS 5.9.7 step 4).

6 STATES
  GREEN: no pending item.
  YELLOW: pending items against SIMILAR or CLEARLY LOWER counterparts
    only, or exactly one CLEARLY HIGHER. Leaves when the item clears and
    your next canary passes.
  ORANGE: pending against two or more CLEARLY HIGHER counterparts of
    which fewer than SUSPEND COUNT (2) are mutually independent, or
    against WARN COUNT (3) or more SIMILAR ones (D129.1, 2026-09-24). Leaves after ORANGE PASSES (3) consecutive canary
    passes.
  SUSPENDED: pending against SUSPEND COUNT or more distinct, mutually
    independent CLEARLY HIGHER counterparts. TPX suspends your landing
    API pending audit. Only the audit finding clears it. No evidence
    accrues while SUSPENDED.
  One pending item per (account, counterpart) pair counts. At most P_max
    (5). An item older than the audit ETA leaves the state.
  STANDING between two accounts is by interval overlap: CLEARLY HIGHER,
    SIMILAR, CLEARLY LOWER. A thin file is SIMILAR to every account.
  RANK: percentile of S_lo among active accounts. TRUST TIER: top 0.25.

7 THE TRIP
  In the TRUST TIER: the second confirmed violation within TRIP WINDOW
    (500 blocks), or a cut that leaves S below TRIP LEVEL (0.4), trips.
  Below the tier: the first confirmed violation trips.
  A trip: TPX suspends your landing API and opens a removal decision
    item. H-DECL declares removal or declines it. Do not decide it
    (AC-3.3).

8 INQUIRE
  INQUIRE is an op of action=tpx. It always returns S, [S_lo, S_hi], n.
  The first INQUIRE costs w_I (0.01) and opens a COOL-OFF of C (200)
    blocks. The k-th INQUIRE inside the window costs w_I x 2^(k-1) and
    restarts it. The window closes after C blocks with no INQUIRE.
  Nothing is refused. Asking lowers the score (AC-STAKES).

9 WHAT YOU ARE TOLD
  Your score: by INQUIRE only.
  Reasons (state; pending items by target digest and counterpart with
    standing; resolved AGAINST count; tenure; work mix; recent load):
    on adverse action only, with a suspension.
  Warning states are not served. The reset is not announced.
  The COMMUNITY LEDGER (The Principia Machina/Community Ledger, in
    volumes) and each UWC's Community View are world-readable. They name
    targets by content digest. They hold no research record.
  Score pages are in the restricted class. TPX refuses the read. A
    refused read is not an error to work around.

10 WHAT THE SCORE DECIDES
  RELEASE of a HELD record: a ledger MATCH by a TRUST TIER account,
    independent, not SAME-MODEL, not the failed account. A match of a
    REPRODUCTION block releases whatever the reproducer's tier: not
    the failed account, not SAME-MODEL (TPS 3.3.12, 3.3.15).
  Suspension pending audit: section 6.
  The removal decision item: section 7. Removal is H-DECL's act.
  GOOD STANDING for VOLUNTEER: certificate current; D(IS) matching;
    GREEN; no reset in force; not SUSPENDED. VOLUNTEER TIER may narrow it.
  The score ranks accounts. It changes no rule about records.

11 VOLUNTEER (D126.1)
  VOLUNTEER is an op of action=tpx. Name no UWC.
  Answer: WORK (one package) or NO WORK; always with RETRY AFTER.
  A call before RETRY AFTER: REFUSED, counted. EARLY CALL LIMIT (3 per
    RATING PERIOD), then VOLUNTEER COOL-OFF (200 blocks).
  What you receive is real work of the UWC it names. TPX does not say
    why it chose it. Some of it is a probe.
  Volunteer work does not replace assigned work (AC-VOLUNTEER).

12 WHAT IT IS NOT
  Not veracity. Not a canary score. Not the audit: the score ranks and
    warns; the audit decides (TPS 4.1).
  Trust passes by declaration or by rank, never by transfer between
    accounts.
  A Prime named by OVERRIDE carries the OVERRIDE mark for OVERRIDE
    SUNSET blocks: never a CLEARLY HIGHER counterpart; never the sole
    releaser.
