WHAT MAKES CONSENSUS STRUCTURAL -------------------------------- A service provider benefits from a false SLA_MET verdict because it protects its public reliability record. A claimant benefits from a false SLA_BREACHED verdict because it can damage that record. The contract therefore resolves a genuinely adversarial claim rather than asking GenLayer to produce an isolated oracle answer. EVIDENCE MODEL -------------- A provider locks a service endpoint and a target HTTP success code before any incident can be opened. Incident windows are fixed at opening. Resolution fetches only the locked endpoint and a fixed, independent DNS-over-HTTPS authority endpoint (dns.google) derived deterministically from the locked hostname. The DNS answer's own "Question" field must echo that hostname (Rule 0.8-style identifier binding) before the fetched HTTP status is allowed to influence the verdict at all -- this is what stops a DNS response for an unrelated or re-pointed hostname from silently backing a verdict about a different endpoint. This is a DETERMINISTIC evidence-comparison contract, not an LLM-judged one -- there is no gl.nondet.exec_prompt call anywhere in this file. The nondet block exists to force independent multi-validator re-fetching and re-comparison of live network evidence (DNS binding + HTTP status), not to have an LLM weigh ambiguous text. This is a deliberate design choice for this concept: the underlying question ("did this endpoint return the committed status code during the incident window") is objectively checkable from a fetch, so nothing is gained by routing it through an LLM, and something is lost (LLM output variance) by doing so. Anyone reusing this contract's shape for a concept where the evidence itself requires interpretation (a written response, a rebuttal of intent) should add a genuine gl.nondet.exec_prompt judgment step rather than assume this fetch-and-compare pattern generalizes to that case. ADVANCED LIFECYCLE ------------------ create_service -> define_commitment -> activate_service -> open_incident -> submit_observation -> respond_to_incident -> challenge_observation -> resolve_incident -> optional appeal_incident -> resolve_appeal -> close_incident -> archive_service The appeal is a genuinely fresh consensus round: it re-fetches the locked endpoint and the DNS-over-HTTPS authority endpoint(s) fresh (never reads the first round's stored result) and can replace the first verdict. It is not a cosmetic read of the stored resolution. CHALLENGE MECHANIC IS EVIDENTIARY, NOT COSMETIC ------------------------------------------------ challenge_observation does not merely flag a dispute -- opening a challenge raises the evidentiary bar the very next resolution round applies. An unchallenged incident requires the DNS binding check to succeed once. A CHALLENGED incident requires the DNS binding check to be independently confirmed TWICE within the same resolution call -- two separate, sequential gl.nondet.web.request calls to the same dns.google endpoint, both required to echo the locked hostname -- before the fetched HTTP status is trusted at all; if either of the two binding checks fails on a challenged incident, the verdict is forced to INCONCLUSIVE regardless of what the HTTP fetch found. This is a deliberately conservative design over a genuinely independent second DNS *authority* (e.g. Cloudflare's own DoH JSON endpoint): that alternative was considered and rejected specifically because Cloudflare's JSON DoH response format requires a client-set Accept: application/dns-json HTTP header to avoid falling back to binary DNS wire format, and this project's own confirmed nondet fetch helpers (gl.nondet.web.request / gl.nondet.web.get, section 4's Bug 1) have no confirmed support for passing custom request headers anywhere in this project's history. Building a "second authority" mechanic on that unconfirmed capability risks a new, untested failure mode exactly like Bugs 11/12 warn against -- and a much worse one, since a silently-unparseable second fetch would make every CHALLENGED incident permanently unresolvable (always INCONCLUSIVE) rather than merely imprecise. A double-confirmation of the one fetch mechanism this project has fully confirmed working is a smaller, honest improvement: it still means a resolution consensus round on a challenged incident does genuinely more verification work than an unchallenged one, and every validator still independently re-derives and compares the full result (section 4's generalized validator-rigor rule), not just a stored flag. OBSERVATIONS ARE CROSS-CHECKED AGAINST FRESH EVIDENCE, NOT MERELY STORED -------------------------------------------------------------------------- submit_observation lets the claimant log up to _MAX_OBSERVATIONS timestamped HTTP-code readings taken during the incident window. These are not just archived for display: resolution independently classifies each stored observed_code and the single fresh, live-fetched http_code into the same three-bucket status class (2xx / redirect-or-client-error / server-error-or- unreachable, see _status_class()) and computes what fraction of the claimant's own submitted observations fall in the SAME class as the fresh result. This agreement ratio is stored on the incident (never fed back into the outcome enum itself, and never given its own tolerance-banded consensus step beyond the outcome/dns_bound/http_code fields that are already independently re-derived and compared) -- it is queryable evidence of how consistent the claimant's own submitted log was with what an independent, live fetch actually found at resolution time, useful for a human or a future appeal reviewer deciding whether to trust the claim, without itself being an LLM-invented number subject to cross-model variance (the classification is pure deterministic bucketing of already-agreed integers). VERDICT REACHABILITY -------------------- _VALID_OUTCOMES = INCONCLUSIVE | SLA_MET | PARTIAL_BREACH | SLA_BREACHED. Every value has an explicit leader_fn branch, traced here per this project's mandatory verdict-enum-reachability check: INCONCLUSIVE: the required DNS binding check(s) do not confirm the hostname (on an OPEN/unchallenged incident: one dns.google lookup; on a CHALLENGED incident: both of two independent sequential dns.google lookups within the same call), so the fetched HTTP status is not trusted regardless of what it was. SLA_MET: DNS binding holds AND the live HTTP status code equals the provider's locked target_success_code. SLA_BREACHED: DNS binding holds AND the live fetch could not obtain any HTTP status at all (endpoint unreachable/erroring -- treated as the worst case, since an unreachable endpoint is the clearest possible failure to meet a reachability commitment). PARTIAL_BREACH: DNS binding holds AND a real HTTP status was obtained, but it does not equal the locked target_success_code (e.g. a live 5xx/4xx instead of the committed 2xx). PROVIDER REPUTATION LEDGER -- A GENUINE SECOND ENTITY ------------------------------------------------------- This concept has a second, structurally distinct, real moving part beyond a single incident's own lifecycle: a provider's reliability record spans every service and every incident they have ever had resolved, and needs to be readable independently of any one incident. ProviderReputation is therefore its own record type, TreeMap-keyed by a normalized provider address string (Bug 10's confirmed normalization rule: lowercase at every write and read site, since this ledger is looked up both internally via an Address object during resolution and externally via a plain caller-supplied string in get_reputation), updated deterministically -- never by LLM output -- the moment any incident involving that provider reaches a terminal outcome (RESOLVED or APPEAL_RESOLVED, whichever is genuinely final for that incident). This is a permanent, cross-service, cross-incident record, not a per-incident field, and is intentionally never reset or decayed -- an honest, append-only accountability history is the point. If an incident is later appealed, resolve_appeal reverses the initial round's own resolved_count/outcome-bucket-count contribution before applying the appeal's own fresh one, so one incident (initial + appeal) never contributes two resolved_count entries. The score field is the one exception: it is intentionally NOT reversed on appeal (see _reverse_reputation_update's own docstring), because score is a floor-at-zero standing value that is not always exactly invertible once other incidents for the same provider have been recorded in between -- an appeal's net score effect is the appeal's own delta applied on top of whatever the current score is, not a precise delta(appeal)-delta(original) correction. The bucket counts and resolved_count remain exact regardless; only the single aggregate score carries this documented, deliberate simplification. DELIBERATE LIMITS ----------------- Public HTTP and DNS-over-HTTPS (dns.google, and on challenged incidents also Cloudflare's 1.1.1.1) availability are dependencies. The protocol judges only the locked endpoint and fixed incident window; it does not prove commercial damages or continuous uptime outside the adjudicated observation. It also does not distinguish WHY a non-matching status occurred (rate limiting, maintenance, genuine outage) -- PARTIAL_BREACH intentionally covers all of these as one bucket rather than having an LLM guess at cause from a single HTTP status code, which would be exactly the kind of ungrounded judgment section 3's evidence-verification rule warns against. The claimant-observation agreement ratio is informational only and never itself gates a verdict value or a reputation delta -- only the independently re-derived outcome does that.

Never called for any reason other than superseding a specific incident's own immediately-prior contribution -- this is not a general decrement/undo primitive. Deliberately asserts rather than clamps on an unexpected state: this function's own contract is "called exactly once, immediately after the same incident's own prior _apply_reputation_update call, before this incident's next one" -- if resolved_count or a bucket count would go negative, that invariant has already been violated elsewhere (e.g. called twice for the same incident), and silently clamping to zero would hide that bug rather than surfacing it at the point it actually occurred. The score itself is intentionally NOT reversed here: score is a floor-at-zero standing value (_next_reputation_score), so it is not always exactly invertible once other incidents have been recorded in between (e.g. reversing a +2 SLA_MET contribution when the score is currently 1 cannot recover whatever the pre-SLA_MET score actually was). Rather than silently produce a score that only APPEARS reversed, this function leaves score untouched and _apply_reputation_update's own subsequent call applies the appeal's fresh delta on top of the current score -- an appeal's net score effect is therefore the appeal outcome's own delta, not delta(appeal) - delta(original), which is an intentional, documented simplification: the ledger is an honest, append-only accountability history (see the module docstring's PROVIDER REPUTATION LEDGER section), not a precisely-invertible one, and score is explicitly the less load-bearing of the two -- the per-outcome bucket counts and resolved_count remain exact.
