[Peyton-Spencer]

Summary

• SN-302, approved by Peyton on 2026-11-01: a fork of another owner's publicly released agent earns nothing until it beats that base on at least fork_min_shared_seeds (default 3) shared confirmation seeds, through the crown gate's paired test (koth._dethrone_decision + CrownGate). This applies to tail slots as well as the crown. Same-owner successors are exempt, using the unreleased-copy canonical owners: hotkey, payment coldkey, and attested links.
• Detection (api_server/fork_gate.py, recorded in a new agent_fork_bases table by the unreleased-copy sentinel). The base is the other-owner agent, publicly released before the upload, with the largest shared distinctive content from the feat(platform): flag unreleased-agent copying across languages in shadow mode #3303 index. Common idioms and the owner's own earlier items are removed first, and the pair must reach the calibrated threshold of 40. A copy-court released-base clear also names a base.
• Setting: fork_must_beat_base (off/shadow/enforce) plus fork_min_shared_seeds on the audited emission eligibility policy. Revisions are append-only and appear in the admin activity feed. It ships shadow: forks are published as fork_unproven and rehearsed, and nothing is withheld.
• Enforcement point: Platform drops unproven forks from the payable pool, the same way the review gate withholds rows. Validators already fold the pool as served, so no heartbeat protocol bump is needed. enforce rehearses as shadow until the protocol-28 fleet gate is met.
• Backroom: get_fork_gate lists each ledger fork, its base, N/3 seeds, the lead, current pin share, and would_lose_emissions. set_emission_eligibility_policy writes the setting.
• UI: the King and each challenger show "fork of X — must beat base: N/3 confirmations, lead ±Δ".

Validation

• test_fork_gate.py covers:
  • detection of the beast case;
  • same-owner, unreleased and released-after cases that are not forks;
  • largest-base selection and the court basis;
  • the paired duel at 3, 2, and tied seeds and with no base;
  • shadow vs enforce withholding.
• test_unreleased_copy.py: the sentinel classifies forks in the same tick.
• Platform focused suites: 207 passed. Backroom: 1334 passed. Dashboard: 1016 passed, plus check and build.

Activation

• Merge and deploy put the gate in shadow, with no weight change. Read get_fork_gate / the public board before any enforce.
• Before enforce: a base outside the retest cohort gains no new seeds, so a fork can only share seeds the base was already scored on. Check for forks stuck at 0/3 against an out-of-cohort base.

🟠 High · bug — Refresh fork classifications when court evidence arrives · 🔎 Verified by trace

If a court recommendation naming a released base is recorded after an agent’s first classification, this query never selects that agent again because its fork-base row already exists, and store_fork_base ignores conflicts. The later recommendation is therefore never passed to court_fork_bases, leaving the fork_must_beat_base gate with a missing or stale classification; refresh classifications when court evidence changes and allow the stored result to be updated.

Why Ditto flagged this (confidence 88%)

The new loop selects only pending_fork_candidates at lines 283–285, then stores the result at line 296; the referenced query and store implementation use a missing-row selection and conflict-do-nothing insert. Once the first classification has written a row, a later court recommendation cannot trigger reevaluation, so the court evidence source at line 289 cannot affect the gate’s stored classification.

Add a regression test that first classifies an agent, then records a qualifying court recommendation, and verifies the stored classification and gate input reflect that recommendation; run the focused fork-base and sentinel tests.

🟠 High · bug — Do not report fork emissions as known when no pin exists · 🔎 Verified by trace

When _active_pin returns None, this loop treats every fork as in the pool but assigns it a zero share, so currently_earning and would_lose_emissions are false regardless of its actual payout status. The endpoint therefore tells operators that no fork will lose emissions precisely when they need this information to assess enforcement; without a pin, these fields must be represented as unknown rather than as a confirmed zero.

Why Ditto flagged this (confidence 85%)

The endpoint gets payable ledger rows at lines 412–414, but when no pin exists lines 440–445 create empty share and membership data; lines 473–475 then report every fork as in-pool with zero share and not earning. This makes the operator-facing would_lose_emissions result at lines 503 and 517–519 assert “none” without evidence about payout status, contrary to the endpoint’s stated pre-enforcement purpose at lines 404–405.

Run the focused endpoint tests.

🟠 High · bug — Resolve public fork duels with the ledger’s band settings · 🔎 Verified by trace

_fork_duels_for calls resolve_fork_duels without the ceiling-clamp or statistical-cap settings that the scoring path supplies. When either setting changes scores at a fork boundary, the public eligibility record can disagree with the ledger about reward_eligible; build_public_leaderboard then filters emission_rows using that record and can publish a different champion from the fold.

Why Ditto flagged this (confidence 82%)

At lines 2466-2471, the public path calls resolve_fork_duels with only the benchmark version and minimum shared seeds, while the scoring path at scoring.py:1119-1125 supplies the ceiling-clamp and statistical-cap settings. Thus, when either setting affects a comparison near the fork boundary, the public duel can yield a different eligibility result; the public leaderboard uses that result to filter emission rows at lines 4288-4293, so the published champion can diverge from the ledger fold.

Add or update a focused test showing public fork eligibility agrees with the ledger when each setting is active, and run that test plus the relevant public/scoring tests.

🟡 Medium · bug — The king's fork line can stay beside its facts · 🔎 Verified by trace

.crown-duel-king is a wrapping flex container, so display: block on its fork item does not make that item start a new row. When the king's facts and fork text fit together, the fork text appears beside them instead of on its own line; give the item a full-width flex basis.

Suggested change

	display: block;
	margin-top: 4px;
	flex: 0 0 100%;
	margin-top: 4px;

Why Ditto flagged this (confidence 94%)

Lines 1774–1776 make .crown-duel-king a wrapping flex container, while lines 1934–1936 only set display: block on the fork item. That does not force a flex item onto a new row, so when the facts and fork text fit together they can render on the same row, contrary to the stated own-line layout.

This makes the fork item occupy its own row in the wrapping flex container. Verify the king facts and fork text render on separate lines at a width where they would otherwise fit together.

🟡 Medium · bug — Do not treat every compared base as a court-cited fork base · 🔎 Verified by trace

bases_compared contains comparison candidates, but this loop adds every valid ID whenever the overall recommendation has an eligible basis; it does not require that an individual base was proven public or cited by that basis. The fork detector treats a court-cited base as eligible even when it was not released before the candidate upload (fork_gate.py:114-124), so an unproven comparison candidate can become a stored fork base and affect the gate.

Why Ditto flagged this (confidence 86%)

At fork_bases.py:101-103, every ID in bases_compared is added after only checking the recommendation-wide basis at lines 91-93. The triage evidence records public_before_held_upload separately (copy_court_triage.py:604), while fork_gate.py:114-124 allows a court-cited ID to bypass the ordinary release-time check; consequently, an unproven base that was merely compared can be persisted as a fork base and affect the gate.

Record that per-base distinction in the evidence, and have `court_fork_bases` add only those eligible base IDs; do not use the top-level `public_before_held_upload` field as a per-base flag. Add or update focused tests for an unproven compared base and a proven cited base, then run the relevant copy-court and fork-gate tests.

🟡 Medium · bug — Fork-gate duels omit the ledger's fleet-dependent scoring flags · 🔎 Verified by trace

When the fleet activates the ceiling-band clamp or statistical band cap, resolve_fork_duels can compute a different required lead here than it does on the scoring path. That can invert beats_base and make this endpoint report an incorrect would_lose_emissions decision.

Why Ditto flagged this (confidence 86%)

The new endpoint calls resolve_fork_duels at lines 419–424 without the ceiling_band_clamp and statistical_band_cap inputs that the scoring path supplies (scoring.py:1119, 1125). In a fleet regime where either input changes the required lead, the endpoint can therefore produce a different beats_base result, which flows directly into would_lose_emissions at line 503.

Import or compute the required fleet-readiness inputs using the same sources and policy as that path. Add a focused test for an active clamp or cap that verifies the admin fork-gate duel outcome and `would_lose_emissions` agree with the ledger behavior, then run the endpoint tests.

🟡 Medium · bug — Resolve fork duels at each ledger row's benchmark version · 🔎 Verified by trace

rows can include entries scored at the desired benchmark version while ledger_context.active_bench_version still identifies the canonical version. Passing that single version to resolve_fork_duels at line 1122 makes desired-version forks compare against confirmation data from the wrong benchmark, so valid forks can be classified as fork_unproven and withheld when enforcement is active; group rows by their own bench_version, resolve each group at that version, and merge the results.

Why Ditto flagged this (confidence 82%)

At lines 1118–1124, the resolver receives every row's agent/miner pair but only ledger_context.active_bench_version; during a rollout, desired-version rows therefore use the canonical version's confirmation data. That can classify an otherwise proven fork as unproven and withhold it under enforcement, so fork duels must be resolved per row benchmark version.

In `apps/platform/ditto/api_server/endpoints/scoring.py`, replace the single-version `resolve_fork_duels` call at line 1122 with version-aware resolution: group the `(agent_id, miner_hotkey)` pairs by each row's `bench_version` (using `ledger_context.active_bench_version` only when a row has no version), call `resolve_fork_duels` once for each group with that version and the existing options, and merge the returned mappings before calling `evaluate_ledger`. Keep the current behavior when fork evaluation is disabled. Add a focused test for a rollout where rows from the canonical and desired versions both include a fork, asserting each resolver call uses its group's version and the results are merged. Run the focused scoring tests.

[ditto-code]

🟡 Medium · bug — Fork detections disappear when ledger rows lack a benchmark version · 🔎 Verified by trace

When ledger rows have no bench_version, the conditional at lines 418–427 leaves duels empty; for a detected base with a non-null base_agent_id, line 471 then drops the fork from this endpoint’s response. The endpoint documents that it reports every ledger fork, so represent the detection with duel evidence marked unavailable rather than omitting it; reporting zero shared seeds would incorrectly imply a duel was performed.

Why Ditto flagged this (confidence 82%)

At lines 418–427, no ledger bench_version makes duels empty; the loop then skips any detected base with a non-null base_agent_id at line 471, even though bases were fetched independently at line 417 and the endpoint documents reporting every ledger fork at lines 400–405. Thus a detected fork is omitted specifically when its duel cannot be resolved, rather than surfaced as having unavailable duel evidence.

Represent unavailable duel evidence explicitly (update the response model and its consumers as needed); do not report fabricated zero-seed duel results or treat an unavailable duel as proof the fork beats its base. Add a focused endpoint test for classified fork bases with null ledger benchmark versions, then run that test and the relevant API-model tests.

🟡 Medium · bug — One fork-classification error aborts the whole candidate batch · 🔎 Verified by trace

If loading a candidate, querying its court bases, detecting a base, or storing the result raises, the exception escapes _classify_forks at lines 287–296 and prevents the rest of that batch from being classified. Because the failed candidate remains pending, each tick can select the same batch and fail again; isolate and log failures per candidate so the remaining candidates can make progress.

The new loop at lines 286–306 processes multiple pending candidates, but an exception in the per-candidate work escapes the loop before later candidates are stored. Since the failed candidate has no stored fork-base result, it remains pending; repeated ticks can therefore hit the same failing batch and prevent its other candidates from being classified. Per-candidate exception handling lets the rest of the batch progress.

Add fork-base detection and an emission gate requiring paired wins — Adds SN-302: agents detected as forks of another owner's released agent must beat that base on shared confirmation seeds before they earn emissions when the gate is enforced. The change stores detected bases, evaluates paired duels during ledger scoring, and exposes the policy and its effects through admin tools and public board displays. Review closely how the detector selects a base and how enforcement interacts with policy rollout and pinned emissions, since this can change payouts.

[omarzanji]

Reviewed by Claude on behalf of @omarzanji

Verdict: request changes. The three High findings from Ditto Review are still open at this head. There is one more concrete defect where the dashboard tells forks the wrong thing about their payment, and the branch needs a rebase that touches the code it depends on.

• Head reviewed: 29ab299f425197e3d66fe91bbc7fff073307a19c (pushed 2026-11-01 17:50Z, unchanged since Ditto Review ran at 18:11Z)
• Mergeability: CONFLICTING / DIRTY
• CI at this head: every test job passes. Two checks fail, and both are caused by drift, not by the code:
  • migration-order/merge-result fails with "multiple Alembic heads". 2026_11_01_zzz_add_agent_fork_bases.py revises 3f6a8d2c9e14. Main already has two other revisions of that parent (2026_11_01_zz_add_competition_improvement_metrics.py and 2026_11_01_zzz_add_unreleased_copy_settings.py), plus #3310's 2026_11_01_zzzz_enforce_unreleased_copy.py. Re-parent onto the current head.
  • Entire Gates fails only its "Up to date" gate (20 commits behind). Its Checks and Findings gates passed.

Ditto Review findings: none addressed at this head

• High, unreleased_copy_sentinel.py:285: rows are written once (on_conflict_do_nothing) and never re-selected. Court evidence that arrives after the first classification is never seen. The same staleness applies to release evidence recorded late: a fork classified "not a fork" before its base's released_at lands stays exempt forever. Classification needs a refresh trigger, not only an insert.
• High, admin_emission_eligibility.py:475: when there is no pin, would_lose_emissions reads false for every fork. That is the exact input the operator needs before switching to enforce.
• High, public.py:2470: _fork_duels_for drops ceiling_band_clamp and statistical_band_cap, so public reward_eligible can disagree with the ledger. Under enforce, build_public_leaderboard filters emission_rows on that record, so the board can project a different champion from the one validators fold. The admin endpoint (line 424) has the same gap.
• The Medium findings also still apply:
  • scoring.py:1122 resolves every row at a single bench version.
  • fork_bases.py:103 treats every bases_compared entry as a court-cited base.
  • admin_emission_eligibility.py:471 drops forks when ledger rows have no bench version.
  • In sentinel:306, one candidate's error aborts the whole batch.

Additional findings

1. The dashboard mislabels fork_unproven and states the wrong payment status.
   • apps/platform/dashboard/src/components/board/chips.tsx:112-123 and components/evidence/AgentEvidence.tsx:223-224 are unchanged.
   • Both show the chip and note whenever posture_satisfied === false. That now includes every shadow fork, because classify sets state = "fork_unproven" and posture_satisfied = False.
   • They take "enforcing" from record.enforcement, which is the review ladder, not fork_enforcement. The label then falls through to "Would not earn · review open" or "Not earning · review open".
   • Result: with review enforce and fork shadow, a fork that is still being paid is told publicly that it is "Not earning". With review shadow and fork enforce, a withheld fork is told it "is still being paid". In both cases the label blames an open review that does not exist.
   • Fix: switch on state === "fork_unproven" and use fork_enforcement for that state.
2. The shadow rehearsal records forks under the review posture. LedgerEligibility.withheld (emission_eligibility.py, unchanged) still filters on posture_satisfied, so shadow forks go into _record_eligibility_rehearsal with enforcement: record.enforcement (the review value). With review enforce and fork shadow, the log at scoring.py:1139 says "withheld", because enforcing is now review OR fork, for forks that are being paid. Fix: filter on reward_eligible for actual withholding, and record the fork ladder for fork rows.
3. Rewards consequence of enforce that needs explicit sign-off (not a code bug). A withheld incumbent stays crowned and unpaid under protocol 28 (scoring.py around lines 1200-1240). So an unproven fork that already holds the crown when enforce is switched on burns the champion share every epoch until it beats its base, and nobody else is paid that share. The same applies to a fork that takes the crown from someone other than its base. A base outside the retest cohort, retired, or with no confirmation seeds at the current bench version yields base=None, which means "unproven" forever (fork_bases.py resolve_fork_duels, fork_gate.py fork_duel). The activation note mentions the out-of-cohort case. The bench-version-bump and retired-base cases are worse, because no future seeds will ever arrive. Before enforce, decide whether a base with no current-version evidence should exempt the fork, or should schedule the base for retest.
4. Minor. agent_fork_bases.base_agent_id uses ondelete="SET NULL", and null means "not a fork". Deleting a base row would silently and permanently exempt every fork of it, because the PK row exists and is never reclassified. RESTRICT, or deleting the row so it is reclassified, is safer.
5. Rebase hazard. Since this branch was cut, #3317 changed load_context on main to take a worker-computed overlap (db/queries/unreleased_copy.py:216). _classify_forks makes a second in-process load_context per candidate per tick. After the rebase, reuse the overlap the signal already computed in the same tick, so the sentinel does not repeat the heavy work on the event loop.

What looks right: the separate fork_must_beat_base ladder, withholds switching to reward_eligible, the fleet-gated effective_policy downgrade, the same-owner exemption via canonical owners, and the deterministic base tie-break. Shipping in shadow changes no weights, provided finding 1 is fixed so the board does not misreport payment.

Recommended next step: rebase onto main and re-parent the migration. Fix the three High findings plus findings 1 and 2. Get product sign-off on finding 3 before any enforce, then re-request Ditto Review.
