Crucible Emergent Resurrection

Emergent Resurrection — negative-knowledge archive

Self-Evolving Skill: If the failure taxonomy misses a mode, or a resurrection trigger type recurs, update the relevant section AND append to references/evolution-log.md. Don't defer.

Failed hypotheses are not waste. They are negative knowledge that:

1. Documents the investigation's boundaries 2. Prevents re-exploring known dead ends 3. Can come back when conditions change

This skill is the genetic-evolutionary mechanism for "don't rule out anything we have tried, as long as it can emerge through iterative process".

Why NOT just delete failed ideas

The session accumulated 17 null campaigns. Without negative-knowledge capture, we would:

• Re-explore the same dead ends in future sessions (wasted compute)
• Lose the meta-lesson each failure taught (wrong null, wrong scaling, wrong scope)
• Be unable to detect when conditions have shifted enough to retry

Failed attempts are cheaper to preserve than to re-run.

---

Failure-mode taxonomy

Each failed campaign fits one or more modes. Classification determines resurrection conditions.

Each archived file tags one or more of these.

Archive structure

plugins/crucible/skills/d-emergent-resurrection/references/
├── archive/
│   ├── <YYYY-MM-DD>-<slug>.md          Dormant/failed campaign record
│   └── ...
├── falsified/
│   └── <YYYY-MM-DD>-<slug>.md          Permanently falsified (highest bar for resurrection)
└── exhumation-log.jsonl                 Append-only: when ideas moved, why

The distinction:

• archive/ = dormant, not dead. Awaiting the right conditions.
• falsified/ = tested exhaustively under clear assumptions. Resurrection requires assumption change.

Archive file template

Use this frontmatter structure when moving a failed idea to archive:

---
id: "UNIQUE-ID"
title: "Short descriptive title"
status: "dormant"                       # or "falsified"
failure_mode: ["null-insignificant"]    # list; can be multiple
confidence: 0.95                         # how sure we are it's dead NOW
date_dormant: YYYY-MM-DD

verdict: |
  One-paragraph summary of what was tested and why it failed.

linked_ledger_entries:
  - "FINDING-ID-IN-EVOLUTION-JSONL"

linked_audits:

resurrect_if:
  - condition: "noise_floor_drops"
    trigger_metric: "trade_level_volatility"
    threshold: "< 1.2 bps (was 2.1 bps at dormancy)"
    requires: "6+ month new backtest reducing noise > 30%"

  - condition: "new_asset_regime"

    threshold: "Jaccard(newasset_patterns, eur_patterns) > 0.65"
    requires: "Trial on new asset with fold-shuffle p < 0.05"

whats_blocked:
  - "List of specific reasons it was shelved"

next_agent_checklist:
  - [ ] If noise_floor drops > 30%: re-run config on latest data
  - [ ] Do NOT assume dead — it's 'not now, but perhaps next regime'

The 3-layer exhumation process

Resurrection is deliberate. Never auto-resurrect.

Layer 1 — Autonomous flag: periodically (can be a cron job or session-start check), scan archive/* for files whose resurrect_if conditions might be currently met. Tag with CANDIDATE_FOR_RESURRECTION_<date>. This ONLY flags; it does NOT resurrect.

Layer 2 — Agent review: next research session or autonomous agent reviews tagged candidates. Picks ONE to trial (prevents thrashing). Runs 1-2 folds to check if signal has genuinely re-emerged. Either:

• Promotes to active campaign (status: "active", new audit folder)
• Updates archive file's frontmatter: "false positive at <date>, conditions looked met but retry failed"

Layer 3 — Human sign-off: before deploying anything resurrected to production (or giving it resources beyond initial re-trial), human reviews exhumation report. Confirms the condition-change is real, not a data artifact.

When to archive (triggers)

During a research session, move to archive/ when:

• A serial-gate failure killed the signal (Skill B §2, Gate C — the Irrecoverable one)
• A shuffled-null test decisively rejected (z < 1 and p > 0.9)
• 20+ parameter combos all failed → the whole approach gets archived, not each combo
• Cross-asset Gate D fails → archive the "universal" interpretation; keep asset-specific as scoped-down live version (see Skill C §3)

Archive ≠ silence. Write the file; append to exhumation-log.jsonl:

{
  "date": "YYYY-MM-DD",
  "action": "archive",
  "id": "...",
  "reason": "...",
  "from_audit": "..."
}

---

When NOT to archive

• A finding survives all gates but produces modest economics — that's live-limited-economics, not dormant; keep active and look for ensemble partners
• A finding partially fails one gate — see Skill C §3 (scope narrows, doesn't kill)
• A method used in a campaign that gave null results — the method itself isn't archived; only the specific hypothesis
• User interest waned mid-campaign — that's not a failure mode; mark as paused elsewhere

---

Population-level resurrection signals

Beyond individual-file resurrect_if, watch for population-level conditions:

• Multiple failed campaigns share a failure mode → the common cause may be addressable (e.g., all 5 used wrong null type → invent new null → resurrect all 5)
• New method/technology emerges → old failures under old methods may flip
• Asset microstructure shifts → asset-specific failures may reverse

---

Integration with the ledger

findings/evolution/evolution.jsonl entries gain a dormant_refs field:

{
  "id": "FINDING-ID",
  "status": "null",
  "dormant_refs": [
    {
      "archive_file": "plugins/crucible/skills/d-emergent-resurrection/references/archive/<slug>.md",
      "failure_mode": ["null-insignificant"],
      "resurrect_conditions": ["noise_floor_drops", "new_asset_regime"]
    }
  ]
}

Bidirectional: ledger → archive file, archive file → ledger.

Current archive (seed state)

Session ca9d7ffa-ef5a-41d0-94c8-56f113a132f2 produced:

• 17 null campaigns → each should have an archive file (SEEDING STATE: archive files not yet backfilled; do this when touching individual campaign verdicts)
• 1 positive finding (NGRAM3FU-STRADDLE-001-FULL-STACK) → remains active, NOT archived

Backfilling 17 archive entries is a future task; initial references/archive/ is intentionally empty until each campaign's verdict is reviewed and archive-written.

---

Post-Execution Reflection

After invoking this skill:

1. Did archiving a failed idea happen cleanly? If the file was too sparse or too detailed, update the template above. 2. Did resurrect_if: conditions fire (layer 1)? Were they appropriately specific, or too vague? Refine. 3. New failure mode not in the taxonomy? Add a row; log to references/evolution-log.md. 4. A previously-archived idea resurrected successfully? Document the exhumation in exhumation-log.jsonl AND note the condition pattern that worked — this is meta-knowledge.

2026-04-19 — Initial creation

Trigger: Session ca9d7ffa-ef5a-41d0-94c8-56f113a132f2. Consolidated 6 principles from findings/methodology/ + gap-analysis into this skill.

Change: Created SKILL.md with frontmatter + 6 principle sections + confirmation-count table + post-execution reflection.

Evidence: findings/evolution/audits/2026-04-19-ngram3fu-straddle/CHRONICLE.md, individual findings/methodology/*.md files.

Confirmations so far: see "Confirmation counts" table in parent SKILL.md.

Gaps to test (filled on first re-invocation):

• Does each principle's guidance hold on a DIFFERENT research hypothesis (not just NGRAM3FU-STRADDLE)?
• Are confirmation counts incremented / decremented as new evidence arrives?
