# JCL-TRACE-000 · scratchpad handoff

> Captain redirected: this fire is being absorbed into TRACEROUTE-TEMP-000's parallel test instantiation. Exiting clean. The Phase 0 self-prompt + the research scaffolded below are TEMP-000's to use or supersede.

## What exists upstream of this file

1. **Phase 0 self-prompt (working draft, do NOT need to re-ratify)** — `_ops/coord/JCL-TRACE/JCL-TRACE-000-A000-05-24-05-59-self-prompt.md`. Contains: subject-scope boundary (1865–1968 + tagged afterlives), category swap proposal, predicted central nodes, failure-mode mitigations, template usage call.
2. **TRACE-000 substrate read** — `_TRACE-000/views/traceroute.html` + `_TRACE-000/data/traceroute-nodes.json` + `_TRACE-000/LAUNCH-TRACE-000.command`. These are the closer-fit precedent than LOTR (`adotom-1.1` is axis-heavy; `trace-000-1.0` is categorical and is the right base).

## Schema mutation proposal for TEMP-000 (carry forward)

From the JCL Phase 0 §7 template call:

- **Swap `scale` → `category`** with values `upstream | core | downstream | lateral`. The four-cardinal-direction shape works for any subject with a central node (legal regime, person, event, institution).
- **Add `era_bucket`** as optional string for timeline grouping. JCL example values: `antebellum | reconstruction | regime | civil-rights | afterlife`. Other subjects pick their own buckets.
- **Keep `contested` tag** — load-bearing for any subject where peer scholarship splits.
- **Add tag-class `enforced-extralegally-by`** — emerged as load-bearing for legal-historical subjects with off-page enforcement (lynching, sundown towns, convict leasing as a node-class, not just kin links).
- **Timeline lane span: parameterize.** TRACE-000 hard-codes 365-day window. TEMP-000 needs `time_window: { start, end, tick_unit }` so subjects spanning 1830-2026 (JCL) or longer/shorter periods work cleanly.

## Verified URLs (web-searched, this session)

These were verified via WebSearch during the brief research pass before the stop directive:

- **Ida B. Wells, *Southern Horrors: Lynch Law in All Its Phases* (1892)** — full text:

- **Fair Housing Act 1968** — direct archives.gov milestone landing page not surfaced by site-filtered search; TEMP-000 should verify before citing. Fallback: FBI Classification 177 page at https://www.archives.gov/research/investigations/fbi/classifications/177-housing-discrimination.html confirms FBI fair-housing enforcement context. HUD's own enforcement portal also valid backup.

## Kin verb catalogue candidates (emerged during planning)

These should remain emergent, not pre-locked, but the corpus pressure already surfaced:

- `derives-from` (slave codes → black codes)
- `codifies` (segregation statutes ← Plessy)
- `enables` (13A exception ← convict leasing) — note the inversion: the *enabler* is the loophole
- `judicially-narrows` (Slaughter-House → 14A P&I clause)
- `judicially-permits` (Civil Rights Cases → private discrimination)
- `evades` (disenfranchisement-mechanics → 15A)
- `enforced-extralegally-by` (regime → lynching, sundown towns)
- `responds-to` (Great Migration → regime)
- `documents` (Wells → lynching)
- `overturned-by` (Plessy → Brown)
- `dismantled-by` (regime → CRA/VRA/FHA)
- `succeeded-by` / `mutated-into` (regime → mass incarceration framing) — `contested`
- `modeled-on` (Nuremberg → US racial law) — per Whitman
- `comparable-to` (regime ↔ apartheid)
- `weakened` (Shelby → VRA §4(b))

## Falsification candidates (for honest-narrative discipline)

- **Was Reconstruction "ended" in 1877?** Federal occupation had been receding for years; the Compromise codified what was underway. Surface as nuance, not crisp end-date.
- **Did Plessy "create" segregation?** Many segregation statutes predate Plessy 1896 (TN railroad 1881, e.g.). Plessy *ratified* an existing pattern; framing it as origin is narrative-arc bias.
- **Did the regime "end" in 1965?** Contested. Alexander argues conversion, not termination. Shelby 2013 suggests partial reversal. Surface as open, do not adjudicate.

## Constraints carried forward (TEMP-000 must honor)

- **No fabrication** — every node URL verified or flagged as needing TEMP-000 verification.
- **No partisan flattening** — `contested` tag for interpretive splits, no adjudication in the corpus.
- **Honor the dead** — lynching counts from Tuskegee/EJI as record, not flourish. The numbers are real people.
- **Filename hygiene** — `[a-zA-Z0-9_.-]` only.
- **AXM stamps** on every artifact TEMP-000 produces.
- **AXM-LAUNCH-001** — viewer-bearing project ships a `LAUNCH-<CODE>.command` at root.

## Operational note to TEMP-000

If the JCL subject is being used as TEMP-000's first real-world test instantiation, the Phase 0 self-prompt's §7 (template usage call) was the meta-finding I would have surfaced at Phase 6. Carry it forward:

> TRACE-000 (`trace-000-1.0`) is closer-fit base than LOTR (`adotom-1.1`). For a legal-historical subject, swap `scale` → `category`, add `era_bucket`, add tag-class extensibility, parameterize the timeline window. These should be TEMP-000's first locked design moves.

## Exit

No viewer built. No launcher built. No ship report. Phase 0 working draft + this scratchpad are the entire JCL-TRACE-000 footprint. TEMP-000 owns the build from here.

Deviation count at exit: `0`.
