xref-label-update

description

Update cross-reference (XREF) labels in ENSDF adopted files when experimental datasets are added or removed. Handles systematic label shifting, new label insertion, deleted label removal, and preserves parenthetical notations such as (energy), (*), and (?). Covers both add-dataset and remove-dataset scenarios with 5%+ spot-check validation. Skip column_calibrate and line ruler; pad XREF lines to 80 characters only.

Update ENSDF Cross-Reference (XREF) Labels

Task Overview

Update cross-reference labels in ENSDF adopted file when experimental datasets are added or removed, causing existing dataset labels to shift.

Scenario 1: Add Dataset

Input

1. File: [path/to/adopted.ens]
2. New dataset: [X] = [description]
3. Mapping: e.g., assume [X]=F: F→G, G→H, H→I, I→J, J→K (A-E unchanged)

Steps

1. Update X-Records

Insert new dataset at appropriate position, shift subsequent labels, pad spaces to 80 characters.

2. Alphabetically Shift Existing XREF Labels

Apply mapping — notations (energy), (asterisk), (question mark), (energy asterisk), (energy question) shift naturally with labels:

• XREF=F → XREF=G
• XREF=BFGH → XREF=BGHI
• XREF=BFG(2103)HIJ → XREF=BGH(2103)IJK
• XREF=F(*)J → XREF=G(*)K
• XREF=H(7300*)J → XREF=I(7300*)K

3. Insert New XREF Label

For levels in new dataset, insert label alphabetically (no (notations) needed):

• XREF=ABCDGHIJK → XREF=ABCDFGHIJK
• XREF=BGH(2103)IJK → XREF=BFGH(2103)IJK

Omit column calibrate and line ruler checks. Only pad XREF line to 80 characters with spaces.

4. Spot-Check

Verify randomly-selected 5%+ of XREF entries (at least 5):

• Check shift mapping applied correctly
• Verify new label inserted where needed
• Confirm alphabetical order
• Ensure all lines exactly 80 characters

Example

New: XF = 9BE(37CA,34ARG)
Mapping: F→G, G→H, H→I, I→J, J→K (A-E unchanged)

Shift:
XREF=ABDFG(2103)HIJ → XREF=ABDGH(2103)IJK

Insert F for levels also existing in F dataset:
XREF=ABDGH(2103)IJK → XREF=ABDFGH(2103)IJK

Scenario 2: Remove Dataset

Input

1. File: [path/to/adopted.ens]
2. Removed dataset: [X] = [description]
3. Mapping: e.g., removed B: C→B, D→C, E→D, F→E, G→F, etc. (A unchanged)

Steps

1. Update X-Records

Remove dataset line, shift subsequent labels up, pad spaces to 80 characters.

2. Shift XREF Labels

Apply shift mapping to each label present. Delete removed label (B) if present.

Examples:

• XREF=ABC → XREF=AB (had B, removed B, C→B)
• XREF=ACD → XREF=ABC (no B, just shift C→B, D→C)
• XREF=C → XREF=B (shift C→B)
• XREF=ACDEFGH → XREF=ABCDEFG (no B, shift all)
• XREF=ACDEF(2420)GIK → XREF=ABCDE(2420)FHJ (notations shift with labels)
• XREF=FG(7520*) → XREF=EF(7520*) (notations preserved)

3. Validation

Omit column calibrate and line ruler checks. Only pad XREF line to 80 characters with spaces.

CRITICAL: This task ONLY updates XREF labels. Do NOT delete any data records (L-records, G-records, comment lines). Human evaluators handle data removal separately.

4. Spot-Check

Verify randomly-selected 5%+ of XREF entries (at least 5):

• Check shift mapping applied correctly
• Verify removed label deleted where present
• Confirm alphabetical order
• Ensure all lines exactly 80 characters

Example

Removed: XB = 36SI B-N DECAY (503 MS)
Mapping: C→B, D→C, E→D, F→E, G→F, H→G, I→H, J→I, K→J, L→K (A unchanged)

Original XREF:
XREF=ABCDE → XREF=ABDE (B removed, D→C, E→D)
XREF=ADEFG(2420)HIJ → XREF=ACDEF(2420)GHI (no B, shift down)

Success Criteria (Both Scenarios)

• ✅ X-records updated (inserted/removed + shifted)
• ✅ XREF labels shifted per mapping
• ✅ New label inserted OR removed label deleted
• ✅ All lines 80 characters
• ✅ Spot-check passes (5%+ samples, minimum 5)
