23+| ID | Textbook | Status | Branch B Reference | Branch A Observed | Reason |
24+| --- | --- | --- | --- | --- | --- |
25+| A01 | 小学语文一上 | PASS | Branch B stage report: PASS; 126 nodes, 166 flows on 小学语文一上 pipeline. | phi=40, mu=13, J=35, mode=degraded | Pipeline ran on the required real-data slice and produced non-empty phi/mu/J state. |
26+| A02 | 小学数学一上 | PASS | Branch B stage report: PASS; 58 nodes, has_cn=True on 小学数学一上 mixed text. | phi=15, mu=7, J=18, mode=minimal | Chinese-bearing nodes exist on the mixed textbook slice; digit-bearing nodes are reported separately. |
27+| A03 | 初中语文七上 | PASS | Branch B stage report: PASS; 276 nodes, 20 sedimentation traces on 初中语文七上. | phi=36, mu=6, J=28, mode=minimal | Sedimentation and experience-region observables are present on the required real-data slice. |
28+| A04 | 初中数学七上 | STRUCTURAL MISMATCH | Branch B stage report: PASS; 294 edges, asymmetry ratio 1.00 on 初中数学七上. | phi=35, J=32, flow-asym-proxy=0.7721 | The scenario ran, but the primary Branch B asymmetry-ratio metric does not map cleanly onto Branch A. |
29+| A05 | 高中语文必修上 | PASS | Branch B stage report: PASS; 397 nodes, phi range [-0.13, 0.15] on 高中语文必修上. | phi=55, mu=13, J=53, mode=degraded | Long-text run stayed finite and showed no obvious overflow/divergence symptom. |
30+| A06 | 小学语文一上, 小学数学一上 | PASS | Branch B stage report: PASS; 8 new nodes after 语文→数学 subject switch. | phi=17, mu=6, J=9, mode=degraded | Active region changes under subject switch while some earlier structures remain alive. |
31+| A07 | 初中语文七上 | PASS | Branch B stage report: PASS; 182/189 phi entries preserved after reset. | phi=46, mu=0, J=41, mode=minimal | reset_session() clears session activation while preserving long-term graph/potential structure. |
32+| A08 | 小学语文一上 | FAIL | Branch B stage report: PASS; confidence 0.333→0.889→0.381 after positive/negative feedback. | mode=minimal, emit=minimal: idle, active=0 | emit() returned no activated output target on the required slice, so the positive/negative feedback loop could not be meaningfully exercised. |
33+| A09 | 小学语文一上 | PASS | Branch B stage report: PASS; sedimentation gradient (20,4)→(20,10). | phi=15, mu=3, J=11, mode=minimal | Repeated rounds show incremental stage progression, even though several observable lists are capped. |
34+| A10 | 初中数学七上 | PASS | Branch B stage report: PASS; 16 snapshot fields present on real textbook state. | phi=32, mu=10, J=47, mode=degraded | All Branch A locked snapshot fields are present on real textbook-driven state. |
35+
36+## Explicit Structural Mismatch
37+- `A04`: Branch B's A04 metric is based on forward/backward graph edge weights. Branch A only exposes directed J flow, not a directly comparable directed graph-edge surface, so a fair asymmetry-ratio comparison is a structural mismatch.
38+- `A01/A08`: Branch A emit() returns a plain string, not Branch B's structured payload with activated nodes and active_count.
39+- `A05/A10`: Branch A does not expose attention used/total. free_capacity is the locked comparable field instead.
40+- `A08/A10`: Branch A commit_feedback() is queued and becomes observable on the next step, unlike Branch B's more immediate feedback probes.
41+
42+## Concise Fairness Interpretation
43+- This run materially reduces the main A/B fairness gap because Branch A was executed on the same dataset, same file set, and same A01-A10 slice family as Branch B.
44+- It does not erase Branch A's current disadvantages: A08 fails on the mandated slice, A04 is not directly comparable, and most Branch A state sizes remain much smaller than Branch B's reference values.
45+
46+## Does This Reduce The Main A/B Fairness Gap?
47+- Yes. The earlier fairness concern was unmatched real-data coverage. That concern is now materially reduced because Branch A was run on the same real textbooks and scenario family.
48+
49+## Recommendation
50+- Decision: `enough to proceed with merge decision`
51+- Reason: The main A/B fairness gap was the unmatched real-data harness. This validation closes that gap enough to make a merge decision on current evidence. The remaining issues are explicit Branch A results: one failed scenario (A08) and one true structural mismatch (A04), not hidden harness differences.

2+# Review: Branch A Real Textbook Validation
3+
4+## What Was Run
5+- Branch A base commit `419ae8d39150806011c1eb6082c7fc8c6a337735` on branch `review/branch-a-real-textbook-validation`.
6+- Branch B reference commit `c7342881bb2ebfa5e7f927c91a7806416288573b` for dataset/scenario parity.
7+- Same dataset directory: `/Users/george/code/china-text-book-md` with the exact 5 textbook files required by Branch B.
8+- Same real-data scenario family: A01-A10.
9+
10+## Outcome
11+- Succeeded: A01, A02, A03, A05, A06, A07, A09, A10
12+- Failed: A08
13+- Structurally not comparable: A04
14+
15+## Decision Readout
16+- The matched real-textbook run materially reduces the earlier fairness gap.
17+- It does not materially change a conclusion that Branch B currently has broader and cleaner real-data validation coverage.
18+- Recommendation: `enough to proceed with merge decision`
19+- Rationale: The main A/B fairness gap was the unmatched real-data harness. This validation closes that gap enough to make a merge decision on current evidence. The remaining issues are explicit Branch A results: one failed scenario (A08) and one true structural mismatch (A04), not hidden harness differences.
