2026-07-26

The user wants me to generate an evolution snapshot for 2026-07-26 based on the deterministic metrics provided and the prior evolution (2026-07-21). I need to follow the skill rules strictly.

Let me analyze the metrics:

Current date: 2026-07-26

Prior evolution: 2026-07-21

Key metrics changes:

• raw_md_files: 53 (same as before? Prior showed 53 in metrics table)
• wiki_synth_manifest: tracked 1006 (vs 0 on 07-21!), done 0, pending 169, no_actions 160, skipped 677, failed 0
• wiki_total: 28 (same)
• wiki_l1: 22 (same)
• wiki_l2: 6 (same)
• type_shift_pages: 3 (same)
• twin_principle_count: 5 (same)
• discovery_reports: 9 (was 8)
• gap_reports: 8 (was 6)
• pipeline: same

So changes from 07-21 to 07-26:

1. Manifest appeared! tracked=1006 (was 0/vault missing). This is huge.

2. Discovery reports: 8→9 (+1)

3. Gap reports: 6→8 (+2)

4. Wiki pages unchanged (28, 22/6, 3 shift)

5. Twin principles unchanged (5)

6. Raw md files still 53 (symlink not followed)

I need to create the evolution snapshot with:

• Title, description, level, last_updated, tags
• Summary callout (direction)
• Tip callout (baseline note)
• At a glance table (since 3+ changes)
• Pipeline state mermaid
• Metrics table with Δ since last
• What changed grouped into: 管道与 raw, Wiki 复利层, Agent 报告与 twin
• Each change with required block (C1, C2, etc.)
• Learning strategy with tip callout

Let me identify the changes:

C1: Manifest appeared with 1006 tracked (was 0/missing)

• deterministic diff

C2: Discovery +1 (8→9), Gap +2 (6→8)

• deterministic diff

C3: Wiki stable at 28/22/6/3

• deterministic diff

C4: Twin stable at 5

• deterministic diff

C5: Raw count still 53 (symlink issue)

• deterministic diff

C6: New discovery/gap reports content

• AI Synthesis (need to check what's in the new reports)

The user provided the latest gap report (2026-07-26) but not the discovery report. I have the gap report content. The discovery report path is given: self-wiki/discovery/2026-07-26.md but content not provided. I'll need to reference it as evidence.

Also need to check prior evolution for baseline. The prior evolution is 2026-07-21.

Let me structure the output.

First, compute deltas:

• Manifest tracked: 0 → 1006 (but prior was "vault missing", now 1006 tracked)
• Manifest done: 0 → 0
• Manifest pending: 0 → 169 (prior manifest missing so no pending)
• Wiki total: 28 → 28 (0)
• Wiki L1: 22 → 22 (0)
• Wiki L2: 6 → 6 (0)
• Type/shift: 3 → 3 (0)
• Discovery: 8 → 9 (+1)
• Gap: 6 → 8 (+2)
• Twin: 5 → 5 (0)
• Raw md files: 53 → 53 (0, but still underestimated)

Now, the At a glance table should have rows for each change. I'll have 5-6 changes.

Changes:

1. Manifest appeared with 1006 tracked (pipeline)

2. Discovery +1, Gap +2 (agent)

3. Wiki stable (wiki)

4. Twin stable (twin)

5. Raw count still low due to symlink (pipeline)

6. New discovery/gap content focus (raw→agent)

• AI Synthesis

But the skill says "At a glance mandatory when 3+ changes". I'll include all.

Now, evidence chains must reference paths from the pack. The pack includes:

• Deterministic metrics (the JSON)
• Prior evolution (the markdown)
• Latest gap (the markdown)
• Discovery report path: self-wiki/discovery/2026-07-26.md
• Gap report path: self-wiki/gap/2026-07-26.md
• Wiki pages list
• Twin principle count

I need to reference these as ... or ... or ... etc. The paths in the pack are relative to self-wiki root? The metrics show "rel": "self-wiki/wiki/Communication.md" etc. So evidence chains should use those relative paths.

For the manifest, the pack doesn't give a path, but the prior evolution mentioned self-wiki/log/ no manifest. Now manifest exists with tracked=1006. I'll reference the metrics pack as evidence.

Let me write the evolution snapshot.
