Subject: [PATCH] feat(agentplane): EDGAR 10-K -> fiber fragment adapter
 (SP-ADAPT-TREE-001, real edition)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Moves fibered retrieval from fixtures onto REAL documents. edgar_fiber_adapter.py
fetches a company's latest 10-K from EDGAR (data.sec.gov submissions -> primary doc),
extracts its Item-level table of contents (the tree descend navigates), and emits a
Crystal Atlas fragment fiber_projection.project consumes: document root ⊑ Item sections,
registrant anchored under Item 1 to the real filing URL. No model, no datastore.

Honest scope: the Item extractor is a heuristic over filing HTML (strip tags -> match
'Item N. Title', dedup) — recovers the standard Part I-IV items, not a production parser
(exhibits/XBRL out of scope). It emits ONLY what the filing structurally states; no
ownership %s or subsidiary edges invented — cross-fiber ownership (Exhibit 21 -> GLEIF ->
E_R) is the documented follow-up. Network only in fetch; parsing is pure + offline-testable.

Proof: the committed fixture edgar_aapl_10k.fragment.json is Apple's ACTUAL latest 10-K
(17 real items, anchored to the real sec.gov URL), and the test descends its real table of
contents to 'Item 1A - Risk Factors' with the keyword navigator — no network in the suite.

Tests (+3, full suite 303 green): extract_items on a compact HTML fixture; to_fragment
anchors the registrant under Item 1; the real Apple fragment projects and descend navigates
it. Stdlib-only (urllib); live fetch exercised by the CLI.

+"""SP-ADAPT-TREE-001, real edition: turn a live SEC 10-K into a Crystal Atlas fiber fragment.
+
+Fetches a company's latest 10-K from EDGAR, extracts its Item-level table of contents (the
+document tree `descend` navigates), and emits a fragment `fiber_projection.project` consumes —
+document root ⊑ Item sections, with the registrant as an anchored entity under Item 1. This is
+what moves fibered retrieval from fixtures onto real documents; no model or datastore needed.
+
+Honesty: the Item extractor is a heuristic over the filing HTML (strip tags → match
+`Item N. Title` headings, dedup). It reliably recovers the standard Part I–IV items but is not a
+production-grade parser (messy filings, exhibits, XBRL R-files are out of scope). It emits ONLY
+what the filing structurally states — no ownership percentages or subsidiary edges are invented;
+cross-fiber ownership (Exhibit 21 → GLEIF → E_R) is the documented follow-up.
+
+Network only in the fetch path; parsing + fragment emission are pure and offline-testable.

+"""SP-ADAPT-TREE-001 (real edition): the EDGAR 10-K → fiber-fragment adapter.
+
+Offline + deterministic: the parser runs on a compact HTML fixture, and the end-to-end check
+runs on a REAL Apple 10-K fragment committed to the repo (generated once from the live filing) —
+so `descend` is proven to navigate an actual SEC filing's table of contents with no network in
+the test. The live fetch path (latest_10k / _get) is exercised by the CLI, not the suite.
