IB-WP-0016: refresh validation baseline after T01/T02 smoke run

Run a fixture-backed end-to-end smoke against the real Lefevre EPUB
(max-chunks 3) and capture the result in the validation note and the
workplan. The pipeline produces a complete infospace with stable
chapter-01-part-NNN source IDs, full chapter/book/anchor provenance on
every source artifact, viable metrics, and exact-title entity dedupe.

Refresh the workplan validation baseline to reflect the post-T01/T02
state, and add a remaining-gaps section that maps the open issues to the
right follow-on tasks: cost/scope controls and plan preview to T03, the
trading-literature profile to T04, chunk-level resume to T06, and a
richer generation-summary report (entity titles, chapter coverage,
anchor links) to T07.

-Current WP-0015 infrastructure can initialize the local EPUB and run
-source-only metrics in a disposable workspace:
+After T01 and T02, the local Lefevre EPUB is intake-ready:
 
-- source chunks: 155
-- entity count: 0
-- relation count: 0
-- evaluation count: 0
-- source-only metrics history can be written without provider calls
+- 67 body chunks at default `max_words=800`, all 24 roman-numeral chapters
+  detected, stable IDs `chapter-01..chapter-24` with `-part-NNN` suffix
+- Cover, PG header/footer, Contents, Transcriber's Notes, and license
+  sections classified out of the body stream by default
+- Per-chunk provenance carries full OPF book metadata, chapter label and

+### Smoke Run (2026-05-17)
 
-- most generated chunk titles collapse to the same Gutenberg page title
-- EPUB spine/chapter metadata is not yet honored deeply enough
-- archive-order sorting risks confusing reading order
-- non-body sections such as cover/header/footer/license need explicit policy
-- plan output is too prompt-heavy for cost review on a 155-chunk book
-- long-book resume needs chunk-level state, not only whole-run skip
-- generated entities need cross-chunk dedupe/merge policy
+A fixture-backed end-to-end smoke run with `--max-chunks 3` against the
+real EPUB produced a complete infospace:
+
+- 3 source chunks (`chapter-01-part-001..003`), 3 entities, 3 relations,
+  3 evaluations, 1 generation-summary report
+- All chapter/book/anchor provenance fields land in `artifacts/index.yaml`
+  (verified: `chapter_label=I`, `chapter_number=1`,
+  `page_anchors=[Page_1, Page_2, Page_3]` on the first chunk)
+- Metrics viable: `coverage=1.0`, `redundancy=0.0`,
+  `granularity_entropy=1.79`, viability gates pass
+- Same-title entities returned by repeated stages were upserted to single
+  artifact files — basic dedupe works for exact-title matches
+
+### Remaining Gaps
+
+These are the gaps a serious full-book run still hits:
+
+- No compact `plan` output for cost/call preview on a 67-chunk run
+  (~5 stages per chunk = ~335 provider calls at default `max_words`) — T03
+- No `--chapter`, `--from-chapter`, `--to-chapter`, `--cost-cap`, or
+  `--max-calls` selection — T03
+- Generic profile produces sensible structure but does not push concepts
+  toward traders, markets, lessons, or strategies — T04
+- The generation-summary report only shows counts and metrics; it should
+  surface entity titles, chapter coverage, page-anchor links, and unmapped
+  chunks for human review — T07
+- Long-book resume is still whole-run-skip, not chunk-level — T06
+- Near-duplicate entities across chunks (e.g. "Larry Livingston" vs "the
+  narrator") need cross-chunk merge/dedupe policy before a 24-chapter run
