 **Recommendation:** One paired PENDING-62 (the PENDING-61 pattern), each FIX separately checkable; split to 62/63 only if steward prefers. **Verified: neither FIX touches the v2.1.0 spec** (zero occurrences of the seam/collision language — no re-supersession) nor any LOCKED field's meaning/shape.

+## PENDING-63 — Gate zero's pending→archive seam is structurally closed at --apply (PENDING-52 lineage) + the shared-source archive design for compound sources
+**Date:** 2026-07-18
+**Tag:** [HARDENING] — class-level defect in the ruled PENDING-52 mechanism + the compound-source case its invariant lacks. Jurist-docketed 2026-07-18 ("gate-zero territory — PENDING-52's lineage, not PENDING-58's"; ruling: `chamber-library/docs/2b-first-vdsl-exercise-JURIST-RULING-2026-07-18.md`).
+**Summary:** Two findings from the first V-DSL exercise, meeting at the same layer. **(1) The seam:** `graduate_to_canonical.source_gate` hands `archive_sources.add_single` a source staged in `pending-graduation/` — which sits INSIDE the archive root `DEST` — and `copy_or_rezip` refuses any source whose path contains `DEST` ("source already in archive") → rc 1 → the candidate is refused. **Every pending-staged graduation fails its apply leg, on every tier.** **(2) The compound-source case:** the archive model is one-slug-one-copy (`DEST/{slug}.ext`); the Loeb DSL is one 533 MB artifact carrying 952 works — per-slug copying would make 952 independently-hashable copies of a single artifact, the multiple-homes condition the ratified hash-locality principle forbids (jurist: rule it on integrity grounds, storage is a side effect; the property to preserve is *many works reference ONE archived artifact with ONE hash*).
+**Rationale:** **Substrate-verified 2026-07-18: no graduation has EVER completed through the pending-staging path** — 0 of 324 archive-manifest entries carry a `source_origin` inside `pending-graduation/`; the only two manual-archive entries (Olson 2026-07-06, Handke 2026-07-09) were archived directly from Desktop paths via `--add`; the 14 legacy pending entries carry no `canonical_slug`. **PENDING-52's mechanism is ratified-and-never-exercised; the seam is latent since birth, not a regression.** Third instance of the class (after the `--no-verify` grep and the ABSTAIN split): negative/indirect evidence standing in for a positive property until something exercised it.
+**Options:** **(a)** one design pass fixing both at the same layer (RECOMMEND, jurist-endorsed "sensible — they meet at the same layer"): a compound/shared-source archive form (one archived artifact, one hash, N per-work manifest entries referencing it) whose archive step also repairs the pending→DEST move (move-or-copy out of staging into the archive proper, containment check retained for true re-archive attempts); positive-test the seam end-to-end as part of landing (the class's own lesson). **(b)** fix the seam alone first (unblocks non-Loeb pending-staged graduations; compound-source separately). **(c)** hold both until Region-4 forces them (REJECT — the seam bites every tier's pending-staged apply, not just Loeb).
+**Recommendation:** (a). Design brief FOR-JURIST before code (gate-zero territory; the enforced precondition's `enforced_by` text in `graduation-spec.yaml` may need a matching FIX).
+**Files affected (on authorization):** `scripts/archive_sources.py` (the shared-source entry form + the pending→archive move) · `scripts/graduate_to_canonical.py` (source_gate apply leg, if the call shape changes) · `_curation/graduation-spec.yaml` `preconditions:` (enforced_by wording, if changed) · `scripts/test_tools.py` (the end-to-end positive test) · Chamber Sources `manifest.json`/`pending-manifest.json` entry shapes.
