feat: start a pending lineage reconstruction (v0.87.0)

[cursor]

Buyer gap: after #125 an operator could record a Pending lineage run, then could not start reconstruction. Seed still owned the only Succeeded Demo Corp tree.

This is ADR 0013 follow-up 3 (in-process start) / ADR 0019 on the live #74 stack (3c17fd3, includes #125 and #122). Do not merge before #74. Do not land competing create rewrite #133. Do not reuse ADR 0018 / 0.86.0 (#122). Do not mix Storybook/purge (#129/#134).

• POST /api/analysis-runs/{id}/start runs ThreadWeave on the authorized cutoff bag
• Persists analysis_run_reconstruction + analysis_run_lineage_edge (3NF, immutable, two-or-more-word names)
• Home Start reconstruction on a Pending lineage detail; titled parent→child edges after Succeeded
• TEPP start is 422 — this path does not invent a theta
• A Succeeded retry returns the stored digest
• Live Event Lineage stays a separate rebuild

Verified: tests/test_analysis_run_start.py + reconstruction schema (17 passed, 1 skipped without Postgres); frontend 49 tests + oxlint. Live test_start_analysis_run_recovers_the_a100_fork self-skips without make up.

Next action: Request a lineage reconstruction, open the Pending Demo Corp row, start reconstruction, and confirm the designed A-100 fork (revised quote + delivery question under the pricing follow-up).

Stale comment

Prefer this head for the post-#125 buyer gap. POST /api/analysis-runs/{id}/start reconstructs the authorized cutoff bag through ThreadWeave, persists run-scoped edges, and rejects TEPP so this path cannot invent a theta. The A-100 fork test is the right accuracy contract.

Do not merge before #74. Do not land #133 (competing create) or #147 (same slice, wrong base main). A durable outbox/Valkey worker can follow this in-process start; do not open a third start PR.

Before merge, confirm a second click on Start while the first request is in flight cannot append a second Running event (no lease yet). After start succeeds, open the run and match the titled parent→child edges to the designed pricing-follow-up fork.

Do not merge this head. Start reconstructs a live cutoff re-query, a double-click can 500, the Result digest is persisted but not shown, and CI never calls records_from_source_posts.

Landing vehicle is #152 (8ff0fee): lock before Running, freeze analysis_source_snapshot_member at create, show the Result prefix, keep edge titles public-or-affiliated, and check the A-100 fork in CI. TEPP start stays 422.

Retarget #152 onto feat/role-responsibility-agent-ontology if it opened against main. Do not merge before #74. Do not land #133. Do not mix #129/#134.

Next action: Open #152, start reconstruction on the Pending Demo Corp row, hover the Result prefix, and confirm the designed A-100 fork.

Verdict

Do not merge. This head is dirty against the current ontology tip.

Why

Base is still ca9bd82 (pre-#148 / pre-#154 / pre-#168). The ontology branch is now 69c035b (v0.87.0 retention purge) and the requester-cutoff landing is #168 6266dc5 (v0.87.1). A Start button on a stale create/list stack will fight those clocks.

What still belongs here

• POST /api/analysis-runs/{id}/start on a Pending lineage run, ThreadWeave on the authorized cutoff bag, persist reconstruction + lineage edges, TEPP stays 422. That is still the buyer gap after Request.
• Do not invent a theta. Do not wipe live post_lineage_edge.

Next action

Rebase this slice onto #168 (or #178 if that 404 follow-up lands first). Keep TEPP at 422. Do not open a third start PR — update this head. Concurrent Start still needs no new PR for the missing lease.

Superseded by landed #170 (POST /api/analysis-runs/{id}/start, v0.88.0 / ADR 0021) on the live #74 head. Closing this v0.87.0 start slice so it is not merged in parallel.
