feat(sec): SPAC de-SPAC lifecycle — 8-K milestones, merger-proxy & redemption extraction by sroussey · Pull Request #166 · workglow-dev/sec

sroussey · 2026-06-24T05:01:36Z

Summary

Builds out the SPAC de-SPAC lifecycle on top of the consolidated spac report, in three increments that all land here (none were previously on main):

§4a — 8-K milestone dates. Deterministically map 8-K item codes for known SPACs to lifecycle events (1.01 → definitive_agreement, 1.02 → terminated, 2.01 → completed, 5.07 → vote), grouped into spac_deal attempts via the event stream (idempotent replays, stable deal_index).
§4b / §4b.1 — merger-proxy extraction. AI-extract target/PIPE/consideration from the 14A/14C merger & revised-proxy family (DEFM14A/PREM14A, DEFM14C/PREM14C, DEFR14A/PRER14A) into spac_merger_extraction, correlated onto the matching deal; definitive statements emit the proxy milestone. Per-extractor confidence floor (SEC_MERGER_PROXY_CONFIDENCE_FLOOR).
§4c — redemption actuals. AI-extract realized share redemptions from a known SPAC's post-vote 8-K narrative and roll them up into total_redemption_amount.

§4c detail (this session's work)

When a known SPAC files an 8-K carrying item 5.07/2.01/8.01, ingestion escalates the fetch to the full submission .txt (the existing S-1/DRS mechanism), reads the primary document + EX-99.x exhibits, and processRedemption8K AI-extracts realized redemptions into a per-accession spac_redemption_extraction row. deriveDeals correlates redemption_amount / redemption_shares onto the matching spac_deal using an announcement-based window (upper bound = the next deal's announcement, ignoring outcome_date, so a redemption reported at/after closing still attaches). The deal column is the sole source sumRedemptions totals, so each redemption is counted exactly once (no event is emitted). New redemption extractor id (own version slot + dead-letters), SEC_REDEMPTION_MODEL / SEC_REDEMPTION_CONFIDENCE_FLOOR config, and a sec spac backfill-redemptions command that sweeps historical known-SPAC trigger 8-Ks off the bootstrapped filing metadata.

Design specs & the §4c implementation plan live in the PRD repo under docs/superpowers/specs/ and .../plans/.

Test Plan

bun test src/sec/forms/miscellaneous-filings/ src/sec/forms/registration-statements/s1/ src/storage/spac/ src/storage/versioning/ src/task/spac/ src/task/forms/ → 266 pass, 0 fail
bunx tsc --noEmit → clean
No-double-count invariant proven by an idempotency e2e test (reprocessing the same 8-K keeps total_redemption_amount single)
Gating verified SPAC-only with defense-in-depth (task escalation + processForm8K re-gate + processRedemption8K trigger/SPAC/deal checks)
Reviewer: spot-check a real SPAC's redemption 8-K end-to-end via sec fetch form <cik> 8-K and sec spac report <cik>

Note: this PR carries all three SPAC increments (§4a/§4b/§4c) because none were yet on main. The pre-existing FetchQuarterlyIndexTask / FetchDailyIndexTask network-timeout test failures are unrelated to this work.

Skip the milestone path when neither period-of-report nor filing_date is available, so an undated 8-K can't write junk dates onto the deal/row. Adds a regression test.

The `sec version CLI` status test's expected extractor list was missing `merger-proxy` and `redemption`, so `db setup` (which bootstraps all extractor ids) produced more rows than asserted. This test lives outside the feature dirs the local runs covered, so CI surfaced it. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01X3vG1nXpbisZQuoduW7Z1f

- deriveDeals: first deal's redemption window is unbounded below, so a vote-results 8-K filed before a completion-only deal's date still attaches (was dropped → total_redemption_amount under-counted). - processRedemption8K: parse/render of filer HTML is wrapped so a malformed body dead-letters the section instead of aborting the filing (restores the "extraction degrades, never aborts" invariant; mirrors the merger-proxy path). - BackfillRedemptionsTask: isolate per-filing failures so one bad 8-K doesn't abort the historical sweep. - redemption schema: minimum:0 on redemption_amount / price_per_share so a negative/sign-error value dead-letters rather than corrupting the rollup. - extractRedemption: drop a figure-less response (null shares AND null amount) so the no-redemption case doesn't persist a meaningless row. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01X3vG1nXpbisZQuoduW7Z1f

recomputeAndSaveDeals upserted derived deals but never deleted rows from a prior, larger derivation. When the derived deal set shrinks (event stream or derivation logic changes), orphaned spac_deal rows survived and their stale columns — notably redemption_amount — were still summed by sumRedemptions, over-counting total_redemption_amount. Now delete any existing deal whose deal_index is absent from the recomputed set before saving. Shared by the 8-K milestone, merger-proxy, and redemption writers. Adds SpacRepo.deleteDeal.

- parseEightKSubmission.test.ts: use bun:test (repo convention; was the only file importing vitest). - sectionRunner parseConfidenceFloor: correct the JSDoc — a 0 floor admits every row (disables the floor); NaN is the drop-everything case. - BackfillRedemptionsTask: query filings by (form, cik) to use the ["form","cik"] index instead of loading all of a SPAC's filings and filtering. - CLAUDE.md: the milestone grouping function is deriveDeals, not the stale deriveDealsFromEvents reference.

Resolves conflicts created by PR #166 (SPAC de-SPAC lifecycle / merger-proxy / redemption extraction) landing on main after this PR opened. Conflicts resolved: - src/sec/forms/miscellaneous-filings/Form_8_K.storage.ts - Function signature combines both side's additive params: extractor_id, extractor_version (this PR), fullSubmissionText, model (#166). - Event writes go through replaceEvents() (this PR), threading extractor_id + extractor_version into the version-scoped delete-then-insert. - SPAC milestone mapping + redemption extraction blocks from #166 follow unchanged after the events are persisted. - src/task/forms/ProcessAccessionDocFormTask.ts - Keep TypeAccessionNumber import (this PR), processMergerProxy + hasRedemptionTriggerItem imports (#166). - 8-K dispatch call site passes both extractor_id/extractor_version and fullSubmissionText into processForm8K; merger-proxy case from #166 follows. - src/sec/forms/registration-statements/s1/sectionExtractors.ts (auto-merged cleanly by git but the new extractMergerDeal / extractRedemption functions still called the pre-PR wrapUntrusted shape + UNTRUSTED_PREAMBLE constant, which this PR removed. Both updated to the nonce-fence API (wrapUntrusted -> { wrapped, nonce }, buildUntrustedPreamble(nonce)) so the new SPAC AI extractors get the per-call nonce fence + multi-stage defang for free. Without this, the prompts would interpolate as "[object Object]" and the model receives garbage. Verification: - targeted: bun test src/sec/forms/miscellaneous-filings/ \ src/sec/forms/proxies-information-statements/ src/task/forms/ \ src/storage/spac/ src/storage/form-8k-event/ \ src/sec/forms/registration-statements/ -> 229 pass / 0 fail. - full: bun test -> 1410 pass / 7 fail. All 7 fails are pre-existing FetchDailyIndexTask + FetchQuarterlyIndexTask 5000ms network timeouts unrelated to this PR (sandbox can't reach SEC.gov reliably). - bun run build -> clean (bun build + tsc, no errors). Co-Authored-By: Claude <noreply@anthropic.com>

…e-fence API The new SPAC extractors added in PR #166 (extractMergerDeal, extractRedemption) called the pre-PR wrapUntrusted shape (returning a string) and the removed UNTRUSTED_PREAMBLE constant. After this PR swapped wrapUntrusted to return { wrapped, nonce } and replaced the constant with buildUntrustedPreamble(nonce), the surviving call sites template-interpolated UNTRUSTED_PREAMBLE as a free identifier -> compile error (TS2552), and even if the type had survived the { wrapped, nonce } object would have rendered as "[object Object]" in the prompt -> the model receives garbage and silently returns nothing (caught by Form_DEFM14A.storage.e2e.test.ts target_name=null assertions in the post-merge run). Both extractors now use the same nonce-fence + multi-stage defang as the other section extractors -- a forced consequence of the merge, extending the per-call nonce + entity decode + NFKC + zero-width strip protection to the new SPAC AI extractors at no extra design cost.
