B would have replaced Alpaca historical OHLCV with the DoltHub stocks repo. It
was scoped inside a plan whose goal was killing the quota-limited free-tier APIs
— which A6 achieved without it, since Alpaca was never one of them.
Its only concrete benefit was `corporate_actions` for the KLAC-class post-filing
split (TTM EPS pre-split against a post-split price). That needs split events,
not a 4.7 GB clone, and the Alpaca SDK already in the venv exposes them. Against
that: fundamentals are 20% of the composite and P/E one of three inputs, so the
wart is small and self-correcting at the next filing; and B would have made
symbol history mutable as a routine event, which the backtest/prod parity guard
exists to catch.
The design is kept as a record, struck through rather than deleted, with the
reasoning next to it so this isn't re-derived. Also corrects the doc's status
header, the never-written migration 027 (that number went to
weighted_avg_diluted_shares), and the note that the stocks repo's license was
never reviewed.

A6 deployed cleanly and the provider keys are gone from the production `.env`,
which makes the legacy collector inert regardless of any settings row. The two
tombstones migration 029 pinned have no remaining job, and nothing in the
codebase reads either key.
Migration 030 deletes them and drops the Admin filter that hid them. Unlike
029's, its downgrade is meaningful — it restores both rows at their safe values,
since going back past this revision means going back toward code that reads them.

Three follow-ups from review of the A6 commits.
The cache-summary re-finalize raised a second durable system event on a failed
run: _runtime_finish emits for `error`/`rate_limited`, and the dedup key
includes the message, so "SEC unavailable" and "SEC unavailable · cache 511 · 2
score inputs changed" landed as two unacknowledged Admin events. Adds
`emit_event` so a re-finalize that only rewords an outcome stays silent, with a
regression test asserting exactly one event.
The rollback section still claimed disabling the SEC job freezes the cache — the
opposite of what the same page says two lines earlier, and of what the code now
does. Rewritten: there is no Admin cache-off switch, restoring `fundamental_data`
alone is temporary because the next run rebuilds it from the same snapshots and
code, and a real freeze means stopping the service.
Remaining "shadow" wording: the two import jobs have never been shadow since
activation, so `_run_shadow_import` -> `_run_source_import`, its section heading,
the deployment doc's job label, and the plan doc's "production switch remains"
handoff paragraph are all brought up to date.

The A5 cutover has been on and observed in production, so SEC Company Facts +
DoltHub earnings are already the live source for `fundamental_data`. This
removes everything the legacy path still occupied.
Gone: the three providers and their config/env keys; the weekly
`fundamental_collector` job; the cutover toggle (SEC + Dolt is now the
unconditional path, so `off` can no longer silently freeze scoring inputs); the
A5 parity report, whose deltas became structurally zero once the candidate
builder started writing the table it compared against; and the FMP tier of
universe bootstrap.
Two behavioral notes:
- Disabling **SEC Fundamentals Import** now stops the SEC network fetch only.
The local cache refresh moved outside the job-enable check, because candidates
also derive from daily closes and earnings events — freezing those on an
ingestion pause would stale scoring with no fallback left to recover from.
- `/ingestion/fetch?sources=fundamentals` still accepts the key and reports
`skipped`; there is no per-ticker fetch any more.
Migration 029 does not blanket-delete the leftover settings rows. Migrations run
before the service restart, and pre-A6 code reads an absent `job_*_enabled` row
as *enabled* — so the two behavior-bearing keys become tombstones pinned to safe
values (hidden in Admin) and only the inert three are deleted. Removing the
provider keys from the production `.env` is the matching rollout step.

The parity gate has been exercised: nine-pass investigation, fixes, two prod
reparses, and an after-report at 504/511 candidate coverage with agreement
unchanged. What remains of workstream A is the activation itself (step c, the
post-approval fundamental_data refresh — not yet implemented) and A6
decommissioning, both now specified in a handoff section with the caveats the
next implementer must carry (KLAC splits, BRK-B, FITB, the 25% guard, CIK
overrides, reparse-after-parser-changes).

1. net_debt requires BOTH cash and total_debt; a missing side is null, not
treated as zero (which would be a partial, misleading value).
2. net_debt_to_ebitda is null when TTM EBITDA <= 0 — a negative denominator
would otherwise rank a distressed issuer as favorably low-leverage.
3. The quarter tape is the CONSECUTIVE run ending at the latest period (stops at
a gap), so trend text never compares non-adjacent quarters as if consecutive.
4. YoY growth is null when the prior-year TTM is <= 0 (e.g. loss->profit), which
is not a meaningful percentage.
Also corrected the plan's net-debt formula to total debt − (cash + ST) matching
the positive-means-net-debt implementation. +4 tests. 10 passed.

1. Multi-class shares: prefer the single dei:EntityCommonStockSharesOutstanding
cover-page fact; else fall back to us-gaap:CommonStockSharesOutstanding at
period end (Alphabet has no dei fact). Never sum class facts (companyfacts is
non-dimensional) and never use weighted-average/diluted; conflicting values ->
null, counted as an "ambiguous shares outstanding" note in validation. Plan's
"sum class-specific" wording corrected. Verified live: Alphabet shares now
populate (12.1B), Apple still uses its dei cover date.
2. Fiscal context is the majority (fy, fp) among facts ending at reportDate, with
ties rejected — no longer the arbitrary first fact.
3. Hardening: catalog selectors require taxonomy == "us-gaap"; indexing drops
malformed facts (missing accession/end, non-finite value) so a custom concept
or bad date can't be selected.
Tests: +8 (dei precedence, us-gaap fallback, conflict->null, no weighted-average,
tie-context skip, foreign-taxonomy/malformed ignored, ambiguous-shares note).
14 passed, 1 skipped.

Review items 3-4 on the plan doc:
- Replace remaining "diluted shares" (the share *count*) with point-in-time
shares_outstanding (dei:EntityCommonStockSharesOutstanding) across schema,
metrics catalog and market-cap note. "diluted EPS" is left as-is (correctly a
duration fact). Adds the multi-class rule: derive the issuer-wide count from
the consolidated cover-page figure OR by summing class-specific facts (GOOG +
GOOGL) — never both, to avoid double counting.
- The framework stages into a representation *outside the live tables* (in-memory
for workstream A; a file/table handle is fine if B needs it), not physical
"staging tables" — wording now matches the implementation.

Adds the Dolt bulk-data integration hand-off plan (authored in prior
session) and applies clarifications found in a pre-handoff review:
- step (c): fields refresh from three distinct sources, not "snapshots +
close" — earnings_surprise/next_earnings_date come from earnings_events,
not SEC facts. pe_ratio = close / TTM diluted EPS and market_cap =
issuer-wide diluted shares × close stated as separate formulas.
- fundamental_snapshots made implementable: add period_start, fiscal_year,
fiscal_period; duration facts store the filing's cumulative YTD/FY values,
balance-sheet facts store period-end values. Discrete quarters, Q4, TTM
and YoY are derived at read time (correct for non-calendar fiscal years;
amendments never freeze a stale derived quarter).
- flag Q4 derivation / fiscal-period alignment as the primary A3 risk.
- anchor "tracked universe" to ticker_universe_service + per-run CIK
resolution.
All code anchors in the doc verified accurate against the current tree.
