fix(sec): compose total debt across the styles filers actually tag

total_debt read LongTermDebt, else LongTermDebtNoncurrent/Current, plus one of
ShortTermBorrowings/CommercialPaper. That misses two whole tagging styles, and
it feeds net_debt -> net_debt_to_ebitda -> the categorical leverage read, so the
misses were not absences but confident wrong answers: Coca-Cola scored on 0.25bn
of commercial paper against ~39bn of debt, Verizon on 21.78bn of current
maturities against ~165bn, AT&T and Exxon produced no value at all against 134bn
and 33bn tagged. Measured over 19 large caps and 14 REITs, 11 were wrong or
absent and the rest are unchanged.

Each concept's span is now respected. LongTermDebt already includes current
maturities (Apple tags all three: 71.34 + 11.01 = 82.30), so only true
short-term borrowing is added. LongTermDebtAndCapitalLeaseObligations — what KO,
HD, T, XOM and CVX tag, and nothing read before — is noncurrent and takes a
current complement, and DebtCurrent *is* that whole complement rather than an
addition to it.

The REIT branch needed disambiguating: NotesPayable is not the same line across
issuers. MAA tags NotesPayable 5.66bn = UnsecuredDebt 5.30bn + SecuredDebt
0.36bn exactly, so there it is the total and adding the secured side
double-counts; EQR tags it alongside a larger SecuredDebt, where it is only the
unsecured component. UnsecuredDebt's presence separates them.

A component alone is no longer reported as a total. Chevron tags full debt only
in its 10-K, so its 10-Q carried 0.40bn of short-term borrowing; Boston
Properties tags SecuredDebt 4.28bn against ~15bn real. net_debt needs both sides
and yields nothing when either is missing, so None costs a leverage read where
the fragment produced a confidently wrong one.

Snapshots are immutable, so this corrects new filings only; stored history needs
scripts/reparse_fundamentals.py, which cannot complete until the EQR/931182
collision is retired.

+Revision ID: 034

+Create Date: 2026-08-21 00:00:00.000000
+
+An escalated gap stops pausing setups while the issuer's own fundamentals are
+still recent (``GAP_GATE_RECENT_FILING_DAYS``). That reprieve is not permanent:
+the stored filings age out, or a newer gap appears, and the pause returns —
+silently, because ``filing_gap_aged`` only escalates gaps whose ``escalated_at``
+is NULL and so never fires twice for the same gap.
+
+``exempted_at`` is the state marker that makes the transition observable. It is
+set (quietly) while the issuer is exempt and cleared when the exemption lapses,
+which is when ``filing_gap_repaused`` fires — once per lapse, re-arming if the
+issuer's data recovers and ages out again.
+
+Nullable, and carrying no meaning of its own beyond that state: an existing gap
+starts NULL and is stamped on the next import that finds it exempt.

+# SEC fundamentals alerts, 2026-08-21
+
+Two `sec_facts` warnings, investigated against live SEC data. Both originate in SEC's
+own published data — a stale per-company Company-Facts file (1) and a stale
+ticker→CIK mapping (2) — and neither is a parser defect: no stored fundamental value
+is wrong. Every SEC-side probe below reproduces offline from public endpoints; the
+four database facts used are quoted where they appear.
+
+## 1. `filing_gap_aged` — 43 gaps, all `not_in_companyfacts`
+
+**Root cause: SEC's per-company Company-Facts files are stale for these issuers,
+while the same filings are present in SEC's own `frames` aggregation.**
+
+All ten named filings are real 10-Qs filed 2026-07-28/29, present in the issuer's
+`submissions` with `isXBRL=1`, with complete R-files and XBRL in the EDGAR archive
+— and absent from `companyfacts/CIK*.json`:
+
+| CIK | issuer | accession | filed | in `companyfacts` | newest fact in file |

+
+Ruled out, with evidence:
+
+- **Not a global SEC outage.** Company Facts is current for other issuers filing the
+  same days — MSFT `0001193125-26-323660` @2026-07-29, AAPL @2026-07-31, P&G
+  @2026-08-04, Chevron @2026-08-06, JPMorgan @2026-08-20.
+- **Not a CDN/cache artifact.** A cache-busted request with `Cache-Control: no-cache`
+  returns the identical stale 3.39 MB payload; the response carries no cache headers.
+- **Not our filter.** The scan covers every taxonomy/concept/unit in the payload.
+- **Not a metadata discriminator.** Gap and non-gap filings are identical on
+  `isXBRL`, `isInlineXBRL`, `reportDate`, `primaryDocDescription`.
+- **SEC does have the facts.** `frames/us-gaap/Assets/USD/CY2026Q2I.json` lists
+  Abbott at exactly the missing accession `0001628280-26-050134`, and Coca-Cola and
+  Ford at theirs. The per-company endpoints are the degraded ones:
+  `companyconcept/CIK0000001800/us-gaap/Assets.json` returns `"units":{"USD":{}}`.
+
+**Consequence, and why the gate changed.** Retrying `companyfacts` cannot recover
+these — Abbott's file has been stale since April. And because `active_gaps`
+supersedes a gap only on a *successfully ingested later* filing, a stale file also
+swallows Q3: the pause was open-ended, not seasonal, on 43 large caps.
+
+**Fix** (`app/services/fundamentals_quality_service.py`): once `filing_gap_aged` has
+escalated a gap (`escalated_at`), it stops pausing setups **if** the issuer's own
+newest stored 10-K/10-Q is under `GAP_GATE_RECENT_FILING_DAYS` (180) old. Pause hands
+off to the alert; an issuer with nothing that recent stays paused. `active_gaps` is
+deliberately untouched, so `_retry_backlog` keeps retrying and a recovered filing
+still resolves normally. The bound is applied to the queue path *and* the
+`validation_json` summary path, which mirrors the same filings — bounding only one
+leaves the behaviour unchanged in production.
+
+**This is a bounded reprieve, not a removal — know the two ways it ends.** Abbott's
+newest ingested filing is `0001628280-26-028357`, filed 2026-04-29, so its recency
+window closes around **2026-10-26**; most of the 43 sit on late-April filings and
+turn back to paused within days of each other. That crossing is **silent**: the
+importer escalates only gaps with `escalated_at IS NULL`, so `filing_gap_aged` does
+not re-fire for a gap it has already reported. Separately, a Q3 10-Q that also fails
+to ingest creates a *new* un-escalated gap on the same CIK, which re-pauses it at
+once (that one does raise its own `filing_gap_aged` 14 days later). Whether the
+silent re-block deserves a re-escalation signal is an open call, deliberately not
+made here — "one actionable escalation rather than a daily warning" is the existing
+design intent.
+
+**Not done, with reasons.** A `frames`-backed recovery source was considered and
+rejected: frames are calendar-aligned with a tolerance (off-fiscal filers drop out)
+and carry one fact per issuer per period, so amendment/restatement semantics differ
+from Company Facts — lossy as a snapshot source, not merely expensive. Parsing the
+filing's own inline-XBRL instance is the authoritative alternative but is a new
+subsystem (contexts, dimensions, unit refs) duplicating the parser's fact model.
+
+## 2. `snapshot_discrepancy` — 0000906107-15-000012 / -000016
+
+**Root cause: two tracked tickers claim the same filing, because SEC's
+`company_tickers.json` still points the old symbol at a non-traded co-registrant.
+No stored value is wrong and no reparse is warranted.**
+
+CIK 0000906107 is **Vivmark Residential** (VMRK, formerly Equity Residential). Both
+alerted accessions are **combined EQR + ERP Operating LP 10-Qs** — one accession, two
+registrants (0000906107 and 0000931182) — the pattern behind the existing
+co-registrant recovery path.
+
+The stored rows are **byte-identical** to what the current parser reconstructs from
+EQR's own Company Facts — every column, verified: `cik` (`0000906107`), `form`,
+`filed_date`, `accepted_at`, both period dates, `fiscal_year`/`fiscal_period`,
+`revenue`, `net_income`, `operating_income`, `diluted_eps`, `cfo`, the two nulls,
+`cash_and_st_investments`, `total_debt` (340,900,000 / null),
+`shares_outstanding`, `shares_outstanding_date`, `weighted_avg_diluted_shares`. Both
+carry `import_run_id = 6`, and CIK 0000906107 holds all 69 of its filings across runs
+6–30, so the issuer's own history is complete.
+
+Run 63 (2026-08-19) recorded
+`fields: ["cik"]` for both accessions, and the universe explains it:
+
+```
+tickers:  VMRK -> 0000906107      (Vivmark Residential, ex-Equity Residential)
+          EQR  -> 0000931182      (ERP Operating Ltd Partnership)
+```
+
+SEC's own `company_tickers.json` carries `{"cik_str": 931182, "ticker": "EQR",
+"title": "ERP OPERATING LTD PARTNERSHIP"}` — after the rename, the old symbol stayed
+attached to the **non-traded operating partnership**, the co-registrant on those
+combined 10-Qs. `resolve_ciks` reads `active_only` tickers and follows SEC, so
+0000931182 is tracked. Its Company Facts holds 7 accessions, exactly 2 of them
+EQR-prefixed, so its backfill reconstructs exactly those two rows, stamps them
+`cik=0000931182`, and collides with the rows already stored under 0000906107 —
+identical in every fact, differing only in attribution.
+
+It cannot self-heal. The collision loser never stores a row (the insert is skipped as
+immutable), so `_ciks_with_snapshots` never sees 0000931182, and it is full-history
+backfilled — refetching every submissions shard and its companyfacts — **on every
+run**, re-raising the warning each time. `fundamental_snapshots` for 0000906107 holds
+all 69 filings across runs 6–30, so the issuer's own history is complete and correct.
+
+### Fixes
+
+**Code** (`sec_fundamentals_importer.py`): a `cik`-only difference is no longer
+reported as a reconstruction discrepancy. It raises `accession_cik_collision`, naming
+both CIKs and pointing at `sec_cik_overrides`, because the fix is the universe, not
+the parser. The reparse path also excludes these from its rewrite set — rewriting a
+cik-only difference would re-stamp the filing onto the co-registrant and take it from
+the issuer that filed it. (A reparse run while both CIKs are tracked fails validation
+on `duplicate accession in staged snapshots` instead, which is a safe stop.)
+
+**Data — needs an operator, and the alert repeats daily until then.** `EQR` is a stale
+symbol: the security now trades as `VMRK`, which is already tracked at the correct
+CIK. Retiring the `EQR` ticker ends the loop. A `sec_cik_overrides` pin of
+`EQR -> 906107` would silence the collision but leave two tickers on one security,
+double-counting the issuer in scans — retirement is the right action.
+
+**Not fixed, deliberately:** the permanent-backfill loop itself. A tracked CIK whose
+only parseable filings belong to another CIK is re-backfilled every run; ending that
+in code means teaching `_ciks_with_snapshots` about foreign-owned accessions, which is
+more state for a condition that is now loudly and specifically reported.
+
+### Separate observation: `total_debt` on this issuer looks wrong
+
+Independent of the alert, and unchanged by any fix here: the parser reconstructs
+`total_debt = 340,900,000` for EQR's 2015 Q1 and `null` for Q2, while the REIT carried
+roughly $10bn of debt. `_compose_debt` returns the short-term component alone when
+every `_LONG_TERM_DEBT_AGG` concept **and** the `LongTermDebtNoncurrent`/`Current`
+pair miss — which is what happened here, and Q2 matched neither. Worth checking
+against a current REIT filer before trusting `total_debt` for that sector.
+
+---
+
+## 3. Follow-ups from the two alerts above
+
+### 3a. The reprieve in (1) ended silently — now it doesn't
+
+The hand-off in section 1 is a **bounded** reprieve. It ends two ways, and neither
+said anything: the issuer's stored filings age past `GAP_GATE_RECENT_FILING_DAYS`
+(for the 43, their last good filings are late April, so ~2026-10-26), or a newer
+filing gap arrives and the all-escalated condition fails. `filing_gap_aged` cannot
+report either, because it only escalates gaps whose `escalated_at` is NULL and so
+never fires twice for the same gap.
+
+`sec_filing_gaps.exempted_at` (migration `034`) makes the transition observable: set
+quietly while the issuer is exempt, cleared when the exemption lapses, and the clear
+is what raises `filing_gap_repaused`. Once per lapse, re-arming if the issuer's data
+recovers and ages out again. A gap that was never exempt has no transition and stays
+silent — it is simply still paused, which `filing_gap_aged` already said.
+
+The exemption rule itself is not duplicated: `fundamentals_quality_service.gap_exempt_ciks`
+is now public and the importer alerts on membership changes in exactly the set the
+gate reads.
+
+### 3b. `total_debt` was materially wrong for a third of large caps
+
+The EQR observation in section 2 was not a REIT edge case. Measured over 19 large
+caps, the old composition — `LongTermDebt`, else `LongTermDebtNoncurrent`/`Current`,
+plus one of `ShortTermBorrowings`/`CommercialPaper` — missed two whole tagging styles:
+
+| issuer | before | after | what was missed |
+|---|---:|---:|---|
+| T | None | 143.95b | `LongTermDebtAndCapitalLeaseObligations` |
+| XOM | None | 47.66b | same |
+| VZ | 21.78b | 165.23b | same (read only the current maturities) |
+| KO | 0.25b | 39.31b | same (read only commercial paper) |
+| HD | 3.50b | 48.33b | same |
+| O | 1.40b | 26.53b | REIT parts (`NotesPayable` + `SecuredDebt`) |
+| VMRK | 1.50b | 9.09b | same |
+| CVX | 0.40b | **None** | partial suppressed — see below |
+| PFE | 63.10b | 63.19b | `DebtCurrent` is the completer current side |
+| 10 others | — | unchanged | already composed correctly |
+
+`total_debt` feeds `net_debt` → `net_debt_to_ebitda` → the peer percentile and the
+categorical leverage read, so Coca-Cola at 0.25bn of debt was not a missing value —
+it was a confident *"conservative leverage"* on an issuer carrying ~39bn.
+
+The composition now spans four mutually exclusive styles, with each concept's span
+respected: `LongTermDebt` already includes current maturities (Apple tags all three
+and 71.34 + 11.01 = 82.30 confirms it), `LongTermDebtAndCapitalLeaseObligations` is
+noncurrent and needs a current complement, and `DebtCurrent` *is* that whole
+complement rather than an addition to it.
+
+**A short-term component alone is no longer reported as a total.** Chevron tags full
+debt only in its 10-K, so its 10-Q carries 0.40bn of short-term borrowing and nothing
+else. `_net_debt` needs both sides and yields nothing when either is missing, so None
+costs a leverage read where the partial value produced a confidently wrong one.
+
+The REIT branch needed disambiguating, because `NotesPayable` does not mean the same
+thing across issuers (measured over 14 REITs): MAA tags `NotesPayable` 5.66bn =
+`UnsecuredDebt` 5.30bn + `SecuredDebt` 0.36bn **exactly**, so there it is the total and
+adding the secured side double-counts — while EQR tags it alongside a *larger*
+`SecuredDebt` (5.38bn vs 6.38bn in 2013), where it is only the unsecured component.
+`UnsecuredDebt`'s presence separates the two: where tagged it is the unambiguous
+unsecured side and `NotesPayable` is ignored; where absent, `NotesPayable` is that
+side. Both sides are required, which is also what stops the branch inventing a total
+from a fragment.
+
+| REIT | before | after | |
+|---|---:|---:|---|
+| MAA | None | 5.66b | matches its own `NotesPayable` total exactly |
+| KIM | None | 8.74b | |
+| O / VMRK | 1.40b / 1.50b | 26.53b / 9.09b | |
+| BXP | 0.75b | **None** | tagged only `SecuredDebt` + paper against ~15bn real debt |
+| VTR | 0.27b | **None** | same shape |
+| 8 others | — | unchanged | already composed correctly |
+
+Known limit: where EQR tags both the parts and the aggregate, the parts sum 2.6–12.2%
+*below* it, so this branch approximates. It is last in line — any issuer tagging an
+aggregate never reaches it — and the alternative there is no value at all.
+
+### Sequencing the history fix
+
+Snapshots are immutable, so **3b corrects new filings only**; every stored quarter
+keeps its old `total_debt`. `scripts/reparse_fundamentals.py` exists for exactly this
+("after a parser fix, keeping the stored row is preserving a stale cache").
+
+**Retire the `EQR` ticker before reparsing.** A reparse backfills every tracked CIK,
+so while both 0000906107 and 0000931182 are tracked, both stage the same two 2015
+accessions and the run fails validation on `duplicate accession in staged snapshots`.
+That is a safe stop — nothing is written — but the reparse will not complete until the
+collision is gone.
