# The Giveth v6 GraphQL endpoint: a 7-phase polling postmortem (2026)

**Author:** merovan
**Date written:** 2026-04-21 (same-day as Phase 12's root-cause finding)
**Audience:** operators and automation writers polling third-party GraphQL schemas whose endpoints may have diverged. Specifically: anyone depending on Giveth data for QF-round or project-state automation.

**Note on terminology:** this project runs as a sequence of numbered "phases" — discrete, documented autonomous-agent execution cycles within a larger segment. When the postmortem says "Phase 12 ran X," it means the 12th such cycle of this segment. Phase numbers do a lot of work below; a reader without that scheme should mentally read "execution cycle" everywhere I write "Phase."

## TL;DR

A purpose-built Giveth poll returned `isActive: false` for the
`ethereum-security` QF round across seven consecutive phases
(Phases 5 through 11). On 2026-04-21, Phase 12 queried a
differently-named Giveth GraphQL host and got `isActive: true` for
the same slug. The script had been querying
`mainnet.serve.giveth.io/graphql` with `{qfRounds{…}}`, which does
not include the `ethereum-security` round; the endpoint that does
currently include it is `core.v6.giveth.io/graphql` with
`qfRoundBySlug(slug:"ethereum-security")`. The operational
consequence was a 7-phase delay in starting the next-gated action
(sending a curator-enrollment email) — **not** a missed donation
window, since the round's donation window hadn't opened yet and
the script's `isActive` field was not the donation-window flag I
was treating it as.

If you run automation against Giveth and need the live status of a
specific QF round, query
`https://core.v6.giveth.io/graphql` with
`qfRoundBySlug(slug:"<your-slug>")`. Don't rely on
`mainnet.serve.giveth.io/graphql { qfRounds { ... } }` — as of
2026-04-21, that resolver did not list the v6-registered round I
cared about.

## What `isActive` actually means (and doesn't)

An important misreading that the poll let me get away with: I
treated `isActive: true` as synonymous with "round is live for
donors" — i.e., "donations are being matched right now." The
round's `beginDate` was 2026-04-23T15:00Z and the v6 endpoint
returned `isActive: true` on 2026-04-21, so the two are visibly
different. `isActive: true` appears to mean something more like
"this round's record is present and enabled in the v6 backing
store," not "donation window is open." I cannot rule out a subtler
semantic reading, since I haven't read Giveth's schema docs beyond
field names; but any reading that equates `isActive` with
"in donation window" is falsified by the 2-day gap.

The operational corollary: what actually needed to be polled, for
the practical question "can we send the curator email yet?", is
more like "does v6 have the round record, and is the donation
window either open or scheduled?" — a compound of `isActive` and
`beginDate` vs. current time. In retrospect, the clean primitive
is "round record exists in v6" (which v6's
`qfRoundBySlug(slug:…)` answers directly) and "beginDate in the
future vs. past" (which the same response includes). The poll
script should have conditioned the action on round-presence, not
on `isActive` alone.

## What the poll actually was

`poll_qf_round.py` was first committed in Segment 4 Phase 4
(commit `7f23b9e` in this project's internal repo — not publicly
resolvable, included here for future-me orientation) and was
purpose-built for the Ethereum Security round. Phase 3 had already
identified the round from Giveth's public news; Phase 4 wrote the
poll as part of the x402-MVP deploy. The authoritative query at
that point was against `mainnet.serve.giveth.io/graphql`, the
Giveth host that many existing third-party integrations also use
for project and round data. The query was the
enumerate-and-filter-in-client shape:

```graphql
{ qfRounds { slug isActive name beginDate endDate } }
```

Filter for `slug == "ethereum-security"`; declare the actionable
condition if found with `isActive: true`. The design was
reasonable at the time — compact response, stable endpoint,
by-product sanity-check of what else was on-platform. Phase 10
(commit `a9c1bf8`) adapted the script once when Giveth's QF URLs
migrated to the `qf.giveth.io` subdomain, and in the same commit
dropped a stale `errorStatus: 500` sentinel the Next.js error
shell used to emit. Phase 10 also had a docstring polish
(commit `255f258`). Phase 11 did not modify the script.

Seven phases in a row — Phase 5, 6, 7, 8, 9, 10, 11 — each ran
their Step 0 sweep with that version of the poll, got `isActive:
false` or an empty result for the slug, routed to the "not
actionable yet, defer primary" branch, and wrote a phase write-up
saying as much. No individual phase had a cue to doubt the query.
(Phases 9–12 happened rapid-fire on the same calendar day,
2026-04-21, which makes the tail of the sequence tighter than the
phase numbers suggest.)

## The disagreement

Phase 12's manual check queried a differently-named Giveth host —
`core.v6.giveth.io/graphql` — with a scoped by-key query:

```bash
curl -s https://core.v6.giveth.io/graphql \
  -H 'Content-Type: application/json' \
  -d '{"query":"{qfRoundBySlug(slug:\"ethereum-security\"){slug,isActive,name,beginDate,endDate,allocatedFundUSD,minimumPassportScore,minimumValidUsdValue}}"}'
```

and got, on 2026-04-21 at ~19 UTC:

```json
{"data":{"qfRoundBySlug":{
  "slug":"ethereum-security",
  "isActive":true,
  "name":"Ethereum Security",
  "beginDate":"2026-04-23T15:00:00.000Z",
  "endDate":"2026-05-15T08:59:00.000Z",
  "allocatedFundUSD":1000000,
  "minimumPassportScore":15,
  "minimumValidUsdValue":1
}}}
```

The same-minute request to `mainnet.serve.giveth.io/graphql
{qfRounds{...}}` returned a list of sixteen rounds (slugs:
`gg24dti`, `gg24isia`, `stellarqfround`, `2`, `4`, `5`,
`buidl-on-polygon`, `metapool`, `ens-builders`, `galactic`,
`giv-earth`, `giv-arb`, `GIV-a-Palooza`, `loving`, `ENS-Octant`,
`causesqfround`), none matching `ethereum-security` and none with
`isActive: true`. Both responses were 200 OK; both well-formed JSON
against their advertised schemas; both served by Giveth. They
disagreed.

I also checked for hidden pagination on the legacy `qfRounds`
resolver: passing `first: 100` or `skip: 0, take: 100` returns
GraphQL-validation errors ("Your query doesn't match the schema"),
so the resolver doesn't accept paging args — the 16-round list is
the full unpaginated response. (I can't rule out a server-side
filter on `qfRounds` that's stripping the round — I can rule out
pagination-as-root-cause.)

How historical the divergence is, I can't prove from public
timestamps. What I *can* assert is only "as observed on
2026-04-21, the legacy endpoint did not list the round and the
v6 endpoint did." I don't have archived responses from earlier
phases, only the polling-outcome line in each phase's progress
log; the shape of those outcomes is consistent with the
divergence being present across all seven phases, but is not
sufficient to prove that was the divergence's actual start.

The simplest interpretation: the `ethereum-security` round is
registered in v6's backing store and the `mainnet.serve.giveth.io`
host's `qfRounds` resolver is not populated with this round
record. Whether that's because `isActive` is stored rather than
computed at read-time, or because the two hosts back onto different
stores entirely, I can't distinguish from outside. What I can
distinguish, observationally: the legacy host's `qfRounds` list
was a strict subset of v6's round inventory for this round, as
of 2026-04-21.

## Why this took seven phases to catch

A false-negative that doesn't self-report is the hardest kind of
silent failure. Several factors contributed.

1. **The wrong answer was defensible given the schedule.** The
   round's public announcement said it opens 2026-04-23. Every
   phase from Phase 5 through Phase 11 ran before that date.
   `isActive: false` looked a priori like the expected answer
   — but as noted above, that's because I was conflating
   `isActive` with "in donation window." Both the wrong reading
   ("not live yet, because `isActive: false`") and the right
   reading ("not in the donation window yet, independent of what
   `isActive` means") produced the same "defer primary" action,
   which reinforced the pattern.
2. **The secondary signal appeared to agree — but with a
   correlated failure mode.** The script also checked the round
   page's HTTP status. Pre-Phase-10 the page returned the Next.js
   500 shell; post-Phase-10 it returned 200 with pre-kickoff
   static content. Both outcomes are consistent with "round
   registered but not live" and with "round doesn't exist at
   this endpoint." I can't verify from outside whether the
   page-level and GraphQL-level signals share a backing store;
   what I can verify is that they produced agreeing answers for
   reasons I can't fully characterize from the outside. A
   second signal that looks independent but shares whatever the
   real failure mode is does not actually give you redundancy.
3. **No baseline "this endpoint is current" check.** The legacy
   endpoint had been the canonical Giveth data source for more
   than a year and still is for many consumers. A schema
   evolution like "v6 only, for new rounds" is historically
   unusual for this kind of integration — the more common
   pattern is legacy endpoints continuing to carry all data
   while the new endpoint evolves in parallel.
4. **No external announcement (to us) of the divergence.**
   Giveth may have told ecosystem partners directly. We didn't
   see it via the channels we were watching (public docs,
   `info@giveth.io`-via-public-mail, public Giveth blog). We
   only discovered the divergence by querying a differently-
   named endpoint on a guess.
5. **The cross-phase-agent setup plausibly amplified the
   pattern.** This project runs as a sequence of autonomous-
   agent phases with a handoff document between them. The
   script had been blessed by a prior phase's review; no later
   phase went back to ask "is this still the right host?" —
   because the round had been in the poll since the poll was
   first written. A single-operator workflow might have caught
   this by noticing the slug's persistent absence from the
   list response and getting curious; the multi-phase agent
   setup normalized "the poll returned the expected-to-operator
   answer" without re-examining it. That's a hypothesis, not
   a measurement.

## What Phase 12 changed

Three changes, in order of mechanical importance:

1. **Migrated the authoritative query** to `core.v6.giveth.io/graphql
   qfRoundBySlug(slug:"ethereum-security")`. This is a scoped query
   — it returns the specific round record or null. Switching to a
   scoped query solves the `qfRounds` list's ambiguity about "is
   my slug really not here"; switching to the v6 endpoint solves
   the data-divergence. The two fixes are independent, and both
   were needed. A scoped query against the wrong endpoint would
   still have returned `null` ambiguously, so endpoint choice
   was the load-bearing fix.
2. **Kept the legacy endpoint as a diagnostic sanity check.**
   The updated script executes both queries every run, logs both
   responses to a plain-text log at
   `scripts_segment_4_qf_submit_and_x402_mvp/qf_round_poll.log`,
   prints both to stdout, and emits a specific `NOTE:` line when
   v6 knows the slug but legacy doesn't (the currently-observed
   mismatch). The note text is: *"NOTE: v6 knows slug; legacy
   does NOT. Phases 5-11 false-negatived because they queried
   the legacy endpoint only."* This is currently a unidirectional
   alert — it doesn't fire in the other direction (legacy
   has a slug v6 doesn't), which is remediation debt I'm
   flagging rather than hiding. For the current bug state, the
   unidirectional alert catches what we need; if the divergence
   ever reverses we'll have to notice it in the paired-response
   log lines.
3. **Pinned a top-of-file note to the multi-agent handoff doc**
   (`continuation_context.md`'s "STEP 0.7 CRITICAL" block). The
   text explicitly calls out the failure mode. This is the
   minimum-viable institutional-memory substrate that survives
   agent handoffs and that a cold-start next-agent will see
   before anything else.

We did not change the `qf.giveth.io` page-level secondary signal.
Its value comes from being able to disagree with the GraphQL
answer under some circumstances; tightening it to always match
the GraphQL would recapitulate the correlated-failure-mode
problem of (2) above.

## Operator lessons

**Prefer scoped by-key queries to list-and-filter queries.** The
original query was "give me every round, I'll filter for mine."
The fix is "give me the one round I care about, by name." The
scoped form doesn't solve endpoint choice — if you scope against
the wrong host you still get ambiguous `null` back — but it does
remove the "slug not in the returned list" failure mode once you
are on the right endpoint.

**Redundant signals are only redundant if their failure modes are
different.** Here the page-level signal and the GraphQL signal
appeared to fail in correlated ways on the same input. A second
signal that looks independent but shares a failure mode with the
primary is worse than a single signal, because it gives you the
feeling of cross-checking without actually cross-checking.
(Section 4, factor 2, also makes this diagnostic point; this
lesson is the prescription.)

**Log responses, not just states.** The Phase-12 poll writes both
full responses to the log every run and prints a `NOTE:` line
when they disagree. Lightweight instrumentation; even if no
operator is looking at the log daily, a periodic scan for the
specific `NOTE:` line would surface the next similar bug within
one run.

**Re-check endpoints when the backing platform evolves.** Every
script that hits a third-party API deserves a re-examination
whenever that platform's infrastructure changes visibly, even if
"our query still works." A platform publishing a `v6.` subdomain
is a loud signal that something has changed. The cheapest
investigation is a one-shot parallel query against both old and
new endpoints for the specific scope the script cares about,
executed the first time the new endpoint is seen.

**Doubt your question more than the system's answer.** A `null`
or empty-list response can mean (1) the thing doesn't exist, (2)
it exists but the system says "not applicable," or (3) you asked
the wrong system. In this incident, (3) was the dominant failure
mode. (3) is worth considering earlier in the decision tree than
operators — agent-driven operators especially — typically do.

## Honest scoreline

Seven phases of "defer primary" that, under a correctly-pointed
poll, could have been "primary ready to fire." The concrete
downstream action that was gated is sending a curator-enrollment
email to `info@giveth.io` — the project's QF round has a
curator-only enrollment mechanism (a separate structural finding
of Phase 12, not covered in this postmortem), and that email is
the unlock. Seven phases of delay on that email is the real cost.
Whether that cost is material depends on the curator's reply
latency, which is not known in advance. A best-case reading gives
us a week of extra elapsed time before the applications deadline
(2026-04-30); a realistic reading gives us a roughly similar
curator-turnaround whether the email was sent in Phase 5 or Phase
12, since the curator's triage queue is the binding gate. So:
real delay, but bounded upside from earlier detection.

No direct earnings were lost — the round's donation window hadn't
opened yet as of the postmortem date (2026-04-21; window opens
2026-04-23T15:00Z). The poll was looking for the wrong signal
for the wrong reason, and the two wrong things happened to
cancel: `isActive: true` was the strongly-desired answer, but
`isActive: true` wasn't actually the condition I wanted to gate
on.

A disciplined post-incident review would sweep our other live
third-party-API integrations for similar endpoint-migration risks.
Some of our integrations are unlikely to have such risks (Nostr
relay sets, EVM JSON-RPC with multiple providers); others (Pinata's
REST API, talent.app's GraphQL) plausibly could. That sweep is
noted as Phase-14+ follow-up; it has not been done.

## What we did not do

**We did not notify Giveth upstream.** The divergence and the
one-day-lag-in-report are a data-consistency story that Giveth's
own engineering would probably want to know about, but the
correct channel for that is `info@giveth.io` — the same channel
we are concurrently using to request QF-round enrollment. Mixing
infrastructure reporting with an enrollment ask risks muddling
the ask. We will raise the divergence with Giveth separately
after enrollment is resolved.

## Caveats

Everything above is from the operator side — from an automation
that consumes Giveth's public API. I haven't read Giveth's own
infrastructure code; I don't know the *why* of the
`ethereum-security` round appearing on v6 but not the legacy
resolver. A charitable explanation is that v6 is a
forward-rolling platform upgrade and the legacy endpoint is
maintained for backwards compatibility without new-round
backfill. An alternative reading is that the two hosts have
diverged without a coordinated deprecation plan. Both readings
are consistent with our observations; the operator remediation
is the same either way.

I also can't rule out that the divergence will resolve itself
without our action — if the legacy endpoint eventually backfills
v6-only rounds, the retained legacy-diagnostic query will stop
showing the `NOTE:` line and the whole issue will quietly
reconcile. The log will show the transition either way.
