Stop the graph-update payload dropping documents it cannot see#552galshubeli wants to merge 2 commits into
Conversation
A rename from `.md` to `.mdx` reported the addition and dropped the deletion. `_collect_md_changes` tested one suffix on both sides of a rename, and the Mintlify migration swapped that suffix `.md` -> `.mdx` symmetrically, so the delete-half stopped matching anything: the payload for #544 read `+190 ~0 -0` while the merge had renamed 151 files and deleted 112. Those 202 pre-migration documents are still in the live graph, and because the workflow only triggered on `**/*.mdx`, no future push could evict them either. Two suffix sets instead of one. INGEST_SUFFIXES is what the graph ingests; TRACKED_SUFFIXES is what may already exist in it as a document. A rename out of the tracked set is a deletion whatever the destination is. While in here, the other ways this script could lose a document without saying so: - an unreadable blob was skipped and the run reported success. Now it fails the step and names the paths. - an unreachable `github.event.before` (force-push) died on a raw CalledProcessError. Now it fails with what to do about it. - an oversized payload was discovered as a proxy error minutes into the upload. Now it fails here, with the byte count. - `C` (copy) and `T` (typechange) were ignored, so a copied page was never ingested. The payload also carries `head_sha` and a `manifest` of every ingestable path at head. Both are inert against the current server, which ignores unknown fields -- they are what will let it reconcile its document set instead of trusting a diff it cannot verify. 15 tests, and the two that cover the rename fail against the pre-fix logic and nothing else.
Four things the workflow could not do.
**Deletions of pre-migration pages never triggered it.** `paths` listed
only `**/*.mdx`, so a commit that removes a `.md` page was invisible and
the document stayed in the graph. `.md` is in the filter now.
**The outcome went nowhere.** The response carries `promoted_graph` and
the three counts, and all of it was discarded into raw log output; a red
job said nothing about whether anything published. There is a step
summary now with the diff counts, the payload size, the HTTP code and the
response body -- including the case that actually happened on 17 Aug, a
closed connection whose run published 2h23m later, where the honest
answer is "outcome unknown, check the server log before re-running".
**The token was interpolated into the script text.** `${{ secrets.* }}`
inside `run:` puts the secret in the process table. It goes through `env`
now.
**A missing `GRAPHRAG_UI_URL` POSTed to a bare path** and failed
obscurely. Both the variable and the secret are checked first.
Also `--no-progress-meter`: the upload previously wrote ~300 progress
lines into every job log, which is most of what you scroll through when
reading a failure. And comments that say what `--max-time` and the
concurrency group actually do -- the platform closes the connection at
~300s whatever curl is told, and the group only serialises CI jobs while
the server keeps working after the job exits.
Adds update-graph-check.yml: builds the same payload on the PR and prints
the counts, without calling the server. `+190 ~0 -0` existed nowhere a
reviewer could see it before merge.

Pull request overview
Improves the reliability and observability of the docs “update graph” automation by correctly tracking deletions/renames across .md → .mdx migration scenarios, hardening failure modes, and adding PR-time validation of the generated payload.
Changes:
- Fixes diff/payload construction to distinguish ingestable (
.mdx) vs tracked-for-eviction (.md,.mdx) documents, preventing silent “missing deletions”. - Hardens the workflow + script behavior (explicit failure on unreadable blobs/unreachable base/oversized payload; safer token handling; clearer step summaries).
- Adds a PR workflow to build and summarize the payload without calling the server, plus unit tests for the payload builder.

git path quoting corrupts both the diff parse and the manifest. core.quotePath defaults to true, so git diff --name-status and git ls-tree --name-only escape any path with non-ASCII or special bytes, for example "guides/gu\303\255a.mdx". The script then uses that escaped name as a real path.
.github/scripts/build_diff_payload.py#L145-L163: the escaped path fails in_read_at, lands inunreadable, andmainexits 1, so one accented filename blocks every graph update.

Require an https endpoint before sending the bearer token.
The step checks that GRAPHRAG_UI_URL is non-empty, but not its scheme. If the repository variable holds an http:// URL, curl transmits Authorization: Bearer $UPDATE_GRAPH_TOKEN in cleartext. Validate the scheme and constrain curl to https.

Why
The Mintlify migration sent this payload to the graph:
190 additions, zero deletions — from a merge that renamed 151 files and deleted 112. The result is that the live docs graph holds both copies of every page: the 190 new
.mdxdocuments and the 202 pre-migration.mdones, which no future push could ever evict.One line did it.
_collect_md_changestested a single suffix on both sides of a rename, and the migration swapped that suffix symmetrically:if status == "R" and len(parts) >= 3: old, new = parts[1], parts[2] - if old.endswith(".md"): # old paths ARE .md — used to match + if old.endswith(".mdx"): # nothing on the delete side matches now deleted.append(old)The
paths:filter got the same treatment, so a commit that only deletes.mdpages no longer triggered the workflow at all.What changed
Two suffix sets, not one.
INGEST_SUFFIXES(.mdx) is what the graph ingests.TRACKED_SUFFIXES(.md,.mdx) is what may already exist in it as a document. A rename out of the tracked set is a deletion no matter where it went, and.mddeletions trigger the workflow again.Nothing is dropped silently any more. Each of these used to produce a payload that was quietly missing a document while the run reported success:
git showfails for a blobevent.beforeunreachable (force-push)CalledProcessErrortracebackC(copy) /T(typechange)The payload gained
head_shaand amanifestof every ingestable path at head. Both are inert against the current server (unknown fields are ignored), and they are what will let it reconcile its own document set rather than trusting a diff it cannot verify. A diff-only protocol cannot repair a deletion it never heard about — and now it has had to.The workflow says what happened. The response carries
promoted_graphand the three counts and all of it went into raw log output; a red job told you nothing about whether anything published. There is a step summary now — diff counts, payload size, HTTP code, response body — including the case that actually occurred on 17 Aug: a connection closed at 300s whose run published 2h23m later, where the honest report is "outcome unknown, check the server log before re-running, because a re-run starts a second full ingest".Hardening: the bearer token moves out of the interpolated script text into
