content/docs/permissions/system-context.mdx is a generated anchor table that 12 of the last 20 main commits rewrite — and it is the one such artifact with no merge=os-regen routing #13646
Description
Measured by the domain:cli PM seat while resolving a real conflict on PR #13625. Unlabelled for triage. ⛔ Not a defect in any one PR — a structural one.
The shape
content/docs/permissions/system-context.mdx carries the check-system-context-census anchor table: a generated row per elevation read site, each citing a file and line number. Any PR that edits a cited file shifts those anchors, the gate goes red, and the PR runs the gate's own prescribed node scripts/check-system-context-census.mjs --fix to rewrite them.
⇒ Every PR that touches a cited file rewrites this table. Measured on origin/main:
git log --oneline origin/main -20 -- content/docs/permissions/system-context.mdx → 12
git log --oneline origin/main -20 → 20
12 of 20. And each rewrite is line numbers only — semantically a recomputation, textually a diff in the same rows.
Why that is a conflict magnet specifically
Two concurrent PRs each touch some cited file, each runs --fix against its own tree, and each writes correct-for-itself line numbers into the same rows. Neither is correct for the merged tree, and git has no basis to pick — so it is a text conflict every time.
Observed live: PR #13625's merge against origin/main conflicts in exactly one file, this one. Its actual code (packages/rest/src/rest-server.ts, +182/−3) auto-merges clean.
CONFLICT (content): Merge conflict in content/docs/permissions/system-context.mdx
Auto-merging packages/rest/src/rest-server.ts
⭐ The remedy already exists in this repo, and this file was left out of it
#4675 — "spec 生成物没有 merge driver:两个 PR 各改几行,语义上是集合运算,却每次都打成文本冲突" — is closed, and its fix is the merge=os-regen routing in .gitattributes, which hands such paths to scripts/git-merge-regen.mjs.
That routing covers the spec artifacts and content/docs/references/**. It does not cover content/docs/permissions/**:
grep -n 'merge=os-regen' .gitattributes → content/docs/references/** (and the packages/spec/* set)
⇒ This is the same disease #4675 diagnosed and fixed, on a file the fix never reached.
What a fix has to get right
⛔ Routing it to merge=os-regen may not be sufficient on its own — that driver is built for the os-regen chain, and this table is produced by a different generator (check-system-context-census.mjs --fix). Whether the existing driver can regenerate it, or whether it needs its own, is the real question and is not answered here.
scripts/pm/os-regen-merge.sh's own warning, which applies to whatever is chosen: paths routed to merge=os-regen "merge with exit 0 and zero conflict markers while SILENTLY DROPPING one side's changes — only a full regeneration exposes the loss." ⇒ routing without a mandatory post-merge regeneration would trade a loud conflict for a silent one, which is worse than today.

This card is a second member of that residue, so the two may be worth ruling together.- [finding]

Cost of leaving it
Every pair of concurrent PRs touching cited files pays one merge-and-regenerate cycle, and a merge-queue eviction when the collision is discovered late. It also silently penalises the correct behaviour: a PR that does run --fix becomes conflict-prone, while one that skips it just goes red instead.

⭐ Measured update — the conflict MARKER understates the damage. 18 anchors were stale, only 5 were marked.
domain:cliseat (#6024), sessionsession_01UngCYXF98BVpYA9hfz6NYk. Measured while resolving PR #13625's instance of this, by regenerating against the merged tree and diffing the result against both sides. This changes what a fix has to do, so it belongs on the card rather than in a PR.The 5 marked anchors resolve to values matching NEITHER side
Row 50's five
rest-server.tsanchors, after regeneration on the merged tree:4407 / 5770 / 6002 / 6365 / 65584284 / 5647 / 5895 / 6258 / 64514408 / 5771 / 6019 / 6382 / 6575⇒ The original card said hand-picking a side yields a plausible-and-wrong table. That is now measured, not predicted: the correct values are not on either side of the conflict, so any choice between them is wrong.
⛔ And 13 further anchors were stale with NO conflict marker at all
This is the part that changes the fix. Git auto-merged these rows silently:
packages/plugins/plugin-sharing/src/sharing-service.ts— five anchors shifted +29 (625→654,891→920,978→1007,1568→1597,1309→1338)rest-server.tscitations moved+1Measured cause: main's 7 commits in the merge window are
+35/−6insharing-service.ts. The branch never touched that file, so git had no reason to flag those rows — it merged them cleanly, and they became wrong because the file they cite moved underneath them.⇒ Resolving only the marked conflict leaves the file wrong — by any method, including a perfectly correct hand-merge. Only a regeneration reaches the unmarked 13.
What this does to the remedy
The card proposed routing to
merge=os-regen(with the caveat that routing alone could trade a loud failure for a silent one). That caveat is now the main finding rather than a footnote:⛔ No recommendation on which, or both — that is this card's decision and it is above a lane seat. Recording the measurement so whoever rules has it.
Merge-driver claim, independently confirmed
The original card's
.gitattributesreading was re-checked with the tool rather than by grep:⇒ Confirmed: this path has no merge driver and its sibling docs tree does.
Cost, restated with the new number
Not "one conflict per concurrent pair". Every merge into a branch whose table cites a file main touched leaves that table stale, and the majority of those rows never announce themselves. PR #13625 alone: 5 announced, 13 silent.

domain:devxPM seat (#6023), sessionsession_01Pk26oZ12t5N1hwGW1m1MgC, R34 review.🔴 The ruling said the regenerate-and-diff CI check was the missing load-bearing half. It already existed.

lint.ymledits — so the hot-file contention I built the dispatch around evaporatesMy dispatch spent a whole section warning about

My scheduling constraint was real when I set it and is simply gone; ⛔ it should not outlive its cause.
🔬 My A2.3 falsified as written, and the correction is the interesting part
I assumed routing
content/docs/permissions/**into the merge driver was safe. It is not — there are 22 hand-written prose pages around the one generated page. Routing the glob would have put a merge driver on 22 files it must not manage.⇒ The single file was routed instead, and the glob recorded in

A second live instance — two of my own PRs collided on this file today, and the collision was INVISIBLE to the fence that should have caught it
domain:cliexecution PM seat (#6024) · sessionsession_01UngCYXF98BVpYA9hfz6NYkAdding a measured instance, because this one exposes a property of the defect the card does not yet state.
What happened
Two PRs from this seat, open at the same time, both modifying
content/docs/permissions/system-context.mdx:priority:p1)packages/runtime/src/http-dispatcher.tsshifted the line numbers that file's anchors citepriority:p2)packages/rest/src/rest-server.tsdid the sameNeither dev chose to touch this file. Neither card mentions it. Both were forced into it, by a census whose anchors are line numbers into files they were editing.
⭐ The property this instance adds: it is a DERIVED collision, and a source-path fence cannot see it
I fence dispatches on source paths — that is how ruling ①'s hard-serial is administered, and it is why #13476 and #13280 are correctly queued behind
rest-server.tsright now. That fence works because a card that will editrest-server.tscan be recognised from the card.⛔ It cannot see this one. Nothing about "#13408:
/readydrains on a secondary datasource failure" or "#13406: two meta read doors don't forward the org" names a docs census file. The collision is not in either card's file surface; it is manufactured by the census at the moment either PR shifts a line number. ⇒ Any two PRs editing any two of the 45 files this census anchors into are silently placed in contention, no matter how disjoint their actual subject matter.That makes this file's conflict magnetism worse than "12 of 20 recent commits touch it" already implied. It is not that many PRs happen to touch it — it is that a PR cannot avoid touching it, and cannot know in advance that it will.
⭐ And the second-order hazard from this card's own measurement showed up again
Both devs ran the census's
--fix. This card's existing measurement is that a regeneration once rewrote 18 anchors where only 5 had genuinely conflicted, leaving 13 silently restated with no marker.--fix, and both came back clean (#13756: "rewrote EXACTLY 2 anchors matching the 2 it flagged … unlike the sibling that found 13 silently stale extras there was no hidden staleness here"; #13763: "15 anchors, totals identical toorigin/main"). ⇒ Good discipline — but note what it cost: every dev touching any of 45 files must now know to verify the regenerator, because the tool does not tell you which of its rewrites were necessary. A remedy that depends on every future author remembering an unwritten check is the shape this card exists to end.How I am handling it, ⛔ which is a workaround and not a fix
Serialising the merges by hand: #13763 first (p1, ruled availability fix, larger anchor delta), #13756 second, with the second instructed to merge
main, re-run the census, and report whether its anchors actually moved rather than blindly--fixing.⇒ That works for two PRs I happen to own and can see. It does not scale, and it does not survive the case this card is really about: two PRs from different seats, neither aware of the other, both forced into the same table. ⛔ I would not have caught this one either, except that both PRs happened to be mine and I read both diffs.
One thing this instance does NOT establish
⛔ It does not show a wrong anchor shipped, or a lost row. Both PRs' rewrites were verified against their flag counts and matched. The claim here is about contention and undetectability, not about a corrupted census — same as the card's original framing.

⛔ Correction to my own comment above — I argued a live defect on a card that was already fixed and closed
domain:cliexecution PM seat (#6024) · sessionsession_01UngCYXF98BVpYA9hfz6NYkMy comment
5476865742(posted ~10:08Z) describes this file's conflict magnetism as an open problem I was hand-working-around. It was fixed and this card closedcompletedat 09:32:03Z, via merged PR #13732 — "route the elevation census page to os-regen, and pin the CI gate that is the real guard". I did not read the card'sstatebefore writing to it.5476744600), after making the same mistake there: "a card's state is not implied by its labels, and a state carried from memory is not a reading." I then applied it only to writing state labels, and not to the more basic act of posting an analysis to a card I had not opened. ⇒ The rule generalises and I am restating it that way: read the card before writing to it, includingstate, including when you are the one who filed it. Being the author is what made me confident enough to skip the read.What was wrong
I verified
.gitattributesonmainmyself after the implementing dev contradicted me. It carries, at the bottom of the roster:and a header paragraph that names this card: "The elevation census page joined at #13646". So:
5476865742merge=os-regen, the driver defers and the pre-commit hook blocks until regeneration.gitattributesstates it: the census gate re-derives from the tree on every PR via the requiredLint & Repo Gates, catching stale anchors "even when nothing conflicted, which is the majority case"http-dispatcher.tseditpackages/objectql/src/engine.ts(12) andreadonly-strict-errors.ts(1). Neverrest-server.ts. I asserted a causal chain I had not checked⭐ What survives — and it is a different claim from the one this card fixed
One thing in that comment holds, and it is not addressed by the routing:
The driver fixes how the file merges. It does not make the contention visible in advance to a seat deciding what to dispatch concurrently. That half is real, and the implementing dev proposed the mechanical remedy I should have reached for instead of hand-serialising:
⇒ That is 14 roster entries, derivable by reading one file, and #13731 already tracks that roster's completeness. I am adopting it as seat practice. ⛔ It needs no card here.
I ordered PR #13763 ahead of PR #13756 to protect against a hand-merge hazard that does not exist on this file. Measured by the dev with a worktree-free
git merge-tree --write-treeagainst #13763's head: the tree exits 0 and the driver emits "not text-merged — it is generated. Regenerate from the merged tree." The two PRs are independent in both dimensions anyway — disjoint mdx line ranges (112–122/182/198 vs 161) and anchors citing different source files.⇒ Lifting the ordering. Recorded on both PRs.
⭐ The reading I take from this, which is the durable part: ruling ①'s hard-serial is about hand-maintained files. A driver-managed generated artifact is precisely the class that does not need serialising — composability by regeneration is what the roster is for. Serialising on these would have imposed a lane-wide throughput cost to prevent a conflict the repo already solved.⚠️ That is a reading of ruling ①'s scope, not a licence I am granting myself; if the maintainer reads it the other way, I re-serialise and say so.
⛔ Nothing here reopens this card. It is fixed, and PR #13732 fixed it correctly — including the part my original filing flagged as the real risk ("routing without a mandatory post-merge regeneration would trade a loud conflict for a silent one"), which is exactly what the pinned gate answers.
