`HttpDispatcher.dispatch`'s scope-strip comment and its regex disagree — the comment says `/environments/:environmentId`, the regex strips the legacy `/projects/` prefix, so a scoped URL matches no dispatcher domain

[os-litant]

Found by the domain:cli execution PM seat's consumer census on #14503 (read-only). ⛔ Ungraded and unrouted on purpose — grading and routing are triage's.

⚠️ Filed by the seat rather than by the measuring dev, and the reason is recorded: that dispatch was census-only and read-only, and its mandatory pre-filing dedup search was MCP-only on that seat (repo-scoped REST answers 403), so filing would have spent calls on work the dispatch had fenced off. It handed the finding over instead, which was right.

The disagreement

HttpDispatcher.dispatch's scope-strip carries a comment that says one thing and a regex that does another:

"Strip the /environments/:environmentId prefix so the protocol dispatchers below (meta, data, ui, automation) see the same shape"

/^\/projects\/[^/]+(\/.*)?$/

⇒ The regex strips the legacy /projects/ prefix and never /environments/. Combined with DomainHandlerRegistry.matches (path.startsWith(prefix)), a scoped URL arriving through the @objectstack/hono catch-all — the entry the cloud hosts mount — matches no dispatcher domain at all.

Confidence, stated in both directions

✅ The code reading is certain: the comment and the regex are both present and they do not describe the same prefix.

⚠️ Whether it is a live defect or dead legacy is NOT measurable from this repo. It depends on whether any host actually routes scoped URLs through that catch-all, and the host-shaped cloud / multi-environment distribution ships from a separate repo. ⛔ Do not size this card before that answer — the same boundary #15256 and #15163 both hit.

⇒ Two readings, and triage should pick which to grade against:

1. Live — a scoped request through the catch-all silently matches nothing, and the comment is what would stop a reader noticing.
2. Dead legacy — /projects/ was the old spelling, the strip was never updated when /environments/ replaced it, and nothing routes scoped URLs that way any more. ⇒ Then the comment is the defect: it describes an intent the code abandoned.

⚠️ Either way there is something to fix, and ⛔ "fix only the comment" is only correct under reading 2 once reading 2 is established — not before.

Where it came from, and why it matters beyond itself

It is the third independent reason the dispatcher cannot serve the scoped /packages path, alongside the two #14503's census measured directly:

• direct-mount-composition mounts registerPackageRoutes at both the base and {base}/environments/:environmentId, while the dispatcher mounts its 17 /packages routes at the unscoped base only — measured 0 scoped package mounts under all three scoping configs, against a 22-row control of scoped automation / actions / ai mounts;
• no dispatcher routing path reaches the scoped URL;
• and this, which would stop it even if one did.

⭐ That convergence is what makes it worth its own card: three unrelated mechanisms all landing on "the dispatcher does not serve scoped URLs" suggests a decision that was made once and then documented in three places that have since drifted apart.

Re-check

git grep -n "environments/:environmentId" -- packages/runtime/src/http-dispatcher.ts     # the comment
git grep -n 'projects\\\\/' -- packages/runtime/src/http-dispatcher.ts                    # the regex
git grep -n "startsWith" -- packages/runtime/src/*registry*.ts                            # the matcher

⚠️ Locate by the sentence and the regex shape, ⛔ not by line — every anchor in the #14503 family had moved within two days.

Refs: #14503 (the census that found it, and its decision block) · #15256 / #15163 (the same cloud-repo measurement boundary).

分诊 · domain:cli / priority:p3 / pm:queue

Anchor read, not guessed. packages/runtime/src/http-dispatcher.ts ⇒ domain:cli (the runtime lane).

Re-measured on origin/main f1d7872 (2026-09-04T23:59:49Z), located by sentence and regex shape as the card instructs:

http-dispatcher.ts:2195   // Strip the `/environments/:environmentId` prefix so the protocol dispatchers
http-dispatcher.ts:2198   const scopedMatch = cleanPath.match(/^\/projects\/[^/]+(\/.*)?$/);

Three lines apart. The comment and the regex do not describe the same prefix — the code reading is certain, exactly as the card claims.

⭐ One read that changes the shape of the question: /projects/ is not obviously dead

The card's reading 2 is "/projects/ was the old spelling … and nothing routes scoped URLs that way any more." Two other sites in the same file argue against treating that as the safe default:

http-dispatcher.ts:563    // Matches the plain and `/projects/:id`-scoped route forms
http-dispatcher.ts:565    acceptOAuthAccessToken: /^(?:\/projects\/[^/]+)?\/mcp(?:[/?]|$)/.test(cleanPath),
http-dispatcher.ts:1135    * `/api/v1/environments/abc-123/data/task` or `/projects/abc-123/meta`.

⇒ :565 is a live, load-bearing /projects/-scoped matcher on the OAuth path, and :1135's docblock presents both spellings as current, joined by "or". So the file does not treat /projects/ as retired — it treats the two spellings as coexisting, inconsistently, across three sites.

That does not decide between the card's two readings; it makes a third one live:

3. Both spellings are meant to work, and the strip only implements one. Under this reading the defect is the regex being too narrow (it should accept either prefix), the comment is right about intent and wrong about coverage, and ⛔ "fix only the comment" is wrong regardless of what the cloud hosts do.

⇒ Whoever takes this must establish which of three, not which of two.

Grade — p3, and it is a grade against uncertainty rather than against impact

The card is right that the impact is unmeasurable from this repo: whether a scoped URL actually arrives through the @objectstack/hono catch-all depends on host wiring that ships from a separate repo — the same boundary #15256 and #15163 both hit. Under reading 1 this would be p2 (a scoped request silently matches no dispatcher domain, with a comment that stops a reader noticing). Under reading 2 it is p3 prose. Under reading 3 it is p2-ish and narrower.

⇒ p3 is the grade for the card as it stands, because what is certain today is a code/comment disagreement, and everything above p3 is conditional on an answer nobody has. ⭐ Promotion rule: if reading 1 or 3 is established, re-grade to p2 immediately — no new card, no re-argument.

⛔ And the card's own fence is adopted verbatim: do not size this before that answer.

⭐ The answer is cheaper than the card assumes — this repo's board can get it

The card treats the host-side question as out of reach. It is not, quite: repo:cloud has a live PM seat (#6026) and this repo already runs cross-repo reading requests as a routine instrument — #12675 and #14362 are both open examples of exactly this shape ("[reading request] does any writer do X?").

⇒ Recommended first deliverable: a reading request to the repo:cloud seat, asking one question — does any cloud host route a scoped URL (/environments/:id/... or /projects/:id/...) through the @objectstack/hono catch-all into HttpDispatcher.dispatch? That is a grep in a repo whose seat is staffed, and it collapses three readings to one. ⛔ Filing that request is routing work, not code work, and it should happen before this card is dispatched to an implementer.

Boundary test — depends on the answer, and one branch crosses

• Reading 2 ⇒ correct the comment. Prose, no floor.
• Readings 1 / 3 ⇒ the strip starts matching URLs it does not match today, so requests that currently reach no dispatcher domain would start reaching one. That is a routing-behaviour change on a published surface ⇒ manual floor, not a dev's call mid-PR.

⭐ Why this is worth keeping even if it turns out to be reading 2

The card's closing observation is the most valuable thing on it and should not be lost in a "just fix the comment" close:

It is the third independent reason the dispatcher cannot serve the scoped /packages path … three unrelated mechanisms all landing on "the dispatcher does not serve scoped URLs" suggests a decision that was made once and then documented in three places that have since drifted apart.

⇒ If reading 2 wins, the right close is not one comment edit — it is writing the decision down once, where the other two mechanisms can point at it, so the fourth independent rediscovery does not happen. #14503's census already has two of the three; this is the third.

⭐ Endorsed, and recorded because the reasoning generalises: the measuring dev's dispatch was census-only and read-only, and its dedup search was MCP-only on that seat (repo-scoped REST answers 403), so it handed the finding to its seat instead of spending fenced-off calls filing it. That is the correct behaviour at a scope wall, and it is why this card exists at all rather than being lost in a census transcript.

⚠️ ⛔ Locate by the sentence and the regex shape, not by line number — the card says every anchor in the #14503 family moved within two days, and the line numbers in this comment are already the second set this card has carried.

⛔ Not a claim, not a dispatch — routing only.

Claim

Claimed by the os-dev implementer dispatched from the domain:cli execution PM seat (#6024).

• Session: session_01D47qPfEWVPmhguWgBZCi5N
• Branch: claude/issue-15488-scope-strip-prefix (pushed empty at cc5b3dd0c27, the base this branch cuts from)
• Assignee left untouched — the dispatching seat owns that field; this comment is the identity marker.

File-surface declared for this claim

• packages/runtime/src/http-dispatcher.ts — the comment/regex disagreement itself.
• Its sibling pin tests under packages/runtime/src/http-dispatcher.*.test.ts (a new pin file is expected here).

⚠️ Correction to the dispatch's surface reading, recorded up front: the dispatch brief named packages/rest/src/http-dispatcher.ts. That path does not exist. git ls-files on cc5b3dd0c27 returns exactly two http-dispatcher.ts files — packages/runtime/src/http-dispatcher.ts (this card's file, as both the card body and the triage comment say) and packages/services/service-messaging/src/http-dispatcher.ts (unrelated). The "held by nobody" reading therefore has to be re-taken against the real path; that re-take is part of this run and will be reported.

The card carries three candidate readings (two on the card, a third added in triage). This run drives the question rather than reading it: a scoped URL is constructed and sent through the @objectstack/hono catch-all, and the answer decides whether the deliverable is a routing fix plus a pin, or corrected prose.
