v0.11 item 2: the anchor, a page of its own, and two overclaims corrected - #33

… entry it pays The generators pick up `StateStore.receipts()` returning `Receipt | UnreadableReceipt` and the line numbers item 1 moved. ROADMAP's known-limitation entry for the malformed value is closed, with the two corrections implementing it earned: it listed G11 among the blinded readers, and `ctrlrun verify` grades G11 against a scratch store no UPDATE reaches; and it omitted the operator MCP server, which is a network surface.

CI installs the kernel as [dev,gateway,otel,identity] and no postgres extra, so it collects 6,096 where a local checkout with psycopg installed collects 6,172. The committed block is the one CI checks, so it is generated where CI generates it. Signed-off-by: arpan <contact@arpanghoshal.com>
CTRLRun/ctrlrun#200 merged with no paired docs branch, so main's docs job has been red since: the api reference and CLAIMS.md both cite line numbers that moved when _read_receipt grew, and the readiness block counts the eight tests it added. Branched from v0.11/1-unreadable-receipt rather than main, so merging this lands item 1's pages and these together and main goes green in one step. Signed-off-by: arpan <contact@arpanghoshal.com>
The three quoted `ctrlrun verify` transcripts are refreshed from real runs against their own policies, not edited: docs/verify.md against examples/authority/payments.yaml, and the CI guide and cookbook page against the policy each of them quotes. ROADMAP's 'nothing yet proves' sentence is closed, with the methodology error the proof made first: PYTHONPATH is inherited by every child, so all five released wheels imported the build under test and the run reported one schema version while looking exactly like a pass. Signed-off-by: arpan <contact@arpanghoshal.com>
docs/production/anchoring.mdx is a new page rather than a section of receipt-integrity, because that page is a 'what to run' page on a 900-word budget and the anchor's limits need as much room as its claim. Two overclaims corrected. OWASP-SOLUTIONS-LANDSCAPE said the anchor catches 'truncation and append'; an append lands above every anchored seq and is not detected, which is what SPEC-v0.11 §2.4's table settled. OWASP-AGENTIC-TOP10's G11 row said 'v0.6 has no anchor and claims none', which is no longer the milestone's position. All three quoted ctrlrun verify transcripts re-run against their own policies.

Cite deny or remove it from the claim.
The claim names ctrlrun deny, but the code column cites effects instead and gives no deny implementation reference. Add the deny citation, or include effects in the quoted command list if that was intended.

Update the not-applicable explanation.
The transcript now lists 12 not-applicable guarantees, but Lines 124-126 still say “Four guarantees are not applicable” and list only four. The page gives conflicting counts. Update that paragraph with the new transcript.

| **An append is still not detected**, and this is the half most likely to be misread. A forged receipt lands at head + 1, above every anchored `seq`, so nothing stops reproducing, and a later anchor freezes the forged chain as readily as an honest one. Receipts written and erased entirely **between** two anchors are not detected either, because they were never at or below an anchored `seq`. An earlier version of the roadmap said the anchor closed "a suffix erased or appended"; a review ran both cases and it closes only the first. | ||

Scope the malicious-administrator limitation to the unanchored interval.
Line 183 states that changing a row at or below an anchored seq produces anchor_broken. Line 187 then says that an administrator who rewrites every row, including the chain head, can recompute the chain and it verifies. These claims conflict when the external anchor record remains trusted.
Limit this exception to an administrator who can also rewrite the anchor record, or to changes in (last anchored seq, current head].
Proposed wording
- What it does not close is authorship, and it does not close a database admin who can rewrite every row including the chain head: such an adversary recomputes the chain and it verifies.
+ What it does not close is authorship, or a database administrator who can also rewrite the external anchor record. If the anchor record remains trusted, rewriting a row at or below the anchored `seq` produces `anchor_broken`; changes in `(last anchored seq, current head]` remain exposed until the next anchor.📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Pairs with the item 2 kernel branch of the same name. v0.11 item 2: the anchor.
This stacks the whole open docs chain (#30 → #31 → #32 → this). Merging this one lands every earlier one and makes
main'sdocsjob green, which it has not been since kernel #199 merged ahead of its docs branch.Two overclaims corrected, and they are the reason to read this diff
docs/OWASP-SOLUTIONS-LANDSCAPE.mdsaid the anchor catches "truncation and append". It does not catch an append. A forged receipt lands at head + 1, above every anchoredseq, so no anchored pair stops reproducing and a later anchor freezes the forged chain as readily as an honest one.SPEC-v0.11.md§2.4 settled this after a review ran both cases, andT531now runs a forged append and requires both reports to stay clean, so the limit is a tested property rather than a sentence. This document is the OWASP submission, so the claim was going somewhere that matters.docs/OWASP-AGENTIC-TOP10.md'sG11row said "v0.6 has no anchor and claims none". True when written, and not the milestone's position now. It says instead thatG28closes the erasing half and not the appending half, and thatG11itself is untouched, which isSPEC-v0.11.md§8.1's whole argument.A new page rather than a longer one
docs/production/anchoring.mdx. The obvious home wasreceipt-integrity.mdx, and the first draft put it there: that page went from 880 words to 1138 against a 900-word budget.The budget is the right answer rather than an obstacle.
receipt-integrityis a what to run page, and the anchor's limits need as much room as its claim — an anchor is the first thing in this project a reader could mistake for tamper-proofing. So the anchor gets a page with room for the table of what it does not catch, andreceipt-integritykeeps a four-line pointer.The page satisfies the section's own conventions rather than being exempted from them:
## What this does not do, aVerified byline namingT530,T530b,T531,T532,T533andT534, a link to Why and Get started, anSEO.mdrow, adocs.jsonnav entry and redirect. Its sentence "an anchor mints nothing and is not a signature" is added totest_docs_production.py's allow-list deliberately, which is what that allow-list is for.THREAT_MODEL.mdThe paragraph that has said since v0.6 that the chain closes neither truncation nor append now says what the anchor changes and exactly how far: the truncation measured at two statements is named, and so is the administrator who rewrites every row including the head, for everything at or below an anchored
seq. The malicious-administrator line is narrowed again rather than removed.It also carries the part most likely to be misread, in full: an append is still not detected, receipts written and erased between two anchors are not detected, the window is
(last anchored seq, current head], and an anchor is worth exactly what the record behind it is worth — a provider pointed at a file beside the database is worth nothing, which is the sentence this document already uses of a revocation feed.tests/test_release_documents.py'sT180allow-list is updated for the changed line and gains the new one, because an allow-list entry that stopped matching is an entry doing nothing.Generated
