Changes touching this path

• the beacon counts PEOPLE where the log can only count requests, and the notice that describes it was rewritten in the same change because deploying one without the other publishes a falsehood loot#1757, over loot#1620 and loot#1617. POST /api/beacon takes one short message per view and derives SHA-256(daily_salt || ip || ua || site) truncated to 16 bytes, in process, discarding both inputs. It is canonical for uniques and sessions and for nothing else: the log stays canonical for volume, because it sees the ~53 prerendered pages, the cache hits and curl, none of which run any JavaScript. Two sources counting volume would be two numbers to reconcile. The key is length-prefixed per field rather than concatenated, and that is a real defect closed rather than a flourish. One of the fields is the User-Agent, which the CALLER chooses: with plain concatenation ip=1.2.3.4 ua=5 and ip=1.2.3.45 ua= hash identically, so a visitor could be merged onto a neighbour. The mutation that drops the framing reddens exactly that pin and nothing else. Two decisions are recorded rather than defaulted. NO SALT, NO ROW: a beacon row without a key adds to a count of beacon rows while contributing nothing to the only two things this source is canonical for, so it would trade what we came for against a number competing with the log. And the module is EAGER, which is the answer to the ticket first hazard - ADR 0071 weighs the document plus eager assets, so a deferred chunk is paid by every visitor and counted by nobody. Measured at ~450 B on each of 62 surfaces and RECORDED, and loot#1640 is the precedent that makes this more than taste: it measured a lazy route at 581 bytes against 270 eager. The edge half is new and had to be, because this is the site first unauthenticated row-writing endpoint and the site vhost had no rate limiting at all. limit_req at the /api/ PREFIX, not at /api/beacon, so ADR 0074 telemetry arrives protected rather than silently exposed. Idempotence is remove-then- reinsert between markers, and loot#1647 install-detect arm is closed in the same patch since it needed the same only-if-absent vhost step. Its ordering is load-bearing: the blanket header insert runs while only hand-written blocks exist, which makes a duplicate unrepresentable instead of guarded against. Found by RUNNING it, which is the whole argument for the fixture: the marker ended in (generated), which awk read as a GROUP, so the strip silently never fired - the second run appended a second /api/ block while grep -v tore the limit_req line out of the first, leaving a vhost that would have failed nginx -t on the box. Pinned now, with a control proving the predicate can say no. The notice had to move with the code. Five published statements would have gone false, the worst being that these records carry no key and nothing links two requests to the same person. Rewritten to lead with the key, say the secret is DESTROYED rather than merely rotated, and disclose that a visitor spanning midnight is counted twice. FOUR more contradictions were then found only by RENDERING the page, which is the third time that has been the only thing that worked. Objecting still said the log is the only thing we collect from, so this control has nothing to suppress - three paragraphs after the new text says the browser sends nothing when you object. Erasure and Your rights both still claimed nothing is keyed to you. And JSX drops a newline beside a tag, so the page shipped visitorkey and notstored as single words. The font gate then caught a star glyph absent from the shipped subset, which would have rendered as tofu. A test that asserted we do NOT collect a visitor key survived all of this green, because its regex matched one verb phrasing the new prose never uses. It is inverted now: the page MUST name the key, MUST say destroyed, MUST disclose the midnight double-count. Leaving it would have let a later edit delete the disclosure and stay green. 532 site tests, 322 scripts tests, budget green with the notice raise on the record. 3c22dcae · dbf3dbe6…

Renames are not followed. loot's tree maps a path to an address, so a rename is a delete and an add. This list is the history of the name, not of the bytes.
