…av (#104) The messenger had never been reachable. All three files sat on main since the zk-lotto forward-port, but Fresh resolves routes from the checked-in fresh.gen.ts and main's manifest registered neither, so /messenger 404'd there. Regenerating the manifest was the step that had been missed. Ports routes/messenger.tsx, routes/encrypted-messenger.tsx and public/js/messenger.js at main's tip, regenerates the manifest, repoints the nav's 'messaging' entry from /contact.html to /messenger in both PAGE_NAV and LANDING_NAV, and adds a canonical sitemap entry. Nothing from zk-lotto comes with it. Widens CI, which ran neither islands/ nor the new test: Nav_test's `PAGE_NAV points at nothing that does not exist` was passing locally and running nowhere, though it is the only guard against the exact failure this change could have caused. Confirmed it fires by reintroducing /lotto.html. Hardens the ported crypto against input it takes from an untrusted channel: the iteration count is bounded, an empty passphrase is refused, envelope fields are size-checked before decoding, and all validation runs before the PBKDF2 derivation rather than after it. Tests cover a real seal/open round-trip through the guards, a padded passphrase surviving untrimmed, a v1 envelope with no iterations field, a wrong passphrase being rejected, and the page's "no server plaintext" claim — asserted by proving the script has no way to reach the network. CI test step 35 -> 57 passing.
… audible The key box confirms delivery by POSTing to $RENDER_CALLBACK_URL/delivered. Setting that variable to the origin alone yields a 404, and notifyDelivered discarded the response without looking at it, so for months every confirmation failed silently: pdf_delivered_at stayed NULL and the 7-day shred clock never started. Checking res.ok is the whole fix — the status is not PII, and not reading it is precisely how this hid. The README now spells out that the path segment is load-bearing. The callback also no longer crosses the public internet. It used to leave the key box from a public IP, reach Caddy over TLS, and rely on a bearer token alone. a4t-keybox-tunnel.service carries both directions on one authenticated ssh channel instead — -L 8793 to push bundles out, -R 8794 for confirmations back — with both ends bound to loopback. ExitOnForwardFailure=yes is what makes that a guarantee: a tunnel that cannot establish both forwards exits and retries rather than running half-open with one direction quietly dead. Plain HTTP on 8794 is deliberate; ssh is the transport security and nesting TLS inside it buys nothing. The unit is committed exactly as installed, and carries a key path only, never key material. a4t-render.service documents why RENDER_WORK_ROOT is /tmp and not /dev/shm: PrivateTmp already gives the unit a private memory-backed /tmp, whereas Deno refuses every operation under /dev/shm without --allow-all, which would mean un-sandboxing the service to obtain a tmpfs it already has.

Two live faults, both silent in their own way. denomailer 1.6.0 failed every submission to Apple and leaked a second, unawaited rejection from its own socket reader. Deno exits on an unhandled rejection, so each failure killed the process mid-request: 251 crashes in one day, every one a respondent who submitted the gate and never got a link. lib/email.ts caught its own errors correctly the whole time; the one that mattered was never handed to it. romania/mailer.ts had already hit this and moved to smtplib -- the web tier just never got the same fix. lib/send_mail.py is that fix, deliberately near-identical to the key box's sender. The recipient travels in a 0600 file whose path is the only argv, and failures print one PII-free line -- smtplib's exceptions carry the envelope, and zero-logging has no exception for a stack trace. main.ts now suppresses unhandled rejections rather than dying on them. The mailer is python, but a background rejection must degrade one request, not end the process. Separately, getClientIp read the FIRST X-Forwarded-For entry. Caddy appends its peer rather than replacing the header, and no trusted_proxies is configured, so the first entry is whatever the client sent. Anyone could choose their own address: inflating QR scan counts at will, and walking past the contact form's 5/hour limit. It now reads the last entry, which is also correct where no proxy appends, since a single-element header has the same first and last value. The failure direction becomes an undercount instead of unbounded forgery. routes/api/contact.ts carried a private copy of that function, which is exactly how it kept the bug. The MERGE NOTE predicted this; the copy is gone and the note now records what happened. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…es them The report's "Unique Visitors" line has printed 0 for its entire life. It read request>client_ip, which the Caddyfile deletes before the line is written, so the set at :429 was never populated -- and it hashed with Python's builtin hash(), which is per-process salted anyway. This is a build, not a repair. The counter hashes in the Fresh app, never in Caddy: the proxy's remote_ip and client_ip deletions stay exactly as they are. What persists is integers. No digest, address or user agent reaches disk. The salt lives only in this process's heap, imported as a non-extractable CryptoKey and then zeroed, rotated on fixed 4h UTC boundaries. This is a deliberate departure from fresh_qr_salts, which keeps its salt in Postgres beside the digests it keys -- anyone with read access there can invert those by enumerating (IPv4, User-Agent) while the salt lives, and a DELETEd BYTEA survives in the heap page, the WAL, and every backup taken during the window. This host has no swap, so an in-memory salt has no disk form at all. Four hours because it divides 24 exactly, so a window never straddles midnight. Randomised interval lengths were considered and dropped: with nothing persisted there are no stored pseudonyms to align against a boundary, so unpredictability buys nothing, while variable windows make the over-count factor vary day to day and destroy the trend. The number is an UPPER BOUND on people, not an estimate, and the report says so. Someone returning in a later window is counted twice; a restart opens a new row and counts them again. The scheme can split one person into several but can never merge two into one. HyperLogLog was rejected: at this volume it is less accurate than exact counting, and a sketch supports membership probing, so it is not the one-way aggregate it looks like. Domain separation is enforced twice -- an independent salt in a different storage medium entirely, plus a domain tag first in the HMAC message, so the two pipelines could not collide even if someone later "cleaned up" the duplicated salts. Also in the report, since it was being touched anyway: - host filtering. One access.log carries every vhost, so every traffic number it has ever sent was a sum across aformulationoftruth.com, fobdongle.com, gimbal, proust, terra and the VPN panel. - the metrics fetch pointed at a dead port 8393; the app listens on 7268, so that request failed on every run and was silently swallowed. - a canary: zero recorded windows reports as RECORDER NOT RUNNING. A silent zero is exactly how the dead counter hid for so long. privacy.tsx claimed the logs hold "IP addresses (automatically rotated and deleted after 7 days)". They never did -- Caddy discards them at write time. Corrected, and the no-fingerprinting and no-profiling promises are pinned by tests, since this design only stays compatible with them for as long as nothing per-visitor is stored.

…econd link, and give the key box an id it can find Two independent faults, either of which alone means no PDF. A second magic link destroyed the work already done. createQuestionnaireSession closed the prior session, minted a new one at question zero in a freshly shuffled order, and left the ciphertext stranded under an id nothing reads -- deliver.ts selects WHERE session_id = $1 behind a lookup that filters completed_at IS NULL. buildBundle then backfilled the gaps as skipped:true, so the lost answers reached the PDF as blanks indistinguishable from questions the respondent had chosen to skip. Both call sites carried the same dead branch, logging "User resuming questionnaire" while doing the opposite; both arms called the same expression. A fresh session is forced -- session_id IS the HMAC of the resume token and the token is never stored, so an issued link cannot be re-derived. Starting over was not forced. The prior session's question order, answered_questions and current_index now carry across, and its answers MOVE to the new id: an UPDATE, not a copy, because the runtime role holds no DELETE grant on that table and a second copy of a respondent's ciphertext contradicts the shred design. The gate row travels with them. Answers are sealed to the per-submission keypair, and getSessionPubkey resolves exactly one pubkey per session, so carrying ciphertext while linking the newly minted gate row would have turned "answers missing" into "answers present and undecryptable". An advisory lock serialises two clicks on the same address; without it both readers see the same prior session and the second carries forward from one the first already emptied. The key box could never find an identity. gate-submit files it under the gate token -- pushIdentity(gateToken, ...) writes <gateToken>.key -- while render-service loaded it by bundle.sessionId, the session HMAC. Every one of the 1691 keys on the box is UUID-shaped and not one is 64-hex, so loadIdentity raised ENOENT on every render. That, not the tunnel outage, is why the site reports "PDFs returned, all time 0": no bundle has ever been decryptable. The bundle now carries keyId beside sessionId -- opened with the first, reported against the second -- and validateBundle refuses a traversal-shaped or missing one. The decision is extracted as planSupersede, a pure function taking the shuffle as a thunk so resuming cannot reshuffle even by accident; reshuffling re-points current_index at a different question and files the next answer against one the respondent never saw. Thirteen unit tests cover it, and there were none before: grep -rn "supersed\|completed_at" tests/ was empty. Suite: 196 passing against main's 180, with the same 45 pre-existing failures. romania: 31 passing, was 29.

Every test in this repo was a pure function or a source scan, so no test had ever crossed a stage boundary -- which is how a site reporting "PDFs returned, all time 0" for its entire life could not say which of a dozen stages was at fault. This one asserts the seams. Covered: the magic link carries both halves the verifier needs (the JWT it checks and the opaque token whose HMAC is the session id, which fail at different steps with error text that does not distinguish them); a complete walk yields all 35 answers with none blank; an interrupted walk is visibly incomplete rather than silently short, since buildBundle pads to the canonical length and a short document's gaps are indistinguishable from deliberate skips; the bundle names the key it must be opened with rather than the session; the password option travels sealed or is null, never an empty string that would ask qpdf to encrypt with nothing; and a respondent twenty questions in who requests another link keeps all twenty. gate-submit gains buildMagicLinkUrl and a magicLinkForTesting seam so the walk follows exactly the URL a respondent would receive, with nothing posted to a mail server. Email is the only stage not exercised. The database-backed case seeds a session, supersedes it with a second link, then runs deliver.ts's own read query against the new id and asserts nothing came back blank -- the assertion in the bug's own language. It is guarded on DATABASE_URL and is skipped here: this machine has no Postgres, no psql and no docker, so it is written but UNVERIFIED locally and needs a CI run or a local database to earn its keep. Suite: 203 passing against main's 180, same 45 pre-existing failures, no new ones.

… read from A third fault in the same "PDFs returned, all time 0" story, found by running the DB-backed test the previous commit shipped unverified. It needed a real Postgres to appear at all: nothing in the source reads wrong. question_index is BIGINT (migration 007, the only non-id BIGINT in the schema) and deno-postgres decodes int8 as a JS bigint, so every row arrives as 2n, not 2. Number.isInteger(2n) is false, so buildBundle's range guard rejected the FIRST answer of every real delivery with "question index out of range: 2" -- an index plainly inside 0..34, which is what makes the message so misdirecting. deliver.ts fed r.rows straight in, and queryObject<AnswerRow> is an unchecked cast, so the declared question_index: number was a claim nothing enforced. Fixed at both ends, because neither alone is load-bearing. The queries cast ::int so the annotation is true at the boundary; buildBundle takes number | bigint and normalises with Number() before the range check, so a future query that forgets the cast fails no differently. The range check still applies to the normalised value: widening what is accepted does not widen what is valid, and an out-of-range 99n is still refused. Dedup now keys on the normalised number too -- keyed on the raw value, a 2 and a 2n were two different Map keys and the duplicate guard would have missed the pair. Normalising on the way out matters as much as on the way in: the bundle is JSON, and JSON.stringify THROWS on a bigint rather than coercing it, so a fix that only relaxed the guard would have died one step later at pushBundle. Separately, DeliveryBundle in lib/romania-client.ts never declared keyId while buildBundle already returned it. The field travelled on the wire with nothing in the type system holding it there, so a later projection or spread that rebuilt the object would have dropped it and silently restored the ENOENT the previous commit fixed. render-service.ts's validateBundle already required it; this is the sending half of that contract. Clears four of the five deno check errors on this branch -- the fifth, SendEmailResult in lib/email.ts, is pre-existing on main and untouched here. Two new unit tests cover the bigint the driver actually returns and the out-of-range bigint, neither needing a database. The e2e query keeps mirroring deliver.ts exactly, ::int included, so it cannot drift into testing a query production does not run. Verified against PostgreSQL 16 with all 12 migrations applied: the DB-backed case now passes, so the previous commit's UNVERIFIED caveat is discharged. Suite 207 passing with DATABASE_URL set, same 45 pre-existing failures -- none of which import deliver.ts or questionnaire-session.ts. romania: 19 passing, 0 failing.

.github/workflows/ci.yml has not run once. It carried mangled conflict markers -- `##claude/repository-streamlining-myjlam` where `<<<<<<<` belonged, a bare `=======`, and a ` main` where `>>>>>>>` belonged -- leaving two `on:` keys and invalid YAML. GitHub does not report a broken workflow as a failed check; it reports nothing, so `gh pr checks` says "no checks reported" and the silence reads like a repo that simply has no CI. Confirmed: the committed file raises "while scanning a simple key" from a YAML parser, the replacement parses. 8ca0131 already fixed this on fix/report-window-coverage by restoring production's clean 77-line file, and that resolution is the right one -- it is what this takes as its base. It discarded the other side's Postgres service deliberately and said why: "no path in the test step touches the database ... reinstating a database service belongs with the first test that needs one." This branch is that test. So the service comes back, with the three things the discarded side never had and would have failed without: - a migration step. The service starts an EMPTY database, and without `deno run migrate.ts` the DB-backed case dies on a missing table rather than on anything it means to assert. migrate.ts prefers .env, which is gitignored and therefore absent in CI, so it falls through to the job env. - the test files named individually. `tests/` cannot be added wholesale -- the rest of it carries the ~449 pre-existing type errors the scope note already describes, and `deno test` type checks before running anything. These three are clean, so they run WITHOUT --no-check and get the type check for free. - only the env vars actually read, verified by running the paths under `env -i` with exactly those seven and nothing else. PORT, TEST_BASE_URL, GATE_URL and GATE_API_KEY were in the discarded side and are not read. Why it matters that the service exists at all: the e2e test skips itself when DATABASE_URL is unset, and a skip reports as a pass. Demonstrated both ways -- with the database, `flow (db) ... ok` and 8 passed; without it, `flow (db) ... ignored` and the file still exits green having never crossed a stage boundary. A CI that could not run the test would have been indistinguishable from one where it passed. Two incidental fixes needed to get there: - lib/email.ts:283 annotated sendNewsletterConfirmationEmail as returning `SendEmailResult`, a name that does not exist anywhere; the function returns sendEmail(), which is EmailResult, as its three neighbours in the file are already annotated. Pre-existing on main, and the last thing standing between the e2e test and a clean `deno check`. - tests/deliver_bundle_test.ts reformatted to satisfy `deno fmt`, which also reflows the pre-existing out-of-range case the new one was modelled on. deliver.ts and romania-client.ts are added to the type check step for the same reason main.ts is in it: the DeliveryBundle interface omitted keyId while buildBundle returned it, and only a type check could see the two halves of the wire contract disagree. routes/messenger_test.tsx stays OUT of the test step -- it exists on production but not on main, and this branch targets main. All four steps run green locally against a dropped-and-recreated empty database, under `env -i` with only the job env above: Apply migrations 12 applied, exit 0 Format check 13 files, exit 0 Type check exit 0 Test 80 passed, 0 failed, exit 0 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01QktcA31NhygacQTdrnx6B6
PR #111 was CONFLICTING, which is why it had no checks: GitHub cannot build a merge commit for a dirty PR, so it runs no pull_request workflow at all and reports "no checks reported" -- the same silence a broken workflow file produces, from an entirely different cause. main moved by one commit, #106 (the messenger), touching 62 files. Only .github/workflows/ci.yml actually conflicted; lib/questionnaire-session.ts, routes/api/gate-submit.ts, routes/api/auth/magic-link.ts, lib/email.ts and deno.lock all merged clean despite #106 changing createQuestionnaireJWT to require a `via` claim in the same functions this branch rewrote. All four conflict hunks were additive on both sides, so all four keep both: - Zero-logging policy AND Apply migrations. Zero-logging runs first, as on main -- it is a static grep, so a logging regression fails in seconds instead of behind a database bring-up. - main's public/js/ note about seal-guards_test, and this branch's note about why the three tests/ files are named individually. - main's public/js/ and lib/csrf_test.ts test paths, and this branch's three tests/ files. Two-thirds of 933bcb8 turned out to be redundant, which the merge resolves rather than reverts: #106 had already repaired this file's conflict markers (main's copy parses, 95 lines) and had already corrected SendEmailResult in lib/email.ts. What remains unique to this branch is the part #106 had no reason to add -- the Postgres service, the migration step, the DB-backed test paths, and deliver.ts/romania-client.ts in the type check. All six steps run green against a dropped-and-recreated empty database, under `env -i` with only the job env: Zero-logging policy exit 0 Apply migrations 13 applied, exit 0 Format check exit 0 Type check exit 0 Test 110 passed, 0 failed, exit 0 `flow (db) - answers survive a second link and reach the bundle unblanked` runs rather than skipping, which is the whole point of the service.

🛠 Guidelines to remediate hardcoded secrets
- Understand the implications of revoking this secret by investigating where it is used in your code.
- Replace and store your secrets safely. Learn here the best practices.
- Revoke and rotate these secrets.
- If possible, rewrite git history. Rewriting git history is not a trivial act. You might completely break other contributing developers' workflow and you risk accidentally deleting legitimate data.
To avoid such incidents in the future consider
- following these best practices for managing and storing secrets including API keys and other credentials
- install secret detection on pre-commit to catch secret before it leaves your machine and ease remediation.

GitGuardian failed this PR with "1 secret uncovered", and it was right to. 933bcb8 carried four literals into the job env -- JWT_SECRET, RESUME_TOKEN_SECRET, SESSION_SECRET, ENCRYPTION_KEY -- each a plain string assigned to a secret-named key. Nothing in a value like `ci-only-jwt-secret-not-for-production-0` tells a scanner it is a dummy; the name is the signal, and a scanner that ignored it would be the broken one. Calling them "non-secret CI-only dummy values" in a comment reassures a human reader and nothing else. The file already had the right instinct one block earlier, where the Postgres service uses POSTGRES_HOST_AUTH_METHOD: trust with the comment "no password to hardcode (avoids committing a credential-looking literal)". This applies the same reasoning to the rest. JWT_SECRET and RESUME_TOKEN_SECRET are now minted per run with `openssl rand -hex 32` into $GITHUB_ENV. Nothing outside the job needs to know them: tokens are minted and verified inside a single test process, so the values need to exist and hold still for the job, not be reproducible or shared. SESSION_SECRET and ENCRYPTION_KEY are dropped outright rather than generated. Neither is read by any non-test code in the repo -- `grep -rn` over lib/ and routes/ returns 0 references for both. They came from the side this file's earlier conflict discarded, and were carried forward without being checked. Verified with `env -i` carrying only DATABASE_URL, BASE_URL and DENO_ENV plus two freshly generated hex secrets, against a dropped-and-recreated database: Zero-logging policy exit 0 Apply migrations exit 0 Format check exit 0 Type check exit 0 Test 110 passed, 0 failed `flow (db)` still runs rather than skipping. No literal assigned to a key matching SECRET/KEY/TOKEN/PASSWORD remains anywhere in the workflow.

Q2–Q34 posted through a second client that required GATE_API_KEY and copied the gate's response body into Error. The Rust service never reads X-Gate-Key, so an unset key 500'd later answers while the landing form still worked, and a set key checked nothing. Delete that client. Questionnaire answers now use lib/gate_encrypt.ts — loopback, no key, fail closed, body drained not logged. If the gate refuses, /api/questions/answer returns 503 instead of advancing the session as if the plaintext had been stored.

Every second magic link minted a full fresh gate -- token B, keypair, key-box push, fresh_gate_responses row, Q0-Q1 ciphertext -- before createQuestionnaireSession ran. The transaction then re-linked the prior gate row A (correctly: the carried ciphertext is sealed to A's key, and getSessionPubkey resolves one pubkey per session), and everything minted for B was orphaned. The identity sat on the key box until the 30-day shred; the unlinked row, whose encrypted_email stays break-glass-openable, and the Q0-Q1 rows in gate_encrypted_answers -- which the runtime role CANNOT delete, migration 007 grants none -- sat in Postgres forever. The shred design is what decides the shape of the fix. In a system where the runtime deliberately holds no DELETE on ciphertext, write-then-clean-up is not an available strategy; the only winning move is to never write. So provisioning moves INSIDE the session transaction, behind the per-email advisory lock, as a callback createQuestionnaireSession invokes only when planSupersede finds no linked gate row to carry forward: - planSupersede now takes hasFreshGate and answers needsFreshGate, deciding BEFORE any key material exists. A resume with a linked row decides "none", and nothing gate-shaped is ever created to leak. It also no longer needs the key box to be up: the old flow refused a returning respondent with a 503 over a key that would never be used. - lib/gate-provision.ts packages the eager block as buildFreshGateProvisioner, keeping its ordering rules (break-glass first; token into state before the push, so an ambiguous ssh death knows what to shred; the row through the TRANSACTION's client, so rollback reclaims it; the irreversible gate store last) -- now asserted by tests instead of carried as comments. - gate-submit shrinks to: hash, create/resume session (provisioning lazily), link, send. Its catch shreds the pushed identity whenever a token was minted; the rollback handles the rest. The undeletable-ciphertext residue shrinks from every-resume to a commit-failure window. - createQuestionnaireSession accepts a bare token too, unchanged, for the magic-link path linking a row that already exists. The trade accepted: the provisioner does remote I/O (a 20s-deadline push, two 5s gate stores) while the transaction holds a pooled connection and the advisory lock. The lock is scoped to one email hash, so the only contender is the same respondent's second click, and atomicity of row+session is what the transaction buys in exchange. Tests: tests/lazy_gate_provisioning_test.ts -- seven native cases on the provisioner's ordering and failure reporting, four database-backed cases (never-invoked on resume, linked on first walk, rollback of row AND session, magic-link token path), wired into CI's explicit list. The database cases and the previously UNVERIFIED supersede case were run against a real Postgres locally: 122 passed, 0 failed at CI scope; full suite 243 passing (was 203) with the same 45 pre-existing failures.

postgres:15 is a mutable tag. Pin a reviewed SHA-256 digest so later CI runs use the same image until the repository updates the digest.

Do not fall back to session.sessionId for keyId.
Line 236 accepts a nullable gate_token and substitutes the session ID. The renderer then calls loadIdentity with that session ID, but the identity is stored under the gate token. This path fails with ENOENT and prevents PDF delivery.
Require row.gate_token in the existing availability check. Pass row.gate_token directly to buildBundle.

🎯 Functional Correctness | 🔵 Trivial | 🏗️ Heavy lift
Add Deno integration coverage for POST /api/responses/deliver.
tests/deliver_bundle_test.ts calls buildBundle directly, while the endpoint maps row.gate_token to keyId before calling pushBundle. A regression in that mapping can pass the current tests. Add a Deno integration test that exercises the endpoint and asserts distinct sessionId and keyId. The current CI path uses Deno; it does not run Jest.

Update the test-runner instruction in .github/copilot-instructions.md to Deno.
The instruction currently says “Backend: Jest tests in /tests”, but deno.json and CI use deno test. Both cited files use Deno.test and Deno assertions. The current instruction can lead contributors to create tests that CI cannot execute.

Resolve the conflicts that accumulated while this branch sat on an older production tip (#104 messenger, #113 gate-encrypt, audience windows, and the VPN-IP cleanup). Keep both navigation surfaces: people/messages from this branch and the client-side /messenger envelope from production. Take production's messenger.js (the guarded envelope script) and this branch's daily report rewrite. Regenerate fresh.gen.ts so lotto, messenger APIs, _middleware, people, and messages are all in the manifest. Co-authored-by: rbauer <rbauer@colorado.edu>
The production merge added the envelope messenger without the respondent-messaging page. Include both, without duplicating messenger. Co-authored-by: rbauer <rbauer@colorado.edu>

Concurrent visits drop audience counts
Medium Severity
recordVisit mints a new window whenever open is missing or stale, but that check and assignment straddle an await, so two overlapping requests can both mint. The second write to open orphans the first window, and those visitors are never flushed. That undercounts, which is the opposite of the module’s stated bound. persist also replaces the row outright, so two overlapping flushes of the same window can store the smaller snapshot.

Two independent faults, either of which alone meant no PDF, plus the first test in this repo that crosses a stage boundary.
The bug
The site has reported "PDFs returned, all time 0" for its entire life. Every test here was a pure function or a source scan, so no test had ever crossed a stage boundary and nothing could say which of a dozen stages was at fault. It turned out to be two:
1. A second magic link destroyed the work already done.
createQuestionnaireSessionclosed the prior session, minted a new one at question zero in a freshly shuffled order, and left the ciphertext stranded under an id nothing reads —deliver.tsselectsWHERE session_id = $1behind a lookup filteringcompleted_at IS NULL.buildBundlethen backfilled the gaps asskipped: true, so lost answers reached the PDF as blanks indistinguishable from deliberate skips. Both call sites carried the same dead branch, logging "User resuming questionnaire" while doing the opposite.2. The key box could never find an identity.
gate-submitfiles the key under the gate token (pushIdentity(gateToken, …)→<gateToken>.key);render-serviceloaded it bybundle.sessionId, the session HMAC. All 1691 keys on the box are UUID-shaped and not one is 64-hex, soloadIdentityraisedENOENTon every render. That, not the tunnel outage, is why no bundle has ever been decryptable.The fix
session_idis the HMAC of the resume token and the token is never stored, so an issued link cannot be re-derived. Starting over was never required.answered_questionsandcurrent_indexnow carry across, and answers MOVE to the new id: anUPDATE, not a copy — the runtime role holds noDELETEgrant on that table, and a second copy of a respondent's ciphertext contradicts the shred design.getSessionPubkeyresolves exactly one pubkey per session, so carrying ciphertext while linking a newly minted gate row would have turned "answers missing" into "answers present and undecryptable".keyIdbesidesessionId— opened with the first, reported against the second — andvalidateBundlerefuses a traversal-shaped or missing one.planSupersede, a pure function taking the shuffle as a thunk so resuming cannot reshuffle even by accident; reshuffling re-pointscurrent_indexat a different question and files the next answer against one the respondent never saw.Tests
tests/session_supersede_test.ts— 13 unit tests onplanSupersede, where there were none:grep -rn "supersed\|completed_at" tests/was empty.tests/questionnaire_e2e_flow_test.tswalks the whole flow and asserts the seams: that the magic link carries both halves the verifier needs (the JWT it checks and the opaque token whose HMAC is the session id — these fail at different steps with error text that does not distinguish them); that a complete walk yields all 35 answers with none blank; that an interrupted walk is visibly incomplete rather than silently short; that the bundle names the key it must be opened with; that the password option travels sealed ornull, never an empty string that would ask qpdf to encrypt with nothing; and that a respondent twenty questions in who requests another link keeps all twenty.gate-submitgainsbuildMagicLinkUrland amagicLinkForTestingseam so the walk follows exactly the URL a respondent would receive, with nothing posted to a mail server. Email is the only stage not exercised.What is NOT verified
The database-backed case seeds a session, supersedes it, then runs
deliver.ts's own read query against the new id and asserts nothing came back blank — the assertion in the bug's own language. It is guarded onDATABASE_URLand skipped locally: that machine has no Postgres, no psql and no docker. It is written but UNVERIFIED, and needs a CI run or a local database to earn its keep.Suite: 203 passing against main's 180, same 45 pre-existing failures, no new ones. romania: 31 passing, was 29.

Note
High Risk
Changes questionnaire session supersession, encrypted answer migration, gate/key-box provisioning, PDF delivery identity lookup, and trusted client IP resolution—any regression affects respondent data or security controls.
Overview
Questionnaire and PDF delivery are the core of this change. A second magic link no longer wipes progress:
createQuestionnaireSessionusesplanSupersedeand a per-email advisory lock to carry question order, answers, and the linked gate row forward, movinggate_encrypted_answersto the new session id instead of leaving ciphertext behind. Gate provisioning moves inside the transaction viabuildFreshGateProvisioner, so resumes with an existing linked gate row mint no orphan keys or rows. Delivery bundles now includekeyId(gate token) separate fromsessionId, and Romania’s renderer loads identities bykeyIdso PDF generation can succeed.Supporting fixes and infrastructure tighten the path around that flow: unified
gate_encrypt(retiredgate-client), fail-closed 503 on gate store failures,buildBundlenormalises Postgresbigintindices, CI adds Postgres + migrations, ephemeral JWT secrets, and runs DB-backed e2e tests. Proxy trust reads the lastX-Forwarded-Forhop (Caddy-append safe). Mail sends throughsend_mail.pywith PII-safe failure reporting;main.tssuppresses unhandled rejections. Audience counting (lib/audience.ts,_middleware, migration011) persists integer window counts only. Messenger is linked in nav with stronger client-side envelope bounds and tests.Reviewed by Cursor Bugbot for commit f5eb9fb. Bugbot is set up for automated code reviews on this repo. Configure here.
