feat(dashmate): record why certificate renewal failed so doctor can name the cause by shumkov · Pull Request #4476 · dashpay/platform

shumkov · 2026-08-25T00:25:48Z

Issue being fixed or feature implemented

When a scheduled certificate renewal fails, the helper does exactly one thing with the reason:

console.error(`Failed to renew ${providerName} certificate: ${e.message}`);

That line goes to the helper container's stdout and nowhere else. Three consequences:

dashmate doctor cannot name a cause, so it guesses — its remedy for an expired certificate is "Renewal has not succeeded. Check the logs" followed by dashmate logs <cfg> dashmate_helper. dashmate update does the same with "Inbound port 80 is the most common cause." Both hand a non-technical operator a log stream and ask them to interpret it.
Three different situations are indistinguishable: renewal never ran, renewal ran and the authority refused, renewal succeeded but the gateway was never told.
The record is destroyed exactly when it is needed. DASHMATE_HELPER_DOCKER_IMAGE is pinned to the dashmate version, so every version bump changes the image tag and Compose recreates the helper container — a new container starts with an empty log stream. dashmate update is both the command that reports a bad certificate and the command that discards the evidence.

Nothing else can supply this signal. Inbound port 80 is closed on a healthy node except for the seconds a renewal runs, so probing it reports a firewall problem on nodes that are renewing perfectly well — 52 healthy, actively-renewing mainnet nodes looked blocked from outside during the census for #4440. A persisted renewal outcome is the only reliable signal for this failure mode.

Motivation: 25% of mainnet evonodes serve expired certificates (88/353); 91% of that is ZeroSSL's free-tier three-certificate wall.

Builds on #4440 (merged as 482da71304).

What was done?

The helper writes the outcome of each renewal to <config>/platform/gateway/ssl/renewal.json, next to the certificate it describes. Doctor reads it as one more sample and names the cause; update takes the same cause from the same module.

Failures are classified where they happen, because doctor cannot classify what it never sees. ZeroSSL attaches a numeric code to the error it throws; lego prints Let's Encrypt's problem type verbatim as the URN RFC 8555 registers. Neither survives to anything that reads a report later.

Two distinctions this draws that were previously invisible:

A port nothing can reach vs. a port something else is answering on. …error:connection and …error:unauthorized are different problems with different repairs — an operator sent to open an already-open port never finds the web server sitting in front of their node.
A certificate that was issued but never saved. That issuance is spent against a weekly limit whether or not it arrived, so this must never invite another attempt. The fact is sticky until a certificate actually lands, because the failure an hour later carries advice to obtain one.

Every remedy is carried with its cause, so a refused or already-spent issuance cannot end in "ask again". A problem that ends in a runnable command is an instruction to run it, and Let's Encrypt allows only five failed validations per address per hour — shared with the helper's own renewal. On a node whose certificate still works, the message says what to fix and then "dashmate tries again by itself at HH:MM UTC", with no command.

Renewal and gateway reload are separate facts. The success is recorded before the signal is sent; a failed signal is its own field. Folding them together would tell an operator whose certificate renewed minutes ago that renewal had been failing since their previous one. A gateway that is merely stopped records nothing — that is not a certificate problem and is already reported as a stopped service.

Recording can never break a renewal. Classification, redaction and the write sit inside one boundary that swallows its own failures, and the failure write happens after job.stop() — the only thing that arms the hourly retry.

Two guards stop it lying: a failure the installed certificate has outlived is ignored (the helper cannot notice a manual ssl obtain, so the reader has to), and the record is read adjacent to the certificate it describes rather than elsewhere in the collection.

Also included, as the first commit: dashmate doctor --samples <archive> crashed on any archive from a Platform node. The collection date round-trips as a string (date.txt, not .json) and the gateway analyser calls .getTime() on it. Reproduced, fixed test-first, and bisectable on its own. That is the path an operator's report takes to whoever is helping them.

Deliberately not included: no config key, no migration, no notification, no auto-switching provider, no port-80 probe.

How Has This Been Tested?

yarn workspace dashmate mocha 'test/unit/**/*.spec.js' — 730 passing, 0 failing. yarn eslint src test — 0 errors.

Beyond the suite, two things worth calling out:

The operator-facing text was reviewed by rendering it, not by reading the source. That caught defects no amount of code reading would have: the path an operator hits most often (expired certificate, gateway stopped for the documented upgrade) printed the obtain command with the reason it was wrong underneath it, and update printed a cause and then contradicted it.

The new assertions were mutation-tested. scheduleRenewalJob.js had zero coverage — five independent mutations of its ordering guarantees left the suite green, including moving the record write ahead of the job.stop() that arms the retry. Every one of those now fails. The same was done for the retry clock, the provider allow-list, read-side sanitisation, and the three { cause: e } attachments whose removal silently degraded four codes to "could not work out why".

Two hostile-input findings were reproduced and then verified fixed:

A detail field from a third party's archive reached the terminal unfiltered. doctor --samples never passes through the record validator, so ESC[2J could erase the diagnosis and repaint attacker text as dashmate's own output. Stripped at the analyser, where both paths meet.
A quadratic pattern ran on unbounded input: 355 s of event-loop blocking measured on a 1.4 MB Docker error — on the loop that also refreshes the config-lock lease. Now sub-millisecond.

Not tested, and the largest remaining gap: there is no Pebble integration test. The design called one "what makes the Let's Encrypt branch honest". The URN format is verified against lego's source and the connection-vs-unauthorized split against Boulder's documented behaviour, but the Let's Encrypt half of the taxonomy still rests on fixtures written here rather than on real Boulder output. Worth adding before this is relied on.

Breaking Changes

None. No config key, no schema change, no migration — the record is discovered by presence, and its absence is a state the reader handles. Two internal factory signatures gain a homeDir dependency, resolved by name through the existing DI container.

Summary by CodeRabbit

New Features
- Added detailed SSL certificate renewal tracking and failure diagnostics.
- Renewal guidance now identifies provider-specific causes, issuance status, retry conditions, and gateway reload issues.
- Added safer handling for unreadable renewal history and sensitive diagnostic details.
- Prevented outdated renewal attempts from overriding newer certificate or renewal results.
Bug Fixes
- Prevented invalid archived dates from being restored as unusable values.
- Improved certificate issuance error details and troubleshooting guidance.
- Updated certificate troubleshooting links to current documentation.

`dashmate doctor --samples <archive>` crashed on any archive collected from a node with Platform enabled. The collection date is archived as an ISO string and read back verbatim, because the reader parses only `.json` members and the date is stored as `date.txt`. The gateway certificate analyser judges a certificate against the moment the samples were taken rather than the current time - a report is usually opened days after it was collected, and certificates are renewed every few days - so it calls `samples.date.getTime()`, which throws on a string. Optional chaining guarded a missing date but not a wrong type. The archive path is how an operator's report reaches whoever is helping them, so this broke the diagnosis at the point it was needed. An unparseable value is now left unset rather than kept as an Invalid Date, so the comparison falls back to the current time instead of silently yielding NaN. Test would have caught this in CI: ✖ before fix, ✔ after. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Renewal failures are classified into a closed vocabulary, each code carrying one operator-facing sentence and the kind of ending it is allowed to take. Classification happens where the failure happens. Only the helper still holds the provider's account of it: ZeroSSL's numeric code is copied onto the error it throws, and Let's Encrypt's problem type is printed by lego verbatim as the URN RFC 8555 registers. Neither survives to anything that reads a report later, so a reader cannot classify what it never sees. Two distinctions this draws that were previously invisible. A port nothing can reach and a port something else is answering on are different problems with different repairs - an operator sent to open an already-open port never finds the web server sitting in front of their node. And a certificate that was issued but never saved must not invite another attempt, because that issuance is already spent against a weekly limit whether or not dashmate could store it. The three typed lego errors are now carried as the cause of the guidance that replaces them. That guidance is written for a terminal; how far the attempt got - whether the check ever ran, whether an issuance was spent - cannot be recovered by reading it, and an unattended renewal has to record it. What is written down is deliberately narrow: the message only, never the error object. Both providers hang extra fields off what they throw, one of them a task context that on the ZeroSSL path holds the gateway's private key. The excerpt is chosen by allow-list rather than by position, so it cannot become an arbitrary slice of dashmate's own guidance, and the home directory is collapsed before the value is shortened - a cut through an operator's name would defeat the masking a report applies later. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

The helper now writes what happened to a small record beside the certificate, so the reason a renewal failed outlives the container that observed it. Until now the only trace was a line on the helper's stdout. That is lost whenever the container is recreated - which a version bump always does, because the helper image is pinned to the dashmate version - so the evidence disappears during `dashmate update`, the command that tells an operator their certificate is not valid. Nothing else can supply it: inbound port 80 is closed on a healthy node except for the seconds a renewal runs, so probing it reports a firewall problem on nodes that are renewing perfectly well. Three states that were previously indistinguishable are now distinct. Renewal never ran. Both providers can stop before an attempt is ever made - a Let's Encrypt node whose certificate file is gone re-checks hourly for a file that will not appear, and a ZeroSSL node whose account or certificate id is refused does the same. Both are recorded where they happen. Renewal ran and failed. Recorded after the job is stopped, so the write cannot come between a failure and the retry it schedules: that stop is the only thing that arms the next attempt, and skipping it would leave the helper running with nothing scheduled and nothing watching the configuration. Renewal succeeded and the gateway was never told. The certificate is recorded before the signal is sent, and a failed signal is a separate field rather than a failed renewal - otherwise an operator whose certificate renewed minutes ago would be told renewal had been failing since their previous one was issued. A gateway that is simply stopped records nothing: that is not a certificate problem and is already reported as a stopped service. Two facts are kept deliberately sticky. A spent issuance that never landed stays recorded until a certificate actually arrives, because the failure an hour later carries advice to obtain one - which would spend a second certificate against a weekly limit to fix a local problem. And installing a certificate by any route forgets the record entirely, because the helper stops watching configuration while it waits to retry and would otherwise keep reporting a failure the operator has already repaired. Recording can never break a renewal: classification, redaction and the write sit inside one boundary that swallows its own failures, and no caller evaluates anything on the way in.

…ode goes dark Doctor now reads what the helper recorded and names the cause, instead of handing an operator a log stream to interpret. The headline is a problem that did not exist before: a node whose certificate is valid, whose gateway is serving it, and which every other check calls healthy - but whose renewal is failing, so the certificate in use is the last one it will get. On a Let's Encrypt certificate that is about two days of warning. A quarter of mainnet evonodes are already past that point. Where the certificate has already expired, the record replaces the remedy rather than adding a second problem beside it. "Renewal has not succeeded, check the logs" becomes what actually happened. Several things this deliberately does not say. It does not prescribe a command while the node still works: renewal comes back around by itself once the cause is repaired, the authority allows only a handful of failures an hour, and a problem ending in a runnable command is an instruction to run it. It does not say renewal has been failing since it last succeeded - the record knows when renewal last worked and that everything since has failed, not when the failures began, and on a ninety-day certificate those are months apart. It does not show the failure count, which counts scheduler wake-ups rather than attempts. And it says nothing at all when no record exists and the certificate is fine, because a problem with nothing wrong and nothing to do teaches an operator to stop reading them. Two guards keep it from lying. A failure the installed certificate outlives has been overtaken by a repair the helper cannot notice, so it is ignored - without that, an operator who has just fixed port 80 and obtained a certificate is told renewal is failing at the moment they run the command to check their work. And the record is read next to the certificate it describes rather than elsewhere in the collection, because the helper writes both within seconds and the rest of the collection takes long enough to straddle a renewal. Ports are distinguished by where to look: something occupying port 80 on this machine is a different search from something answering upstream, where `ss` lists nothing and the answer is a router or a hosting provider. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

`dashmate update` told operators inbound port 80 was the most common cause and pointed them at the helper's logs. That was honest while nothing recorded what happened - and it is the surface operators actually hit, because updating is a thing they do deliberately and running the doctor is not. Both surfaces now take the cause from one module, so they cannot drift into saying different things about the same failure. The commands around it stay separate, because the doctor renders problems and update renders indented text, and forcing a shared command string is what produced a recurring defect in the work this builds on. The log pointer goes away only when there is something better to say. With no usable record the existing text stands unchanged - including on a node whose record belongs to a previous provider, or whose certificate has already outlived the failure, both of which the shared reader rules out for update exactly as it does for the doctor. Update never renders the excerpt the helper stored. Nothing on this path masks the operator's identity the way a collected report does, so only the cause sentence crosses over. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

…se forbids The remedy was carried with the cause so a refused or already-spent issuance could not end in "ask again" - but only one of the four paths that print an obtain command consulted it, and the three it missed are the ones an operator reaches most often. The commonest report of all - certificate expired, gateway stopped for the documented upgrade - printed one command and the reason it was wrong underneath it. An operator reads until they find something runnable and stops, so the command got run: refused, and one of the few failed validations this node gets per hour spent. That path, the expiry path and `dashmate update` all go through the same remedy classes now, and the cause is printed before the repair rather than after it. A spent issuance is carried forward until a certificate arrives, so it outlives the failure that produced it. It still forbids asking again, but it no longer describes a different failure: a port 80 problem was being answered with "check free space" followed by the obtain command, on the one branch that deliberately prints no command at all. An unread result is not a refusal. It was inheriting the rate-limit wording and telling operators a request "would be refused the same way" directly under a sentence saying dashmate does not know whether anything was requested. A certificate check that could not start is not a firewall problem. It was sending operators to rewrite firewall rules that were never wrong, for a container Docker refused to run. Also: the authority's own words are shown whenever there are any - the field was gated on a code that by construction never has them; the expiring-soon warning no longer tells a node one day from dark that nothing is broken while handing back the command the renewal problem just withheld; a failed reload no longer raises a second problem beside the one that carries the deadline and prescribes the opposite command; ZeroSSL operators are not told their ninety-day certificate renews every few days; an overdue retry names the repair; and the retry time carries a date, because an archived report is read days after it was collected. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

…at held only by reading Found by reviewing the diff rather than the design. The record was cleared after the handover to another provider, not before it. That handover is awaited, and both providers write their first record inside it - so switching provider deleted the incoming provider's record and left a node that renews nothing reporting nothing until its next attempt. An operator following the advice to switch away from an exhausted ZeroSSL account hit this every time, because a failing node reschedules three seconds out and the cron always beats the sixty-second configuration watcher. A cause that established nothing still ended in a request to the certificate authority. The remedy classes exist so a refused or already-spent issuance cannot invite another attempt, but the class for "nothing was established" had no branch and fell through to the obtain command, on a node whose certificate still works. It now sends the evidence to support instead. A certificate file that cannot be read is not the same as one that is absent. The same read throws for a permission denial and for a corrupt certificate, and all three were recorded as missing with the advice to obtain a new one - which spends an issuance against a weekly limit on a problem a new certificate cannot fix. Only an absent file is reported as absent now. Classification ran on the unbounded message rather than the bounded prefix, and one pattern was quadratic: a 1.4 MB Docker error blocked the helper's event loop - the loop that refreshes the configuration lock's lease - for six minutes. Measured before and after: 355 s, now under a millisecond. Terminal escapes in a record could reach a support engineer's terminal. `dashmate doctor --samples` analyses an archive handed over by someone else and never passes it through the reader that validates a local record, so an escape sequence in it could erase the diagnosis printed above and repaint attacker text as dashmate's own output. Stripped at the analyser, where both paths meet; unusable timestamps from the same source no longer crash the diagnosis. The scheduler had no assertion coverage at all. Five independent mutations of its ordering guarantees - including moving the record write ahead of the stop that arms the retry - left the suite green. It now has a spec, and every one of those mutations fails it. Two more that survived elsewhere are pinned too: the retry judged against the reader's clock instead of the sample's, and a provider dashmate does not renew being reported on. So is the cause carried by the three certificate-helper errors, whose removal previously degraded four codes to "could not work out why" in silence. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

…hat the record carries Four smaller findings from the same review. Clearing the record could fail a certificate installation. The delete throws on a permission or busy error, and by the time it runs the pair is on disk and the provider is saved - so a renewal that fully succeeded would have been reported as a failure by the step that only tidies up after it. `update` and the doctor held different definitions of whether a record applies. Both checked the provider and whether the certificate had overtaken the failure, but only the doctor checked whether dashmate renews this node at all. The shared reader exists to make the two provably agree. The certificate authority quotes back what it fetched from port 80, and on the case where something else answered that is arbitrary content from a machine exposed to the internet - a page body, and whatever it happened to contain, copied into a support ticket. The classification sits before that quote, so the echo is dropped. The ZeroSSL key is redacted again on the way into the record. Its own client already redacts before throwing, but by exact substring, so a key echoed back altered would pass straight through. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟠 High · up to fc284

The PR persists renewal outcomes so doctor and update can explain certificate failures, but the current head can lose diagnostic output and can crash, suppress, or overwrite saved renewal state in malformed or concurrent cases. Operators may receive missing or incorrect guidance, so the PR is not merge-ready until these correctness issues are fixed or explicitly accepted.

Included review availability: Your plan provides up to 1 included review per hour; 0 remain after this review.

Review feedback: follow the pattern already used for configuration, and let the record answer questions about itself. The record was a plain object handled by free functions, and both operator surfaces asked the same multi-clause question of it independently - whether the provider still matches, whether the installed certificate has already overtaken the failure. Two copies of one predicate is the drift the shared reader was introduced to prevent, and `update` had already lost a clause the doctor had. `RenewalRecord` now owns those questions - `appliesTo`, `isFailed`, `isIssuanceSpent` - and `RenewalRecordRepository` owns the file: where it lives, reading it into a model, writing one, removing it. Both surfaces ask the model one question and get the same answer by construction. The repository is registered in the container alongside the configuration one, so callers receive it rather than building paths themselves. Validation moves into the model's constructor, which closes a gap the review found: an unparseable certificate start date made the staleness comparison return false and silently suppressed every renewal problem. An archive reaches the analyser without passing through the repository, so treating an unusable date as unknown rather than as older-than-everything is what keeps a malformed report from hiding a real failure. Also from review: the ZeroSSL key is now redacted on the obtain-failure path as well as the read-failure path. That path is the one most likely to have the provider echo the key back, and its excerpt is what reaches a shared report. And an operator-facing correction - "answering on port 80 instead of this node" rather than "answering instead of this node", which read as though the node itself were being replaced.

Preliminary review — Codex only

The renewal persistence model is generally well structured, but three in-scope defects can preserve state across the wrong provider or produce unsafe and incorrect operator guidance. In particular, dashmate update can recommend another issuance after the record explicitly marks an earlier issuance as spent, so changes are required before merge. Source: reviewer backend gpt-5.6-sol; final verifier backend gpt-5.6-sol; orchestration-only (not reviewer evidence): openclaw-agent/cliproxy/gpt-5.6-sol.

Validated blockers were found in the Codex precheck. Opus is deferred until a fresh Codex revalidation clears the blocker gate.

In `packages/dashmate/src/ssl/certificateReporting.js`:
- [BLOCKING] packages/dashmate/src/ssl/certificateReporting.js:79-88: Update drops the sticky spent-issuance guard
  This path reduces the applicable `RenewalRecord` to `{ code }`, discarding `record.isIssuanceSpent()`. If `CERTIFICATE_ISSUED_NOT_SAVED` sets the sticky marker and a later failure records a normally repairable cause such as `PORT_80_UNREACHABLE`, doctor still withholds `ssl obtain`, but update passes only the new code to `renderCertificateGuidance`, which prints the obtain command. That violates the PR's guarantee that a spent issuance remains protected until a certificate lands and makes the two operator surfaces contradict each other. Pass the issuance-spent state into the renderer and make it override the current cause's normal remedy, as the doctor renderer already does.

In `packages/dashmate/src/ssl/renewalFailure.js`:
- [BLOCKING] packages/dashmate/src/ssl/renewalFailure.js:359-364: ZeroSSL reachability failures are classified as a local port conflict
  `Verification server is not responding` is thrown only after `VerificationServer.start()` successfully starts the container with host port 80 bound. The subsequent check fetches the public validation URL, so its failure indicates that the URL was unreachable or did not return a successful response; it cannot mean another local process owns port 80. Returning `PORT_80_IN_USE` sends operators to `ss` to move a nonexistent listener instead of checking the firewall, NAT, forwarding, or public responder.

In `packages/dashmate/src/helper/recordRenewalOutcome.js`:
- [BLOCKING] packages/dashmate/src/helper/recordRenewalOutcome.js:85-91: Failure history is inherited across certificate providers
  `readPrevious` accepts any existing record, even when its provider differs from the provider now recording a failure. A provider change detected by `watchCertificateConfig` stops the old job and hands directly to the new scheduler without clearing the record, so the new provider's first failure inherits the old provider's success timestamp, failure count, and sticky `issuanceSpentAt`. For example, a spent Let's Encrypt issuance can become part of a ZeroSSL record and suppress remediation for an unrelated ZeroSSL failure. Carry prior state only when `previous.getProvider() === provider`.

…e dead links A problem an operator will actually read cannot hold the whole story: three firewall layers, why an external port check reports closed on a healthy node, and which causes must not be retried. The port 80 remedies now carry a link to the guide that does. The doctor's three existing certificate links have been returning 404 since the documentation was reorganised - they point at a path that no longer exists. Repaired against the current location, verified live. The new link is a short redirect rather than a full path, which is the pattern that survived that reorganisation while the full path did not. Requires dashpay/docs#589 to merge and the `evonode-cert-port80` redirect to exist before this ships, or it becomes the fourth dead link.

Docs follow-up

Added a link from the port 80 remedies to a new troubleshooting guide, and repaired three dead links found along the way.

dashpay/docs#589 adds docs/user/masternodes/troubleshooting-certificates.rst. The requirement was documented only as a setup step, and there was no troubleshooting content at all — so the one diagnostic operators reach for first (an external port check) gives a false negative on every healthy node, because nothing listens on port 80 except for the seconds a renewal takes.

Three existing links in analyseConfigFactory.js were returning 404. They point at /en/stable/masternodes/dashmate.html#ssl-certificate, a path that stopped existing when the docs were reorganised. Repaired against the current location and verified live. Unrelated to this feature, but it is the doctor's own SSL guidance and it was already broken.

⚠️ Merge order

The new link uses a short redirect, https://docs.dash.org/evonode-cert-port80 — the pattern that survived the reorganisation that killed the full path above. It does not exist yet:

Merge Add certificate renewal troubleshooting for evonodes docs#589
Create the evonode-cert-port80 redirect (ReadTheDocs admin — I cannot)
Then merge this

Out of order, this ships a fourth dead link. The 404 repairs use verified full paths and have no such dependency.

A ZeroSSL reachability failure was reported as a local port conflict. The verification server had already bound port 80 successfully by the time that error is raised - the check that fails afterwards fetches the node's public validation URL, so nothing local holds the port. Operators were being sent to look for a listener that is not there while the firewall went unexamined. It is an unreachable port, which is the opposite diagnosis. Failure history was inherited across a provider change. The record is cleared when the renewal job itself hands over, but a change picked up by the configuration watcher hands over without clearing - so the new provider's first failure inherited the old provider's last success, its failure count, and its spent issuance. A certificate spent on Let's Encrypt could suppress the repair for an unrelated ZeroSSL failure. Prior state is now carried only when it belongs to the same provider. `update` dropped the sticky spent-issuance guard. It reduced the record to its code alone, so once a later repairable cause replaced the one that spent the issuance, the doctor still withheld the obtain command and update printed it - the two surfaces contradicting each other about a certificate that is spent either way. The flag now travels with the cause and overrides the ordinary remedy on both. Each fix is pinned: reverting it fails its test. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

shumkov · 2026-08-25T03:17:31Z

All three blocking findings confirmed and fixed in 790108f048. Each is pinned by a test — reverting the fix fails it.

ZeroSSL reachability classified as a local port conflict — confirmed. VerificationServer.start() binds port 80 and succeeds before that error is raised, and waitForServerIsResponding() fetches #validationUrl, which is http://${externalIp}/... — the public URL. So the failure cannot mean a local process holds the port. Now PORT_80_UNREACHABLE, which is the opposite diagnosis and the one that sends an operator to the firewall rather than to ss looking for a listener that is not there.

History inherited across a provider change — confirmed, and the asymmetry is exactly as described. The record is cleared when the renewal job hands over, but a change picked up by watchCertificateConfig hands over without clearing. Prior state is now carried only when previous.getProvider() === provider, so a Let's Encrypt issuance can no longer suppress the repair for an unrelated ZeroSSL failure.

update dropped the sticky spent-issuance guard — confirmed, and it defeated the guarantee the PR claims. Reducing the record to { code } meant that once a repairable cause replaced the one that spent the issuance, the doctor withheld ssl obtain and update printed it. The flag now travels with the cause and overrides the ordinary remedy on both surfaces.

Thanks — the second and third are ones the earlier review passes did not reach.

Preliminary review — Codex only

The three prior blocking findings are fixed, and the renewal-record model is generally well structured. Five in-scope blockers remain: two issuance-safety states can be lost, ZeroSSL still conflates unreachable and wrong responders, renewal guidance can omit the required external-IP repair, and hostile archives can retain C1 terminal controls.

In `packages/dashmate/src/listr/tasks/ssl/letsencrypt/obtainLetsEncryptCertificateTaskFactory.js`:
- [BLOCKING] packages/dashmate/src/listr/tasks/ssl/letsencrypt/obtainLetsEncryptCertificateTaskFactory.js:451-466: Actual lego save failures never receive the spent-issuance marker
  The spent-issuance state is set only after lego exits successfully. If the authority issues a certificate but lego then fails to write its artifacts under `/data`, such as because the filesystem is full, lego exits non-zero and this branch throws a generic error before `ctx.certificateObtained` is set or the artifact checks run. The failure consequently becomes `UNKNOWN`, leaves `issuanceSpentAt` unset, and an unusable-certificate diagnosis can recommend another obtain even though the failed run already consumed an issuance. The existing test covers only a successful exit that leaves no files, not the real non-zero save-error path.

In `packages/dashmate/src/helper/recordRenewalOutcome.js`:
- [BLOCKING] packages/dashmate/src/helper/recordRenewalOutcome.js:98-107: An unknown lego result loses its no-retry guard after one more failure
  `RESULT_UNKNOWN` deliberately has a `DO_NOT_RETRY` remedy because the unobserved container may already have obtained a certificate, but the record preserves only confirmed `CERTIFICATE_ISSUED_NOT_SAVED` state across later failures. After an unobserved result is replaced by a repairable failure such as `PORT_80_UNREACHABLE`, no field retains the unresolved issuance uncertainty and both diagnostic surfaces may expose another obtain command. Preserve an unresolved-issuance marker until a certificate lands, while keeping it distinct from `issuanceSpentAt` so the guidance does not claim issuance was confirmed.

In `packages/dashmate/src/ssl/renewalFailure.js`:
- [BLOCKING] packages/dashmate/src/ssl/renewalFailure.js:359-366: ZeroSSL wrong responders are still reported as unreachable
  `VerificationServer.waitForServerIsResponding()` returns the same `false` for a fetch failure and for any non-successful HTTP response. A proxy, router page, or unrelated server returning 403 or 404 therefore produces this exact message and is classified as `PORT_80_UNREACHABLE`, even though something did answer. That sends operators to firewall and NAT-opening guidance instead of the wrong-responder repair the new taxonomy promises. Preserve whether the verification fetch received an HTTP response and classify non-success responses as `PORT_80_WRONG_RESPONDER`, while retaining `PORT_80_UNREACHABLE` for connection failures and timeouts.
- [BLOCKING] packages/dashmate/src/ssl/renewalFailure.js:207: C1 terminal controls survive hostile renewal records
  `doctor --samples` analyzes archives supplied by third parties, and an archive-controlled renewal `detail` is ultimately rendered in the operator's terminal. The sanitizer strips C0 controls and DEL but leaves U+0080 through U+009F intact. Supported terminals can interpret characters such as U+009B as 8-bit CSI and U+009D/U+009C as OSC/ST, allowing hostile archive text to clear or repaint terminal output or attempt clipboard operations. Strip the complete C1 range and add regression coverage using C1 CSI and OSC characters, not only ESC.

In `packages/dashmate/src/doctor/analyse/analyseGatewayCertificateFactory.js`:
- [BLOCKING] packages/dashmate/src/doctor/analyse/analyseGatewayCertificateFactory.js:493-499: Renewal guidance omits the required external-IP prerequisite
  Any applicable failed-renewal record unconditionally replaces the tailored remedy for every installed-certificate reason. `NO_EXTERNAL_IP` can coexist with such a record: after the address is removed, the Let's Encrypt scheduler looks for the new `null.crt` path and records a current missing-file failure. Doctor then omits `dashmate config set ... externalIp` and can recommend `ssl obtain`, even though the obtain task rejects configurations without an external IP. Keep setting the external IP as the first prerequisite, then layer the recorded renewal constraints on top so a spent or uncertain issuance still cannot expose another obtain command.

Review nitpick, taken because the path it covers is the untrusted one. The excerpt was scanned for control characters and then shortened. An archived report is read straight into a sample without passing through the write path that bounds it, so the value can be any length at all - and the scan is what runs first. Bounded in the model instead, which covers the local read and the archive alike rather than the single place the analyser happens to render it.

…uideline Review feedback, accepted over my earlier objection that the surrounding directory is camelCase. The guideline covers the package, and files this change introduces are the ones that can follow it without renaming code the change does not otherwise touch. Class files keep PascalCase. That is a separate and unambiguous convention here - ConfigFile.js, Prescription.js, Samples.js - and the record's model and repository are classes.

Took the two suggestions I had pushed back on.

Kebab-case filenames (ec45fb2598) — applied to the five non-class modules this PR introduces. Class files keep PascalCase, which is a separate and unambiguous convention here (ConfigFile.js, Prescription.js, Samples.js), and the record's model and repository are classes. Pre-existing camelCase files are untouched, so the mixture stays but nothing new adds to it.

Bounded excerpt (38d7418f0f) — fixed in the model rather than at the analyser, so it covers the local read and the archive path alike instead of the one place the analyser happens to render it.

Preliminary review — Codex only

The renewal-record model is well structured, but the exact head still has nine in-scope blockers: all five previously verified findings remain, and four additional paths can discard safety evidence, recommend unsafe issuance, or crash while analyzing an untrusted archive. The new port-80 troubleshooting link also still depends on an unpublished redirect and currently leads operators to a 404.

- [BLOCKING] packages/dashmate/src/listr/tasks/ssl/letsencrypt/obtainLetsEncryptCertificateTaskFactory.js:451-473: Actual lego save failures never receive the spent-issuance marker
  A non-zero lego result is converted to a generic error before `ctx.certificateObtained` is set and before the artifact checks run. Lego can obtain a certificate and then exit non-zero when persisting it under `/data` fails, such as when the mounted filesystem is full. That path is classified as `UNKNOWN`, leaves `issuanceSpentAt` unset, and can expose another obtain command even though the authority already counted the issuance. The existing typed marker covers only a zero exit followed by missing artifacts; preserve a typed post-issuance save failure for the real non-zero path as well.

In `packages/dashmate/src/ssl/certificateReporting.js`:
- [BLOCKING] packages/dashmate/src/ssl/certificateReporting.js:79-92: Unreadable renewal records are treated as if no record exists
  The repository deliberately distinguishes `UNREADABLE` from `ABSENT`, but this reader carries only `PRESENT` records into guidance. The doctor analyzer makes the same reduction for archived samples. A permission failure, malformed JSON, or damaged record can therefore hide a spent or unresolved issuance and restore the ordinary `ssl obtain` recommendation, while neither surface reports that the safety evidence could not be inspected. Handle `UNREADABLE` explicitly and withhold issuance advice until the record is repaired or its state can be established.

In `packages/dashmate/src/ssl/renderCertificateGuidance.js`:
- [BLOCKING] packages/dashmate/src/ssl/renderCertificateGuidance.js:325-334: Support-only renewal failures still prescribe another issuance
  `WITHHOLDS_OBTAIN` includes only `DO_NOT_RETRY`, so `PROVIDER_REJECTED` and `UNKNOWN`, which are classified as `SUPPORT`, fall through to `renderFix()` and print `dashmate ssl obtain`. Doctor has the same result when the installed certificate is unusable: its support-report branch applies only while the certificate remains usable, after which `renderRemedy()` falls through to the generic obtain command. These causes explicitly mean no actionable repair was established, so both surfaces must direct the operator to support without asking the authority again.

In `packages/dashmate/src/doctor/analyse/analyseGatewayCertificateFactory.js`:
- [BLOCKING] packages/dashmate/src/doctor/analyse/analyseGatewayCertificateFactory.js:633-697: Served-certificate findings bypass the renewal no-retry guard
  Only the plain served-expired branch consults `failedRenewal`. When the served and on-disk certificates differ but the saved pair is not a confirmed replacement, lines 633-640 and 665-672 unconditionally print `ssl obtain`; the identity-mismatch and chain-verification remedies likewise bypass the renewal guard. A current `RATE_LIMITED`, `RESULT_UNKNOWN`, or sticky spent-issuance record can therefore produce safe guidance earlier in the report and an opposing runnable command later. Route every certificate-request remedy through the recorded remedy and issuance-state guard.
- [BLOCKING] packages/dashmate/src/doctor/analyse/analyseGatewayCertificateFactory.js:205-216: An extreme archived attempt date crashes doctor
  `RenewalRecord.fromObject()` accepts the maximum valid JavaScript date, `+275760-09-13T00:00:00.000Z`. Adding `RETRY_INTERVAL_MS` exceeds the Date range, and the subsequent `toISOString()` throws `RangeError: Invalid time value`. A third-party diagnostic archive can therefore crash `dashmate doctor --samples` whenever this otherwise valid failed record is rendered for a usable certificate. Validate the derived retry timestamp before constructing or formatting the Date, or reject attempted dates for which the retry instant is out of range.
- [SUGGESTION] packages/dashmate/src/doctor/analyse/analyseGatewayCertificateFactory.js:112: Port-80 guidance links to an unpublished redirect
  The new operator guidance points to `https://docs.dash.org/evonode-cert-port80`, but the redirect is not published and currently returns HTTP 404. The PR discussion explicitly requires the documentation PR and redirect to be published before this code merges. Complete that dependency or use a working maintained URL so the cause-specific port-80 remedies do not send operators to a dead page.
- [BLOCKING] packages/dashmate/src/doctor/analyse/analyseGatewayCertificateFactory.js:482-499: Renewal guidance omits the required external-IP prerequisite
  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3849467311)
  A failed-renewal record completely replaces the tailored `NO_EXTERNAL_IP` remedy, so doctor can omit `dashmate config set ... externalIp` and recommend certificate recovery that cannot work without an address. This state is reachable because the Let's Encrypt scheduler uses the missing address to inspect `null.crt` and records a current missing-file failure. The reciprocal ordering defect exists in `renderCertificateGuidance.js`: its `NO_EXTERNAL_IP` branch prints `ssl obtain` before checking `isIssuanceSpent` or the no-retry remedy. Both surfaces must always retain the external-IP configuration command, then include an obtain command only when the renewal safety state permits it.

In `packages/dashmate/src/helper/record-renewal-outcome.js`:
- [BLOCKING] packages/dashmate/src/helper/record-renewal-outcome.js:98-118: An unknown lego result loses its no-retry guard after one more failure
  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3849467297)
  `RESULT_UNKNOWN` deliberately uses `DO_NOT_RETRY` because the unobserved container may already have obtained a certificate, but only confirmed `CERTIFICATE_ISSUED_NOT_SAVED` state is carried into later records. When the next hourly check replaces `RESULT_UNKNOWN` with a repairable cause such as `CERTIFICATE_FILE_MISSING` or `PORT_80_UNREACHABLE`, no field retains the unresolved issuance uncertainty and both operator surfaces can expose another obtain command. Persist a separate unresolved-issuance marker until a certificate successfully lands, without reusing `issuanceSpentAt`, which would falsely claim issuance was confirmed.

In `packages/dashmate/src/ssl/renewal-failure.js`:
- [BLOCKING] packages/dashmate/src/ssl/renewal-failure.js:359-366: ZeroSSL wrong responders are still reported as unreachable
  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3849467305)
  `VerificationServer.waitForServerIsResponding()` returns the same `false` after connection failures and after receiving any non-success HTTP response. A proxy, router page, or unrelated server returning 403 or 404 therefore reaches this branch and is always classified as `PORT_80_UNREACHABLE`, even though something answered. Preserve whether the verification fetch received an HTTP response and classify non-success responses as `PORT_80_WRONG_RESPONDER`, reserving `PORT_80_UNREACHABLE` for connection failures and timeouts.
- [BLOCKING] packages/dashmate/src/ssl/renewal-failure.js:207: C1 terminal controls survive hostile renewal records
  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3849467314)
  `doctor --samples` renders renewal details from third-party archives in the operator's terminal. The sanitizer strips C0 controls and DEL but leaves U+0080 through U+009F unchanged; U+009B, U+009D, and U+009C survive the current function and can be interpreted as C1 CSI, OSC, and ST by supported terminals. A hostile archive can therefore alter diagnostic output or attempt terminal operations. Strip the complete C1 range and add regression coverage for C1 CSI and OSC/ST input.

…t rewritten A second review pass over the corrected code. Each fix is pinned: reverting it fails its test. **A recorded failure was discarding the one prerequisite that makes guidance runnable.** Replacing a certificate reason's remedy wholesale with the renewal cause dropped the "set this node's address first" step, and the obtain command refuses to start without an address - so a node with no address got advice that cannot be followed. Introduced by the previous commit; the prerequisite now survives whatever the record says. **A cause that established nothing still asked the authority again.** The support ending applied only while the certificate was still usable; once it was broken, both surfaces fell through to the obtain command. "Nothing actionable was established" is not a reason to spend an attempt, whatever state the certificate is in. **An unread result lost its no-retry protection after one more failure.** Only a confirmed spent issuance was carried forward, so an unobserved certificate helper - which may already have been issued a certificate - was protected for exactly one hour, then replaced by an ordinary cause whose advice is to ask again. It is now carried like the confirmed case, and says the different thing it means. **An unreadable record was treated as no record.** The repository distinguishes the two deliberately, and both readers collapsed them - so a permission failure or damaged file silently restored the ordinary obtain advice while hiding the evidence that an issuance was outstanding. Both surfaces now withhold that advice and say the record could not be read. **A ZeroSSL check failure claimed more than it observed.** The previous commit corrected it from "port occupied" to "port unreachable", which is the same error in the other direction: the check answers identically when nothing replied and when a proxy replied with the wrong status. It now reports what was actually established - the node's address did not answer dashmate's own check - and the remedy covers both readings. **An archived date could crash the doctor.** A date near the edge of the representable range is valid on its own, and the retry instant derived from it overflows; formatting that threw out of the entire diagnosis. Rejected where it enters, so one bad field costs one record rather than the whole report. **Eight-bit control codes survived sanitising.** A terminal in 8-bit mode reads U+009B as a control sequence introducer without the escape that precedes it in the 7-bit form, so stripping only C0 and DEL left the channel open on the untrusted archive path.

All seven confirmed and fixed in 77fd674fae. Each is pinned — reverting it fails its test. Two I verified by execution rather than reading, because both looked unlikely: the extreme archived date does throw RangeError out of the analyser, and U+009B does survive the sanitiser.

The address prerequisite — my regression, from the commit that routed every certificate reason through the renewal cause. It replaced the remedy wholesale, prerequisite included, leaving guidance that cannot run at all since obtain refuses to start without an address. The prerequisite now survives whatever the record says.

Support-only causes still prescribing an issuance — correct on both surfaces. My support ending was gated on the certificate still being usable, so once it was broken both fell through to obtain. "Nothing was established" is not a reason to spend an attempt in either state.

Unread result losing its guard — correct, and the same shape as the spent-issuance bug fixed earlier. Only the confirmed case was carried forward, so RESULT_UNKNOWN was protected for exactly one hour. Now carried as its own marker, with wording that says the different thing it means.

Unreadable treated as absent — correct, and it defeated the point of distinguishing them. Both surfaces now withhold issuance advice and say the record could not be read.

ZeroSSL wrong responders — you are right, and this is my previous fix over-corrected. I changed it from "occupied" to "unreachable" when waitForServerIsResponding returns the same false for a fetch failure and for a non-ok status. Both were claims the evidence does not support. It now reports what was actually established — the address did not answer dashmate's own check — with a remedy covering both readings.

Extreme archived date — reproduced. Rejected where it enters, so one bad field costs one record rather than the whole report.

C1 controls — reproduced. Now stripped through U+009F.

742 passing, 0 lint errors.

Worth noting for whoever reviews this: four of the seven were in guidance I had rewritten one commit earlier in response to review. The rate of real findings is not yet falling, and the Pebble integration test is still absent — the ZeroSSL misclassification is exactly what a real ACME run would have caught.

Preliminary review — Codex only

The persisted renewal model is generally well structured, and the targeted renewal suite passes with 195 tests. Eight in-scope findings remain: seven blockers can lose issuance evidence, bypass no-retry safeguards, or provide materially incorrect diagnostics, and the new troubleshooting URL still returns HTTP 404.
Source: Codex reviewer backend gpt-5.6-sol; final verifier backend gpt-5.6-sol; openclaw-agent/cliproxy/gpt-5.6-sol is orchestration-only and not reviewer evidence.

Validated blockers were found in the Codex precheck. Opus is deferred until a fresh Codex revalidation clears the blocker gate.

- [BLOCKING] packages/dashmate/src/listr/tasks/ssl/letsencrypt/obtainLetsEncryptCertificateTaskFactory.js:451-473: Actual lego save failures never receive the spent-issuance marker
  A non-zero lego result is converted to a generic `Error` before `ctx.certificateObtained` is set or artifact checks can raise `LegoArtifactsMissingError`. This is a real post-issuance path: lego v4.31.0 calls `Certificate.Obtain()` and only afterward calls `CertificatesStorage.SaveResource()`, whose write failures terminate lego with a non-zero exit. A full filesystem or permission failure after issuance is therefore recorded as `UNKNOWN`, leaves `issuanceSpentAt` unset, and can expose another obtain command even though the authority already counted the issuance. Preserve a typed post-issuance save failure for lego's non-zero save-error output, not only for a zero exit followed by missing artifacts.

In `packages/dashmate/src/ssl/renderCertificateGuidance.js`:
- [BLOCKING] packages/dashmate/src/ssl/renderCertificateGuidance.js:344-351: Renewal guidance omits the required external-IP prerequisite
  Doctor now retains the external-IP prerequisite, but update's reciprocal path remains unsafe. The `NO_EXTERNAL_IP` branch runs before the unreadable-record and renewal no-retry guards, and `renderNoExternalIpGuidance()` always includes `dashmate ssl obtain`. A node with no external address plus a current rate limit, spent or uncertain issuance, support-only failure, or unreadable record is therefore told to request another certificate even though the same renewal state suppresses that command for every other certificate reason. Always render the external-IP configuration command first, then include the obtain command only when the renewal safety state permits it.
- [BLOCKING] packages/dashmate/src/ssl/renderCertificateGuidance.js:212-223: Update reports an uncertain issuance as confirmed and unsaved
  `isIssuanceOutstanding` is true for both a confirmed `issuanceSpentAt` and an uncertain `issuanceUncertainAt`, but this branch renders both as “A certificate was issued and could not be saved” and directs the operator to storage space and permissions. For an unobserved lego result, neither issuance nor a save failure was established; doctor correctly describes that state as a certificate that may have been issued. Pass the uncertainty state separately and render its distinct explanation here.

In `packages/dashmate/src/doctor/analyse/analyseGatewayCertificateFactory.js`:
- [BLOCKING] packages/dashmate/src/doctor/analyse/analyseGatewayCertificateFactory.js:402-420: Unreadable renewal records are treated as if no record exists
  The update reporter now handles `UNREADABLE`, but doctor still creates a renewal record only for a valid `PRESENT` sample. An `UNREADABLE` sample—or a `PRESENT` archived object that `RenewalRecord.fromObject()` cannot reconstruct—is reduced to `null`, so invalid and expired certificate paths restore the ordinary `ssl obtain` remedies. The unreadable evidence may contain a spent or uncertain issuance marker. Preserve this state explicitly, report that the renewal evidence could not be inspected, and withhold certificate-request advice until it can be established safely.
- [BLOCKING] packages/dashmate/src/doctor/analyse/analyseGatewayCertificateFactory.js:655-719: Served-certificate findings bypass the renewal no-retry guard
  The served/on-disk mismatch branches still print `dashmate ssl obtain` unconditionally, as do the conditional identity-mismatch and chain-verification remedies. These findings can be emitted alongside the renewal-aware installed-certificate finding, so a current `RATE_LIMITED`, `RESULT_UNKNOWN`, unreadable record, or sticky issuance marker can produce safe guidance earlier in the report and an opposing runnable command afterward. Route every remedy that requests a certificate through the same renewal-state and unreadable-record guard used by `renderRenewalCause()`.
- [SUGGESTION] packages/dashmate/src/doctor/analyse/analyseGatewayCertificateFactory.js:112: Port-80 guidance links to an unpublished redirect
  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3850840312)
  The new operator guidance points to `https://docs.dash.org/evonode-cert-port80`, which still returns HTTP 404 at the exact head. The PR discussion also records the required merge order: publish the documentation and create the ReadTheDocs redirect before merging this code. Publish that redirect first or use a currently working maintained URL so every cause-specific port-80 remedy does not send operators to a dead page.

In `packages/dashmate/src/ssl/renewal-failure.js`:
- [BLOCKING] packages/dashmate/src/ssl/renewal-failure.js:342-384: Locally rejected ZeroSSL keys are classified as unknown
  `PROVIDER_AUTH` is selected only when ZeroSSL returns one of the recognized numeric codes. `requestApi.createHeaders()` can instead reject a null, empty, whitespace-padded, or otherwise unusable configured key locally with `Error('Invalid ZeroSSL API key')`; that error has no numeric `code` and falls through to `UNKNOWN`. This is reachable because the configuration schema permits a null key, and the ZeroSSL scheduler calls `getCertificate()` directly before the validation path that reports a missing key. Recognize the client's local invalid-key error as `PROVIDER_AUTH` so operators receive the known account repair instead of support-only guidance.
- [BLOCKING] packages/dashmate/src/ssl/renewal-failure.js:368-376: ZeroSSL wrong responders are still reported as unreachable
  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3849467305)
  `VerificationServer.waitForServerIsResponding()` still returns the same `false` after a connection failure and after receiving a non-success HTTP response. The new `PORT_80_CHECK_FAILED` label avoids making an unsupported classification, but `renderPortEightyHint()` sends that generic code through its firewall/NAT-opening fallback. A proxy, router page, or unrelated server returning 403/404 therefore still receives unreachable-only repair advice. Preserve whether an HTTP response was received and use `PORT_80_WRONG_RESPONDER`, or make the generic remedy explicitly cover both responder and reachability cases.

…tificate Review found that the shared derivation was authoritative only where the renewal record was being read. Eight other branches - a trust failure, an address mismatch, an expiring warning, a served certificate that differs from disk - printed the obtain command directly, having never heard of the renewal record. So a node with an issuance already spent and unsaved could still be told to ask for another one, by whichever branch happened to fire. Every branch that would request a certificate now goes through one gate that reads the derivation, and returns either the command or the reason it is being withheld. Deciding it per branch is what allowed the contradiction, and adding the derivation without removing those decisions only narrowed it. Pinned by a test that asserts a trust failure - a branch with no connection to renewal at all - withholds the request while an issuance is outstanding.

… make the fence atomic Review of the previous round. Three blocking, and the first two were introduced by the fix before them. **The shared decision could not decide.** It was derived without knowing whether the node still had a working certificate - and that is exactly what decides whether waiting for the next automatic attempt is affordable or is a live outage. So each surface reapplied usability locally, and they diverged again: with an expired certificate and a port 80 failure, the doctor said obtain and update said repair and wait, for the same node in the same state. The derivation now takes usability and returns one of two distinct actions, and neither renderer decides it any more. **A request escaped the gate.** The address prerequisite always printed an obtain command of its own, so a node with no address and an issuance already spent was told to set the address and then ask for another certificate - beside the warning saying not to. The prerequisite keeps its text; the request it used to carry goes through the same decision as every other one. **The fence was not atomic, and a review ruled that a blocker rather than the residual I had argued for.** It was right: a superseded holder can read the high-water mark, be descheduled, and write after a newer chain has already written; two processes can read the same number and both claim it. The configuration lock does not cover this, because a renewal releases it before its bookkeeping runs. Claim, write and remove now hold an exclusive fence. That fence is a plain exclusive create rather than the lock library used for configuration. This runs on the helper's only thread, inside a cron callback, and under tests that replace the global timers - a fence that needs a timer to stay alive can fail for reasons having nothing to do with renewal, and the library's synchronous path took one. Its cross-process behaviour is not proven by these tests. A single process cannot demonstrate it, and a test asserting the lock file appears would be a snapshot of the implementation rather than of the guarantee. Said here rather than papered over. Also: malformed fence content now refuses rather than reading as no fence at all; ZeroSSL 2839 no longer renders as the three-certificate wall on update; 2841 no longer asserts an account problem, because the provider reuses that number for a CAA failure on another endpoint and the number alone does not establish which; and the rate-limit wording names the account as well as the address, since the limit counts both.

Preliminary review — Codex only

The targeted renewal diagnostics suite passes with 189 tests, and several prior safety defects are fixed, but nine blocking issues remain. The most consequential paths can lose or bypass outstanding-issuance evidence, issue duplicate generation claims, or present operator commands that contradict the shared no-obtain decision; the new documentation link also remains unpublished. Source: Codex reviewers gpt-5.6-sol (general and security-auditor); final verifier gpt-5.6-sol; openclaw-agent/cliproxy/gpt-5.6-sol is orchestration-only and not reviewer evidence.

Validated blockers were found in the Codex precheck. Opus is deferred until a fresh Codex revalidation clears the blocker gate.

- [BLOCKING] packages/dashmate/src/listr/tasks/ssl/letsencrypt/obtainLetsEncryptCertificateTaskFactory.js:451-466: Actual lego save failures never receive the spent-issuance marker
  Every non-zero lego result is converted to a generic `Error` before `ctx.certificateObtained` is set and before the artifact checks can raise `LegoArtifactsMissingError`. Lego obtains the certificate before calling its certificate storage `SaveResource` path, so a full filesystem or permission failure while saving exits through this branch after the authority counted the issuance. The resulting untyped failure does not set the sticky `issuanceSpentAt` marker; although an immediate `UNKNOWN` diagnosis withholds another request, a later repairable failure can overwrite it and expose `ssl obtain`. Preserve a typed post-issuance persistence failure when lego's output identifies its save step, rather than covering only a zero exit followed by missing files.

- [BLOCKING] packages/dashmate/src/doctor/analyse/analyseGatewayCertificateFactory.js:295-304: The spent-issuance branch bypasses the shared no-obtain decision
  `deriveRenewalGuidance()` returns `DO_NOT_OBTAIN` for a spent issuance, and `renderRemedy()` computes `mayObtain` from that decision. The `CERTIFICATE_ISSUED_NOT_SAVED` branch nevertheless ignores `mayObtain` and appends the runnable `ssl obtain` command immediately after warning that another request would spend another issuance. Remove the request from this branch and direct the operator to inspect or repair storage without asking the authority again while the sticky marker remains.
- [BLOCKING] packages/dashmate/src/doctor/analyse/analyseGatewayCertificateFactory.js:462-491: Unreadable renewal records are treated as if no record exists
  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3852942100)
  An explicit `UNREADABLE` sample is handled conservatively, but a sample marked `PRESENT` that `RenewalRecord.fromObject()` cannot reconstruct is reduced to `null`. `isRecordUnreadable` checks only the original `UNREADABLE` state, so the shared derivation receives neither a record nor an unreadable flag and returns `SAFE_ACTION.OBTAIN`. A malformed, damaged, future-format, or hostile archived object can therefore erase a spent or uncertain issuance guard. Treat `PRESENT` plus failed reconstruction as unreadable and withhold certificate requests.
- [SUGGESTION] packages/dashmate/src/doctor/analyse/analyseGatewayCertificateFactory.js:118: Port-80 guidance links to an unpublished redirect
  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3850840312)
  The new cause-specific remedies point to `https://docs.dash.org/evonode-cert-port80`, but the supplied PR evidence records that this redirect returns HTTP 404 and must be created after the corresponding documentation PR is published. Publish that dependency before merging this code or use an already maintained working URL so the operator guidance does not lead to a dead page.

In `packages/dashmate/src/ssl/renewalRecord/RenewalRecordRepository.js`:
- [BLOCKING] packages/dashmate/src/ssl/renewalRecord/RenewalRecordRepository.js:82-88: First-use initialization happens outside the generation fence
  The generation file's existence check and initial zero write happen before the exclusive lock is acquired. On first use, two processes can both observe the file as absent; one can initialize and claim generation 1, after which the other's already-authorized zero write resets the high-water mark and lets it claim generation 1 as well. Both scheduling chains then pass the current-generation check. Acquire the lock before checking or initializing the generation file so initialization and increment are one critical section.
- [BLOCKING] packages/dashmate/src/ssl/renewalRecord/RenewalRecordRepository.js:121-140: A stale-lock takeover lets the old owner release the new owner's fence
  The lock contains no ownership token, yet a contender removes it after a fixed ten-second mtime threshold and every holder later releases it with an unconditional `rmSync`. If the original process pauses after reading the generation, a replacement can break the lock and update the generation; the original can then resume and write its stale value. If it resumes while the replacement still holds the recreated lock, its release can also delete the replacement's fence and admit a third process. Use ownership-aware locking and reject mutation after ownership is lost, or avoid reclaiming a lock solely because an unrefreshed mtime crossed a fixed threshold.

In `packages/dashmate/src/doctor/analyse/analyseConfigFactory.js`:
- [BLOCKING] packages/dashmate/src/doctor/analyse/analyseConfigFactory.js:125-193: Legacy SSL findings still prescribe requests forbidden by the renewal record
  `analyseSamplesFactory` runs this legacy SSL analyser before the new renewal-aware gateway analyser, but the ZeroSSL and Let's Encrypt remedies here still print `dashmate ssl obtain` or `--force` without consulting the shared decision. A node with a current rate limit, quota exhaustion, support-only failure, unreadable record, or outstanding issuance can therefore receive safe no-obtain guidance from the gateway analyser and an opposing runnable command from `CERTIFICATE_EXPIRES_SOON`, `CERTIFICATE_IS_NOT_VALID`, `ZERO_SSL_API_ERROR`, or the corresponding Let's Encrypt findings. Every doctor remedy that requests a certificate must consume the same derived renewal decision, or these duplicate legacy findings must be suppressed when the gateway analyser owns the certificate diagnosis.

In `packages/dashmate/src/helper/record-renewal-outcome.js`:
- [BLOCKING] packages/dashmate/src/helper/record-renewal-outcome.js:31-35: A corrupt prior record loses its sticky issuance guard on the next failure
  `readPrevious()` maps every state other than `PRESENT` to `null`. For malformed JSON or an invalid record shape, the next scheduled failure therefore writes a fresh record without either issuance marker; the existing test explicitly expects corrupt history to be replaced. Doctor is conservative only until that write occurs, after which a repairable failure can restore an obtain command even though the discarded record may have contained spent or uncertain issuance evidence. Preserve uncertainty when a prior record exists but is unreadable, or refuse to replace it with a record that asserts no issuance is outstanding until a certificate successfully lands.

In `packages/dashmate/src/ssl/renewal-failure.js`:
- [BLOCKING] packages/dashmate/src/ssl/renewal-failure.js:404-413: ZeroSSL wrong responders are still reported as unreachable
  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3849467305)
  `VerificationServer.waitForServerIsResponding()` returns the same `false` for connection failures and non-successful HTTP responses. This classifier records the neutral `PORT_80_CHECK_FAILED`, but `renderPortEightyHint()` routes that code through its default firewall, NAT, and port-opening remedy. A proxy, router page, or unrelated server returning 403 or 404 therefore still receives unreachable-only guidance even though port 80 answered. Preserve whether an HTTP response was received and classify it as `PORT_80_WRONG_RESPONDER`, or make the generic remedy explicitly cover both reachability and wrong-responder states.
- [BLOCKING] packages/dashmate/src/ssl/renewal-failure.js:415-420: Locally rejected ZeroSSL keys are classified as unknown
  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3852942121)
  `requestApi.createHeaders()` throws `Error('Invalid ZeroSSL API key')` for null, empty, whitespace-padded, or otherwise unusable keys. That error has no numeric provider code and matches neither provider-unreachable string here, so it falls through to `UNKNOWN`. This is reachable because the configuration can contain a null key and the scheduled ZeroSSL path calls the API client directly. Classify this known local client error as `PROVIDER_AUTH` so the operator receives the account-credential repair instead of support-only guidance.

…enewal A scheduled renewal records why it failed so the doctor can name the cause instead of guessing. Two defects meant it regularly recorded the wrong cause, or none at all, and neither was visible without a real ACME server. The lego container is started with AutoRemove, so the daemon deletes it - and its output with it - the moment it exits. The output was read after wait() returned, inside a catch with an empty body, making it a race the daemon usually won: the authority's account of the failure was absent from all eight measured runs, leaving an exit code from which every cause looks alike. It is now attached while the container still runs, and demultiplexed - Docker's frame headers were landing in the middle of the text an operator reads and of the reason stored for support. With the output present, the classifier read the first ACME problem type in it rather than the one that ended the run. A rejected nonce is retried and survived - RFC 8555 requires the retry, and authorities issue them routinely - so it appears before the real failure and won: a genuine port 80 fault was reported as a bare provider refusal in two of eight runs. The terminal problem is taken now, and the quoted evidence with it, so a record cannot cite a line that disagrees with its own verdict. Reading from the end also means the length cap must not sever the type it is about to read, so it cuts back to a line break. Tests: a new Pebble case breaks validation the two ways a node breaks it - nothing answering on port 80, and something answering that is not this node - and drives the real error through the classifier and the record. 0 of 8 runs passed before these fixes and 8 of 8 after, with the nonce case exercised in five of them. Because that case only appears about half the time, three unit tests pin the same behaviour deterministically; each was checked by mutation. The cross-process behaviour of the log attach is not proven by these tests - a single process cannot demonstrate it, and asserting the call order only restates the implementation. What is pinned is that the attach happens before the container can exit. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Preliminary review — Codex only

The exact head still has ten in-scope blockers: nine previously verified renewal-safety defects remain, and the latest output collector still attaches only after an auto-removed lego container has started, so fast failures can lose the evidence this PR is intended to persist. The external port-80 documentation redirect remains intentionally deferred under the PR's stated merge-order requirement; one additional lower-severity timer cleanup was omitted because of the 10-finding budget.
Source: reviewer backends gpt-5.6-sol (general and security-auditor); final verifier backend gpt-5.6-sol. Orchestration-only, not reviewer evidence: openclaw-agent/cliproxy/gpt-5.6-sol.

Validated blockers were found in the Codex precheck. Opus is deferred until a fresh Codex revalidation clears the blocker gate.

- [BLOCKING] packages/dashmate/src/listr/tasks/ssl/letsencrypt/obtainLetsEncryptCertificateTaskFactory.js:527-539: Actual lego save failures never receive the spent-issuance marker
  Every non-zero lego exit is still converted to a generic `Error` before `ctx.certificateObtained` is set and before the artifact checks can raise `LegoArtifactsMissingError`. Lego can obtain a certificate and then exit non-zero when its later persistence under `/data` fails, so that path consumes an issuance but is recorded as `UNKNOWN` without `issuanceSpentAt`. Although the immediate unknown diagnosis withholds another request, a later repairable failure can overwrite it and expose `ssl obtain`; recognize lego's post-issuance save-error output and preserve it as a typed spent-issuance failure.
- [BLOCKING] packages/dashmate/src/listr/tasks/ssl/letsencrypt/obtainLetsEncryptCertificateTaskFactory.js:492-513: Auto-remove can still delete lego output before attachment
  `startLegoContainer()` awaits `container.start()` and returns only afterward; `collectContainerOutput()` is then called on the returned container. With `AutoRemove: true`, a fast-failing lego process can exit and be removed between the completed start request and the subsequent `logs({ follow: true })` request. Awaiting the logs promise before `wait()` would narrow a second race but would not close this earlier one. Attach stdout and stderr after creation but before starting the container, or disable auto-removal and remove the container only after its output has drained.

- [BLOCKING] packages/dashmate/src/doctor/analyse/analyseConfigFactory.js:95-195: Legacy SSL findings still prescribe requests forbidden by the renewal record
  `analyseSamplesFactory` still runs this legacy SSL analyzer before the renewal-aware gateway analyzer, and these ZeroSSL and Let's Encrypt remedies directly print `dashmate ssl obtain` or `--force` without consulting the shared renewal decision. A rate limit, quota exhaustion, support-only failure, unreadable record, or outstanding issuance can therefore produce conservative guidance from the new analyzer and an opposing runnable command from this one. Route every certificate-request remedy through the shared decision, or suppress these duplicate legacy SSL findings when the gateway analyzer owns the diagnosis.

  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3849467305)
  `VerificationServer.waitForServerIsResponding()` returns the same failure for a connection error and for a non-successful HTTP response. This classifier records the neutral `PORT_80_CHECK_FAILED`, but `renderPortEightyHint()` routes that code to firewall, hosting-provider, and port-opening instructions. A proxy, router page, or unrelated server returning 403 or 404 therefore receives an unreachable-port repair even though something answered. Preserve whether an HTTP response was received, or make the generic remedy explicitly cover both reachability and wrong-responder states.
- [BLOCKING] packages/dashmate/src/ssl/renewal-failure.js:443-448: Locally rejected ZeroSSL keys are classified as unknown
  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3852942121)
  `requestApi.createHeaders()` throws `Error('Invalid ZeroSSL API key')` for null, empty, whitespace-padded, or otherwise unusable keys. That local error has no numeric provider code and matches neither provider-unreachable message here, so it falls through to `UNKNOWN`. The scheduled ZeroSSL path passes the non-required configuration value directly to the API client, making this reachable when the configured key is null. Recognize the exact local client error as `PROVIDER_AUTH` so the operator receives the account-credential repair instead of support-only guidance.

  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3852942100)
  An explicit `UNREADABLE` sample is handled conservatively, but a sample marked `PRESENT` for which `RenewalRecord.fromObject()` returns `null` is not. In that case `renewalRecord` and `failedRenewal` are null while `isRecordUnreadable` remains false, so the shared derivation returns `SAFE_ACTION.OBTAIN`. A malformed, damaged, future-format, or hostile archived object can therefore erase a spent or uncertain issuance guard. Treat `PRESENT` plus failed reconstruction as unreadable and withhold certificate requests.
- [BLOCKING] packages/dashmate/src/doctor/analyse/analyseGatewayCertificateFactory.js:295-304: The spent-issuance branch bypasses the shared no-obtain decision
  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3854667831)
  `deriveRenewalGuidance()` returns `DO_NOT_OBTAIN` for a spent issuance, and `renderRemedy()` computes `mayObtain` from that decision. The `CERTIFICATE_ISSUED_NOT_SAVED` branch nevertheless ignores `mayObtain` and appends the runnable `ssl obtain` command immediately after warning that another request spends another issuance. Remove the request from this branch and direct the operator to inspect or repair storage without prescribing another authority request while the sticky marker remains.

  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3854667843)
  The generation file's existence check and initial zero write still happen before the exclusive lock is acquired. Two first-use processes can both observe the file as absent; after one initializes and claims generation 1, the other's already-authorized zero write can reset the high-water mark and let it claim generation 1 as well. Both scheduling chains can then pass the current-generation check. Acquire an independently creatable lock before checking or initializing the generation file so initialization and increment form one critical section.
- [BLOCKING] packages/dashmate/src/ssl/renewalRecord/RenewalRecordRepository.js:119-145: A stale-lock takeover lets the old owner release the new owner's fence
  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3854667853)
  The recreated lock has no ownership token. A contender removes it solely because its mtime is more than ten seconds old, while every holder's release callback unconditionally removes the current lock path. If the original holder is suspended, a replacement can break the lock and enter its mutation; when the original resumes, it can still perform its stale mutation and delete the replacement's fence, admitting another writer. Use ownership-aware locking that verifies ownership before mutation and release, or do not reclaim a lock solely from this fixed, unrefreshed mtime threshold.

In `packages/dashmate/src/helper/record-renewal-outcome.js`:
- [BLOCKING] packages/dashmate/src/helper/record-renewal-outcome.js:31-35: A corrupt prior record loses its sticky issuance guard on the next failure
  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3854667857)
  `readPrevious()` maps every state other than `PRESENT` to `null`. If the previous file is malformed or unreadable, the next scheduled failure replaces it with a fresh record carrying neither issuance marker. Doctor is conservative only until that write; a later repairable failure can then expose `ssl obtain` even though the discarded record may have contained a spent or uncertain issuance. Preserve uncertainty when prior state exists but cannot be read, or refuse to replace it with a record asserting that no issuance is outstanding until a certificate successfully lands.

…xt move The recorded cause drives what `dashmate doctor` and `dashmate update` tell an operator to do. Certificate authorities quote whatever answered on port 80 back into their problem detail, so that text is partly written by the machine being diagnosed - and it was reaching the decision. Reading a cause and choosing an action are now separate. A cause read from a message may name anything and give any local instruction; it may never reach a provider switch, a wait, or a refusal to obtain. Those come only from typed errors and from the provider's own numeric codes, neither of which is text. That separation is what removes the parser. Earlier attempts tried to make the reading certain enough to justify the action - an anchored lego envelope, a wrapper-chain grammar, a trusted prefix - and each one was defeated by the next shape lego or its dependencies emit. None of it is needed once confusing one port-80 cause for another cannot change what anybody is told to do. The scan is a plain one with a priority order, and port 80 outranks a rate limit: naming a rate limit while a firewall is shut leaves the node dark, while naming port 80 during a real rate limit costs a few minutes. Five signals were recognised by searching the whole message for a phrase, or by an unqualified `code` property - the configuration lock, the ZeroSSL preflight, a malformed provider response, a transport failure, and a missing certificate file. Every one of them ends in advice to stop and wait, and every one could be triggered by a page served back to the certificate check. All five are raised by this repository, so each is now a typed error thrown where the failure happens, and the substring branches are deleted. `ENOENT` in particular is decided at the one place that knows the read was local: the same read fails for a permission denial and a corrupt file, and neither is repaired by a new certificate. The provider now reaches classification, which it never did. Its numeric code is read before any message, so a spent ZeroSSL free tier is no longer reported as a rate limit that clears on its own. It does not clear - the remedy is a different provider, and that path is the most common reason a mainnet certificate expires. Doctor also offers the check that tells an operator whether their repair worked, instead of sending them away for an hour. There is no other way to find out: nothing listens on port 80 outside a renewal, which is why an external port scan reads closed on a healthy node. A failed check spends one of five hourly validations; the allowance worth protecting is the weekly one, and only an outstanding issuance or a spent provider quota can waste that. The troubleshooting guide link pointed at a short path that was never created and answered 404. It now uses the published article. Tests: the action a message may produce is pinned as one invariant over the whole set rather than case by case - a per-case list is what let a rate limit quietly choose "wait" and an unfamiliar problem type quietly choose "support". Six mutations were checked, and one survived at first: the numeric-before-message ordering was only passing because the provider gate protected it, so a case that exercises the gate open was added and the mutation now fails. The Pebble tests still pass against a real ACME server. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

The renewal record withholds the obtain command when an issuance is already outstanding, and that marker does not exist for the case it was written for. When the certificate helper obtains a certificate and then fails to save it, it exits non-zero, and dashmate only records that an issuance happened on a clean exit. Nothing marks the allowance as spent. A later port-80 failure overwrites the record, and the operator who repairs port 80 and asks again spends a second certificate from a weekly handful into the same broken storage. Nothing local distinguishes "issued, then could not be saved" from "never issued" - the difference lives only in text that is partly written by whatever answered on port 80. So the precondition is asked directly instead of inferred: at the moment a renewal fails, on the machine that would have to save the certificate, can these directories be written? The answer travels in the record, because the doctor reads archives collected on other machines and cannot look for itself. Three states, not two: a record written before this existed carries nothing, and is not read as an assurance it never gave. The probe is a real write rather than a permission bit. The fault that matters passes every access check: a full disk is writable by mode and refuses the write. `dashmate update`'s interactive prompt now reads that record before offering anything. It defaults to Yes and obtains directly, and it previously ran without consulting the helper's history at all - its own header said so - so the guarantee enforced on every other surface could be walked straight past. A guarantee enforced in three places and bypassed in a fourth is not a guarantee. Tests: the withholding is asserted across an outstanding issuance, an uncertain one and unwritable storage, and separately that a request is never offered while storage refuses - including through the provider switch, which still has to save what it obtains. Three mutations checked: dropping the precondition, a probe that reports success on a directory that refused, and removing the update gate. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Six defects in the guard added last commit, all of them places where a rule was enforced on one path and walked past on another. The veto could never be recorded. The probe asked whether the gateway SSL directory accepts writes, and the record - and its generation fence - are written into that same directory. A node that cannot write there cannot write down that it cannot write there, so the finding was lost in exactly the state it exists to report. It is no longer carried in the record at all: the doctor collects it beside the record so an archive carries it, and update asks live on the node itself. The probe did not reproduce the write it certified. It created a zero-byte file, which a full disk accepts happily - it has an inode to spare and no data blocks - and it never established that the two files the gateway has bind-mounted could be overwritten. Those are replaced in place rather than recreated, so their own permissions decide, not their directory's. It now writes a certificate-sized file where the helper writes, and opens each target for update without truncating it. The ZeroSSL warning printed a request, and could run one, before any record was read. The update gate treated an unreadable record as an absent one, which is the fail-open this whole guard exists to prevent, and passed a successful record through without checking it described a failure. Both now use the same state handling as the reporting path. The doctor reached a request by two routes the derivation had already closed: the provider-switch ending was keyed on the cause's own remedy rather than the decided action, and the central request renderer treated everything short of an outright refusal as permission. The spent-issuance ending printed the command directly beneath the sentence withholding it, which is the second weekly certificate that state exists to protect. The legacy configuration analyser predates the record and ends each of its own checks in a request. Those are withheld now too - for ZeroSSL the allowance is three in a node's lifetime, not five a week. Tests: four mutations checked - an empty probe file, dropping the target-file check, restoring the command under the withholding sentence, and the legacy analyser ignoring the veto. The update test now breaks real storage rather than setting a flag, because update asks the filesystem rather than trusting what was recorded. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Three rounds of review found branches printing a certificate request that the shared derivation had already withheld - a different branch each time, and each round's fix uncovered more of them. Thirty sites across six files could build that command, and each decided for itself whether printing it was safe. Fixing them one at a time was not converging, so the decision is no longer made per branch. `renderObtainCommand` is the only thing that produces the command: callers ask for it and are given either the command or the reason it is being withheld, and cannot tell which without looking. A test fails if the raw command reappears in any surface that has the guidance to hand, so a branch that forgets to consult it is a failing build rather than a report an operator acts on. Wiring it up immediately found one: a caller that did not pass the config rendered `--config undefined`, which an operator would paste and run against the wrong node or none. It now refuses rather than rendering that, and a test pins it. The storage-writability guard added two commits ago is removed. It was meant to withhold a request when a certificate could not be saved, but it could not persist its own finding - it examined the directory the record is written into - and, more seriously, it vetoed nodes that were fine. An operator who hardens the private key to 0400, which this repository explicitly supports, would have been told their storage was broken and refused the command; the saver chmods before writing and would have succeeded. Darkening a correctly-secured node is worse than the narrow case the guard defended, which is one weekly certificate lost to a disk that filled during a save. That case is left as a documented residual. What stays from that work is the part that was sound: `update`'s interactive prompt reads the renewal record before offering to obtain, and unreadable records are no longer read as absent ones. Tests: the chokepoint is mutation-checked by reintroducing a raw command in the doctor, which the guard catches. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Every command dashmate prints carried `--config <name>`, including for the config it would act on anyway. On a node with one config - which is most of them - that names something the operator cannot act on and lengthens every command in every report. The flag is now omitted when the config is the default, and printed for every other one. That distinction is not decoration: an operator running several nodes who pastes a bare command obtains a certificate for, restarts, or bypasses a check on a different one. When the default cannot be established - a collected archive from another machine, which does not carry it - the flag is printed, because being explicit is only wasteful while being wrong is not recoverable. The flag carries its own leading space, so a command reads correctly whether it appears or not. Without that, omitting it leaves `dashmate doctor ` with a trailing space, or `dashmate logs dashmate_helper` with two. All 46 interpolations were adjusted to sit directly against the preceding word. The default is read through a tolerant helper. Tasks, analysers and reports are constructed in places that have no configuration file at all, and an unknown default is not a failure - it means the flag stays, which is the safe direction. Tests: the omission, the retention for other configs, the unknown-default fallback, and that a command is well formed with the flag and without it. Two mutations checked. A third survived and was worth the finding: the explicit absent-default check is only load-bearing for a config literally named `null` or `undefined`, which config names permit, so that case is now pinned rather than left to a stringified comparison.

Preliminary review — Codex only

The targeted renewal diagnostics suite passes with 190 tests, and the spent-issuance remedy fixed since the previous review now correctly omits the obtain command. Ten blocking issues remain: renewal evidence can still be lost or bypassed through Docker, persistence, archive, and legacy-diagnostic paths, while cause-specific port guidance remains vulnerable to incorrect classification; one valid lower-severity CodeRabbit timer-cleanup suggestion is omitted because the 10-finding budget is fully consumed by blockers.

  `analyseSamplesFactory` runs this legacy SSL analyzer before the renewal-aware gateway analyzer, and these ZeroSSL and Let's Encrypt remedies still print raw `dashmate ssl obtain` or `--force` commands without consulting the shared renewal decision. A rate limit, quota exhaustion, support-only failure, unreadable record, or outstanding issuance can therefore produce conservative guidance from the gateway analyzer and an opposing runnable command from this analyzer.

- [BLOCKING] packages/dashmate/src/ssl/renewal-failure.js:237-252: Responder-injected ACME types still choose the port-80 repair
  `readAcmeCause()` scans every ACME URN in the complete lego message, including URNs inside response content quoted by an `unauthorized` problem, and prefers `connection` over `unauthorized`. A wrong responder can therefore return content containing `urn:ietf:params:acme:error:connection`, causing the run to be classified as `PORT_80_UNREACHABLE`. Although all message-derived codes share the same broad remedy class, `renderPortEightyHint()` still branches on the selected code and sends the operator to firewall/NAT repair instead of locating the responder. Parse only the authority-owned problem type, or use neutral port-80 guidance that covers both states whenever the type came from untrusted message text.

  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3849467305)
  `VerificationServer.waitForServerIsResponding()` returns the same `false` after a connection failure and after receiving a non-successful HTTP response. Both become `PORT_80_CHECK_FAILED`, but `renderPortEightyHint()` sends that code through its firewall, NAT, and port-opening fallback. A proxy, router page, or unrelated server returning 403 or 404 therefore receives unreachable-port instructions even though something answered. Preserve whether an HTTP response was received, or make the neutral remedy explicitly cover both reachability and wrong-responder states.

  `requestApi.createHeaders()` throws `Error('Invalid ZeroSSL API key')` for null, empty, whitespace-padded, or otherwise unusable keys. The scheduled ZeroSSL path passes the optional configuration value directly to `getCertificate()`, but this local error has no numeric provider code and reaches the `UNKNOWN` fallback. This conceals a known credential problem behind support-only guidance. Use a typed local authentication error, or otherwise classify this repository-owned failure as `PROVIDER_AUTH` without relying on provider-controlled text.

  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3856939821)
  A non-zero lego exit is still converted to a generic `Error` before `ctx.certificateObtained` is set and before artifact checks can raise `LegoArtifactsMissingError`. Lego obtains the certificate before its storage `SaveResource` step, so a full filesystem or permission failure during that later step can consume an issuance while this path records only `UNKNOWN`, without `issuanceSpentAt`. A subsequent repairable failure can overwrite the unknown result and expose another certificate request. Preserve a trustworthy post-issuance signal for this path without allowing responder-controlled ACME detail to manufacture a sticky issuance marker.

  `startLegoContainer()` awaits `container.start()` and returns only afterward; `collectContainerOutput()` is then called on the returned container. With `AutoRemove: true`, a fast-failing lego process can exit and be removed between completion of the start request and the subsequent `logs({ follow: true })` request. The code also calls `container.wait()` without awaiting resolution of the logs-attachment promise.

  The explicit `UNREADABLE` state is handled conservatively, but a sample marked `PRESENT` for which `RenewalRecord.fromObject()` returns `null` is not. In that case `renewalRecord` and `failedRenewal` are null while `isRecordUnreadable` remains false, so `deriveRenewalGuidance()` permits `SAFE_ACTION.OBTAIN`.

  The generation file's absence check and initial zero write occur before the exclusive lock is acquired.

  The lock has no ownership token. A contender removes it solely because its unrefreshed mtime is more than ten seconds old, while every holder's release callback unconditionally removes the current lock path. If the original process is suspended, a replacement can break the lock and enter its mutation; when the original resumes, it can still write stale state and delete the replacement owner's lock, admitting another writer. Use ownership-aware acquisition, mutation, and release, or do not reclaim a lock solely from this fixed mtime threshold.

Preliminary review — Codex only

At the exact head, all ten prior blockers remain; the latest revert changes config-name rendering and does not address them. The defects can still lose or bypass issuance evidence, allow generation claims to collide, and prescribe unsafe or materially incorrect repairs; the downstream gateway-save variant is folded into the first finding, while one valid timer-cleanup suggestion is omitted under the 10-finding budget.

- [BLOCKING] packages/dashmate/src/doctor/analyse/analyseConfigFactory.js:94-193: Legacy SSL findings still prescribe requests forbidden by the renewal record
  `analyseSamplesFactory` runs this legacy SSL analyzer before the renewal-aware gateway analyzer, but the ZeroSSL and Let's Encrypt remedies here still print raw `dashmate ssl obtain` and `--force` commands without consulting the shared renewal decision. A rate limit, quota exhaustion, support-only failure, unreadable record, or outstanding issuance can therefore produce conservative no-obtain guidance from the gateway analyzer and an opposing runnable command from this analyzer. Route every certificate-request remedy through `renderObtainCommand()` with the applicable guidance, or suppress these duplicate legacy certificate findings when the gateway analyzer owns the diagnosis.

  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3856939821)
  Every non-zero lego exit is converted to a generic `Error` before `ctx.certificateObtained` is set and before artifact checks can raise `LegoArtifactsMissingError`. Lego obtains a certificate before its later certificate-storage step, so a full filesystem or permission failure during that step can consume an issuance while this path records `UNKNOWN` without `issuanceSpentAt`. The same post-issuance gap exists immediately downstream: filesystem, chmod, read-back, and pair-validation failures in `saveCertificateTask.js:41-87` are also propagated as generic errors after `ctx.certificateObtained` was set, but the scheduler receives only the error and cannot see the task context. A later repairable failure can overwrite either unknown result and expose another certificate request; preserve a typed, locally trustworthy issued-but-not-saved signal across both persistence stages, and remove the downstream pair-mismatch instruction that unconditionally recommends another issuance.

  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3856939826)
  `startLegoContainer()` awaits `container.start()` and returns only afterward; `collectContainerOutput()` is then called on the returned container. With `AutoRemove: true`, a fast-failing lego process can exit and be removed between completion of the start request and the subsequent `logs({ follow: true })` request. Calling `container.wait()` without first confirming that the logs promise has attached introduces a second window, but fixing only that second window is insufficient. Attach the output stream after container creation but before starting it, or disable auto-removal and remove the container only after output has drained.

  `VerificationServer.waitForServerIsResponding()` returns the same `false` after a connection exception and after receiving a non-successful HTTP response. Both paths become `PORT_80_CHECK_FAILED`, but `renderPortEightyHint()` sends that code through its default firewall, hosting-provider, NAT, and port-opening instructions. A proxy, router page, or unrelated server returning 403 or 404 is therefore diagnosed with unreachable-port repairs even though something answered.

  `requestApi.createHeaders()` throws a plain `Error('Invalid ZeroSSL API key')` for null, empty, whitespace-padded, or otherwise unusable credentials. The scheduled ZeroSSL path passes the optional configuration value directly to `getCertificate()`, but this local error has no numeric provider code and reaches the `UNKNOWN` fallback.

  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3873455628)
  `readAcmeCause()` scans every ACME URN in the complete lego message and prefers `connection` over `unauthorized`. The authority quotes content fetched from the public HTTP-01 responder inside an `unauthorized` problem, so a wrong responder can include `urn:ietf:params:acme:error:connection` in its page and make this function select `PORT_80_UNREACHABLE`. Although the broad safe-action class is shared, `renderPortEightyHint()` still branches on the selected code and sends the operator to firewall and NAT repair instead of locating the responder. Parse only the authority-owned top-level problem type, or use neutral port-80 guidance whenever classification came from message text that can contain responder-controlled content.

  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3852942100)
  The explicit `UNREADABLE` state is handled conservatively, but a sample marked `PRESENT` for which `RenewalRecord.fromObject()` returns `null` is not. In that case `renewalRecord` and `failedRenewal` are null, while `isRecordUnreadable` checks only the original state and remains false. `deriveRenewalGuidance()` consequently permits `SAFE_ACTION.OBTAIN`. A malformed, damaged, future-format, or hostile archived object can therefore erase a spent or uncertain issuance guard. Treat `PRESENT` plus failed reconstruction as unreadable and withhold certificate requests.

  The generation file's absence check and initial zero write occur before the exclusive lock is acquired. Two first-use processes can both observe the file as absent; after one initializes the file and claims generation 1, the other's delayed atomic zero write can replace the high-water mark before it acquires the lock, allowing it to claim generation 1 as well.

  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3854667857)
  `readPrevious()` maps every repository state other than `PRESENT` to `null`. If the prior file is malformed or unreadable, the next scheduled failure therefore replaces it with a fresh record carrying neither issuance marker; the unit test explicitly expects corrupt history to be replaced this way. Doctor is conservative only until that write, after which a repairable failure can expose `ssl obtain` even though the discarded record may have contained spent or uncertain issuance evidence. Preserve uncertainty when prior state exists but cannot be read, or refuse to overwrite it with state asserting no outstanding issuance until a certificate successfully lands.

Five findings from review, three of them raised independently by more than one reviewer. The generation file was created before the lock that guards it, so two processes reaching an unclaimed fence could both initialise it and one could then claim a generation the other had already taken. It is created under the lock now. The lock carried no owner. A holder whose lock had been broken as stale still released on its way out, deleting whatever lock was there by then - the next holder's - leaving two processes believing they held the same fence. Each holder now writes a token and removes only a lock still carrying it. A record that exists and cannot be read was treated as an absent one, so the next failure wrote a fresh record with no markers. That record may be the one saying a certificate was issued and never saved, so it now fails closed and the issuance stays uncertain. A ZeroSSL key that is absent, empty or malformed never reaches the provider, so there is no numeric code to classify it by. It was landing on "could not work out why" and sending an operator to support for something one command repairs. It is a typed error now, and reported as a rejected account. The drain timer is cleared whichever side of the race wins, instead of holding the buffered output and the event loop for another ten seconds on every renewal. Documentation links are gathered in one module. The SSL-certificates anchor appeared three times in a single file and the troubleshooting article was a separate constant elsewhere; a link kept in several places is one that gets updated in some of them, and this PR has already shipped a link that answered 404. All five are asserted to resolve. Not changed, and worth recording: the log attach still happens after the container starts. Both alternatives were tried against a real Docker and are worse. Attaching to a created-but-unstarted container yields an empty stream, which lost the authority's reason on four Pebble cases. Retaining the container collides with the single shared container name - the stale-container cleanup force-removes whatever holds it, killing a live lego, seen as exit 137. The residual is documented where the container is created. Tests: Pebble's deliberate nonce rejection is disabled for the suite. It made a port-80 case fail on a nonce before validation ever ran, so a test written to exercise one failure silently exercised another; what a survived nonce does beside a real failure is pinned deterministically in the unit tests instead. Six mutations checked, two of which exposed tests that could not fail. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

The stream was requested and then immediately waited on, so the attach was in flight while the container could already have exited and been auto-removed. It is awaited now: the daemon has handed the stream over before the result is waited on, which is what the ordering was meant to guarantee rather than merely start. Attaching earlier still does not work - a container that has not been started has nothing to follow and the stream closes empty, which lost the authority's reason on four Pebble cases when it was tried. Tests: the double hands the stream over a tick later, as a daemon call does, so a test that only checked the request had been made no longer passes. Dropping the await fails it.

Seven in-scope blockers remain: issuance evidence can still be lost, concurrent stale-lock owners can still mutate or remove another owner’s fence, malformed archives and legacy diagnostics can expose unsafe obtain commands, and both provider paths can present materially incorrect port-80 repairs.

  Every non-zero lego exit is still converted to a generic `Error` before `ctx.certificateObtained` is set.

The downstream gateway installation has the same gap: filesystem, chmod, read-back, and certificate/key validation failures in `saveCertificateTask.js` propagate as generic errors after `ctx.certificateObtained` is true, but the scheduler receives only the error and cannot inspect that context; the pair-mismatch error also directly recommends another forced obtain.

  `startLegoContainer()` awaits `container.start()` before returning, and only afterward does `runLego()` call `container.logs()`. With `AutoRemove: true`, a fast-failing lego process can exit and be removed before the start request returns or in the interval before the logs request is issued.

  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3854667853)
  The ownership token reduces the previous race but does not make ownership checks atomic. An old holder can read its token at line 139, then a contender can remove the now-stale lock and create a replacement before the old holder calls `rmSync`, allowing the old holder to delete the replacement owner’s fence. More importantly, ownership is never revalidated before the protected mutation: a process suspended for more than ten seconds can resume after a contender has reclaimed the lock and still write stale generation or record state. Use a lock primitive that atomically verifies ownership for mutation and release, refresh the lease while held, or avoid reclaiming solely from an unrefreshed fixed mtime.

…ding it A malformed record read as no record at all. Only the sample's state was checked, so a sample marked present that does not parse - a damaged archive, a format from a later build, one supplied by someone else - left a null record with nothing marking it unreadable, and the derivation then allowed a request. It is treated as unreadable now, which is what the state already meant. The legacy configuration analyser prescribed its own requests without consulting the record. It runs before the renewal-aware analyser in the same report, so a node whose recorded cause forbids asking again read "do not obtain" from one problem and a runnable command from the next - and would follow the command. Its certificate remedies go through the shared decision now. Two port-80 repairs claimed more than was established. dashmate's own check answers the same way when nothing replies and when something replies wrongly, and its finding was routed through the firewall instructions - sending an operator to open a port that was already open and answering. It now covers both readings and starts by asking what is listening. And which of the two message- derived port-80 causes gets named comes from text the authority quotes back, which is whatever answered on that port: the action was already identical either way, but the instructions were not, so each now names the other. A post-issuance save failure told the operator to obtain again as though it were free. A certificate had already been issued at that point and counts against the weekly limit whether or not the files are usable, so it says that, and asks for the local repair first. Tests: four mutations checked - the unreadable widening, the legacy gate, the neutral check-failed hint, and the cross-references. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

  `withheldRequest()` replaces a legacy remedy only when the shared decision is `DO_NOT_OBTAIN`. Provider exhaustion and plan failures instead produce `SWITCH_PROVIDER`, so the helper returns `null` and the legacy ZeroSSL remedies at lines 143-189 retain commands that request another ZeroSSL certificate. The renewal-aware gateway analyzer directs the same operator to switch to Let's Encrypt, producing contradictory instructions in one report. The helper also reconstructs every failed record without calling `record.appliesTo(...)`; the configuration-watcher handover does not clear the previous provider's record, so a stale spent or uncertain record can suppress a valid request after a provider switch even though the gateway analyzer correctly ignores it. Apply the provider/certificate applicability check here and route every legacy certificate request through the shared renderer for all safe-action values, including `SWITCH_PROVIDER`.

  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3854667853)
  The ownership token protects only the common release path; it does not preserve exclusivity after stale-lock reclamation. If a holder is suspended for more than `LOCK_STALE_MS`, another process can remove its lock and perform a newer generation or record mutation. The original process can then resume and execute `fn()` without revalidating ownership, overwriting newer state. Release also remains a read-then-remove race: after the old owner reads its token at line 139, a contender can reclaim and recreate the stale lock before line 140, causing the old owner to remove the contender's lock. Use a refreshed lease with ownership validation before mutation and an ownership-aware atomic release, or avoid reclaiming a lock solely from its fixed, unrefreshed mtime.

…each the legacy checks Two blockers from review, both places where a guard covered the moment it was taken rather than the moment it mattered. The generation fence validated ownership when the lock was acquired and never again. A holder suspended past the stale threshold has its lock reclaimed, and another process may already have written newer state - so when the first one resumed it overwrote it. Every mutation now revalidates immediately before writing and refuses if the lock is no longer ours. The release remains a read-then-remove that is not atomic, and that is now stated where it happens: the window is microseconds, opens only after a holder has already been suspended past the threshold, and a mutation by either process is still refused, so what is lost is exclusion rather than state. The legacy configuration analyser consulted the shared decision only for an outright refusal. Quota and plan failures produce a provider switch instead, so its ZeroSSL remedies went on asking that provider for another certificate while the renewal-aware analyser in the same report said that provider will never issue one again. It also rebuilt any failed record without checking the record still describes this node, so a record left behind by a provider switch could suppress a request that had become valid - the renewal-aware analyser already ignores those, and the two must not disagree. Tests: three mutations checked - dropping the pre-write ownership check, the switch case, and the applicability check. The takeover is staged while the operation is under way rather than before it starts, so the revalidation is actually exercised. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

  The provider-switch portions of this finding are fixed, but this analyzer still supplies only the configured provider to `record.appliesTo()`. The collected `gateway.installedCertificate.validFrom` identifies when a newer certificate overtook an earlier failed renewal; the gateway analyzer passes that value and ignores the stale record. If a same-provider certificate is installed after the recorded failure and later develops a legacy SSL finding, this analyzer still treats the old failure as applicable and can replace the valid repair with stale no-obtain or switch-provider guidance. Pass the installed certificate's `validFrom` so both analyzers apply the record to the same certificate.

  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3854667853)
  The new `stillOurs()` checks remain separate from the mutations they authorize. After line 367 validates the token, the process can be suspended until the fixed lease is stale; another process can then remove the lock, acquire a replacement, advance the generation, and write newer state before the original process resumes at line 371 and overwrites it. The same check-then-mutate window exists in `claimGeneration()` and `remove()`. Release also remains read-then-remove: a contender can replace a stale lock after the token read at lines 162-163, causing the old owner to delete the replacement fence. Use a refreshed lease whose ownership remains effective through mutation and release, an ownership-aware lock primitive, or stop reclaiming locks solely from an unrefreshed mtime.

The lock was reclaimed once it had gone unrefreshed for ten seconds, which takes it away from a process that is merely slow rather than dead. That process then resumes and writes, and no amount of checking ownership beforehand closes the gap - the check and the write are separate operations, and the lock can be taken between them. Every attempt to fix this by tightening the check ran into the same window. So the lease is gone. A lock records the process that holds it, and is now reclaimed only when that process no longer exists - which is the question the lease was approximating. A holder that does not exist cannot resume and overwrite anything, and a holder that does exist keeps its lock however slow it is. Waiting for a live holder times out as before, so a genuinely stuck one still cannot block bookkeeping for good. The legacy configuration analyser also applied a failure that a newer certificate had already overtaken. It supplied only the provider to `appliesTo()`, while the renewal-aware analyser supplies the installed certificate's date and ignores such a record - so the two contradicted each other in the same report. Both now scope the record to the same certificate. Tests: reclaiming from a live holder, and refusing to reclaim from a dead one, are both pinned. Two mutations checked; one survived first time, because nothing covered the certificate date at all until this added it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Preliminary review — Codex only

The latest head fixes the legacy analyzer's certificate-applicability check, and the exact-head CodeRabbit findings are either fixed or inapplicable. Three blocking issues remain: the renewal fence relies on namespace-local PIDs and exposes incomplete ownership metadata, while post-issuance gateway save failures still lose the sticky issuance marker.

- [BLOCKING] packages/dashmate/src/ssl/renewalRecord/RenewalRecordRepository.js:166-173: The lock is reclaimable before acquisition publishes its owner
  `openSync(lockPath, 'wx')` makes an empty lock file visible before the following `writeFileSync` publishes the owner token. A contender that observes `EEXIST` during this interval parses the empty file as having no live holder, removes it, and acquires a replacement; the first process then writes its token only to the already-unlinked descriptor and returns as though acquisition succeeded. On first use, `#fenced()` consequently returns `false` before invoking the callback, so `claimGeneration()` returns a boolean despite promising a numeric generation. Both renewal schedulers accept that value and continue, but their later outcome writes are fenced out by the newer generation, defeating the PR's persistence guarantee. Publish ownership as part of an atomic acquisition protocol, or treat absent or incomplete owner metadata as an acquisition in progress rather than immediately reclaiming it.
- [BLOCKING] packages/dashmate/src/ssl/renewalRecord/RenewalRecordRepository.js:52-66: A stale-lock takeover lets the old owner release the new owner's fence
  (existing thread: https://github.com/dashpay/platform/pull/4476#discussion_r3854667853)
  The lock file is shared between the host CLI and `dashmate_helper` through the bind-mounted Dashmate home directory, but the helper uses Docker's default private PID namespace. The PID stored by one side therefore does not identify the same process on the other side: the helper can receive `ESRCH` for a live host owner and remove its lock, while the host can interpret a helper PID as an unrelated live host process and refuse to reclaim a dead lock. Once a live lock is incorrectly reclaimed, the separate `stillOurs()`-then-mutate and read-then-remove windows allow the old owner to overwrite newer generation or renewal state or remove a replacement lock. Independently, two same-namespace contenders can both determine that an old PID is dead; after one removes the old lock and creates its own, the other's already-authorized `rmSync` can delete that new lock. Use an exclusion mechanism whose ownership is valid across PID namespaces, or an atomic ownership-aware reclamation protocol that does not infer ownership from namespace-local PIDs.

In `packages/dashmate/src/listr/tasks/ssl/saveCertificateTask.js`:
- [BLOCKING] packages/dashmate/src/listr/tasks/ssl/saveCertificateTask.js:42-93: Post-issuance gateway save failures lose the sticky issuance marker
  The Let's Encrypt task sets `ctx.certificateObtained = true` before invoking this shared save task, so certificate writes, key writes, chmod operations, read-back, and pair validation all run after the authority has issued and counted the certificate. Every failure here is still propagated as a plain error, including the explicit pair-mismatch error, and the scheduler receives only that error rather than the task context. `classifyRenewalFailure()` sets `CERTIFICATE_ISSUED_NOT_SAVED` only for a carried `LegoArtifactsMissingError`, so these failures are recorded as `UNKNOWN` without `issuanceSpentAt` or `issuanceUncertainAt`. The immediate unknown guidance withholds another request, but a later repairable failure can overwrite it and restore `ssl obtain`; the pair-mismatch message itself also ends with an unconditional forced obtain command. Carry a typed post-issuance save failure whenever the task context confirms issuance, classify it as issued-but-not-saved, and remove direct obtain advice while that sticky marker remains.

… leaves The previous commit made lock reclamation depend on whether the recorded pid was still alive. That is invalid here. The helper holds this lock from inside a container - `dashmate_helper` bind-mounts the same home directory at the same path - while `dashmate doctor` and `dashmate ssl obtain` hold it from the host. Their pids come from different namespaces, so asking the kernel about one from the other names an unrelated process or none at all. It replaced a documented imprecision with a mechanism that cannot answer the question it asks. Reclamation is by age again, and the comment now states the residual exactly rather than claiming the generation makes the pairing correct: a holder suspended by the OS past the threshold, across a few synchronous filesystem calls, while another process completes a takeover and a newer mutation, and then resumes last. The generation handles ordinary supersession; it does not close that window, and callers may pass no generation at all. A kernel advisory lock has the right semantics - held through suspension, released when the process dies - and is not adopted here: Node exposes no `flock`, this package has no native locking dependency, and coherence between a macOS host and a Linux container through Docker's file sharing is unproven. Taking that on needs a host-versus-container test first, which is a larger change than this PR should carry. The certificate-applicability fix from the reverted commit is kept.

Where this stands, and the three things deliberately left open

Every review thread has been answered and 29 of 30 are resolved. Three findings are accepted residuals rather than fixes, and since the automated review derives its blocker list from the diff it will keep raising them, they are collected here with the reasoning so a reader does not have to reconstruct it from the threads.

1. The renewal fence is reclaimed by age

A lock is broken once it has gone unrefreshed past a threshold. That takes it from a holder that is merely slow, not dead.

Three attempts at closing it produced three findings: an ownership token (guards release only), revalidation before every mutation (check and write are still separate operations), and reclaiming only from a dead pid — which was wrong and has been reverted. The helper holds this lock from inside a container that bind-mounts the same home directory, while dashmate doctor and ssl obtain hold it from the host; their pids are in different namespaces and are not comparable.

The residual, exactly: a holder suspended by the OS past the threshold, across a few synchronous filesystem calls, while another process completes a takeover and a newer mutation, and then resumes last.

A kernel advisory lock (flock/OFD) has the right semantics — held through suspension, released when the process dies. It is not adopted because Node exposes no flock, this package has no native locking dependency, and coherence between a macOS host and a Linux container through Docker's file sharing is unproven. That needs a host-versus-container test before it is a fix rather than a hope.

2. A certificate issued and then not saved leaves no marker

lego can obtain a certificate and fail to write it; it exits non-zero, and dashmate only records that an issuance happened on a clean exit. A later attempt can therefore spend a second certificate from the weekly allowance.

A guard was built for this and removed. It could not persist its own finding — the record it writes lives in the directory being diagnosed — and, more seriously, it refused nodes that were fine: an operator who hardens the private key to 0400, which saveCertificateTask supports by chmod-ing before writing, was told their storage was broken and denied the command. Darkening a correctly-secured node is worse than the case it defended.

This condition exists on the base branch; the PR does not widen it. What did change: a post-issuance save failure no longer reads as a free retry.

3. The log attach still happens after the container starts

The attach is awaited before the result is waited on, which closes the later race. The window before attachment begins remains.

Both suggested closures were tried against a real Docker and are worse. Attaching to a created-but-unstarted container yields an empty stream — nothing is running to follow — which lost the authority's reason on four Pebble cases. Disabling auto-removal collides with the single shared container name, whose stale-container cleanup force-removes whatever holds it, killing a live lego (exit 137 across the suite).

Verification

815 unit tests and 16/16 Pebble integration tests against a real ACME server, 0 lint errors. Every guard added in this PR was checked by mutation — reverting the fix and confirming a test fails. That found five tests which could not fail, including one that only passed because an unrelated gate shielded it.

`claimGeneration` promises a number and its callers carry the result as one. A guard added with the pre-mutation ownership check returned `false` instead when the fence was taken over while being created, so a scheduling chain could go on holding `false` as its generation - and every later write was then fenced out by comparing against it, recording nothing at all. That is the one outcome the record exists to prevent, and it happened silently. It throws now. A chain that cannot establish which generation it holds has nothing useful to record, and saying so loudly is the only honest option. The other half of that finding - a contender reclaiming the empty lock file between its creation and the token being written - does not apply since reclamation went back to age: a lock created moments ago is nowhere near the threshold, so nothing breaks it during that window.
