+# Proposal: operator checklist for remote qualification
+
+Status: **Implementation proposal; human PR review required.** Issue [#158](https://github.com/abruption/session-peer-ts/issues/158),
+following [#23](https://github.com/abruption/session-peer-ts/issues/23).
+Draft date: 2026-10-21. No release version is assigned; priority is P2.
+
+## Purpose and boundary
+
+Help an operator assess one explicitly provisioned, exact-version TypeScript
+installation using a small evidence worksheet. The result describes checks;
+it neither activates an installation nor authorizes another action.
+
+The [remote deployment ADR](remote-deployment.md) remains a historical proposal
+with dated experiments. This checklist does not implement its F1–F6 follow-ups
+or adopt its journal, receipt, lock, activation or recovery machinery. The
+2026-10-20 decision in #23 supersedes its earlier release planning: Draft #155
+is deferred and excluded from 0.5.0. Its commits and evidence remain historical;
+they are not the implementation starting point for this proposal.
+
+Installation, rollout, repair, activation, rollback and retention belong to the
+operator and the installation's owning manager. No manager takeover, installer,
+runtime update, source-streaming fallback, distributed lock, caller accounting,
+receipt ownership, recovery/resume protocol or automated cleanup is introduced.
+The owner explicitly requested a repository-only read-only reporter extension on
+2026-10-21 after reviewing the checklist. Its limited input/output and reader
+contract is specified in [the reporter design](remote-qualification-reporter.md).
+It automates selected local metadata observations, not this whole workflow.
+The production CLI, wire schema and qualification/authority boundaries do not change.
+
+Existing exact-version SSH preflight, host-key checks, submission/unknown and
+no-resend behavior remain requirements. Passing this checklist proves neither
+message delivery nor ACK and grants no permission to switch callers, delete
+files, break locks, publish receipts or clean up storage. Existing runtime
+handoff and ACK contracts are outside this design.
+
+## Operator workflow
+
+1. Select the destination, account, installation path, owning manager and exact
+   intended local/remote version. Record the intended OS/architecture and runtime
+   cell. If selection or ownership is uncertain, record that uncertainty and stop
+   checks that depend on it; do not infer ownership from a marker or directory name.
+2. Start a new worksheet with every check `not_checked`. Inspect only explicitly
+   selected metadata and record its source and observation time. Reading a file
+   never entails executing a discovered wrapper, Node, npm or agent executable.
+3. Assess the static and operator-attestation checks below. Preserve missing and
+   conflicting evidence. Stop dependent checks on `fail`, `unknown` or
+   `unsupported`; remediation is a separate human decision.
+4. If separately authorized, the operator may execute a specifically selected
+   existing bounded diagnostic, then record its exact command, scope and result.
+   Select the local CLI by its explicit absolute path. For a remote diagnostic,
+   include the selected absolute wrapper in `--remote-bin` and specify
+   `--remote-platform win32` for Windows, using paths accepted by the existing
+   CLI. Do not choose a default PATH-based invocation for this assessment.
+   Missing path/platform binding makes attribution to the selected installation
+   `unknown`, even if some same-version CLI returned success. An absolute path
+   is an invocation choice, not authentication or proof against later replacement.
+   Skipping that step leaves its check `not_checked`, without borrowing old results.
+5. Review the individual results and evidence limits. Record unresolved cells and
+   the next human decision. End the assessment without changing the installation.
+
+This document grants no live experiment authorization. There is no default SSH
+connection, registry request, executable discovery/run or agent contact. A future
+diagnostic choice must name the destination, inputs, effects and stopping bound
+before execution. `doctor --host` invokes SSH and the remote CLI;
+`doctor --check-return-route` can initiate a return SSH probe. `send --dry-run`
+means validation without submission, not a guarantee of zero writes, process
+launches or network activity across its selected route. Diagnostic labels alone
+do not establish an effect boundary; installed behavior and options need review.
+No real send, ACK request or peer notification is part of this checklist.
+
+## Check states
+
+Each check is local to one assessment invocation and one stated predicate:
+`not_checked` → `pass`, `fail`, `unknown` or `unsupported`.
+
+| State | Meaning |
+| --- | --- |
+| `not_checked` | No assessment of this predicate was attempted in this invocation, including a deliberately skipped diagnostic. |
+| `pass` | Sufficient current evidence supports the precise predicate, using its recorded evidence kind and scope. |
+| `fail` | Sufficient current evidence demonstrates the predicate is false, such as an established version mismatch. |
+| `unknown` | Attempted assessment cannot establish the predicate: missing, unreadable, stale, ambiguous or conflicting evidence, including interrupted diagnostics. |
+| `unsupported` | The selected check method cannot assess this platform/runtime/path case; record the specific limitation. This is neither a pass nor a compatibility claim. |
+
+An absent selected file is `fail` for “the selected file exists” but `unknown`
+for “this installation uses the intended runtime.” A genuinely unsupported
+runtime is `fail` for a supported-runtime requirement when established; it is
+not hidden as an unsupported inspection method. Contradictory sources cannot
+be resolved by choosing the favorable result. Record the conflict as `unknown`
+unless authoritative scoped evidence establishes the predicate is false.
+
+A later inspection is a new observation, recorded alongside the earlier one;
+it does not erase a contradiction without explaining its resolution. There is
+no aggregate `pass`, automatic “qualified” designation or authorization token.
+All checks passing still describes only their individual predicates and scopes.
+
+## Evidence worksheet
+
+Use ordinary text or a table; no machine format or persistence protocol is
+required. For each check record the predicate, state, evidence kind, exact source,
+observed time, destination/account/path and relevant version/runtime identity,
+plus the result and limits. Keep sensitive command output out of shared notes.
+
+Distinguish these evidence kinds:
+
+- **Static metadata:** inspected artifact/version text, path, wrapper contents,
+  lockfile or computed hash. It proves only what was read at that time; it cannot
+  prove the actually running version, current caller use, storage ownership or
+  that a declared runtime path is the one a process uses.
+- **Operator attestation:** a named operator's statement about manager ownership,
+  intended caller selection or a command result. Record when and where it was
+  observed and whether output is available; do not relabel it as executed evidence.
+- **Executed diagnostic:** the exact command actually run in this invocation,
+  installed CLI/runtime version evidence, destination/account, time, exit status,
+  relevant result and observed limits. An observed banner identifies that command
+  invocation, not every process, caller or storage owner on the host.
+- **Historical or synthetic evidence:** dated previous runs or fixtures, kept as
+  references, not replacement current results. An explicitly selected historical
+  digest may be an input to a new comparison predicate: record its source, path,
+  algorithm and original observation time, then measure the current input in this
+  assessment. The historical check's `pass` is never inherited. Without that
+  baseline identity or a current measurement, comparison is `unknown`.
+  Native destination execution must be identified separately
+  from fake SSH, local fixtures and CI. None supplies a skipped current check.
+
+Freshness is scoped to the observation, not a reusable time-to-live. A changed
+artifact, runtime, destination, account, path, manager or invocation context
+invalidates conclusions that depend on it; reinspect or record `unknown`. Record
+both the declared identity and what was observed. Do not infer a source commit
+from an equal version banner: current wire preflight checks the version line.
+Combined conclusions depend on observations referring to the same installation
+and context. A path can change between observations; repeat an applicable
+inspection or state the continuity limit. No atomic snapshot is promised.
+
+Hash equality means matching computed digests under the recorded algorithm and
+scope at the observation times. It is not an unconditional proof of byte identity. It authenticates no code and proves no current
+use or ownership. A missing/uncomputed hash (`null`, if so transcribed) is unknown,
+never “unchanged”; two null hashes are not a successful comparison.
+
+| Minimal check | Evidence sufficient for its limited predicate |
+| --- | --- |
+| Installation and manager are explicitly selected | Operator attestation naming destination/account/path and manager; uncertain ownership remains unknown. |
+| Selected artifact metadata matches the intended version | Current static inspection of the named artifact; independently distinguish any executed banner result. |
+| Declared runtime/path/native dependency match the intended cell | Explicit metadata inspection, with missing facts unknown; native loading and actual runtime selection require separately scoped executed evidence. |
+| Current measured digest matches an explicitly selected baseline for a named file | Record baseline source/path/algorithm/time and a current measurement in this assessment. Matching digests do not prove continuous preservation between observations, current use or ownership. Missing either input is unknown. |
+| Selected existing diagnostic returned the stated result | Actual authorized invocation/output with the explicit local CLI path, remote wrapper/platform where applicable, and selected agent scope. PATH-only results cannot establish attribution. `doctor` completion alone proves no readiness, native lock or send authorization. |
+| Remaining destination cell has bounded native evidence | Exact dated OS/arch/account/runtime/package/native-check scope; no expansion to another cell or complete platform support. |
+
+## Remaining #23 work and evidence limits
+
+This is a classification of open work, not a new completion claim. “Live” below
+means separately scoped native destination execution; none was run for this design.
+
+| Remaining criterion | Appropriate evidence/work | Current disposition |
+| --- | --- | --- |
+| Explicit same-version provisioning and supported absolute runtime/native dependency | Docs + static metadata + operator selection; live invocation/native load for actual execution | Preserve exact-version refusal. Source-build commit alignment is operator review, not wire enforcement. |
+| Owning manager controls rollout/repair/rollback/retention; preserve Python/npm/uv/pipx installations | Docs + operator attestation; named before/after static measurements where needed | No new authority; a marker/hash cannot establish ownership or current callers. |
+| Original #23 criterion: validate the selected workflow on isolated POSIX and Windows destinations | Separately scoped experiments after choosing the workflow and exact evidence cells | Remains open. Human review must decide how the checklist workflow addresses this criterion; no cell is completed here. |
+| Linux requalification under the ADR's later receipt/recovery rules and operator-check → receipt → unlock order | Inventory the historical debt before selecting any live experiment | Human decision required: retain the named historical checks, rescope them to checklist qualification, or record why a criterion is no longer needed. This proposal neither silently drops the debt nor requires a recovery engine. |
+| Windows destination matrix and other account/architecture/runtime/concurrency cells | Separate live experiment proposals per cell | Bounded historical evidence only; other cells remain unrun. |
+| F2–F6 capability/error/identity/provisioning follow-ups | Separate design/implementation review and validation | Proposals, not commands delivered here. No Windows-client jump qualification. |
+
+Historical anchors remain dated: the 2026-10-02 Debian 13 x86_64/glibc 2.41
+run used published TS 0.2.1 and Node 24.21.0/22.23.3 under then-current ADR rules, with incomplete
+operator ordering and later recovery rules unvalidated. The 2026-10-07 Windows
+10 x64 administrator/PowerShell 5.1 run used published 0.3.1 and Node 24.16.0:
+isolated offline installation, wrapper/native lock, operator SSH doctor and
+nonexistent-target dry-run, plus 31 native storage/local-wrapper fixtures. Only
+the primary installation had operator SSH evidence. Windows Node 22.23.3
+banner/native-lock smoke is separate from full installation qualification.
+See the ADR's dated validation sections and their [validation records](../../VALIDATION.md).
+CI/admin-only evidence and these checkpoints do not qualify complete platforms,
+current installations, Windows-client jump, delivery or ACK.
+
+## Design acceptance scenarios (review only)
+
+These are bounded paper scenarios, not commands or tests to execute.
+
+| Scenario | Required checklist behavior |
+| --- | --- |
+| Operator reviews metadata and declines diagnostics | Static predicates may pass; skipped diagnostics stay `not_checked`; no connection or executable run. |
+| Metadata version differs from the intended version | Version-match check fails; stop dependent diagnostics pending a human decision. |
+| Wrapper metadata declares Node A; a command reports Node B | Record the declaration and observed command as separate predicates. Fail agreement only if runtime B is bound to the selected wrapper; an unrelated PATH Node does not establish a conflict or the selected runtime. |
+| Hash cannot be read, or both recorded hashes are null | Comparison is unknown; never report unchanged or authorize deletion. |
+| Inspection method cannot interpret the selected native path/platform | Relevant check is unsupported with its limit; unaffected check results remain recorded. |
+| Authorized doctor exits 0 with `ready=false` | Completion may pass; the predicate “reported ready=true” fails for the recorded `--agent` selection. This flag is not installation integrity or proof of actual sendability, native locking, delivery or ACK. |
+| Authorized diagnostic times out or returns an unparseable result | Record unknown and stop; do not infer completion, submission or permission to retry. |
+| A remote command omits the selected wrapper path or Windows platform mode | Attribution is unknown; a same-version banner does not bind the selected installation. |
+| An old digest is explicitly selected and compared with a current measurement | Record a new comparison result and both observations' scope; never inherit the old check's pass or claim preservation throughout the interval. |
+| Old Windows success is offered for a different account/runtime or a current Linux cell | Keep the dated historical reference; current cell stays unassessed or unknown, according to whether assessment was attempted. |
+
+## Reporter extension decision and review gate
+
+The initial decision was checklist only. On 2026-10-21 the owner explicitly
+chose to extend it with a repository-only read-only reporter. The practical
+rationale is to reduce transcription mistakes in selected package-field and
+digest comparisons. No measured workflow pilot or time-saving claim is made.
+
+The [reporter contract](remote-qualification-reporter.md) is limited to explicit
+local file observations. Diagnostics, remote access, runtime/native execution,
+ownership, caller use and remediation remain outside the program. There is no
+new journal, receipt, lock, recovery engine or production CLI command.
+
+This authorizes the requested isolated implementation and review, not a merge,
+release, live experiment or closure of #23. Human PR review must still assess
+the implementation and remaining design choices. Additional functionality
+needs its own explicit scope; #155 remains deferred.
