List journal entries

[robzolkos]

Give Go SDK consumers typed, cursor-based access to personal Journal history and scoped search. The server contract is merged and verified in production; existing per-day Journal reads and mutations remain unchanged.

Review readiness: ✅ Yes — generated contract, wrapper coverage, CI, and production availability are verified
Risk: 🟡 Medium — this adds a generated API surface and cursor parsing consumed by the dependent TUI
Decision: None

✅ Change — Go callers can list, page, and search Journal entries

Before

Go SDK consumer
└── Journal service
    ├── read one known day
    └── ❌ cannot discover or search Journal history

After

Go SDK consumer
└── Journal.ListPage(page, query)
    ├── ✅ receive newest-first entries  ← CHANGED
    ├── ✅ pass NextPage to read older entries  ← CHANGED
    └── ✅ provide q to search Journal content  ← CHANGED

JournalPage returns typed recordings plus the geared cursor parsed from HEY's Link header. The caller starts with an empty page and decides whether to follow NextPage.

✅ Evidence — generation, conformance, wrapper behavior, and production compatibility are verified

• ✅ make check passed at this head, including 156 conformance checks.
• ✅ Unit coverage verifies query encoding, typed decoding, next-page extraction, and an empty cursor on the final page.
• ✅ Current-head GitHub checks cover Smithy verification, spec drift, API compatibility, Go tests/lint, conformance, CodeQL, Trivy, govulncheck, and gosec.
• ✅ A read-only production probe using this exact SDK head called JournalService.ListPage(ctx, "", "") successfully after the Haystack deployment.

make check
passed — 156 conformance checks

GOWORK=off go test ./pkg/hey -run Journal
passed

production JournalService.ListPage(ctx, "", "")
journal feed: ok entries=3 has_next=false

Behavioral proof: Journal wrapper tests · path conformance cases

✅ Scope — additive Journal listing only; existing SDK operations remain compatible

Included:

• Smithy ListJournalEntries operation with page and q
• OpenAPI and Go client generation
• JournalService.ListPage and JournalPage
• route, behavior, shape, coverage, and conformance artifacts

Preserved:

• JournalService.Get, GetContent, and Update
• existing authentication, account scope, retries, and response limits
• every existing generated client operation

Not included:

• automatic all-page collection
• a separate search method; search is the optional query argument
• server-side search pagination, which is outside this SDK PR

✅ Delivery — Haystack is merged and responding in production; no SDK runtime prerequisite remains

The server dependency, haystack#8655, is merged. A non-mutating call from this SDK head to production returned a valid JournalPage, confirming deploy ordering before review.

There are no migrations, backfills, feature flags, credentials, configuration changes, or new runtime dependencies. Rollback is removal of the additive operation before publishing, or a subsequent SDK release if already published.

⚠️ Review decision — focus on generated contract fidelity and cursor boundaries

Please begin with:

1. whether the Smithy operation accurately models HEY's query parameters, response, and retry behavior
2. whether JournalService.ListPage handles the first, intermediate, and final page without hiding pagination policy from callers

The deliberate boundary is one page per call. Search results use the server's bounded, unpaginated response and therefore return no NextPage.

✅ Review path — model, generated surface, wrapper, then drift/conformance artifacts

1. Smithy model — operation, inputs, output, pagination, and retry contract.
2. OpenAPI, behavior model, and generated Go client — generated contract surfaces.
3. Journal wrapper and tests — public Go API and cursor behavior.
4. Conformance runner, path cases, URL routes, excluded routes, route coverage, and shape fingerprint — generated drift and behavioral proof.
