docs(spec): align saas-api.md with deployed worker (LAB-677) - #50
docs(spec): align saas-api.md with deployed worker (LAB-677)#5027Bslash6 wants to merge 2 commits into
Conversation
The spec's own rule is "the implementation is authoritative"; five claims
contradicted the shipped worker (cachekit-io/saas apps/cache/), verified
against source in this change:
- DELETE /v1/cache/{key}: no 404 path exists — delete is idempotent and
unconditional, always 200 {"success": true} (index.ts 'delete' case).
- GET /v1/cache/health: body is {"status","cache_entries","active_locks"}
from TenantCacheStore.health(), not {"version":"1.0.0"}.
- TTL omitted on PUT: entry is stored with no expiry (expiresAt = null,
durable-object.ts); no tenant-default-TTL mechanism ships.
- HEAD /v1/cache/{key}: always 200; existence is signalled solely by the
presence of X-CacheKit-Freshness (HTTP forbids HEAD bodies, so the
internal {"exists":bool} body never reaches the wire). SWR window table
and error-classification tables updated to match (404 is GET-only).
- Authentication: accepted prefixes are ck_sdk_/ck_api_/ck_live_
(cache-auth.ts:108) with the L1-header requirement and ns:/nsapi:
write-space split; ck_test_ never authenticated.
Also drops the 201/204 rows the worker never emits for writes/deletes
(204 is CORS preflight only).
docs.cachekit.io already documents the real behavior for all five
(LAB-664, docs#8) — this is spec-text only.

Important Approval pendingCodeRabbit has no unresolved comments, but it could not review the latest commit because the review limit was reached. Follow the review guidance in this comment to continue. WalkthroughThe SaaS API specification updates authentication rules, TTL omission behaviour, endpoint status semantics, SWR eviction responses, health data, and cache-miss classification. ChangesSaaS API protocol
Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🟡 Moderate · up to This documentation-only change corrects several API descriptions, but the current specification still leaves no-expiry TTL semantics and OPTIONS authentication requirements undefined while retaining contradictory status wording. Clients could implement incorrect TTL, preflight, or error handling, so the contract should be clarified before merge. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

- Line 163: Qualify the unconditional success response in the delete endpoint
description: state that 200 with {"success": true} applies only after
authentication and authorisation succeed, while preserving the existing 401 and
403 error behavior.
- Line 208: Update the SWR lifecycle diagram in the API specification to
separate the post-evict_at outcomes: show GET returning 404 and HEAD returning
200 without the X-CacheKit-Freshness header, removing the shared GET / HEAD 404
path.
- Line 128: Update the TTL contract in the cache behavior documentation to
define GET and HEAD freshness for entries with expiresAt = null, and specify the
exact GET /v1/cache/{key}/ttl response including whether ttl is null or omitted.
Revise the associated rationale so it does not claim the 30-day maximum bounds
storage for no-expiry entries.
- Line 56: Update the ck_sdk_ authentication requirements in the specification
to explicitly define the OPTIONS/CORS preflight exception: state whether OPTIONS
bypasses Bearer authentication and X-CacheKit-L1-Status validation, and document
the headers required for a successful 204 preflight response.

…piry contract, DELETE 200 qualifier, SWR diagram HEAD split (LAB-677) All four defined against the deployed worker source: - OPTIONS handled pre-auth (index.ts): unconditional 204, exempt from Bearer and X-CacheKit-L1-Status; CORS headers only for allowlisted origins. - No-expiry contract (durable-object.ts): permanently fresh reads; GET /ttl 404s (getTTL returns null -> 404, indistinguishable from absent key); PATCH /ttl gives a no-expiry entry its first expiry. Rationale no longer claims the 30-day cap bounds no-expiry storage. - DELETE 200 qualified as post-auth/authz; 401/403/400 still apply. - SWR lifecycle diagram splits post-evict_at outcomes: GET 404 vs HEAD 200 without freshness header.

Fixes five spec-vs-implementation drifts in
