/** |
| 8 |
* Admin-mutation visibility gate (Phase 4 of the staged view-build watermark |
| 9 |
* refactor; see docs/refactor-staged-view-build-watermark.md and queue task |
| 10 |
* t_260516_140130_872). |
| 11 |
* |
| 12 |
* The single observable contract: after an admin clicks Save on the redirects |
| 13 |
* UI, the next AJAX fetch must NOT return a snapshot built before the |
| 14 |
* mutation, OR it must fall back to stale-serving once the sanity timeout |
| 15 |
* elapses (so a stuck cron does not block the admin redirects screen |
| 16 |
* forever). Before Phase 4 the gate was driven by a unix timestamp |
| 17 |
* comparison (`viewDoneMutationInvalidatedAt > viewDoneDataBuiltAt`). Phase |
| 18 |
* 4 swaps the inputs to watermark comparison: `built_watermark` (published |
| 19 |
* at S11 by the runner) vs `mutation_watermark_observed_by_admin_action` |
| 20 |
* (the post-increment value the admin's bump returned at click-Save time). |
| 21 |
* |
| 22 |
* Three options: |
| 23 |
* |
| 24 |
* - `wp_abj404_view_done_mutation_watermark_observed_by_admin_action`: |
| 25 |
* the post-increment watermark value the admin's bump returned. Set by |
| 26 |
* {@see markViewDoneInvalidatedByAdminMutation()}; cleared by |
| 27 |
* {@see markViewDoneBuildCompleted()} on success. |
| 28 |
* - `wp_abj404_view_done_mutation_watermark_observed_at`: wall-clock |
| 29 |
* timestamp paired with the observed value for the sanity-window |
| 30 |
* fallback. Same lifetime as the observed-watermark option. |
| 31 |
* - `wp_abj404_view_done_mutation_invalidated_at`: pre-Phase-4 timestamp |
| 32 |
* option. Read as a cold-bootstrap fallback when the watermark class is |
| 33 |
* not yet loaded (defensive guard); written by the same fallback path |
| 34 |
* so an upgraded install that hits a cold path still gates reads. |
| 35 |
* Cleaned up by {@see markViewDoneBuildCompleted()} for convergence. |
| 36 |
* |
| 37 |
* Comparison semantics (pinned by ViewDoneServeabilityWatermarkGateTest): |
| 38 |
* |
| 39 |
* - `built_watermark >= observed` releases the gate (the snapshot covers |
| 40 |
* the admin mutation). `>=`, not `>`, so a build that exactly covers |
| 41 |
* the observed watermark unblocks reads. |
| 42 |
* - The comparison uses the OBSERVED value, NOT the live counter |
| 43 |
* ({@see ABJ_404_Solution_MutationWatermark::current()}). Unrelated |
| 44 |
* later mutations on a busy site advance the live counter past the |
| 45 |
* admin's observed value; gating against the live counter would block |
| 46 |
* reads forever even after a covering build completed. |
| 47 |
* - The gate respects the same `VIEW_DONE_MUTATION_INVALIDATED_SANITY_ |
| 48 |
* SECONDS` upper bound the legacy timestamp gate did. After the window |
| 49 |
* elapses the gate falls back to fbc270d8 stale-serving + the |
| 50 |
* hard-stale admin notice; a stuck cron / broken build cannot block |
| 51 |
* the admin redirects screen indefinitely. |
| 52 |
* |
| 53 |
* Composition. Mixed into `ABJ_404_Solution_DataAccess` alongside |
| 54 |
* `ABJ_404_Solution_DataAccess_ViewQueriesStagedTrait` (which holds |
| 55 |
* `viewDoneIsServeable()` and consults this trait's reader helpers), |
| 56 |
* `ABJ_404_Solution_DataAccess_MutationWatermarkSeamTrait` (the |
| 57 |
* `bumpMutationWatermark()` source-mutation seam), and |
| 58 |
* `ABJ_404_Solution_DataAccess_ViewBuildStartedWatermarkTrait` (which |
| 59 |
* supplies `builtWatermarkOptionName()` + `readWatermarkOption()`). |
