 ## 0.26.7
 - Add HOT and COLD cache occupancy progress bars on `/cache` for configured object and byte limits, with explicit percentage/limit details.
 - Verify cache `Age` progression on stored HITs, protect `Age` from custom response-header rules, and clarify that successful validator revalidation legitimately restarts the HTTP freshness age while `X-Cache-Resident-Age` continues to grow.
 - Restore downstream compression for cookie-bearing responses only when RustProxy is serving a shared-cache HIT already accepted by cache policy or a local static Web Server response; privacy-sensitive dynamic/cookie responses remain excluded.
 - Keep `Content-Encoding`/`Vary: Accept-Encoding` negotiation for gzip, Brotli, Zstandard and deflate, and make the bundled compression tester stop forcing `Cache-Control: no-cache` unless explicitly requested.
 - Preserve compatible backend upstream clients across unrelated active-snapshot rebuilds so generation age, generation request count and rotation totals do not reset spuriously.
 - Keep age-based and request-count upstream client recycling active while making long-running rotation diagnostics reliable.
 - Update the OCI image to ship Certbot with the supported Cloudflare, OVH and RFC2136 DNS plugins in one pinned Python environment, and refresh container/install documentation.
 - Keep SQLite schema 8 and saved proxy configuration compatibility with 0.26.6.
 ## 0.26.6
 - Persist and reapply backend diagnostics column and sorting preferences as account-scoped user preferences.

 - Show explicit HOT and COLD cache occupancy progress on `/cache`, including object-count and byte/disk limits from Cache settings plus percentage usage.
 - Preserve compatible upstream client pools across unrelated active-snapshot rebuilds so generation age, request count and `Rotations` diagnostics do not restart at zero unless the backend connection policy actually changes.
 - Keep age-based backend rotation in the maintenance loop and retain request-count rotation; compatible snapshot reuse now makes the existing counters observable over long-running processes.
 - Refresh container documentation and ship the OCI image with one pinned Certbot environment containing all RustProxy-supported DNS plugins: Cloudflare, OVH and RFC2136.
 - Review current installation/container/cache/backend lifecycle documentation for stale version or behavior statements.
 - Keep SQLite schema 8 and the saved proxy configuration format unchanged; upgrading from 0.26.6 requires no data migration.

 ### Retained 0.26.6 release notes
 - Keep backend diagnostics visible-column selection, sort key and sort direction synchronized with the account-scoped administrator preferences whenever preferences are loaded or updated.
 - Clear the ACME certificate-creation form after the issuance job finishes successfully, so successful certificates do not leave stale values while failed jobs keep the non-secret form values available for correction.

 ## 0.26.7 - Cache occupancy and backend rotation continuity
 Current direction: 0.26.6 -> 0.26.7
 - [x] Show HOT/COLD cache occupancy progress against configured entry and byte limits on `/cache`.
 - [x] Preserve compatible upstream client generations across unrelated runtime snapshot rebuilds so rotation age/counters remain continuous.
 - [x] Keep request-count and age-based backend client recycling covered by tests and visible diagnostics.
 - [x] Refresh container documentation and include all supported Certbot DNS plugins in the shipped OCI image.
 - [x] Review current installation/cache/backend lifecycle documentation for stale behavior statements.
 - [x] Keep SQLite schema 8 and saved proxy configuration compatibility with 0.26.6.
 - [ ] Run compiler-enabled `cargo fmt --all`, `cargo check --locked --all-targets` and `cargo test --locked --all-targets` on a Rust release host.

 # Changelog
 ## 0.26.7
 ### Backend client lifecycle and cache diagnostics
 - Preserve compiled upstream clients when an active-snapshot rebuild leaves the backend origin, address policy, keepalive policy and connect timeout unchanged. This retains Hyper connection pools together with generation age, per-generation request counters and cumulative rotation totals instead of resetting those diagnostics on unrelated configuration rebuilds.
 - Keep incompatible backend changes isolated: changing the origin or any client-construction input still creates a fresh upstream client and fresh generation state.
 - Add a pool regression proving compatible snapshot rebuilds reuse the existing backend/client object; existing upstream-client tests continue to cover age-triggered recycling.
 - Extend `/cache` with explicit HOT and COLD occupancy meters for both configured object limits and byte/disk budgets. Percentages are clamped for progress rendering while the raw counters remain visible.
 ### Container certificate tooling
 - Build the OCI runtime image with a dedicated Certbot virtual environment containing the Cloudflare, OVH and RFC2136 DNS plugins supported by RustProxy, all pinned with the same Certbot release.
 - Refresh container documentation so it no longer tells operators that those provider plugins must be added separately.

-Rust-independent contracts require the shared preference application path to reapply backend table state, the ACME UI to defer form reset until the matching issue job succeeds, the NPM migration documentation to ship and mount all three helper modules, frontend/location routing to use the composed IP/country ACL evaluator, and the ACL profile editor to retain its guided modes, preview and IP normalization path. Rust unit coverage in `src/acl/tests.rs` exercises allow-country OR allow-IP, block-country OR deny-IP, explicit deny precedence and plain IPv4/IPv6 host rules, but those Rust tests require a compiler-enabled release host.
+Static source contracts require all four `/cache` occupancy meters (HOT objects, HOT bytes, COLD objects and COLD bytes) and their configured-limit inputs. Browser JavaScript syntax is checked with Node.
-Source contracts additionally require the Linux environment classifier, LXC-only uptime/load override, PID 1 start-time parser and Process UI `Linux / <environment>` composition. Rust unit coverage includes LXC-vs-VM precedence, VM/host classification, LXCFS proc detection, `/proc/loadavg` parsing and PID 1 stat parsing.
+The existing upstream-client unit coverage retains age-triggered rotation without user traffic. A new pool regression, `compatible_pool_rebuild_reuses_upstream_clients`, verifies that a compatible rebuild reuses the previous compiled backend/client object so rotation state remains continuous. Source contracts also require the `reusable_with` compatibility check, maintenance calls for normal/WebSocket clients and backend reuse path. These Rust tests require a compiler-enabled release host.
-Existing source, security, memory, Web Server, documentation, packaging, upgrade, SQLite migration and administration JavaScript contracts remain enabled.
+Cache regressions now require a stored HIT/dashboard object to advance `Age`, while compression regressions require `Age` to survive encoding and require cookie-bearing compression to stay blocked unless the internal cache/static safety marker is present. Source contracts protect the `Age` header from custom response rules and require the bounded HIT/static cookie-compression exception. The bundled compression tester no longer forces `Cache-Control: no-cache` unless `--revalidate` is requested.
-A compiler follow-up also removes a redundant route-level `country_resolved = true` write reported as `unused_assignments`; the write occurred after the flag's final read and therefore does not change GeoIP or ACL behavior.
+Documentation checks cover the 0.26.7 release note, Reader index, local Markdown links, cache diagnostics and container/ACME provider guidance. Packaging smoke tests verify the 0.26.7 release identity and deterministic source archive contract.

 # RustProxy 0.26.7 implementation note
 ## Scope
 0.26.7 is a compatibility-preserving cache observability, backend lifecycle and container documentation patch on top of 0.26.6. SQLite remains schema 8 and the saved proxy configuration document is unchanged.
 ## HOT/COLD cache occupancy
 The authenticated `/cache` page now renders explicit occupancy meters for both cache tiers. HOT and COLD object cards compare the current entry count with `max_entries` / `cold_max_entries`; HOT memory compares charged HOT bytes with `max_bytes`; COLD disk compares persisted bytes with `cold_max_bytes`. The cards also show the configured limit and percentage so the progress bars remain interpretable without estimating from the visual fill alone.
 The HOT byte meter intentionally uses allocated/charged HOT bytes, not only logical body length. This matches the budget enforced by cache admission. COLD uses persisted storage bytes.
 ## Backend rotation continuity
 Age-based recycling continues to run from the backend maintenance loop and request-count recycling remains request-driven. The isolated client rotation logic already advanced generation and rotation counters correctly.
 The release fixes a separate observability/lifecycle problem: rebuilding an otherwise compatible active routing snapshot created a new upstream client object, which restarted generation age, request count and rotation totals at zero. Pool rebuilds now retain the previous compiled backend when both ordinary and WebSocket upstream clients have exactly the same client factory: backend definition, address policy, keepalive settings, protocol mode and connect timeout. Health observations retain their existing compatibility rules independently.
 A real backend-policy change still creates a fresh client. This avoids retaining stale DNS/listener safety policy, TLS identity, keepalive or timeout behavior while keeping long-running rotation diagnostics continuous through unrelated snapshot publications.
 ## Container certificate tooling and documentation
 The OCI runtime image now creates a dedicated `/opt/rustproxy-certbot` Python environment and pins Certbot plus the supported Cloudflare, OVH and RFC2136 DNS plugins to the same release. The image therefore supports every certificate provider exposed by RustProxy without an extra image-extension step. Container documentation was refreshed to remove the obsolete statement that DNS plugins are absent and to use the current release tag in examples.
 Current cache, vhost/backend and installation documentation was reviewed alongside the release notes so the dashboard limits, rotation semantics and container prerequisites describe the implemented behavior.
 ## Compatibility
 - SQLite schema: 8, unchanged.
 - Saved configuration format: unchanged.
 - No migration is required from 0.26.6.
 - Backend rotation counters intentionally restart when the backend client policy itself changes.
 ## Cache Age and downstream compression follow-up
 The cache freshness clock remains RFC-oriented: ordinary stored HITs advance `Age` from
 `initial_age + resident elapsed time`, while a successful validator revalidation starts a
 new freshness calculation. `X-Cache-Resident-Age` remains the monotonic residency clock
 across revalidation and tier movement. `Age` is now protected from generic response-header
 rules, and regression coverage explicitly checks that both the wire HIT header and `/cache`
 object age advance from the stored clock.
 Compression still refuses Authorization, private/no-store/no-transform, Set-Cookie, ranges,
 SSE, upgrades and already encoded responses. Cookie-bearing requests now have one bounded
 exception: a response can be compressed when it is already a shared-cache HIT accepted by
 cache policy or a local static Web Server response. This aligns the static-cookie cache
 exception with downstream compression without enabling compression for arbitrary dynamic
 cookie responses. The bundled compression tester no longer sends `Cache-Control: no-cache`
 by default because that header forces validator revalidation and can make cache `Age` appear
 to stay at zero; `--revalidate` retains the old diagnostic behavior explicitly.
