server_version_num has two encodings: MMmmpp from PG 10, Mmmpp before it. The minor in the pre-10 form lives at (num/100)%100 — every copy of the old helper printed num%100, the PATCH level, so a 9.6.3 server rendered "postgres 9.3" (and 9.5.0 rendered "postgres 9.0") in the tune, vacuum, queries, tables, erd, advisor and report headers. Replace the duplicated pgLower/pgVersionShort with one model.PGVersionString (+ ServerInfo.ShortVersion) and migrate every caller, so the encoding can never drift apart again. Also drop agoStr's dead d<0 branch in vacuum.go (the d<time.Minute case already renders "just now").
…waits profile Two mismatches made the strip's lock status unmatchable: - The gauge printed queryHex4 (HIGH 16 bits of the query_id) while the waits profile, wait_lock_contention and query_slowdown all print queryTag (LOW 16). The two encodings differ for ~99.998% of ids, so "query XXXX" in the gauge matched nothing else in the report. - The gauge ranked by raw LockShare (share of a query's OWN samples) while topLockQuery right below it ranks by LockShare x Count (total lock samples) — same data, different winner. The gauge now selects via the profile's own topLockQuery and prints the same low-16 handle, so the strip and the section it summarizes always agree. queryHex4 is deleted.
buildBoard's contract says a row's status is taken from the finding that governs it, but the checkpoints, replication, WAL and settings rows were hardcoded ok — the --full board read "replication ok" while sync_rep_degraded (critical) and "settings ok" while fsync_off (critical) printed directly below it. The wraparound row also missed mxid_wraparound and the indexes row missed fk_unindexed/redundant_indexes. Every derived row now routes through statusFor with the full governing list (the same lists the checked line uses), so the board can never read ok over a finding on the same screen — and stays ok when clean.
The stall arm required LastArchivedTime != nil and the failing arm required a failure signal — an archive_command that HANGS (dead NFS mount, stalled TCP: it never returns, so no counter ever updates) on a server that has never archived fired NEITHER: WAL kept flowing, pg_wal filled, PITR silently never worked. Add the third arm: last_archived_time NULL + WAL flowing + server uptime past the stall threshold, gated so a recent pg_stat_reset() (which also NULLs the timestamp) cannot be misread as "never archived". Same critical severity, hang-specific wording and remediation (run the exact archive_command by hand — a hanging command updates nothing).
The blocker section printed "~N% of its sampled time in Lock" using the victim's share of the WHOLE sampling window (sess.Share): a backend blocked in 40 of 200 window samples read "~20%" when the truthful number is 100% — it was blocked every single time it was seen. BlockerEvidence already computes the honest per-PID fraction (fast-plane corroboration); carry it into BlockedVictim.LockShare (waits schema 1.1.0, additive) and print that. A victim the fast plane never sampled gets no line rather than a fabricated number.
schemaEvents and configEvents appended while ranging Go maps, so two runs over identical state produced the same events in different order — in the report, the stored snapshot and the AI payload. The codebase already polices this elsewhere (config.go sorts its warnings for exactly this reason). Sort schema events by (kind, object) and config events by object — (Kind, Object) is a total order since each object emits at most one event. Verified by re-deriving 200 times and comparing byte-for-byte.
isNotification was computed but only consulted in the default arm, so a
notification-form initialize / ping / tools/list / tools/call /
prompts/get / resources/read still got a reply — with "id": null, which
JSON-RPC 2.0 section 5.1 forbids ("The Server MUST NOT reply to a
Notification"), and a strict client drops the whole session over it.
Centralize the rule in a responder type: every handler funnels through
it, so no future method or error path can regress the guard. A
notification-form tools/call is still processed (fire-and-forget),
never answered.
…hemas The FK query selects from_schema/to_schema and then threw them away: Edge carried bare table names and FKTarget was "table.column". With public.orders and analytics.orders both present, every renderer keyed by bare name — RenderASCII's titleRow and RenderASCIIRow's byName map collapsed onto whichever box registered last, so the FK arrow pointed at the WRONG schema's table and the other rendered as an orphan island; a cross-schema FK could not be represented at all. Mermaid and the HTML SVG had the same collision. - Edge carries FromSchema/ToSchema; FromQual/ToQual are the identity - FKTarget is the qualified schema.table.column - all four renderers (ascii, row, mermaid, html) key, route and cross-reference by qualified identity - nameView displays the shortest unambiguous form: bare when unique, schema-qualified when duplicated (mermaid folds it to analytics_orders) - an edge whose endpoint cannot be resolved names nothing rather than silently re-routing to a same-named table elsewhere - collapse the byte-identical arrowhead if/else (a dead branch masking that direction is expressed by which row carries the glyph)
detectShift deliberately passes a zero baseline ("0 to anything is the
strongest shift there is"), but the chain builder computed ratio=0 for
Before==0: the symptom printed "slowed 0.0x" and impact = share*0 = 0,
sorting the strongest regression the detector can emit to the BOTTOM of
the report (and missing the large-shift confidence bonus).
A 0 -> X shift now says so ("went from ~0ms to X per call — used to cost
nothing, now costs real time") and is ranked with a documented finite
ceiling (zeroBaselineScore = 1000) so share still orders chains within
the same magnitude. Hop Before/After stay the honest 0 -> X.
…-txn footprint Rates: only health's samples bracket the runner window. The other counters (io, wal, iostats) sample in phase 1 (before the window opens) and phase 2 (after it closes), yet every Assemble divided by the shared window dt — inflating each rate by the phase lead+lag, worst on short intervals and remote databases. The runner now stamps each collector's own A/B times into sampled.Span and counter Assembles divide by rateWindow (own span, window fallback, never a non-positive interval). Own footprint: every pgbot read books a server transaction. Health subtracted the sampler's successful polls but leaked the rest: its own sample-A query commits inside the window (+1 commit per run — visible as TPS 0.2 on an idle database), and every aborted poll books a ROLLBACK — the exact counter high_rollback_ratio grades, inflated during exactly the lock storms that stall polls. Subtract own commits (polls + 1 when both samples succeeded) and aborted polls' rollbacks, clamped so a counter reset still reads as a reset.
…uidance Prometheus: two expired ignore rules produced two byte-identical suppression_expired series — duplicate label sets are INVALID in the text format, and a scrape (or promtool) rejects the whole file, taking every pgbot metric down with it. ExpiredFindings now carries the rule's identity including its expiry as Object so each series is distinguishable, and promFamily.add refuses a duplicate label set outright — exposition validity is the hard contract, and a dropped duplicate carries zero information loss. labelKey parses the label block quote-aware, since label values may contain braces. Config: the credential-guard error pointed at a --dsn flag and a PGBOT_DSN variable that do not exist anywhere. It now names the real interface: the positional connection string, $DATABASE_URL, $PGBOT_DATABASE_URL and $PGSERVICE.
…ck client mutation - sarif: securityScore's comment claimed it derived from Impact; the code (correctly) switches on severity class only — fix the comment. - logs: isSelfLogEntryForUser dropped EVERY client's "connection authenticated" line for pgbot's role. The line names neither PID nor application_name, so it cannot be attributed exactly; drop it only when the entry's timestamp proves it can be pgbot's (at/after the session start plus a 2-minute skew guard). When in doubt, keep the line — a kept line is noise, a dropped line is lost evidence. - bedrock: bedrockModel pinned CheckRedirect (and wrapped the transport) on the CALLER's *http.Client, leaking into every later call on a shared client. Operate on a shallow copy.
…fix status Full audit write-up: all 8 previously reported bugs confirmed (3 by execution against the real code), 6 new bugs found in the follow-up hunt (4 execution-verified), minor notes, the clean-area audit log, and the fix-status table mapping every fix to its file and regression test.

Test the actual skew-window interval.
Line 107 sets selfSince to nine minutes after the entry timestamp. This tests a pre-session entry, not an entry within two minutes after session start. Set selfSince to now so the entry is one minute into the guard window. The current test would still pass if the skew guard were removed.

Count only failures that caused a PostgreSQL rollback.
ash.failures includes Pool.Query failures that occur before backend acquisition. Those failures do not increment pg_stat_database.xact_rollback, but healthCollector.Assemble subtracts every OwnTxnFails value from the rollback delta. When workload rollbacks cover the subtraction, this removes real workload rollbacks and underreports rollback rates.
Keep sampler failures separate from rollback-causing failures. Set OwnTxnFails only for polls with a confirmed server-side rollback.

Exercise the rollback ratio with a workload delta.
The fixture becomes idle after pgbot transactions are removed. RollbackRatio == nil therefore passes this condition, so the test does not verify rollback-ratio correction.
Add workload commits and rollbacks to sample B. Then require a non-nil ratio with the expected window value.

Assert both suppression_expired series explicitly.
This fixture emits two pgbot_finding series and three pgbot_findings_total series. If one expired-rule series is missing, len(seen) is still at least four. Count the pgbot_finding series with id="suppression_expired" and require two, or assert both object labels.

minimal, and validate.
In `@internal/render/statusboard.go` at line 148, Update the status text selection
around statusFor("unused_indexes", "index_invalid", "redundant_indexes",
"fk_unindexed") so clean is shown only when unused_indexes governs the row; use
neutral text such as findings for other warning or failure findings, and add a
regression assertion covering non-unused findings without an unused index.

Do not display MaxXIDAge for every wraparound warning.
When mxid_wraparound or sequence_exhaustion triggers while transaction-ID age is normal, Line 170 still displays the normal transaction-ID value as the warning evidence. Render the metric for the governing finding, or use a neutral value when no comparable metric exists. Extend TestBoard_neverOkOverFindings to assert the displayed value.

In `@internal/render/statusboard.go` at line 165, Update the status rendering

MaxXIDAge is not displayed as evidence for mxid_wraparound or
sequence_exhaustion when transaction-ID age is normal; render the governing
finding’s metric or a neutral value when none applies. Extend
TestBoard_neverOkOverFindings to assert the displayed value.

Make the self-filter contract exact.
isSelfLogEntryForUser uses strict >: it drops only entries after selfSince + 2*time.Minute. bug_report.md says ≥, and tasks/todo.md says “at/after” with “±2m”. Align both records with the implementation and add the equality case to TestIsSelfConnUser; equality currently keeps the line.

In `@tasks/todo.md` at line 18, Align the self-filter documentation in
bug_report.md and tasks/todo.md with isSelfLogEntryForUser’s strict greater-than
boundary, stating that entries equal to selfSince plus the two-minute skew are
retained; add an equality-boundary assertion to TestIsSelfConnUser confirming
the line is kept.
