Add human-led conversation learning loop

The allowance was derived from the adaptive trust level with no way to
change it, which made the dashboard's "1 / 2 today" unexplainable and
left no way to slow an account down or push one along.

`dailyLimit` is null by default, keeping today's adaptive behaviour. A
whole number between 1 and 50 overrides it and is enforced verbatim in
either direction — it can raise an account above what it has earned or
hold it below. The trust level keeps being tracked underneath and is
reported as `adaptiveAllowance`, so the earned figure stays visible next
to the override, and clearing the field hands pacing back to the ladder.

Raising the limit above the earned allowance does remove the adaptive
backoff after a bad comment, so the dashboard says exactly that where the
limit is set. It does not touch the pause on two consecutive removals, a
comment the public cannot see, or a captcha challenge: those are safety
stops rather than rate controls and no limit setting can disable them.

Also correct two things the page was saying badly. The allowance is now
labelled "used in last 24h" with the trust level shown as what it earns,
because it is a rolling window and not a midnight reset. And a
per-community cap above the account allowance now states how much of it
is actually reachable — "1 of 10 today" beside an account limit of 2 read
as far more headroom than existed, since caps distribute the allowance
rather than adding to it.

Verified against a local instance: override above and below the earned
allowance, unrelated saves preserving it, clearing it through the UI,
rejection of 0/51/2.5/non-numeric, and a limit failing to clear a pause.

Changes should reduce duplication through small factories/policies without hiding operational state or merging account-owned dependencies into process-global singletons.
+### Learning is derived and revocable
+
+Raw Matrix history remains authoritative. Event attribution, trajectories, decisions, retrieval selections, and evaluation runs are separate projections so attribution fixes and later safety outcomes can revoke examples without rewriting chat history.

+
+`dailyLimit` is null by default, which leaves the allowance to the adaptive trust level the verification sweep maintains (2/3/5/8/12 per day at levels 0-4). Setting a whole number between 1 and 50 overrides that in either direction and is enforced verbatim; the trust level continues to be tracked and reported as `adaptiveAllowance` so the earned figure stays visible. Raising the limit above the earned allowance removes the adaptive backoff after a bad comment, so the dashboard says so. It does not affect the removal/shadowban/captcha pause, which is a safety stop rather than a rate control and cannot be disabled by any limit.
+
+A per-community `dailyCap` only distributes the account allowance; caps are not additive and cannot raise the account total.
+
+Community weights feed a new weighted-random pick for each discovered growth thread. The grower queues only one new thread at a time, drains due retries and existing queue work before polling another community, and exposes an account-scoped queue clear that removes only unposted discovered/retryable rows.
+
+Browsing sessions are configured separately per account through `/api/growth/{accountId}/browsing` and reuse the enabled growth-community list and weights. Sessions default off with a configurable 3–6 selections-per-local-day range and a 60/40 post/comment split, respect quiet hours, and exclude NSFW unless enabled. The daily minimum, daily maximum, and selections per session accept positive whole numbers without a product-imposed upper ceiling; the maximum must not be lower than the minimum. The service derives one stable target inside the configured daily range for each account and local day. The operator also chooses a minimum gap of at least 45 minutes, and the service adds a random delay of up to `jitterMs` on top before persisting the next due time. A scheduled session is capped by the remaining daily target, while a manually requested session bypasses that target and uses the configured session size. `autoVoteEnabled` is a separate, default-off operator setting; it can submit selected upvotes only in running mode when browser dry-run is off. `nextDueAt` is service-owned durable state and cannot be set through the API.

+# Human-led conversation learning
+
+## Purpose
+
+The loop learns from the decision that caused a useful outcome, not merely from the last AI message before it. Manual interventions are first-class evidence because an operator may repair tone, timing, boundaries, or a media invitation before a recipient shares an image.
+
+## Pipeline and gates
+
+```text
+authoritative Matrix timeline
+  -> event attribution (exact > fingerprint > inferred)
+  -> outcome trajectory and causal credit
+  -> identifier-redacted decision examples
+  -> maturity / review / invalidation gates
+  -> account-scoped, quota-controlled retrieval
+  -> shadow audit or injected prompt context
+  -> offline evaluation record
+```
+
+Capture and use are independent. The default configuration captures and audits retrieval in shadow mode, but cannot affect generated replies. Injection requires both `generationEnabled: true` and `shadowMode: false`.
+
+## Attribution and credit
+
+Authoritative Matrix event IDs link openers, automated claims, dashboard manual sends, and exchange-library sends. Fingerprints support legacy backfill only. An unmatched outbound event is human-owned for the automation safety boundary, but inferred learning is held back when exact attribution is required.
+
+Credit classes are:
+
+- `human-created-success`: the human introduced the successful decision.
+- `human-improved-success`: AI attempted the step and the human replaced or improved it.
+- `human-completed-ai-trajectory`: the human intervention helped complete an AI-started exchange without directly making the media ask.
+- `autonomous-success`: the bounded automated policy made the attributed ask.
+- `recipient-initiated-media`: media arrived without an attributed ask.
+- `uncertain`: provenance is insufficient for causal use.
+
+Image receipt does not override a decline, boundary, or upsell outcome. Those outcomes invalidate the trajectory and all derived decisions. Operator exclusion is sticky across re-sync; explicit inclusion can reverse review/exclusion, but cannot resurrect an invalidated safety outcome.
+
+## Retrieval and evaluation
+
+Retrieval stays within the owning account, excludes the current room, filters confidence, prefers the same policy/stage/community, and fills separate human and autonomous quotas. Stored context is bounded and redacted. The generation ledger stores selected decision IDs, mode, policy version, and an optional prompt hash—not prompt text.
+
+`npm run learning:eval -- --db <path> --policy <version>` versions the current eligible dataset and enforces hard gates for leaked identifiers, invalid decision states, and empty outputs. Evaluation is deliberately local and deterministic. More subjective pairwise or model-graded evaluation can be added behind the same saved-run contract.
+
+## Infrastructure and framework boundary
+
+No new Dokploy service is required. SQLite, the existing backend, Matrix synchronization, OpenRouter client, and React dashboard are sufficient. Deployment needs only the normal application image plus a database backup before the migration; it does not require a vector database, queue, object store, or hosted tracing system.
+
+The repository/provider/evaluation interfaces are the framework seams. A hosted platform such as Langfuse or an experiment tool can later receive generation and evaluation records, and DSPy-style optimization or model fine-tuning can consume exported reviewed examples. None is placed in the online reply path until volume, evaluation quality, and operational need justify the extra infrastructure.
+
+## Rollout
+
+1. Deploy with capture enabled, generation disabled, and shadow mode enabled.
+2. Run a full chat sync to backfill authoritative histories.
+3. Review inferred and fingerprint-attributed trajectories in `/learning`.
+4. Let examples mature and run the offline evaluation against a backup/non-production copy.
+5. Compare human, autonomous, and recipient-initiated cohorts; do not blend them into the opener strategy metric.
+6. Enable generation while retaining shadow mode to exercise selection/auditing.
+7. Only after review and evaluation, turn shadow mode off for a small account/policy cohort; rollback is setting it true again.
+
+Starting, restarting, deploying, or enabling the live bot remains a separate explicit operational action.

+## Browsing session flow
+
+After reply handling, response checks, and comment-growth work, an enabled account may run one due browsing session. The durable `next_due_at` gate survives restarts; each completed attempt schedules the next one at the operator's minimum gap plus bounded random jitter, moved past quiet hours when necessary. The session picks one configured growth community by weight, reads its hot listing through the shared Reddit request coordinator, optionally reads typed top-level comments, applies deterministic exclusions, and only then selects up to the configured session size without replacement. Scheduled sessions cannot select beyond the remaining deterministic daily target.
+
+Each terminal selection is recorded as pending in SQLite before its remote write, so an interrupted or uncertain vote is never retried. With the separate automatic-upvote setting enabled, running mode sends authenticated Reddit `api/vote` requests sequentially through the same browser transport and shared coordinator as growth comments, then marks each audit record `submitted` only after Reddit confirms it; safe failures become `failed`. Scan mode and browser dry-run record `simulated` selections; stopped mode performs no discovery or decision work. Reddit 429 responses extend the shared cooldown, while ordinary read failures remain isolated from replies and comment growth. An operator can also run one immediate session for an enabled, running account: it bypasses the due, quiet-hours, and normal daily-target gates, uses the configured session size, preserves content exclusions, and follows the same automatic-upvote and dry-run rules.

 ## Reply-first conversation automation
 
 Explicit bot clients can send to a username through `POST /api/v1/messages` or the MCP `send_message_to_user` tool without selecting an account. The selector compares cached conversations case-insensitively and reuses the account that most recently interacted with that recipient. If no conversation exists, it chooses an authenticated running account with no invitation cooldown, preferring the lowest hourly send count. The selected account's normal rate limiter still owns the send. An API reply to an existing conversation marks automation as user-overridden so autonomous replies do not race the external caller.

+## Human learning loop
+
+After a room has an authoritative Matrix timeline, `ChatService` records the canonical response outcome and invokes the account-scoped learning observer. The observer:
+
+1. reconciles opener, automation-claim, exchange-library, manual-dashboard, recipient, and legacy events;
+2. stores text-minimising event provenance with an attribution confidence;
+3. finds received-image outcomes and the manual decisions that preceded them;
+4. assigns human-created, human-improved, human-completed, autonomous, recipient-initiated, or uncertain credit;
+5. stores bounded, identifier-redacted decision context; and
+6. leaves new trajectories provisional until the maturity window passes.
+
+Full chat synchronization naturally backfills older rooms. Upserts are keyed by account, room, and outcome event, so the pass is repeatable. A later negative canonical outcome invalidates both the trajectory and every derived decision.

 The account-growth page states plainly that comments are AI-written and posted without review, shows the adaptive allowance and trust level rather than a settable rate, and surfaces every posted comment's exact text alongside its score and removal state. A paused account replaces the pause control with a resume control and explains why it stopped, because resuming is the one action that can compound the damage.
 
+Its browsing section separates session scheduling from the default-off automatic-upvote switch, lets the operator set the daily target range, minimum gap, and selections per session, and shows whether each selection was submitted or simulated, today's deterministic target, post/comment split, exclusion counts, durable next session, and recent selections with Reddit permalinks. Daily and per-session counts have no product-imposed upper ceiling. The daily range is saved atomically; changing it recalculates today's target, which then remains stable for that range and local day. The displayed minimum gap is followed by bounded random jitter. Scan mode and browser dry-run remain simulation-only. An enabled, running account can also run one immediate session at the configured size; it bypasses the schedule and follows the same automatic-upvote setting. Enabling browsing does not enable comment growth or bot processing.

 Prepared cards in the authenticated outreach funnel expose the exact opener, grounded image analysis, attractiveness and physique scores, current target range, detected gender, strategy/tone/model metadata, and original source image. The live range is returned through the existing preparation field so cached dashboard bundles remain compatible during a rolling deployment. The durable queue still owns the historical preparation snapshot used for reconciliation.

+- The daily allowance is adaptive by default: it starts at two comments per day and only rises while comments demonstrably survive and earn upvotes, and a removal or a heavily downvoted comment lowers it immediately. An operator may override the figure per account; doing so replaces the adaptive backoff but not the pause below, and the dashboard states that trade-off where the limit is set.
 - Two consecutive removals, a comment invisible to signed-out visitors, or a captcha challenge pauses the account until an operator clears it. A failed visibility probe proves nothing and never pauses anything.
 - One comment per thread across every owned account, a per-community daily cap, quiet hours, and jittered spacing.
+- Due retries run before untouched queued threads, and any pending retry blocks new discovery until it is resolved or ages out. Discovery queues one thread from a fresh weighted-random community pick, avoiding predictable same-community batches.
 - Reddit's own refusals are authoritative: a community ban disables that community for that account, a throttle backs off at the scope Reddit named, and a signed-out response invalidates the session rather than being retried.
 - Growth deliberately continues while an account is held out of outbound messaging, because building the history is what lifts that hold. It is always the lowest-priority work an account performs, after inbound replies.
 - Dry run prepares and records a comment but never posts it. Every posted comment, and every comment refused by either gate, is kept with its reason in the growth audit trail.
 
+Browsing sessions are a separate, disabled-by-default account-growth experiment. They select a conservative number of eligible posts or comments from the same configured communities. The per-account automatic-upvote switch is separately disabled by default; when enabled, a selected item is upvoted through the account's authenticated browser session only in running mode and outside browser dry-run. Owned-account content, outreach recipients, cross-account duplicates, growth-comment threads, promotion experiments, moderator content, closed or removed threads, old or low-context items, and NSFW content unless explicitly allowed are excluded before randomness is applied. Every selection records whether the vote is simulated, pending, submitted, or failed, and browsing never affects the adaptive comment-growth trust level.

+### Human-led conversation learning
+
+A received image is an outcome, not proof that the preceding AI action caused it. The learning loop therefore attributes every Matrix event before extracting an example and gives manual interventions their own credit classes: human-created, human-improved, and human-completed AI trajectories. Autonomous and recipient-initiated outcomes remain separate comparison cohorts.
+
+Only privacy-redacted decision context is retained as learning material. Media bytes, private attachment paths, raw prompts, usernames, URLs, email addresses, and phone numbers are not copied into examples. Exact Matrix event IDs are preferred; fingerprint or inferred histories are held for review according to `learning.minimumAttributionConfidence`.
+
+Examples mature only after the configured delay. Later declines, boundaries, or upsell classifications revoke the trajectory. An operator can explicitly include or exclude a trajectory in **Learning review**. Generation use is independently gated and defaults to capture-only shadow mode, so collecting evidence cannot silently change live replies.
